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 osteogenesis imperfecta 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 osteogenesis imperfecta, 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 osteogenesis imperfecta, 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 osteogenesis imperfecta. 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 osteogenesis imperfecta, 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 osteogenesis imperfecta. The Editors

CHAPTER 1. STUDIES ON OSTEOGENESIS IMPERFECTA Overview In this chapter, we will show you how to locate peer-reviewed references and studies on osteogenesis imperfecta.

The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and osteogenesis imperfecta, 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 “osteogenesis imperfecta” (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: •

How Common Is Hearing Impairment in Osteogenesis Imperfecta? Source: Journal of Laryngology and Otology. 115(4): 280-282. April 2001. Contact: Available from Royal Society of Medicine Press Limited. Publications Subscription Department, P.O. Box 9002, London W1A 0ZA, United Kingdom. E-mail: [email protected]. Summary: Hearing impairment has long been recognized as a common feature in osteogenesis imperfecta, a genetic disorder involving defective development of the connective tissue and characterized by brittle and fragile bones. The figures in some publications could be taken to imply that, with increasing age, the proportion of osteogenesis imperfecta patients with hearing impairment approaches 100 percent. This

Osteogenesis Imperfecta

article reports on a study that examined the incidence of hearing loss in a large survey of 1,394 patients with osteogenesis imperfecta. The authors found that the most common age of onset was in the second, third, and fourth decades of life. At the age of 50, approximately 50 percent of the patients had symptoms of hearing impairment; over the next 20 years there was little further increase. Differences were shown between patients with different clinical types of osteogenesis imperfecta as delineated in the Sillence classification; hearing loss was significantly less common in the type IV disease than in the type I disorder. Among the 29 families with osteogenesis imperfecta type IA there were distinct differences in the likelihood of hearing loss. These findings provide insights which will be valuable in giving patients advice on the likelihood of developing hearing loss in the future. 1 figure. 3 tables. 15 references. •

Treatment of Mandibular Cysts Associated with Osteogenesis Imperfecta Source: Journal of Dentistry for Children. 67(1): 64-66. January-February 2000. Contact: Available from American Society of Dentistry for Children. John Hancock Center, 875 North Michigan Avenue, Suite 4040, Chicago, IL 60611-1901. (312) 943-1244. Summary: Osteogenesis imperfecta (OI) belongs to a group of rare hereditary disorders that are characterized by abnormal bone fragility and a variety of associated disorders. Fractures occur mainly in the extremities. Fractures in the head and face are rarely found, however. The appearance of cysts in the mandible (lower jaw) in association with OI is critical, not only because cysts increase the risk of fractures, but because the prolonged regeneration of bones makes treatment more difficult. This article reviews the treatment of mandibular cysts associated with OI. The authors discuss the symptoms and causes of OI, historical classifications and early case reports, and then present the case of a fifteen year old boy with OI presenting with a large radicular cyst in the mandible. The boy reported approximately twenty spontaneous fractures of his extremities in his lifetime, which were treated conservatively. The authors describe his symptoms and treatment used for the cyst. In this case, because of the size and extension of the cyst, and in spite of the questionable healing quality of the bone, it was decided to do a cystostomy and remove tooth 73. The integrity of the mandible was restored and treatment was completed 6 months postoperatively. 5 figure. 9 references.

Recent Findings in Classification of Osteogenesis Imperfecta by Means of Existing Dental Symptoms Source: Journal of Dentistry for Children. 65(5): 306-309. September-October 1998. Contact: Available from American Society of Dentistry for Children. John Hancock Center, 875 North Michigan Avenue, Suite 4040, Chicago, IL 60611-1901. (312) 943-1244. Summary: This article reviews recent findings in the classification of osteogenesis imperfecta (OI) by means of existing dental symptoms. The authors review the classification of osteogenesis, and describe a clinical study conducted on 49 patients and a survey in which 117 OI-affected persons or their parents had participated. Through this data, the authors established the frequency of dental caries, tooth discolorations and abrasions, as well as radiological abnormalities of teeth in cases of OI. Considering the skeletal severity and the dental symptoms, it was shown that, with an average fracture rate of 2.1, the occurrence of dentinogenesis imperfecta was most frequent in 72.7 percent of the cases. However, it was not possible to confirm the assumption that the probability of a dentinogenesis imperfecta occurrence increases with a rise in fracture rate and an increase in affected bones. The most important criteria for designating dentinogenesis imperfecta as a condition was the existence of pathological tooth

discolorations, after all other causes of discoloration were excluded by differential diagnosis. The authors conclude with a call for the standardization of classification systems internationally for OI and dentinogenesis imperfect (DI). 1 figure. 9 tables. 20 references.

Federally Funded Research on Osteogenesis Imperfecta The U.S. Government supports a variety of research studies relating to osteogenesis imperfecta. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to osteogenesis imperfecta. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore osteogenesis imperfecta. The following is typical of the type of information found when searching the CRISP database for osteogenesis imperfecta: •

Principal Investigator & Institution: Raggio, Cathleen L.; Associate Professor; Hospital for Special Surgery 535 E 70Th St New York, Ny 10021 Timing: Fiscal Year 2002; Project Start 01-SEP-2000; Project End 31-AUG-2003 Summary: (Taken from the application): Recent clinical reports of apparent successful bisphosphonate therapy in children with osteogenesis imperfecta (OI) appear very promising. Previously, we demonstrated that the bisphosphonate, alendronate significantly, reduces fracture incidence and increase density in the growing oirn/oim mouse, an animal model of moderate-severe OI. However, data from that study also indicated that the quality of the newly formed bone was not optimal, and that reductions in long bone growth, might occur with treatment. However, since OI. is a heterogeneous disease clinically and most patients have unique mutations in collagen I formation, there may be a difference in response to treatment with bisphosphonates both short and long term. The long range goal of our studies is to evaluate bisphosphonate treatment in mouse models which have collagen abnormalities analogous to humans, i.e. ,decreased collagen content, abnormal collagen fibers, abnormal collagen packing. The proposed study will test the hypothesis that in 3 different mouse models of O.I. The first is the oim/oim mouse; the second a transgenic mouse which resembles mild-moderate O.I. The third is the new knock-in mouse (Brtl) which resembles mild O.I. The mice will be treated from age 2-14 weeks with alendronate. Bone quality will be assessed before and after treatment by radiographic 2

analysis of the number of fractures, of bone and tooth density and geometry. Analysis of bone ultra structure and histology, and mechanical testing of whole bones; methodologies that have all been used successfully in our previous studies with oimj/oim mice. Investigation of specific aspects of alendronate treatment will provide information critical to the determination of how to proceed with individualized treatment of infants and children with different types of O.I.

Project Title: ANTI-RESORPTIVES FOR DYSREGULATED BONE REMODELING IN OL Principal Investigator & Institution: Camacho, Nancy P.; Associate Scientist; Hospital for Special Surgery 535 E 70Th St New York, Ny 10021 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 31-JUL-2006 Summary: (provided by applicant): It is well established that patients with the collagenbased disease osteogenesis imperfecta (OI) have increased bone turnover (increased degradation and reduced formation). Accordingly, the reports of successful therapy in children with OI with the anti-resorptive agents bisphosphonates are quite exciting, but not unexpected. Despite this apparent success, there are still concerns surrounding the use of anti-resorptive agents in children and in women of childbearing age. Namely, the persistence of the drug in bone tissue over time could have unforeseen consequences, such as adverse effects on fetal development. In addition, it is not known if fracture healing, a biological process that requires extensive resorptive activity, would be compromised in patients treated with bisphosphonates. Further insight into the precise molecular and cellular mechanisms by which bone turnover is increased in OI could lead to more specific targeting of drugs, such that benefits similar to those achieved with bisphosphonate therapy could be realized without potential adverse effects. An exciting potential new therapy would be the use of osteoprotegerin (OPG), a naturally occurring soluble factor synthesized by osteoblasts, which blocks binding of Receptor Activator of NF-kB Ligand (RANKL) to osteoclast precursors and thereby inhibits osteoclastogenesis. The goals of this proposal are to: 1) use the growing oim1dim mouse, an established animal model of moderate-to-severe OI, to determine if treatment with OPG will result in improved bone properties and reduced fracture rate without compromised fracture healing. 2) determine if osteoclasts in the oimloim mice exhibit increased resorptive activity as a result of inappropriate signaling from RANKL produced by osteoblasts, or inappropriate signaling from the presence of abnormal bone mineral, and 3) determine if osteoclasts from patients with OI exhibit similar defective resorptive activity. The specific aims of this proposal are: 1) To treat growing oim1dim mice with OPG for 3 or 6 months, and evaluate specific bone properties, including fracture number, density, geometry, mechanical strength, mineral quality and histomorphometric parameters. Fracture healing will also be evaluated by creation of a closed transverse femoral fracture in the oim1bim mice after OPG treatment. 2) To culture osteoclast precursor cells derived from oim1bim bone marrow cells on bovine bone slices either with RANKIL or with oimldim osteoblasts, and evaluate resorptive activity; To culture osteoclast precursor cells derived from oim1bim bone marrow cells with RANKIL on bone substrates prepared from either oim/bim or +/+ calvarial bone and quantitate resorptive activity. 3) To culture osteoclast precursors from human OI peripheral blood monocytes and similarly evaluate their resoprtive active. The information gained from these studies will permit design of improved therapeutic protocols so that new modalities of treatment for children and adults with OI could be developed.

Project Title: BIOMECHANICAL SIGNALS AND CARDIAC REMODELING Principal Investigator & Institution: Mcculloch, Andrew D.; Professor; University of California San Diego 9500 Gilman Dr, Dept. 0934 La Jolla, Ca 920930934 Timing: Fiscal Year 2002; Project Start 25-AUG-2002; Project End 31-JUL-2007 Summary: (provided by applicant): The overall goal of this proposal is to examine the role that the cardiac extracellular matrix (ECM) plays in the growth and remodeling of ventricular myocardium, both by its contribution to the mechanics of the ventricular wall and by mediating mechanotransduction via cell-matrix interactions. In preliminary studies, ECM mutations in vivo led to significant perturbations of ventricular development in the osteogenesis imperfecta murine (oim) and significantly impaired post-infarction remodeling in the decorin-null (DKO) mouse. In vitro studies implicate integrins as stretch transducers in isolated cardiac cells. There are three specific aims: (1) to investigate how deficiency of type I collagen in the ECM alters myocardial mechanics and leads to developmental adaptations in myocardial structure, time courses of left ventricular (LV) residual strain, myofiber geometry, and orientation will be measured in relation to the postnatal development of collagen matrix and myocardial stiffness in oim and wildtype littermates. A novel in vitro assay using neonatal cardiac myocytes cultured on elastic membranes patterned with collagen microchannels will be used to test the hypothesis that mechanical strain can regulate postnatal myofiber alignment. (2) DKO mice will be used to test the hypothesis that deletion of this small proteoglycan dysregulates post-infarction scar structure, mechanics and ventricular remodeling. Transmission electron microscopy shows abnormalities of microfibril organization in scar collagen of DKO mice. Therefore, mechanical properties will be measured in scars of DKO mice and wildtype littermates 2-8 weeks post-infarction. Microstructural models will be used to investigate the structural basis of altered scar mechanical properties. DKO and WT mice will be followed 4-6 months post-infarction to confirm the hypothesis that dysregulated scar structure accelerates the transition to congestive heart failure, as strongly suggested by preliminary observations. (3) Preliminary studies used novel techniques to micropattern aligned neonatal ventricular myocyte (NVM) cultures and subject them to anisotropic biaxial stretch. Micropatterned myocytes stretched transverse to the myofiber axis exhibited a significant hypertrophic response compared with those in which principal stretch was applied parallel to the myofibrils. By growing cells on different extracellular matrices, function-blocking antibodies and peptides will be used to determine whether these differential responses to anisotropic strain patterns are mediated via specific cell-matrix interactions while carefully controlling for cell shape, cell-cell contact and cell-matrix adhesion.

