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 aflatoxin 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 aflatoxin, 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 aflatoxin, 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 aflatoxin. 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 aflatoxin, 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 aflatoxin. The Editors

CHAPTER 1. STUDIES ON AFLATOXIN Overview In this chapter, we will show you how to locate peer-reviewed references and studies on aflatoxin.
Federally Funded Research on Aflatoxin The U.S. Government supports a variety of research studies relating to aflatoxin. 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 aflatoxin. 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 aflatoxin. The following is typical of the type of information found when searching the CRISP database for aflatoxin: •
Project Title: ADDUCT INDUCED FRAMESHIFT MUTAGENESIS Principal Investigator & Institution: Stone, Michael P.; Professor; Chemistry; Vanderbilt University 3319 West End Ave. Nashville, Tn 372036917 Timing: Fiscal Year 2002; Project Start 15-FEB-1992; Project End 31-DEC-2003 Summary: The goal is to understand relationships between conformational perturbations of DNA which has been adducted by endogenous and exogenous

chemical mutagens, and the subsequent biological processing of adducted DNA, e.g., during error-prone replication. We seek to understand what features of adduct structure promote frameshifts vs. substitutions. Using a frameshift-prone sequence from the Salmonella typhimurium hisD3052 gene, we will examine whether the primary adduct of malondialdehyde, M1G, induces frameshift mutations as a consequence of the ability of duplex DNA to spontaneously ring-open this adduct to its derivative N2-(3-oxo-lpropenyl)-dG. We propose that N2-(3-oxo-l- propenyl)-dG induces/promotes strand slippage structures subsequent to incorporation of dCTP, possibly as a consequence of the positioning of the propenyl moiety in the minor groove of the duplex, fostering dissociation/reassociation of the polymerase due to potential disruption of protein DNA interactions involving the thumb region of the polymerase. We will examine the potential formation of DNA crosslinks by the N2-(3-oxo-l-propenyl)-dG derivative. We will examine why the planar intercalated trans-8,9-dihydro-8-(N7-guanyl)-9hydroxyaflatoxin B1 adduct is not a strong inducer of frameshifts, using the codon 249 sequence of the p53 tumor suppressor gene, which has been linked to human cancer via aflatoxin-induced G yields T mutations. This adduct stabilizes DNA, and perhaps discourages strand slippage intermediates, which we propose reduces the propensity for frameshifts. The adduct may not disrupt minor groove interactions between DNA polymerase and the duplex. We will compare this adduct with its imidazole ringopened derivative, the FAPY adduct, which induces greater stabilization of the DNA duplex. We will examine structural hypotheses to explain the G yields T and G yields A transitions induced by the trans-8,9-dihydro-8- (N7-guanyl)-9-hydroxyaflatoxin B1. A proposed mechanism for the "signature" 5'-neighbor mutation C yields T will be examined. Our working hypothesis posits that the adduct alters or inhibits extension following the correct incorporation of cytosine, possibly by misaligning the primer terminous for further extension.

Principal Investigator & Institution: Townsend, Craig A.; Professor; Chemistry; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2003; Project Start 01-FEB-1978; Project End 31-MAR-2008 Summary: (provided by applicant): Studies of the potent environmental carcinogen aflatoxin B1 will be continued. This mycotoxin enters the food supply through contamination of grains by the molds Aspergitlus fiavus, A. parasiticus and A. nomius, which produce this compound as a normal metabolite. Chronic ingestion leads to liver tumors that are a major cause of premature death in Asia, Africa and Central America. A direct link has been forged between the interaction of the metabolically activated form of the toxin and DNA, particularly at a "hot spot" in the p53 gene leading to mutation of the encoded protein. Alterations in p53 are associated with ca. 50% of human cancers. An understanding of its biosynthesis presents problems of fundamental interest in

bioorganic chemistry and may afford means to control the occurrence of this environmental hazard. The investigation has two major goals. The first seeks understanding of fungal Type t polyketide synthases (PKSs)-how iterative function is accomplished, how "programming" is achieved to control polyketide chain length, cyclization geometry and oxidation state. A particularly interesting example of this class lies at the heart of aflatoxin biosynthesis in a complex of the PKS with two specialized yeast-like fatty acid synthase (FAS) subunits in a catalytic complex, NorS. The function of NorS will be examined both in "dissection" experiments using expressed domains of the PKS and FASs, and with the intact recombinant subunits themselves. A newly developed algorithm (UMA) to identify linker regions in multidomainal proteins will guide the experiments to examine function, physical association and structure of domains individually and in groups. The second goal focuses on the three principal oxidative skeletal rearrangement steps that characterize the progression of the biosynthetic pathway from the initially formed anthraquinone to the final substituted coumarin of aflatoxin B1. These are the rearrangement of averufin to l'hydroxyversicolorone, versicolorin A to demethylsterigmatocystin, and Omethylsterigmatocystin to aflatoxin. Gene disruption experiments have identified as many as 3 proteins mediating a single transformation, but in each case a particular cytochrome P450 has been identified. The mechanisms of these reactions are of interest in themselves, and in the broader context of acetogenin biosynthesis. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: ALDO-KETO REDUCTASES AS PART OF CHEMICAL STRESS RESPONSE Principal Investigator & Institution: Barski, Oleg A.; Pediatrics; Baylor College of Medicine 1 Baylor Plaza Houston, Tx 77030 Timing: Fiscal Year 2002; Project Start 17-AUG-2000; Project End 31-JUL-2004 Summary: Aldo-keto reductases provide protection against environmental and nutritional toxins and carcinogens by detoxification of reactive aldehydes capable of modifying cellular macromolecules. Chemical stress induces the expression of a number of detoxification enzymes. Thus, aflatoxin reductase is induced by ethoxyquin and other antioxidants. Recently it was shown that ethoxyquin and antiobiotic tunicamycin also induce aldehyde reductase, another member of the aldo-keto reductase family. A crucial element of the human aldehyde reductase gene promoter binds transcription factor CHOP, which is induced in cells exposed to chemical stress. Preliminary results suggest that CHOP mediates the induction of aldehyde reductase expression and that both aflatoxin and aldehyde reductases are part of the cellular chemical stress response system, hence their expression is induced in response to toxic insult. The application proposes to: a) evaluate the ability of physiologically relevant compounds to induce aldehyde reductase expression and to find out whether induction of both reductases goes through the CHOP-dependent pathway. B) test the compounds of the two major groups: toxic substrates and chemoprotectors that are known to induce aflatoxin reductase and other drug metabolizing enzymes (e.g. glutathione-S-transferase). C) test the Selected stimuli for their ability to induce CHOP. D) determine whether CHOP plays a role in inducing aflatoxin and aldehyde reductase by testing the effect of CHOP overexpression and deficiency, and known CHOP-inducing agents on the of the reductases expression. e) clone and sequence aflatoxin reductase promoter and examine it for a CHOP-binding element and response elements described to direct antioxidant induction in other detoxification genes. Understanding the nature and mechanism of regulation of aldehyde and aflatoxin reductase expression will potentially assist in the

