FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with atherosclerosis is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about atherosclerosis, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to atherosclerosis, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on atherosclerosis. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to atherosclerosis, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on atherosclerosis. The Editors

CHAPTER 1. STUDIES ON ATHEROSCLEROSIS Overview In this chapter, we will show you how to locate peer-reviewed references and studies on atherosclerosis.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and atherosclerosis, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “atherosclerosis” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
Is Insulin Sensitivity a Causal Intermediate in the Relationship Between Alcohol Consumption and Carotid Atherosclerosis?: The Insulin Resistance and Atherosclerosis Study Source: Diabetes Care. 25(8): 1425=1431. August 2002. Contact: Available from American Diabetes Association. 1701 North Beauregard Street, Alexandria, VA 22311. (800) 232-3472. Website: www.diabetes.org. Summary: An association has been demonstrated between alcohol consumption and atherosclerosis. Insulin resistance, also a risk factor for atherosclerosis, has been shown to have a similar association with alcohol intake. This raises the question of whether insulin sensitivity is a causal intermediate in the alcohol-atherosclerosis relationship. This article reports on the Insulin Resistance Atherosclerosis Study, a multicenter cohort

Atherosclerosis
study designed to investigate relationships among insulin sensitivity, risk factors for cardiovascular disease, and carotid artery atherosclerosis. A J-shaped association was observed between alcohol consumption and common carotid artery intimal medial thickness. The protective aspect of the alcohol-atherosclerosis relationship was attenuated by 25 percent after the adjustment for insulin sensitivity. However, an interaction was observed between alcohol consumption and glucose tolerance (GT) status. In comparison with never-drinkers, all levels of alcohol consumption were associated with less atherosclerosis in participants with normal GT status. Participants with impaired GT status (but not diabetes) demonstrated a J-shaped alcoholatherosclerosis association. All levels of alcohol consumption were association with more atherosclerosis in participants with diabetes. These findings contrast with previous reports and do not support current recommendations regarding moderate alcohol consumption in people with diabetes. The authors call for more research to clarify this issue. 2 figures. 1 table. 43 references. •
Is Atherosclerosis Different in Patients with Type 2 Diabetes?: The Role of Fibrinolysis Source: Practical Diabetology. 20(2): 7-9, 12-14. June 2001. Contact: Available from R.A. Rapaport Publishing, Inc. 150 West 22nd Street, New York, NY 10011. (212) 989-0200 or (773) 777-6801. Summary: Atherosclerosis and cardiovascular disease in people with diabetes aredifferent from those in nondiabetic persons in several important respects. Mortality (death rate) is higher in patients with diabetes after undergoing percutaneous transluminal coronary angioplasty (PTCA) or coronary artery bypass grafting (CABG). A higher rate of re-stenosis after stent placement and compositional differences in atheroma make plaques more subject to rupture and more likely to cause sudden cardiac death in patients with diabetes. A higher level of plasminogen activator inhibitor 1 (PAI 1) in patients with diabetes appears to be one important factor contributing to these differences. This article focuses on the potential role of PAI 1 in atherogenesis (the development of atherosclerosis) and its interaction with other factors associated with diabetes and insulin resistance. Numerous studies have shown that lifestyle modifications and lipid lowering medications yield significant reductions in cholesterol; lipid lowering in turn markedly reduces the incidence of cardiovascular events over a 3 to 5 year period. The author reviews research on the use of insulin sensitizers (drugs) pioglitazone and rosiglitazone as another potential approach to address the pathophysiologic mechanisms in the formation of unstable plaques. Long term studies with insulin sensitizers are needed to determine whether they can in fact reduce cardiovascular mortality and morbidity in patients with type 2 diabetes. 7 figures. 16 references.

Diabetes and Atherosclerosis: Epidemiology, Pathophysiology, and Management Source: JAMA. Journal of the American Medical Association. 287(19): 2570-2581. May 15, 2002. Summary: Complications of atherosclerosis (fat buildup in the major arteries of the body) cause most morbidity (complications) and mortality (death) in patients with diabetes mellitus. Despite the frequency and severity of disease, proven medical therapy remains incompletely understood and underused. This article reports on a study undertaken to review the epidemiology, pathophysiology, and medical and invasive treatment of atherosclerosis in patients with diabetes mellitus. The authors performed a

computerized literature search (1976 through 2001); additional data sources included bibliographies of identified articles and preliminary data presented at recent cardiology conferences. Their data synthesis shows that diabetes mellitus markedly increases the risk of myocardial infarction (heart attack), stroke, amputation, and death. The metabolic abnormalities caused by diabetes induce vascular dysfunction that predisposes this patient population to atherosclerosis. Blood pressure control, lipidlowering therapy, ACE inhibitors, and antiplatelet drugs significantly reduce the risk of cardiovascular events. Although patients with diabetes can undergo revascularization procedures because of acute coronary syndromes or critical limb ischemia (lack of blood flow), the outcomes are less favorable in this population than in nondiabetic cohorts. The authors conclude that since most patients with diabetes die from complications of atherosclerosis, they should receive intensive preventive interventions proven to reduce their cardiovascular risk. 2 figures. 3 tables. 168 references. •
Factor Analysis of Metabolic Syndrome Using Directly Measured Insulin Sensitivity: The Insulin Resistance Atherosclerosis Study Source: Diabetes. 51(7): 2642-2647. July 2002. Contact: Available from American Diabetes Association. 1701 North Beauregard Street, Alexandria, VA 22311. (800) 232-3472. Website: www.diabetes.org. Summary: Factor analysis, a multivariate correlation technique, has been used to provide insight into the underlying structure of metabolic syndrome, which is characterized by physiological complexity and strong statistically intercorrelation among its key variables. This article reports on a study that investigated, using factor analysis, the clustering of physiologic variables using data from 1,087 nondiabetic participants in the Insulin Resistance Atherosclerosis Study (IRAS). This study includes information on the directly measured insulin sensitivity index from intravenous glucose tolerance testing among African-American, Hispanic, and non-Hispanic white subjects aged 40 to 69 years at various stages of glucose tolerance. Factor analysis identified two underlying factors among a group of metabolic syndrome variables in this dataset. Analyses using surrogate measures of insulin resistance suggested that these variables provide adequate information to explore the underlying intercorrelational structure of metabolic syndrome. Additional clarification of the physiologic characteristics of metabolic syndrome is required as individuals with this condition are increasingly being considered candidates for behavioral and pharmacologic (drug) intervention. 6 tables. 38 references.

Impact of Simultaneous Pancreas and Kidney Transplantation on Progression of Coronary Atherosclerosis in Patients with End-Stage Renal Failure due to Type 1 Diabetes Source: Diabetes Care. 25(5): 906-911. May 2002. Contact: Available from American Diabetes Association. 1701 North Beauregard Street, Alexandria, VA 22311. (800) 232-3472. Website: www.diabetes.org. Summary: Mortality (death) in type 1 diabetes patients with end stage renal failure is high and is dominated by coronary (heart) atherosclerotic events. With regard to prognosis, simultaneous transplantation of pancreas and kidney (SPK) may be superior to kidney transplantation alone (KTA) in these patients, because normalization of blood glucose levels may reduce progression of coronary atherosclerosis and because it is well known that progression of coronary atherosclerosis is one of the major factors that determines clinical prognosis. This article reports on a study that compared progression

Atherosclerosis
of coronary atherosclerosis in patients with (n = 26) and those without (n = 6) a functioning pancreas graft after SPK. Mean follow up was 3.9 years. Average glucose control was significantly worse for the patients without a pancreas graft than for patients with a functioning pancreas graft. Regression of atherosclerosis occurred in 38 percent of patients with a functioning pancreas graft compared with 0 percent of patients in whom the pancreas graft was lost. The authors conclude that this observation is an important part of the explanation for the observed improved mortality rates reported in type 1 diabetes patients with end stage renal failure after SPK compared with KTA. In light of these findings, the authors recommend that SPK be carefully considered for all diabetes transplant candidates. 3 figures. 1 table. 40 references. •
Serum and Dietary Magnesium and the Risk for Type 2 Diabetes Mellitus: The Atherosclerosis Risk in Communities Study Source: Archives of Internal Medicine. 159(18): 2151-2159. October 11, 1999.

[email protected]. Summary: This article describes a prospective cohort study that examined the association between serum magnesium level and dietary magnesium intake and the subsequent risk for incident type 2 diabetes in a cohort of 12,128 middle aged adults without diabetes from the Atherosclerosis Risk in Communities Study during 6 years of followup. Fasting serum magnesium level, categorized into six levels, and dietary magnesium intake, categorized into quartiles, were measured at the baseline examination. Incident type 2 diabetes was defined by self report of physician diagnosis, use of diabetic medication, fasting glucose level of at least 7.0 mmol/liter, or nonfasting glucose level of at least 11.1 mmol/liter. The study found that, among white participants, a graded inverse relationship between serum magnesium levels and incident type 2 diabetes was observed. From the highest to the lowest serum magnesium levels, there was an approximately two fold increase in incidence rate. This graded association remained significant after simultaneous adjustment for potential confounders, including diuretic use. Compared with individuals with serum magnesium levels of 0.95 mmol/liter or greater, the adjusted relative odds of incident type 2 diabetes rose progressively across the following lower magnesium categories: 1.13, 1.20, 1.11, 1.24, and 1.76. In contrast, little or no association was observed in African American participants. No association was detected between dietary magnesium intake and the risk for incident type 2 diabetes in African American or white participants. The article concludes that, among white participants, low serum magnesium was a strong, independent predictor of incident type 2 diabetes. That low dietary magnesium intake did not confer risk for type 2 diabetes implies that compartmentalization and renal binding of magnesium may be important in the relationship between low serum magnesium levels and the risk for type 2 diabetes. 1 figure. 5 tables. 52 references.

Summary: This article describes a study that investigated whether inflammatory markers predict the development of type 2 diabetes. The study population consisted of 12,330 men and women, aged 45 to 64 years, who were followed for a mean of 7 years. The association between different markers of acute inflammation and subsequent diagnosis of diabetes were analyzed. In a subgroup of 610 individuals selected originally for an unrelated atherosclerosis case-control study, diabetes associations with total sialic acid and orosomucoid, haptoglobin, and alpha1-antitrypsin were also investigated. During the follow-up period, 1,335 new cases of diabetes were detected. Adjusted odds ratios for developing diabetes for quartile extremes were 1.9 for raised white cell count, 1.3 for low serum albumin, and 1.2 for raised fibrinogen. In the subgroup analysis, individuals with concentrations of orosomucoid and sialic acid of more than the median had odds ratios of 7.9 and 3.7, respectively. Adjustment for body mass index and waistto-hip ratio lessened the associations. Those for white cell count, orosomucoid, and sialic acid remained significant. The article concludes that markers of inflammation are associated with the development of diabetes in middle aged adults. Although autoimmunity may partly explain these associations, they probably reflect the pathogenesis of type 2 diabetes. A better understanding of cytokine actions and interactions with other factors in the pathogenesis of type 2 diabetes may lead to improved understanding of its causes and open new approaches for its prevention. 5 tables. 30 references.

Promise of Primrose? Can Evening Primrose Oil Prevent Nerve Damage and Atherosclerosis? Source: Diabetes Forecast. 52(11): 40-42. November 1999. Contact: Available from American Diabetes Association. 1701 North Beauregard Street, Alexandria, VA 22311. (800) 232-3472. Website: www.diabetes.org. Summary: This article discusses the possible use of evening primrose to help halt or slow the progression of diabetic neuropathy and help prevent atherosclerosis. Evening primrose oil (EPO) contains essential fatty acids. It is about 85 percent linoleic acid by weight and about 10 percent gamma linoleic acid (GLA) by weight. Anti-inflammatory prostaglandins are made from GLA. In people who do not have diabetes, the body converts a portion of linoleic acid into GLA; however, in people who have diabetes, this conversion may be significantly impaired. Taking GLA orally via EPO capsules may help circumvent the decreased production of GLA from linoleic acid. One multicenter study demonstrated that daily use of GLA could improve the symptoms of diabetic neuropathy. In some cases, there can be a reversal of diabetic neuropathy symptoms. Results from the multicenter study also indicate that the best prevention of diabetic neuropathy seems to occur in patients who have the best control of their blood glucose levels. The dosage of EPO to help prevent neuropathy should be about six 500 milligram capsules taken with meals twice daily. EPO could also be a supplement to cholesterol lowering medications. Although there have been no controlled studies on the effect of EPO supplementation on the rate of heart attack in humans, one small study showed that a diet rich in EPO can cause a significant decrease in low density lipoproteins (LDLs). Several studies in animals have shown that EPO reduces the amount of LDLs and serum triglycerides in the blood. There appear to be few if any significant adverse effects of EPO in humans. The drawbacks to using EPO include its cost, which is generally about $50.00 for a 1 month supply, and its lack of regulation by the Food and Drug Administration.

Intensity and Amount of Physical Activity in Relation to Insulin Sensitivity: The Insulin Resistance Atherosclerosis Study Source: JAMA. Journal of American Medical Association. 279(9): 669-674. March 4, 1998. Summary: This article reports on a study designed to determine whether habitual, nonvigorous physical activity, as well as vigorous and overall activity, is associated with increased insulin sensitivity. The authors note that exercise training is associated with improved insulin sensitivity, but that the potential impact of habitual, nonvigorous activity is uncertain. Participants in this study included 1,467 men and women of African American, Hispanic, and non-Hispanic white ethnicity between the ages of 40 and 69. According to the results of the study, the correlation coefficient between insulin sensitivity and total estimated energy expenditure (EEE) was 0.14 when habitual physical activity was assessed by 1-year recall of activities. The association between vigorous and nonvigorous levels of EEE and insulin sensitivity was weakened after adjustment for the potential mediators, body mass index, and waist-to-hip ratio. Results were similar for subgroups of sex, ethnicity, and diabetes. The results of the study indicate that increased participation in nonvigorous, as well as overall and vigorous physical activity, was associated with significantly higher insulin sensitivity. These findings lend further support to current public health recommendations for increased moderate-intensity physical activity on most days. 6 tables. 40 references. (AA-M).

Association of Diabetes Mellitus With Coronary Atherosclerosis and Myocardial Lesions Source: American Journal of Epidemiology. 137(12): 1329-1340. June 15, 1993. Summary: This article reports on a study of the predictive relationship between diabetes and autopsy evidence of coronary atherosclerosis and myocardial lesions. Among 8,006 Japanese-American men examined at baseline in 1965-1968 as part of the Honolulu Heart Program, 7,591 were free of cardiovascular disease and 1,515 of these men died over a 17-year followup period. Diabetes status was defined using self-reported history and treatment at several examinations, as well as physician diagnoses during hospitalization between 1965 and 1984. An excess of coronary artery atherosclerosis was present among men with diabetes, but diminished to nonsignificant levels following adjustment for other cardiovascular risk factors. Even after adjustment for other risk factors, myocardial lesions occurred significantly more frequently among persons with diabetes than among nondiabetics. The authors conclude that the more adverse risk factor profile among men with diabetes appears to account for some of the observed excess of coronary atherosclerosis. However, diabetes was independently associated with myocardial lesions suggesting a role for nonatherosclerotic mechanisms, such as clotting abnormalities or microvascular disease, in accounting for the excess clinical heart disease found in persons with diabetes. 3 figures. 4 tables. 69 references.

Summary: This article reports on a study to compare increased insulin resistance and insulin secretion rates in nondiabetic African Americans and Hispanics compared with

nondiabetic non-Hispanic whites. Fasting and 2-hour postglucose load glucose and insulin levels, insulin-mediated glucose disposal (insulin sensitivity index), glucose effectiveness, and first-phase insulin response were determined in nondiabetic African Americans 9n=288), Hispanics (n=363) and non-Hispanic whites (n=435). African Americans and Hispanics were more obese than non-Hispanic whites. Both African Americans and Hispanics had higher fasting and 2 hour insulin concentrations and insulin response, but lower insulin mediated glucose disposal, than non-Hispanic whites. These results suggest that greater insulin resistance may be in large part responsible for the higher prevalence of noninsulin-dependent diabetes mellitus (NIDDM) in these minority groups. However, in Hispanics, the greater insulin resistance may be due to greater adiposity and other behavioral factors. 4 tables. 50 references. (AA-M). •

The mean and maximum intimal-medial thicknesses (IMT) of the carotid artery were assessed in 55 patients with type 1 diabetes (22 men and 33 women, aged 22.1 years, plus or minus 3.6 years; duration of diabetes 14.2 years plus or minus 5.7 years) and in 75 age-matched healthy nondiabetic subjects (28 men and 47 women). High-sensitive C-reactive protein hs-CRP) levels were also measured. The patients with type 1 diabetes had significantly higher hs-CRP levels as well as significantly higher mean IMT and max IMT than the nondiabetic subjects. Analyses for both diabetic and nondiabetic subjects as a single group showed that hs-CRP levels are independently correlated with the mean IMT and max IMT levels as well as with diastolic blood pressure, sex, and duration of diabetes. The authors conclude that hsCRP levels are elevated in young patients with type 1 diabetes, possibly corresponding with early-stage advanced carotid atherosclerosis. 1 figure. 4 tables. 28 references.

Atherosclerosis, Apolipoprotein E, and Prevalence of Dementia and Alzheimer's Disease in the Rotterdam Study Source: Lancet. 349: 151-154. January 18, 1997. Summary: This journal article describes a study of atherosclerosis, apolipoprotein E (apoE), and the prevalence of dementia and its major subtypes Alzheimer's disease (AD) and vascular dementia in a population-based sample of people aged 55 years and older from Rotterdam, the Netherlands. The study sample consisted of 284 patients with dementia (207 of whom had AD) and 1,698 controls without dementia. Carotid artery wall thickness and plaques assessed by ultrasonography and the ratio of ankle to brachial systolic pressure were used as measures of atherosclerosis, and the severity of atherosclerosis was scored on a scale of 0 (no atherosclerosis) to 3 (severe atherosclerosis). ApoE polymorphisms were assessed in 246 dementia patients and 928 controls. All measures of atherosclerosis were significantly associated with all dementia, AD, and vascular dementia. The frequencies of all dementia, AD, and vascular dementia increased substantially with atherosclerosis score. The odds ratio for AD in participants with severe atherosclerosis compared with those without atherosclerosis was 3.0. In participants with the apoE4 gene status and an atherosclerosis score of 2 or 3, the odds ratio for all dementia was 4.5, for AD was 3.9, and for vascular dementia was 19.8. The authors conclude that dementia and its major subtypes AD and vascular dementia are associated with atherosclerosis, and that this association is particularly strong in people with the apoE4 gene status. 1 figure, 3 tables, 29 references.

Inflammation-Mediated Rheumatic Diseases and Atherosclerosis Source: Annals of the Rheumatic Diseases. 59(5): 321-325. May 2000. Summary: This journal article provides health professionals with information on potential cardiovascular risk factors in systemic lupus erythematous (SLE) and rheumatoid arthritis (RA). Evidence substantiates the observation that young women with SLE or RA are developing atherosclerotic heart disease at higher rates than expected. Classic risk factors for cardiovascular disease in the general population such as hypercholesterolemia, diabetes mellitus, smoking, obesity, hypertension, and a sedentary lifestyle also appear to be important in SLE. Other risk factors for cardiovascular problems in SLE include older age at diagnosis and use or longer use of corticosteroids. Evidence also suggests that having SLE is an independent risk factor for cardiovascular disease. Research on the role of traditional cardiovascular risk factors in the development of atherosclerotic heart disease in RA has not been as extensive as it has been in SLE. The risk of atherosclerosis increases in otherwise healthy postmenopausal women, in part because of the drop in endogenous estrogen levels. However, in both SLE and RA, the abnormalities in sex hormone levels tend toward higher estrogen and lower androgen levels, or both. Although this suggests protection against atherosclerosis rather than increased susceptibility, the protective effect may be offset by the prothrombotic effects of estrogens, particularly in the presence of antiphospholipid antibodies. Another potential disease related or treatment related risk

11
factor in SLE and RA is raised serum homocysteine. The link between SLE and RA and atherosclerosis may be the increased expression of cellular adhesion molecules, the recruitment of inflammatory cells, and the lack of appropriate downregulation of proinflammatory processes. The article suggests that future prevention strategies for premature cardiovascular disease in SLE and RA should include a modification of traditional factors plus consideration of anti-inflammatory, immune modulatory, metabolic, and hormonal interventions. 66 references. •
Effect of Fenofibrate on Progression of Coronary-Artery Disease in Type 2 Diabetes: The Diabetes Atherosclerosis Intervention Study, a Randomised Study Source: Lancet. 357(9260): 905-910. March 24, 2001. Contact: Available from Lancet, Ltd. 655 Avenue of the Americas, New York, NY 10010. (212) 633-3800. Fax (212) 633-3850. Summary: This review article describes a study, the Diabetes Atherosclerosis Intervention Study (DAIS), that investigated the effect of fenofibrate on progression of coronary artery disease in type 2 diabetes. DAIS was conducted in 11 clinical centers in Canada, Finland, France, and Sweden. Of the 731 patients screened for inclusion in the study, 418 met the metabolic or cardiac entry criteria. These patients were randomly assigned 200 milligrams per day of micronized fenofibrate or placebo for at least 3 years. They were in good glycemic control, had mild lipoprotein abnormalities, and at least one visible coronary lesion. Half had no previous clinical coronary disease. Initial and final angiograms followed a standard protocol and were analyzed by a computer assisted quantitative approach. Missing data for the primary endpoints were imputed. Analyses were by intention to treat. The study found that total plasma cholesterol, high density lipoprotein (HDL) cholesterol, low density lipoprotein cholesterol, and triglyceride concentrations all changed significantly more from baseline in the 207 participants in the fenofibrate group than in the 211 participants in the placebo group. The fenofibrate group showed a significantly smaller increase in percentage diameter stenosis than the placebo group, a significantly smaller decrease in minimum lumen diameter, and a nonsignificantly smaller decrease in mean segment diameter. The trial was not powered to examine clinical endpoints, but there were fewer in the fenofibrate group than the placebo group. DAIS data suggest that treatment with fenofibrate reduces the angiographic progression of coronary artery disease in type 2 diabetes. This effect is related, at least partly, to the correction of lipoprotein abnormalities, even those previously judged not to need treatment. 4 figures. 2 tables. 30 references. (AA-M).

(800) 232-3472. Website: www.diabetes.org. Summary: This review article evaluates the relationship between insulin resistance and atherosclerosis in people who do not have diabetes. The main goal of the article is to review the risk factors for coronary heart disease (CHD) that occur with increased frequency in insulin resistant people, and to offer pathophysiological explanations for these relationships. The authors point out that CHD is the major cause of morbidity and mortality in people with type 2 diabetes, and that insulin resistance is present in most people who have type 2. Because insulin resistance is so common in people with type 2 diabetes, it is difficult to assess its role in CHD development. Topics include insulin resistance versus hyperinsulinemia; insulin resistance, compensatory hyperinsulinemia,

dyslipidemia, and CHD; the relationship between hypertriglyceridemia and other risk factors for CHD; and insulin resistance and/or compensatory hyperinsulinemia, hypertension, and CHD. The article notes that the ability of insulin to stimulate glucose uptake varies significantly from person to person. The authors conclude that, at the present time, it is difficult to know if insulin resistance is primarily responsible for accelerating the process of atherogenesis. They also conclude that resistance to insulinmediated glucose disposal and its consequences play a key role in the pathogenesis and clinical course of type 2 diabetes, hypertension, and CHD. 4 figures. 1 table. 90 references.

Website: www.rdhmag.com. Summary: Total health promotion includes education on reducing the risk factors for periodontal disease, as well as reducing the major controllable risk factors associated with cardiovascular diseases (CVD). Early prevention and intervention can significantly delay the onset of atherosclerosis ('hardening of the arteries') and cardiovascular disease which may result in disability and death from heart attack and stroke. This article brings dental hygienists up to date on the connections between periodontal disease and atherosclerosis. Topics include epidemiology and statistics about CVD and periodontal disease, definitions of atherosclerosis and how it develops, how periodontitis becomes a factor, blood cholesterol, physical inactivity, obesity, lifestyle and lifestyle modification, and the role of dental care providers, including dental hygienists. Dental hygienists can provide enough education so that patients can make informed decisions based on the risk factors identified during their medical history taking. Hygienists can also assist their patients in identifying the major controllable risk factors associated with CVD to establish risk of atherosclerosis and cardiovascular disease and offer suggestions regarding the necessary lifestyle changes to reduce those risks.

Incident Type 2 Diabetes Mellitus in African American and White Adults: The Atherosclerosis Risk in Communities Study Source: JAMA. 283(17):2253-2259. May 3, 2000. Summary: Using data collected between 1986 and 1989, this study compares the risk of diabetes in African American and white adults between the ages of 45 and 64 and attempts to find explanations for the differences. The authors conclude that middle-aged African Americans are at greater risk of developing type 2 diabetes than middle-aged whites, and have higher blood pressure prior to the development of diabetes. In African American women, but not in men, almost half of this excess risk might be related to modifiable factors, such as overweight.

Project Title: ACCELERATED PREVALENCE/FACTORS
ATHEROSCLEROSIS
IN
SLE--
Principal Investigator & Institution: Roman, Mary J.; Professor; Medicine; Weill Medical College of Cornell Univ New York, Ny 10021 Timing: Fiscal Year 2001; Project Start 01-APR-1999; Project End 31-MAR-2004 Summary: (Adapted from the Investigator's Abstract) Autopsy and observational data suggest that systemic lupus erythematosus (SLE) is associated with premature atherosclerosis and myocardial infarction; however, clinical studies have reported widely varying event rates, and the prevalence of underlying disease (atherosclerosis and myocardial disease) in SLE patient samples and its relation to that in a control population are unknown. The prevailing hypothesis has been that accelerated atherosclerosis is attributable to an increased frequency of conventional risk factors in SLE patients such as hypertension, hyperlipidemia and obesity, all of which may be provoked or potentiated by therapeutic use of corticosteroids. Alternatively, antiphospholipid antibody (APLA), present in about 20% of the SLE patients, may result in vascular occlusions due to abnormal clotting rather than atherosclerosis; however, data are accumulating that suggest that the inflammatory process per se may be important in the initiation and progression of atherosclerosis. Pilot data for this study indicate that underlying non-invasively- detected atherosclerosis is several-fold more common in patients with SLE in comparison to matched control subjects. Furthermore, left ventricular mass, a marker for and mediator of enhanced cardiovascular morbidity and mortality, is strikingly higher in SLE patients, even after adjustment for differences in body size. Neither of these observations is explained by standard risk factors. Thus, the goals of this project are to: 1) establish the prevalence of atherosclerosis and myocardial disease in an unselected population of SLE patients; 2) compare findings to those in a control population; 3) determine whether the excess prevalence of pre-clinical cardiovascular disease is independent of known cardiovascular risk factors and is additionally related to markers of inflammation and immune system activation; and 4) determine whether atherosclerosis and LV hypertrophy progress more rapidly in SLE patients than in control subjects. Based on preliminary data, the investigators hypothesize that pre-clinical disease will be more common in SLE and will not be fully explained by conventional risk factors for atherosclerosis or thrombosis. They further hypothesize that basic aspects of the inflammatory process (to be partially investigated 2

Project Title: ANDROGENS AND SUBCLINICAL ATHEROSCLEROSIS IN YOUNG WOMEN Principal Investigator & Institution: Siscovick, David S.; Medicine; University of Washington Seattle, Wa 98195 Timing: Fiscal Year 2001; Project Start 30-SEP-2001; Project End 31-JUL-2004 Summary: (provided by applicant): This revised application represents an ancillary study to the Coronary Artery Risk Development in Young Adults (CARDIA) Study, a large cohort study supported by the NHLBI. Several studies have demonstrated crosssectional associations of hyperandrogenism, the primary biochemical feature of clinically-diagnosed polycystic ovarian syndrome (PCOS), with coronary risk factors and atherosclerosis. We propose to examine whether serum androgens, measured earlier in life, and variation in genes related to androgen synthesis, metabolism, and signaling are associated with early-onset subclinical coronary atherosclerosis in young adult women from the community. Additionally, we will examine whether the clinical features of PCOS are associated with subclinical coronary atherosclerosis in young adult women, after taking into account serum androgens. CARDIA provides a unique platform to address these questions; and, the proposed ancillary study will add the laboratory and clinical measurements to CARDIA needed to examine these questions. In the prospective component of the proposed study, we will examine the associations of serum androgens and genetic polymorphisms and haplotypes in ten candidate genes with the presence of coronary artery calcium (CAC) by CT. Androgen and genotyping measures will be made using stored serum and DNA samples collected from 1550 women 5 and 13 years prior to the assessment of CAC at age 33 to 45 years. In the crosssectional component, we will use information collected at a proposed ancillary study visit in Year 16 to examine the associations of the clinical features of PCOS, including the presence of polycystic ovaries detected using trans-vaginal ultrasound, menstrual irregularities, infertility, and hirsutism, with the presence of CAC at Year 15 (n= 1200). Secondarily, we will determine whether longitudinal changes in obesity, physical inactivity, and insulin levels influence the prospective associations of serum androgens and genetic variants in candidate genes with subclinical coronary atherosclerosis. In short, the proposed study addresses a potentially important and relatively unexplored area of investigation related to women's cardiovascular health.

Project Title: ANTIOXIDANT AND ANTIINFLAMMATORY MECHANISMS OF HDL Principal Investigator & Institution: Rader, Daniel J.; Director, Preventive Cardiology; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 01-MAY-2002; Project End 31-MAR-2007 Summary: (provided by the applicant): High density lipoproteins (HDL) their major protein apoA-I directly protect against atherosclerosis cardiovascular disease, but the mechanisms are not well understood. In addition to its role in reverse cholesterol transport, HDL may have other properties that contribute to its anti-atherogenic effects. We hypothesize that HDL has anti oxidant and anti-inflammatory effects that are relevant and operative in vivo and are important components of the atheroprotective

15
effects of HDL. The focus of this proposal is to test this hypothesis using relevant in vivo models in mice and in humans. We will utilize approaches as described in detail in Project 1 (oxidatively modified lipids), Project 2 (nitrated proteins), Project 3 (oxidatively modified extracellular matrix) and Project 4 (oxidative DNA adducts) of this SCOR proposal, to study novel mechanisms by which HDL inhibits atherogenesis. Specific Aim 1: To test the hypothesis that HDL inhibits oxidation of lipids (lipoprotein and plasma membrane), nitration of proteins, oxidative fragmentation of extracellular matrix, and DNA in vitro and to determine the mechanism for these anti-oxidant effects of HDL. Specific Aim 2: To use mouse models of atherosclerosis to determine the effect of both apoA-I deficiency and apoA-1 overexpression on markers of oxidative stress and inflammation in vivo and the relationship to atherosclerosis. Specifically, we will test: 1) that apoA-1 deficiency accelerates the age-related progression of markers of oxidant stress, vascular inflammation, and atherosclerosis; 2) that apoA-I overexpression reduces in vivo oxidant stress and vascular inflammation; 3) that HDL?s effect in increasing prostacyclin is an important in vivo by determining the effect of overexpression of apoA-I on atherosclerosis in the prostacyclin receptor (IP) knockout mouse; and 4) that HDL inhibits atherosclerosis even in the setting of impaired reverse cholesterol transport by determining the effect of apoA-I overexpression on atherosclerosis in SR-BI knockout mice. Specific Aim 3: A prospective observational study will be performed in asymptomatic persons with high HDL-C levels and two comparison groups: individuals with average HDL-C levels and individuals with low HDL-C levels. Baseline markers of oxidant stress and inflammation will be compared among the three groups. In addition, two quantitative measures of subclinical atherosclerosis, carotid intimal-medial thickness (IMT) and coronary artery calcification (CAC) will be determined at baseline. These baseline measures will be repeated at two years. In the three HDL strata, baseline levels of oxidant stress and inflammation will be examined as predictors of progression of atherosclerosis. The experiments proposed will generate substantial insight into the mechanisms by which HDL protects against atherosclerosis, information crucial to the rational development of novel HDL-raising strategies.

Project Title: APOLIPOPROTEIN GENES AND ATHEROGENESIS IN ANIMALS Principal Investigator & Institution: Maeda, Nobuyo; Professor; Pathology and Lab Medicine; University of North Carolina Chapel Hill Office of Sponsored Research Chapel Hill, Nc 27599 Timing: Fiscal Year 2001; Project Start 01-APR-1989; Project End 31-MAR-2003 Summary: The long term goal of our research is to develop a deep understanding of the genetic factors underlying atherosclerosis, using mice genetically altered by targeting. The upcoming grant period will take advantage of the predictable development of atherosclerosis in our apolipoprotein E-deficient mice to explore how the atherogenic process is affected by mutations in genes other than those directly involved in lipid metabolism. The genes chosen for study in our three specific aims are each individually important for maintaining vascular health and eanh is a likely candidates for altering the vascular response to elevated levels of plasma lipoproteins. In addition, changes in these genes are likely to make current mouse models of atherosclerosis closer to the human condition. Specific aim 1: We will generate a genetic absence of ascorbic acid (vitamin C) synthesis in mice, by disrupting the mouse L-gulono-gamma- lactone oxidase gene, which humans lost during the evolution. We will combine this with a genetic lack of apoE to test the importance of this dietary antioxidant in the prevention

of atherosclerosis and in stabilizing atherosclerotic plaques. Specific aim 2: We will test the importance of monocyte recruitment for early lesion development by generating apoE null mice carrying 0, 1, 2, 3, or 4 copies of the chemokine receptor CCR2 gene, coding for the primary receptor for the chemokine MCP-1 (monocyte chemoattractant protein 1). Specific aim 3: We will test the hypothesis that mutations causing elevation in the blood pressures of animals will influence the development, distribution, and the stability of atherosclerotic plaques by combining apoE deficiency with mutations in genes coding for angiotensinogen, endothelial nitric oxide synthase or natriuretic peptide receptor A.