Project Title: BIOMOLECULAR MECHANICS OF COLLAGEN MONOMERS AND FIBRILS Principal Investigator & Institution: Phillips, Charlotte L.; Associate Professor; Biochemistry; University of Missouri Columbia 310 Jesse Hall Columbia, Mo 65211 Timing: Fiscal Year 2002; Project Start 08-MAR-2002; Project End 28-FEB-2003 Summary: (provided by applicant): Biomechanical stability and strength of connective tissues have long been attributed to covalent intermolecular crosslinks between collagen monomers. Type I collagen, a major component of bone, tendon, skin, and the vasculature, is normally heterotrimeric, consisting of two al (I) chains and a single a2(I) chain, [al(I)2a2(I)]. However, type I collagen in oim mice is exclusively composed of al(I) homotrimers, [al(I)3] (result of a null mutation in the a2(I) gene). Oim mice are a superb

8


model system for examining the functional necessity of the a2(I) chain. We hypothesize that the absence of a2(I) chains perturbs collagen fibril formation, collagen-collagen interactions, and intra- and inter-molecular crosslinking, compromising the structural and biomechanical integrity of connective tissues. In vivo studies using oim mice demonstrate that the presence of type I collagen homotrimers significantly decreases the biomechanical integrity of bone, tendon, skin and aorta. Further analyses using oim mice suggest non-covalent collagen intra- and intermolecular interactions and organization maybe the critical factors regulating mechanical integrity rather than collagen crosslinking. These results question the dogma that covalent intermolecular crosslinks between collagen monomers are the principal determinants of stability and biomechanical integrity of the fibrillar architecture, and compel us to consider other forces and interactions, such as the inherent mechanical properties of individual collagen monomers and non-covalent protein-protein interactions. Recent advances in the application of atomic force microscopy now make it possible to analyze inherent mechanical properties of single biomolecules and molecule-molecule interactions. We propose to use atomic force microscopy to define the role of a2(I) chains 1) in the inherent mechanical integrity of collagen monomers, 2) in non-covalent collagencollagen interactions, and 3) in the inherent mechanical integrity of collagen fibrils, as well as provide a powerful new tool for defining and understanding the pathogenesis of fibrillar collagen mutations and other extracellular matrix components and their role in connective tissue disease.

Project Title: BONE REPAIR BY ALLOGENIC MSC IN NON-ABLATED ANIMAL Principal Investigator & Institution: Lou, Jueren; Orthopaedic Surgery; Washington University Lindell and Skinker Blvd St. Louis, Mo 63130 Timing: Fiscal Year 2002; Project Start 01-JUL-2002; Project End 30-JUN-2005 Summary: (provided by applicant): There are more than one million orthopaedic operations performed each year in the United States, which require bone healing and repair. Developing a new, effective method to enhance bone healing and repair may directly impact clinical outcomes. Such a method can avoid invasive procedures for harvesting bone graft and can also address other problems of bone grafting, such as failure of complete resorption of the grafted bone, difficulty in shaping the bone graft to completely fill the defect, and lack of sufficient bone graft substance for large and extensive bone defects in the clinic. Previous studies showed that implantation of autologous bone marrow derived mesenchymal stem cells (MSC) generates bone formation in vivo. We further demonstrated that bone morphogenetic protein-2 (BMP-2) gene transfer in MSC enhances bone formation compared to autologous implantation of MSC alone. Recent evidence demonstrated that allogeneic bone marrow transplantation into children with severe osteogenesis imperfecta enhances bone formation, which resulted from engraftment of allogeneic MSC and that implantation of allogeneic marrow soaked porous hydroxyapatite ceramics leads to histological bone formation in rats. Thus, we hypothesize that in conjunction with the short term administration of the immunosuppressant, BMP-2 gene transferred allogeneic MSC can survive for a period of time following implantation into bone defect sites of non-ablated recipients. These MSC can overexpress BMP-2 protein for a period of time in situ, which induces both implanted allogeneic MSC and host mesenchymal progenitor cells to express bone matrixes and to form bone. Our aims are:1. To investigate the repair of femur defects in non-ablated rats with BMP-2 gene transferred allogeneic MSC for repair.2. To investigate the fate of implanted allogeneic MSC in femur defect site of non-ablated rats.

Project Title: CHEMISTRY AND BIOLOGY OF COLLAGEN Principal Investigator & Institution: Raines, Ronald T.; Professor; Biochemistry; University of Wisconsin Madison 750 University Ave Madison, Wi 53706 Timing: Fiscal Year 2004; Project Start 15-JUL-1996; Project End 31-MAR-2008 Summary: (provided by applicant): Collagen comprises one-third of the protein in humans. Collagen abnormalities are associated with a wide variety of human diseases, such as osteogenesis imperfecta, Ehlers-Danlos syndrome, and some types of osteoporosis and arthritis. The long-term objective of the proposed research is to reveal in atomic detail the chemical basis for the unique triple-helical structure of collagen, and the roles of collagen in human health and disease. Specific Aims: (1) Basis for Triple Helix Stability. The hypothesis to be evaluated is that individual strands of collagen are preorganized to form a triple helix. The experiments make use of collagen strands containing nonnatural amino acids (in particular, 4-fluoroproline diastereomers and Nmethylglycine) that impose distinct stereoelectronic and steric effects. Data on conformational stability will be reinforced by computational and structural analyses. (2) Cystine Knot Templates. A collagen triple helix cross-linked by two disulfide bonds (that is, a cystine knot) can contain three different strands, and provides a realistic mimic of natural collagen. An efficient solid-phase synthesis of triple helices crosslinked by a cystine knot will be developed, and those helices will be used to evaluate the contribution of the ladder of interstrand main-chain-main-chain hydrogen bonds to collagen stability, assess the ability of a single strand of collagen to invade a triple helix, and self-assemble long, well-defined triple helices. (3) Encoded Collagen Library. Phage display of a cystine knot will be used to generate encoded libraries of collagen triple helices. These libraries will be screened for triple helices with high affinity for collagenbinding proteins, in particular, the adhesin protein from the pathogenic bacterium Staphyloccocus aureus. Significance: The results of the proposed research will provide new insights into the structure and conformational stability of the collagen triple helix and on its interaction with other proteins, and could ultimatley lead to the creation of collagen mimics and collagen-based biomaterials with important therapeutic applications.

Project Title: COLLAGEN GENE TARGETING WITH AAV VECTORS Principal Investigator & Institution: Russell, David W.; Assistant Professor; Medicine; University of Washington Grant & Contract Services Seattle, Wa 98105 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 31-JUL-2006 Summary: (provided by applicant): Collagen Gene Targeting with Adeno-Associated Virus Vectors Osteogenesis Imperfecta (OI) is a genetic disease caused by mutations in the type I collagen genes COLIAI or COL1 42 that can result in major skeletal abnormalities, deformities, frequent fractures, pain, and premature death. Severe forms of OI are typically caused by dominant mutations that disrupt the Collagen triple helix, so an effective treatment will require removal or correction of dominant, mutant alleles. The long-term objective of this proposal is to develop a novel approach for the treatment of OI based on the transplantation of genetically modified autologous mesenchymal stem cells (MSCs) that are expected to produce bone-forming osteoblasts in vivo.

Adenoassociated virus (AAV) vectors have been shown to efficiently introduce specific genetic modifications into homologous chromosomal sequences, and here they will be used both to knockout and correct mutant, human COL 1A I alleles. Experiments will be performed with an existing collection of OI fibroblasts with defined COLIA1 mutations, and with an OI MSC bank established and characterized here. In one strategy, a single AAV targeting vector will be used to knockout any COL 1A allele, with the goal of converting severe OI due to helix-disrupting mutations to a mild form of OI due to a single null allele. In other strategies, AAV targeting vectors will be designed to correct specific COL 1A1 mutations and create wild-type alleles. Several approaches will be developed to select for cells that have undergone AAV-mediated gene targeting and express normal COL1 1A genes, with the goal of simplifying the ex vivo manipulations that would be used in future clinical trials. The proliferative and muItilineage potential of gene-targeted MSCs will be assessed by in vitro assays and also by an in vivo boneforniing assay after implantation in immunodeficient mice. Mixtures of MSCs marked with reporter genes will be assayed together to assess proliferation and bone formation when MSCs with different COLIA] genotypes coexist. In order to promote the engraftment of genetically modified MSCs, we will use chemical inducers of dimerization to multimerize engineered growth factor receptors and provide an inducible cell proliferation switch to MSCs. This switch will provide a method for pharmacologically controlled in vivo expansion of MSCs after transplantation. These studies are intended to lay the groundwork for future clinical trials for OI and other diseases that could benefit from the transnlantation of autologous genetically modified MSCs.

Project Title: COLLAGEN-PROTEOGLYCAN INTERACTION IN CONNECTIVE TISSUE Principal Investigator & Institution: San Antonio, James D.; Assistant Professor of Medicine; Medicine; Thomas Jefferson University Office of Research Administration Philadelphia, Pa 191075587 Timing: Fiscal Year 2002; Project Start 20-SEP-2002; Project End 31-AUG-2005 Summary: (provided by applicant): Over 300 mutations in type I collagen are associated with heritable connective tissue (CT) disorders in humans, characterized by altered matrix assembly, stability, and function. Proteoglscans', (PGs) including decorin, keratocan and lumican reside on type I collagen fibrils in various tissues, and are proposed to regulate fibril assembly and lateral association. We propose that such PGtype I collagen interactions are key regulators of matrix structure in healthy tissues, and that their disruption may be the underlying mechanism of certain CT diseases. We specifically mapped the spatial relationships between ligand-binding sites and mutation positions on type I collagen (DiLullo et al., 2002, J. Biol. Chem, 277, 4223), and reported that PGs may impact upon a number of type I collagen functions. Despite this, their sites of interaction remain poorly defined. Moreover, our map revealed that some mutations for osteogenesis imperfecta and other diseases co-localize with putative PG-binding sites, as do triple helical regions that lack reported mutations, further implicating PGcollagen interactions as key regulators of matrix structure. Thus, to better define the contribution of collagen-PG interactions to healthy tissues and to CT diseases, we will: 1) Synthesize type I collagen mimetic triple helical peptides (THPs) carrying candidate PG-binding sequences, and use them to construct a collagen peptide microarray; 2) Purify type I collagen-binding PGs and screen for their binding sites in type I collagen through use of the peptide microarray, and by affinity coelectrophoresis; and 3)

This work will: 1) increase our understanding of the role of PGs in type I collagen assembly, function, and in human diseases, 2) explore the feasibility of collagen peptide microarrays for the functional screening of collagen-intcractive ligands, and 3) lead the way to developing transgenic models for probing the in vivo function of PG-type I collagen interactions.