prevention of harmful and carcinogenic effects of toxic aldehydes as well as provide a basis for identifying populations with increased susceptibility to certain environmental agents. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: ANALYTICAL CHEMISTRY CORE Principal Investigator & Institution: Wishnok, John S.; Senior Research Scientist; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 07-APR-1993; Project End 31-MAY-2007 Summary: (provided by applicant): This Core operates as a service, a developmental laboratory, and a resource for the Program Project. Both the overall objectives and the specific aims of the Core laboratories follow primarily from those of the individual projects; e.g., development of methods for identification or quantitation of carcinogennucleic acid adducts, carcinogen-protein adducts, and carcinogen metabolites and/or their conjugates. This includes continued evaluation of capillary HPLC-LIF for quantitation of protein or DNA damage and continued development of capillary HPLC and nanoelectrospray/microelectrospray tandem MS techniques to characterize and quantitate modified proteins or DNA. Development or adaptation of methods to quantitate DNA or protein adducts or urinary levels of PhIP or 2-amino-3,8dimethylimidazo-[4,5-f]quinoxaline (MeIQx) or their metabolites during previous funding periods, for example, was in direct response to the needs of epidemiological studies that evolved into Project 1 in this proposal. Many of the methods listed below were adapted or developed by the Core in this context and some methods, such as quantitation of aromatic amine-hemoglobin adducts by NICI GC-MS have in some cases become the methods of choice for other laboratories that carry out related investigations. The specific aims of the various research projects involve quantitation in urine, physiological fluids or tissue, of DNA and protein adducts of several carcinogens including aflatoxin and aromatic amines and related compounds (e.g., alkylated anilines) and quantitation of urinary excretion of the food-related carcinogen, PhIP, and its metabolites or conjugates. Literature methods are often based on pure or in vitro samples, so methods are developed for the isolation or concentration of low levels of these compounds in complex biological mixtures using, for example, solid-phase extractions or affinity chromatography. Where necessary, for example with tandem MS methods for analyses of modified oligonucleotides, the developmental work is done in the Core laboratories. Specific objectives for additional analyses or techniques include: (1) development and applications of ultrasensitive MS methods for nucleobase and deoxyribonucleoside adducts; (2) development and applications of HPLC-LIF methods for quantitation of derivatized adducts; and (3) transfer of HPLC-LIF technology to the Johns Hopkins University (Project 1 and Core).

Project Title: BIOLOGICAL MARKERS OF AFLATOXIN EXPOSURE Principal Investigator & Institution: Santella, Regina M.; Professor; Environmental Health Sciences; Columbia University Health Sciences Po Box 49 New York, Ny 10032 Timing: Fiscal Year 2002; Project Start 01-JAN-1990; Project End 30-JUN-2005 Summary: (provided by applicant): This project will continue to focus on the identification of environmental and genetic risk factors for development of hepatocellular carcinoma (HCC) in Taiwan. We have demonstrated that, in conjunction with hepatitis B or C virus (HBV and HCV) infection, aflatoxin B1 (AFB1), 4-

aminobiphenyl, and polycyclic aromatic hydrocarbons (PAH), increase HCC risk. Synergistic interactions between virus and chemical were also observed. Deletion o glutathione S-transferase M1(GSTM1) further increased risk in exposed subjects. The current proposal will focus on a case-control study nested in a cohort established by our collaborator Dr. Chien Jen Chen in which 25,611 subjects were recruited and a total of approximately 350 HCC cases will be identified by the end of the next four years. We will analyze blood samples from cases and controls for urinary aflatoxin metabolites and AFB1- and PAH-albumin adducts as markers of exposure. We will also begin to investigate the role of oxidative stress in risk for HCC by analyzing for variants in genes that encode enzymes with pro-oxidant and anti-oxidant activities. damage from ROS and carcinogenic metabolites that are not detoxified may be prevented from contributing to carcinogenesis by DNA repair; thus, we will extend our investigation of genetic susceptibility to DNA repair genes in the base excision and nucleotide excision repair pathways. We hypothesize that cases will more frequently be carriers of "higher risk" alleles than controls and that there will also be an interaction between environmental exposures and genotype. Finally, we will carry out a small exploratory study to determine whether tumor DNA can be detected in plasma of HCC cases. Other studies have demonstrated that tumor DNA circulating in blood contains the same genetic alterations as are found in the tumor. We will begin to investigate this phenomena in our HCC cases specifically looking at p.53 mutations and methylation of p16. These pilot studies will allow us to determine whether tumor DNA can be found at a high enough frequency to be useful in diagnosis and studies of etiology, when in the cancer process they are detectable.

Project Title: BIOSTATISTICS/EPIDEMIOLOGY CORE Principal Investigator & Institution: Munoz, Alvaro; Associate Professor; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 07-APR-1993; Project End 31-MAY-2007 Summary: (provided by applicant): During the previous 2 cycles of this Program Project on "Molecular Biomarkers for Environmental Carcinogens," the investigators have established close links with the Projects which have led to several publications. As part of the renewal of the Program Project, they will continue to collaborate with investigators of Projects in the Program Project for the design of studies using specimens collected as part of previous studies, for the analysis of data, and for the development of methods relevant to the issues of the research Projects. The design and analysis of the experiments and studies to be conducted under the auspices of the Program Project will benefit by the inclusion of expertise in biostatistics and epidemiology. The specific aims of the Biostatistics/Epidemiology Core are: (1) To establish methods that promote adherence to standard protocols with particular attention to data collection and management. The Biostatistics/Epidemiology Core will assist with the selection of appropriate samples for testing; monitor data entry; implement data editing procedures design a data base to expedite analysis and linkage of the different projects; and establish systems for data security and backup. (2) To collaborate with investigators in the Projects of the Program Project for the purpose of data analysis. Data from the projects will require the implementation of multivariate (e.g., exposure to aflatoxin, HBV status and p53 mutation on codon 249) regression methods for analyses of longitudinal data and for binary and continuous outcomes. Furthermore, they will use methods for the evaluation of treatments administered in clinical trials using changes of biomarkers as the primary outcome measure. (3) To develop new statistical methods

appropriate for the data generated by the Projects which will allow for testing and estimating parameters relevant to the specific aims of the Program Project. First, they will investigate the use of sequential designs to minimize sample testing. Second, a salient feature of the data from the proposed Projects is that most biomarkers will be a mixture of discrete (% undetectable) and continuous (level among those detectable) components. Methods that treat the data as left censored, as opposed to assigning all undetectable observations a given value, are preferred and will be developed and implemented as part of this application.

Project Title: CATALYTIC AND STEREOSELECTIVE C-C BOND FORMING REACTION Principal Investigator & Institution: Hoveyda, Amir H.; J. T. & P. Vanderslice Millennium Profes; Chemistry; Boston College 140 Commonwealth Ave Newton, Ma 02467 Timing: Fiscal Year 2002; Project Start 01-MAY-1992; Project End 30-APR-2005 Summary: (Applicant's Description) Efficient and selective preparation of organic molecules is critical to the synthesis of therapeutics. Thus development of catalytic and stereoselective addition of alkylmetals to olefins stands as an important objective. Catalytic olefin alkylation offers a practical and inexpensive route for synthesis of C-C bonds; these reactions require readily available substrates and alkylmetals. A catalytic enatioselective version would be most useful especially if it were to afford molecules that are readily amenable to further functionalization. Similar to carbomagnesation, the reactions proposed herein are Zr-catalyzed, but they proceed by an entirely different mechanism and will be significantly more general. In catalytic carbometalations reported to-date, the alkyl group of the alkyl metal is typically incorporated within the final product; here it is the alkyl moiety of an electrophilic reagent that is transferred to the product. Thus, the new Zr-catalyzed reactions are unusual: there is efficient reaction between the alkene substrate and the electrophile, but there is little or no reaction between the alkylmetal and the electrophile. The following specific objectives will be pursued: I. Development of regio- and stereoselective Zr-catalyzed alkylation and carbometalation of olefins with alkyl electrophiles. Mechanistic evidence from our previous studies will be used to develop unique methods for catalytic regio- and diastereoselective synthesis of C-C bonds. These transformations offer a new approach to C-C bond formation, where readily available olefinic substrates, alkylmetals and electrophiles can be used. II. Development of diastereoselective intramolecular Zrcatalyzed electrophilic alkylations and carbometalations. The intramolecular version of the Zr-catalyzed alkylation should allow for an unprecedented and efficient synthesis of various carbo- and heterocycles with high regio- and diastereoselectivity. III.Development of Zr-catalyzed enantioselective electrophilic alkylations and carbometalations. We will develop a catalytic and asymmetric alkylation and carbometalation of olefins with various electrophiles. These transformations offer unique and selective routes to the enantioselective synthesis of easily functionalizable molecules. The utility of the new methods will be demonstrated by synthesis of anticancer LY300502, antispastic baclofen, anti-fungal aflatoxin B2, antidepressant gemfexine and anti-leukemic helianane.