Project Title: ARGINASE AND NITRIC OXIDE IN ATHEROSCLEROSIS Principal Investigator & Institution: Ignarro, Louis J.; Professor; Molecular & Med Pharmacology; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2001; Project Start 06-MAR-2001; Project End 31-JAN-2005 Summary: (Verbatim from the application): In the response-to-injury hypothesis of atherosclerosis, numerous factors are involved in atherosclerotic lesions resulting from local injury, including impairment of the arginine-NO pathway. NO and its precursor intermediate, N-hydroxyarginine (NOHA), are potent inhibitors of cell proliferation that interfere with the arginine-polyamine pathway. Deficient production of NOHA + NO may accelerate proliferation of vascular smooth muscle, macrophages and other cells. Arginase is a high turnover enzyme that utilizes arginine to form ornithine + urea. Ornithine is a precursor for polyamines required for cell growth. Elevated arginase activity causes increased conversion of arginine to polyamines at the expense of decreased conversion of arginine to NOHA + NO due to limiting arginine availability. Decreased production of NOHA + NO further amplifies polyamine production due to decreased negative feedback on the arginine-polyamine pathway. Increased arginase expression is characteristic of atherosclerotic lesions and administration of arginase inhibitors to animals with atherosclerosis decreases disease progression. The central hypothesis that drives this proposal is that atherosclerosis is associated with the induction of arginase, leading to increased polyamine production that is further enhanced by diminished production 01 NOHA + NO. The principal objective of the proposed research is to determine whether the increased cell proliferation in atherosclerosis is attributed to increased arginase activity and consequent increased polyamine production coupled to decreased NOHA and NO production. The rationale for this objective is based on our previous findings that NOHA and NO inhibit cell growth by interfering with two sequential steps in the arginine-polyamine pathway. Two specific aims are proposed to address the objective: (a) to elucidate the mechanisms by which increased arginase activity leads to increased cell proliferation, and (b) to determine the effectiveness and mechanisms by which arginase inhibitors slow the progression of atherosclerosis in animal models of atherosclerosis. The feasibility of this approach is borne out by the extensive preliminary data that support the central hypothesis. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Studies
17
Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-JUL-2004 Summary: (provided by applicant): Human epidemiological studies have shown an association between periodontal and vascular diseases. In parallel, the inflammatory and potentially infectious- nature of atherosclerosis is gaining recognition, suggesting a potential link between infectious diseases, such as periodontitis, and atherosclerosis. However, the effect of periodontal pathogens in atherosclerosis has not been clearly established. The goal of this proposal is to investigate the contribution of oral pathogens to the development of atherosclerotic lesions in a murine model. The apolipoprotein E knockout mouse (ApoE) prone to atherosclerosis will be infected with one recognized human periodontal pathogen in an established model of chronic and localized infection (subcutaneous chamber). Experimental conditions (including power calculations) have been optimized in preliminary studies using this model of infection-enhanced atherosclerosis. Aim 1 will focus on answering the question "could periodontal pathogens contribute to the development of atherosclerotic lesion?" Localized infection will be established by intra-chamber injection of live bacterial cultures of Porphyromonas gingivalis in pre-immunized ApoE mice. Controls will receive medium alone. Two strains of P. gingivalis with varying virulence properties will be tested for their ability to induce an increase in the aorta atheroma lesion size (evaluated at sacrifice by histomorphometry). In parallel, the inflammatory response will be monitored by measuring levels of serum inflammatory cytokines (IL-6 and IL-1 by ELISA) and acute phase proteins (Serum Amyloid A by ELISA). Interaction analyses will be performed to test our hypothesis that infection with P. gingivalis contributes to the development of atherosclerotic lesion by triggering an inflammatory and acute phase response. Aim 2 will address the question "what specific virulence trait(s) expressed by P. gingivalis contribute to the development of atherosclerotic lesion?" Mutants of P. gingivalis for specific virulence factors (Pep0 and FimA,) will be prepared in the most atherogenic strain identified in aim 1 in laboratories. These mutants will be tested in our murine model in regard to atheroma lesion size. In addition, presence of P. gingivalis DNA will be investigated by PCR in descending aorta and liver samples, and serum anti-P. gingivalis antibody levels will be measured by ELISA, to test our hypothesis that specific virulence traits confer to P. gingivalis the ability to evade the host antibody defense system, and reside in organs such as the aorta and the liver. Results from these studies will help in the identification of new targets for atherosclerosis and vascular disease therapies. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

This proposal builds on the population-based studies of aging in Beaver Dam, WI: The Beaver Dam Eye Study (EY06594) and the Epidemiology of Hearing Loss Study (AG11099). Participants with incident early age-related maculopathy or incident latestage age-related maculopathy as determined from grading of standardized photographs taken at two examinations five years apart will be eligible as cases for this study. Participants without age-related maculopathy at the time of the 1 0-yr follow-up

eye examination will be eligible as controls. Incident early cases will be frequencymatched by age and gender to controls using a two-to-one ratio of controls to cases. Incident late age-related maculopathy cases will be frequency-matched to controls by age and gender using a three-to-one ratio of controls to cases. Based on expected 5-yr incidence rates and participation rates in both studies, we estimate that a total of 189 cases with incident early age-related maculopathy and 378 controls and 34 cases with incident late age-related maculopathy and 102 controls will be included in this study. Generalized atherosclerosis will be measured by intima-medial thickness and the presence of plaque in the carotid arteries. Stored videotapes of B mode ultrasound scans of the carotid arteries were obtained as of the Epidemiology of Hearing Loss Study, using a modification of the Atherosclerosis Risk in Communities Study protocol. These scans will be read, and measurements of the intima-medial thickness made, using the Atherosclerosis Risk in Communities ultrasound reading protocol. Age-related maculopathy is well-recognized to be the leading cause of blindness among older adults and a significant public health problem for older adults. As yet there is no way to prevent or effectively treat this disorder. This study will provide important epidemiologic information about the role of atherosclerosis in the etiology of agerelated maculopathy. It takes advantage of an unique opportunity to evaluate this association by utilizing an existing population-based cohort with standardized assessments of the incidence of age-related maculopathy and standardized carotid artery ultrasound scans.

Project Title: ATHEROSCLEROSIS PREVENTION IN MICE BY MUTANT APO A-1 Principal Investigator & Institution: Getz, Godfrey S.; Professor and Chair; Pathology; University of Chicago 5801 S Ellis Ave Chicago, Il 60637 Timing: Fiscal Year 2001; Project Start 01-FEB-1997; Project End 31-JAN-2003 Summary: (Adapted from Investigator's Abstract): An inverse correlation between HDL level and protection against atherosclerosis has emerged from human population studies and the study of transgenic mice. Human HDL is heterogeneous, consisting of two major species, HDL2 and HDL3. In most human population studies, variations in the level of HDL2 have been negatively correlated with atherosclerosis. ApoA-I(Milano) appears to be an exception to the generalization in that modest levels of HDL in these subjects are nevertheless protective, in spite of the fact that HDL3 particles are prominent in these individuals. In this proposal, we will examine the ability of murine and human apoA-Iand apoA-I variants that generate different levels of HDL subclasses to protect against the development of different stages of atherosclerosis (fatty streak lesions and progression to fibroproliferative lesions) and to promote regression of lesions that spontaneously develop in apoE deficient mice. ApoA-I will be introduced into these mice via adenoviral vectors which will allow for the timed expression of apoA-I, as well as manipulation of the amount of protein by varying the dose of virus injected. For long term expression, mice that are deficient in RAG2 as well as apoE are available. Murine and human apoA-I will be compared. Human apoA-I will be expressed in SMC or macrophages (transgenic mice) to assess its impact on atherosclerosis. Other variants will focus on the murine/human chimeric apoA-I and apoA-I(Milano) and related mutants, the latter to assess the importance of heterodimer formation in protecting against atherosclerosis. The influence of human apoA-I and apoA-I variants on atherosclerosis, HDL subclass levels, the ability to stimulate cholesterol efflux and the antioxidant properties of the HDL will be assessed, to attempt correlations among these properties of apoA-I. The Specific Aims are to: 1) determine

Project Title: ATHEROSCLEROSIS, DIABETES AND LPL Principal Investigator & Institution: Semenkovich, Clay F.; Professor; Internal Medicine; Washington University Lindell and Skinker Blvd St. Louis, Mo 63130 Timing: Fiscal Year 2001; Project Start 01-APR-1998; Project End 31-MAR-2002 Summary: Adapted from applicant's abstract): Atherosclerosis is common in humans with diabetes. The underlying mechanisms are not completely clear. Common genetic conditions such as heterozygous LPL deficiency could potentiall be involved. However, the exact role of LPL and atherosclerosis, especially in diabetic patients is uncertain. The long term objective of the application is to understand the mechanisms of premature atherosclerosis in diabetic patients The applicants have generated a mouse with heterozygous LPL deficiency. These heterozygous mice have been crossed with low density lipoprotein receptor knockout mice to generate double knockout mice. The investigators have demonstrated the feasibility of diet-induced atherosclerosis in these models, as well as the production of experimental diabetes. The studies proposed will test the hypothesis that genetic heterozygous LPL deficiency promotes atherosclerosis in diabetes. The application has the following Specific Aims: To determine the effects of the LPL deficient heterozygous state alone and in combination with the LDL receptor deficient phenotype on atherosclerosis in mice with streptozotocin-induced diabetes used as a model for Type-I diabetes. To define how the LPL deficient heterozygous state interacts with streptozotocin-induced diabetes to affect vascular wall gene expression and lipoprotein biology. To determine the effects of the LPL heterozygous deficient state alone and in combination with the LDL receptor knockout phenotype on atherosclerosis in mic with dietary-induced diabetes used as a model for Type-II diabetes. To define how the LPL heterozygous deficient state interacts with this model of diabetes to affect vascular wall gene expression and lipoprotein biology.

Project Title: BIOLOGY OF 12-LIPOXYGENASE ISOZYMES Principal Investigator & Institution: Funk, Colin D.; Professor of Pharmacology; Pharmacology; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2001; Project Start 01-FEB-2000; Project End 31-JAN-2004 Summary: Atherosclerosis, chronic inflammatory process progressing from fatty lesions to fibrous and unstable plaques, is the major underlying factor in most cases of coronary heart disease. Clinical disease as a result of atherosclerotic disease remains as the leading determinant for the extensive mortality and morbidity. and exorbitant health care costs in our society. The "LDL oxidation" hypothesis has gained general acceptance as a leading player in atherogenesis and it is recognized that oxidized LDL exhibits

many pro-atherogenic properties. properties. The factors that initiate LDL, oxidating in vivo are poorly understood. However, circumstantial evidence has placed the 12/15lipoxygenase in the context of atherosclerosis. Thus, in the first specific aim, the role of 12/15- lipoxygenase in mouse models of atherosclerosis (apoB editing catalytic polypeptide-1 (apobec-1)/LDL-receptor deficient and apoE deficient) will be assessed by quantitating lesion development throughout the aorta by the "en face" method using appropriately crossbred 12/15-lipoxygenase deficient mice. The combined effects of the anti-oxidant vitamin E with 12/15-lipooxygenase deficiency will also be examined. Total cholesterol, triglycerides, lipoprotein profiles and oxidative stress markers known as isoprostanes will be measured and correlated with lesion development. If specific 12/15-lipoxygenase inhibitors are ultimately to be used in atherosclerotic disease management they will need to be effective in limiting, or causing regression of, preexisting lesion. By using an inducible 12/15-lipoxygenase gene disruption strategy in mice with atherosclerosis at various stages this important matter will be addressed. In specific aim 2, the subset of macrophages expressing 12/15- lipoxygenase will be characterized and purified. The effects of lipid loading and factors regulating 12/15lipoxygenase gene expression will be determined. In specific aim 3, the novel 12(R)lipoxygenase will be characterized and its relevance to atherosclerosis and LDL oxidation discerned.

Project Title: CD1-RESTRICTED T CELL RESPONSE IN ATHEROSCLEROSIS Principal Investigator & Institution: Geng, Yong J.; Assistant Professor; Medicine; University of Texas Hlth Sci Ctr Houston Box 20036 Houston, Tx 77225 Timing: Fiscal Year 2001; Project Start 30-SEP-2001; Project End 31-JUL-2005 Summary: (provided by applicant): The cluster of differentiation I (CD1) proteins represent a new class of antigen-presenting molecules, which structurally resemble MHC class I antigens and may restrict certain T lymphocyte responses to lipid antigens. There are two groups of CD1 molecules encoded by five CD1 genes (CD1a, b, c, d and e). Atherosclerotic lesions contain numerous T cells and CD1-positive macrophages and dendritic cells in addition to chemically modified lipids (e.g., cholesterol oxides or oxysterols and oxidized phospholipids) present in oxidized lipoproteins, raising the possibility that CD1-restricted T cells may exist in the lesions and respond to atherogenic lipid antigens presented by local macrophages and dendritic cells. The specific aims of this proposal are to determine (1) the CD1 isotype expression and CD1restricted T cell response to lipid components of oxidized lipoproteins in atherosclerosis; (2) the association of an CD1 mutation or polymorphism with altered vascular autoimmunity in patients with SLE and atherosclerosis; (3) the cytokine production and pro-apoptotic function of CD1d-restricted NK T cells that are reactive to lipid antigens; and (4) the impact of knocking out CD1d gene on the T cell responses to lipid antigens and the development of atherosclerosis caused by apolipoprotein-E deficiency. The experimental procedures involve the analysis of T cell cytokine production and antigen receptor profiles, the evaluation of T cell response to CD1- lipid complexes, the assessment of genomic DNA sequences for CD1 genes, and the histopathological characterization of atherosclerotic lesions in the CD1/apolipoproteinE double knockout mice recently established in our lab. Accomplishment of this project is anticipated to generate valuable information that help understand the immune mechanisms underlying vascular injury during atherogenesis.

Principal Investigator & Institution: Bostrom, Kristina I.; Assistant Professor of Medicine; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2008 Summary: This Project is focused on understanding the molecular mechanisms involved in vascular calcification and osteoporosis. Matrix GLA protein (MGP) was strongly implicated in the pathogenesis of vascular calcification when an MGP knockout mouse was found to have extensive vascular calcification. Based on this mouse model, MGP might be thought to be an inhibitory factor in vascular calcification. However, in calcified lesions of mice that have a normal MGP gene and in human lesions, MGP expression is postively correlated with the degree of lesion calcification. During the current grant period we demonstrated that MGP regulates bone morphogenetic protein (BMP-2), During the next grant period we will determine the molecular basis for the regulatory role of MGP in the artery wall and its interaction with BMP-2. Other work from this Project during the current grant period provided important clues as to why many patients with progressive vascular calcification also have progressive osteoporosis. Oxidized lipids were shown to promote calcification of calcifying vascular cells (CVC) but inhibited the osteoblastic differentiation and mineralization of marrow stromal cells that are the precursors to mature bone osteoblasts. This was true whether the oxidized lipids were added in vitro or were produced by feeding atherosclerosis suceptible C57BL/6J (BL6) mice an atherogenic diet. These oxidized lipids were also shown to promote osteoclastogenesis and osteoclast activation in vitro. In vivo, feeding an atherogenic diet to atherosclerosis susceptible BL6 mice produced a dramatic reduction in bone mineral density and bone mineral content. Feeding an atherogenic diet to atherosclerosis resistant C3H/HeJ mice causes the same degree of hyperlipidemia as in BL6 mice, but there was no significant reduction in either bone mineral density or bone mineral content in the C3H/HeJ mice. In the next grant period we propose to determine the molecular mechanisms for these observations and we will determine if high density lipoproteins (HDL), components of HDL, and mimetics of HDL will protect against bone loss in mouse models of atherosclerosis. These studies may identify potential new therapeutic targets in vascular calcification and osteoporosis. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: CHARACTERIZATION OF FORTILIN, A NOVEL ANTI-P53 PROTEIN Principal Investigator & Institution: Fujise, Kenichi; None; University of Texas Hlth Sci Ctr Houston Box 20036 Houston, Tx 77225 Timing: Fiscal Year 2001; Project Start 30-SEP-2001; Project End 31-JUL-2005 Summary: (provided by the applicant): Atherosclerosis is the leading cause of coronary artery disease, peripheral vascular disease and cerebrovascular disease in this country, afflicting millions of Americans. The pathogenesis of atherosclerosis is complex, yet dysregulated proliferation of smooth muscle cells is implicated as an important proponent. A genetic study using p53 knockout mice suggested that he presence of functional 053 is preventive against atherosclerosis in a hyperlipidemic environment. In addition, studies have indicated that the presence of p53 inhibitors, such as Mdm-2 and IE84, accelerates atherosclerosis. Our laboratory identified a new p53 inhibitor and designated it as fortilin. Characterization of fortilin in our laboratory so far showed: (1) The peptide sequence of fortilin is highly conserved among different species. (2) The

message of fortilin is resent in all normal human tissues while its expression is greater in cancerous cell lines. (3) Fortiin expression is more prominent in malignant than I benign tissue. (4) Fortilin binds p53. (5) The overexpression prevents of fortilin prevents cells from undergoing etoposide-induced apoptosis. (6) The over expression of fortilin prevents cells from undergoing apoptosis induced by the expression of p53. (7) The overexpression of fortilin inhibits p53-mediated transactivation of BAX, a pro-apoptotic molecule. (8) The expression of fortilin is up regulated in atheroma. There are three major Specific Aims proposed to further characterize fortilin and the fortilin-p53 interaction: Aim 1: To define the region of fortilin that interacts with p53 and other molecules. We will first determine which domain of fortilin participates in p53 binding by generating and evaluating various deletion mutants for their ability to interact with fortilin (Aim1.1). We will then identify the region of that fortilin domain that is required for the interaction with p53 (Aim1.2). Finally, we will establish whether fortilin is covalently modified by sentrin and other ubiquitin-like molecules (Aim 1.3). Aim 2: To characterize the region of p53 that interacts with fortilin and other molecules. In this major aim, we determine which domain (Aim 2.1) and region (Aim 2.2) of p53 participates in fortilin binding, using deletion and point mutants, respectively. We will then evaluate whether the fortilin-binding region of p53 is required for p53 to interact with Mdm2, Mdm-X and BRCA2, p53 binding and inhibitory molecules (Aim 2.3). Aim 3: To investigate the regulatory role of fortilin-p53 interaction in apoptosis. We will determine whether fortilin inhibits p53-mediatd apoptosis (Aim3.1), p53-mediated transactivation of Bax (Aim 3.2) and p53 binding to the Bas-responsive element (Aim 3.3) THROUGH ITS DIRECT binding of p53. Knowledge gained I this proposal will enable us to have a solid foundation for the future intervention of human atherosclerosis. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: CHEMOKINE RECEPTOR ANTAGONISTS IN INFLAMMATORY DISEASE Principal Investigator & Institution: Shahrara, Shiva; Medicine; Northwestern University Office of Sponsored Programs Chicago, Il 60611 Timing: Fiscal Year 2003; Project Start 01-FEB-2003; Project End 31-JAN-2008 Summary: (provided by applicant): There are many similarities in inflammatory responses observed in atherosclerosis and rheumatoid arthritis (RA). Chemokines and their receptors are important in both diseases. The long-term objectives of this application are to study the clinical and biological effects of C-C chemokine receptor 2 (CCR2) and CCR1/CCR5 antagonists in rodent arthritis. Furthermore we plan to determine the effect of key proinflammatory (TNF-alpha and IL-1beta) and Th1 promoting (IL-12 and IL-18) cytokines on CCR5 and CCR2 post-receptor signaling events in the 2D61L-12 T cell line and endothelial cells in the presence of CCR5/CCR2 antagonists. Using CCR2/CCR5 antagonists in a model of inflammatory disease (RA) in vivo in addition to the knowledge acquired from studying the mechanism of proinflammatory cytokines effects on CCR2/CCR5 signaling pathways in vitro will help us understand and design more efficient in vivo studies in both RA and atherosclerosis. Several studies have used antagonists, binding proteins and antisense sequences to target proinflammatory cytokines, including TNF-alpha (antagonist; Etanercept), IL-18 (binding protein) and chemokine receptors CCR2/CCR5 (antagonists, antibodies and gene knockouts) in hope of mitigating the inflammatory reaction in atherosclerosis and RA. In order to investigate the effect of IL-12 and IL-18 on CCR5 and the effect of TNFalpha, IL-1beta and IL-8 on CCR2 downstream signaling pathways, we will

immunoprecipitate CC chemokine receptors in cytokine treated cells and detect associated pathways by Western blot analysis. The purpose of using CCR antagonists is to validate that the cytokines exert their effect through these receptors. Additionally we will use CCR2/CCR5 antagonists in an in vivo inflammatory model of RA (rat adjuvant induced arthritis (AIA)) to examine their ability to decrease the severity and delay the onset of the disease. For this purpose we will determine the progression of indicators of inflammation, such as arthritis index, joint circumference, paw volume, joint count, arthritis severity, cell type recruitment and markers of bone destruction. Achieving these goals may give us valuable information in regard to molecular inflammatory mechanisms involved in atherosclerosis and RA.

Principal Investigator & Institution: Byrne, Gerald I.; Professor & Chairman; Medical Microbiol & Immunology; University of Wisconsin Madison 750 University Ave Madison, Wi 53706 Timing: Fiscal Year 2001; Project Start 15-FEB-1999; Project End 31-JAN-2004 Summary: (Adapted from the Applicant's Abstract): Chlamydia pneumoniae, a causative agent in human community acquired pneumonia, also has been implicated in a variety of sequelae associated with chronic disease and re-exposure to the organism. One important sequel associated with C. pneumoniae infection is the development of atherosclerotic lesions that define the pathology of cardiovascular disease in people. Cardiovascular disease due to atherogenic processes is a major health problem in most of the world, accounting for about 50% of all deaths. It is clear that vascular injury is crucial in the development and progression of atherosclerosis and that this injury can result from a variety of causes, including infection. Several lines of evidence support the hypothesis that C. pneumoniae infection is linked to the development of atherosclerosis. Initially, seroepidemiological evidence was generated to establish a relationship between C. pneumoniae and cardiovascular disease. Subsequently, evidence for the presence of the organism in atherosclerotic lesions was obtained using either direct antigen detection methods or probes specific for C. pneumoniae nucleic acids. In addition, the organism has been isolated from an aortic lesion and grown in cell culture. Finally, two pilot secondary prevention antibiotic treatment trials have provided evidence to suggest that treatment of C. pneumoniae in individuals with coronary heart disease significantly reduces cardiac events in treated versus placebo administered populations. Thus, although the association of C. pneumoniae and atherosclerosis is well-established, existing data do not prove an etiology or pathogenic role for the organism in disease, although both rabbit and murine animal models have been developed to determine if C. pneumoniae is causally associated with development or progression of atherosclerotic lesions in vivo. Activation and modification of mononuclear phagocyte function is associated with atherosclerotic lesion development. Characteristic changes include development of cholesteryl ester-laden monocytes (foam cells) and oxidation of lipids to form tissue-damaging derivatives. The hypothesis to be tested here is that infection of human monocytes, monocyte-derived macrophages or murine monocyte cell lines with C. pneumoniae results in changes in macrophage morphology and function that are consistent with a role for C. pneumoniae in the pathogenesis of atherosclerosis. This hypothesis will be tested by determining if C. pneumoniae causes mononuclear phagocytes to form foam cells in the presence of low density lipoprotein (LDL) or other cholesterol-containing serum lipoprotein complexes.

Studies also will be conducted to determine if C. pneumoniae contributes to the oxidative modification of LDL and molecular characterization of C. pneumoniae antigens involved in these processes will be identified. Finally, a murine model will be developed to provide in vivo correlates to cell culture observations. Results will help establish links between C. pneumoniae infection and the atherosclerotic disease process. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: CLONING AND CHARACTERIZATION OF ATH8 Principal Investigator & Institution: Paigen, Beverly J.; Senior Staff Scientist; Jackson Laboratory 600 Main St Bar Harbor, Me 04609 Timing: Fiscal Year 2001; Project Start 01-AUG-1999; Project End 31-JUL-2003 Summary: The mouse model of atherosclerosis can be used to identify novel genes that affect atherosclerosis susceptibility. Non-lipid risk factors are important in heart disease but it is difficult to identify the genes that underlie such factors. One approach to identifying such factors to clone the genes underlying atherosclerosis differences between mouse strains that can not be explained by the lipid profiles. Ath8 is such a gene; it is the major determinant of the atherosclerosis susceptibility difference between inbred strains NZB/BINJ (NZB) and SM/J (SM). Although strains NZB and SM differ in HDL-cholesterol and VLDL-LDL cholesterol, Ath8 affects atherosclerosis independently of these lipoprotein differences. The identify of the Ath8 gene product may therefore provide insights into the non-lipid factors that affect heart disease risk. Ath8 was mapped recent in our laboratory using quantitative trait loci mapping techniques. We propose to positionally clone Ath8. Because Ath8 was mapped in a relatively small cross, the chromosomal region containing the gene is large, approximately 28 cM. Therefore, the first step in cloning this gene will be to narrow the region by three sequential mouse crosses. Once the region is sufficiently narrowed, a DNA contig will be constructed and a complete transcript map of all genes in the region obtained. Transcripts will be evaluated by expression patter and function, if known. Candidate genes will be tested by sequence the cDNA from both strains or by expression differences between the strains. Finally, the most compelling candidate gene will be tested by transgenic rescue of the phenotype or construction of a knockout with a resulting change in atherosclerosis phenotype.

Project Title: COMPLEMENT, CARDIOVASCULAR DISEASE, AND SLE Principal Investigator & Institution: Ahearn, Joseph M.; Associate Professor; Medicine; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 31-MAY-2007 Summary: (provided by applicant): Inflammation is now recognized as a critical process in the development and rupture of atherosclerotic plaques, and in the morbidity and mortality that result from cardiovascular disease. Recent studies have also suggested that this process may be accelerated and exaggerated in patients with systemic lupus erythematosus. We have recently established a research program focused on vascular biology and pathology, with a focus on lupus as a model of accelerated atherosclerosis. The stimulus for these investigations was a recent surprising observation by Manzi and colleagues who demonstrated a strong linear association between elevated serum levels of C3 and C4 and aortic stiffness in premenopausal women with SLE. Whereas decreased serum levels of C3 and C4 have traditionally been used to monitor disease activity in patients with SLE, association of elevated serum levels of serum complement

25
components with any disease process is unprecedented. This observation led us to investigate the potential role(s) for complement C3 and C4 in the immunopathogenesis of cardiovascular disease in SLE. Vascular imaging studies led to several intriguing and unexpected observations that will be further explored here. First, we discovered that complement components C3 and C4 are present in several distinct patterns within the arterial walls of both humans and mice. Specifically, proteolytic fragments of C3 and C4 co-localize with, and may be covalently bound to, elastin within the arterial wall. This entirely unexpected observation suggested that complement deposition within the arterial wall may increase vascular stiffness, an early event in atherosclerosis, through direct interference with elastic fiber flexibility. Second, we observed aggregates of complement deposition within the vessel wall, the site at which plaque formation is now known to initiate. Third, we demonstrated that complement components are specifically present within the vasculature of mice with lupus-like syndromes as compared with controls. These observations, together with those of Manzi and colleagues, have led to the following specific aims that are based on our central hypothesis that the complement system may influence vascular stiffness and contribute significantly to the atherosclerotic process by directly reducing vascular elasticity within the arterial wall. The long-term goal of this proposal is to perform an initial characterization of the role of the complement system in atherosclerosis, using normal and abnormal human and mouse vascular systems. Specific Aim 1 is to characterize the spatial and temporal localization of complement proteins C3 and C4 within the arterial wall. Specific Aim 2 is to characterize the distribution of complement C3 and C4 within the arterial tree. Specific Aim 3 is to determine the capacity of complement C3 and C4 within the arterial wall to increase arterial stiffness. These studies will represent the first rigorous investigation of the role of the complement system in atherosclerosis, using SLE as a model of accelerated coronary vascular disease. Ultimately, the data generated by the proposed studies should identify therapeutic targets in SLE and in atherosclerosis in general.

Principal Investigator & Institution: Friedman, Morton H.; Professor; Biomedical Engineering; Duke University Durham, Nc 27706 Timing: Fiscal Year 2001; Project Start 01-APR-1999; Project End 31-MAR-2003 Summary: The long-term objectives of this research are: (1) to identify geometric features of the vasculature that enhance arterial susceptibility to atherosclerotic disease and can be used for early identification of individuals accordingly at risk, and (2) to understand the role of mechanical factors in the localization and pathobiology of atherosclerosis. To achieve the first objective, relationships are sought between in vivo measurements of the geometric features of human coronary arteries and the pathology of the vessels, with a focus on the early lesion. The second objective is furthered by computing the distribution of fluid dynamic and intramural stresses in selected vessel segments, and seeking correlations between these variables and the thicknesses of the vascular intima and media, as measured in vivo. Clinical biplane coronary cineangiograms of sixty patients at The Ohio State University and Wake Forest University School of Medicine will be processed digitally to reconstruct the threedimensional (3-D) course of the medial axes of selected segments of the left anterior descending and right coronary artery trees. Quantitative geometric parameters of the segments, including both static and dynamic measures of arterial geometry and

measures of vessel kinematics, will be obtained from the axes using objective computer algorithms. Variations in geometry among individuals will be assessed. Intravascular ultrasound (IVUS) records of the same segments will be obtained and processed to yield detailed measurements of vessel morphometry collocated to the vessel axes. Doppler flow data and phasic pressure will also be acquired. Relations will be sought between the geometric variables from the angiograms and morphometric parameters derived from the IVUS records; and analysis will take into account individual variability with respect to the traditional risk factors for atherosclerosis. The dynamic data from the angiograms will be used in model calculations to estimate the effect of vessel motion and bending on the flow fieled and wall stresses. For twelve cases, the angiographic and IVUS records will be used to describe the 3-D lumen and wall of a portion of the vessel in diastole. The flow fieled and wall stresses in this region will be simulated numerically, using the Doppler and pressure data as input; the first flow calculation will be validated experimentally. By comparing the computed distribution of stresses acting on and in the vessel segment against that of intima/media thickness, inferences will be drawn regarding the role of mechanical forces in relation to human atherosclerosis.

Project Title: DENDRITIC CELL MIGRATION IN ATHEROSCLEROSIS Principal Investigator & Institution: Randolph, Gwendalyn J.; Assistant Professor; Inst/Gene Therapy & Mol Med; Mount Sinai School of Medicine of Nyu of New York University New York, Ny 10029 Timing: Fiscal Year 2001; Project Start 30-SEP-2001; Project End 31-JUL-2005 Summary: (provided by applicant): During initiation of immune responses, dendritic cells migrate from sites of antigen capture to the T cell zones of lymphoid organs to activate antigen-specific T cells. It remains to be determined whether dendritic cells that enter or develop within atherosclerotic plaques migrate from the plaques, and if so, whether T dependent immune responses that may thereby develop against plaque antigens lead to progression of atherosclerosis. In contrast to our incomplete state of knowledge regarding the role of dendritic cells and T cells in atherosclerosis, evidence that macrophages are involved in the initiation and progression of atherosclerotic lesions is quite strong. Monocytes are well known as the precursors for macrophages, but monocytes can also become dendritic cells in vitro, when cultured with specific exogenous cytokines or when cocultured with endothelial cells, and in vivo. In both human and mouse models, the capacity of monocyte-derived cells to leave tissues is associated with their development into dendritic cells, giving rise to the hypothesis that differentiation of monocytes into dendritic cells may favor their clearance from atherosclerotic plaques. Taking this view, development of dendritic cells from monocytes within the plaque would tend to promote regression. On the other hand, the migration of monocyte-derived dendritic cells from atherosclerotic plaques may favor the development of T-dependent immune responses that potentially mediate the progression of lesions. Our preliminary evidence indicates that monocyte-derived dendritic cell migration is impaired greatly in apoE-deficient mice, supporting the former hypothesis. In the present study, we will further characterize the status and function of dendritic cells in apoE- and LDL receptor-deficient mice. Then we will study whether monocyte and macrophage-derived cells migrate from atherosclerotic lesions during regression of plaques and what routes of migration they may take. The phenotype of any such migrating cells will be assessed, particularly with regard to whether emigrating cells have developed into dendritic cells. The significance of migration from the plaques will be investigated using apoE-/- mice that are deficient in

molecules that mediate migratory clearance of dendritic cells from tissues. The long term goal of this work is to define how antigen presenting cells, particularly those derived from monocytes, participate in progression and regression of atherosclerosis, with a view toward understanding how manipulating the function of these cells may favor regressive disease.