Project Title: CORE--INFRARED IMAGING Principal Investigator & Institution: Paschalis, Eleftherious P.; Hospital for Special Surgery New York, Ny 10021 Timing: Fiscal Year 2002 Summary: The biomedical research base and the pilot and feasibility projects in the proposed Core Center all require mineral analysis at high spatial resolution. Fourier transform infrared spectroscopy is well suited for the study of both hard and soft tissues. It provides information on all tissue compartments, including mineral, mineral substituting carbonate, collagen, non-collagenous proteins, lipids, and proteoglycans. The Infrared (IR) Imaging Core will provide standard FTIR analyses along with infrared images acquired using a newly developed methodology. The recent availability of an IR array detector that can acquire 4096x4096 pixels of data at 7 m resolution offers the potential for data acquisition at 1000 times that of the conventional IR microscope at a much higher spatial resolution. In order to increase the efficiency of data acquisition on projects that already are using FTIR Microspectroscopy and to develop and validate new parameters which previously could not be obtained without the array detector, the IR Imaging Core requests funds to establish the core around the newly acquired FTS 6000 Stingray Infrared Microimaging System. On-going studies that will benefit from this instrumentation address specific questions about mineralized and non-mineralized connective tissues important to the study of bone development. These include how lipid phases change in the stratum corneum, how altered expression of non- collagenous matrix proteins affect bone mineral content and mineral properties, which is the effect of similar modification on the mineral and matrix formed in chondrocyte cultures, how does IL-6 affect bone mineral properties in vitro and in vivo, what are the mineral and matrix characteristics around loaded and unleaded osteocytes, how does the mineral changes as microdamage propagates, how does osteoarthritis alter bone mineral and matrix properties in a mouse model, what is the origin of bone fragility in osteogenesis imperfecta, and what are the changes in mineral and matrix that occur in osteoporosis and are they corrected by treatment with various therapeutic modalities.

Project Title: DEVELOPMENT OF A TREATMENT FOR OSTEOGENESIS IMPERFECTA Principal Investigator & Institution: Martin, R. Bruce.; Professor and Director; Orthopaedic Surgery; University of California Davis Sponsored Programs, 118 Everson Hall Davis, Ca 95616 Timing: Fiscal Year 2002; Project Start 15-JUL-2000; Project End 30-JUN-2004 Summary: The goal of this study is to use an animal model to test a method for treating a class of bone diseases known as osteogenesis imperfecta (OI). In these disorders, the patient has one of numerous possible mutations in the genes that code for Type l collagen. This results in the production of abnormal Type l collagen molecules, or

12


insufficient amounts of this structural protein, or both. In any case, there can be substantial weakening of the patient's bone tissue. This leads to fractures caused by (1) the weakened bone material, and (2) excessive porosity produced by the bone's attempt to repair itself by remodeling. OI patients can only be cured through correction of their genome, a prospect on the horizon but unlikely to affect many patients soon. In the meantime, we propose that substantial amelioration of this disease can be achieved in children by controlling the bone modeling and remodeling processes so as to compensate for, and restrain negative responses to, the collagen defect. The agent we propose to use for this purpose is alendronate, a bisphosphonate that blocks bone resorption. This drug could benefit the juvenile OI patients by blocking the normal resorptive process on the metaphyseal surfaces of the patient's long bones, resulting in larger bones that compensate for the weak material within the cortex. Unfortunately, however, it is also possible that alendronate could interfere with the growth of the patient and produce negative as well as positive effects in terms of skeletal development. The specific aims are to 1) use the oim transgenic mouse model to test this method of treatment and elucidate its mechanisms in detail, and 2) determine whether the use of alendronate in children will have negative effects of their growth.

Project Title: IDENTIFICATION OF OSTEOGENIC PROGENITOR CELLS IN SKELET* Principal Investigator & Institution: Goldhamer, David J.; Associate Professor; Molecular and Cell Biology; University of Connecticut Storrs Unit 1133 StorrsMansfield, Ct 06269 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 31-JUL-2006 Summary: (provided by applicant): Cell-based therapies are emerging as a potentially powerful treatment for osteogenesis imperfecta, a genetic skeletal disorder characterized by bone fragility and deformities caused by defects in type I collagen. 0steogenic progenitor cells of possible therapeutic utility exist in skeletal muscle tissue, although their identity is unknown. In the present proposal, in vivo bone induction assays in mice will be used in conjunction with Cre/lox lineage tracing to definitively establish the osteogenic potential of five candidate cell types resident in skeletal muscle tissue: quiescent and activated muscle satellite cells, vascular smooth muscle (VSM) cells, pericytes and endothelial cells. Each cell type will be specifically and permanently labeled with lacZ by intercrossing two mouse strains: transgenic mice that express the gene for Cre recombinase under the control of a cell type-specific promoter/enhancer (MyoD-cre for satellite cells, smooth muscle myosin heavy chain-cre for VSM and pericytes, and Tie2-cre for endothelium) and Rosa26 Cre reporter mice, in which LacZ expression is Cre-dependent. The osteogenic potential of these cell types will be determined by following their fate after intramuscular injection of purified bone morphogenetic protein 2, which induces a robust osteogenic response that recapitulates normal endochondral bone formation. Cellular contributions to cartilage and bone will be determined by 0-galactosidase histochernistry and immunohistochemistry using cellspecific markers. In addition, the genetic control of satellite cell commitment and osteoinduction will be explored by assessing the osteogenic potential of satellite cells in mice carrying a null mutation in the muscle regulatory gene, MyoD. Finally, the osteogenic potential of muscle side population (SP) stem cells-recently identified by FACS analysis-will be evaluated in cell culture, and their relationship to satellite cells, VSM, pericytes and endothelium will be determined by combining lineage marking with FACS analysis of muscle-derived cells. Establishing the identity of osteogenic

progenitor cells of skeletal muscle will provide the foundation for investigating mechanisms regulating commitment to the osteogenic lineage. Evaluating these osteoprogenitor cells in future cell transplantation models will provide an essential preclinical test of their utility for the treatment of osteogenesis imperfecta and other diseases of the musculoskeletal system.

Project Title: MARROW STROMAL CELLS FOR LYSOSOMAL DISEASE CNS DEFECTS Principal Investigator & Institution: Phinney, Donald G.; Assistant Professor; Center for Gene Therapy; Tulane University of Louisiana New Orleans, La New Orleans, La 70112 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 31-AUG-2005 Summary: (provided by applicant): Resident in adult bone marrow is a cell population referred to as marrow stromal cells (MSCs) that possess several unique properties. First, MSCs mediate various aspects of hematopoiesis by expressing matrix molecules, cytokines and cell-surface receptors that provide architecture to the hematopoietic organ, support granulopoiesis and lymphopoiesis, and maintain the multi-potency of the hematopoietic stem cell. Second, MSCs are also able to differentiate into a variety of mesenchymal cell lineages, including osteoblasts and chondrocytes, suggesting the cells participate in most aspects of bone growth and repair. Accordingly, the potential of MSCs as cell and/or gene therapy vectors for the treatment of connective tissue diseases is being intensively studied. Such efforts have culminated in the first human clinical trial using MSCs to treat Osteogenesis Imperfecta. While the relevance of using MSCs to treat connective tissue diseases is obvious, our recent data regarding intracranial transplantation of MSCs suggests the cells may be useful vectors to treat central nervous system (CNS) disorders, as well. We recently showed that following injection into neonatal mouse brains, murine MSCs undergo marked expansion, migrate along established white matter tracts throughout successive layers of the brain, and at a low frequency adopt glial and possibly neuronal cell fates. Therefore, MSCs respond to the microenvironment of the developing brain in a manner similar to neural progenitor cells. To explore this potential of MSCs further, we propose to compare and contrast the engraftment, proliferation, migration, and differentiation of MSCs following injection into embryonic, neonatal, or adult brain with particular emphasis on 1) quantitating the number of MSCs that persist in brain as a function of time, 2) mapping their anatomical locations, and 3) characterizing their phenotype. By analyzing how brain development affects MSC engraftment, we can optimize a transplantation regimen that translates into an effective clinical strategy for using MSCs to treat CNS disorders. To directly assess the therapeutic potential of MSCs, we will transplant the cells into the brains of mice afflicted with Mucopolysaccharidosis Type VII, which exhibit progressive CNS neurodegeneration. These experiments will be conducted in a maimer so that they provide a basis for using a patients own MSCs to treat disorders affecting the CNS.

Project Title: MARROW STROMAL CELLS IN OSTEOGENESIS IMPERFECTA MODEL Principal Investigator & Institution: Pochampally, Radhika R.; Medicine; Tulane University of Louisiana New Orleans, La New Orleans, La 70112 Timing: Fiscal Year 2002; Project Start 05-AUG-2002

Summary: (provided by applicant): Osteogenesis Imperfecta (OI) that has an incidence of 1/10,000 - 1/20,000 live births, has frequently served as a model disorder for dominant negative conditions of structural proteins. Effective therapy for these disorders will require direct or targeted replacement of a mutated gene with wild-type allele. This research proposal will explore the possibility that patients with OI can potentially be treated with their own osteoprogenitors by gene-engineering the cells from their bone marrow that are referred to as mesenchymal stem cells or marrow stromal cells (MSCs). The marrow stromal cells will be used to test the hypothesis that marrow stromal cells from the patients with OI can be gene-engineered to correct the deleterious effects of mutations in type I collagen that produce the disease. The Specific Aims for this proposal are: (1) To obtain homologous recombination of the COL1A1 gene in human MSCs to determine the possibility of alleviating the OI symptoms by replacing the mutant allele with wild type allele of COL1A1 (2) To obtain overexpression clones of hMSCs that express COL1A1 cDNA to determine the effect of ratio of wild-type to mutant COL1A1 protein (3) To study the repair potential and homing of gene engineered hMSCs; the repair potential of gene engineered MSCs will be determined by injecting the cells into the fracture model and control mice.

Project Title: MECHANICAL ENVIRONMENT IN MANDIBULAR DISTRACTION Principal Investigator & Institution: Herring, Susan W.; Professor & Acting Chair; Orthodontics; University of Washington Grant & Contract Services Seattle, Wa 98105 Timing: Fiscal Year 2002; Project Start 01-JAN-2002; Project End 31-DEC-2006 Summary: (provided by applicant): Distraction osteogenesis (DO) is a means to elongate bone by placing tensile loads on a healing osteotomy. Although DO has been used on the mandible for only a decade, the technique is already supplanting more traditional orthognathic procedures, especially for children. Despite the fact that DO uses mechanics to accomplish its goals, the actual mechanical environment is unknown. Functions such as mastication must place intermittent compressive or shearing strains on the distraction site. These strains, as well as the tensile strains produced by the distraction appliance, are of critical biological significance for the osteogenic process, but have never been measured. Using a well-established model for mandibular DO, the pig, we propose (Aim 1) to clarify the mechanical environment of the distraction site at the time of osteotomy, during distraction, and during consolidation by making direct measurements of strain using strain gages, digital ultrasonics and differential variable reluctance transducers. These studies will investigate the influence of appliance size, stability, and placement as well as the action of specific muscles and occlusal loads. Further, we will address a major concern of treating growing children by mandibular DO, whether the procedure adversely affects growth at the mandibular condylar by overloading the TMJ. Thus, we propose (Aim 2) to ascertain the impact of DO on TMJ mechanics and growth by performing strain gage measurements on the condylar neck and relating the findings to growth, as measured by mineral apposition rate and periosteal deformation. The mechanical environment of DO, particularly the stability of the distraction site, may affect the course of healing and the final result by influencing which cells are recruited, the rapidity with which they proliferate, and their eventual fate. Therefore, we propose (Aim 3) to relate the mechanical history of DO to the repair process by assessing the contributions of the periosteum, muscle connective tissue, and vascular system to the regenerate. This will be accomplished by pulse labeling of replicating cells during distraction, combined with an investigation of protein expression at the time of sacrifice. The most important contributions of this proposal

will be the characterization of strain at the DO site under natural conditions, and the application of that information to understanding of how DO works on a cellular level and how it affects mandibular growth. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

It will be used as a supplement for the General Clinical Research Center (GCRC) at the Indiana University School of Medicine. The broad objective is to provide a five-year period of mentored support for Dr. DiMeglio to facilitate her development as an independent clinical investigator. The application includes both a systematic career development plan and a clinical research project. The career development plan includes: l) completion of the Indiana University GCRC Department of Medicine two year Clinical Investigator Training Enhancement Program, 2) completion of a Master's Degree Ln Public Health, and 3) careful mentorship by Munro Peacock, MD, Ora Pescovitz, MD, and other researcher physicians to foster Dr. DiMeglio's evolution into a productive and independent clinical research investigator. The clinical research proposal describes a study to evaluate the efficacy and safety of "Bisphosphonate Therapy for Osteogenesis Imperfecta (OI)." OI is a heritable disorder of collagen synthesis. Affected persons have low bone mineral density and experience multiple fractures and progressive bony deformity. In its most severe form, the disorder is lethal in infancy. To date, no effective therapy exists for this debilitating condition. Improyements in bone mineral density and in fracture rates in a small number of children treated with intravenous bisphosphonates have been reported. The efficacy of oral bisphosphonates has not been established. We will characterize the changes effected by oral bisphosphonate therapy and compare them to a regimen of intravenous bisphosphonate therapy in a group of children with OI.