Project Title: CHEMOPREVENTION OF GREEN TEA POLYPHENOL ON LIVER CANCER Principal Investigator & Institution: Wang, Jia-Sheng; None; Texas Tech University Box 42013 Lubbock, Tx 79409 Timing: Fiscal Year 2003; Project Start 16-JUN-2003; Project End 31-MAY-2008 Summary: (provided by applicant): The long-term goal of this revised application is to design effective prevention strategies for reducing the incidence of liver cancer in highrisk populations. Primary liver cancer, mainly hepatocellular carcinoma (HCC), is one of the most common cancers in Asia and Africa. The poor prognosis of this malignancy results in it being the third most common cause of cancer deaths in the world. Chronic infection with hepatitis B viruses (HBV) and dietary aflatoxin exposure are two major etiologic risk factors for HCC in high-risk areas. The great challenge in cancer prevention and control is how to manage those who have already been exposed to carcinogens, such as individuals who are HBsAg carriers and have long-term aflatoxin exposure. Chemoprevention has been proposed as the good tool to target these high-risk populations. Among various identified chemopreventive agents, green tea polyphenols (GTP) have been shown to be safe and high effective in inhibition of carcinogen-induced mutagenesis and tumorigenesis in bioassays and animal models for different target organ sites, including aflatoxin-induced liver tumors. The specific aims for this study are (1) to incorporate molecular biomarkers analysis for aflatoxin exposure, HBV infection, and oxidative DNA damage into an on-going randomized, double blinded, and placebocontrolled intervention trial of GTP in 1,800 residents who are double seropositive of HBsAg and aflatoxin-albumin adduct in Fusui County, Guangxi Zhuang Autonomous Region, People's Republic of China; efficacy of the chemopreventive trial will be determined by monitoring changes of levels of risk-factor specific molecular biomarkers and the actual incidence of HCC in the studied population. (2) to examine and assess the efficacy of GTP in reducing aflatoxin biomarkers by measuring aflatoxin-albumin adducts in serum and various aflatoxin biomarkers in urine collected from 300 participants in different time of the study. Difference in metabolic phenotypes/genotypes as they related to aflatoxin biomarker levels will be determined.

The results of this study would help to evaluate the chemoprotective effect of GTP against human HCC and to understand the molecular mechanisms of GTP in chemoprevention of human HCC caused by well-defined major risk factors.

Project Title: CHLOROPHYLLS AS TRANS-SPECIES BLOCKING AGENTS Principal Investigator & Institution: Bailey, George S.; Distinguished Professor & Center Directo; Oregon State University Corvallis, or 973391086 Timing: Fiscal Year 2003; Project Start 17-MAR-2003; Project End 28-FEB-2008 Summary: This Project aims to compare in depth the mechanisms and dose-response characteristics for two plant-based blocking agents, native chlorophyll (Chla) and its derivative Cu-chlorophyllin (CHL). Our working hypothesis is that these agents act in vivo primarily via strong non-covalent complexation with carcinogens having
10
Aflatoxin
complementary planar aromatic structure, thereby reducing carcinogen uptake and systemic bioavailability. Though CHL studies have progressed to an initial clinical intervention trial against aflatoxin B1 (AFB1), its mechanisms against this and other carcinogens are not fully defined. We recently showed native Chla to also strongly reduce dibenzo(alpha,1)pyrene (DBP)-DNA adduction in trout, but beyond this promising result, almost nothing is known of Chla chemoprevention in vivo. Finally, since few if any blocking agents are 100% effective, additional strategies are needed to fully abrogate the effects of genotoxins such as AFB1 and DBP. To address these issues we use 5 models: AFB1 hepatic tumors in rats; AFB1 hepatic tumors in trout; the trout multi-organ DBP model; DBP rat mammary tumors; and human 14C-AFB2 exposures. AIMS 1A-C compare CHL and Chla efficacy in four tumor models, including a 10,000 trout dose-dose matrix design to test the molecular dose hypothesis that Chla-mediated reduction in DNA adduct biomarkers quantitatively predicts tumor outcome over all DBP doses. AIM 1D investigates CHL and Chla effects on AFB2 uptake in humans. AIM 2 compares CHL and Chla protective mechanisms, both systemic (complex stoichiometry and stability; degree and specificity of effects on carcinogen pharmacokinetics; predictivity of complex Kd on CHL efficacy) and cellular (P450 inhibition; electrophile destabilization). AIM 3 investigates combined chemoprevention as a strategy to supplement the incomplete blocking effects of chlorophylls. It examines initiator-specificity and basic mechanisms of tumor suppression in trout, and establishes quantitative interactions between CHL as a blocking agent and ellagie acid (EA) or tea catechins as suppressing agents in the trout stomach tumor model. It provides the first dose-dose matrix quantification of tumor suppression ever conducted, and provides a model to establish rigorously if CHL blocking and EA/tea suppression are synergistic in combined chemoprevention.

Principal Investigator & Institution: Essigmann, John M.; Professor of Chemistry & Toxicology; Division of Toxicology; Massachusetts Institute of Technology Room E19750 Cambridge, Ma 02139 Timing: Fiscal Year 2002; Project Start 01-JUL-1998; Project End 30-JUN-2003 Summary: The stated goal of the work is to investigate the mechanisms by which sample alkylating agents and the potent human live carcinogen aflatoxin induce mutations. Natural bases in the genome of viruses of plasmids will be replaced by DNA adduct known to be formed by alkylating agents and by aflatoxin. The genomes containing adducts at specific sites will be constructed by using a combination of chemical synthesis and recombinant DNA techniques. Following their construction, the modified genomes will be introduced into bacterial or mammalian cells, where the adducts will be exposed to and processed by the natural repair and replicative systems of the host. Progeny will be isolated and characterized for the type and frequency of mutation induced at or near the original site of the adduct. The genetic requirements for mutagenesis will be characterized, as will the ability of the adduct to affect survival. This study can help to rank the genetic threats posed by the various DNA adducts formed by DNA-damaging agents. With aflatoxin, the hypothesis being tested is that some feature of the mutational spectrum of aflatoxin will correlate with the type of mutations induced by one or more of the DNA adducts. With alkylating agents, previous work has defined the types of mutations induced by the most mutagenic adducts. The field has now progressed to a deeper level of biochemical detail, in which

Principal Investigator & Institution: Williams, Gary M.; Professor; Pathology; New York Medical College Valhalla, Ny 10595 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2005 Summary: (provided by applicant): The overall objective of the proposed research is to examine the hypothesis that phenolic compounds can act as anticarcinogens at low levels by blocking the cellular effects of carcinogens that operate as reactive electrophiles. In testing this hypothesis, we will conduct a series of in vivo studies in rats with the widely used analgesic acetaminophen (APAP), which has demonstrated anticarcinogenic properties in colon. As model carcinogens in the rat, 3,2'-dimethyl-4aminobiphenyl (DMAB) and 2-amino-3-methyl-3H-imidazo [4,5-f]quinoline (IQ) will be used to produce a moderate level of initiation in rat colon as well as liver. We will establish the ability of low levels of APAP to inhibit the early carcinogen-induced effects that underlie initiation of colon and liver carcinogenesis, such as enhanced cell proliferation, decreased apoptosis and induction of preneoplastic lesions, and will study the mechanism(s) of this inhibition, focusing on blocking of intracellular reactivity of the carcinogens (i.e., adduct formation). These experiments will be pursued in three specific aims as follows: 1. Define low doses of the carcinogens 3,2'-dimethyl-4-aminobiphenyl (DMAB) and 2-amino-3-methyl-3H-imidazo[4,5-f]quinoline (IQ) that produce a moderate level of initiation in rat colon and liver to be studied for inhibition by low levels of APAP; 2. Establish the dose responses for inhibition of carcinogen-induced initiation by low levels of APAP against selected doses of carcinogens in order to determine conditions for mechanistic studies and 3. Determine whether low levels of APAP inhibit initiation by reduction of formation of IQ DNA adducts in order to gain insight into potential mechanisms of anticarcinogenicity. These experiments will provide the basis for future studies of prophylaxis against human carcinogens, such as aflatoxin B1. In addition, these experiments will provide support for the epidemiological observations of reduced cancer risk associated with the use of APAP.