Project Title: DIFFERENTIAL MECHANISM OF BAROREFLEX DYSFUNCTION IN ATHEROSCLEROSIS AND AGING Principal Investigator & Institution: Chapleau, Mark W.; Associate Professor; University of Iowa Iowa City, Ia 52242 Timing: Fiscal Year 2003; Project Start 21-JAN-2003; Project End 31-DEC-2007 Summary: Compelling evidence implicates reactive oxygen species (ROS) in causing neuronal and cardiovascular dysfunction in atherosclerosis and aging. The goals of the proposed project are to define the role of ROS in causing baroreflex dysfunction in these states and to determine effects of combined atherosclerosis and aging on baroreflex sensitivity. The first hypothesis to be tested is that ROS impair baroreflex function through differential effects on afferent and central components of the reflex. The defect may be primarily in the afferent limb in atherosclerosis, whereas both components may be impaired in aging. The relative importance of alterations in afferent and central components of the baroreflex in atherosclerotic and senescent mice will be determined through direct recordings of aortic depressor nerve activity, renal sympathetic nerve activity, arterial pressure and heart rate; and measurement of responses to drug-induced changes in arterial pressure and electrical stimulation ofbaroreceptor afferents in the aortic depressor nerve. The role of ROS will be assessed through treatment with membrane permeable superoxide dismutase/catalase mimetics and by studies of genetically-modified mice deficient in antioxidant molecules (e.g. MnSOD and CuZnSOD) and transgenics that over-express antioxidant enzymes. The second hypothesis to be tested is that the mechanism of the ROS-mediated decrease in baroreceptor sensitivity differs in atherosclerosis and aging. Vascular NAD(P)H oxidase is proposed as the source of ROS in atherosclerosis while mitochondria in baroreceptors are proposed as the source in aging. Studies in genetically-modified mice, adenoviralmediated gene transfer, and pharmacological antagonists will enable selective manipulation of ROS in subcellular compartments in specific cell types to reveal the sources of ROS generation. Furthermore, neuronal ROS generation and its effects on membrane excitability and ionic currents will be directly assessed in studies of cultured baroreceptor neurons isolated from control, atherosclerotic and senescent mice. The proposed studies are expected to have important implications for understanding mechanisms of baroreflex dysfunction in patients with atherosclerosis and in the elderly. The results may be particularly relevant to humans where atherosclerosis is common in the elderly. Antioxidant therapies are currently receiving much attention as promising agents in the prevention and treatment of cardiovascular disease. Knowledge gained from the proposed studies may impact on future use of antioxidant therapies. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Timing: Fiscal Year 2001; Project Start 30-SEP-1999; Project End 31-MAY-2002 Summary: Cardiovascular disease is the leading cause of morbidity and mortality in Westernized populations. Thus, the role of dietary micronutrients in decreasing LDL oxidation assumes considerable significance. The most consistent data with respect to micronutrient antioxidants and atherosclerosis appears to relate to alpha-tocopherol (AT), the predominant lipid-soluble antioxidant in LDL. In addition to decreasing LDL oxidation, data support an effect of ET on critical cells in atherogenesis (monocytes, smooth muscle cells and endothelium) that are potentially anti-atherogenic. The primary aim of the present proposal is to test the effect of AT supplementation (1200 IU/day of RRR-AT) in a placebo-controlled, randomized double blind trial over 2 years on the progression of carotid atherosclerosis in patients with coronary artery disease (stable angina pectoris or previous myocardial infarction). Subjects (n=120) recruited would have to be on the American Heart Association Phase II diet and a HMG CoA reductase inhibitor for at least one year and have an LDL cholesterol ,125 mg/dL on 2 visits at least 4 weeks part during the 10 month lead in phase. Intimal-medial thickness (IMT) of both carotids, including the common carotid, the bulb and the proximal internal carotid will be determined by high resolution B-mode sonography. At six month intervals blood samples will be obtained for liver enzymes, creatinine, complete blood count, lipid profile, antioxidant and fatty acid levels, LDL oxidation, plasma soluble CAMs (cell adhesion molecules) and monocyte activity. Also, an early morning urine sample will be obtained for F2-isoprostanes, a direct measure of lipid peroxidation. IMT will be determined at baseline, 1, 1.5 and 2 years. The mean change in IMT and rate of progression will be compared between the AT and placebo groups. Following isolation, the LDL will be subjected to copper catalyzed oxidation over a 5hour period. From this will be obtained the lag phase and oxidation rate. Isolated monocytes will be activated with lipopolysaccharide and the following activities assayed: superoxide anion release, interleukin-1beta release and adhesion to human endothelium. F2 isoprostanes and VAM, ICAM, and E-& P-selectin will be quantitated by ELISA. AT levels and the parameters of LDL oxidation and monocyte activity will be correlated with changes in IMT. If this study show that high-dose AT supplementation is beneficial in retarding atherosclerosis this could emerge as an important adjunctive therapy in the management of cardiovascular disease.

Principal Investigator & Institution: Sachais, Bruce S.; Pathology and Lab Medicine; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2001; Project Start 15-JAN-2000; Project End 31-DEC-2004 Summary: (Adapted from applicant's abstract) Atherosclerosis is the most common cause of death in the United States. Elevated plasma levels of LDL are a major risk factor for the development of this disease. The major pathway by which LDL is catabolized is via the LDL-receptor (LDL-R). Therefore, factors that impede LDL-LDL-R interactions promote atherosclerosis. An unexplored question is whether platelet activation modulates LDL-R function. Whereas the role of platelets in the terminal thrombotic phase of this disease is well- established, it is less certain whether persistent platelet activation accelerates the pathogenesis of the atherosclerotic plaque. In view of the fact that certain clusters of positively charged residues on apolipoprotein Beta-100 are required for optimal binding of LDL to the LDL-R, the investigators tested the hypothesis that platelet factor 4 (PF4], an abundant lysine rich protein released upon

platelet activation, can complete for receptor binding and thereby impede lipoprotein clearance and catabolism. Pilot data provided support for this hypothesis by demonstrating that PF4 binds to the LDL-R with nM affinity, inhibits the binding and degradation of LDL in vitro, and prolongs the plasma clearance of LDL in vivo. It is now proposed to study the biochemicals basis of the PF4-LDL-R interaction in greater detail and to develop models to elucidate the role of this platelet protein in the development of atherosclerosis through the following specific aims; 1) Specific Aim 1: Characterization of PF4 binding to the LDL-R and it's consequences in vitro. The binding kinetics of PF4 to cell lines that overexpress LDL-R as well as to recombinant soluble receptor will be measured using surface plasmon resonance. The effect of PF4 on the binding and cellular metabolism of LDL and apoE will be studied using cells that are genetically lacking or overexpress LDL-R and in which the level of proteoglycan expression has been controlled. Specific Aim 2: Effect of PF4 on lipoprotein metabolism and atherosclerosis in vivo. Adenoviral-mediated gene transfer of PF4 will be used to analyze changes in LDL clearance and endogenous lipoprotein levels in vivo. The propensity to develop hyperlipidemia and atherosclerosis will be examined in transgenic mice that overexpress human PF4. These studies are designed to gain insight into a novel mechanism by which persistent platelet activation may promote the development of atherothrombotic disease. An understanding of the structural basis of the PF4-LDL-R interaction may identify a potential locus for therapeutic intervention. This research proposal is part of comprehensive training program designed to prepare the applicant for a career as an independent investigator in the field of vascular biology.

Project Title: EFFECTS OF ENERGY HEALERS ON ATHEROSCLEROSIS Principal Investigator & Institution: Fox, Joan E.; Director; Cleveland Clinic Foundation 9500 Euclid Ave Cleveland, Oh 44195 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-MAY-2004 Summary: (provided by applicant): Coronary artery disease is the major cause of death and disability in the United States. The goal of our research for the past 20-years has been to investigate mechanisms involved in the development of cardiovascular disease and to identify potential sites for therapeutic intervention. Evidence that poor social support systems and emotional states play a major role in the development and progression of coronary artery disease is accumulating; interventions designed to address the emotional state of the patient have demonstrated beneficial effects. The rapidly growing field of psychoneuroimmunology is providing insights into potential mechanisms by which emotional health could affect physical health. There is growing interest in the use of interventional programs that include practices such as meditation and yoga that are based on Eastern spiritual philosophies. A basic premise of these philosophies is that we are interconnected through an unidentified life-force. Energy healers suggest that this life-force may be a component of emotionally supportive social interactions. They claim to be able to channel this life-force to clients, thus improving the emotional and spiritual health of the client. Several positive trials on energy healing, including two positive trials on cardiac patients, suggest that this CAM modality is worthy of further study. Cholesterol-fed rabbits provide a well-established model for evaluation of the effects of potential therapeutic agents on the development of atherosclerosis. A marked reduction in the development of lesions in rabbits receiving caring attention has been reported. In this application, we propose a pilot study using cholesterol-fed rabbits. The effect of energy healing treatments on lesion development will be investigated. Should these studies provide evidence for beneficial effects, the

availability of an animal model would allow the design of future studies in which effects on physiological markers, sites of action, or important features of delivery of energy healing could be investigated in detail. The Specific Aims of the present application are: 1) to evaluate the possibility that energy healing treatments may decrease the progression of atherosclerosis in a rabbit model of cholesterol-induced atherosclerosis, 2) to evaluate the possibility that energy healing treatments may decrease markers of neuroendocrine and sympathetic nervous system activation in a rabbit model of cholesterol-induced atherosclerosis 3) to evaluate the possibility that energy healing treatments can minimize the activation of endothelial cell gene transcription in a rabbit model of cholesterol-induced atherosclerosis.

Project Title: ENDOTHELIAL DYSFUNCTION IN ATHEROSCLEROSIS Principal Investigator & Institution: Southan, Garry J.; Inotek Pharmaceuticals Corporation 100 Cummings Ctr, Ste 419E Beverly, Ma 01915 Timing: Fiscal Year 2002; Project Start 01-MAY-2002; Project End 31-OCT-2003 Summary: Nitric oxide and peroxynitrite are reactive, short-lived species that are important mediators of atherosclerosis. One of the downstream pathways of peroxynitrite-mediated vascular injury is related to activation of the nuclear enzyme poly (ADP-ribose) synthetase (PARS). Based on vitro and in vivo preliminary data, the applicants propose that the PARS pathway may play a role in the pathogenesis of the endothelial dysfunction associated with atherosclerosis, and propose studies to directly test this hypothesis. The first aim of the current project is to establish time course of PARS activation and associated vascular dysfunction in atherosclerosis, and to correlate these alterations with reactive nitrogen species formation in the vasculature. Blood vessels will be obtained form mice at various time points after initiation of atherosclerotic changes, induced by two distinct experimental models (collar and Apo/E models). Reactive nitrogen species formation and PARS activation will be investigated using immunohistochemistry, vascular reactivity will be investigated using ex vivo using isometric tension measurements in vascular chambers. The second aim of the project is to perform direct studies into the role of PARS-related endothelial dysfunction, as it relates to the atherosclerosis-associated development of endothelial dysfunction. We will utilize chronic oral treatment with PARS inhibitors of two different classes, followed by evaluation of changes in vascular reactivity and the progress of atherosclerosis. Our studies will provide novel mechanistic information on atherosclerosis-related endothelial dysfunction which will be utilized for the future design and commercial development of novel vasculoprotective agents. PROPOSED COMMERCIAL APPLICATIONS: The annual anticipated revenues for an effective agent for the therapy of atherosclerosis is over 50 billion in the US alone.

success in basic research of coronary physiology and shows promise of attaining independent status. The proposed studies will be performed in well-funded and established laboratories under the co-sponsorship of Drs. Beverly Davidson and David Gutterman at the University of Iowa. Environmental support and facilities available to him are outstanding. The proposed studies will provide the applicant training in cellular and molecular biology which will allow him to integrate these disciplines and extend his physiologic studies. The training and experience outlined in this proposal will be invaluable in the applicant's goal to be competitive as an academic cardiologist in the field of vascular biology. There are studies of the hypotheses that 1) atherosclerosis impairs endothelium-dependent vasodilation of the human coronary microcirculation as a result of increased oxidative stress, and that 2) vascular dysfunction can be improved by endothelial cell overexpression of superoxide dismutase. The proposal is novel in its study of diseased human coronary microvessels and the use of gene transfer to correct clinically important vascular abnormalities. Isolated atrial or ventricular arterioles, obtained fresh at the time of cardio-pulmonary bypass or cardiac transplant, will be prepared for videomicroscopic examination of internal diameter. The effect of acute (pyrogallol) and chronic (atherosclerosis) oxidative stress on endothelium-dependent dilation will be tested. The mechanism of impaired vasodilation in atherosclerosis will be determined by examining the sensitivity of vascular smooth muscle to nitric oxide and non-nitric oxide stimuli, evaluate the role of vasoconstrictor prostanoids, and assess for decreased cellular levels of SOD in atherosclerosis. The candidate will also determine whether overproduction of superoxide dismutase is protective against reactive oxygen species mediated dysfunction. In-vitro adenoviral transfer of genes for three human SOD isoforms (manganese, copper-zinc, or extracellular), each with specific cellular localization, will be performed in arterioles from patients with and without atherosclerosis. Functional changes of endothelial vasodilation in these vessels will be tested. Preliminary data by the applicant support the feasibility of the proposed studies. Species differences of vascular biology and limitations in animal models of disease underscore the importance of performing these studies.

Project Title: ENVIRONMENT, CNS, AND ATHEROSCLEROSIS IN AN ANIMAL MODEL Principal Investigator & Institution: Mccabe, Philip M.; University of Miami Coral Gables University Sta Coral Gables, Fl 33124 Timing: Fiscal Year 2001; Project Start 01-JUL-1986; Project End 31-JUL-2006 Summary: (provided by applicant): We have demonstrated that social behavioral factors can influence the progression of atherosclerosis in an animal model genetically predisposed to the development of disease, the Watanabe Heritable Hyperlipidemic Rabbit (WHHL). It was found that stable social conditions, accompanied by increased affiliative social behavior, slowed the progression of atherosclerotic lesions in these animals. In contrast, animals in unstable social conditions, displaying increased agonistic behavior, and animals housed singly exhibited significant aortic pathology. These data could not be explained entirely by resting plasma glucocorticoids, gonadal steroids, lipid levels, nor resting cardiovascular measures. It is hypothesized that chronic activation of the sympathetic nervous system (SNS) accelerates the progression of atherosclerosis. In addition, we will examine Central Nervous System (CNS) mechanisms underlying the regulation of the SNS and hypothalamic pituitary adrenocortical axis (HPA), focusing primarily on the roles of central corticotropinreleasing hormone (CRH) and oxytocin (OT) in the control of SNS and HPA responses.
32
Atherosclerosis
It is hypothesized that CRH, released centrally during stressful behavior, stimulates the SNS and HPA, thereby accelerating the progression of disease. In contrast, central OT, which has been linked to increased affiliative behavior, may buffer the organism during stable social conditions from the effects of stress by inhibiting the HPA axis and SNS activity. Animals housed singly exhibited low glucocorticoid levels and showed little stressful behavior, yet still developed significant atherosclerosis. These sedentary animals gained more body weight than the other groups and developed profound hyperinsulinemia, suggesting that risk factors related to the Insulin Metabolic Syndrome may be particularly important for the progression of disease in this group. The proposed work will: 1) assess the role of the SNS in behaviorally-related atherosclerosis via selective adrenergic receptor antagonists, 2) determine the role of central CRH in the regulation of SNS activity and atherosclerosis during chronic social stress via a centrally administered CRH antagonist, 3) measure changes in the release of OT in the hypothalamic paraventricular nucleus as a function of social environment through the use of chronic microdialysis, 4) determine the role of central OT in the regulation of HPA and SNS activity, and its relationship to atherosclerosis via a centrally administered OT antagonist, 5) assess the impact of dietary restriction or daily exercise on risk factors related to the insulin metabolic syndrome and atherosclerosis and in individually-caged WHHLs, and 6) examine the influence of social environment on atherosclerosis in the heterozygous WHHL, an alternative model that more closely parallels lipid status and disease progression in a large percentage of humans.

Project Title: EPIDEMIOLOGY OF CAROTID ARTERY ATHEROSCLEROSIS IN YOUTH Principal Investigator & Institution: Davis, Patricia H.; Neurology; University of Iowa Iowa City, Ia 52242 Timing: Fiscal Year 2001; Project Start 30-SEP-1995; Project End 31-MAR-2004 Summary: (Adapted from Investigator's Abstract) The atherosclerotic process begins in childhood and progresses through adult life resulting in coronary heart disease (CHD), stroke, and peripheral vascular disease. There is a need to identify young people at risk for premature atherosclerosis so that preventive measures can be instituted before occlusive vascular disease occurs. The ultrasonic measurement of carotid intimal-medial thickness (IMT) allows detection of early atherosclerosis and is related to incident CHD and stroke in older adults. In 1970, a population of school age children and adolescents was first examined in Muscatine, Iowa. A sample of 776 members of this longitudinal cohort, who are representative of the initial childhood population, is now aged 37 to 45 years. Their risk factors were measured in childhood, young adulthood and twice in later adult life, and they have undergone measurement of carotid IMT as well as electron beam computed tomography to identify coronary artery calcification (CAC). In this cohort, carotid IMT is significantly associated with CAC as well as current LDL cholesterol and systolic blood pressure, but only 14 percent of carotid IMT variability can be explained by these risk factors. Parents of the cohort have been assessed for cardiovascular morbidity and mortality. In this application the investigators propose to do the following: (1) examine the third generation to determine whether the offspring of cohort members with premature atherosclerosis and/or a familial history of cardiovascular disease have increased carotid IMT or elevated risk factors; (2) identify risk factors for progression of carotid IMT over four years in this cohort; and (3) measure putative risk factors for increased IMT (serologic evidence of Clamydia pneumoniae or cytomegalovirus infection, high sensitivity C-reactive protein,

fibrinogen, plasminogen activator inhibitor-1 and glycosylated hemoglobin). The investigators state that the study has the potential of providing information which would allow identification of subjects at risk for atherosclerosis at an early age and may lead the way to interventions to halt or slow progression of atherosclerosis prior to the development of clinical disease.

Project Title: EPIDEMIOLOGY OF CAROTID IMT PROGRESSION IN MESA Principal Investigator & Institution: Polak, Joseph F.; New England Medical Center Hospitals 750 Washington St Boston, Ma 021111533 Timing: Fiscal Year 2003; Project Start 15-JUN-2003; Project End 31-MAY-2008 Summary: (provided by applicant): This application seeks to determine the factors associated with progression of sub-clinical atherosclerosis and to evaluate the associations between the progression of sub-clinical atherosclerosis and the development of clinically manifest atherosclerosis. Changes in sub-clinical atherosclerotic disease are measured noninvasively using high resolution B-mode ultrasound and presented as changes in wall thickness (in millimeters) of the carotid artery (carotid IMT). Carotid IMT is well recognized as a measure of atherosclerotic burden. Progression of disease is hypothesized to precede the development of clinical events. The current application is also designed to be able to compare progression of carotid IMT with changes in coronary calcium score, a measure of coronary artery disease. Development of clinical atherosclerosis is evaluated by onset of clinical events (myocardial infarction, stroke, angina.) in an established cohort with a broad agedistribution and a multi-ethnic composition (MESA: Multi-Ethnic Study of Atherosclerosis). As compared to previous published works on the topic, this application offers the opportunity of measuring atherosclerosis across a broad age distribution and in a multi-ethnic cohort using state-of-the-art technologies.

A reduction of saturated fat intake and an increase in plant foods has both been associated with beneficial effects on serum cholesterol, hypertension, atherosclerosis and mortality. These dietary and lifestyle modifications are hypothesized to act by increasing antioxidant protection and reducing oxidative damage. Such damage is a primary mechanism in the development of atherosclerosis, as demonstrated by numerous basic science studies and suggested by several small human feeding trials. Specific oxidatively modified macromolecules have been found in advanced atherosclerotic lesions. However, no information is available on the early time course of oxidative damage in human subjects. The investigators propose to measure oxidation products from several classes of compounds, thereby studying multiple pathways in atherogenesis, and serum antioxidants. They will study a cohort of about 3500 black and white young men and women. Between June, 2000 and June, 2001 (15 years after baseline), CARDIA participants will be assessed for subclinical CHD by the

measurement of coronary calcification at the earliest stages of detectability. In addition, endothelial dysfunction will be assessed by measurement of plasma adhesion molecules and microalbuminuria. By measuring several kinds of antioxidants and assessing oxidative damage in classes of compounds, this project will test the association of oxidative damage and early/subclinical CHD. In addition, utilizing the extensive biochemical and sociodemographic data collected over the first 15 years of CARDIA, they will define the confounding effects of traditional CHD risk factors. The investigators state that the analyses will allow testing several major hypotheses about the early evolution atherosclerosis and CHD. They further state that the conclusions will identify new strategies for the prevention of CHD. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: ESTROGEN, INFLAMMATION AND ATHEROSCLEROSIS Principal Investigator & Institution: Herrington, David M.; Professor; Internal Medicine; Wake Forest University Health Sciences Winston-Salem, Nc 27157 Timing: Fiscal Year 2001; Project Start 21-SEP-2000; Project End 31-JUL-2003 Summary: (Adapted from the Investigator's Abstract) Recently, the Heart and Estrogen/progestin Replacement Study (HERS) found no effect of 4.1 years of estrogen plus progestin therapy in women with established coronary disease. Recent data showing elevated levels of C-reactive protein (CRP) in women taking hormone replacement (HRT) suggest that this null effect in HERS could be due to a previously unrecognized pro-inflammatory effect of HRT offsetting the other benefits of estrogen. However, there are several important questions remain concerning HRT, CRP, and atherosclerosis. First, do the estrogen-associated changes in CRP reflect a true increase in systemic vascular inflammation mediated through interleukin-6 (IL-6) and other inflammatory cytokines, or are they simply due to a direct effect of estrogen on hepatic synthesis of CRP? Second, are baseline measures of CRP and other inflammatory markers, or estrogen-associated change in these markers related to subsequent progression of angiographically defined coronary atherosclerosis? To answer these questions, the investigators propose to measure CRP and other inflammatory markers in stored serum from participants in the Estrogen Replacement and Atherosclerosis (ERA) trial, an NHLBI-sponsored angiographic trial to examine the effects of daily conjugated estrogen (0.625 mg) or estrogen plus medroxyprogesterone acetate (MPA) (2.5 mg) on progression of coronary disease in postmenopausal women. By examining the relationships between these measures, treatment assignment, and progression of coronary atherosclerosis, they hope to clarify the effects of estrogen use on vascular inflammation and the consequences of these effects for the pathogenesis of atherosclerosis. The investigators state that this information may help guide clinical decision-making and future research initiatives because of the fundamental role that estrogen therapy and vascular inflammation play in modulating risk for heart disease in women.

Studies
35
pregnancy is associated with enhanced fatty streak formation in fetuses and a much faster progression of atherosclerosis in normocholesterolemic children that could not be explained by conventional risk factors. Although in humans inherited genetic differences are likely to contribute, we hypothesize that maternal hypercholesterolemia per se induces pathogenic events in fetal arteries that determine their later susceptibility to atherosclerosis. We also hypothesize that oxidative stress caused by maternal hypercholesterolemia leads to persistent changes in the expression of genes modulating atherogenesis. An important corollary is that cholesterol lowering and antioxidant interventions in mothers during pregnancy may provide long-lasting benefits to their offspring. Using genetically homogeneous animal models, we recently provided direct evidence for the causal role of maternal hypercholesterolemia and oxidative stress in both enhanced fetal lesion formation and accelerated post-natal atherogenesis. We also provided proof in principle for persistent regulation of gene expression in the arterial wall. We now propose to better define the in utero programming associated with maternal hypercholesterolemia, to identify genes influencing post-natal susceptibility to atherosclerosis, and to investigate whether interventions during pregnancy also decrease the susceptibility in offspring of "normocholesterolemic" mothers. Different levels of maternal hypercholesterolemia and antioxidant protection will be achieved by transferring embryos of LDL receptor deficient (LDLR-/-) mice into treated or untreated C57BL/6, LDLR -/- or apoE -/- mice. Offspring will be subjected to post-natal atherogenic conditions and lesion formation followed over time. Laser-capture microdissection, gene microarray and PCR techniques will be used to determine persistence of gene regulation and its correlation with atherosclerosis, immunocytochemical presence of gene products and measurements of oxidative stress. These studies should yield fundamentally new insights into in utero programming and atherogenic mechanisms, and may establish a novel preventive approach.

We have developed a multidisciplinary approach incorporating gene mapping in animals and in man with human and animal physiologic analyses that involve extensive phenotyping of traits related to IR and atherosclerosis to test this hypothesis, Because of their family structure and the high prevalence of IR, Mexican American (MA) families with CAD represent an ideal ethnic group in which to identify genes linking to both IR and CAD and to determine the critical physiologic relationships of IR and hyperinsulinemia and its associated metabolic changes to vascular structural alterations leading to atherosclerosis. Exciting preliminary data in MA families supports both our hypothesis and the overall feasibility of completing the goals outlined in this grant application. Three experienced teams of senior research investigators and three supportive cores constitute a highly focused, collaborative, integrated investigation that features expertly designed and performed phenotyping; innovative methods of mathematical genetic analysis pioneered and

An important theme of this program project is gene->cell->tissue->animal- >human>gene translation. The combination of detailed human and animal phenotyping, comprehensive genetic mapping, novel tissue investigations and lipid turnover studies outlined herein provides a powerful, multi- dimensional approach to identify genes and pathophysiologic mechanisms linked to atherosclerosis.

AND
Principal Investigator & Institution: Tannock, Lisa R.; Medicine; University of Washington Seattle, Wa 98195 Timing: Fiscal Year 2001; Project Start 18-JUN-2001; Project End 31-MAY-2003 Summary: (APPLICANT'S ABSTRACT): Glucosamine is a nutritional supplement commonly used for the relief of joint pain. However, it is not subject to FDA regulation and its long-term safety is unknown. Glucosamine is used in the synthesis of glycosaminoglycan chains on proteoglycans. Vascular proteoglycans play a key role in atherogenesis due to their retention of atherogenic lipoproteins in the arterial wall. Thus, glucosamine use could potentially be atherogenic. Previous studies have yielded conflicting results with respect to the atherogenic potential of glucosamine. Some studies have suggested that glucosamine may have pro=atherogenic effects, while others suggest an anti-atherogenic effect. This grant proposes to investigate the role of glucosamine in vascular. proteoglycan biosynthesis and lipoprotein retention in vitro, andin vivo. The major hypothesis of this grant is that glucosamine supplementation will result in altered proteoglycan synthesis by vascular-smooth muscle cells, which will in turn result in an altered propensity to atherosclerosis. Depending on the nature of these altered vascular proteoglycans, glucosamine supplementation could either enhance susceptibility to, or protect against, atherosclerosis. This grant proposes to study the effect of glucosamine supplementation on the structure and function of proteoglycans synthesized by monkey aortic smooth muscle cells in vitro. Studies will be performed to determine the effect on-degree of sulfation, size, and ratio of classes of proteoglycans synthesized by vascular smooth muscle cells, and the retention of atherogenic lipoproteins by these altered proteoglycans. In addition, this grant proposes to address the effect of glucosamine supplementation in vivo. LDL receptor deficient mice, a mouse model of atherosclerosis that has a human-like lipoprotein profile, will be supplemented with oral glucosamine, and the extent of atherosclerotic lesions will be determined. The findings from the proposed study should provide important insights into the potential effects of glucosamine supplementation on atherosclerotic cardiovascular disease.

Timing: Fiscal Year 2001; Project Start 30-SEP-1995; Project End 31-JUL-2006 Summary: This program project will investigate the role of hyperglycemia and insulin resistance in the excess cardiovascular disease due to diabetes. The program will utilize innovative and multi-disciplinary approaches to address the overall unifying theme that elevate glucose and/of insulin resistance leads to accelerated cardiovascular disease by increasing oxidative stress and inflammatory signals in the vessel wall. A hypothesis developed in the initial funding period will be expanded to evaluate the role of lipoxygenase (LO) activation in mediating the oxidative and inflammatory changes associated with atherosclerosis and vascular injury. A strength of the program will be the use of both small and large animal models to more clearly evaluate the genetic and molecular mechanisms leading to cardiovascular disease in diabetes. These models will also allow the evaluation of potentially therapeutic to prevent the accelerated atherosclerosis and injury response in people with diabetes. The program involves 4 projects and 3 cores. Project 1 will examine the hypothesis that activation of LO pathway can play a role in atherosclerosis and vascular injury by inducing the transcriptional regulation of key genes which regulate vascular smooth muscle cell migration and matrix remodeling. A unique aspect of this project will be the use of novel ribozymes and animal models to test the in vivo role of oxidative stress and 12-LO in these processes. Project 2 will test the hypothesis that glucose and the diabetic state induce LO expression in aortic endothelial cells and that arachidonic or linoleic acid derived oxidative lipids activate key signalling mechanisms and oxidative phospholipids which lead to the binding of monocytes to the vessel wall. This project will utilize novel ribozymes, mouse, and swine models in the cores. Project 3 will mechanistically evaluate the role of helix-loop-helix transcription factors such as Id3 in accelerated VSMC growth response to injury in insulin resistant and diabetic states. Studies will utilizes chemokines, and chemokine receptors determine monocyte recruitment to atherosclerotic lesions and b) the increased rate of atherosclerosis in diabetes can in part be explained by a more robust or earlier expression of these molecules. A novel aspect of this project will be the use of in isolated perfused carotid artery model and the therapeutic and mechanistic actions of a novel anti- inflammatory agent Lisofylline in appropriate mouse models. The synergy between the projects and use of the cores will greatly accelerate the pace of this research to understand the mechanisms of accelerated macrovascular disease in diabetes. The results form this program should provide new therapeutic advances to reduce the rate of cardiovascular disease in diabetes. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

hyperlipidemia, hypertension and diabetes, will be discussed. Throughout special emphasis will be placed on cutting edge technologies and resources that are relevant to the biology of atherosclerosis. Accordingly, there will be discussion of functional genomics, expression arrays, proteomics, sequence database utilization and new approaches in human and mouse genetics. Nine sessions are planned and will cover the following topics: 1. Etiology of Atherosclerosis: Lipoproteins and other Risk Factors (hypertension, diabetes, homocystinemia); 2. Lesion Initiation; 3. Inflammation; 4. Foam Cell Formation and Regression; 5. Complexity of Lesions; 6. Plaque Rupture and Thrombosis; 7. Genomic Approaches; 8. Intervention and Diagnosis; 9. The Genome Project and Vascular Disease. The conference will be a major vehicle for the integration of new knowledge in the field of atherosclerosis research. In order to stimulate an interdisciplinary dialogue, speakers will be invited who represent distinct but overlapping areas of research such as hypertension, genomics, lipoproteins and vascular biology. The conference will encourage the participation of women and minorities. Some of the invited speakers represent young scientists at the beginning of their independent careers. Participation of young scientists will also be encouraged through poster sessions. The conference is planned in such a way that by the end of the conference, the participants will have derived an overall understanding of the biogenesis of atherosclerosis, and will have a clear picture of the latest most exciting developments in the field.

Project Title: GROUP V SPLA2 IN ATHEROSCLEROSIS Principal Investigator & Institution: Webb, Nancy R.; Medicine; University of Kentucky 109 Kinkead Hall Lexington, Ky 40506 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2008 Summary: (provided by applicant): A critical event in early atherogenesis is the retention of low-density lipoprotein (LDL) particles in the subendothelium through their binding to intimal proteoglycans. These retained lipoprotein particles are exposed to several modifying enzymes in the arterial wall, including lipases, oxidizing enzymes, and proteases. A multitude of biological responses to such modified LDL, including the recruitment and lipid loading of macrophages, leads to the initiation and progression of atherosclerosis. The extracellular matrix (ECM) appears to play an active role in this process by not only mediating the retention of LDL particles, but by also modulating the activity of various enzymes towards LDL. Thus, in regions where LDL is being accumulated, the co-localization of LDL, ECM, and LDL modifying enzymes leads to a self-perpetuating cascade of events that culminates in atherosclerosis. The identification and characterization of molecules and the manner in which they interact to contribute to this process, is central to our understanding the mechanisms that underlie susceptibility to lesion formation. This proposal aims to study a novel form of secretory phospholipase A2, Group V sPLA2, which we now show is present in human and mouse atherosclerotic lesions specifically associated with macrophages. We hypothesize that Group V sPLA2and LDL in the proximity of macrophages leads to the localized production of aggregated and/or fused lipoprotein particles, which consequently leads to foam cell formation. To test this hypothesis, the following specific aims are proposed: Specific Aim 1): To test the hypothesis that Group V sPLA2 produces modifications in LDL particles that lead to increased uptake by macrophages. This will be accomplished by analyzing LDL particles after hydrolysis by Group V sPLA2 to determine particle composition, density, and extent of aggregation and/or fusion; quantifying the effect of Group V sPLA2 hydrolysis on the delivery of LDL lipid to macrophages, and

determining whether other factors in the arterial subendothelium, namely sphingomyelinase and ECM, promote Group V sPLA2-mediated effects. Specific Aim 2): To test the hypothesis that macrophage expression of Group V sPLA2 in the vessel wall results in increased atherosclerosis. This will be achieved by transplanting fetal liver hematopoetic stem cells over-expressing wild-type Group V sPLA2, or a mutant form of the enzyme that is deficient in proteglycan binding, into LDL receptor-/- mice. Measuring lesion size and cholesterol/cholesterol ester content will assess the extent of atherosclerosis. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: GSTS: OXIDATIVE STRESS IN EARLY ATHEROSCLEROSIS Principal Investigator & Institution: Boor, Paul J.; Professor; Pathology; University of Texas Medical Br Galveston 301 University Blvd Galveston, Tx 77555 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2007 Summary: Atherosclerosis is a major cause of morbidity and mortality. Oxidative stress has been strongly implicated in the pathogenesis of atherosclerosis, but few studies have addressed the mechanisms by which the vascular wall defends against oxidant, or electrophilic, injury. Our recent data show that a specific subtype of glutathione Stransferase (GST), GST A4-4, is selectively induced in vascular smooth muscle cells (VSMCs) of rat aorta in response to electrophilic injury caused by alpha, betaunsaturated aldehydes such as acrolein, 4-hydroxynonenal (4-HNE) and 4hydroxyhexenal (4-HHE), which are toxic end products of lipid peroxidation implicated in the pathogenesis of atherosclerosis. Our recent data in human tissue also supports a role for HGST A4-4 in the pathogenesis of atherosclerosis. Our recent data in human tissue also supports a role for HGST A4-4 in the atherosclerotic plaque. Our hypothesis is that the human vascular GST isozyme, HGST A4-4, functions in the cell's defense against highly reactive alpha, beta- unsaturated aldehydes that are toxic end products of lipid peroxidation, and are implicated in the pathogenesis of atherosclerosis. We expect hGST A4-4 is induced in vascular smooth muscle cells (VSMC) and endothelium during development of the early human atherosclerotic plaque in response to oxidative stress. By manipulating this enzyme in cultured vascular cells from rat, and in genetically altered in vivo mouse models (GST-/-; apoE-/-; a double knock of apoE and GST) we will be able to alter the course of oxidative injury and atherogenesis. Using human blood vessels , our Specific Aim #1 will determine if HGST 4-4 induction and accumulation of suspected aldehyde/aldehyde adducts are early markers of oxidative injury in the early or "fibrous" human atherosclerotic plaque. In Specific Aim #2, we will utilize already- developed rat VSMC, and endothelial cells made resistant to alpha, betaunsaturated aldehydes, to examine the role of GST during oxidative/atherosclerotic stress. In Specific Aim #3 we will use a recently developed genetically altered mouse GST during oxidative/atherosclerotic stress. In Specific Aim #3 we will use a recently developed genetically altered mouse GST knockout of GST and apoE, to manipulate GST A4-4 in order to worsen/hasten the development of atherosclerosis. These studies will focus on early events during oxidative damage and defense mechanisms in the vascular wall, so that therapeutic strategies to prevent initiation and propagation of the atherosclerotic plaque may be devised.