Advancements in the structural basis of disease and the design of novel biomaterials will be obtained using computational

16


methods and principles from the above mentioned sciences. Inclusion of the analysis of sequence information (bioinformatics) allows for more direct studies at a molecular level of large biopolymers and fibril proteins such as collagen. The long-term goal of this proposal is to determine the structural, physical and energetic properties of biopolymers using computational chemistry methods including thermodynamic integration and molecular dynamics. An increased understanding of the underlying molecular structure of native and mutant collagen molecules will elucidate the abnormal behavior of altered collagen molecules. This proposal defines a computational approach for determining the major forces contributing to the stability of collagen. This information will provide a foundation for constructing an energetic-structural map of the triple-helical domain for collagen. This map will ultimately be used as a basis for a computational genetic screening protocol to predict the phenotype of Osteogenesis Imperfecta (OI), serve as the foundation for understanding other fibril collagenous genetic disorders, and provide the detailed molecular information required for the design of novel collagen-like biomaterials. The specific aims of this proposal are: (1) determine the major forces contributing to the stability of the collagen triple-helix by simulating the structural and energetic effects on homotrimer collagen-like peptides; (2) determine the disruption effects of helix registration for known mutations associated with Ehlers-Danlos Syndrome (EDS) by simulating the structural and energetic effects that a glycine substitution has on disulfide bridge formation in the homotrimer type III collagen fragments; (3) determine the energetic and structural effects of different substituents on a naturally occurring sequence and four glycine mutants for a type I collagen fragment; (4) determine the neighborhood effects and individual contributions of electrostatics including hydrogen bonds and conformational changes for the OI regional phenotype model; and (5) determine the correlation among the computed thermodynamic quantities, experimental and clinical data associated with a particular mutation in the triple helix.

Project Title: NIH OSTEOPOROSIS & RELATED BONE DISEASES RESOURCE CENTER Principal Investigator & Institution: Dawson-Hughes, Bess V.; Professor of Medicine; National Osteoporosis Foundation 1232 22Nd St Nw Washington, Dc 20037 Timing: Fiscal Year 2002; Project Start 30-SEP-1998; Project End 31-AUG-2003 Summary: (Taken from the Application) In 1993, Congress issued a mandate to increase awareness and knowledge about osteoporosis and related bone diseases. In response, the leading national nonprofit organizations in the field, the National Osteoporosis Foundation (NOF), The Paget Foundation (PF), and the Osteogenesis Imperfecta Foundation (OIF), were selected to establish the first national resource center in the field. In 1997, with 28 million Americans diagnosed or at risk for osteoporosis, 1.5 million painful fractures, $14 billion in health care costs, and millions affected by Paget's disease, osteogenesis imperfecta, and other related bone diseases, Congress renewed the Center's mandate. NOF and its collaborating partners propose to broaden and expand the reach of the current NIH Osteoporosis and Related Bone Diseases National Resource Center. Aim 1 focuses on strengthening the Center's infrastructure and broadening its services. Under the guidance of an Advisory Council, specific tasks include expanding the acquisition of research information and inquiry services; promoting the Center to physician and public audiences through exhibits, public service announcements and other means; and widely disseminating information via Web sites and other electronic methods, a speaker's bureau, and print publications such as

bibliographies, fact sheets, and an expanded newsletter, to medical professionals, managed care organizations, and underserved and at-risk populations, including youth, men, and Hispanic and Asian American women. Aim 2 focuses on developing partnerships to create and evaluate a model education program to enhance bone health and reduce future risk of osteoporosis among a key group---adolescent females. The program will be based on a Center-sponsored communications study of the delivery of health promotion messages to this audience. Aim 3 is intended to expand awareness and use of research data. Specific efforts include supporting the National Osteoporosis Data Group, collecting and disseminating definitive statistics on bone diseases and on conditions co-morbid with osteoporosis, and preparing summary reports.

Project Title: OSTEOPROGENITORS FOR POTENTIAL THERAPY OF OI Principal Investigator & Institution: Prockop, Darwin J.; Professor; Center for Gene Therapy; Tulane University of Louisiana New Orleans, La New Orleans, La 70112 Timing: Fiscal Year 2002; Project Start 21-SEP-2001; Project End 31-JUL-2006 Summary: (provided by applicant): This proposal will explore the possibility that patients with osteogenesis imperfecta (OI) can potentially be treated with their own osteoprogenitors by gene-engineening the cells from their bone marrow that are referred to as mesenchymal stem cells or marrow stromal cells (MSCs). We will use antibodies to surface epitopes we have recently identified to prepare clonal and homogeneous preparations of the earliest progenitors in cultures of MSCs that have an enhanced ability to undergo multilineage differentiation and that are rapidly self-renewing cells (RS cells). The RS cells will be used to test the hypothesis that they are similar to CD34 positive stem cells used for bone marrow transplants and that therefore they will be the most effective cells to provide long-term engraftment of osteoprogenitors into bone. We will also test the hypothesis that RS cells from patients with OI can be gene-engineered to correct the deleterious effect, of mutations in type I Collagen that produce the disease. The Specific Aims are (1) Use a series of antibodies to surface epitopes we have recently identified to prepare clonal and homogeneous preparation, of RS cells from cultures of human MSCs. In the process, test the hypothesis that RS cells can be further fractionated to obtain homogeneous preparations of stem cells that are even more effective as osteoprogenitors for engrafment into bone. (2) Define the osteogenic potential in vitro of the RS cell preparations by assays of the rates of mineralization and assays of expressed genes by mRNA microarrays and proteomics. (3) Determine the osteogenic potential in vivo of the RS cell preparations by assays of differentiation into bone after subcutaneous implantation in vehicles or after systemic infusion into immunodeficient mice. (4) Determine the feasibility of correcting the gene defect in a patients own RS cells, (a) by overexpression of a cDNA for the wildtype COL I A I gene, or (b) by replacing a mutated COLlAl gene by homologous recombination.

The principal outcome measures to be assessed will be: 1) lumber spine and femoral neck bone mineral content and bone mineral density. 2) fracture rate and pain. 3) biochemical parameters of bone formation/resorption. 4) bone histomorphometry. 5) disability evaluation. 6) evidence of restoration of vertebral morphometry.

Project Title: QUANTITATIVE MICROTOMOGRAPHY OF BONE TRABECULAE Principal Investigator & Institution: Flynn, Michael J.; Bioscience Professor; Radiation Oncology; Case Western Reserve Univ-Henry Ford Hsc Research Administraion Cfp046 Detroit, Mi 48202 Timing: Fiscal Year 2002; Project Start 25-SEP-2001; Project End 31-AUG-2004 Summary: (provided by applicant): X-ray computed tomography of the spine and hip is an established method for quantitative bone mineral measurement that resolves elements with 1-millimeter size. For bone specimens, high-resolution laboratory computed tomography systems can describe cancellous bone architecture with resolved elements of about 50 micrometers. This is sufficient to describe bone volume, trabecular thickness and orientation, and connectivity. We have recently developed a new innovative method to perform quantitative computed tomography on an individual bone trabecula with resolved elements of 1 micrometer. Whole trabeculae are separated from cancellous bone specimens and scanned in a 250 micrometer diameter saline filled tube. A beam of x-rays from a synchrotron source is focused using a zone plate and used to make numerous measurements of radiation transmission. The measured data is then reconstructed to a 600 x 600 x 540 array of values having a spacing of 1/3 micrometers in the X, Y, and Z direction. High speed scanning devices will be used on this project to enable examination of 16 specimens per day. This method should be extremely valuable for evaluating the microscopic properties of bone tissue with respect to the mineralization of the matrix and porosity associated with osteocyte lacunae. To establish this value, four biomedical experiments are proposed for which genetic, pharmacologic, and biomechanic variables will be used to alter the bone tissue in animals. Prior experience indicates that these models should alter the mineralization and porosity at a microscopic scale. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Summary: (provided by applicant): With the intention of identifying novel genes involved in the arterial response to injury we undertook a differential screen of genes expressed in normal and injured arteries. We identified a novel sequence that with the exception of bone was not expressed in normal tissues, but highly induced in injured arteries. This cDNA contained an open reading frame of 245 amino acids with no significant homology to any known protein with the exception of a 36 amino acid (aa) long domain with 59% homology to the helical repeat regions found in collagens. Comparison with the human cDNA revealed 98% identity at the amino acid level indicative of a highly conserved protein. Northern blotting of mRNA derived from various adult rat organs revealed significant levels of this mRNA only in bone and lung. In balloon-injured arteries expression of this mRNA was prominent in adventitial fibroblasts during the proliferative and remodeling phase and only little expression was seen in smooth muscle cells of the developing neointima. Bone showed expression in the matrix of resting, proliferating and hypertrophic chondrocytes but expression was lost from the matrix as chondrocytes reached the apoptotic zone of the growth plate. Expression was also observed in periosteal cells. Based on its expression pattern, we named the gene remodelin. Several findings indicate that remode!in has important biological functions particularly in the arterial response to injury as well as in bone and cartilage matrix formation. These include: 1) increased remodulin expression in vitro is associated with decreased TGF-Beta expression as well as reduced TGF-Beta dependent gene expression (collagens type I and III), 2) increased remodulin expression in vivo results in phenotypes reminiscent of collagen mutants found in osteogenesis imperlecta (01), dystrophic epidermolysis bultosa (DEB) and myopathies (Bethlem), 3) in the absence of remodelin, expression of bone differentiation markers such as osteopontin and alkaline phosphatase (ALP) are dramatically increased, and 4) inhibition of Cbfa1 dependent gene expression such as osteocalcin by remodeiin. As such, remodelin appears to be an in vivo regulator of skeletal tissues and wound healing responses, potentially influencing calcification and differentiation along the chondrocyte/osteoblast lineages. As a potential inhibitor of calcification in the vessel wall this proposal will examine the role of remodelin in vascular calcification and remodeling using both in vitro and in vivo approaches.