Project Title: CPG METHYLATION AND MUTATION Principal Investigator & Institution: Pfeifer, Gerd P.; Professor; City of Hope National Medical Center Duarte, Ca 91010 Timing: Fiscal Year 2002; Project Start 01-JUL-2000; Project End 30-JUN-2004 Summary: Mutations in p53 from different human cancers show mutagenic patterns that are presumed to provide insight into mutagenic mechanism. mC->T mutations are prominent in colon cancer, breast cancer and leukemias and are generally thought to be due to spontaneous deamination of m5C. In lung cancer there is a preponderance of G>T mutations in the non-transcribed strand of p53, which is reminiscent of mutagenesis by bulky agents, notably polycyclic aromatic hydrocarbons (PAHs) such as benzo[a]pyrene (BP). In liver cancer, which is associated with aflatoxin B1 (AFB1) exposure, there is an extraordinary hotspot (a G->T mutation at codon 249) in p53. The PI and collaborators have been involved in several significant studies, including one showing that slow DNA repair of UV damage correlated with skin cancer hotspots in
12
Aflatoxin
p53, and hotspots for BP adduction (and slow DNA repair) correlated with lung cancer hotspots in p53. Such correlations are consistent with (but not proof of) a role for these etiological agents in carcinogenesis involving p53 mutations. In this proposal, the PI wishes to investigate these associations at a deeper level by studying the effect of adduction hotspots and differential repair directly on mutagenesis (using a variety of assays) by a number of agents. The focus will be on the mechanism of CpG mutational hotspots associated with the presence of m5C. The PI proposes three specific aims. (1) Sites for DNA adduct formation, repair and mutagenesis with BP and AFB1 will be determined in a single system (fibroblasts from the Big Blue mouse having a lacI mutational target). (2) UV-, BP- and AFB1-induced mutations in a yeast p53-containing vector system will be collected and compared to p53 mutations from human tumors. (3) The PI will investigate whether C->T hotspots at CpGs might be due to one of four endogenous mutagens, which might generate mutations preferentially at m5C residues.

Project Title: DIETARY FACTORS IN THE ETIOLOGY OF CANCER IN SHANGHAI Principal Investigator & Institution: Ross, Ronald K.; Professor; Preventive Medicine; University of Southern California 2250 Alcazar Street, Csc-219 Los Angeles, Ca 90033 Timing: Fiscal Year 2002; Project Start 01-APR-1987; Project End 30-JUN-2002 Summary: (Adapted from the Applicant's Abstract): We are requesting continued support for an ongoing cohort study of 18,244 men, ages 45-64, living in a geographically defined area of metropolitan Shanghai, Peoples Republic of China. All cohort members have completed detailed diet and medical histories and have blood and urine samples. Questionnaires have been edited and computerized and blood and urine samples have been processed, aliquoted, and continuously stored at both -20_C and 70_C. The cohort was fully established in 1989. Follow-up of the cohort is proceeding through cancer registration by the population-based Shanghai Cancer Registry, by routine ascertainment of death certificates, and by annual recontact of all cohort members. As of March 1994, 606 have developed cancer and 989 have died. The leading cancers include lung, stomach, liver, and colorectal cancers, while stroke is the number one cause of death. Major accomplishments achieved through this cohort to date include: (1) the first direct evidence linking aflatoxin ingestion to human hepatocellular carcinoma (HCC); (2) strong evidence of synergy between aflatoxin biomarkers and chronic infection with hepatitis B virus in establishing risk of HCC; (3) failure to find an association between H. pylori serology and stomach cancer risk; (4) the absence of an inverse association between antioxidants and fatal stroke; and (5) the first comprehensive and systematic evaluations of smoking-related cancer incidence and mortality in China. We propose to continue to follow this cohort for an additional five years. We will continue to evaluate risk factors for major health outcomes in the cohort, building on previous observations and continuing to exploit the serum and urine banks available for biomarker studies. Although we did not collect buffy coats for genetic studies on cohort members, we have demonstrated that the stored serum samples contain sufficient cells for conducting selected PCR-based genetic studies. Among the scientific goals for the next five years are: (1) to continue to evaluate the aflatoxin/HCC association and to assess the impact of sequence variations in genes involved in aflatoxin metabolism (GSTM1 and EPHX) in modifying risk; (2) to continue to assess the role of H. pylori in gastric cancer etiology in Shanghai, and to assess the possible protective effect of tea polyphenols on risk; and (3) to better understand the complex interrelationships among carotenoids, smoking, and lung cancer and to assess the

Project Title: EPIDEMIOLOGY OF HEPATOCELLULAR HEPATITIS B VIRUS IN 3 POPULATIONS
CARCINOMA
&
Principal Investigator & Institution: London, W. Thomas.; Senior Member; Fox Chase Cancer Center Philadelphia, Pa 191112434 Timing: Fiscal Year 2002; Project Start 01-APR-2001; Project End 31-MAR-2003 Summary: (Applicant's Description) Prospective studies of 60,984 men in Haimen City, China and 19,469 men in Senegal, west Africa revealed a 14-fold greater death rate from hepatocellular carcinoma (HCC) among the Haimen (168 per 100,000) than the Senegalese cohort (12 per 100,000). Even though chronic infection with hepatitis B virus (HBV) is the major risk factor for HCC in both populations, the age-adjusted prevalence of chronic infection is about 20% in both cohorts. Exposure to aflatoxin, a postulated major risk factor for HCC, is also similar or greater in the Senegalese population. The prevalence of viremia (HBV DNA in serum) among HBV carriers throughout adult life, however, is much higher among the Chinese than the Senegalese population. Nevertheless, within the Chinese cohort, viremia at study entry is not a risk factor for HCC after four years of follow-up. The aims of this project focus on factors that may account for variation in HCC risk in the Chinese and Senegalese cohorts and a cohort of Asian-American HBV carriers living in the Philadelphia area. Continued tracking of these three cohorts will test the hypothesis that with longer duration of follow-up, H B V v iremia and liver damage at study entry are associated with person-specific risks of HCC and that aflatoxin-B1 (AFB1)-albumin adducts are a s s ociated with development of HCC among viremic individuals and/or genotypically determined poor detoxifiers of AFB1 (in collaboration with Project 2). In close cooperation with the studies of WHV in woodchucks (Project 3), an intensive longitudinal study of 1000 male and female HBV carriers in these three populations will be conducted to: a) examine whether perturbations of the stability of HBV serum markers are associated with acute illnesses, aflatoxin exposure, and/or outgrowth of viral mutants; b) assay hepatocyte turnover and immune responses in liver biopsies; c) correlate these measures with viral load; d) examine the relationship of sex differences in changes in HBV serum markers over time to the lower HCC risk of female HBV carriers. Because present studies show that an episode of acute hepatitis in adulthood approximately doubles HCC risk among both HBV carriers and non-carriers, the causes and outcomes of 200 cases of acute hepatitis in Haimen City will be characterized. This research will lead to a new level of understanding of the factors that lead to HCC and to new strategies for the prevention of this lethal disease.