Atherosclerosis
Timing: Fiscal Year 2001; Project Start 01-AUG-1994; Project End 31-JUL-2002 Summary: (Investigator's abstract) The long-term goal of this research program is to use gene-targeting and gene-transfer technologies in mice to directly test the following general hypothesis: hemostatic factors are critical in the progression and pathobiology a wide spectrum of diseases, including atherosclerosis, cancer, fibrotic lung disease, sickle cell disease, and other diseases associated with acute or chronic tissue injury. The specific objective of this research plan is to directly test the hypothesis that two key hemostatic factors, fibrinogen (Fib) and plasminogen (Plg), are important in the progression of vessel wall disease. A substantial amount of indirect evidence has pointed to a critical role of hemostatic factors in the early progression of atherosclerotic disease that generally precedes and predisposes to myocardial infarction and stroke, including the presence of copious amounts of fibrin(ogen) and fibrin degradation products within early lesions, high local expression of procoagulants and fibrinolytic system components, epidemiological identification of specific hemostatic factors as risk factors for coronary artery disease, and the incorporation of mural thrombi into advanced plaques. The recent generation of gene-targeted mouse lines predisposed to atherosclerosis as a consequence of selected deficiencies in apolipoproteins or their receptors, coupled with the availability of mice with selected deficits in key hemostatic factors, has provided an opportunity to directly test the importance of specific coagulation and fibrinolytic factors in atherosclerosis in vivo. In Specific Aim 1 of this proposal, the progression of atherosclerotic disease will be quantitatively and qualitatively compared in LDLR-deficient and control C57B1/6 mice that either retain or lack Fib and Plg. Age, diet, and gender will be examined as independent variables in these studies. The mechanistic role of fibrin(ogen) in the acceleration of atherosclerosis observed in Plg-deficient mice will be determined in Specific Aim 2 by detailed analysis of atherosclerotic disease in mice with single and combined deficiencies in those hemostatic factors. In Specific Aim 3, the impact of Fib and Plg deficiencies on neointima formation following chronic inflammatory challenge will be evaluated. The proposed studies will provide a more detailed understanding of the role of specific coagulation/fibrinolytic factors in vascular disease and could ultimately lead to new and valuable therapeutic strategies for the prevention and treatment of vascular disorders causing life-threatening arterial occlusion.

Project Title: HIV PROTEASE INHIBITORS AND ATHEROSCLEROSIS Principal Investigator & Institution: Smart, Eric J.; Professor; Physiology; University of Kentucky 109 Kinkead Hall Lexington, Ky 40506 Timing: Fiscal Year 2002; Project Start 15-APR-2002; Project End 31-MAR-2007 Summary: (provided by applicant) We hypothesize that HIV protease inhibitors alter macrophage class B scavenger receptor-dependent uptake and efflux of cholesterol thereby promoting the formation of lipid-laden macrophages and atherosclerotic lesions. A major drawback to the use of HIV protease inhibitors is that they promote the development of dyslipidemia, which is an established risk factor for the development of atherosclerosis. Numerous reports have suggested a causal link between protease inhibitor therapy and atherosclerosis; however, this has not been unequivocally demonstrated in a large-scale clinical trial. The dyslipidemia, which is primarily an increase in triglycerides, is unlikely to completely account for the development of atherosclerotic lesions in HIV patients because atherosclerosis is a multifactorial disease that is not controlled by a single factor. Our preliminary data demonstrate that HIV protease inhibitors have direct effects on macrophages, which are critical cellular

41
mediators in atherosclerotic lesion development. The generation of lipid-laden macrophages is a key event in atherogenesis and is thought to be due, in part, to unregulated uptake of modified lipoproteins. Such aberrant cholesterol accumulation is influenced by the functions of the class B scavenger receptors, SR-BI and CD36. Both receptors are found in atherosclerotic lesions and on macrophages. In addition, both receptors can mediate the uptake of lipoprotein cholesterol and the efflux of cellular cholesterol. Our preliminary data demonstrate that peritoneal macrophages isolated from LDL receptor null mice given the HIV protease inhibitors, amprenavir, indinavir, or ritonavir, contain more SR-BI and CD36 than aged-matched controls. In addition, all three protease inhibitors increased SR-BI and CD36 levels in THP-1 cells, our macrophage cell model system. The protease inhibitors also increased the cellular cholesterol content in both the in vivo and in vitro model systems, which is consistent with our hypothesis. Importantly, mice given amprenavir, indinavir, or ritonavir had significantly more atherosclerotic lesions than control mice. We will test two Specific Aims. Aim 1 : To determine the effects of HTV protease inhibitors on SR-BI and CD36 dependent cholesterol uptake and efflux. Aim 2: To determine the leukocyte (i.e., macrophages, etc.) specific effects of HIV protease inhibitors on atherosclerotic lesion formation in LDL receptor null mice that have been transplanted with bone marrow from SR-BI x LDLR and CD36 x LDLR null mice.

Project Title: HYPERTENSION / ATHEROSCLEROSIS PARADIGMS Principal Investigator & Institution: Herrera, Victoria L.; Profesor of Medicine; Medicine; Boston University Medical Campus 715 Albany St, 560 Boston, Ma 02118 Timing: Fiscal Year 2001; Project Start 15-AUG-1999; Project End 31-JUL-2003 Summary: Clinical and experimental data demonstrate unequivocally that hypertension accelerates atherosclerosis. This is an intriguing pathogenic phenomenon since the interaction is quite unambiguous for two complex diseases marked by clinical and genetic heterogeneity. Currently, the mechanisms underlying this interaction have not been elucidated. Strategic animal models are needed to mechanistically dissect pathogenesis. We have developed a transgenic hyperlipidemia- genetic hypertensive rat model by hepatic over-expression of human cholesteryl ester transfer protein (hCETP) in Dahl salt-sensitive (S) rats. Transgene high copy number in Tg[hCETP]53 Dahl S rats elicits aortic, coronary and intramyocardial atherosclerotic lesions and decreased life spans compared with no lesions in non-transgenic Dahl S controls and minor medial changes in Tg[hCETP]25 Dahl S rats with transgene moderate copy number. In this research proposal, we will investigate whether synergistic decrease of NO activity induced by both hypertension and atherosclerosis results in enhanced activated endothelial molecular and cellular changes which are then differentially amplified. as enhanced pro-inflammatory and pro-thrombotic changes leading to progressive vascular disease. The following specific aims will be studied: 1) Determined whether the endothelium of hypertensive, markedly hyperlipidemic Tg[hCETP]53 Dahl S rats exhibit exaggerated endothelial cell activation (marked by enhanced and/or sustained upregulation of ICAM-1 and P-selectin gene expression and increased monocyte adhesion compared with control age-matched normotensive, markedly hyperlipidemic Tg[hCETP]53 Dahl salt-resistant (R) male rats, and control non-transgenic age-matched hypertensive, normolipidemic Dahl S rats. 2) Determine whether exaggerated activation results in amplified dysregulation through enhanced pro-inflammatory response (marked by increased TNF-alpha expression and increased NF-kappaB activation in endothelial cells, macrophages) and/or pro-thrombotic response (marked by tissue

factor TF expression in endothelial cells, macrophages, intimal smooth muscle cells)-distinct from corresponding arteries in control normotensive, markedly hyperlipidemic Tg[hCETP]53 Dahl R rats as well as in control hypertensive, normo-lipidemic Dahl S rats. 3) Define the hierarchical relationship of hypertension hyperlipidemia and decreased NO activity on the acceleration of atherosclerosis by determining which manipulation, high salt diet, Western Type Diet, or NO-inhibitor L-NA treatment will cause Tg[hCETP]25 Dahl S rats to exhibit similar atherosclerotic lesion phenotype similar to Tg[hCETP]53 Dahl S rats. 4) Define the mechanistic role of endothelial NO pathway in the interaction of hypertension and atherosclerosis; sufficient versus essential but not sufficient versus modifying but not essential by early, mid-point, and late-onset L-arginine treatment of Tg[hCETP]53 Dahl S rats and determine whether the acceleration of atherosclerosis by hypertension is differentially attenuated, if not significantly resolved. This research proposal will provide key information on mechanisms that underlie the acceleration of atherosclerosis by hypertension which will identify new strategies for intervention.

Project Title: IMMUNOBIOLOGY OF APOLIPOPROTEIN E Principal Investigator & Institution: Curtiss, Linda K.; Professor; Scripps Research Institute 10550 N Torrey Pines Rd La Jolla, Ca 920371000 Timing: Fiscal Year 2001; Project Start 01-DEC-1988; Project End 31-MAR-2003 Summary: Coronary artery disease, the major manifestation of atherosclerosis, is the leading cause of death in the Western world. In spite of this striking impact, the pathogenesis of atherosclerosis is till poorly understood. Controversy exists regarding the participation of innate immunity involving macrophages. (Mphi) and natural killer (NK) cells versus antigen-specific acquired immunity involving lymphocytes. Mphi predominate in atherosclerotic lesions. NK cells, although smaller in number a present as well. Furthermore the T lymphocytes that participate in acquired immunity are frequently observed in lesions and have been demonstrated to modulate lesion progression. This proposal will address directly the participation of the innate inflammatory and acquired immune responses in vivo. To demonstrate the participation of NK cells in atherosclerosis resulting from moderate as well as profound hypercholesterolemia, we will combine the use of well characterized mouse models of atherosclerosis with inbred strains of mice that are deficient in T and B cell and / or NK cell function. Our first aim is to detail the frequency and the kinetics of NK cell and T cell localization within lesions of apolipoprotein E-deficient (apo E -/-) and low density lipoprotein receptor-deficient (LDL-R-/-) mice with both moderate and severe hypercholesterolemia. This aim will determine the degree to which NK cells and T lymphocytes influence the progression of ahteroma and reveal whether T and NK cell cytokine expression are responsible for the characteristic pathology of the disease. Because the participation of NK cells will be examined in both immune-competent as well as severely immune-deficient animals, these studies will provide valuable information on the participation of NK cells will be examined in both immunecompetent as well as severely immune-deficient animals, these studies will provide valuable information on the participation of both innate and acquired immune responses in atherosclerosis. Our second aim will identify if NK cell and T lymphocyte function within atherosclerotic lesions are influenced by locally produced Mphi apo E. WE have determined that macrophage-derived apo E plays a protective role within the lesions o LDL-r-/- mice and this aim will reveal if regulation of NK cell and/or T cell function is a mechanism by which apo E bestows this protection. The successful

completion of these studies will provide critical data about the role of T cells and/or NK cells in arherosclerosis that will aid in the development of new treatment strategies to alter the course of atherosclerosis in humans. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: IRAS FAMILY STUDY--GENETICS OF INSULIN RESISTANCE Principal Investigator & Institution: Bergman, Richard N.; Physiology and Biophysics; University of Southern California 2250 Alcazar Street, Csc-219 Los Angeles, Ca 90033 Timing: Fiscal Year 2001; Project Start 15-AUG-1999; Project End 31-JUL-2003 Summary: Insulin resistance is an important risk factor for atherosclerosis. Insulin resistance varies widely within populations, and substantial evidence indicates that much of this variation can be attributed to genetic sources. Visceral adiposity, another important atherosclerosis risk factor, is strongly correlated with insulin resistance, and this trait also appears to be under substantial genetic control. The overall goals of the proposed research project are to: 1) identify the genetic determinants of insulin resistance and visceral adiposity; and 2) determine the extent to which insulin resistance visceral adiposity, and metabolic cardiovascular disease risk factors share common genetic influences. To address these goals, we will enroll 160 families of AfricanAmerican and Hispanic background who are participating in the Insulin Resistance Atherosclerosis Study (ERAS). Approximately 1280 additional family members will be recruited. Insulin resistance will be measured using the frequently sampled intravenous glucose tolerance test, and visceral adiposity will be measured using computed tomography. A panel of other metabolic cardiovascular disease risk factors will also be assessed. A panel of 370 microsatellite markers will be genotyped from DNA, and a genome-wide scan will be performed to detect chromosomal regions containing loci that influence phenotypic variation. We will then saturate the regions of linkage identified in these analyses with additional markers and will then perform linkage disequilibrium analyses in effort to localize further the putative loci. The organization of this study will be similar to that of IRAS, with three clinical centers, a coordinating center, a central laboratory and a genetic laboratory. This center at the University of Southern California will be responsible for performing and coordinating laboratory measurements, as well as for analysis of insulin sensitivity and other metabolic parameters. This project will contribute substantially to our understanding of the genetic determinants of insulin sensitivity, and consequently to risk of atherosclerosis.

Project Title: L-ARGININE METABOLISM AND CORONARY VASCULAR FUNCTION Principal Investigator & Institution: Kuo, Lih; Professor; Medical Physiology; Texas A&M University Health Science Ctr College Station, Tx 778433578 Timing: Fiscal Year 2001; Project Start 01-APR-1997; Project End 31-MAR-2003 Summary: Atherogenesis is a complex process that appears to be initiated by alterations of endothelium. An elevated level of plasma low-density lipoproteins (LDL) is thought to be responsible for the development of atherosclerosis because the characteristics of LDL-induced endothelium dysfunction are very similar to those observed in hypercholesterolemic and atherosclerotic subjects. Indeed, exposure of normal large coronary arteries to pathological concentrations of LDL inhibits endotheliumdependent vasorelaxation within minutes. However, it is unclear whether coronary microvessels ( T) and hepatic lipase (LIPC -514C > T) promoter variants affects glucose tolerance in young adults.

These are listed at www.ClinicalTrials.gov.
152 Atherosclerosis
Purpose - Excerpt: High cholesterol levels are common in people with Systemic Lupus Erythematosus (SLE). Atorvastatin is a drug that reduces cholesterol levels. This study will test whether atorvastatin can reduce cholesterol levels in children with SLE. Phase(s): Phase III Study Type: Interventional Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00065806 •
Cardiovascular Evaluation of Patients with High Cholesterol and Normal Volunteers Condition(s): Atherosclerosis; Hypercholesterolemia Study Status: This study is currently recruiting patients. Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) Purpose - Excerpt: Homozygous familial hypercholesterolemia is a rare inherited disease of metabolism. It occurs in less than 1 in 1 million people within the United States. Patients with the disease are typically children and young adults who develop heart disease early in life. Children less than age 5 years with this disease have suffered heart attacks and death. The normal process that removes cholesterol particles from the blood stream does not work in patients with this disease. It causes cholesterol to buildup in the arteries and leads to hardening of the arteries (atherosclerosis). The goal of this study is to detect and measure atherosclerosis in these patients before it becomes permanent and potentially life threatening. Patients with this disease can participate in this study. Researchers plan to evaluate patients with homozygous familial hypercholesterolemia using new and standard methods for detecting atherosclerosis. Researchers plan to use information gathered during this study to develop new, promising treatments such as liver transplantation and gene therapy. Study Type: Observational Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00001204
•
Effect of High Dose Vitamin E on Carotid Atherosclerosis Condition(s): Cardiovascular Diseases Study Status: This study is currently recruiting patients.

Lipoprotein Metabolism in Normal Volunteers and Patients with High Levels of Lipoproteins Condition(s): Abetalipoproteinemia; Atherosclerosis; Healthy; Inborn Errors Lipid Metabolism Study Status: This study is currently recruiting patients. Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) Purpose - Excerpt: Researchers plan to study the fat-rich particles, called lipoproteins, which circulate in the blood. This study is designed to improve understanding of normal, as well as abnormal, lipoprotein metabolism and the role it plays in the development of hardening of the arteries (atherosclerosis). Patients participating in this study will receive injections of lipoproteins or apolipoproteins (the protein component of lipoproteins) that have been isolated and purified. These lipoproteins will be labeled with small amounts of radioactive material and sterilized before they are injected into the patient. Patients participating in the study will be required to have blood samples taken, and provide urine samples throughout the course of the study. In addition, patient will be required to follow a specially formulated diet. Patients will be weighed throughout the course of the study. Study Type: Observational Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00001154
•
Magnetic Resonance Angiography (MRA) for the Diagnosis of Atherosclerosis Condition(s): Atherosclerosis Study Status: This study is currently recruiting patients. Sponsor(s): Warren G Magnuson Clinical Center (CC) Purpose - Excerpt: Magnetic Resonance Angiography (MRA) is a method used to evaluate arteries and veins without the use of invasive catheters or x-rays (radiation). MRA technique has been continuously improving and has become more accurate at diagnosing problems of narrowing in blood vessels. However, MRA has a difficult time detecting narrowing in small blood vessels, limiting its use to large arteries. The purpose of this study is to recruit patients diagnosed with or suspected of having, atherosclerosis (hardening of the arteries) to participate in a series of new state-of-the-art diagnostic tests using MRA. This study is a combined effort between the National Institutes of Health (NIH), Uniformed Services University of the Health Sciences (USUHS), and General Electric Medical Services and is supported a Cooperative Research Agreement is to (CRADA). The goal of this study is to improve MRA to the point that it can reliably replace diagnostic x-ray catheter angiography in the evaluation of patients with atherosclerosis.

Comparison of Asymptomatic Carotid Atherosclerosis Between Frequent and Infrequent Blood Donors Condition(s): Carotid Atherosclerosis; Myocardial Infarction Study Status: This study is completed. Sponsor(s): Warren G Magnuson Clinical Center (CC) Purpose - Excerpt: Iron has been proposed to contribute to atherogenesis in humans by facilitating the oxidation of lipoproteins. This observational study will evaluate the association between frequency of blood donation - expected to be associated with relatively reduced body iron stores in frequent donors - and carotid atherosclerosis. The primary outcome variable will be whether the presence and extent of asymptomatic carotid atherosclerosis as measured by ultrasound is greater in infrequent (less than or equal to 1 donations/year greater than or equal to 5 years) vs. frequent (greater than or equal to 4 donations/year greater than or equal to 5 years) blood donors. Body iron stores, lipid and hemostatic parameters, nitric oxide formation, inflammatory parameters, and markers of vascular oxidative stress will be analyzed as secondary outcome measures. Laboratory analysis and ultrasound testing will be performed blinded to the patient's phlebotomy and iron status. Sixty frequent (n=40 males greater than 40 y/o, n=20 females greater than 50 y/o) and 60 infrequent (n=40 males greater than 40 y/o, n=20 females greater than 50 y/o) blood donors will be recruited for this study from the Department of Transfusion Medicine, W. G. Magnuson Clinical Center. All donors will be assessed for study eligibility and cardiovascular risks during the screening visit.

Comparison of Magnetic Resonance Angiography and Standard Angiography in Diagnosing Atherosclerosis Condition(s): Atherosclerosis Study Status: This study is completed. Sponsor(s): Warren G Magnuson Clinical Center (CC) Purpose - Excerpt: This study will evaluate ways to improve magnetic resonance angiography (MRA) for diagnosing atherosclerosis (hardening and narrowing of the arteries). MRA is a new method for looking at arteries and veins without standard angiography, which requires inserting a catheter into a blood vessel, injecting a contrast material, and obtaining X-ray images. Current MRA techniques, however, do not depict the lumen (cavity) of small vessels well enough to accurately determine the extent of their narrowing. This study will test image processing methods with the eventual goal of improving MRA accuracy to the point that it can replace X-ray catheter angiography for diagnosing atherosclerotic disease. Patients with atherosclerosis who have had conventional angiography at Suburban Hospital in Bethesda, MD, may be considered for this study. They will be screened with a brief history and physical examination, and those enrolled will have a MRA scan within 72 hours of their conventional angiogram. For this procedure, a catheter is placed in a vein in the patient's arm and the patient lies on a table that slides into a magnetic resonance imaging (MRI) scanner-a large donutshaped machine with a magnetic field. Surface coils-flexible, padded antennae used to improve the quality of the pictures-are wrapped around the patient's legs. At times during the scan, the patient is asked to hold his or her breath for several seconds, and a contrast material called gadolinium is injected through the catheter in the vein. This substance enhances the images of blood flow in the vessels. The procedure generally takes about an hour and a half, although the actual imaging takes only a small part of that time.

Effects of Hormone Replacement Therapy on Inflammation and Stiffening of Artery Walls Condition(s): Atherosclerosis; Healthy; Vascular Disease Study Status: This study is completed. Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) Purpose - Excerpt: This study will determine the effects of hormone replacement therapy (estrogen alone or estrogen and progesterone) on the walls of arteries in postmenopausal women. Inflammation and stiffness of artery walls are two risk factors for atherosclerosis-deposits of fatty substances (plaques) that can block the vessel, causing a heart attack or stroke. Estrogen raises the levels of certain substances in the blood that cause vessel inflammation and lowers the levels of others. This study will measure the net effects of estrogen on artery wall inflammation and stiffness. Postmenopausal women in good health may participate in this study. Volunteers will be screened for eligibility with a complete medical history, heart examination, and blood tests. Participants will be randomly assigned to receive either: 1) hormone therapy (estradiol 2 mg daily alone for women who have had a hysterectomy or estradiol plus micronized progesterone 200 mg daily for women with an intact uterus); or 2) placebo (look-alike pills that contain no active drug). Women in both groups will take pills for 3 months, then no pills for 1 month, and then will crossover to the alternate therapy for 3 months (i.e., those in the original placebo group will take hormones, and those in the hormone group will take placebo). At the end of each 3-month treatment period, participants will undergo the following procedures to assess blood vessel inflammation and stiffness: 1. Blood tests - 60 cc (about 2 ounces) of blood will be drawn to measure levels of hormones, cholesterol, and substances in the blood that indicate inflammation of the vessels. 2. Ultrasonography - an ultrasound probe will be applied gently on the neck to image the right and left carotid arteries (arteries in the neck that lead to the brain). During the procedure, the heart's electrical activity will also be monitored with an electrocardiogram and a blood pressure cuff will be wrapped around the arm to obtain blood pressure measurements every 5 minutes. 3. Magnetic resonance imaging (MRI) - Images of the carotid arteries are taken while the volunteer lies on a table in a narrow cylinder containing a magnetic field. A padded sensor called an MRI coil is placed over the neck and earplugs are placed in the ears to muffle the loud noise of the machine during scanning. During the second half of the exam, gadolinium is injected through a catheter (thin, flexible tube) inserted into a vein. Gadolinium is a contrast agent that is used to brighten the scan images. Information from this study will increase knowledge about the effects of estrogen on vessel wall inflammation. As such, it may be

Effects of Hormone Therapy on the Immune Systems of Postmenopausal Women with Chronic Infections Condition(s): Atherosclerosis; Chlamydia Infections; Cytomegalovirus Infections; Pneumonia, Bacterial; Postmenopause Study Status: This study is completed. Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) Purpose - Excerpt: Hardening of the arteries (atherosclerosis) and heart disease are much more common in men than in women. However, as women grow older, especially after menopause the incidence of atherosclerosis and heart disease increases. These findings suggest that estrogen may be protective and help in preventing heart disease. Studies of large groups of post-menopausal women suggest that hormone replacement therapy (therapy that includes estrogen) reduces the risk of heart disease. Estrogen causes favorable changes in particles that carry cholesterol in the blood stream and improves function of blood vessels. Estrogen may also stimulate the immune system's ability to fight off infections that may lead to or contribute to atherosclerosis. Researchers believe two specific infectious agents (Chlamydia pneumoniae and human cytomegalovirus) may cause damage to the lining of blood vessels resulting in inflammation and the development of atherosclerosis. The purpose of this study is to determine if estrogen treatment can change how the immune system responds to chronic infections, by Chlamydia pneumoniae and human cytomegalovirus, in postmenopausal women.

Magnetic Resonance Imaging to Detect Blood Vessel Inflammation in Patients Undergoing Peripheral Balloon Angioplasty Condition(s): Atherosclerosis; Peripheral Vascular Disease Study Status: This study is completed. Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) Purpose - Excerpt: This study will examine the use of magnetic resonance imaging (MRI) in detecting blood vessel inflammation. The results of this study may later be applied to diagnosing inflammation of arteries in patients with atherosclerosis, predicting disease progression in these patients, and guiding therapy. Patients with peripheral artery disease (for example, blockage of a leg artery) undergoing balloon angioplasty at Suburban Hospital in Bethesda, Maryland, may be eligible to participate in this study. Because this procedure, which opens blocked arteries, can cause inflammation in the vessel wall, it affords an opportunity for studying MRI detection of such inflammation. Study candidates will be screened with a medical history and physical examination. Participants will have a MRI scan and blood drawn at Suburban Hospital before the angioplasty and again either 1 to 3 days or 2 weeks after the procedure. Before the MRI scan is begun, a catheter (a thin plastic tube) is inserted in an arm vein and 90 milliliters (about 3 ounces) of blood is drawn. The patient then lies on a table that slides into the MRI scanner-a large donut-shaped machine with a magnetic field. A flexible, padded sensor called an MRI coil is placed over the area to be imaged;

Potential Risk Factors for Stroke Condition(s): Carotid Atherosclerosis; Cerebrovascular Accident; Diabetes Mellitus; Hypercholesterolemia; Hypertension Study Status: This study is completed. Sponsor(s): National Institute of Neurological Disorders and Stroke (NINDS) Purpose - Excerpt: Early studies have shown that the immune system may play a role in the development of strokes. Conditions such as high blood pressure, high cholesterol, diabetes, and old age can activate the immune system and increase the risk of developing hardening of the arteries (atherosclerosis) and damaged blood vessels. Researchers will attempt to characterize factors that may contribute to atherosclerosis and stroke by measuring certain components of the immune system, cytokines and leukocyte activation. Measurements will be taken from patients that are considered to be stroke prone and from patients without risk factors for the development of stroke. Researchers will measure the immune system components at the beginning of the study, at six months, and at the one-year completion of the study. The study will attempt to determine; I) If patients with risk factors for stroke have an increased activation of the immune system II) If patients with risk factors for stroke that are symptomatic have higher levels of immune system activation compared to patients who do not have symptoms III) If patients with increased activation of the immune system have accelerated hardening of the arteries (atherosclerosis) Phase(s): Phase I Study Type: Interventional Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00001368

Study of the Interaction Between the Cells Lining Blood Vessels and AngiotensinConverting Enzyme Condition(s): Atherosclerosis; Coronary Disease Study Status: This study is completed. Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) Purpose - Excerpt: The walls of blood vessels are lined by flat cells that are responsible for releasing substance(s) that control the activity of the blood vessel. These cells are referred to as the endothelium of the blood vessel. One of the substances released from the endothelium is called nitric oxide (NO). This substance functions to keep blood vessels relaxed and to prevent blood from clotting inside the vessels. Studies done by researchers in the Cardiology Branch of the National Heart, Lung and Blood Institute have shown that nitric oxide activity may be lower in patients with hardening of the arteries (atherosclerosis) and risk factors for atherosclerosis. Another substance released by the cells of the endothelium is called bradykinin. It functions to stimulate the production of nitric oxide. Therefore bradykinin is also responsible for the relaxation and widening of blood vessels. An enzyme found in the blood called angiotensinconverting enzyme (ACE) inactivates baradykinin and thereby decreases the production of nitric oxide. The activity of ACE is determined by genetics and is different in each person. Medications that block ACE (ACE-inhibitors) may be useful for patients with high levels of ACE activity. This study is designed to determine; 1. The role of bradkinin in stimulating the production of nitric oxide 2. Whether ACE-inhibitors improve blood vessel relaxation caused by bradykinin 3. Whether ACE-inhibitors improve abnormal blood vessel relaxation 4. Whether ACE-inhibitors and bradykinin affect blood clotting 5. Whether blood vessel response to ACE-inhibitor and bradykinin depends on the patients genetic make-up Study Type: Observational Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00001461

Study Status: This study is completed. Sponsor(s): National Institute of Allergy and Infectious Diseases (NIAID) Purpose - Excerpt: The purpose of this study is to see if there is a difference in the thickness of the carotid artery (the large artery in the neck) among HIV-positive participants taking protease inhibitors (PIs), HIV-positive participants not taking PIs, and HIV-negative participants. This study will also look at how the thickness in the carotid artery might change in these participants over time. The intima-media thickness (IMT) test uses sound waves to measure the thickness of the carotid artery. Studies have shown that this test may be able to predict a person's risk for heart disease. This study will use the IMT test to see if anti-HIV treatment and HIV infection affect a patient's risk of getting atherosclerosis (hardening of the arteries).

CHAPTER 6. PATENTS ON ATHEROSCLEROSIS Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.9 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “atherosclerosis” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on atherosclerosis, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Atherosclerosis By performing a patent search focusing on atherosclerosis, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We will tell you how to obtain this information later in the chapter. The following is an 9Adapted

1, 3-bis-(substituted-phenyl)-2-propen-1-ones and their use to treat VCAM-1 mediated disorders Inventor(s): Hoong; Lee K. (Suwanee, GA), Meng; Charles Q. (Alpharetta, GA), Ni; Liming (Duluth, GA), Sikorski; James A. (Alpharetta, GA) Assignee(s): Atherogenics, Inc. (Alpharetta, GA) Patent Number: 6,608,101 Date filed: June 20, 2001 Abstract: It has been discovered certain 1,3-bis-(substituted-phenyl)-2-propen-1-ones, including compounds of formula (I) inhibit the expression of VCAM-1, and thus can be used to treat a patient with a disorder mediated by VCAM-1. Examples of inflammatory disorders that are mediated by VCAM-1 include, but are not limited to arthritis, asthma, dermatitis, cystic fibrosis, post transplantation late and chronic solid organ rejection, multiple sclerosis, systemic lupus erythematosis, inflammatory bowel diseases, autoimmune diabetes, diabetic retinopathy, rhinitis, ischemia-reperfusion injury, postangioplasty restenosis, chronic obstructive pulmonary disease (COPD), glomerulonephritis, Graves disease, gastrointestinal allergies, conjunctivitis, atherosclerosis, coronary artery disease, angina and small artery disease. Excerpt(s): The present invention includes novel heteroaryl or heterocyclic 1,3-bis(substituted-phenyl)-2-propen-1-ones as well as methods and compositions for the treatment of disorders mediated by VCAM-1 or MCP-1 and for the treatment of inflammatory disorders generally that include the administration of a 1,3-bis(substituted-phenyl)-2-propen-1-one that has at least one phenyl substituent that is an aryl, heteroaryl or heterocyclic moiety. Adhesion of leukocytes to the endothelium represents a fundamental, early event in a wide variety of inflammatory conditions, autoimmune disorders and bacterial and viral infections. Leukocyte recruitment to endothelium is mediated in part by the inducible expression of adhesion molecules on the surface of endothelial cells that interact with counterreceptors on immune cells. Endothelial cells determine which types of leukocytes are recruited by selectively expressing specific adhesion molecules, such as vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1), and E-selectin. VCAM-1 binds to the integrin VLA-4 expressed on lymphocytes, monocytes, macrophages, eosinophils, and basophils but not neutrophils. This interaction facilitates the firm adhesion of these leukocytes to the endothelium. VCAM-1 is an inducible gene that is not expressed, or expressed at very low levels, in normal tissues. VCAM-1 is upregulated in a number of inflammatory diseases, including arthritis, asthma, dermatitis, psoriasis, cystic fibrosis, post transplantation late and chronic solid organ rejection, multiple sclerosis, systemic lupus erythematosis, inflammatory bowel diseases, autoimmune diabetes, diabetic retinopathy, rhinitis, ischemia-reperfusion injury, post-angioplasty restenosis, chronic obstructive pulmonary disease (COPD), glomerulonephritis, Graves disease, gastrointestinal allergies, conjunctivitis, atherosclerosis, coronary artery disease, angina and small artery disease. Coronary heart disease (CHD), primarily as a result of atherosclerosis, remains the leading cause of death in industrialized countries. Atherosclerosis is a disease characterized by vascular inflammation, deposition of lipids in the arterial vessel wall and smooth muscle cell proliferation resulting in a narrowing of the vessel passages. In advanced stages of the disease atherosclerotic lesions can become unstable resulting in plaque rupture, thrombosis, myocardial infarction and
Patents 175
ischemic heart disease. It is now well accepted that the initiating events in atherosclerosis are local injury to the arterial endothelium that results in the induction of VCAM-1 and recruitment of mononuclear leukocytes that express the integrin counterreceptor, VLA-4, (O'Brien, et al., J. Clin. Invest., 92: 945-951, 1993). Subsequent conversion of leukocytes to foamy macrophages results in the synthesis of a wide variety of inflammatory cytokines, growth factors, and chemoattractants that help propagate formation of the mature atheromatous plaque by further inducing endothelial activation, leukocyte recruitment, smooth muscle cell proliferation, and extracellular matrix deposition. Pharmacological inhibition of VCAM-1 expression has been shown to inhibit atherosclerosis in several animal models (Sundell et al., Circulation, 100: 42, 1999). A monoclonal antibody against VCAM-1 has also been shown to inhibit neointimal formation in a mouse model of arterial wall injury (Oguchi, S., et al., Arterioscler. Thromb. Vasc. Biol., 20: 1729-1736, 2000). Web site: http://www.delphion.com/details?pn=US06608101__ •

(Waterford, CT), Wester; Ronald T. (Ledyard, CT) Assignee(s): Pfizer Inc. (New York, NY) Patent Number: 6,586,448 Date filed: October 10, 2000 Abstract: Cholesteryl ester transfer protein inhibitors, pharmaceutical compositions containing such inhibitors and the use of such inhibitors to elevate certain plasma lipid levels, including high density lipoprotein-cholesterol and to lower certain other plasma lipid levels, such as LDL-cholesterol and triglycerides and accordingly to treat diseases which are exacerbated by low levels of HDL cholesterol and/or high levels of LDLcholesterol and triglycerides, such as atherosclerosis and cardiovascular diseases in some mammals, including humans. Excerpt(s): This invention relates to cholesteryl ester transfer protein (CETP) inhibitors, pharmaceutical compositions containing such inhibitors and the use of such inhibitors to elevate certain plasma lipid levels, including high density lipoprotein (HDL)-cholesterol and to lower certain other plasma lipid levels, such as low density lipoprotein (LDL)cholesterol and triglycerides and accordingly to treat diseases which are affected by low levels of HDL cholesterol and/or high levels of LDL-cholesterol and triglycerides, such as atherosclerosis and cardiovascular diseases in certain mammals (i.e., those which have CETP in their plasma), including humans. Atherosclerosis and its associated coronary artery disease (CAD) is the leading cause of mortality in the industrialized world. Despite attempts to modify secondary risk factors (smoking, obesity, lack of exercise) and treatment of dyslipidemia with dietary modification and drug therapy, coronary heart disease (CHD) remains the most common cause of death in the U.S., where cardiovascular disease accounts for 44% of all deaths, with 53% of these associated with atherosclerotic coronary heart disease. Risk for development of this condition has been shown to be strongly correlated with certain plasma lipid levels. While elevated LDL-C may be the most recognized form of dyslipidemia, it is by no means the only significant lipid associated contributor to CHD. Low HDL-C is also a known risk factor for CHD (Gordon, D. J., et al.,: "High-density Lipoprotein Cholesterol and Cardiovascular Disease", Circulation, (1989), 79: 8-15).