Project Title: SECOND HARMONIC GENERATION IMAGING MICROSCOPY Principal Investigator & Institution: Campagnola, Paul J.; Assistant Professor; University of Connecticut Sch of Med/Dnt Bb20, Mc 2806 Farmington, Ct 060302806 Timing: Fiscal Year 2002; Project Start 01-JUN-2002; Project End 31-MAY-2006 Summary: Type I collagen is the most abundant extra-cellular matrix protein being the primary structural component of bone, skin tendon and to a lesser extent blood vessels. Although its biochemical and ultrastructural properties are well understood, there are still gaps in our knowledge the precludes genotype/phenotype predictions in diseases affecting its primary structure or its gene regulation. This proposal will evaluate a new method for visualizing extra-cellular matrix Type I collagen fibers in cell culture or in intact tissues in real time utilizing second harmonic generation (SHG) imaging microscopy. This is a new and novel imaging technique that can be used to probe endogenous structural proteins with high contrast without the need for exogenous labels. Furthermore, this method provides intrinsic 3-dimensionality and is ideal for intact tissues since samples (up to 1 mm) can be imaged in situ. This method provides resolution on the order of 500 nm and is ideal for probing higher-level organization of collagen fibrils and fibers. SHG imaging will allow the direct visualization of some of

20


the physical properties of the collagen triple helices. Studying the organization of collagen fibrillar structure by SHG imaging will in fact complement existing ultrastructural (X-ray diffraction and electron microscopy) and non-imaging (NMR, CD) methods. The value of this approach will be assessed in two disease of type I collagen that are a consequence of either under accumulation (osteogenesis imperfecta, OI) or excessive accumulation (tight skin, Tsk) of type I fibers in bone or skin respectively. In both cases, the relationship between the underlying genetic abnormality and the severity of the disease is not understood and a unique insight into this relationship may come from this method. We will first establish quantitative measurements of the collagen fibers in the ECM of normal murine tissues by SHG where we will utilize both tissue culture cells, and as well as tissues and decalcified bones from wild type mice. This methodology may ultimately become a powerful clinical tool both in terms of predictive value of musculo-skeletal diseases as well as in the assessment of the efficacy of drug and gene therapies.

Project Title: STEM CELL THERAPY FOR DISEASES OF BONE IN A MOUSE MODEL Principal Investigator & Institution: Niyibizi, Christopher; Associate Professor; Orthopaedic Surgery; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2002; Project Start 27-SEP-2002; Project End 31-AUG-2006 Summary: The focus of the present proposal is to utilize a mouse model of osteogenesis imperfecta (oim) as a model system to evaluate the potential of the bone marrow derived mesenchymal stem cells (BMSCs) to engraft and participate in repair and regeneration of bone. The mouse has a natural occurring mutation that results in nonexpression of proa2(I) chains leading to the accumulation of al(I) homotrimers in tissues. The mouse exhibits osteopenia, cortical thinning and easy fracturing and is an excellent model for evaluating the potential of BMSCs as targets for the treatment of genetic and non-genetic diseases of bone. Recent clinical trial by Horwitz et al. using whole marrow in children with a severe form of OI, demonstrated that BMSCs may offer treatment options for O1. Therefore, the hypotheses to be tested are: BMSCs from normal donor mice administered systemically or locally into syngeneic recipient mice will engraft in the bones of the recipient mice, synthesize authentic bone extracellular matrix and contribute to the structural integrity of the host bone. The following specific aims will be used to test these hypotheses: 1) Demonstrate that the cells infused into oim mice will engraft in bone and in fracture sites created in oim mice 2) Demonstrate that the cells which engraft in bone differentiate into osteoblasts and synthesize the authentic bone extracellular matrix and 3) Demonstrate that the cells that engraft in bone contribute to the structural integrity of bone. To accomplish the above aims, BMSCs will be established from femurs and tibiae of normal donor mice and either marked with retroviruses expressing LacZ or GFP genes to aid in cell tracking or unmarked prior to infusion in oim mice. The fate of the infused cells will be tracked by following expression of the marker genes in tissue and by fluorescent in situ hybridization (fish). Differentiation of the transplanted cells into osteoblasts in vivo will be determined by co-localization of osteocalcin and marker genes and also by in situ hybridization. Synthesis of authentic extraceltular matrix by the infused cells will be analyzed by the determination of the presence of type I collagen comprised of 1 and 2 heterotrimers. Structural integrity of the host bone, will be determined by histophotometry, crosslinking, and collagen content and bone mineral density. The proposed studies may lead

Project Title: STRUCTURAL STUDIES OF COLLAGEN FIBRILS BY NMR Principal Investigator & Institution: Wittebort, Richard J.; Professor; Chemistry; University of Louisville University of Louisville Louisville, Ky 40292 Timing: Fiscal Year 2000; Project Start 01-SEP-1992; Project End 31-MAR-2004 Summary: Our overall aim is to apply solid state NMR to oriented collagen fibrils, nature~s most abundant protein and to develop this technique for studying fibrous proteins and other macromolecular structures not amenable to x-ray diffraction or solution NMR methods. We propose to use solid state 2H, 13C and 15N NMR spectroscopy of collagen fibrils to directly determine essential elements of this important protein~s secondary structure. These studies make use of oriented fiber and magic angle spinning (MAS) methods. Structural features to be determined are the average orientation of individual peptide planes of the collagen tripeptide repeat relative to e fiber axis and the location of structural waters. The measurement and interpretation of 13C, 17O and 15N chemical shift parameters will be further developed with regard to a general method for determining secondary structure in solid proteins. Collagen provides the proteinaceous matrix for bone, it is the dominant material in and responsible for the tensile strength of tendons and it maintains the structural integrity of veins and arteries. In more than 90% of the cases of children with the heritable disorder of osteogenesis imperfecta, there is a mutation in the genes for type I procollagen. Clini l symptoms include extreme bone fragility, hypermobility and congenital dislocation of joints, osteoarthritis, osteoporosis and skin abnormalities. The architecture of the supramolecular collagen assembly is particularly sensitive to mutations which disrupt the structure of the collagen molecule anywhere along its 3000 A length, thus the collagen molecular structure is fundamental. We anticipate that these experiments will define the range of conformations that are allowed in the collagen triple helical motif. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: STRUCTURAL STUDIES OF TRIPLE-HELICAL PROTEINS Principal Investigator & Institution: Brodsky, Barbara M.; Professor; Biochemistry; Univ of Med/Dent Nj-R W Johnson Med Sch Robert Wood Johnson Medical Sch Piscataway, Nj 08854 Timing: Fiscal Year 2003; Project Start 01-MAR-1977; Project End 31-AUG-2007 Summary: A peptide approach to a comprehensive understanding of the effect of amino acid sequence (Gly-X-Y)n on the stability, conformation, folding, dynamics and selfassociation of the normal and mutant collagen triple-helix is in progress. Our goals are to complete sequence-stability correlations at the molecular level; to develop peptides to model triple-helix self-association; and to pursue the disruption caused by Gly substitutions found in collagen diseases. Previous host-guest peptide studies established the triple-helix propensities of all 20 amino acids for the X and Y positions, and evaluation of molecular interactions within the triple-helix will be completed. These relationships between Gly-X-Y sequence and stability will be used to formulate predictions for the global stability of collagen model peptides and to relate local stability variations along collagen with ligand binding sites, microunfolding implicated in fibril formation, and the clinical severity of mutations. Calorimetric investigations are proposed to elaborate the mechanism of hydroxyproline stabilization of the triple-helix,

22


and studies are proposed to further investigate the recently established sequence related modulation of triple-helix twist. An important goal is to establish a peptide system to model the self-association of triple-helices, since collagens function in supramolecular assemblies and some collagen mutations are pathological because of their influence on higher order structure. Strategies to design self-associating peptides will include pairs of oppositely charged residues to promote in register arrays and adaptation of sticky end and repeating pattern designs to form staggered arrays. Studies are proposed on peptide models of type I collagen mutations leading to a bone disease (osteogenesis imperfecta) and of type VII collagen mutations leading to a blistering skin disease (dystrophoic form of epidermolysis bullosa). The effect of the immediate sequence environment of the mutation and the identity of the residue replacing the Gly will be examined. Placing collagen structure, dynamics, and folding in a solid physicochemical framework through peptide studies will provide a context for understanding normal biological activities of selfassociation and binding, and for the changes occurring in many diseases affected by this abundant protein.

Project Title: TARGETED PROGENITOR CELL ENGRAFTMENT Principal Investigator & Institution: Caplan, Arnold I.; Professor; Biology; Case Western Reserve University 10900 Euclid Ave Cleveland, Oh 44106 Timing: Fiscal Year 2002; Project Start 21-SEP-2001; Project End 31-JUL-2006 Summary: (provided by applicant): Bone marrow contains mesenchymal progenitor cells that we have called mesenchymal stem cells (MSCs). The MSCs have been shown to have the capacity to differentiate into a variety of unique mesenchyrnal tissues including bone, cartilage, muscle, fat, tendon, marrow stroma, and other connective tissues. Osteogenesis Imperfecta (OI) is a disease that is caused by mutations in the type I collagen gene. One of the progeny of MSCs, the osteoblast, is responsible for fabricating bone and, thus, a mutation in the type I collagen gene can result in bone with physical and mechanical properties that are compromised depending on the exact location and extent of the mutation. One possible curative therapy for OI is to transplant and optimize the engraftment of allogenic MSCs whose type I collagen genes are normal. As a first step to develop a procedure for effectively delivering genetically normal progenitor cells to bone for a variety of NEW therapeutic purposes, including OI, a new cell targeting strategy has been developed. The progenitor cells are modified by non-genetic insertion of macromolecules containing tissue addresses that transiently occupy positions on the outer most surface of the cell. The addition of these addressing macromolecules has been called CELL PAINTING. A newly developed, simple Cell Painting technology involves coating cells with palmitated Protein-A and then exposing these cells to a fusion protein containing the Protein A-binding FC portion of antibodies and a tissue targeting peptide. These tissue targeting peptide address assemblies are removed from the cell surface by normal mechanisms of membrane turnover within 48 to 72 hours and are thus, harmless in a long-term sense. The Objective of the research proposed here is to optimize the Cell Painting technology and to identify the most effective bone- or bone-marrow-specific addressing peptides to optimize engraftment. The HYPOTHESIS that we will focus our experimentation on is that marrow derived mesenchyrnal progenitor cells delivered back to the marrow in a specific and effective manner will engraft in sufficient numbers to effect the bone physiology of the hosts and provide a curative therapy for OI.

Project Title: TREATMENT OF OSTEOPENIA IN CHILDREN WITH CEREBRAL PALSY Principal Investigator & Institution: Henderson, Richard C.; Professor; Orthopaedics; University of North Carolina Chapel Hill Aob 104 Airport Drive Cb#1350 Chapel Hill, Nc 27599 Timing: Fiscal Year 2002; Project Start 25-SEP-2002; Project End 29-SEP-2004 Summary: (provided by applicant): Osteopenia resulting in fractures with minimal trauma is a common problem in many pediatric conditions such as osteogenesis imperfecta, juvenile idiopathic osteoporosis, muscular dystrophy, and myelodysplasia (spina bifida). As part of the North American Growth in Cerebral Palsy Project (NAGCePP) we have extensively studied one such group of children, those with cerebral palsy (CP), to better define the prevalence, causes, and consequences of osteopenia in this condition. Bisphosphonates are a group of medications utilized to treat osteoporosis in elderly adults. There are published reports of these agents used in assorted pediatric conditions, but with rare exception these are anecdotal, uncontrolled case reports involving at most a few children. We have recently completed a small placebo-controlled Pilot Trial to assess the safety and efficacy of intravenous bisphosphonates to treat low bone density in children with severe CP. At the conclusion of the 18-month study period bone density in the distal femur had increased 89% + 21% (mean + SE) compared to 9% + 6% in controls. No clinically significant adverse effects were identified. The Pilot Trial raises many questions with regards to dosing (frequency, duration, amount, route of administration), indications for treatment, long-term risks and benefits including the effect on fracture rate. The results of the Pilot Trial provide the justification for a larger scale Future Clinical Trial to answer these many questions. The purpose of this application is to support the Clinical Trial Planning Project, a process critical to the successful implementation and completion of the Future Clinical Trial. The Clinical Trial Planning Project will focus on building from both the Pilot Trial and the existing NAGCeP collaboration in several areas. Subjects: Develop additional recruiting strategies for larger numbers of subjects and further refine criteria for inclusion based on analysis of fracture risk data. Intervention: Select alternative drugs and dosing regimens that are more practical. Outcomes: Further evaluate and adapt DXA technology to this population with contractures, scoliosis, metallic implants, involuntary muscle spasms, retardation, and other characteristics that present unique challenges. Collaborative Resources & Infrastructure: Adapt and expand our existing NAGCePP network (eg database, safety monitoring) to incorporate the Future Clinical Trial.