Project Title: GENETIC EPIDEMIOLOGY OF PRIMARY HEPATOCELLULAR CARCINOMA Principal Investigator & Institution: Buetow, Kenneth H.; Chief; Fox Chase Cancer Center Philadelphia, Pa 191112434 Timing: Fiscal Year 2002 Summary: The risk of common cancer is produced through gene-gene, and/or geneenvironment interactions. These interactions are poorly understood for most cancers in part due to the diversity and complexity of the exposures. Primary hepatocellular

Aflatoxin
carcinoma (HCC) represents a unique opportunity to investigate a complex cancer phenotype in humans. Epidemiologic studies have firmly established the role of chronic hepatitis B virus infection (HBV) and aflatoxin B1 (AFB1) exposure as environmental risk factors. These exposures are well described and are amenable to exposure assessment. it is therefore conceptually possible to examine their relationship to host genetic constitution in determining HCC susceptibility. Significant progress has been made during the current funding period toward understanding the genetic components of the HCC complex phenotype. Statistical analyses has demonstrated familial aggregation consistent with genetic susceptibility of HCC. Comprehensive genomewide allele loss studies have identified multiple regions which could contain novel tumor suppressor genes. An interaction between host genetic constitution, HBV/AFB1 exposures, and HCC was established in c case-control study and confirmed in a cohortderived study population. It is the goal of the of the current application to continue the integrated genetic epidemiologic analysis of HCC. Familial aggregation of HCC and its relationship to HBV and AFB1 exposure will be examined in a significantly expanded collection of families. Comparative genome hybridization (CGH) will be added to permit the localization of putative tumor suppressor genes and oncogenes. Regions observed to have high frequency changes in tumors will be studied by genetic mapping methods to assess their role in familial transmission. The role of genetic variability in candidate genes that modulate responses to HBV infection and AFB1 exposure will be assessed. This will be accomplished by expressing human xenobiotic metabolizing P450 cDNAs and their polymorphic variants in Saccharomyces cerevisiae and determining which ones in combination with AFB1 cause genetic alterations. Human gene mapping methods using a family-based case-control population will be used to test the role polymorphic variants of candidate AFB1 metabolizing loci in HCC. The influence of lipotrope insufficiency and genetic variability in lipotrope metabolism to HCC related end-points will be assessed. Finally, the interaction of major susceptibility genes, risk modifying loci, and environmental exposures and their role in determining risk and familial aggregation will be examined.

Project Title: GLOBAL RESPONSES TO AFLATOXIN B1 & ALKYLATING AGENTS Principal Investigator & Institution: Samson, Leona D.; Professor; Biomedical Engineering; Massachusetts Institute of Technology Room E19-750 Cambridge, Ma 02139 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 31-JUL-2006 Summary: (provided by applicant) In response to RFA:ES-01-002, this is an application to become a member of the NIEHS-sponsored Toxicogenomics Research Consortium. The have proposed a highly integrated plan to explore the transcriptional responses of a variety of organisms, including humans, to a broad range of toxic agents found in the environment. Transcriptional profiling is expected to reveal a truly global view of how cells, tissues and animals attempt to recover, not always successfully from environmental insults. The investigators hope to learn what features of environmentally induced transcriptional responses are predictive of success or failure, and in addition to learn what features correlate with specific outcomes of toxic exposures, for instance, cell death, apoptosis, mutagenesis and carcinogenesis. The model environmental agents to be studied are Aflatoxin B1 and its metabolites, plus a range of SNI and SN2 alkylating agents. Together these agents are representative of toxic agents found in the external environment, food supply, the endogenous cellular environment, and the cancer chemotherapy clinic. The model organisms and cell systems whose transcriptional

responsiveness will be scrutinized include E. coli, S. cerevisiae, cultured rodent and human cell lines, engineered rat and mouse liver tissues, rats and mice. The investigators have integrated an in vitro tissue engineering Project into this application with the goal of developing an alternative to using animals to test for toxicity and carcinogenicity. It seems to the investigators that appropriate transcriptional responsiveness in this system represents a rigorous test of its similarity to in vivo tissues. Two platforms for mRNA profiling will be employed, namely, Affymetrix GeneChip DNA oligonucleotide microarrays, and cDNA arrays fabricated in the MIT BioMicro Center. The Microarraying and Bioinformatics Core will have its center of gravity in the MIT BioMicro Center, and this Core will serve as the focal point for three Research Projects and the Toxicology Research Core Project (TRCP). The TRCP activities will be closely aligned with the activities of the other 4 or 5 members of the Toxicogenomics Research Consortium. Together the overarching goals will be to establishing good working practices in transcriptional profiling as it relates to the area of toxicogenomics, and to contribute to the development of an extensive relational database as a repository for high quality data emerging from the field of toxicogenomics. The investigators anticipate that this research will uncover a myriad of hitherto unknown ways in which cells respond to environmental agents.

Project Title: HEPTOCYTE PROLIFERATION AND AFLATOXIN METABOLISM Principal Investigator & Institution: Sell, Stewart; Professor; Pathology and Lab Medicine; Albany Medical College of Union Univ Albany, Ny 12208 Timing: Fiscal Year 2002; Project Start 01-APR-2000; Project End 31-MAR-2003 Summary: The hypothesis that continued proliferation of hepatocytes is associated with an transgenic immature phenotype in regard to metabolism of aflatoxin (AFB1) and development of hepatocellular carcinoma (HCC) will be analyzed in p53 null and p53ser246 mutant transgenic, and HBV mice. World-wide HCC is arguably the tumor that causes the highest cancer mortality. HCCs occurring in high-risk areas of the world are associated with continued proliferation of liver cells in response to liver injury (HBV and HCV), and with aflatoxin (AFB1) exposure. AFB1/HBV associated HCCs have a high frequency of mutations in the tumor suppressor gene p53 at codon 249 (p53ser249). Recently we reported that hepatocytes of p53 null mice continue to proliferate into adulthood and do not become polyploid with aging. In addition, hepatocytes of p53ser246 transgenic mice (equivalent to p53ser249 of humans) maintain a high number of cells in G1. P53 null and p53ser246 mice also have increased susceptibility to AFB1 hepatocarcinogenesis when the carcinogen is administered during the first week of life, and HBV transgenic mice are susceptible to AFB1 carcinogenesis, even when the carcinogen is administered at one month of age when normal mice of the same strain are resistant. We wish to test the hypothesis that the changes in status of cells in the livers of these mice reflects a less-differentiated phenotype associated with increase production of carcinogenic metabolites and increased risk of HCC development in adult mice. In specific aim 1, the metabolism of AFB1 at different ages of normal and transgenic mice will be examined by AFB1 epoxide and adduct formation, glutathione-s-transferase activity and p450 isoenzyme distribution. In addition, oval cells or small hepatocytes will be isolated from cocaine-treated mice and from neonatal and adult transgenic livers to determine if there is distinctive metabolism of AFB1 in these cells. The effect of proliferation of "mature" hepatocytes will be determined using microsomes from partially hepatectomized livers, and metabolism of AFB1 by cultured liver cells at different stages of differentiation will be examined. In Specific Aim 2, AFB1 will be