Androgen receptor modulators and methods for use thereof Inventor(s): Breslin; Michael J. (Drexel Hill, PA), Duggan; Mark E. (Schwenksville, PA), Halczenko; Wasyl (Lansdale, PA), Harada; Shun-Ichi (Ambler, PA), Hutchinson; John H. (La Jolla, CA), Rodan; Gideon A. (Bryn Mawr, PA), Sahoo; Soumya P. (Old Bridge, NJ), Schmidt; Azriel (Bryn Mawr, PA), Towler; Dwight A. (Brentwood, MO) Assignee(s): Merck & Co., Inc. (Rahway, NJ) Patent Number: 6,645,974 Date filed: July 25, 2002 Abstract: Compounds of structural formula (I) as herein defined are disclosed as useful in a method for modulating the androgen receptor in a tissue selective manner in a patient in need of such modulation, as well as in a method of agonizing the androgen receptor in a patient, and in particular the method wherein the androgen receptor is antagonized in the prostate of a male patient or in the uterus of a female patient and agonized in bone and/or muscle tissue. These compounds are useful in the treatment of conditions caused by androgen deficiency or which can be ameliorated by androgen administration, including: osteoporosis, periodontal disease, bone fracture, bone damage following bone reconstructive surgery, sarcopenia, frailty, aging skin, male hypogonadism, post-menopausal symptoms in women, atherosclerosis, hypercholesterolemia, hyperlipidemia, aplastic anemia and other hematopoietic disorders, pancreatic cancer, renal cancer, arthritis and joint repair, alone or in combination with other active agents. In addition, these compounds are useful as pharmaceutical composition ingredients alone and in combination with other active agents. Excerpt(s): Androgens play important roles in post-natal development that are most pronounced at adrenarche and pubarche. Androgen production promotes the musculoskeletal anabolism associated with the pubertal growth in both males and females. At puberty, ovarian and testicular androgens are responsible for pubertal hair, acne, and enhancement of libido. In males, exposure to 100-fold increased levels of endogenous androgens results in the gender dimorphism in bone mass, muscle mass (positive nitrogen balance), and upper body strength, and are required for normal sexual development (genitalia, spermatogenesis, prostate and seminal vesicle maturation). Delay in puberty decreases the peak bone mass achieved during adulthood. (Bhasin, S., et al., Eds. Pharmacology, Biology, and Clinical Applications of Androgens: Current Status and Future Prospects. Wiley-Liss, Inc.:New York, 1996). In women, natural menopause causes virtually complete loss of ovarian estrogen production and gradually reduces ovarian production of androgen by approximately 50%. The physiological consequences of reduced androgen production after menopause are evident in decreased energy and libido, and contribute significantly in many women to vasomotor symptoms. Decreased androgen output is also thought to contribute-along with declining pituitary growth hormone (GH) secretion and insulin derived growth factor 1 (IGF1) action--to age-dependent sarcopenia, negative nitrogen balance and loss of bone mass. (Vestergaard, et al., Effect of sex hormone replacement on the insulin-like growth factor system and bone mineral: a cross-sectional and longitudinal study in 595 perimenopausal women participating in the Danish Osteoporosis Prevention Study, J Clin Endocrinol Metab. 84:2286-90, 1999; and Bhasin, et al., Eds. Pharmacology, Biology, and Clinical Applications of Androgens: Current Status and
Patents 177
Future Prospects, Wiley-Liss, Inc.:New York. 1996). Postmenopausal osteoporosis results mainly from estrogen deficiency. However, many women who received estrogen replacement therapy still lose bone with age and develop age--related osteoporotic fractures (albeit at a lower rate than those taking estrogens), indicating that both estrogens and androgens play important roles for bone health in both women and men. The simultaneous decreases in bone mass, muscle mass and muscle strength increase the risk of falls and especially of hip fractures in both men and women >65 years of age. In fact, one-third of all hip fractures occur in men. The androgen receptor (AR) belongs to the nuclear receptor superfamily and controls transcription in a ligand dependent manner (Brinkman, et al., Mechanisms of androgen receptor activation and function, J. Ster. Biochem. Mol. Biol. 69, 307-313, 1999). Upon androgen binding, AR binds directly to specific DNA sequences present in the promoter region of androgen responsive genes, termed androgen response elements (AREs), to stimulate transcription. Using ARE-dependent transcription as a criterion, agents that bind to AR and stimulate AREdependent transcription can be classified as agonists, and those that bind to AR and suppress ARE-dependent transcription are classified as antagonists. A number of natural or synthetic androgen agonists have been used for treatment of musculoskeletal or hematopoietic disorders and for hormone replacement therapy. In addition, AR antagonists, such as flutamide or bicalutamide, are used for treatment of prostate cancer. However, clinical use of these androgen agonists or antagonists have been limited because of undesirable effects, such as hirsutism and prostate enlargement for agonists, and bone loss, fracture, gynecomastia and sarcopenia for antagonists. It would be useful to have available androgens with tissue selective agonistic activity, which increase bone formation and muscle mass but do not induce the virilization. A number of studies provide the proof of principle that androgens are osteoanabolic in women and men. Anabolic steroids, such as nandrolone decanoate or stanozolol, have been shown to increase bone mass in postmenopausal women. Beneficial effects of androgens on bone in post-menopausal osteoporosis are well-documented in recent studies using combined testosterone and estrogen administration (Hofbauer, et al., Androgen effects on bone metabolism: recent progress and controversies, Eur. J. Endocrinol. 140, 271-286, 1999). Combined treatment increased significantly the rate and extent of the rise in BMD (lumbar and hip), relative to treatment with estrogen alone. Additionally, estrogen-progestin combinations that incorporate an androgenic progestin (norethindrone) rather than medroxyprogesterone acetate yielded greater improvements in hip BMD. These results have recently been confirmed in a larger (N=311) 2 year, double blind comparison study in which oral conjugated estrogen (CEE) and methyltestosterone combinations were demonstrated to be effective in promoting accrual of bone mass in the spine and hip, while conjugated estrogen therapy alone prevented bone loss (A twoyear, double-blind comparison of estrogen-androgen and conjugated estrogens in surgically menopausal women: Effects on bone mineral density, symptoms and lipid profiles. J Reprod Med. 44(12):1012-20, 1999). Despite the beneficial effects of androgens in postmenopausal women, the use of androgens has been limited because of the undesirable virilizing and metabolic action of androgens. The data from Watts and colleagues demonstrate that hot flushes decrease in women treated with CEE+ methyltestosterone; however, 30% of these women suffered from significant increases in acne and facial hair, a complication of all current androgen pharmacotherapies (Watts, et al., Comparison of oral estrogens and estrogens plus androgen on bone mineral density, menopausal symptoms, and lipid-lipoprotein profiles in surgical menopause, Obstet. Gynecol. 85, 529-537, 1995). Moreover, the addition of methyltestosterone to CEE markedly decreased HDL levels, as seen in other studies. Thus, the current virilizing and metabolic side effect profile of androgen therapies provide a strong rationale for developing tissue selective androgen agonists for bone.

Benzimidazolone peptidometics as thrombin receptor antagonist Inventor(s): Maryanoff; Bruce E. (Forest Grove, PA), McComsey; David F. (Warminster, PA), White; Kimberly B. (North Wales, PA), Zhang; Han-Cheng (Lansdale, PA) Assignee(s): OrthoMcNeil Pharmaceutical, Inc. (Raritan, NJ) Patent Number: 6,630,451 Date filed: June 22, 2000 Abstract: The invention is directed to novel benzimidazolone peptidomimetic compounds which are useful as thrombin receptor antagonists for the treatment of diseases associated with thrombosis, restenosis, hypertension, heart failure, arrhythmia, inflammation, angina, stroke, atherosclerosis, ischemic conditions, Angiogenesis related disorders, cancer, and neurodegenerative disorders. Pharmaceutical compositions comprising the substituted benzimidazolone peptidomimetics of the present invention and methods of treating conditions mediated by the thrombin receptor are also disclosed. Excerpt(s): Thrombin is an important serine protease in hemostasis and thrombosis. One of the key actions of thrombin is cellular modulation via receptor activation. A functional human thrombin receptor (PAR-1), cloned by Coughlin in 1991 (T. -K. Vu, Cell 1991, 64, 1057), was found to be a member of the G-protein coupled receptor (GPCR) superfamily. The receptor activation putatively occurs by N-terminal recognition and proteolytic cleavage at the Arg-41/Ser-42 peptide bond to reveal a truncated N-terminus. This new N-terminus acting as a tethered ligand to recognize a site on the receptor, can trigger activation and signal transduction leading to platelet aggregation. Since 1991, three other protease-activated receptors with extensive homology to the thrombin receptor, "PAR-2" (S. Nystedt, Proc. Natl. Acad. Sci USA 1994, 91, 9208), "PAR-3" (H. Ishihara, Nature 1997, 386, 502), and "PAR-4" (W.-F. Xu, Proc. Natl. Acad. Sci USA 1998, 95, 6642), have been cloned. Thrombin receptor (PAR-1) specific antibody-induced blockade of the platelet thrombin receptor has shown efficacy against arterial thrombosis in vivo (J. J. Cook Circulation 1995, 91, 2961). Hence, antagonists of the thrombin receptor (PAR-1) are useful to block these proteaseactivated receptors and, as such, may be used to treat platelet mediated thrombotic disorders such as myocardial infarction, stroke, restenosis, angina, atherosclerosis, and ischemic conditions. The thrombin receptor (PAR-1) has also been identified on other cell types: endothelial, fibroblast, renal, osteosarcoma, smooth muscle, myocytes, tumor, and neuronal/glia. Thrombin activation of endothelial cells upregulates P-selectin to induce polymorphonuclear leukocyte adhesion--an inflammatory response of the vessel wall (Y. Sugama, J. Cell Biol. 1992, 119, 935). In fibroblasts, thrombin receptor (PAR-1) activation induces proliferation and transmission of mitogenic signals (D. T. Hung, J. Cell Biol. 1992, 116, 827). Thrombin has been implicated in osteoblast proliferation through its activation of osteoblast cells (D. N. Tatakis, Biochem. Biophys. Res. Commun. 1991, 174, 181). Thrombin has been implicated in the regulation and retraction of neurons (K. Jalink, J. Cell. Biol. 1992, 118, 411). Therefore, in this context, the antagonist compounds of this invention may also be useful against inflammation, osteoporosis, Angiogenesis related disorders, cancer, neurodegenerative disorders, hypertension, heart failure, arrhythmia, glomerulonephritis. The compounds of the present invention are a structurally novel class of benzimidazolone peptidomimetics represented by the general formula (I) below.

Benzopyrancarboxylic acid derivatives for the treatment of diabetes and lipid disorders Inventor(s): Boueres; Julia K. (Piscataway, NJ), Desai; Ranjit C. (Kendall Park, NJ), Koyama; Hiroo (Hoboken, NJ), Miller; Daniel J. (Edison, NJ), Sahoo; Soumya P. (Old Bridge, NJ) Assignee(s): Merck & Co., Inc. (Rahway, NJ) Patent Number: 6,645,997 Date filed: September 24, 2001 Abstract: A class of benzopyrancarboxylic acid derivatives comprises compounds that are potent agonists of PPAR alpha and/or gamma, and are therefore useful in the treatment, control or prevention of non-insulin dependent diabetes mellitus (NIDDM), hyperglycemia, dyslipidemia, hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, atherosclerosis, obesity, vascular restenosis, inflammation, and other PPAR alpha and/or gamma mediated diseases, disorders and conditions. Excerpt(s): The instant invention is concerned with benzopyrancarboxylic acids and related heterocyclic compounds and pharmaceutically acceptable salts and prodrugs thereof which are useful as therapeutic compounds, particularly in the treatment and prevention of Type 2 diabetes mellitus, often referred to as non-insulin dependent diabetes (NIDDM), of conditions that are often associated with this disease, and of lipid disorders. Diabetes refers to a disease process derived from multiple causative factors and characterized by elevated levels of plasma glucose or hyperglycemia in the fasting state or after administration of glucose during an oral glucose tolerance test. Persistent or uncontrolled hyperglycemia is associated with increased and premature morbidity and mortality. Often abnormal glucose homeostasis is associated both directly and indirectly with alterations of the lipid, lipoprotein and apolipoprotein metabolism and other metabolic and hemodynamic disease. Therefore patients with Type 2 diabetes mellitus are at especially increased risk of macrovascular and microvascular complications, including coronary heart disease, stroke, peripheral vascular disease, hypertension, nephropathy, neuropathy, and retinopathy. Therefore, therapeutical control of glucose homeostasis, lipid metabolism and hypertension are critically important in the clinical management and treatment of diabetes mellitus. There are two generally recognized forms of diabetes. In type 1 diabetes, or insulin-dependent diabetes mellitus (IDDM), patients produce little or no insulin, the hormone which regulates glucose utilization. In type 2 diabetes, or noninsulin dependent diabetes mellitus (NIDDM), patients often have plasma insulin levels that are the same or even elevated compared to nondiabetic subjects; however, these patients have developed a resistance to the insulin stimulating effect on glucose and lipid metabolism in the main insulinsensitive tissues, which are muscle, liver and adipose tissues, and the plasma insulin levels, while elevated, are insufficient to overcome the pronounced insulin resistance.

(571 Buena Vista, Moss Beach, CA 94038) Assignee(s): none reported Patent Number: 6,586,602 Date filed: January 14, 2002 Abstract: Disclosed are compounds which bind VLA-4. Certain of these compounds also inhibit leukocyte adhesion and, in particular, leukocyte adhesion mediated by VLA-4. Such compounds are useful in the treatment of inflammatory diseases in a mammalian patient, e.g., human, wherein the disease may be, for example, asthma, Alzheimer's disease, atherosclerosis, AIDS dementia, diabetes, inflammatory bowel disease, rheumatoid arthritis, tissue transplantation, tumor metastasis and myocardial ischemia. The compounds can also be administered for the treatment of inflammatory brain diseases such as multiple sclerosis. Excerpt(s): This invention relates to compounds which inhibit leukocyte adhesion and, in particular, leukocyte adhesion mediated by VLA-4. All of the above publications, patents and patent applications are herein incorporated by reference in their entirety to the same extent as if each individual publication, patent or patent application was specifically and individually indicated to be incorporated by reference in its entirety. Intercellular adhesion mediated by VLA-4 and other cell surface receptors is associated with a number of inflammatory responses. At the site of an injury or other inflammatory stimulus, activated vascular endothelial cells express molecules that are adhesive for leukocytes. The mechanics of leukocyte adhesion to endothelial cells involves, in part, the recognition and binding of cell surface receptors on leukocytes to the corresponding cell surface molecules on endothelial cells. Once bound, the leukocytes migrate across the blood vessel wall to enter the injured site and release chemical mediators to combat infection.

Breakers of advanced glycation endproducts Inventor(s): Rahbar; Samuel (Encino, CA) Assignee(s): City of Hope (Duarte, CA) Patent Number: 6,589,944 Date filed: July 27, 2000 Abstract: Advanced glycation endproducts (AGEs) have been implicated in the pathogenesis of a variety of debilitating diseases such as diabetes, atherosclerosis, Alzheimer's and rheumatoid arthritis, as well as in the normal aging process. Five compounds are here reported to be active in breaking AGE-protein cross-links. These compounds are L-bis-[4-(4-chlorobenzamido-phenoxyisobutyryl)cystine] (LR20); 4-(3,5-
Patents 181
dichlorophenylureido)phenoxyisobutyryl-1-amido-cyclohexane-1-carbox ylic acid (LR23); methylene bis [4,4'-(2-chlorophenylureido-phenoxyisobutyric acid)] (LR90); 5arninosalicylic acid (5-ASA); and metformin. These compounds may be used to reverse the debilitating effects of those diseases in which AGEs are formed. Excerpt(s): Glucose and other reducing sugars react and bind covalently to proteins, lipoproteins and DNA by a process known as non-enzymatic glycation. Glucose latches onto tissue proteins by coupling its carbonyl group to a side-chain amino group such as that found on lysine. Over time, these adducts form structures called advanced glycation endproducts (AGEs) (protein-aging). These cross-linked proteins stiffen connective tissue and lead to tissue damage in the kidney, retina, vascular wall and nerves. The formation of AGEs on long-lived connective tissue accounts for the increase in collagen cross-linking that accompanies normal aging which occurs at an accelerated rate in diabetes. The publications and other materials used herein to illuminate the background of the invention or provide additional details respecting the practice, are incorporated by reference, and for convenience are respectively grouped in the appended List of References. Advanced glycation endproducts (AGEs) have been implicated in the pathogenesis of a variety of debilitating diseases such as diabetes, atherosclerosis, Alzheimer's and rheumatoid arthritis, as well as in the normal aging process. Most recent researchers confirm a significant role of the accumulation of AGE cross-links in promoting the decreased cardiovascular compliance of aging (Asif et al., 2000). The process of AGE formation on arterial wall matrix proteins may be related to the development of atherosclerosis in many different ways, such as generation of free radicals (ROS) during the glycation process, inhibition of a normal network formation in collagen by AGE accumulation (Brownlee, 1994), and increased adhesion of monocytes (Gilcrease and Hoover, 1992).

Excerpt(s): The present invention relates to methods of treating cardiovascular diseases, and specifically relates to combinations of compounds, compositions, and methods for their use in medicine, particularly in the prophylaxis and treatment of hyperlipidemic conditions such as are associated with atherosclerosis, hypercholesterolemia, and other coronary artery disease in mammals. More particularly, the invention relates to ileal bile acid transporter (IBAT) inhibiting compounds. The invention also relates to fibric acid derivatives (fibrates). It is well-settled that hyperlipidemic conditions associated with elevated concentrations of total cholesterol and low-density lipoprotein (LDL) cholesterol are major risk factors for coronary heart disease and particularly atherosclerosis. Since high levels of LDL cholesterol increase the risk of atherosclerosis, methods for lowering plasma LDL cholesterol would be therapeutically beneficial for the treatment of atherosclerosis and other diseases associated with accumulation of lipid in the blood vessels. These diseases include, but are not limited to, coronary heart disease, peripheral vascular disease, and stroke. Atherosclerosis underlies most coronary artery disease (CAD), a major cause of morbidity and mortality in modern society. High LDL cholesterol (above about 180 mg/dl) and low HDL cholesterol (below 35 mg/dl) have been shown to be important contributors to the development of atherosclerosis. Other diseases or risk factors, such as peripheral vascular disease, stroke, and hypercholesterolemia are negatively affected by adverse HDL/LDL ratios.

Compositions and methods for improving vascular health Inventor(s): Chevaux; Kati A. (Seattle, WA), Dombroski; Amy (Stanhope, NJ), Jerome; Ralph (Blairstown, NJ), Schmitz; Harold H. (Branchburg, NJ) Assignee(s): Mars, Incorporated (McLean, VA) Patent Number: 6,610,320 Date filed: April 10, 2001 Abstract: This invention relates to compositions containing polyphenols, for example, cocoa polyphenols such as procyanidins, in combination with at least one cholesterol lowering agent, and methods for improving vascular health including treating and preventing atherosclerosis and cardiovascular disease. Excerpt(s): This invention relates to compositions containing polyphenols, for example, cocoa polyphenols such as procyanidins in combination with at least one cholesterol lowering agent and methods for improving vascular health including treating and preventing atherosclerosis and cardiovascular disease. Coronary artery disease, the primary form of cardiovascular disease (CVD), is the major cause of death in the United States today. Cerebrovascular disease is the third. The etiology of both coronary artery and cerebrovascular diseases is attributed to atherosclerosis. Through its clinical manifestations, atherosclerosis is the major cause of the more than one million heart attacks, approximately 400,000 strokes that occur each year and numerous vascular circulation problems. Many patients suffer from hypertension. A substantial body of evidence has established a causal relationship between hypercholesterolemia and premature atherosclerosis; the higher the levels of plasma cholesterol, the greater the risk of subsequent heart attack. (see e.g. Steinberg, D., JAMA 264:3047 (1990)). In the chain of events leading to atherosclerosis, it is believed that the initiating event is the formation of "fatty streaks" in carotid, coronary, and cerebral arteries, and in the aorta. These lesions include fatty deposits of cholesterol and cholesteryl ester that are found principally within the smooth muscle cells and macrophages of the intimal layer. The migration and proliferation of vascular smooth muscle cells play a crucial role in the pathogenesis of atherosclerosis following the initial deposition of lipid.

Dimer of molecular variant of apolipoprotein and processes for the production thereof Inventor(s): Abrahmsen; Lars (Stockholm, SE), Chmielewska; Joanna (Stockholm, SE), Franceschini; Guido (Milan, IT), Holmgren; Erik (Lidingo, SE), Lake; Mats (Lidingo, SE), Lind; Peter (Uppsala, SE), Nilsson; Bjorn (Sollentuna, SE), Sirtori; Cesare (Milan, IT) Assignee(s): Esperion Therapeutics, Inc. (Ann Arbor, MI) Patent Number: 6,617,134 Date filed: March 1, 1999 Abstract: Substantially pure dimers of Apolipoprotein AI-Milano (APO-AI-M/APO AIM) were isolated from plasma and characterized. Apolipoprotein AI-M dimer can also be produced in a recombinant Escherichia coli system. Pharmaceutical compositions comprising the ApoAI-AI-M/ApoAI-M are described. Patients with atherosclerosis or cardiovascular diseases can be treated with the dimer. Medicaments containing the dimer can also be used to prevent thrombosis in different clinical circumstances, both at the arterial and at the venous level. The dimer can also act as a prodrug for the monomer. Excerpt(s): The clear correlation between elevated levels of serum cholesterol and the development of coronary heart disease (CHD) has been repeatedly confirmed, based on epidemiological and longitudinal studies. The definition, however, of complex mechanisms of cholesterol transport in plasma, has allowed the recognition of a selective function of circulating lipoproteins in determining the risk for CHD. There are, in fact, four major circulating lipoproteins: chylomicrons (CM), very low density (VLDL), low density (LDL) and high density (HDL) lipoproteins. While CM constitute a short-lived product of intestinal fat absorption, VLDL and, particularly, LDL are responsible for cholesterol transport into tissues, including for example the arterial walls. In contrast, HDL are directly involved in the removal of cholesterol from peripheral tissues, carrying it back either to the liver or to other lipoproteins, by a mechanism known as "reverse cholesterol transport" (RCT). The "protective" role of
Patents 185
HDL has been confirmed in a number of studies (e.g. Miller et al. Lancet, 1977:965-968 and Whayne et al. Atherosclerosis 1981;39:411-419). In these, the elevated levels of LDL, less so of VLDL, seem to be clearly associated with an increased cardiovascular risk, whereas high HDL levels seem to confer cardiovascular protection. The protective role of HDL has been further strongly supported by the in vivo studies, showing that HDL infusions into rabbits may hinder the development of cholesterol induced arterial lesions (Badimon et al, Lab. Invest. 60, 455-61, 1989)) and/or induce regression of same (Badimon et al, J Clin Invest. 85, 1234-41, 1990). Web site: http://www.delphion.com/details?pn=US06617134__ •
Endothelial NOS transgenic animals and methods of use Inventor(s): Fishman; Mark C. (Newton Center, MA), Huang; Paul L. (Boston, MA), Moskowitz; Michael A. (Belmont, MA) Assignee(s): The General Hospital Corporation (Boston, MA) Patent Number: 6,630,347 Date filed: October 20, 2000 Abstract: This invention relates to transgenic non-human animals comprising a disrupted endothelial nitric oxide synthase gene. These animals exhibit abnormal wound-healing properties and hypertension. This invention also relates to methods of using the transgenic animals to screen for compounds having a potential therapeutic utility for vascular endothelial disorders, such as hypertension, cerebral ischemia or stroke, atherosclerosis and wound-healing activities. Moreover, this invention also relates to methods of treating a patient suffering from hypertension and wound-healing abnormalities with the compounds identified using the transgenic animals, and methods of making the transgenic animals. A method of treating a wound using nitroglycerin is also provided. Excerpt(s): Part of the work performed during the development of this invention was supported by U.S. Government funds. The U.S. Government may have certain rights in this invention. This invention relates to transgenic non-human animals comprising a disrupted endothelial nitric oxide synthase gene. This invention also relates to methods of using these transgenic animals to screen compounds for activity against vascular endothelial disorders such as hypertension, stroke, and atherosclerosis, as well as for wound healing activity; methods of treating a patient suffering from a vascular endothelial disorder; methods of making the transgenic animals; and cell lines comprising a disrupted eNOS gene. In 1980, Furchgott and Zawadzzi first proposed the existence of endothelium derived relaxing factor or EDRF, later identified as nitric oxide. Furchgott (1980); Furchgott (1988); Ignarro (1988); Palmer (1987). Nitric oxide is an important messenger molecule produced by endothelial cells, neurons, macrophages, and other tissues. Marietta (1989); Moncada (1991); Nathan (1992); Snyder (1992); and Dawson et al. (1992). Since nitric oxide is a gas with no known storage mechanism, it diffuses freely across membranes and is extremely labile. Nitric oxide has a biological half-life on the order of seconds.

Fas ligand-like protein, its production and use Inventor(s): Hikichi; Yukiko (Tsukuba, JP), Nishi; Kazunori (Tsukuba, JP), Shintani; Yasushi (Tsukuba, JP) Assignee(s): Takeda Chemical Industries, Ltd. (Osaka, JP) Patent Number: 6,590,090 Date filed: August 31, 2000 Abstract: This invention relates to a Fas ligand-like protein having an apotosis-inducing actibvity, etc. or its salt, a partial peptide of the protein or its salt; a DNA coding for the protein; a recombinant vector; a transformant; a method for producing the protein, a pharmaceutical composition comprising the protein, the partial peptide or its salt; and an antibody to the protein or the partial peptide. The protein, the partial peptide or its salt, and the DNA are useful as a prophylactic or therapeutic agent for cancer, viral infection, Helicobacter pylori infection, invasive staphylococcia, hepatitis, nephritis, bone disease, atherosclerosis or pain. The antibody can be used in assay of the protein, the partial peptide or its salt. The protein, the partial peptide or its salt is useful as a reagent for the screening for candidate medical compounds. Excerpt(s): The present invention relates to a novel fas ligand-like protein having an apotosis-inducing activity, etc. and a DNA coding for the protein. A multicellular organism maintains its homeostasis ingeniously by controlling the proliferation and death of its cells. In the course of ontogenesis, many cells are eliminated through apotosis, and even in a mature organism the cells constituting its tissues maintain their functional integrity balancing proliferation against death. Cell death in this context is generally termed "programmed cell death", which is known to occur through the process of apotosis which is morphologically distinguished from that of necrosis, the accidental cell death caused by physical and chemical factors. Apoptotic cell death is characterized by blebbing of the cell membrane, chromatin condensation and DNA fragmentation, with the affected cells being eventually removed by phagocytic cells such as macrophages for reutilization (International Review of Cytology, 68, 251-306, 1980). Many physiological and pathological events related to apotosis have been identified until now and many attempts made to diagnose, prevent, or treat various diseases through induction or inhibition of the process of apotosis (Science, 267, 1456-1462, 1995). Apotosis is one of the vital phenomena which are attracting more than usual attention in the pharmaceutical industries. Web site: http://www.delphion.com/details?pn=US06590090__

Functional assay of high-density lipoprotein Inventor(s): Fogelman; Alan M. (Beverly Hills, CA), Hama; Susan (Torrance, CA), Navab; Mohamad (Los Angeles, CA) Assignee(s): The Regents of the University of California (Oakland, CA) Patent Number: 6,596,544 Date filed: March 31, 2000 Abstract: This invention provides novel assays that are prognostic and/or diagnostic for atherosclerosis or risk of atherosclerosis. It was discovered that high density lipoprotein (HDL) or components thereof can prevent the oxidation of lipids (e.g. lipids present in LDLs) and can also repair (reduce) already oxidized lipids and thereby
Patents 187
reduce the inflammatory response associated with and characteristic of atherosclerotic plaque formation. Moreover it was a discovery of this invention that individuals vary in the ability of their HDL to afford such protection. Thus an assay of HDL protective and/or repair activity provides a highly effective assay for risk of atherosclerosis and its associated pathologies and such assays are provided herein. Excerpt(s): This application is related to an application naming Fogelman et al. as inventors entitled "CONTROL OF A GENE INDUCED BY OXIDIZED LIPIDS IN HUMAN ARTERY WALL CELLS", filed on Mar. 31, 2000 which is incorporated herein by reference in its entirety for all purposes. Cardiovascular disease is a leading cause of morbidity and mortality, particularly in the United States and in Western European countries. Several causative factors are implicated in the development of cardiovascular disease including hereditary predisposition to the disease, gender, lifestyle factors such as smoking and diet, age, hypertension, and hyperlipidemia, including hypercholesterolemia. Several of these factors, particularly hyperlipidemia and hypercholesteremia (high blood cholesterol concentrations) provide a significant risk factor associated with atherosclerosis. Cholesterol is present in the blood as free and esterified cholesterol within lipoprotein particles, commonly known as chylomicrons, very low density lipoproteins (VLDLs), low density lipoproteins (LDLs), and high density lipoproteins (HDLs). Concentration of total cholesterol in the blood is influenced by (1) absorption of cholesterol from the digestive tract, (2) synthesis of cholesterol from dietary constituents such as carbohydrates, proteins, fats and ethanol, and (3) removal of cholesterol from blood by tissues, especially the liver, and subsequent conversion of the cholesterol to bile acids, steroid hormones, and biliary cholesterol.

Irreversible inhibitors of tyrosine kinases Inventor(s): Bridges; Alexander James (Saline, MI), Denny; William Alexander (Auckland, NZ), Dobrusin; Ellen Myra (Ann Arbor, MI), Doherty; Annette Marian (Paris, FR), Fry; David William (Ypsilanti, MI), McNamara; Dennis Joseph (Ann Arbor, MI), Showalter; Howard Daniel Hollis (Ann Arbor, MI), Smaill; Jeffrey B. (Auckland, NZ), Zhou; Hairong (Ann Arbor, MI) Assignee(s): Warner-Lambert Company (Morris Plains, NJ) Patent Number: 6,602,863 Date filed: September 27, 2000 Abstract: The present invention provides compounds that are irreversible inhibitors of tyrosine kinases. Also provided is a method of treating cancer, restenosis, atherosclerosis, endometriosis, and psoriasis and a pharmaceutical composition that comprises a compound that is an irreversible inhibitor of tyrosine kinases. Excerpt(s): This invention relates to compounds that are irreversible inhibitors of tyrosine kinases. This invention also relates to a method of treating cancer, atherosclerosis, restenosis, endometriosis, and psoriasis, and to a pharmaceutical composition that comprises a compound that is an irreversible inhibitor of tyrosine kinases. Cancer has been viewed as a disease of the intracellular signalling system, or signal transduction mechanism. Cells receive instructions from many extracellular sources, instructing them to either proliferate or not to proliferate. The purpose of the signal transduction system is to receive these and other signals at the cell surface, get them into the cell, and then pass the signals on to the nucleus, the cytoskeleton, and transport and protein synthesis machinery. The most common cause of cancer is a series of defects, either in these proteins, when they are mutated, or in the regulation of the quantity of the protein in the cell such that it is over or under produced. Most often, there are key lesions in the cell which lead to a constitutive state whereby the cell nucleus receives a signal to proliferate, when this signal is not actually present. This can occur through a variety of mechanisms. Sometimes the cell may start to produce an authentic growth factor for its own receptors when it should not, the so-called autocrine loop mechanism. Mutations to the cell surface receptors, which usually signal into the cell by means of tyrosine kinases, can lead to activation of the kinase in the absence of ligand, and passing of a signal which is not really there. Alternatively, many surface kinases can be overexpressed on the cell surface leading to an inappropriately strong response to a weak signal. There are many levels inside the cell at which mutation or overexpression can lead to the same spurious signal arising in the cell, and there are many other kinds of signalling defects involved in cancer. This invention touches upon cancers which are driven by the three mechanisms just described, and which involve cell surface receptors of the epidermal growth factor receptor tyrosine kinase family (EGFR).
Patents 189
This family consists of the EGF receptor (also known as Erb-B1), the Erb-B2 receptor, and its constitutively active oncoprotein mutant Neu, the Erb-B3 receptor and the ErbB4 receptor. Additionally, other biological processes driven through members of the EGF family of receptors can also be treated by compounds of the invention described below.