Project Title: USE OF HAMMERHEAD RIBOZYMES IN MURINE MODELS OF OL Principal Investigator & Institution: Wenstrup, Richard J.; Professor; Children's Hospital Med Ctr (Cincinnati) 3333 Burnet Ave Cincinnati, Oh 45229 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2008 Summary: (provided by applicant): The overall goal of these studies is to test the ability of self-cleaving multimeric ribozyme constructs to ameliorate phenotypic features of osteogenesis imperfecta (OI). We propose that the dominant-negative effect of "structural" or non-excluded type I collagen mutations associated with the most severe forms of OI must be taken into account in all strategies aimed at correcting the collagen defects in those patients, and that elimination of mutant alleles must be highly efficient, since even low levels of mutant allelic products can have a major deleterious effect.

24


Experiments described in this proposal are designed to advance our development of ribozyme genes that effectively target type I collagen mutations typically observed in severe OI patients. In particular, self-cleaving multimeric ribozyme expressing genes will be designed and tested. These may provide sufficiently high ribozyme delivery to target cells so that a greater degree of allelic selectivity can be designed into ribozyme subunits that would ultimately be targeted against heterozygous single nucleotide substitutions. Experiments described in this proposal include: (1) design and testing of self-cleaving multimeric hammerhead ribozyme(s) that selectively cleave adjacent to a unique deletion junction in the human proa1(I) collagen minigene pMG155. Preliminary testing of the ribozymes' efficiency will be performed by RNase protection in vitro. Target constructs will be stably expressed in MC3T3-E1 cells for in cellulo ribozyme testing. Cleavage efficacy and reversal of a well-defined biochemical phenotype in minigene-expressing MC3T3-E1 cells will be demonstrated by Northern and Western blot analysis, pulse-chase labeling of procollagens, and measurement of several markers of cellular differentiation. Transgenic mice that express either pMG155 or the most optimal multimeric ribozyme expression gene will be mated, and the phenotypes of doubly transgenic mice will be compared to those of mice expressing only the target sequence or the ribozyme; (2) similar in vitro, in cellulo, and in vivo testing will be performed on multimeric ribozymes, that target glycine mutations created in modified versions pMG155 containing an in-frame, 270 bp eDNA segment from the 3' end of the triple helical domain of the murine colla2 gene; and (3) we will test possible additive therapeutic benefits of targeting a potential downstream mediator of the OI dominant negative phenotype, osteocalcin, in mice transgenic for a collagen minigene and optimal ribozyme construct targeting both the minigene and osteocalcin.

CHAPTER 2. NUTRITION AND OSTEOGENESIS IMPERFECTA Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and osteogenesis imperfecta.

Finding Nutrition Studies on Osteogenesis Imperfecta The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail: [email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “osteogenesis imperfecta” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

7

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

Purpose - Excerpt: Osteogenesis Imperfecta is a genetic disorder occurring in children causing abnormally fragile bones. Patient's with osteogenesis imperfecta often suffer fractures from minimal trauma. These patient's can have deformities of long bones, blueness of the white portion of the eye (sclerae), weak ligaments, and deafness due to diseased bones in the inner ear (otosclerosis). Growth deficiency is a hallmark feature of Osteogenesis Imperfecta. Growth patterns have been defined for some of the different types of Osteogenesis Imperfecta. At about 1 year of age, children with Types III and IV Osteogenesis Imperfecta show a predictable leveling off (plateau) of their growth rate. Children with Type IV Osteogenesis Imperfecta begin to resume normal growth rate at about four to five years, but they will not "catch up" to a normal height. Children with Osteogenesis Imperfecta Type III will remain at a leveled off growth rate. The reason for the leveling off (plateau) of the growth rate is unknown. The purposes of this study will concentrate on four areas of research; genetics, rehabilitation, growth, and the natural history of the multiple secondary features of Osteogenesis Imperfecta. This study will be broken up into 2 steps or phases. Phase I will focus on children from birth to age 5, and Phase II will concentrate on children ages 5 - 18 years. One of the objectives in Phase I will be to determine the effects of long leg bracing in children with osteogenesis imperfecta. The study will observe the patient's ability to do activities while standing upright as well as the development of manual skills. In addition the study will observe the alignment of the patient's bones and the bone strength and density. Study Type: Observational Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00001594 •

Growth Hormone Therapy in Osteogenesis Imperfecta Condition(s): Dwarfism; Osteogenesis Imperfecta Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Child Health and Human Development (NICHD) Purpose - Excerpt: Growth deficiency is a key feature of severe Osteogenesis Imperfecta (OI) and a frequent feature of mild to moderate forms of the disease. The reason that children with OI are short is not fully understood. We do know that details such as the number of fractures suffered or the type of OI do not fully explain the short stature of OI. Growth patterns have been defined for children with OI Types I, III, and IV. At about 12 months of age, children with Types III and IV OI demonstrate a predictable plateau of their linear growth rate. Type IV OI children begin to resume a normal growth rate at about age four to five years, but they will not "catch up" to a normal height, as they have "lost" a significant period of growth. The plateau usually continues for children with Type III OI. The reason for this growth plateau is unknown. There have been no studies which evaluate the growth of OI children in this age range. Our previous studies of growth in OI children have begun at age 5 years. We have studied growth in OI children for the past 10 years. Different medications have been tried to both stimulate growth and improve bone density. Some children have responded to growth hormone (their growth rate increased by at least 50%) and some did not. The majority of children who did respond were Type IV. However, we need to carefully treat and study more children to try to determine which children will benefit from growth hormone medication. The Goals of this Study Are: 1. We want to try to find a cause for the growth plateau common in types III and IV OI. Long-term, our goal is to develop a treatment to eliminate this plateau. 2. We want to see how long and how well

Clinical Trials 85

OI bone will respond to growth stimulation. 3. We hope to find a "predictor" for who will respond to growth hormone and who will not, by measuring your child's endocrine and growth hormone function before receiving any growth hormone treatment. 4. We want to measure the effects of growth stimulation on bone density, and the quality of OI bone. 5. We want to see if there are long term benefits resulting from this treatment in the form of final adult height, trunk height, and possibly improved function of the respiratory system. Median Subject Age (on p. 1 of webpage): 1-15 years (replaces 0-20) Phase(s): Phase II Study Type: Interventional Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00001305 •

Pamidronate to Treat Osteogenesis Imperfecta in Children Condition(s): Osteogenesis Imperfecta Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Child Health and Human Development (NICHD) Purpose - Excerpt: This study will evaluate the effect of pamidronate-a drug that decreases bone resorption (breakdown)-on osteogenesis imperfecta. This is a genetic disorder of collagen, the major protein in bone. The abnormal collagen causes weak bones, and children with severe osteogenesis imperfecta sustain many fractures throughout their lives. They also have growth deficiency, curvature of the spine, crumbling teeth, hearing loss, easy bruising and heart and lung problems. The study will compare bone density, quality and strength, final adult height, trunk height, and functional ability in children who receive 1) pamidronate every 3 months, 2) tpamidronate every 3 months + growth hormone injections, 3) pamidronate every 6 months, or 4) pamidronate every 6 months + growth hormone injections. Children 2 years of age and older with severe osteogenesis imperfecta (types III and IV) may be eligible for this study. Those enrolled will be randomly assigned to groups according to age; children two to four years of age will be randomly assigned to receive pamidronate every 3 or every 6 months. Children four years of age and older may participate in the growth hormone treatment groups. These children will continue on growth hormone until they reach their adult height or fail to grow as much as would be expected for someone on growth hormone. Patients will be followed in the clinic every 3 months for a history, physical examination, X-rays, blood tests, and measurements (weight, head circumference, and bone lengths). Children will receive a 3 to 4 hour infusion of pamidronate through an intravenous catheter (thin flexible tube placed in a vein) once a day for 3 days each visit. (Once inserted, the catheter is left in place to avoid multiple needle sticks for administering the drug and collecting blood samples.) Children who are taking growth hormone will be given the drug at the first treatment visit. At that time, the accompanying parent will be instructed on how to mix the drug and give injections. The child receives an injection 6 days a week (Sunday off). Phase(s): Phase III Study Type: Interventional Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00005901

CHAPTER 6. PATENTS ON OSTEOGENESIS IMPERFECTA 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 “osteogenesis imperfecta” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on osteogenesis imperfecta, we have not necessarily excluded non-medical patents in this bibliography.

Patents on Osteogenesis Imperfecta By performing a patent search focusing on osteogenesis imperfecta, 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. 9Adapted

Novel intronic sequences of five human genes, COL1A1, COL1A2, COL9A1, COL9A2, and COL9A3 are described. Methods of determining the existence in a subject of a pathological condition associated with an altered gene encoding a Type I or Type IX collagen protein chain are provided, wherein such pathological conditions include diseases and disorders which are known to be associated with an altered gene encoding a Type I or Type IX collagen protein chain. Primers, probes, and methods of detecting a genetic predisposition of a subject for a pathological condition associated with an altered gene encoding a Type I or Type IX collagen protein chain are provided. Diseases and disorders for which the methods and compositions of the invention are useful for diagnostic or prognostic purposes include, but are not limited to osteoporosis, osteoarthritis, chondrodysplasia, multiple epiphyseal dysplasia, osteogenesis imperfecta, shortness of stature, scoliosis, low bone density, and degenerative joint disease. Excerpt(s): The field of the invention is detecting altered collagen gene sequences. The collagen genes are an important family of genes, the products of which provide the extracellular framework for virtually all multicellular organisms (Bornstein et al., 1980 Ann. Rev. Biochem. 49:957-1003). More than nineteen distinct types of collagen have been described (Ramirez et al., 1985, Ann. New York Acad. Sci. 460:117-129; Vuorio et al., 1990, Annu. Rev. Biochem. 59:837-872; Chu et al., 1993, In: Connective Tissue and Its Heritable Disorders, Royce et al., eds., Wiley-Liss, New York, pp.149-165; Prockop et al., 1995, Annu. Rev. Biochem. 64:403-434). The biosynthesis of collagen has been described (Prockop et al., 1979, N. Eng. J. Med. 301:13-23). Large collagen structures form by nucleated growth of collagen chains into triple helical collagen subunits. Collagen fibrils form by nucleated growth of collagen subunits, a fibril comprising a quarter-staggered array of subunits (Gross et al., 1958, Annu. Rev. Cell Biol. 2:421-457; Wood et al., 1960, Biochem. J. 75:588:598; Prockop et al., 1984, N. Eng. J. Med. 311:376-386; Kadler et al., 1987, J. Biol. Chem. 262:15696-15701; Na et al., 1989, Biochem. 28: 7153-7161; Kadler et al., 1990, Biochem. J. 268:339-343; Prockop et al., 1989, Biophysics (Eng. Transl. Biofizika) 3:81-89). During nucleated growth, the collagen protein chains fold into the triple helical conformation that is a unique and characteristic feature of all collagens (Engel, 1987, Adv. Meat. Res. 4:145-158; Engel et al., 1991, Annu. Rev. Biophys. Biophys. Chem.