Project Title: MECHANISM OF CELL DEATH INDUCED BY AFLATOXIN B1 Principal Investigator & Institution: Kosa, Jessica L.; Division of Toxicology; Massachusetts Institute of Technology Room E19-750 Cambridge, Ma 02139 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-MAY-2003 Summary: (Adapted from the Applicant?s Abstract): The goal of this study is to determine how aflatoxin B1 (AFB1) kills hepatocytes. First, I shall probe the sequence of biochemical events that leads to liver cell death. Seond, since aflatoxin is believed to exert its biological effects by inflicting DNA damage, I shall determine which of the several types of DNA damage induced by aflatoxin induces the pattern of gene expression that precedes death. Third, I shall screen for novel genes whose mRNA levels change during AFB1-induced cell death, employing a DNA microarray approach. Apoptosis is the mechanism by which the liver eliminates pre-neoplastic cells, and is known to be induced by AFB1 in transformed liver cells. Initial experiments will test the hypothesis that apoptosis is responsible for the cytotoxicity of AFB1. Expression of genes know to participate in apoptosis is responsible for the cytotoxicity of AFB1. Expression of genes known to participate in apoptosis will be examined by quantitative RT-PCR in order to identify the specific pathways involved in the induction of apoptosis, thereby establishing which genes are vulnerable to oncogenic mutations. Primary rat hepatocytes will be employed in order to model in vivo AFB1 exposure realistically. In order to pinpoint the molecular pathway from DNA damage to cell death, DNA containing the AFB1-induced lesions AFB1-N7-Gua, AFB1-FAPY, and AP sites will be introduced into hepatocytes. The impact of each lesion on cell death, and apoptosis gene expression, will be measured to determine which specific DNA adduct(s) induce cell death. Finally, a microarray of rat genes will be constructed and used to search for novel genes that are induced or repressed during AFB1-induced cell death. Genes whose expression is altered by AFB1 exposure, and especially those that appear to be co-regulated with known apoptosis genes, are likely to participate in the cellular response to the toxin.

Project Title: MITOCHONDRIAL DNA DAMAGE AND REPAIR Principal Investigator & Institution: Bogenhagen, Daniel F.; Professor; State University New York Stony Brook Stony Brook, Ny 11794 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2003 Summary: Mitochondrial DNA is a frequent target of chemical damage. Base loss, oxidative damage and reaction with carcinogenic compounds such as benzo(a)pyrene and aflatoxin are thought to occur at rates equal to or greater than the corresponding rates of damage to nuclear DNA. Mitochondria are able to repair some types of DNA damage, such as abasic sites and oxidative lesions (e.g., 8-oxo-dG), but probably not others. Very little is known concerning the enzymology of DNA repair in mitochondria. Replication through DNA adducts or attempts at repair may contribute to the incidence

of point mutations and deletions observed in a growing list of human diseases. These diseases range from point mutations associated with rare neuromuscular diseases identified with the acronyms MELAS, MERRF, and NARP to large deletions observed in Kearns Sayre Syndrome. Recent studies have found a correlation between mtDNA damage and type 11 diabetes, Parkinson's disease and aging, although more research is required to establish a role for mtDNA damage in the etiology of these conditions. We propose to investigate the effects of specifically localized lesions in DNA templates prepared by our collaborators in this project on DNA replication by the purified mitochondrial DNA polymerase gamma. These studies will employ templates containing abasic sites, 8-oxo-dG, aminofluorene and benzo(a)pyrene adducts. We will also search for accessory factors that may facilitate translesional synthesis by DNA polymerase gamma. We propose experiments to characterize enzymes involved in mtDNA repair and to attempt to reconstitute repair of abasic sites or 8-oxo-dG lesions in mtDNA. Certain lesions, such as cyclobutane pyrimidine dimers in mtDNA are not thought to be repaired efficiently. We will attempt to increase the efficiency of repair by using molecular genetic techniques to direct repair enzymes such as photolyase or T4 endonuclease (denV) to mitochondria.

Project Title: NEUTROPHILS AND HEPATOTOXICITY Principal Investigator & Institution: Roth, Robert A.; Professor; Pharmacology and Toxicology; Michigan State University 301 Administration Bldg East Lansing, Mi 48824 Timing: Fiscal Year 2002; Project Start 15-JUN-1986; Project End 31-MAR-2004 Summary: (Adapted from the investigator's abstract). The overall goal of the proposed research is to understand how the inflammatory response to gram-negative bacterial endotoxin (lipopolysaccharide, LPS) acts as a determinant of susceptibility to intoxication by xenobiotic agents. In concert with this goal, the major focus of this proposal is to understand the role of the neutrophil in LPS-induced amplification of hepatotoxic responses to xenobiotic agents. Evidence has emerged indicating that exposure to small, nontoxic amounts of LPS is an important determinant of the magnitude of response to several hepatotoxicants. Experiments in the first specific aim will determine in rats whether LPS influences the response to chemicals (e.g., aflatoxin B1, monocrotaline) that initiate hepatotoxicity by different mechanisms and produce different lesions. Neutrophils activated in tissues are likely to play an important role in the mechanism by which LPS amplifies hepatotoxic responses, and Aim 2 will address this hypothesis in vivo and in a co-culture system of neutrophils and hepatocytes (HCs). Previous studies indicate that activated neutrophils damage hepatic parenchymal cells (HCs) through the release of toxic proteases such as cathepsin G and elastase. Studies in Aim 3 will determine if cathepsin G and elastase appear in plasma before the onset of liver injury, if administration of anti-proteases prevents LPS potentiation of liver injury, if administration of the proteases into the portal vein of rats reproduces the effects of
18
Aflatoxin
LPS in vivo, and if exposure of HCs in vitro to small concentrations of selected hepatotoxicants renders these cells more vulnerable to injury from cathepsin G and elastase. Tumor necrosis factor-alpha (TNF alpha) is released during LPS exposure and has pro-inflammatory effects on both neutrophils and hepatocytes. Aim 4 will explore the role of this important cytokine in the augmentation of chemical hepatotoxicity by LPS. In Aim 5, specific protein targets of neutrophil proteases on hepatocellular plasma membranes will be identified and their association with enhanced HC injury determined. Identification of such targets will provide important clues as to cellular mechanisms by which neutrophil proteases injure hepatocytes. These studies will reveal the role of neutrophils in LPS amplification of hepatotoxicity and mechanisms by which they act to increase susceptibility to hepatocellular damage from exposure to xenobiotic agents. The results will provide new knowledge about how LPS and the inflammatory events it generates may act as a determinant of the magnitude of response to toxicants.

Project Title: REGULATION OF XENOBIOTIC-METABOLIZING CYP3A Principal Investigator & Institution: Zangar, Richard C.; Senior Research Scientist; Battelle Pacific Northwest Laboratories Box 999, 902 Battelle Blvd Richland, Wa 99352 Timing: Fiscal Year 2002; Project Start 30-SEP-1999; Project End 31-AUG-2004 Summary: (Adapted from the Investigator's Abstract) Cytochrome P450 3A (CYP3A) levels are important determinants of aflatoxin and acetaminophen toxicity and the uptake and elimination of numerous therapeutic agents. CYP3A protein has been reported to be stabilized by some CYP3A substrates. The PI reported that several structurally and functionally distinct agents that are not known CYP3A substrates alter CYP3A protein stability in primary cultured rat hepatocytes. The changes in CYP3A stability are consistent with effects of these agents on phospholipase C or D (PLC or PLD, respectively). Studies in microsomes have indicated that the PLD metabolite, phosphatidic acid (PA), is important in determining CYP3A stability. We propose to test this hypothesis that CYP3A protein stability is dependent upon microsomal PA levels and to further elucidate the molecular mechanism by which phospholipases and other enzymes that regulate PA levels contribute to CYP3A protein stability. The specific aims are: 1) To further establish the role of PLD and PLC in the regulation of CYP3A protein stability. 2) To determine if agents that alter CYP3A stability in primary cultured hepatocytes also function in in vitro incubations. 3.) To determine if PA analogs with different fatty acid moieties have distinct effects on CYP3A protein stability in microsomal samples. 4) To determine whether agents that regulate rat CYP3A stability act in a like manner in human primary cultured hepatocytes and microsomes. These studies will provide information that can be used to predict drug interactions by providing an understanding of the underlying molecular mechanisms involved in the post-translational regulation of CYP3A, and will test a new hypothesis regarding the interactions of phospholipase activities and a key drug-metabolizing enzyme.