Low density lipoprotein binding proteins and their use in diagnosing and treating atherosclerosis Inventor(s): Arjona; Anibal A. (Boston, MA), Law; Simon W. (Lexington, MA), Lees; Ann M. (Brookline, MA), Lees; Robert S. (Brookline, MA) Assignee(s): Boston Heart Foundation, Inc. (Cambridge, MA) Patent Number: 6,605,588 Date filed: March 2, 2000 Abstract: Isolated polynucleotides encoding novel polypeptides which are capable of binding to native and methylated LDL (low density lipoprotein), the isolated polypeptides, called LBPs (LDL binding proteins), and biologically active fragments and analogs thereof, are described. Also described are methods for determining if an animal is at risk for atherosclerosis, methods for evaluating an agent for use in treating atherosclerosis, methods for treating atherosclerosis, and methods for treating a cell having an abnormality in structure or metabolism of LBP. Pharmaceutical compositions and vaccine compositions are also provided. Excerpt(s): Atherosclerosis is the principal cause of heart attacks and strokes. It has been reported that about 50% of all deaths in the United States, Europe and Japan are due to atherosclerosis. Atherosclerotic lesions in the arterial wall characterize atherosclerosis. Cholesteryl esters (CE) are present in these atherosclerotic lesions. Low density lipoprotein (LDL) has been shown to be the major carrier of plasma CE, and has been implicated as the agent by which CE enter the atherosclerotic lesions. Scattered groups of lipid-filled macrophages, called foam cells, are the first visible signs of atherosclerosis and are described as type I lesions. These macrophages are reported to contain CE derived from LDL. The macrophages recognize oxidized LDL, but not native LDL, and become foam cells by phagocytosing oxidized LDL. Larger, more organized collections of foam cells, fatty streaks, represent type II lesions. These lesions further develop into complex lesions called plaques, which can result in impeding the flow of blood in the artery. It is widely believed that accumulation of LDL in the artery depends on the presence of functionally modified endothelial cells in the arterial wall. It has been reported in animal models of atherosclerosis that LDL, both native LDL and methylated LDL, accumulates focally and irreversibly only at the edges of regenerating endothelial islands in aortic lesions, where functionally modified endothelial cells are present, but not in the centers of these islands where endothelial regeneration is completed. Similarly, LDL accumulates in human atherosclerotic lesions. The mechanism by which the LDL accumulates focally and irreversibly in arterial lesions has not heretofore been understood.

Method for preventing, stabilizing or causing regression of atherosclerosis employing a combination of a cholesterol lowering drug and an ace inhibitor Inventor(s): Bergey; James L. (Lansdale, PA), Kawano; James C. (Narberth, PA), Tschollar; Werner (Lawrenceville, NJ), Yonce; Cary S. (Newtown, PA) Assignee(s): E.R. Squibb & Sons, Inc. (Princeton, NJ) Patent Number: 6,630,502 Date filed: December 2, 1991 Abstract: A method is provided for slowing the progression of atherosclerosis in hypertensive or normotensive patients and reducing or eliminating atherosclerotic lesions in such patients by administering a combination of a cholesterol lowering drug such as pravastatin, and an ACE inhibitor, especially one containing a mercapto moiety, such as captopril or zofenopril. Excerpt(s): The present invention relates to a method for preventing, stabilizing or causing regression of atherosclerosis in mammalian species by administering a combination of a cholesterol lowering drug, such as an HMG CoA reductase inhibitor, for example, pravastatin, and an ACE inhibitor, preferably an ACE inhibitor containing a mercapto moiety, such as captopril or zofenopril, and to a pharmaceutical combination for use in such method. The proatherosclerotic effect of elevated serum cholesterol on vascular tissue is well documented (Weinstein and Heider, "Protective action of calcium channel antagonists in atherogenesis and vascular injury," Am. J. Hypertens. 2: 20512,1989). It is also well known that platelets which may participate in the atherogenic process do so via mediators released upon activation (thromboxane A.sub.2 (TXA.sub.2), platelet aggregating factor (PAF), etc.,) which in turn stimulate smooth muscle cells to contract as well as to proliferate. The latter effect is an important step in atherosclerotic plaque formation (Hoak, "Platelets and atherosclerosis," Semin. Thromb. Hemost. 14: 202-5, 1988). Many of the stimulatory effects of prostanoids on vascular smooth muscle can be reversed by endothelium derived relaxing factor (EDRF), a substance whose metabolic stability and/or efficacy appears to be enhanced by captopril (Goldschmidt and Tallarida, "Effect of captopril exposure on endotheliumdependent relaxation in rabbit aorta," F.A.S.E.B.

Method for the prediction of preeclampsia and other diseases Inventor(s): Arbogast; Bradley W. (Johnson City, TN) Assignee(s): Arbogast Pharmaceuticals, Inc. (Johnson City, TN) Patent Number: 6,642,055 Date filed: March 31, 2000 Abstract: The invention disclosed is a process for determining the cytoprotective activity of plasma that prevents the destruction of endothelial cells and forestalls the development of a number of diseases such as atherosclerosis, preeclampsia, edema, nephrotic syndrome, and stroke. The present invention includes a method of diagnosing a patient's proclivity to develop a disease having a correlation to a reduction in the concentration of pI 5.6 albumin in the plasma by determining a value indicative of the concentration of the pI 5.6 albumin that is not bound to VLDL ("free pI 5.6 albumin") in the patient's blood serum. The preferred embodiment of the process utilizes in vitro
Patents 191
methods to obtain an indicator of the free pI 5.6 albumin instead of directly measuring the concentration of the free pI 5.6 albumin. The preferred method comprises the steps of:(a) providing a plasma sample containing free albumin, triglycerides, very low density lipoproteins, low density lipoproteins, and non-esterified fatty acids bound to the free albumin;(b) determining the concentration of the free albumin;(c) determining the concentration of the non-esterified fatty acids bound to the free albumin; and(d) calculating a value indicative of the toxicity preventing ability of the plasma by comparing the concentration of the free albumin to the concentration of the nonesterified fatty acids bound to the free albumin. The present process does not provide direct measurement of the cytoprotective activity of plasma, but rather, an empirical value which has clinical relevance in identifying patients with a high chance of developing diseases inhibited by pI 5.6 albumin. Excerpt(s): The present invention relates to methods for predicting and following illnesses. More particularly, the present invention relates to the diagnosis of preeclampsia and other diseases. Vascular disease is often related to the composition of blood flowing therethrough. In particular, high concentrations of very low density lipoproteins (VLDL) in blood have a deleterious effect on vascular integrity. Very low density lipoproteins in blood tend to break down the inner vascular walls causing vascular diseases including preeclampsia, atherosclerosis, stroke, peripheral vascular disease, diabetic vascular disease, and such. Methods providing earlier detection of vascular diseases, and methods for diagnosing a patient's proclivity toward developing a vascular disease at a later point in his life are desirable so that such disease may be better controlled, or even avoided. The early detection of preeclampsia is particularly important. Web site: http://www.delphion.com/details?pn=US06642055__ •

and amphoterin, for the management, treatment, control, or as an adjunct treatment of diseases caused by RAGE. Incubation of proteins or lipids with aldose sugars results in nonenzymatic glycation and oxidation of amino groups on proteins to form Amadori adducts. Over time, the adducts undergo additional rearrangements, dehydrations, and cross-linking with other proteins to form complexes known as Advanced Glycosylation End Products (AGEs). Factors which promote formation of AGEs included delayed protein turnover (e.g. as in amyloidoses), accumulation of macromolecules having high lysine content, and high blood glucose levels (e.g. as in diabetes) (Hori et al., J. Biol. Chem. 270: 25752-761, (1995)). AGEs have implicated in a variety of disorders including complications associated with diabetes and normal aging. In addition to AGEs, other compounds can bind to, and modulate RAGE. In normal development, RAGE interacts with amphoterin, a polypeptide which mediates neurite outgrowth in cultured embryonic neurons (Hori et al., 1995). RAGE has also been shown to interact with ENRAGE, a protein having substantial similarity to calgranulin (Hofmann et al., Cell 97:889-901 (1999)). RAGE has also been shown to interact with.beta.-amyloid (Yan et al., Nature 389:589-595, (1997); Yan et al., Nature 382:685-691 (1996); Yan et al., Proc. Natl.Acad. Sci., 94:5296-5301 (1997)).

(Cambridge, MA) Patent Number: 6,616,926 Date filed: November 2, 2000 Abstract: Anti-hedgehog antibodies directed at blocking the binding of hedgehog to its receptor patched-1, will impair lipid metabolism and storage. This invention presents methods for the treatment of a variety of lipid metabolism and lipid storage disorders, aberrant apolipoprotein expression, atherosclerosis and other lipid associated disorders using lipid modulators such as hedgehog antagonists or hedgehog agonists. Excerpt(s): This invention relates generally to methods for modulating the metabolism and storage of lipids. The invention relates particularly to the use of lipid metabolism and storage modulators such as agonists or antagonists of hedgehog activity to alter the metabolism of lipids in the gastrointestinal tract, as well as to alter the storage of lipids in gut epithelial tissue. Pathological conditions that affect storage, breakdown and intestinal absorption of lipids are included in a broad category of so-called "lipid metabolism disorders," and there are a variety of disorders that have been diagnosed. These include: diet-induced and regular hypercholesterolemia (Farese et al. Proc. Natl. Acad. Sci. USA 1995 92:1774-1778), abetalipoproteinemia and hypobetalipoproteinemia (Linton et al. J. Lipid Res.1993 34:521-541.) Several other lipid metabolism disorders of unknown origin have also been identified including Anderson's disease (Anderson et al. Med. J. Aust. 1961 11:617-621), and atherosclerosis (Purcell-Huynh et al. J. Clin. Invest. 1995 95:2246-2257.) General symptoms of lipid metabolism disorders include, but are not limited to, chronic diarrhea, inadequate weight gain or weight loss, inability to lose excess weight and general failure to thrive. (Case 35-1999, New England Journal of Medicine; 327: 628-635 1992.) The various lipid metabolism disorders have been thought to originate through aberrant expression of apolipoproteins and/or regulation of genes responsible for various aspects of lipid metabolism. The various lipid metabolism disorders are also thought to originate via malfunctions in embryonic tissue

development. The generation of the intestines from the embryonic gut material depends solely on intercellular signaling between endodermal and mesodermal cells of the gut. It has been widely recognized that the hedgehog-signaling pathway plays a critical role in the direction of specialized mesoderm differentiation in the intestine and pancreas. (Apelqvist et al. Current Biology 1997 7:801-804.) Hedgehog is initially expressed in mouse embryos in the ventral part of the foregut endoderm, and has been shown to mediate endodermally derived signals in embryonic hindgut. (Id.) Specifically, mice with targeted deletion of hedgehog have evident foregut defects that are apparent as early as embryonic day 9.5, when the tracheal diverticulum begins to outgrow, suggesting that hedgehog and its signaling components are involved in foregut defects in humans.

Methods of using pomegranate extracts for causing regression in lesions due to arteriosclerosis in humans Inventor(s): Aviram; Michael (Kiriat-Haim, IL), Dornfeld; Leslie (Los Angeles, CA) Assignee(s): Stewart and Lynda Resnick Revocable Trust (Los Angeles, CA) Patent Number: 6,641,850 Date filed: November 19, 2001 Abstract: Methods of using pomegranate extracts of the present invention for treating patients with atherosclerosis, or increased intima-media thickness of an artery, are provided. The methods comprise the step of administering to the patient a composition comprising a therapeutically effective amount of an extract from pomegranate. The methods of the present invention may also be used to decrease the incidence of stroke or heart attack in a patient. Excerpt(s): The invention relates generally to pomegranate extracts and methods of using thereof, and specifically to methods of using pomegranate extracts for causing regression in lesions due to arteriosclerosis in humans. Throughout this application, various references are referred to within parentheses. Disclosures of these publications in their entireties are hereby incorporated by reference into this application to more fully describe the state of the art to which this invention pertains. Full bibliographic citation for these references may be found at the end of this application, preceding the claims. Oxidative stress, a major contributor to cardiovascular diseases (1), is associated with lipid peroxidation in arterial macrophages and in lipoproteins (1-3). Oxidized lowdensity lipoprotein (Ox-LDL) was shown to be atherogenic (2-4), thus, interventions to inhibit LDL oxidation by dietary antioxidants (4, 5) is of major importance to attenuate atherosclerosis. It was recently shown that vitamin E supplementation to patients with carotid artery stenosis inhibited LDL accumulation in arterial macrophages (6). Protection of lipids from oxidation can be also achieved by serum paraoxonase (PON1, an HDL-associated esterase that can hydrolyze and reduce specific lipid peroxides in arterial cells and lipoproteins in coronary and carotid lesions (7-10).

Molecularly imprinted polymers for the treatment and diagnosis of medical conditions Inventor(s): Green; Bernard S. (Kibbutz Yavne, IL), Priwler; Morris (Modi'in, IL) Assignee(s): Semorex Inc. (North Brunswick, NJ) Patent Number: 6,638,498 Date filed: June 29, 2001 Abstract: Improved molecularly imprinted polymers (MIPs) with both higher and more specific binding capacity for particular bile acids and/or salts, including the synthesis of such MIPs, the compounds themselves, and specific applications thereof. As an example of a particularly preferred specific application of these compounds, the present invention encompasses the use of the MIPs as sequestrants in the gastrointestinal tract, particularly in order to bind and therefore remove toxins from the gastrointestinal tract. In addition, the present invention is also useful for treatment of various diseases which are related to, and/or characterized by, an effect of bile acids and salts, such as atherosclerosis, liver disease and various diseases of the gastrointestinal tract. The MIP compounds of the present invention are also useful for combination therapy with other medications and for diagnosis and monitoring of diseases. Excerpt(s): The present invention is related to novel molecularly imprinted polymers, and in particular to improvements in the production of molecularly imprinted polymers (MIPs), as well as to these specific MIPs, and to the use of MIPs for specific applications. The MIPs of the present invention are particularly suitable for binding to, and thereby removing, toxins in the gastrointestinal tract. As an exemplary implementation, the present invention is described with regard to the removal of bile acids and bile salts from the gastrointestinal tract. In addition, the present invention is also useful for treatment of various diseases which are related to, and/or characterized by an effect of, bile acids and bile salts, such as atherosclerosis, cancer, liver disease and various diseases of the gastrointestinal tract. The MIP compounds of the present invention are also useful for combination therapy with other medications. These medications may involve mechanisms of action that lower or change the composition of bile acids and salts in the body or by a different mechanism. In addition the present invention also is useful for the diagnosis and monitoring of various diseases by selectively binding to an established marker which is then identified using known binding indicator techniques such as fluorescence. As an illustrative example for implementation, the present invention is described with regard to the diagnosis of medical conditions which are related to, and or characterized by an effect of, bile acids and/or bile salts, such as atherosclerosis, various diseases of the gastrointestinal tract, cancer and inflammatory conditions. This is achieved by determining the level of at least one specific bile acid or salt or the ratio of at least one specific bile acid or to at least a second specific bile acid or salt and determining whether these levels fall within an establish range which indicates the potential existence of the relevant disease. The analysis is performed on bile acids and or bile salts found in serum, bile, gastric contents, and feces. The subject of molecularly imprinted polymers has been extensively reviewed (e.g., G. Wulff, Angew. Chem., Int. Ed. Engl. 1995, 34, 1812-1832; A. G. Mayyes and K. Mosbach, Trends Anal. Chem. 1997, 16, 321-332; E. N. Vulfson, C. Alexander, and M. J. Whitcombe Chem. Brit. 1997, 33, 23-26; K. Haupt and K. Mosbach, Trends Biotechnol. 1998, 16, 468-475; Molecular and Ionic Recognition with Imprinted Polymers, ACS Symp. Ser. 703; R. A. Bartsch and M. Maeda, Eds.; American Chemical Society, Washington, D.C., 1998) and a number of patents on this topic have been issued [e.g., U.S. Pat. No. 4,127,730 (Wulff, G., Sarhan A.); U.S. Pat. No. 5,110,833 (Mosbach. K.); U.S. Pat. No. 5,630,978 (Domb, A.,);

U.S. Pat. No. 5,587,273 (Yan, M. et al.); U.S. Pat. No. 5,872,198 (Mosbach, K. et al;)]. A schematic depiction of the formation of MIPs for deoxycholic acid (DCA) and glycodeoxycholic acid (GDCA) is shown in FIGS. 1A and 1B. Although the binding/recognition site is actually a family of non-homogeneous sites, the scheme illustrates how the cavities for two similar substances may differ. The synthesis of MIPs, including those described with regard to the present invention in the "Description of the Preferred Embodiments" below, is performed with functional monomers. The monomers which were used for the present invention include all of the monomers listed in the following section. The synthesis of these monomers and related derivatives and analogs can be performed by organic chemists of ordinary skill in the art. It should be noted that although the present invention is described with regard to MIPs which bind bile acids and bile salts, this is for the purposes of description only and is not intended to be limiting in any way.

PARP inhibitors, pharmaceutical compositions comprising same, and methods of using same Inventor(s): Jackson; Paul F. (Bel Air, MD), Li; Jia-He (Cockeysville, MD), Maclin; Keith M. (Baltimore, MD), Zhang; Jie (Ellicott City, MD) Assignee(s): Guilford Pharmaceuticals Inc. (Baltimore, MD) Patent Number: 6,635,642 Date filed: September 1, 1998 Abstract: The present invention relates to PARP inhibitors, pharmaceutical compositions comprising the same, and methods of using the same to treat tissue damage resulting from cell damage or death due to necrosis or apoptosis, effect neuronal activities not mediated by NMDA toxicity; to treat neural tissue damage resulting from ischemia and reperfusion injury, neurological disorders and neurodegenerative diseases; to prevent or treat vascular stroke; to treat or prevent cardiovascular disorders; to treat other conditions and/or disorders such as age-related macular degeneration, AIDS and other immune senescence diseases, arthritis, atherosclerosis, cachexia, cancer, degenerative diseases of skeletal muscle involving replicative senescence, diabetes, head trauma, immune senescence, inflammatory bowel disorders (such as colitis and Crohn's disease), muscular dystrophy, osteoarthritis, osteoporosis, chronic and/or acute pain (such as neuropathic pain), renal failure, retinal ischemia, septic shock (such as endotoxic shock), organ damage due to transplantation, and skin aging; to extend the lifespan and proliferative capacity of cells; to alter gene expression of senescent cells; or to radiosensitize hypoxic tumor cells. Excerpt(s): The present invention relates to inhibitors of the nucleic enzyme poly(adenosine 5'-diphospho-ribose) polymerase ["poly(ADP-ribose) polymerase" or "PARP", which is also sometimes called "PARS" for poly(ADP-ribose) synthetase]. More particularly, the invention relates to the use of PARP inhibitors to prevent and/or treat tissue damage resulting from cell damage or death due to necrosis or apoptosis; neural tissue damage resulting from ischemia and reperfusion injury; neurological disorders and neurodegenerative diseases; to prevent or treat vascular stroke; to treat or prevent cardiovascular disorders; to treat other conditions and/or disorders such as age-related macular degeneration, AIDS and other immune senescence diseases, arthritis, atherosclerosis, cachexia, cancer, degenerative diseases of skeletal muscle involving replicative senescence, diabetes, head trauma, immune senescence, inflammatory bowel

disorders (such as colitis and Crohn's disease), muscular dystrophy, osteoarthritis, osteoporosis, chronic and acute pain (such as neuropathic pain), renal failure, retinal ischemia, septic shock (such as endotoxic shock), and skin aging; to extend the lifespan and proliferative capacity of cells; to alter gene expression of senescent cells; or to radiosensitize hypoxic tumor cells. Poly(ADP-ribose) polymerase ("PARP") is an enzyme located in the nuclei of cells of various organs, including muscle, heart and brain cells. PARP plays a physiological role in the repair of strand breaks in DNA. Once activated by damaged DNA fragments, PARP catalyzes the attachment of up to 100 ADP-ribose units to a variety of nuclear proteins, including histones and PARP itself. While the exact range of functions of PARP has not been fully established, this enzyme is thought to play a role in enhancing DNA repair. During major cellular stresses, however, the extensive activation of PARP can rapidly lead to cell damage or death through depletion of energy stores. Four molecules of ATP are consumed for every molecule of NAD (the source of ADP-ribose) regenerated. Thus, NAD, the substrate of PARP, is depleted by massive PARP activation and, in the efforts to re-synthesize NAD, ATP may also be depleted.

Tyrosine kinase inhibitors Inventor(s): Bilodeau; Mark T. (Lansdale, PA), Hartman; George D. (Lansdale, PA), Hungate; Randall W. (Newbury Park, CA), Manley; Peter J. (Harleysville, PA), Rodman; Leonard (New York, NY) Assignee(s): Merck & Co., Inc. (Rahway, NJ) Patent Number: 6,586,423 Date filed: February 1, 2002 Excerpt(s): The present invention relates to compounds which inhibit, regulate and/or modulate tyrosine kinase signal transduction, compositions which contain these compounds, and methods of using them to treat tyrosine kinase-dependent diseases and conditions, such as angiogenesis, cancer, tumor growth, atherosclerosis, age related macular degeneration, diabetic retinopathy, inflammatory diseases, and the like in mammals. Tyrosine kinases are a class of enzymes that catalyze the transfer of the terminal phosphate of adenosine triphosphate to tyrosine residues in protein substrates. Tyrosine kinases are believed, by way of substrate phosphorylation, to play critical roles in signal transduction for a number of cell functions. Though the exact mechanisms of signal transduction is still unclear, tyrosine kinases have been shown to be important contributing factors in cell proliferation, carcinogenesis and cell differentiation. Tyrosine kinases can be categorized as receptor type or non-receptor type. Receptor type tyrosine kinases have an extracellular, a transmembrane, and an intracellular portion, while nonreceptor type tyrosine kinases are wholly intracellular.

Use of lecithin-cholesterol acyltransferase (LCAT) to reduce accumulation of cholesterol Inventor(s): Brewer, Jr.; H. Bryan (Rockville, MD), Hoeg; Jeffrey M. (Potomac, MD), Santamarina-Fojo; Silvia (Potomac, MD) Assignee(s): The United States of America as represented by the Department of Health and (Washington, DC) Patent Number: 6,635,614 Date filed: November 22, 1999 Abstract: This invention provides methods for treating atherosclerosis in a mammalian subject by increasing the activity of LCAT in the serum of the subject to a level effective to decrease the accumulation of cholesterol in the subject. Pharmaceutical dosage forms containing LCAT also are provided. Excerpt(s): This invention relates to methods for the prophylactic and therapeutic treatment of atherosclerosis and to diseases relating to a deficiency in lecithincholesterol acyltransferase activity. Atherosclerosis is a pathological condition of mammals characterized by the accumulation of cholesterol in the arteries. Cholesterol accumulates in the foam cells of the arterial wall, thereby narrowing the lumen. This results in decreased flow of blood. The clinical sequelae of atherosclerosis include heart disease and heart attack, stroke, and peripheral vascular disease. Together, these diseases account for more disease-related deaths in industrialized countries than any other cause. The development of human atherosclerosis is inversely related to the concentration of high density lipoproteins (HDL) in the serum. D. J. Gordon and B. M. Rifkind (1989) N. Engi. J. Med. 321:1311. High concentrations of HDL appear to protect against the development of premature atherosclerosis, while low HDL cholesterol concentrations are associated with an increased risk of cardiovascular disease. D. J. Gordon et al. (1986) Circulation 74:1217. It has been proposed that a 1% increase in the concentration of HDL would lead to a 3% reduction in risk for developing clinical atherosclerosis in man. Gordon and Rifkind, supra.

Use of saw palmetto to prevent atherosclerosis Inventor(s): Goldberg; Michael E. (20 Aspen Dr., Ivyland, PA 18974), Weisman; Kenneth (30 Springton Pointe Dr., Newtown Square, PA 19073) Assignee(s): none reported Patent Number: 6,627,227 Date filed: May 8, 2001 Abstract: A method of decreasing atherosclerosis and its complications including but not limited to myocardial infarction, stroke, and peripheral vascular disease comprising administering to a human or animal an amount of saw palmetto or Permixon containing saw palmetto sufficient to decrease atherosclerosis and its complications. Excerpt(s): There are many steps in the biosynthesis and utilization by the tissues of testosterone. Testosterone is made mostly in the testicles. A lesser amount is made in the adrenals. Production is stimulated by secretion of GnRH or LHRH by the brain, which causes secretion of luteinizing hormone (LH) by the pituitary, which causes the testicles to make testosterone. Testosterone then flows into the blood stream and is absorbed by
198 Atherosclerosis
the target cells. Here it binds to a receptor and is transported into the cell and converted to dihydrotestosterone. This is bound and carried to the nucleus of the cell where it redirects cellular activity by turning on and off DNA. Hormonal manipulation is a term which refers to the reduction of testosterone or its effects by blocking any step in the above process in order to gain a desired effect. Until now the uses of hormonal manipulation include for example treating prostatic carcinoma, and treatment for baldness. For instance, leuprolide acetate is one of the compounds we previously discovered being effective in the prevention of such cardiac events. Leuprolide acetate is a synthetic nonapeptide of naturally occurring gonadotropin-releasing hormone (GnRH or LH-RH), the chemical name is 5-oxo-L-prolyl-L-histidyl-L-tryptophyl-L-seryl-Ltyrosyl-D-leucyl-L-leucyl -L-arginyl-N-ethyl-L-prolinamide acetate salt sold under the trade name Lupron or Lupron Depot, as identified by U.S. Pat. No. 4,897,256, the entire disclosure in incorporated by reference herein, is known for use in the treatment of prostatic carcinoma. Leuprolide is known to decrease levels of LHRH, LH and Testosterone (a sex hormone). Another compound we previously discovered as being effective in the prevention of such cardiac events is Goserelin acetate. Goserelin Acetate is a synthetic decapeptide analogue of LHRH or GnRH, is chemically described as an acetate salt of [D-Ser(Bu.sup.t).sup.6 Azygly.sup.10] LHRH. Its chemical structure is pyro-Glu-His-Trp-Ser-Tyr-D-Ser(Bu.sup.t)-Leu-Arg-Pro-Azgly-NH2 acetate [C59H84N18014 (C2H4O2) sold under the trademark Zoladex, as identified by the U.S. Pat.

These compounds are potent inhibitors of kinases such as cyclin-dependent (cdks) and growth factor-mediated kinases.The present invention also provides a method of treating cell proliferative disorders 1 Excerpt(s): This invention relates to 2-Thia-1,6,8-Triaza-Naphthalene-2,2-Dioxi- des as inhibitors of kinases, particularly cyclin-dependent kinases. The compounds of the invention are useful for the treatment of inflammation, cell proliferative diseases such as cancer and restenosis, and neurodegenerative diseases such as Alzheimer's disease. Cyclin-dependent kinases and related serine/threonine protein kinases are important cellular enzymes that perform essential functions in regulating cell division and proliferation. The cyclin-dependent kinase catalytic units, of which nine have now been described, are activated by regulatory subunits known as cyclins. At least 16 mammalian cyclins have been identified (Johnson, D. G. & Walker, C. L. Annu. Rev. Pharmacol. Toxicol 1999, 39, 295-312). Cyclin D/Cdk4, Cyclin D/Cdk6, CyclinB/Cdk1, Cyclin A/cdk2 and Cyclin E/cdk2 are all important regulators of cell cycle progression. Other functions of cyclin/Cdk heterodimers include regulation of transcription, DNA repair, differentiation and apoptosis. Increased activity or temporally abnormal activation of certain of these kinases has been shown to result in the development of human tumors and other proliferative disorders such as restenosis. Indeed, human tumor development is commonly associated with alterations in either the Cdk proteins

themselves or their regulators (Cordon-Cardo, C. Am. J. Pathol. 1995, 147, 545-560; Karp, J. E. & Broder, S. Nat. Med. 1995, 1, 309-320; Hall, M. et al. Adv. Cancer Res. 1996, 68, 67108; Sher, C. J. Science, 1996, 274, 1672-1677). This observation has prompted an intensive search for small molecule CDK inhibitors. Inhibitors of Cdk enzymes may be expected to inhibit uncontrolled cell proliferation (D. W. Fry & M. D. Garrett, Curr. Opin. Endocrine, Metabolic Invet. Drugs, 2000, 2, 40-59.). Indeed, naturally occurring protein inhibitors of Cdks appear to perform this function providing strong validation for this approach. Introduction of p16 into lung cancer cell lines blocked entry into S phase and caused growth inhibition (Jin, X. et al. Cancer Res. 1995, 55, 3250-3253; Chintaia, S. K. et al. Oncogene 1997, 15, 2049-2057). Other studies have demonstrated a similar effect for p27 Craig, C. et al. Oneogene 1997, 14, 2283-2289). Growth inhibition also results from expression of antisense cyclin D1 or Dominant negative (DN) cdk2. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

Metabolic syndrome (a.k.a. insulin resistance syndrome, syndrome X) is a common clinical disorder that is defined as the presence of increased insulin concentrations in association with other disorders including visceral obesity, hyperlipidemia and dyslipidemia, hyperglycemia, hypertension, and sometimes hyperuricemia and renal dysfunction. Metabolic syndrome is considered by many as a common basic defect for type-2 diabetes, android obesity, dyslipidemia, and hypertension, leading to a clustering of these diseases. This syndrome has particular significance since it has been shown to be an antecedent of both type-2 diabetes and atherosclerosis, with cardiovascular events accounting for the majority of deaths in both populations.

Antisense oligonucleotide directed toward mammalian vegf receptor genes and uses thereof Inventor(s): Sirois, Martin G.; (Quebec, CA) Correspondence: Marshall Gerstein & Borun; Sears Tower Suite 6300; 233 South Wacker Drive; Chicago; IL; 60606-6357; US Patent Application Number: 20030186920 Date filed: April 10, 2003 Abstract: The present invention provides antisense oligonucleotides that target the genes and mRNAs encoding mammalian VEGF receptors. Also provided are methods for designing and testing the antisense oligonucleotides. Such oligonucleotides can be used to reduce VEGF-induced inflammation and angiogenesis, for example, pathological angiogenesis, in mammals. Thus, the present invention also pertains to pharmaceutical compositions and formulations used in the treatment of mammals having a disease or disorder characterised by inflammation and/or pathological angiogenesis; including tumour growth and metastasis, ocular diseases (diabetic and perinatal hyperoxic retinopathies, age-related macular degeneration), arthritis, psoriasis and atherosclerosis. Excerpt(s): This application is a continuation in part of U.S. application Ser. No. 09/687,239, filed Oct. 13, 2000, which is hereby incorporated in its entirety. The present invention pertains to the field of antisense oligonucleotides for mammalian VEGF receptor genes and their use as anti-angiogenics and/or anti-inflammatory agents. Angiogenesis is a process by which new capillary vessels sprout from pre-existing ones, and can be summarised as the culmination of i) increased endothelial cell permeability to plasma proteins; ii) transmigration of inflammatory cells into extracellular matrix; iii) synthesis and release of degrading matrix molecules; iv) release of growth factors; v) migration and proliferation of endothelial cells to distant sites; and vi) capillary tube formation and vascular wall remodelling. Physiological angiogenesis is a highly coordinated process that exclusively occurs in healthy individuals under specific conditions, such as during wound healing, ovulation and pregnancy. At other times, the vasculature is extremely stable, with very low rates of new blood vessels (Fan et al., (1995) Trends Phaimacol. Sci. 16:57-66).