Gene transfer into bone cells and tissues Inventor(s): Bonadio; Jeffrey (Ann Arbor, MI), Goldstein; Steven A. (Ann Arbor, MI) Assignee(s): The Regent of the University of Michigan (ann Arbor, Mi) Patent Number: 5,763,416 Date filed: February 18, 1994 Abstract: Disclosed are methods, compositions and devices for use in transferring nucleic acids into bone cells in situ. The transfer of an osteotropic gene into bone progenitor cells is described, which event is shown to stimulate the progenitor cells and to promote bone growth, repair and regeneration in vivo. These gene transfer protocols are suitable for use in transferring various nucleic acid materials into bone, and have many uses, for example, in treating various bone-related diseases and defects, such as, in promoting fracture repair, use in connection with implants, and in treating osteoporosis and osteogenesis imperfecta. Excerpt(s): The present invention relates generally to the field of bone cells and tissues and, more particularly, it concerns the transfer of genetic material into bone. In certain examples, the invention concerns the use of nucleic acids to stimulate bone growth, repair and regeneration. Methods, compositions and devices are provided for transferring an osteotropic gene into bone progenitor cells, which is shown to stimulate progenitor cells and to promote increased bone formation in vivo. This invention may be used to administer nucleic acids to bone tissue in many circumstances, including the treatment of a variety of diseases, from promoting fracture repair and bone reconstruction, to treating osteoporosis and osteogenesis imperfecta. Defects in the process of bone repair and regeneration are linked to the development of several human diseases and disorders, e.g., osteoporosis and osteogenesis imperfecta. Failure of the bone repair mechanism is, of course, also associated with significant complications in clinical orthopaedic practice, for example, fibrous non-union following bone fracture, implant interface failures and large allograft failures. The lives of many individuals would be improved by the development of new therapies designed to stimulate and strengthen the fracture repair process. Naturally, any new technique to stimulate bone repair would be a valuable tool in treating bone fractures. A significant portion of fractured bones are still treated by casting, allowing natural mechanisms to effect wound repair. Although there have been advances in fracture treatment in recent years, including improved devices, the development of new processes to stimulate, or complement, the wound repair mechanisms would represent significant progress in this area.

Transgenic mice expressing a mutated human collagen gene Inventor(s): Ala-Kokko; Leena (Philadelphia, PA), Helminen; Heikki (Philadelphia, PA), Khillan; Jaspal S. (Philadelphia, PA), Kontusaari; Sirpa (Oulu, FI), Olsen; Anne (Moraga, CA), Prockop; Darwin J. (Philadelphia, PA), Sokolov; Boris (Philadelphia, PA), Vandenberg; Philipp (Philadelphia, PA) Assignee(s): Thomas Jefferson University (philadelphia, Pa) Patent Number: 5,663,482 Date filed: March 16, 1994 Abstract: The invention is transgenic mice substantially all of whose cells contain a mutated human collagen gene. Methods for testing therapies for the treatment of osteogenesis imperfecta, osteoporosis, and chondrodysplasia are provided. Excerpt(s): This invention was made in the course of research supported in part by NIH grants AR31888 and AR39740. The Government has certain rights in this invention. U.S. Pat. No. 4,736,866 (Leder et al.) discloses a transgenic non-human eukaryotic animal, preferably a mouse, whose germ cells and somatic cells contain an activated oncogene sequence introduced into the animal, or an ancestor of the animal, at an embryonic stage. In a preferred embodiment, the chromosome of the transgenic animal includes an endogenous coding sequence, most preferably the c-myc gene, which is substantially the same as the oncogene sequence. Transcription of the oncogene sequence is under the control of a promoter sequence different from the promoter sequence controlling transcription of the endogenous coding sequence or under the control of a synthetic promoter sequence. Gene fusions were made using the mouse myc gene and the MMTV LTR. The MMTV-myc plasmids were digested with SalI and EcoRI and separately injected into the male pronuclei of fertilized one-cell mouse eggs. The injected eggs were then transferred to pseudopregnant mice and allowed to develop to term. At 4 weeks of age, each pup born was analyzed using DNA taken from the tail in a Southern blot analysis. The Southern blot hybridizations showed that some of the founder mice retained the injected MMTV-myc fusion. The founder animals were then mated to uninjected animals and DNA of the resulting lines of transgenic offspring was analyzed. It was found that several lines of mice carried the MMTV-myc fusion. It is taught that the animals of the invention can be used to test a material suspected of being a carcinogen by exposing the animal to the material and determining neoplastic growth as an indicator of carcinogenicity. It is also taught that the invention can be used as tester animals for materials thought to confer protection against neoplasms. Stacey et al., Nature, 332: 131-136 (1988) disclose transgenic mice bearing an engineered mutant pro.alpha.1(I) collagen gene. Two mutations were produced in a mouse COL1A1 genomic clone, both of which resulted in a substitution of a glycine residue at position 859 of the.alpha. 1(I) chain by either a cysteine or an arginine. Mutagenesis of the cloned gene was carried out by replacement of the wild-type DNA region between BstEII and SfiI restriction sites at positions 2623 and 2641 by double stranded synthetic oligodeoxyribonucleotides. The final constructs contained the complete coding region of the gene linked to one of four promoters: one-kilobase (kb), 2.5-kb and 3.7-kb fragments 5' of the mouse COLIA coding region, or the Maloney murine leukemia virus long terminal repeat promoter region. The mutant constructs were transferred into either NIH3T3 fibroblasts or into Mov13 homozygous fibroblasts which do not express the pro.alpha.1(I) collagen chain. Cultured cells expressing the mutant constructs produced type I collagen with the same biochemical characteristics as mutant collagens produced by cells from patients with perinatal lethal osteogenesis imperfecta. To determine whether the mutant constructs would generate a dominant phenotype similar to the

Patents 93

human disease, DNA from the 3.7 kb-promoter Gly-Cys mutant cosmid was microinjected into fertilized eggs which were allowed to complete development in utero. It was found that none of the mice surviving birth was positive for the transgene. In contrast, almost all of the fetuses which died shortly before or after delivery carried copies of the mutant gene suggesting that the mutant gene exerts a dominant lethal effect.

Patent Applications on Osteogenesis Imperfecta As of December 2000, U.S. patent applications are open to public viewing.10 Applications are patent requests which have yet to be granted. (The process to achieve a patent can take several years.) The following patent applications have been filed since December 2000 relating to osteogenesis imperfecta: •

Use of statins to inhibit formation of osteoclasts Inventor(s): Baragi, Vijaykumar Mahalingappa; (Ann Arbor, MI), Devalaraja, Radhika; (Ann Arbor, MI), Peters, Brandon R.; (Fraser, MI), Renkiewicz, Richard Raymond; (Novi, MI) Correspondence: Francis J. Tinney; Warner-lambert Company; 2800 Plymouth Road; Ann Arbor; MI; 48105; US Patent Application Number: 20030055101 Date filed: September 10, 2002 Abstract: A method for inhibiting the formation of osteoclasts comprising administering a therapeutically effective amount of a statin to a mammal in need thereof as well as pharmaceutical compositions, kits for containing such compositions comprising a statin or a method of treating or preventing a disease state selected from the group consisting of: osteoporosis, Paget's disease, osteolysis, hypercalcemia of malignancy, osteogenesis imperfecta, osteoarthritis, alveolar bone loss, side effects of immunosuppressive therapy, and side effects of chronic glucocorticoid use by inhibiting the formation of osteoclasts comprising administering a therapeutically effective amount of a statin to a mammal in need thereof. Excerpt(s): The present invention relates to the use of statins to inhibit the formation of osteoclasts, in particular, the use of atorvastatin to inhibit the formation of osteoclasts as well as pharmaceutical compositions, kits for containing such compositions comprising a statin and a method of treating or preventing a disease, such as, for example, osteoporosis, Paget's disease, osteolysis, hypercalcemia of malignancy, osteogenesis imperfecta, osteoarthritis, alveolar bone loss, and side effects of immunosuppressive therapy and chronic glucocorticoid use by inhibiting formation of osteoclasts. Maintenance of bone density is a dynamic process wherein osteoclasts resorb and osteoblasts resynthesize the bone, Parfitt A M, Riggs B L, Melton L J, Osteoporosis: etiology, diagnosis and management, New York: Raven Press, 1988;13:501. An imbalance between resorption and formation leads to bone loss, in conditions such as osteoporosis and Paget's disease. Other conditions and diseases affected by this imbalance include osteolysis, hypercalcemia of malignancy, osteogenesis imperfecta,

osteoarthritis, alveolar bone loss or side effects of immunosuppressive therapy and chronic glucocorticoid use. The bone loss is partly a consequence of enhanced osteoclastogenesis--a series of events that includes differentiation, migration, fusion, and survival of osteoclasts. Osteoclasts, the multinucleated giant cells, develop from hematopoietic cells of macrophage lineage as a result of increased production of osteoclastogenic cytokines by osteoblasts/stromal cells, Suda T, Takahashi N, Martin T J, Modulation of osteoclast differentiation, Endocr. Rev., 1992;13:66-80; Chambers T J, Revell P A, Fuller K, Athanasou N A, Resorption of bone by isolated rabbit osteoclasts, J. Cell Sci., 1984;66:383-399; Takahashi N, Udagawa N, Suda T, A new member of TNF ligand family, ODF/OPGL/TRANCE/RANKL, regulates osteoclast differentiation and function, Biochem. Biophys. Res. Commun., 1999;256:449-455; and Suda T, Takahashi N, Udagawa N, Jimi E, Gillespie M T, Martin T J, Modulation of osteoclast differentiation and function by the new members of the TNF receptor and ligand families. Endocr. Rev., 1999;20:345-357. Of the various osteoclastogenic cytokines, macrophage colony stimulating factor (M-CSF) and receptor activator of NF-kB ligand (RANKL) are considered to be essential for osteoclast development, Jimi E, et al., Osteoclast function is activated by osteoblastic cells through a mechanism involving cell-to-cell contact, Endocrinology, 1996;137:2187-2190; and Lacey D, et al., Osteoprotegerin ligand murine osteoclast survival in vitro and in vivo, Am. J. Pathol., 2000;157:435-448. Several different therapeutic agents have been used to treat bone loss associated with osteoporosis; however, little is known about their mechanism of action. Recent studies indicate that perturbation of the cholesterol biosynthetic pathway has a direct effect on osteoclasts. Nitrogen-containing bisphosphonates, for example, are reported to inhibit formation and promote apoptosis of osteoclasts by preventing protein prenylation, a rate-limiting step in the cholesterol biosynthesis pathway, Cummings S, Bauer D C, Do statins prevent both cardiovascular disease and fracture?, J. Am. Med. Assoc., 2000;283:3255-3257; Wang P S, Solomon D H, Mogun H, Avorn J, HMG-CoA reductase inhibitors and the risk of hip fractures in elderly patients, J. Am. Med. Assoc., 2000;283:321 1-3216; Meier C R, Schlienger R G, Kraenzlin M E, Schlegel B, Hershel J, HMG-CoA reductase inhibitors and the risk of fractures, J. Am. Med. Assoc., 2000;283:3205-3210; Russell R G, Rogers M J, Frith J C, et al., The pharmacology of bisphosphanates and new insights into their mechanisms of action, J. Bone Miner Res., 1999;14:53-65; Reszka A A, Halasy-Nagy J M, Masarachia P J, Rodan G A, Bisphosphanates act directly on the osteoclast to induce caspase cleavage of mst1 kinase during apoptosis: a link between inhibition of the mevalonate pathway and regulation of apoptosis-promoting kinase. J. Biol. Chem., 1999;274:34967-34973. Inhibition of HMGCoA reductase, an early step in the cholesterol biosynthesis, by statins would be expected to have similar effects on osteoclasts. On the contrary, Mundy G, et al., Stimulation of bone formation in vitro and in rodents by statins, Science, 999;286: 194649 have shown that administration of statins in vivo increases bone morphogenic protein-2 (BMP-2) levels, which in turn results in increased bone formation. Similarly, simvastatin and lovastatin were reported to stimulate a greater dose-dependent increase in total bone area compared to established growth factors such as BMP-2 or basal fibroblast growth factor (b-FGF) in both normal and ovariectomized (OVX) rats (see U.S. Pat. No. 6,022,887). Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Website: www.bh.com. PRICE: $110.00. ISBN: 0723610568. Summary: This chapter on musculoskeletal disorders is from a text that covers the general medical and surgical conditions relevant to the oral health care sciences. The authors note that the jaws and temporomandibular joints are part of the skeletal system, but are rarely involved by systemic disease and few skeletal diseases affect the management of the dental patient directly. Muscle disorders are relatively uncommon and involvement of the masticatory (chewing) and facial muscles is not necessarily a prominent feature. However, for patients with musculoskeletal disease, access to the dental clinic or getting into or out of the chair may be difficult. Topics include genetic skeletal diseases, osteogenesis imperfecta, achondroplasia, cleidocranial dysplasia, osteopetrosis (Albers Schonberg disease), Marfan's syndrome, Ehlers Danlos syndrome, diseases of calcium metabolism and bone, rickets and osteomalacia, osteoporosis, William's syndrome, tumoral calcinosis, fibrous dysplasia, Paget's disease of bone (osteitis deformans), osteoarthritis, rheumatoid arthritis, Felty's syndrome, juvenile rheumatoid arthritis (childhood polyarthritis), psoriatic arthritis, Lyme disease, gout, ankylosing spondylitis, Reiter's disease, prosthetic joint replacements, genetic myopathies, polymyositis and dermatomyositis, and cranial arteritis and polymyalgia rhematica. For each condition, the authors discuss general aspects, diagnosis and management issues, dental aspects, and patient care strategies.