Project Title: REMEDIATION PROCESS FOR AFLATOXIN CONTAMINATED FOODS Principal Investigator & Institution: Denvir, Adrian J.; Lynntech, Inc. College Station, Tx 77840 Timing: Fiscal Year 2002; Project Start 25-SEP-2002; Project End 25-JUN-2004 Summary: (provided by applicant): Mycotoxins are carcinogenic compounds that are produced by Aspergillus, Penicillium and Fusarium molds on agricultural produce and affect up to 25 per cent of the worlds food crops. Aflatoxins are naturally occurring mycotoxins produced by two types of mold: Aspergillus flavus and Aspergillus parasiticus. The Food and Drug Administration (FDA) has established action levels of 20 ppb for aflatoxin present in food and 0.5 ppb for aflatoxin M1 in milk. These limits are established by the Agency to provide an adequate margin of safety to protect human and animal health. As such there is an ongoing need for economic processes for detoxifying aflatoxin contaminated agricultural products intended for human and animal consumption. Remediation methods such as oxidation using ozone or ammoniation leave undesirable taste and odor residues on the product. The research in the Phase I will seek to determine the feasibility and economics of extracting aflatoxins in nuts and nut products using a cheap and environmentally benign solvent, which removes the toxin without producing or leaving toxic residues, retains nutritive value and does not alter significantly the technological properties of the nut.

Project Title: SPECIES DIFFERENCE IN THE BIOTRANSFORMATION OF AFLATOXIN Principal Investigator & Institution: Eaton, David L.; Professor and Associate Dean; Environmental and Occupational Health Studies; University of Washington Grant & Contract Services Seattle, Wa 98105 Timing: Fiscal Year 2002; Project Start 01-MAY-1991; Project End 31-JUL-2004 Summary: Numerous studies have demonstrated that biologically active, natural components of the diet may confer resistance to chemical carcinogens via induction and/or inhibition of biotransformation enzymes. In particular, specific chemical components of the diet, such as flavonoids, isocyanates, glucosinolates, indoles, dithiolthiones, and polyphenols have been identified as effective inducers and/or inhibitors of carcinogen activation/detoxification pathways in animal models. There is much supporting data from human epidemiological studies on the important relationship between diet and cancer in humans, although the diversity and complexity of the diet, and uncertainty of specific exposures, in such studies makes identification of specific active components nearly impossible. Although animal models are useful for "hypothesis testing", species differences in carcinogen activation and detoxification pathways, as well as differences in gene regulation and expression in response to inducers, make extrapolation of animal data to the human situation tentative, at best. Thus, there is a need to develop model systems that utilize human cells/tissues to determine the efficacy of specific dietary components and/or putative chemoprotectant drugs to favorably modify the biotransformation of human carcinogens. One such model human carcinogen is aflatoxin B1. Aflatoxins are mycotoxins produced by the common fungal molds, Aspergillus flavus and Aspergillus parasiticus. Worldwide, aflatoxins are considered a major public health problem because of their potent

carcinogenic effects. Human epidemiological data has documented that humans are susceptible to AFB-induced hepatocarcinogenesis, especially in combination with hepatitis B virus infection. However, there are large species differences in the susceptibility to aflatoxin carcinogenesis. Rats are highly sensitive, whereas mice are very resistant. The mechanism for this difference is associated with the expression of a specific enzyme, glutathione S-transferase A3-3 (mGSTA3-3), which is present in the livers of mice, but not rats. Treatment of rats with the drug, oltipraz, or the food additive, ethoxyquin, protects rats from aflatoxin-induced liver cancer. The mechanism for this protection is due to the ability of these chemicals to "turn on" a gene for a glutathione S-transferase, rGSTA5-5, that is normally not expressed in rat liver, but which efficiently detoxifies aflatoxin. Human liver tissue has very low ability to detoxify aflatoxin -- in fact, worse than the poor ability of rats. There has been considerable interest in devising a dietary or chemointervention strategy for humans that increases resistance to AFB by induction of GSTs. The long range goals of this proposal are to: 1) establish in vitro models that utilize isolated human hepatocytes in culture and human cDNA expressing yeast, to assess the efficacy of specific dietary components as putative chemoprotectors against AFB and other chemical carcinogens, and 2) complete the characterization of species differences in glutathione S-transferases with activity toward AFB-epoxide.

Project Title: SYMPOSIUM ON ALDO-KETO REDUCTASES & TOXICANT METABOLISM Principal Investigator & Institution: Penning, Trevor M.; Professor; Pharmacology; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-JUL-2003 Summary: (provided by applicant): This proposal is a request for financial support for a half-day symposium on "The Emerging Role of Aldo-keto reductases (AKRs) in the Metabolism of Toxic Substances" to be presented at the American Chemical Society National Meeting, Boston, MA August 18-22nd, 2002. AKRs are a superfamily of monomeric oxidoreductases that play central roles in the metabolism of aldose-sugars, prostaglandins, steroid hormones, and chemical carcinogens. Often they catalyze the conversion of carbonyl groups to alcohols so that the parent compound can be conjugated and eliminated. AKRs are highly conserved in both prokaryotes and eukaryotes. There are currently 150 proteins classified into 12 families and crystal structures exist for many of the proteins. In humans, these enzymes also catalyze the formation of hyperosmotic sugars, the detoxification of reactive a,B-unsaturated aldehydes that result from the decomposition of lipid hydroperoxides, and the metabolism of chemical carcinogens including aflatoxin dialdehyde, nicotine derived nitrosamino-ketones and polycyclic aromatic trans-dihydrodiols. Their emerging role in the metabolism of endogenous and exogenous toxins suggests that the family may be ultimately as important as the well-studied CYP superfamily in drug and xenobiotic metabolism. The speakers chosen for this symposium will cover each of the areas listed. In addition an overview of the AKR superfamily and its nomenclature (accepted by the Human Genome Project) will be given and approaches to studying functional genomics of AKRs in yeast will be presented. Each of the speakers has an international reputation in their area of expertise. The goal of the symposium will be to bring together experts in the AKR field so that they will be able to educate the scientific community concerning these enzymes with the hope of attracting new investigators to the field. Issues that are unexplored include the role of AKR isoforms in drug metabolism; their role in

chemotherapeutic drug resistance; the regulation of human AKR genes; and AKR pharmacogenomics with emphasis on human polymorphisms that may affect individual response to toxicants and susceptibility to chemical carcinogenesis. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: USE OF BIOMARKERS IN HUMAN INTERVENTIONS Principal Investigator & Institution: Kensler, Thomas W.; Professor; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 07-APR-1993; Project End 31-MAY-2007 Summary: (provided by applicant): The goals of this Project are to incorporate the use of biomarkers into primary and secondary (chemoprevention) interventions in high risk populations exposed to aflatoxins. In all preventive interventions there must be objective metrics with which to quantify success. Subsequently, the cost-benefit balance of the intervention can be analyzed and appropriately targeted toward high risk subgroups or individuals within a population. One of the tenets of the molecular epidemiology paradigm is that a mechanistic understanding of the actions of carcinogens can lead to novel prevention technologies. Therefore, the aims of this Project are 3-fold. First, it is to improve existent liquid chromatography-electrospray ionization tandem mass spectroscopy (LC-ESI-MS/MS) methodology for quantitative analysis of major urinary aflatoxin metabolites (e.g., aflatoxin-N7-guanine, aflatoxin M1, aflatoxin P1, aflatoxin-mercapturic acid). Second, it is to determine the impact of primary prevention strategies in West Africa using targeted contamination reduction strategies in community settings. The investigators will develop interventions aimed at: (1) mothers and young children during the weaning period when mycotoxin-contaminated maize-based foods are first introduced into the child?s diet; and (2) local subsistence farmers attempting to reduce contamination of their dietary staple crops, groundnuts and maize. Aflatoxin and fumonisin biomarkers will be used as outcome measures, while in part (1) the investigators will also examine the effects of intervention on child growth and immune parameters. Third, it is to follow up initial results of the investigators' chlorophyllin intervention where they demonstrated a significantly reduced excretion of aflatoxin-N7-guanine at 3 months by examining the impact of the intervention on biomarker modulation at additional time points. They will also analyze urine samples collected during the course of a one-year long intervention with oltipraz in Qidong for magnitude and persistence of modulatory effects on DNA adduct and other aflatoxin biomarkers. It is the hypothesis that levels of biomarkers for the biologically effective dose of carcinogens will be predictive of the efficacy of primary and chemopreventive interventions. The specific aims of this Project have been designed to translate the biomarkers developed and validated in Projects 1 and 4 into metrics to determine the impact of the interventions in high risk populations.