Bicyclic pyrrolyl amides as glycogen phosphorylase inhibitors Inventor(s): Du Bois, Daisy Joe; (Palo Alto, CA) Correspondence: PFIZER INC.; PATENT DEPARTMENT, MS8260-1611; EASTERN POINT ROAD; GROTON; CT; 06340; US Patent Application Number: 20030195361 Date filed: February 14, 2003 Abstract: This invention relates to compounds of Formula I 1or stereoisomers, pharmaceutically acceptable salts or prod rugs thereof or a pharmaceutically acceptable salts of the prodrugs. This invention also relates to pharmaceutical compositions comprising a compound of Formula I, and to methods of treatment of diabetes, insulin resistance, diabetic neuropathy, diabetic nephropathy, diabetic retinopathy, cataracts, hyperglycemia, hypercholesterolemia, hypertension, hyperinsulinemia, hyperlipidemia, atherosclerosis, or tissue ischemia. Excerpt(s): This invention relates to bicyclic pyrrolyl amides and pharmaceutical compositions comprising bicyclic pyrrolyl amides. This invention also relates to the treatment of diabetes, insulin resistance, diabetic neuropathy, diabetic nephropathy, diabetic retinopathy, cataracts, hyperglycemia, hypercholesterolemia, hypertension, hyperinsulinemia, hyperlipidemia, atherosclerosis, and tissue ischemia, particularly myocardial ischemia, using the bicyclic pyrrolyl amides. In spite of the early discovery of insulin and its subsequent widespread use in the treatment of diabetes, and the later discovery of and use of sulfonylureas, biguanides and thiazolidenediones, such as troglitazone, rosiglitazone or pioglitazone, as oral hypoglycemic agents, the treatment of diabetes remains less than satisfactory. The use of insulin requires multiple daily doses, usually by self injection. Determination of the proper dosage of insulin requires frequent estimations of the sugar in urine or blood. The administration of an excess dose of insulin causes hypoglycemia, with effects ranging from mild abnormalities in blood glucose to coma, or even death. Treatment of non-insulin dependent diabetes mellitus (Type II diabetes, NIDDM) usually consists of a combination of diet, exercise, oral hypoglycemic agents, e.g., thiazolidenediones, and in more severe cases, insulin. However, the clinically available hypoglycemic agents can have side effects that limit their use, or an agent may not be effective with a particular patient. In the case of insulin dependent diabetes mellitus (Type I), insulin is usually the primary course of therapy. Hypoglycemic agents that have fewer side effects or succeed where others fail are needed. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Combinations of ileal bile acid transport inhibitors and cholesteryl ester transfer protein inhibitors for cardiovascular indications Inventor(s): Connolly, Daniel T.; (Ballwin, MO), Glenn, Kevin C.; (Maryland Heights, MO), Keller, Bradley T.; (Chesterfield, MO), Schuh, Joseph R.; (St. Louis, MO), Sikorski, James A.; (Des Peres, MO), Smith, Mark E.; (Webster Groves, MO) Correspondence: BANNER & WITCOFF; 1001 G STREET N W; SUITE 1100; WASHINGTON; DC; 20001; US Patent Application Number: 20030203892 Date filed: July 23, 2002 Abstract: The present invention provides combinations of cardiovascular therapeutic compounds for the prophylaxis or treatment of cardiovascular disease including hypercholesterolemia, atherosclerosis, or hyperlipidemia. Combinations disclosed include an ileal bile acid transport inhibitor combined with a cholesteryl ester transfer protein (CETP) inhibitor. Excerpt(s): This application claims priority of U.S. provisional application Ser. No. 60/143,047 filed Jul. 7, 1999 and of U.S. provisional application Ser. No. 60/113,955 filed Dec. 23, 1998. The present invention relates to methods of treating cardiovascular diseases, and specifically relates to combinations of compounds, compositions, and methods for their use in medicine, particularly in the prophylaxis and treatment of hyperlipidemic conditions such as are associated with atherosclerosis, hypercholesterolemia, and other coronary artery disease in mammals. More particularly, the invention relates to ileal bile acid transporter (IBAT) inhibiting compounds. The invention also relates to cholesteryl ester transfer protein (CETP) activity inhibiting compounds. It is well-settled that hyperlipidemic conditions associated with elevated concentrations of total cholesterol and low-density lipoprotein (LDL) cholesterol are major risk factors for coronary heart disease and particularly atherosclerosis. Since high levels of LDL cholesterol increase the risk of atherosclerosis, methods for lowering plasma LDL cholesterol would be therapeutically beneficial for the treatment of atherosclerosis and other diseases associated with accumulation of lipid in the blood vessels. These diseases include, but are not limited to, coronary heart disease, peripheral vascular disease, and stroke. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

208 Atherosclerosis
Abstract: Compositions and methods are disclosed for stimulating or inhibiting angiogenesis and/or cardiovascularization in mammals, including humans. Pharmaceutical compositions are based on polypeptides or antagonists thereto that have been identified for one or more of these uses. Disorders that can be diagnosed, prevented, or treated by the compositions herein include trauma such as wounds, various cancers, and disorders of the vessels including atherosclerosis and cardiac hypertrophy.In addition, the present invention is directed to novel polypeptides and to nucleic acid molecules encoding those polypeptides. Also provided herein are vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising the polypeptides of the present invention fused to heterologous polypeptide sequences, antibodies which bind to the polypeptides of the present invention and to methods for producing the polypeptides of the present invention. Excerpt(s): The present invention relates to compositions and methods useful for the modulation (e.g., promotion or inhibition) of angiogenesis and/or cardiovascularization in mammals in need of such biological effect. The present invention further relates to the diagnosis and treatment of disorders involving angiogenesis (e.g., cardiovascular as well as oncological disorders). Angiogenesis, defined as the growth or sprouting of new blood vessels from existing vessels, is a complex process that primarily occurs during embryonic development. Under normal physiological conditions in adults, angiogenesis takes place only in very restricted situations such as hair growth and wounding healing (Auerbach, W. and Auerbach, R., 1994, Pharmacol Ther 63(3):265-311; Ribatti et al., 1991, Haematologica 76(4):311-20; Risau, 1997, Nature 386(6626):671-4). Unregulated angiogenesis has gradually been recognized to be responsible for a wide range of disorders, including, but not limited to cardiovascular disease, cancer, rheumatoid arthritis, psoriasis and diabetic retinopathy (Folkman, 1995, Nat Med 1(1):27-31; Isner, 1999, Circulation 99(13): 1653-5; Koch, 1998, Arthritis Rheum 41(6):951-62; Walsh, 1999, Rheumatology (Oxford) 38(2): 103-12; Ware and Simons, 1997, Nat Med 3(2): 158-64). Heart failure affects approximately five million Americans, and new cases of heart failure number about 400,000 each year. It is the single most frequent cause of hospitalization for people age 65 and older in the United States. Recent advances in the management of acute cardiac diseases, including acute myocardial infarction, are resulting in an expanding patient population that will eventually develop chronic heart failure. From 1979 to 1995, hospitalizations for congestive heart failure (CHF) rose from 377,000 to 872,000 (a 130 percent increase) and CHF deaths increased 116 percent.

Further, the present invention identifies and describes genes via the ability of their gene products to interact with gene products involved in cardiovascular disease. Still further, the present invention provides methods for the identification and therapeutic use of compounds as treatments of cardiovascular disease. Moreover, the present invention provides methods for the diagnostic monitoring of patients undergoing clinical evaluation for the treatment of cardiovascular disease, and for monitoring the efficacy of compounds in clinical trials. Additionally, the present invention describes methods for the diagnostic evaluation and prognosis of various cardiovascular diseases, and for the identification of subjects exhibiting a predisposition to such conditions. Excerpt(s): This application is a continuation-in-part of co-pending application Ser. No. 08/485,573, filed Jun. 7, 1995, which is a continuation-in-part of co-pending application Ser. No. 08/386,844, filed Feb. 10, 1995, each of which is hereby incorporated by reference in its entirety. The present invention relates to methods and compositions for the treatment and diagnosis of cardiovascular disease, including, but not limited to, atherosclerosis, ischemia/reperfusion, hypertension, restenosis, and arterial inflammation. Genes which are differentially expressed in cardiovascular disease states, relative to their expression in normal, or non-cardiovascular disease states are identified. Genes are also identified via the ability of their gene products to interact with other gene products involved in cardiovascular disease. The genes identified may be used diagnostically or as targets for therapeutic intervention. In this regard, the present invention provides methods for the identification and therapeutic use of compounds in the treatment and diagnosis of cardiovascular disease. Additionally, methods are provided for the diagnostic monitoring of patients undergoing clinical evaluation for the treatment of cardiovascular disease, for monitoring the efficacy of compounds in clinical trials, and for identifying subjects who may be predisposed to cardiovascular disease. Cardiovascular disease is a major health risk throughout the industrialized world. Atherosclerosis, the most prevalent of cardiovascular diseases, is the principal cause of heart attack, stroke, and gangrene of the extremities, and thereby the principle cause of death in the United States. Atherosclerosis is a complex disease involving many cell types and molecular factors (for a detailed review, see Ross, 1993, Nature 362: 801-809). The process, in normal circumstances a protective response to insults to the endothelium and smooth muscle cells (SMCs) of the wall of the artery, consists of the formation of fibrofatty and fibrous lesions or plaques, preceded and accompanied by inflammation. The advanced lesions of atherosclerosis may occlude the artery concerned, and result from an excessive inflammatory-fibroproliferative response to numerous different forms of insult. For example, shear stresses are thought to be responsible for the frequent occurrence of atherosclerotic plaques in regions of the circulatory system where turbulent blood flow occurs, such as branch points and irregular structures.

210 Atherosclerosis
Abstract: The present invention relates compositions and methods for the prophylactic or therapeutic treatment of cardiovascular diseases, particularly restenosis and atherosclerosis. These compositions comprise an effective promotor of reendothelialization, preferably probucol or an analogue thereof, and an inhibitor of lipoprotein oxidation, preferably a probucol-derived bisphenol. Alternatively, the said compositions may comprise a compound that possesses both re-endothelializationpromoting and lipoprotein oxidation-inhibitory effects. This invention further relates to compositions and methods for promoting re-endothelialization. Excerpt(s): The present invention relates to a method of prophylactic or therapeutic treatment of cardiovascular diseases, particularly restenosis and atherosclerosis by a process which both induces re-endothelialization and inhibits the oxidation of lipoproteins. The invention further provides a method of promoting reendothelialization preferably in a vessel wall. Heart disease can result from many factors relating to poor functioning of heart tissue which may manifest in commonly known conditions such as angina, stroke or heart attack. The underlying mechanisms of heart disease are not completely understood. However, it is known that lipid such as cholesterol are actively involved. These can all contribute to atherosclerosis, i.e., the clogging of arteries, and gradually building deposits that eventually cause heart disease. Atherosclerosis causes heart attacks, strokes and leads to the death of almost 50% of Australians. The disease involves intimal thickening and the deposition of lipid (primarily derived from low-density lipoprotein, LDL) in the sub-endothelial space. As lesions develop, the elastic lamina separates the intima from the media, allowing proliferating smooth muscle cells to infiltrate the intima and to deposit increased amounts of extra-cellular matrix. A necrotic core (composed of dead cells, lipid deposits and cholesterol crystals) may develop and the disease can also involve the medial layer. Atherosclerosis can develop silently for many years without symptoms. Often serious events are precipitated when a blood clot lodges in the vessel at a site that is already partially blocked as a result of atherosclerosis.

further relates to compositions for preventing or treating hyperlipemia and foods for preventing or ameliorating hyperlipemia. It still further relates to compositions for preventing or treating obesity and foods for preventing or ameliorating obesity. In recent years, lipid intake has been increasing in Japan with the tendency toward improved and Western-style eating habits, which brings about a problem of excessive fat intake. The excessive fat intake causes obesity and an increase in the serum lipid level and consequently heightens the risk of the onset of various complications thereof (for example, circulatory diseases, in particular, coronary and cerebral vascular accidents and life-style related diseases such as certain cancers including breast cancer and colon cancer). Thus, it becomes a serious social problem from the viewpoint of maintaining and improving national health. It has been pointed out that an increase in the levels of cholesterol in the blood is one of the risk factors of the onset of circulatory diseases. Recently, high concentrations of triacylglycerol (triglyceride) in the blood have also attracted attention as another risk factor independent from those of cholesterol.

Direct arterial infiltration for production of vascular pathology Inventor(s): Edelman, Elazer; (Brookline, MA), Rogers, Campbell; (Westwood, MA), Welt, Frederick G.; (Newton, MA) Correspondence: Attn: Matthew E. Connors; Samuels, Gauthier & Stevens, LLP; Suite 3300; 225 Franklin Street; Boston; MA; 02110; US Patent Application Number: 20030192555 Date filed: May 5, 2003 Abstract: A method of producing a vascular lesion in an animal that resembles atherosclerosic lesions in humans. The method includes introducing cholesterol enriched with LDL or cholesterol enriched with LDL and monocytes, macrophages, leukocytes, smooth muscle cells or platelets into a proliferative lesion created by standard methods, to promote atherosclerosis. Excerpt(s): The invention relates to the field of the local infiltration of cells, cell products or chemical and pharmacological compounds from the lumen of a tubular structure into or around the wall of that structure. In particular this invention is for the infusion of cells, cell products or chemical and pharmacological compounds, alone or in some form of a polymeric material, from an endovascular catheter into or around the wall of a blood vessel. The infusion can be utilized to produce an animal model of atherosclerosis, and in particular to create a vascular lesion in an animal model that more closely resembles the lesions of atherosclerosis seen in humans as well as to the possibility of introducing cellular constituents, cell products or pharmacological agents in order to ameliorate the atherosclerotic or restenotic process. The infusion can also be used to treat the blood vessel wall through the infusion of cells that elaborate therapeutic compounds. Animal models have been invaluable in understanding the basic processes of vascular biology in atherosclerotic and restenotic lesions. However, countless examples of therapies that are advantageous in animal models prove unsuccessful in humans. This has led to skepticism as to the degree to which current experimental models predict human responses. The differences are usually attributed to the inter-species differences in biologic responses. Atherogenesis is the formation of lipid deposits in the intima of arteries that can cause the arterial surface to bulge out into the arterial lumen. In humans, atherogenesis is the result of many different factors acting over a prolonged period of time. Initial lesions called fatty streaks may develop
212 Atherosclerosis
early in life and are manifest by the presence of lipids and macrophages in the innermost layer of the vessel wall. There are many atherogenic determinants including prolonged exposure to factors such as hyperlipidemia, diabetes, cigarette smoking, and hypertension, which lead to further inflammation, endothelial activation, smooth muscle cell proliferation, matrix synthesis, monocyte recruitment, and eventually necrosis, lipid accumulation, and often, calcification. The mature atherosclerotic plaque contains two main components; the first is a soft, lipid-rich core with necrotic debris. The second is a fibrous cap separating the core from the lumen and consisting of smooth muscle cells and collagen. It remains unclear whether this lipid core develops by direct infiltration and deposition of extracellular lipid with subsequent recruitment of macrophages, or whether macrophages endocytose lipid and subsequently necrose leaving lipid and necrotic debris behind. The oxidative state of the lipid core is crucial in determining it's toxic potential. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

The amino acid sequence of PMN-CAP37 revealed its relation to members of the serine protease family that have a conserved catalytic active site consisting of his-57, asp-102 and ser-195 in the charge relay system (2). Of these sites, the conserved histidine and serine of the catalytic triad have been replaced with serine and glycine residues, respectively, rendering CAP37 ineffective as a serine protease (2,3). However, CAP37 has been demonstrated to have a diverse and exciting repertoire of functions. It was first analyzed regarding its bactericidal properties against Gram negative bacteria including, but not limited to, Salmonella typhimurium, Escherichia coli and Pseudomonas aeruginosa (4) and its ability to bind to and neutralize lipopolysaccharide (LPS)(5). Subsequently we showed
Patents 213
CAP37 to be a potent chemoattractant for monocytes (6). Additionally, regarding its effects on the monocyte, CAP37 has been reported to stimulate their survival and thrombospondin secretion (7), also to enhance the LPS-stimulated release of prostaglandin E2 (8), interleukin 6 (IL-6)(9) and tumor necrosis factor-alpha (TNF.alpha.)(8-10). To add even further to its extensive range of known functions, CAP37 has been demonstrated to stimulate the reversible contraction of fibroblasts and endothelial cells (7) and to activate endothelial cell protein kinase C (PKC)(11). Recently, CAP37 released from stimulated PMN was reported to be taken up and sequestered in nearby endothelial mitochondria and has been suggested to protect against apoptosis (12).

Fomulation Inventor(s): Wikstrand, John; (Gothenburg, SE), Berglund, Goran; (Malmo, SE) Correspondence: David P Halstead; Ropes & Gray; One International Place; Boston; MA; 02110-2624; US Patent Application Number: 20030191177 Date filed: December 13, 2002 Abstract: The present invention relates to pharmaceutical formulations comprising a betablocker, in a maintenance dose lower than 50 mg, particularly in the range of 25 to 47 mg, optionally containing a cholesterol lowering agent, in admixture with a pharmaceutically acceptable adjuvant, diluent or carrier, as well as a method of treatment and use of the formulations for the treatment of atherosclerosis and related diseases. Excerpt(s): The present invention relates to pharmaceutical formulations comprising a betablocker, in a maintenance dose lower than 50 mg, in admixture with a pharmaceutically acceptable adjuvant, diluent or carrier, as well as a method of treatment and use of the formulations for the treatment of atherosclerosis and related conditions. There is a constant need for new medications to further reduce the risk of atherosclerotic disease, since this is one of the industrial world's most common health problems. The administration of combinations of.beta.sub.1 selective blockers and lipidlowering drugs to healthy volunteers in order to observe the effects on fat metabolism, ammonia levels and the perception of effort during exercise, was disclosed in Br. J. Clin Pharmacol 1997 vol 43, no 3 pages 291-300. The combinations studied were 1) metoprolol (controlled release) and fluvastatin 2) metoprolol (controlled release) and bezafibrate 3) atenolol (normal release) and fluvastatin and 4) atenolol (normal release) and bezafibrate. The paper concluded that that these four combinations each caused significant reductions in fat metabolism increased plasma ammonia concentrations and raised the perception of exercise. Combination 1) had the least adverse effect but the formulation difference was thought to be a significant factor in explaining the differences observed with respect to combination 3).

Gene therapy approaches to supply apolipoprotein A-I agonists and their use to treat dyslipidemic disorders Inventor(s): Buttner, Klaus; (Epfenbach, DE), Cornut, Isabelle; (Edingen-Neckarhausen, DE), Dasseux, Jean-Louis; (Mannheim, DE), Dufourcq, Jean; (Pessac, FR), Metz, Gunther; (Edingen-Neckarhausen, DE), Sekul, Renate; (Ladenburg, DE) Correspondence: PENNIE AND EDMONDS; 1155 AVENUE OF THE AMERICAS; NEW YORK; NY; 100362711 Patent Application Number: 20030208059 Date filed: October 29, 2002 Abstract: The invention relates to genetic approaches to supply nucleotide sequences encoding modified forms of the native forms of apolipoprotein A-I (ApoA-I): mature ApoA-I, preproApoA-I and proApoA-I; including native ApoA-I modified to contain ApoA-I agonists, peptides which mimic the activity of ApoA-I; ApoA-I superagonists, peptides which exceed the activity of native ApoA-I; and modified native ApoA-I having one or more amphipathic helices replaced by the nucleotide sequences of one or more ApoA-I agonists; for the treatment of disorders associated with dyslipoproteinemia, including cardiovascular disease, atherosclerosis, restenosis, hyperlipidemia, and other disorders such as septic shock. Excerpt(s): The invention relates to gene therapy approaches to supply nucleotide sequences encoding modified forms of the native forms of apolipoprotein A-I (ApoA-I) i.e., mature ApoA-I, preproApoA-I and proApoA-I; ApoA-I peptides; ApoA-I agonists and superagonists, peptides which mimic or exceed the activity of native ApoA-I; and the native ApoA-I gene for the treatment of disorders associated with dyslipoproteinemia, including cardiovascular disease, atherosclerosis, restenosis, hyperlipidemia, and other disorders such as septic shock. Circulating cholesterol is carried by plasma lipoproteins--particles of complex lipid and protein composition that transport lipids in the blood. Low density lipoproteins (LDL), and high density lipoproteins (HDL) are the major cholesterol carriers. LDL are believed to be responsible for the delivery of cholesterol from the liver (where it is synthesized or obtained from dietary sources) to extrahepatic tissues in the body. The term "reverse cholesterol transport" describes the transport of cholesterol from extrahepatic tissues to the liver where it is catabolized and eliminated. It is believed that plasma HDL particles play a major role in the reverse transport process, acting as scavengers of tissue cholesterol. The evidence linking elevated serum cholesterol to coronary heart disease is overwhelming. For example, atherosclerosis is a slowly progressive disease characterized by the accumulation of cholesterol within the arterial wall. Compelling evidence supports the concept that lipids deposited in atherosclerotic lesions are derived primarily from plasma LDL; thus, LDLs have popularly become known as the "bad" cholesterol. In contrast, HDL serum levels correlate inversely with coronary heart disease--indeed, high serum levels of HDL are regarded as a negative risk factor. It is hypothesized that high levels of plasma HDL are not only protective against coronary artery disease, but may actually induce regression of atherosclerotic plaques (e.g., see Badimon et al., 1992, Circulation 86 (Suppl. III):86-94). Thus, HDL have popularly become known as the "good" cholesterol. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

The invention also presents the use of the polynucleotides as elements on a substrate and provides methods for using the polynucleotides and polypeptides. Excerpt(s): This application claims benefit of provisional application Serial No. 60/323,784, filed Sep. 19, 2001. The present invention relates to a combination of polynucleotides which may be used to detect the differential expression of genes in human foam cells treated with oxidized low-density lipoprotein and/or lipopolysaccharide (LPS). In particular, the combination may be used in the diagnosis of conditions, diseases, and disorders associated with cardiovascular disease. Atherosclerosis and the associated coronary artery disease and cerebral stroke represent the most common cause of death in industrialized nations. Although certain key risk factors have been identified, a full molecular characterization that elucidates the causes and provides care for these associated diseases has not been achieved. Molecular characterization of growth and regression of atherosclerotic vascular lesions requires identification of the genes that contribute to formation of the lesion including growth, stability, dissolution, rupture and, most lethally, induction of occlusive vessel thrombus.

Moreover, chemokines may be involved in chronic diseases such as arthritis, asthma, and atherosclerosis. The present invention provides a new form of chemokine, designated as "Zchemo14." Excerpt(s): This application claims the benefit of U.S. Provisional application No. 60/291,778 (filed May 17, 2001), the contents of which are incorporated by reference. The present invention relates generally to a gene that encodes a new human protein. In particular, the present invention relates to a novel protein, designated "Zchemo14," and to nucleic acid molecules encoding Zchemo14. Chemotactic cytokines were originally identified in supernatants of stimulated leukocyte cell cultures, and were initially
216 Atherosclerosis
characterized through their chemotactic effects on a variety of leukocytes. Subsequent isolation of several chemotactic cytokines has led to the discovery of a family of structurally and functionally homologous molecules now known as "chemokines" (see, for example, Schnell, The Cytokine Handbook, (Academic Press 1994)). In vivo, chemokines have pro-inflammatory, pyrogenic, chemokinetic, myelosuppressive or hematopoietic effects; primarily, chemokines regulate inflammatory and immunoregulatory processes through their selective recruitment and activation of leukocytes. Chemokines are 8 to 16 kDa soluble basic proteins that are produced and released by a variety of cell types during an acute inflammatory response to injury, allergens, or microbial and viral infections. Moreover, chemokine involvement is apparent in some chronic inflammatory states such as arthritis, asthma, and eczema. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Identification of genes involved in restenosis and in atherosclerosis Inventor(s): Durrani, Sarfraz; (Arlington, VA), Epstein, Stephen E.; (Rockville, MD) Correspondence: Heller Ehrman White & McAuliffe LLP; Intellectual Property Department; Suite 300; 1666 K Street, N.W.; Washington; DC; 20006; US Patent Application Number: 20030170673 Date filed: October 2, 2002 Abstract: Methods are provided for estimating the risk of developing restenosis or of atherosclerosis in an individual. Methods and compositions for treating or preventing restenosis or atherosclerosis also are provided. Excerpt(s): Coronary artery disease is a disease that is endemic in Western society. In this disease the arteries that supply blood to the heart muscle become narrowed by deposits of fatty, fibrotic, or calcified material on the inside of the artery. The build up of these deposits is called atherosclerosis. Atherosclerosis reduces the blood flow to the heart, which starves the heart muscle of oxygen, leading to either/or angina pectoris (chest pain), myocardial infarction (heart attack), and congestive heart failure. One common treatment to clear arteries blocked by atherosclerosis is balloon angioplasty, more formally referred to as percutaneous transluminal coronary angioplasty (PTCA). This treatment involves opening up a blocked artery by inserting and inflating a small balloon, which compresses and rearranges the blocking plaque against the arterial wall. After deflation and removal of the balloon, the arterial lumen is enlarged, thereby improving blood flow. About one million angioplasty procedures are performed each year. In a significant number of angioplasty patients the treated artery narrows again within six months of the procedure in a process called restenosis. Restenosis begins soon after angioplasty, wherein the increased size of the vascular lumen (the open channel inside the artery) becomes gradually occluded by the proliferation of smooth muscle cells. Approximately 20 to 30% of all angioplasty patients experience restenosis to the extent that they must undergo repeated angioplasty or even coronary bypass surgery.

Box 3432; Ottawa; ON; K1P 6N9; CA Patent Application Number: 20030212007 Date filed: May 10, 2002 Abstract: A method is described for treating hypercholesterolemic atherosclerosis or for reducing total cholesterol while raising high-density lipoportoein cholesterol. It involves administering to a patient a substantially pure complex derived from flaxseed and containing secoisolariciresinol diglucoside (SDG), cinnamic acid glucosides and hydroxymethyl glutaric acid. Excerpt(s): This invention relates to a method for the use of a lignan complex isolated from flaxseed for the treatment of atherosclerosis, e.g. reducing or preventing the development of hypercholesterolemic atherosclerosis, for reducing total cholesterol and for raising HDL-C in blood. Hypercholesterolemia is a major risk factor for atherosclerosis (narrowing of the artery due to deposition of fat in the arterial wall) and related occlusive vascular diseases such as heart attack, stroke and other peripheral vascular diseases. Heart disease is the number one killer. Hypercholesterolemic atherosclerosis has been reported to be associated with oxidative stress increase in levels of reactive oxygen species (ROS), production of ROS by polymorphonuclear leukocytes as assessed by chemiluminescence (PMNL-CL), and a decrease in the antioxidant reserve. Pretreatment with antioxidants (vitamin E, probucol, garlic, purpurogallin, secoisolariciresinol diglucoside) reverses the effects of
218 Atherosclerosis
hypercholesterolemia. Flaxseed which is a rich source of.alpha.-linolenic acid and richest source of plant lignans has been shown to be effective in reducing hypercholesterolemic atherosclerosis without lowering serum levels of cholesterol. Using flaxseed which has very low.alpha.-linolenic acid, has shown that antiatherogenic activity of flaxseed is not due to.alpha.-linolenic acid but may be due to lignan component of flaxmeal. Presently the treatment of hypercholesterolemia and hypercholesterolemic atherosclerosis is to reduce hypercholesterolemia by using various lipid lowering agents such as bile acid sequestrant (cholestyramine, colestipol), nicotinic acid, HMG-CoA reductase inhibitor (lovastatin, provastatin, simvastatin, fluvastatin and atrovastatin) and gemfibrozil. Recently probucol which has both antioxidant and lipid lowering activity and vitamin E which has antioxidant activity have been used to prevent atherosclerosis and restenosis.

Excerpt(s): The present application is related to U.S. Patent Application No. 60/057,870, filed Sep. 2, 1997, the teachings of which are incorporated herein by reference. The present invention relates to methods for treating hypercholesterolemia, hyperlipidemia, and atherosclerosis in mammals by ingesting a stabilized rice bran derivative. Hypercholesterolemia is a condition with elevated levels of circulating total cholesterol, LDL-cholesterol and VLDL-cholesterol as per the guidelines of the Expert Panel Report of the National Cholesterol Educational Program (NCEP) of Detection, Evaluation of Treatment of high cholesterol in adults (see, Arch. Int. Med. (1988) 148, 36-39). In particular, high level of LDL and VLDL are positively associated with coronary arteriosclerosis while the high levels of high density lipoproteins (HDL) are negative risk factors. The role of LDL oxidation is gaining much attention in the literature. It is well documented that LDL becomes oxidatively stressed under pathological conditions and is no longer recognized by the LDL receptors. The oxidized LDL is taken up by macrophages within the subendothelial space, leading to the formation of fatty streaks which are the basis of most advanced lesions.

Excerpt(s): This application claims priority to U.S. Ser. No. 60/118,045 filed Feb. 1, 1999, which is incorporated by reference in its entirety. This invention relates to newly identified polynucleotides, polypeptides encoded by them and to the use of such polynucleotides and polypeptides, and to their production. More particularly, the polynucleotides and polypeptides of the present invention relate to a serine/threonine protein kinase, hereinafter referred to as hYAK3-2. The invention also relates to inhibiting or activating the action of such polynucleotides and polypeptides. A number of polypeptide growth factors and hormones mediate their cellular effects through a signal transduction pathway. Transduction of signals from the cell surface receptors for these ligands to intracellular effectors frequently involves phosphorylation or dephosphorylation of specific protein substrates by regulatory protein serine/threonine kinases (PSTK) and phosphatases. Serine/threonine phosphorylation is a major mediator of signal transduction in multicellular organisms. Receptor-bound, membranebound and intracellular PSTKs regulate cell proliferation, cell differentiation and signalling processes in many cell types.

TREATMENT OF OBESITY, the whole of which are hereby incorporated by reference herein. AMP-activated protein kinase (AMPK) is a cytoplasmic enzyme that has been shown to exist in both the liver and skeletal muscle. As its name indicates, AMPK is activated by increasing levels of AMP and, secondarily, by an increase in the ratio of AMP to ATP in the cell. AMP levels rise in the cell as ATP is hydrolyzed to ADP and Pi. Two molecules of ADP, through the action of myokinase, also known as adenylate kinase, produce one molecule of ATP and one molecule of AMP. In addition to its activation by AMP, AMPK is activated through phosphorylation by an upstream kinase called AMPK kinase (AMPKK). AMP also allosterically activates AMPKK. Phosphorylation of AMPK by AMPKK makes it a poor substrate for phosphatases. All these factors combined together make AMPK very sensitive to minimal fluctuations in cellular AMP levels. AMPK has several known substrates, specifically enzymes that it can phosphorylate and modulate. In the liver, AMPK has been shown to phosphorylate hydroxymethyl glutaryl CoA (HMGCOA) reductase and acetyl CoA carboxylase (ACC), inhibiting the actions of both enzymes. Reducing HMGCOA reductase activity inhibits cholesterol synthesis, and reducing ACC activity decreases the generation of malonyl CoA, an intermediate in fatty acid synthesis. In skeletal muscle, AMPK also is an inhibitor of carnitine palmitoyl transferase I, which regulates the uptake of fatty acids into mitochondria where they are oxidized. In addition, AMPK has been shown to increase glucose transport into the muscle. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

The instant invention is in the field of Advanced Glycation End-products (AGEs), their formation, detection, identification, inhibition, and inhibitors thereof. Nonenzymatic glycation by glucose and other reducing sugars is an important post-translational modification of proteins that has been increasingly implicated in diverse pathologies. Irreversible nonenzymatic glycation and crosslinking through a slow, glucose-induced process may mediate many of the complications associated with diabetes. Chronic hyperglycemia associated with diabetes

can cause chronic tissue damage which can lead to complications such as retinopathy, nephropathy, and atherosclerotic disease. (Cohen and Ziyadeh, 1996, J. Amer. Soc. Nephrol. 7:183-190). It has been shown that the resulting chronic tissue damage associated with long-term diabetes mellitus arise in part from in situ immune complex formation by accumulated immunoglobulins and/or antigens bound to long-lived structural proteins that have undergone Advanced Glycosylation End-product (AGE) formation. via non-enzymatic glycosylation (Brownlee et al., 1983, J. Exp. Med. 158:17391744). The primary protein target is thought to be extra-cellular matrix associated collagen. Nonenzymatic glycation of proteins, lipids, and nucleic acids may play an important role in the natural processes of aging. Recently protein advanced glycation has been associated with.beta.-amyloid deposits and formation of neurofibrillary tangles in Alzheimer disease, and possibly other neurodegenerative diseases involving amyloidosis (Colaco and Harrington, 1994, NeuroReport 5: 859-861). Glycated proteins have also been shown to be toxic, antigenic, and capable of triggering cellular injury responses after uptake by specific cellular receptors (see for example, Vlassara, Bucala & Striker, 1994, Lab.

Novel indazole peptidomimetics as thrombin receptor antagonists Inventor(s): Maryanoff, Bruce E.; (Forest Grove, PA), Pandey, Anjali; (Fremont, CA), Scarborough, Robert M.; (Half Moon Bay, CA), Zhang, Han-Cheng; (Lansdale, PA) Correspondence: AUDLEY A. CIAMPORCERO JR.; JOHNSON & JOHNSON; ONE JOHNSON & JOHNSON PLAZA; NEW BRUNSWICK; NJ; 08933-7003; US Patent Application Number: 20030199455 Date filed: March 31, 2003 Abstract: The invention is directed to novel indazole peptidomimetic compounds which are useful as thrombin receptor antagonists for the treatment of diseases associated with thrombosis, restenosis, hypertension, heart failure, arrhythmia, inflammation, angina, stroke, atherosclerosis, ischemic conditions, Angiogenesis related disorders, cancer, and neurodegenerative disorders. Pharmaceutical compositions comprising the substituted indazole peptidomimetics of the present invention and methods of treating conditions mediated by the thrombin receptor are also disclosed. Excerpt(s): This invention relates to certain novel thrombin receptor antagonists, their synthesis and their use for the treatment of diseases associated with thrombosis, restenosis, hypertension, heart failure, arrhythmia, inflammation, angina, stroke, atherosclerosis, ischemic conditions, Angiogenesis related disorders, cancer, and neurodegenerative disorders. Thrombin is an important serine protease in hemostasis and thrombosis. One of the key actions of thrombin is cellular modulation via receptor activation. A functional human thrombin receptor (PAR-1), cloned by Coughlin in 1991 (T. -K. Vu, Cell 1991, 64, 1057), was found to be a member of the G-protein coupled
Patents 225
receptor (GPCR) superfamily. The receptor activation putatively occurs by N-terminal recognition and proteolytic cleavage at the Arg-41/Ser42 peptide bond to reveal a truncated N-terminus. This new receptor sequence, which has an SFLLRN (Ser-Phe-LeuLeu-Arg-Asn) N-terminus acting as a tethered ligand to recognize a site on the receptor, can trigger activation and signal transduction leading to platelet aggregation. Since 1991, three other protease-activated receptors with extensive homology to the thrombin receptor, "PAR-2" (S. Nystedt, Proc. Natl. Acad. Sci USA 1994, 91, 9208), "PAR-3" (H. Ishihara, Nature 1997, 386, 502), and "PAR4" (W. -F. Xu, Proc. Natl. Acad. Sci USA 1998, 95, 6642), have been cloned. Thrombin receptor (PAR-1) specific antibody-induced blockade of the platelet thrombin receptor has shown efficacy against arterial thrombosis in vivo (J. J. Cook Circulation 1995, 91, 2961). Hence, antagonists of the thrombin receptor (PAR-1) are useful to block these protease-activated receptors and, as such, may be used to treat platelet mediated thrombotic disorders such as myocardial infarction, stroke, restenosis, angina, atherosclerosis, and ischemic conditions. The thrombin receptor (PAR-1) has also been identified on other cell types: endothelial, fibroblast, renal, osteosarcoma, smooth muscle, myocytes, tumor, and neuronal/glia. Thrombin activation of endothelial cells upregulates P-selectin to induce polymorphonuclear leukocyte adhesion--an inflammatory response of the vessel wall (Y. Sugama, J. Cell Biol. 1992, 119, 935). In fibroblasts, thrombin receptor (PAR-1) activation induces proliferation and transmission of mitogenic signals (D. T. Hung, J. Cell Biol. 1992, 116, 827). Thrombin has been implicated in osteoblast proliferation through its activation of osteoblast cells (D. N. Tatakis, Biochem. Biophys. Res. Commun. 1991, 174, 181). Thrombin has been implicated in the regulation and retraction of neurons (K. Jalink, J. Cell. Biol. 1992, 118, 411). Therefore, in this context, the antagonist compounds of this invention may also be useful against inflammation, osteoporosis, Angiogenesis related disorders, cancer, neurodegenerative disorders, hypertension, heart failure, arrhythmia, glomerulonephritis.