Fax (615) 936-5013. PRICE: $55.00 plus shipping and handling. ISBN: 096314393X. Summary: This chapter, from a textbook on amplification for children with auditory deficits, discusses special considerations for children with fluctuating or progressive hearing loss. One consideration, particularly for younger children, is that audiologists may assume that changes in audiometric results reflect attention or nonsensory factors, as opposed to true changes in hearing sensitivity. The author attempts to raise the reader's level of suspicion for fluctuating or progressive hearing loss in children by reviewing several causes and patterns of such changes. The causes discussed include genetic hearing loss without associated abnormalities, including autosomal dominant progressive SNHL, x-linked progressive hearing loss, and otosclerosis; genetic hearing loss with associated abnormalities, including Albers-Schonberg disease, Alport's syndrome, branchio-oto-renal (BOR) syndrome, CHARGE syndrome, mucopolysaccharidosis syndrome (MPS), neurofibromatosis, osteogenesis imperfecta, retinitis pigmentosa, Stickler syndrome, and Waardenburg's syndrome; acquired hearing loss, including prenatal causes such as infections or inner ear malformations, perinatal causes such as hyperbilirubinemia and persistent pulmonary hypertension of the newborn, and postnatal causes, such as autoimmune inner ear disease, Meniere's disease, meningitis, otitis media, and perilymphatic fistula. The author makes

recommendations for the audiologic management of children with fluctuating or progressive hearing loss. The chapter concludes with the presentation of three relevant case reports. 4 figures. 124 references. •

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 osteogenesis imperfecta. 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 osteogenesis imperfecta. 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,

112


etc.). The following drugs have been mentioned in the Pharmacopeia and other sources as being potentially applicable to osteogenesis imperfecta: Growth Hormone •

Systemic - U.S. Brands: Genotropin; Genotropin Miniquick; Humatrope; Norditropin; Nutropin; Nutropin AQ; Protropin; Saizen; Serostim http://www.nlm.nih.gov/medlineplus/druginfo/uspdi/202269.html

Commercial Databases In addition to the medications listed in the USP above, a number of commercial sites are available by subscription to physicians and their institutions. Or, you may be able to access these sources from your local medical library.

Mosby’s Drug Consult Mosby’s Drug Consult database (also available on CD-ROM and book format) covers 45,000 drug products including generics and international brands. It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/.

PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee. If you have any questions about a medical treatment, the FDA may have an office near you. Look for their number in the blue pages of the phone book. You can also contact the FDA through its toll-free number, 1-888-INFO-FDA (1-888-463-6332), or on the World Wide Web at www.fda.gov.

Coffee Break: Tutorials for Biologists19 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.20 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.21 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 Osteogenesis Imperfecta In the following section, we will discuss databases and references which relate to the Genome Project and osteogenesis imperfecta. 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).22 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. 19 Adapted 20

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. 21 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. 22 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.

To access the Entrez system at the National Center for Biotechnology Information, go to http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?CMD=search&DB=genome, and then select the database that you would like to search. The databases available are listed in the drop box next to “Search.” Enter “osteogenesis imperfecta” (or synonyms) into the search box and click “Go.” Jablonski’s Multiple Congenital Anomaly/Mental Retardation (MCA/MR) Syndromes Database23 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 Database24 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 23

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 “osteogenesis imperfecta” (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 osteogenesis imperfecta 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 osteogenesis imperfecta. 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 osteogenesis imperfecta. 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 “osteogenesis imperfecta”:

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 osteogenesis imperfecta. 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

PRICE: Single copy free from local Arthritis Foundation chapter (call 800-283-7800 for closest local chapter); bulk orders may be purchased from address above. Summary: This fact sheet for people with osteogenesis imperfecta (OI) presents an overview of this group of inherited disorders. It explains how OI results from an alteration in either the chemical makeup or production of collagen, and that the most common feature of OI is brittle bones that break easily. The fact sheet describes the types of OI and their symptoms, and it discusses ways to reduce the severity of symptoms. The fact sheet also addresses special considerations applying to children with OI, highlights research efforts, and provides information on the Arthritis Foundation.

Fast Facts on Osteogenesis Imperfecta Source: Osteogenesis Imperfecta Foundation. 1999. 3 p. Contact: Available online from Osteogenesis Imperfecta Foundation. Website: www.oif.org. Summary: This fact sheet provides information to patients on osteogenesis imperfecta (OI), a genetic disorder marked by abnormal fragility of the bones due to a genetic defect that affects the body's ability to produce collagen. As many as 50,000 people in the US may be affected by OI. Diagnosis may be based on clinical features and confirmed by collagen and DNA testing. The clinical features of types I, II, III, and IV OI are listed. Treatment for OI focuses on preventing fractures and controlling other symptoms. Mobility aids are used for patients with severe OI. Rodding surgery, used to strengthen and prevent deformity in the long bones, is frequently used. Patients with OI should exercise when possible and maintain a healthy weight. Patients should avoid smoking, alcohol, caffeine, and steroids.

•

Caring for Infants and Children With Osteogenesis Imperfecta Source: Osteogenesis Imperfecta Foundation. February 2002. 11 p. Contact: Available online from Osteogenesis Imperfecta Foundation. Website: www.oif.org. Summary: This fact sheet provides parents of children with osteogenesis imperfecta (OI) with guidelines on caring for their child. Most forms of OI are caused by imperfectly formed bone collagen that results from a genetic defect. Symptoms vary according to the form of OI. The severity of symptoms varies between individuals. The fact sheet outlines the common features of the disease. It also addresses issues that parents need to consider after learning that their child has OI. Topics include choosing and using car seats and strollers, handling, selecting clothing, bathing, recognizing and handling fractures, caring for a cast, teaching a child with OI to be independent, helping him or her achieve maximum mobility by using mobility aids, encouraging physical therapy, using braces, walking, managing symptoms, receiving special educational

130


services, and integrating a child with OI into a regular classroom. The fact sheet also addresses the importance of keeping a precise record of the child's X-rays and the importance of dental care. A list of additional resources and readings is appended. •

What People With Osteogenesis Imperfecta Need to Know About Osteoporosis Source: Osteogenesis Imperfecta Foundation. 2003. 2 p. Contact: Available online from Osteogenesis Imperfecta Foundation. Website: www.oif.org. Summary: This fact sheet provides patients with osteogenesis imprefecta (OI) with information for preventing osteoporosis. Osteoporosis is a disease in which bone mass decreases causing the risk of fracture to increase. Patients should eat a diet containing proper amounts of calcium and vitamin D for their body size; perform weight bearing exercises including walking, dancing, and swimming after consulting with their doctor or a physical therapist; and avoid smoking or consuming alcoholic beverages. Because patients with OI may have a lower bone mineral density (BMD) when compared to peak bone measurements of young adults, they should have their bone mineral density measured in early middle age in order to provide a standard in which to measure any later changes in bone density. Patients should consult their doctor about using medications that can help prevent bone loss and increase bone mass.

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 osteogenesis imperfecta. 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.

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.25

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

158


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.

The vestibule contains the utricle and saccule, organs which are part of the balancing apparatus of the ear. [NIH] Vestibulocochlear Nerve: The 8th cranial nerve. The vestibulocochlear nerve has a cochlear part (cochlear nerve) which is concerned with hearing and a vestibular part (vestibular nerve) which mediates the sense of balance and head position. The fibers of the cochlear nerve originate from neurons of the spiral ganglion and project to the cochlear nuclei (cochlear nucleus). The fibers of the vestibular nerve arise from neurons of Scarpa's ganglion and project to the vestibular nuclei. [NIH] Vestibulocochlear Nerve Diseases: Diseases of the vestibular and/or cochlear (acoustic) nerves, which join to form the vestibulocochlear nerve. Vestibular neuritis, cochlear neuritis, and acoustic neuromas are relatively common conditions that affect these nerves. Clinical manifestations vary with which nerve is primarily affected, and include hearing loss, vertigo, and tinnitus. [NIH] Veterinary Medicine: The medical science concerned with the prevention, diagnosis, and treatment of diseases in animals. [NIH] Villi: The tiny, fingerlike projections on the surface of the small intestine. Villi help absorb nutrients. [NIH]

Viral: Pertaining to, caused by, or of the nature of virus. [EU] Virus: Submicroscopic organism that causes infectious disease. In cancer therapy, some viruses may be made into vaccines that help the body build an immune response to, and kill, tumor cells. [NIH] Viscera: Any of the large interior organs in any one of the three great cavities of the body, especially in the abdomen. [NIH] Visual field: The entire area that can be seen when the eye is forward, including peripheral vision. [NIH] Vitreous Humor: The transparent, colorless mass of gel that lies behind the lens and in front of the retina and fills the center of the eyeball. [NIH] Vitro: Descriptive of an event or enzyme reaction under experimental investigation occurring outside a living organism. Parts of an organism or microorganism are used together with artificial substrates and/or conditions. [NIH] Vivo: Outside of or removed from the body of a living organism. [NIH] Volition: Voluntary activity without external compulsion. [NIH] White blood cell: A type of cell in the immune system that helps the body fight infection and disease. White blood cells include lymphocytes, granulocytes, macrophages, and others. [NIH]

Windpipe: A rigid tube, 10 cm long, extending from the cricoid cartilage to the upper border of the fifth thoracic vertebra. [NIH] Withdrawal: 1. A pathological retreat from interpersonal contact and social involvement, as may occur in schizophrenia, depression, or schizoid avoidant and schizotypal personality disorders. 2. (DSM III-R) A substance-specific organic brain syndrome that follows the cessation of use or reduction in intake of a psychoactive substance that had been regularly used to induce a state of intoxication. [EU] Wound Healing: Restoration of integrity to traumatized tissue. [NIH] Xenograft: The cells of one species transplanted to another species. [NIH] X-ray: High-energy radiation used in low doses to diagnose diseases and in high doses to treat cancer. [NIH] Yeasts: A general term for single-celled rounded fungi that reproduce by budding. Brewers' and bakers' yeasts are Saccharomyces cerevisiae; therapeutic dried yeast is dried yeast. [NIH] Zygote: The fertilized ovum. [NIH] Zymogen: Inactive form of an enzyme which can then be converted to the active form, usually by excision of a polypeptide, e. g. trypsinogen is the zymogen of trypsin. [NIH]