226 Atherosclerosis
Excerpt(s): The present invention relates to a novel protein having a lecithin-cholesterol acyltransferase-like activity etc. and a DNA coding for the protein. Cholesterol is an important lipid constituting the animal cell membrane and defining its character. Moreover, it is a precursor of steroid hormones, thus being a substance essential to animal life. However, due to the recent changes in dietary habit and ecology, arteriosclerosis and other adult diseases arising from pathological intracellular accumulation of cholesterol are now presenting a serious problem so that elucidation of the mechanisms of cholesterol metabolism in the body is being awaited. In the efflux of cholesterol from the peripheral cells, high density lipoprotein (hereinafter sometimes referred to briefly as HDL) is suspected to play a cardinal role and this assumption has been supported by the epidemiologic finding of an inverse correlation between risk for coronary artery disease and plasma HDL levels and the experimental finding that HDL in culture medium stimulates cholesterol efflux from cells and decreases the intracellular concentration of cholesterol (Journal of Lipid Research, 37, 2473, 1996). In the reverse cholesterol transport system, lecithin-cholesterol acyltransferase (hereinafter sometimes referred to briefly as LCAT) is involved to a significant extent.

Despite the early

discovery of insulin and its subsequent widespread use in the treatment of diabetes, and the later discovery of, and use of, sulfonylureas (e.g. Chlorpropamide.TM. (Pfizer), Tolbutamide.TM. (Upjohn), Acetohexamide.TM. (E. I. Lilly), Tolazamide.TM. (Upjohn), and biguanides (e.g. Phenformin.TM. (Ciba Geigy), and Mefformin.TM. (G. D. Searle)) as oral hypoglycemic agents, therapeutic regimens for the treatment of diabetes remain less than satisfactory. The use of insulin, necessary in about 10% of diabetic patients in which synthetic hypoglycemic agents are not effective (Type 1 diabetes, insulin dependent diabetes mellitus), requires multiple daily doses, usually by self-injection. Determination of the proper dosage of insulin requires frequent estimations of sugar levels in the urine or blood. The administration of an excess dose of insulin causes hypoglycemia, with effects ranging from mild abnormalities in blood glucose to coma, or even death. Treatment of non-insulin dependent diabetes mellitus (Type 2 diabetes) usually consists of a combination of diet, exercise, oral agents, e.g., sulfonylureas, and, in more severe cases, insulin. However, clinically available hypoglycemic agents can have other side effects that limit their use. In any event, where one of these agents may fail in an individual case, another may succeed. A continuing need for hypoglycemic agents, which may have fewer side effects or succeed where others fail, is clearly evident. Atherosclerosis, a disease of the arteries, is recognized to be the leading cause of death in the United States and Western Europe. The pathological sequence leading to atherosclerotic development and occlusive heart disease is well known. The earliest stage in this sequence is the formation of "fatty streaks" in the carotid, coronary, and cerebral arteries, and in the aorta. These lesions are yellow in color due to the presence of lipid deposits found principally within smooth-muscle cells and in macrophages of the intima layer of the arteries and aorta. It is further postulated that most of the cholesterol found within the fatty streaks, in turn, gives rise to development of the socalled "fibrous plaque", which consists of accumulated intimal smooth muscle cells laden with lipid and surrounded by extra-cellular lipid, collagen, elastin, and proteoglycans. These cells, plus matrix, form a fibrous cap that covers a deeper deposit of cell debris and more extra cellular lipid, which comprises primarily free and esterified cholesterol. The fibrous plaque forms slowly, and is likely in time to become calcified and necrotic, advancing to the so-called "complicated lesion" which accounts for the arterial occlusion and tendency toward mural thrombosis and arterial muscle spasm that characterize advanced atherosclerosis.

The present invention relates to promoting and enhancing whole body health or overall systemic health in humans and other animals, by use of topical oral compositions comprising an antimicrobial agent, in particular stannous salts, such as stannous fluoride and stannous chloride in combination with a polymeric mineral surface active agent such as condensed polyphosphates or polyphosphonates. In addition to providing a spectrum of intraoral benefits including control of breath malodor, control of dental plaque growth and metabolism, reduced gingivitis, decreased progression to periodontal disease, reductions in dentinal hypersensitivity and reduced coronal and root dental caries, topical administration of the present compositions to the oral cavity surprisingly provides benefits to systemic health. In particular, the present invention relates to methods of using the present topical oral compositions to reduce the risk in development of cardiovascular disease, stroke, atherosclerosis, diabetes, severe respiratory infections, premature births and low birth weight, post-partum dysfunction in neurologic and developmental functions, and associated increased risk of mortality. Recent research has revealed that periodontal disease or gum disease may be a far more serious threat to overall systemic health than previously realized. Periodontitis, a common form of periodontal disease, is a tissue destructive process resulting from the accumulation of pathogenic bacteria along the gingival margin and the consequent tissue destructive host response to these pathogens. The presence of periodontitis can result in the release of bacterial pathogens and/or bacterial toxins into the bloodstream. The host responses to the presence of these bacterial pathogens and/or toxins in the bloodstream may contribute to the development of atherosclerosis (heart disease), increase the risk of premature, underweight babies; and pose a serious threat to people whose health is compromised by diabetes, respiratory diseases, stroke and bacteremia bacteria in the blood).

The present invention relates to compounds that modulate the PPAR.gamma. receptor and are useful in the diagnosis and treatment of type II diabetes (and complications thereof), hypercholesterolemia (and related disorders associated with abnormally high or low plasma lipoprotein or triglyceride levels) and inflammatory disorders. The peroxisome proliferator-activated receptors (PPARs) are transducer proteins belonging to the steroid/thyroid/retinoid receptor superfamily. The PPARs were originally identified as orphan receptors, without known ligands, but were named for their ability to mediate the pleiotropic effects of fatty acid peroxisome proliferators. These receptors function as ligand-regulated transcription factors that control the expression of target genes by binding to their responsive DNA sequence as heterodimers with RXR. The target genes encode enzymes involved in lipid metabolism and differentiation of adipocytes. Accordingly, the discovery of transcription factors involved in controlling lipid metabolism has provided insight into regulation of energy homeostasis in vertebrates, and further provided targets for the development of therapeutic agents for disorders such as obesity, diabetes and dyslipidemia.

that inhibit cholesteryl ester transfer protein (CETP), also known as plasma lipid transfer protein-I. Numerous studies have demonstrated that a low plasma concentration of high density lipoprotein (HDL) cholesterol is a powerful risk factor for the development of atherosclerosis (Barter and Rye, Atherosclerosis, 121, 1-12 (1996)). HDL is one of the major classes of lipoproteins that function in the transport of lipids through the blood. The major lipids found associated with HDL include cholesterol, cholesteryl ester, triglycerides, phospholipids and fatty acids. The other classes of lipoproteins found in the blood are low density lipoprotein (LDL) and very low density lipoprotein (VLDL). Since low levels of HDL cholesterol increase the risk of atherosclerosis, methods for elevating plasma HDL cholesterol would be therapeutically beneficial for the treatment of atherosclerosis and other diseases associated with accumulation of lipid in the blood vessels. These diseases include, but are not limited to, coronary heart disease, peripheral vascular disease, and stroke. Atherosclerosis underlies most coronary artery disease (CAD), a major cause of morbidity and mortality in modern society. High LDL cholesterol (above 180 mg/dl) and low HDL cholesterol (below 35 mg/dl) have been shown to be important contributors to the development of atherosclerosis. Other diseases, such as peripheral vascular disease, stroke, and hypercholesterolaemia are negatively affected by adverse HDL/LDL ratios. Inhibition of CETP by the subject compounds is shown to effectively modify plasma HDL/LDL ratios, and to check the progress and/or formation of these diseases.

The ability of a cell to rapidly and appropriately respond to the array of external and internal signals it continually receives is of critical importance in maintaining a balance between these processes (Rozengurt, Current Opinion in Cell Biology 1992, 4, 161-5; Wilks, Progress in Growth Factor Research 1990, 2, 97-111). The loss of control over cellular regulation can often lead to aberrant cell function or death, often resulting in a disease state in the parent organism. The protein kinases represent a large family of proteins which play a central role in the regulation of a wide variety of cellular processes and maintaining control over cellular function (Hanks, et al., Science 1988, 241, 42-52). A partial list of such kinases includes ab1, ATK, bcr-ab1, Blk, Brk, Btk, c-kit, c-met, c-src, CDK1, CDK2, CDK4, CDK6, cRaf1, CSF1R, CSK, EGFR, ErbB2, ErbB3, ErbB4, ERK, Fak, fes, FGFR1, FGFR2, FGFR3, FGFR4, FGFR5, Fgr, FLK-4, flt-1, Fps, Frk, Fyn, Hck, IGF-1R, INS-R, Jak, KDR, Lck, Lyn, MEK, p38, PDGFR, PIK, PKC, PYK2, ros, tie.sub.1, tie.sub.2, TRK,Yes, and Zap70.

Sulfonylaminocarboxylic acid N-arylamides as guanylate cyclase activators Inventor(s): Schindler, Ursula; (Bad Soden, DE), Schoenafinger, Karl; (Alzenau, DE), Strobel, Hartmut; (Liederbach, DE) Correspondence: FINNEGAN, HENDERSON, FARABOW, GARRETT & DUNNER; LLP; 1300 I STREET, NW; WASHINGTON; DC; 20005; US Patent Application Number: 20030171352 Date filed: January 24, 2003 Abstract: The present invention relates to compounds of the formula I 1in which A.sup.1, A.sup.2, R.sup.2 and R.sup.3 have the meanings indicated in the claims, which are valuable pharmaceutical active compounds for the therapy and prophylaxis of diseases, for example of cardiovascular disorders such as high blood pressure, angina pectoris, cardiac insufficiency, thromboses or atherosclerosis. The compounds of the formula I have the ability to modulate the endogenous production of cyclic guanosine monophosphate (cGMP) and are generally suitable for the therapy and prophylaxis of disease states which are associated with a disturbed cGMP balance. The invention relates to the use of compounds of the formula I for the therapy and prophylaxis of the designated disease states and for the production of pharmaceuticals therefor, novel compounds of the formula I, pharmaceutical preparations comprising them and processes for their preparation. Excerpt(s): in which A.sup.1, A.sup.2, R.sup.2 and R.sup.3 have the meanings indicated below, which are valuable pharmaceutical active compounds for the therapy and prophylaxis of diseases, for example of cardiovascular disorders such as high blood pressure, angina pectoris, cardiac insufficiency, thromboses or atherosclerosis. The compounds of the formula I have the ability to modulate the endogenous production of cyclic guanosine monophosphate (cGMP) and are generally suitable for the therapy and prophylaxis of disease states which are associated with a disturbed cGMP balance. The invention relates to the use of compounds of the formula I for the therapy and prophylaxis of the designated disease states and for the production of pharmaceuticals therefor, novel compounds of the formula I, pharmaceutical preparations comprising them and processes for their preparation. cGMP is an important intracellular messenger,
Patents 233
which elicits a number of pharmacological effects by means of the modulation of cGMPdependent protein kinases, phosphodiesterases and ion channels. Examples are smooth muscle relaxation, the inhibition of platelet activation and the inhibition of smooth muscle cell proliferation and leukocyte adhesion. cGMP is produced by particulate and soluble guanylate cyclases as a response to a number of extracellular and intracellular stimuli. In the case of the particulate guanylate cyclases, the stimulation essentially takes place by means of peptidic messenger substances, such as the atrial natriuretic peptide or the cerebral natriuretic peptide. The soluble guanylate cyclases (sGC), which are cytosolic, heterodimeric heme proteins, however, are essentially regulated by a family of low molecular weight, enzymatically formed factors. The most important stimulant is nitrogen monoxide (NO) or a closely relates species. The importance of other factors such as carbon monoxide or the hydroxyl radical is still largely unclarified. The binding of NO to the heme with formation of a pentacoordinated heme-nitrosyl complex is discussed as an activation mechanism of activation by NO. The release associated therewith of the histidine which is bound to the iron in the basal state converts the enzyme into the activated conformation. Active soluble guanylate cyclases are each composed of one.alpha.- and one.beta.-subunit. Several subtypes of the subunits have been described, which differ from one another with respect to sequence, tissue-specific distribution and expression in various stages of development. The subtypes.alpha.sub.1 and.beta.sub.1 are mainly expressed in the brain and lung, while.beta.sub.2 is especially found in liver and kidney. The subtype.alpha.sub.2 was detected in human fetal brain. The subunits designated as.alpha.sub.3 and.beta.sub.3 were isolated from human brain and are homologous to.alpha.sub.1 and.beta.sub.1. More recent studies point to an.alpha.sub.2i subunit, which contains an insert in the catalytic domain. All subunits show great homology in the area of the catalytic domain. The enzymes presumably contain one heme per heterodimer, which is bonded via.beta.sub.1-Cys-78 and/or.beta.sub.1-His-105 and is part of the regulatory center.

234 Atherosclerosis
Excerpt(s): This application claims the benefit of U.S. Provisional Application No. 60/330,359, filed Oct. 18, 2001. Thrombin is known to have a variety of activities in different cell types and thrombin receptors are known to be present in such cell types as human platelets, vascular smooth muscle cells, endothelial cells and fibroblasts. It is therefore expected that thrombin receptor antagonists will be useful in the treatment of thrombotic, inflammatory, atherosclerotic and fibroproliferative disorders, as well as other disorders in which thrombin and its receptor play a pathological role. Thrombin receptor antagonist peptides have been identified based on structure-activity studies involving substitutions of amino acids on thrombin receptors. In Bernatowicz et al, J. Med. Chem., 39 (1996), p. 4879-4887, tetra- and pentapeptides are disclosed as being potent thrombin receptor antagonists, for example N-trans-cinnamoyl-p-fluoroPhe-- pguanidinoPhe-Leu-Arg-NH.sub.2 and N-trans-cinnamoyl-p-fluoroPhe-p-guanidinoPhe-Leu-Arg-Arg-NH.sub.2.

Treatment of post-angioplasty restenosis and atherosclerosis with Ras antagonists Inventor(s): George, Jakob; (Tel Aviv-Yafo, IL), Keren, Gad; (Kiryat Ono, IL), Kloog, Yoel; (Herzlia, IL) Correspondence: LERNER, DAVID, LITTENBERG,; KRUMHOLZ & MENTLIK; 600 SOUTH AVENUE WEST; WESTFIELD; NJ; 07090; US Patent Application Number: 20030203942 Date filed: April 22, 2003 Abstract: Disclosed are methods for inhibiting Ras activity such as cell proliferation associated with vascular injury such as post-angioplasty restenosis and atherosclerosis. Preferred Ras antagonists are S-trans-trans farnesylthiosalicylic acid (FTS) and structurally related compounds (or analogs) thereof. Excerpt(s): This application is a continuation of U.S. application Ser. No. 10/023,545, filed Dec. 18, 2001, which is a continuation-in-part of U.S. application Ser. No. 09/597,332, filed Jun. 19, 2000, which claims priority under 35 U.S.C.sctn. 119(e) from U.S. Application No. 60/140,192, filed Jun. 18, 1999. The contents of these two applications are hereby incorporated herein by reference in their entireties. The present invention relates to the inhibition of the onset of or the treatment of non-malignant diseases, and particularly diseases having pathologies involving Ras-induced proliferation of cells. Autoimmune diseases include disorders involving dysfunction of the immune system, which mediates tissue damage. Any organ may be affected by such processes through precipitation of immune complexes, cellular immunity, or inappropriate generation or action of immuno-hormones such as cytokines. Epidemiologically, autoimmune diseases are significant because of the numbers of patients that they affect and the serious morbidity and mortality that they cause. Common chronic systemic diseases in this group include diabetes mellitus, thyroid disease, rheumatoid arthritis, systemic lupus erythmatosus (SLE), primary antiphospholipid syndrome (APS), and a variety of diseases that affect the central nervous system. Neurological autoimmune diseases include disorders specific to the nervous system such as myasthenia gravis, Lambert Eaton myasthenic syndrome, Guillain-Barre syndrome, polymyositis, and multiple sclerosis. In addition, there are neurological complications of the systemic autoimmune diseases. Factors predisposing to autoimmune diseases include genetic predisposition and environmental agents such
Patents 235
as certain infections and pharmaceutical products. Such factors result in pathological activation of the immune response in susceptible individuals, which is generally controlled by T lymphocytes (T cells). The activation of T cells and B subtypes, involves a complex interaction of cell surface receptors resulting in equally complex signal transduction pathways which eventually affect gene regulation. Full activation of lymphocytes requires parallel stimulation of several signal transduction pathways. See Ohtsuka et al., Biochim. Biophys. Acta. 1310:223-232 (1996).

Use of pro-apoptotic factors in treatment of atherosclerosis Inventor(s): Arvelo, Maria B.; (Quincy, MA), Ferran, Christiane; (West Roxbury, MA) Correspondence: CLARK & ELBING LLP; 101 FEDERAL STREET; BOSTON; MA; 02110; US Patent Application Number: 20030207838 Date filed: June 13, 2003 Abstract: The present invention features a novel method of treating vascular disease that involves modifying smooth muscle cells to express a gene encoding a protein having both anti-inflammatory and pro-apoptotic activity. Preferably, the protein of the invention also has an anti-proliferative effect in smooth muscle cells. In general, the method is useful in preparing vascularized organs and vessels for transplant into a patient. Alternatively, the present invention can be applied to treat atherosclerotic lesions in damaged vessels. Excerpt(s): The present application claims benefit to Provisional application No. 60/177,535 filed Jan. 21, 2000, the entire contents of which are incorporated herein by reference. The present invention relates to the field of vascular disease. Vascular disease is the most common cause of morbidity and mortality in the western world, surpassing any other single degenerative disease. The fundamental pathology of vascular disease is an abnormal accumulation of cells within the subintimal space below the surface of the endothelial cell lining, resulting in a decrease in lumen size and tissue perfusion. This accumulation is due to the proliferation and/or migration of smooth muscle cells, and/or inflammatory cells into the intimal layer of a vessel, resulting in restricted blood flow through that vessel, i.e. neointimal occlusive lesions.

In addition to LOCATORPlus, in collaboration with authors and publishers, the National Center for Biotechnology Information (NCBI) is currently adapting biomedical books for the Web. The books may be accessed in two ways: (1) by searching directly using any search term or phrase (in the same way as the bibliographic database PubMed), or (2) by following the links to PubMed abstracts. Each PubMed abstract has a "Books" button that displays a facsimile of the abstract in which some phrases are hypertext links. These phrases are also found in the books available at NCBI. Click on hyperlinked results in the list of books in which the phrase is found. Currently, the majority of the links are between the books and PubMed. In the future, more links will be created between the books and other types of information, such as gene and protein sequences and macromolecular structures.

[email protected] PRICE: $125.00, plus shipping and handling. ISBN: 089603755X. Summary: With over ten million diagnosed patients and another five million undiagnosed, diabetes mellitus and its complications is a major public health problem that will assume epidemic proportions as the population grows older. This chapter on diabetes and atherosclerosis (hardening and narrowing of the arteries) is from a textbook that offers physicians practical knowledge about cardiovascular disease and diabetes. This chapter is in Part I, which focuses on pathophysiology, including the mechanisms and risk factors for diabetic cardiovascular disease. The author notes that macrovascular (large vessel) disease is the leading cause of mortality (death) and morbidity (illness) in diabetes. The author discusses endothelial (the cells that line the body cavity and the cardiovascular system) dysfunction, the mechanisms of foam cell formation, the role of humoral immunity and macrophage activation, abnormalities in platelet function, coagulation, and fibrinolysis, particularly as they contribute to thrombus (clot) formation. The author provides updated information concerning factors associated with diabetes that may accelerate the development of atherosclerosis and thrombosis and contribute to acute clinical events. 1 figure. 227 references.

[email protected]. PRICE: $89.00 plus shipping and handling. Summary: This patient education videotape program reviews the problem of erectile dysfunction (impotence) and diabetes mellitus. The program defines erectile dysfunction (ED) as the consistent inability to get and maintain an erection. The program first explores the physiology of erections (how they happen), including the need for mental and physical stimulation, nerve impulses in the brain, and responses in muscles, fibrous tissues, and veins and arteries. The program offers a diagram and the use of a balloon to describe how an erection happens, the anatomy of the corpera cavernosa, and the role of nitrous oxide as a neurochemical transmitter. Age is noted as a factor in ED, and men with diabetes tend to develop ED 10 to 15 years earlier than
254 Atherosclerosis
men who do not have diabetes. The program notes that psychological factors (stress, depression, guilt, and performance anxiety) can cause 10 to 15 percent of ED; a series of self test questions are included for viewers to determine if psychological factors may play a role in their own ED. For men with diabetes, nerve damage (peripheral neuropathy) is the most likely culprit for causing ED; damage to the blood vessels (atherosclerosis) is another cause. Poor blood glucose control is the most important factor in both of these problems. The program includes a section noting the impact of drugs (including alcohol and nicotine) on ED. The program outlines the steps in diagnosing erectile problems, including first admitting that there is a problem, talking with a doctor, undergoing diagnostic tests, and participating in treatment. The final section reviews treatment options, reiterating the importance of good blood glucose control and describing the use of drug therapy (Viagra), vacuum erectile systems, self injection, and surgery (blood vessel repair and penile implants). The program includes drawings, graphics, and footage of patients and their physicians through the diagnosis and treatment processes. •

The model it presents of the cause of diabetes hypothesizes that an environmental trigger in a genetically susceptible person causes inflammation that eventually destroys the cells of the pancreas and leads to a reduction in insulin. The video highlights diabetes symptoms, including polyuria, polydipsia, polyphagia, weight loss, and blurred vision. It explains why people with diabetes consume so much fluid and why they have increased urination. Among the other topics covered are diabetes education, medications and their side effects, diabetic retinopathy, cardiovascular disease, atherosclerosis, foot problems and neuropathy, and renal failure. The video includes numerous comments from physicians and patients.

[email protected]. PRICE: $39.00 plus shipping and handling. Summary: This video, which was developed by the American Heart Association, is intended to help people with diabetes become better informed about heart disease. The video points out that people who have diabetes have a increased risk of developing problems that involve the cardiovascular system. These problems include atherosclerosis (the build up of fatty acids in arteries) and hypertension (high blood pressure). High levels of glucose can damage arteries and increase the likelihood of hypertension and atherosclerosis. In some cases, hypertension may be controlled with changes in lifestyle, such as losing weight, reducing salt intake, and exercising. When lifestyle changes are insufficient to control hypertension, medication is used. The video notes that people must not treat hypertension with over the counter medicines or prescriptions from a friend because they may worsen diabetes or its related conditions.
Multimedia 255
Many of the things that help to manage diabetes can also be effective in reducing the risk of heart disease. Self monitoring of blood glucose, eating healthfully, exercising, taking medication as needed, and educating oneself are each important. The video concludes that people with diabetes can successfully control blood glucose levels and significantly lower the risk of heart disease by making appropriate lifestyle changes and working with health care professionals. An accompanying brochure focuses on topics addressed in the video. The video is available in English or Spanish. (AA-M).

Atherosclerosis and Coronary Artery Disease in SLE Source: Lupus News. 20(2): 6-7. Spring 2000. Contact: Available from Lupus Foundation of America. 1300 Piccard Drive, Suite 200, Rockville, MD 20850-4303. (800) 558-0121 or (301) 670-9292. Fax (301) 670-9486. Website: www.lupus.org/lupus. Summary: This newsletter article provides health professionals and people who have systemic lupus erythematosus (SLE) with information on atherosclerosis and coronary artery disease in SLE. Accelerated atherosclerosis has become recognized as one of the causes of illness and death in people with SLE. The prevalence of coronary artery disease in lupus varies, and deaths from atherosclerosis tend to occur in older people who have had lupus for longer periods of time. Although mortality rates from atherosclerosis appear low, people who have lupus and atherosclerosis are usually younger than the typical person with atherosclerosis. Routine tests such as stress testing and electrocardiograms used to detect early coronary artery disease may be unreliable in people who have lupus, and some people may not be able to undergo the exercise necessary to complete the tests properly. Known risk factors for coronary disease in the general population, including hypertension, diabetes, and lipid disorders, may be magnified in people who have lupus. These factors, and older age and postmenopausal status, are linked with coronary artery disease in people who have lupus. SLE itself also appears to be a risk factor for coronary disease. Awareness of the issue of lupus related coronary artery disease by both the physician and patient is important.

CHAPTER 10. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for atherosclerosis. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a non-profit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI Advice for the Patient can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with atherosclerosis. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.). The

Coffee Break: Tutorials for Biologists20 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.21 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.22 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.
•
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
The Genome Project and Atherosclerosis In the following section, we will discuss databases and references which relate to the Genome Project and atherosclerosis. Online Mendelian Inheritance in Man (OMIM) The Online Mendelian Inheritance in Man (OMIM) database is a catalog of human genes and genetic disorders authored and edited by Dr. Victor A. McKusick and his colleagues at Johns Hopkins and elsewhere. OMIM was developed for the World Wide Web by the National Center for Biotechnology Information (NCBI).23 The database contains textual information, pictures, and reference information. It also contains copious links to NCBI’s Entrez database of MEDLINE articles and sequence information.
20 Adapted 21
from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 22 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process. 23 Adapted from http://www.ncbi.nlm.nih.gov/. Established in 1988 as a national resource for molecular biology information, NCBI creates public databases, conducts research in computational biology, develops software tools for analyzing genome data, and disseminates biomedical information--all for the better understanding of molecular processes affecting human health and disease.
274 Atherosclerosis
To search the database, go to http://www.ncbi.nlm.nih.gov/Omim/searchomim.html. Type “atherosclerosis” (or synonyms) into the search box, and click “Submit Search.” If too many results appear, you can narrow the search by adding the word “clinical.” Each report will have additional links to related research and databases. In particular, the option “Database Links” will search across technical databases that offer an abundance of information.

The databases available are listed in the drop box next to “Search.” Enter “atherosclerosis” (or synonyms) into the search box and click “Go.” Jablonski’s Multiple Congenital Anomaly/Mental Retardation (MCA/MR) Syndromes Database24 This online resource has been developed to facilitate the identification and differentiation of syndromic entities. Special attention is given to the type of information that is usually limited or completely omitted in existing reference sources due to space limitations of the printed form. At http://www.nlm.nih.gov/mesh/jablonski/syndrome_toc/toc_a.html, you can search across syndromes using an alphabetical index. Search by keywords at http://www.nlm.nih.gov/mesh/jablonski/syndrome_db.html. The Genome Database25 Established at Johns Hopkins University in Baltimore, Maryland in 1990, the Genome Database (GDB) is the official central repository for genomic mapping data resulting from the Human Genome Initiative. In the spring of 1999, the Bioinformatics Supercomputing Centre (BiSC) at the Hospital for Sick Children in Toronto, Ontario assumed the management of GDB. The Human Genome Initiative is a worldwide research effort focusing on structural analysis of human DNA to determine the location and sequence of the estimated 100,000 human genes. In support of this project, GDB stores and curates data generated by researchers worldwide who are engaged in the mapping effort of the Human Genome Project (HGP). GDB’s mission is to provide scientists with an encyclopedia of the human genome which is continually revised and updated to reflect the current state of scientific knowledge. Although GDB has historically focused on gene mapping, its focus will broaden as the Genome Project moves from mapping to sequence, and finally, to functional analysis. To access the GDB, simply go to the following hyperlink: http://www.gdb.org/. Search “All Biological Data” by “Keyword.” Type “atherosclerosis” (or synonyms) into the search box, and review the results. If more than one word is used in the search box, then separate each one with the word “and” or “or” (using “or” might be useful when using synonyms).

APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on atherosclerosis can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to atherosclerosis. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to atherosclerosis. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “atherosclerosis”:

You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on atherosclerosis. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/. To search this database, go to http://chid.nih.gov/detail/detail.html. In particular, you can use the advanced search options to look up pamphlets, reports, brochures, and information kits.

Summary: Cholesterol is a fat-like substance in the blood that the body needs for many essential functions. High blood cholesterol levels increase the risk of atherosclerosis, a buildup of fatty deposits in the arteries, which makes it difficult for blood to travel through the body. This simple brochure asks readers to consider their current cholesterol levels and to think about making cholesterol control part of an overall plan for better health. The brochure outlines the importance of better cholesterol management. The brochure also has blank space for readers to record their thoughts about lowering their cholesterol and how to overcome the typical obstacles to making changes in one's habits. The brochure concludes with a brief list of resources for readers wanting additional information.

Thinking About Lowering Your Cholesterol Source: Midland, MI: Health Enhancement Systems. 1999. 2 p. Contact: Available from Health Enhancement Systems. P.O. Box 1035, Midland, MI 48641-1035. (800) 326-2317. Fax (517) 839-0025. PRICE: $0.68 each for a pack of 10 to 50 brochures; bulk quantities available; plus shipping and handling. Item number HESHC1. Summary: This brochure guides readers through the process of thinking about lowering their cholesterol. Cholesterol is a fat like substance that the body needs for many functions, and the liver produces all the cholesterol the body requires. Cholesterol and blood do not mix, so cholesterol needs to be carried in the blood, by fat and protein, in packages called lipoproteins. High density lipoprotein takes cholesterol out of the bloodstream and back to the liver, but low density lipoprotein leaves cholesterol deposits in the walls of the arteries. The brochure begins by explaining the importance of reducing high cholesterol levels. High blood cholesterol levels increase the risk of atherosclerosis, a buildup of fatty deposits in the arteries. This can result in chest pain, heart attacks, and strokes. In addition, the brochure asks a series of questions that helps readers think about lowering cholesterol.

Erectile Dysfunction Source: American Family Physician. 60(4): 1169. September 15, 1999. Contact: Available from American Academy of Family Physicians. 11400 Tomahawk Creek Parkway, Leawood, KS 66211-2672. (800) 274-2237. Website: www.aafp.org. Summary: With the introduction of effective drug treatment for erectile dysfunction (ED, previously called impotence), more men are seeking treatment. This patient education fact sheet accompanies an article that reviews the newer pharmacologic alternatives for ED. Written in question and answer format, the fact sheet discusses ED and its causes, the role of drug treatments, and other non-drug therapies for ED, including vacuum pump devices or surgery. Readers are reminded that ED does not have to be a part of aging, even though there are changes in erectile function that accompany aging. Medical problems that can cause ED include diabetes, high blood pressure (hypertension), and atherosclerosis (hardening of the arteries). Drinking too much, smoking too much, and abusing drugs can also cause ED. The NIH Search Utility
The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to atherosclerosis. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information. The following is a representative sample: •

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to atherosclerosis. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with atherosclerosis. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about atherosclerosis. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “atherosclerosis” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received your search results, click on the name of the organization for its description and contact information. The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “atherosclerosis”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format option “Organization Resource Sheet.” Type “atherosclerosis” (or synonyms) into the “For

these words:” box. You should check back periodically with this database since it is updated every three months. The National Organization for Rare Disorders, Inc. The National Organization for Rare Disorders, Inc. has prepared a Web site that provides, at no charge, lists of associations organized by health topic. You can access this database at the following Web site: http://www.rarediseases.org/search/orgsearch.html. Type “atherosclerosis” (or a synonym) into the search box, and click “Submit Query.”

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.26
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.

[NIH] Myocardial Ischemia: A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (coronary arteriosclerosis), to obstruction by a thrombus (coronary thrombosis), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (myocardial infarction). [NIH] Myocardial Reperfusion: Generally, restoration of blood supply to heart tissue which is ischemic due to decrease in normal blood supply. The decrease may result from any source including atherosclerotic obstruction, narrowing of the artery, or surgical clamping. Reperfusion can be induced to treat ischemia. Methods include chemical dissolution of an occluding thrombus, administration of vasodilator drugs, angioplasty, catheterization, and artery bypass graft surgery. However, it is thought that reperfusion can itself further damage the ischemic tissue, causing myocardial reperfusion injury.