Project Title: VALIDATION AND APPLICATION OF RISK, BIOMARKERS IN HUMAN STUDIES Principal Investigator & Institution: Groopman, John D.; Associate Director of Cancer Prevention; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 07-APR-1993; Project End 31-MAY-2007 Summary: (provided by applicant): The goals of this Project are to develop and validate biomarkers of biologically effective dose and risk induced by environmental carcinogens. It is now axiomatic in human cancer that ambient exposures to multiple
22
Aflatoxin
environmental carcinogens are significant factors in the development and progression of many cancer types. Thus, an understanding of the dose-response relationships between exposure and outcomes in critical targets such as DNA may characterize disease potential. While Dr. Tannenbaum's Project has a major focus on the development of novel, sensitive methods for the detection of DNA and protein adducts, this Project extends these strategies into risk-biomarker analysis. Since there are critical genetic targets in cells, such as tumor suppressor genes, for environmental carcinogens, then it is possible that these targets might prove to be useful biomarkers for risk analysis. Cooccurring environmental exposures and genetic susceptibility may modify the above dose-response effects and consequently these parameters will also be considered. The linkage between carcinogen-induced DNA damage and heritable change in genetic targets is a cornerstone of this Program Project's paradigm. Recently, the discovery that DNA from cells undergoing apoptosis and other turnover processes is found in the blood has resulted in the ability to noninvasively measure mutations in targets such as p53 offering the potential to quantify early biological effects in risk individuals. Therefore, a combined use of biologically effective dose biomarkers, susceptibility biomarkers and genetic biomarkers might reveal the subset of high risk people within a population who will benefit from targeted interventions, which is the outcome of studies proposed in Project 3. It is the hypothesis that levels of biomarkers of biologically effective dose in combination with gene mutations are predictive of disease outcome characterizing risk in individuals. Thus, specific aim 1 is to determine the power of p53 mutations and other genetic alterations in sera using the Short Oligonucleotide Mass Analysis (SOMA) methodology combined with aflatoxin-DNA adducts in urine to predict cancer outcome and disease risk in cohorts in rural China and West Africa. Specific aim 2 is designed to extend the investigators' observations on the high level of aflatoxin biomarkers in West African children in order to assess the impact on growth and immune status, including susceptibility to hepatitis B virus (HBV) infection. West African children, unlike adults, have elevated aflatoxin biomarker levels when infected with HBV. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

AND
CYTOCHROME
P450
Principal Investigator & Institution: Buhler, Donald R.; Professor; Environ & Molecular Toxicology; Oregon State University Corvallis, or 973391086 Timing: Fiscal Year 2002; Project Start 01-SEP-2001; Project End 31-AUG-2005 Summary: (provided by applicant): Cytochrome P450s (P450s or CYPs) are a superfamily of heme-containing enzyme that catalyze Phase I oxidative, reductive and peroxidative reactions of both endogenous (steroids, fatty acids, vitamins, prostaglandins, retinoids, etc.) and exogenous substrates (chemical pollutants, drugs and carcinogen). The zebrafish (Danio rerio) has become a widely used animal model for studying embryogenesis and developmental genetics and as an animal model to investigate mechanisms of chemical carcinogenesis. Compared to rainbow trout (Oncorhynchus mykiss), however, zebrafish are relatively resistant to certain carcinogens such as aflatoxin B1 (AFB1) and dibenzo[a,1]pyrene (DBP), thus reducing their utility as carcinogenesis models. Their is considerable interest, therefore, in finding zebrafish strains that are more sensitive to carcinogens. Because of their central roles in bioactivation and metabolism processes, it also has become important to establish the contribution of different CYP forms to carcinogenesis and tumor tissue selectivity in the zebrafish and to utilize bioactivating or detoxifying CYP expression as a tool to help

select sensitive zebrafish strains. Therefore, the objectives of this project are to: 1) clone, sequence, heterologously express, enzymatically and kinetically characterize and map major zebrafish CYPs potentially involved in carcinogen activation and detoxification; 2) use zebrafish CYP isozyme specific oligonucleotide probes to determine their tissue and cell-specific expression patterns in zebrafish mutant lines used to assess the sensitivity of the fish to selected carcinogens; 3) select mutant zebrafish line on the basis of inactivating mutations of tumor suppressor genes and/or high carcinogen bioactivating CYP isoform expression; and 4) determine the sensitivity of wild-type and mutant zebrafish lines to AFB1 and DBP. This proposed work should add significantly to the foundation of CYP and carcinogenesis research in zebrafish. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.6 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with aflatoxin, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “aflatoxin” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for aflatoxin (hyperlinks lead to article summaries):
6 PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

CHAPTER 2. NUTRITION AND AFLATOXIN Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and aflatoxin.
Finding Nutrition Studies on Aflatoxin 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 “aflatoxin” (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.

CHAPTER 5. PATENTS ON AFLATOXIN 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.8 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 “aflatoxin” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on aflatoxin, we have not necessarily excluded non-medical patents in this bibliography.

Analysis of aflatoxins in peanuts by high pressure liquid chromatograph Inventor(s): Dunmire; David L. (St. Louis, MO), Otto; Susan E. (Fenton, MO) Assignee(s): Peanut Research & Testing Laboratories, Inc. (edenton, Nc) Patent Number: 4,285,698 Date filed: April 28, 1980 Abstract: A method is disclosed for quickly and easily determining the presence and concentration of aflatoxins in peanuts. Aflatoxins are extracted from ground peanuts with a methanol-water solution using a tissuemizer. The extracted sample is filtered and an aliquot of the filtrate is transferred to a separatory funnel. A salt solution is added to remove interferences. The combined aqueous solution is then extracted with dichloromethane. The dichloromethane extract is evaporated to dryness, trifluoroacetic acid is then added and the resulting residue taken up in the mobile phase. The solution is then passed through a minicolumn for filtration and final cleanup. An aliquot is then injected into a high pressure liquid chromatograph system for separation of the four aflatoxin components, B1, B2, G1 and G2. Quantitation is done using a filter fluorescence detector. Excerpt(s): This invention relates generally to the quantitative and qualitative detection of aflatoxins in peanuts and more particularly is directed towards a new and improved method for analyzing aflatoxins in peanuts by means of high pressure liquid chromatography. Aflatoxin is a known carcinogen that enters food as a consequence of the manner in which foods are grown, handled or stored. Aflatoxin is not a deliverate food additive but occurs as a natural contaminant in such common foods as peanuts and corn. Aflatoxin is a generic term referring to a group of highly toxic compounds produced by the fungus Aspergillus flavus/parasiticus. In additional to the original recognition of aflatoxins B1, B2, G1 and G2, there also have been a large number of metabolites whose structures have been examined. These are mostly produced in mammalian tissue upon ingestion by the mammal of the parent compound B1, although some may also be produced by the fungus or by chemical treatment of B1. Of the four original aflatoxins, B1 is the most common, usually comprising about 90% of the aflatoxin residue observed on contaminated foodstuffs and it is also the most toxic. The biological activity of aflatoxin B1 is relatively similar to the other aflatoxins. Web site: http://www.delphion.com/details?pn=US04285698__

Animal feed containing selected montmorillonite clay as additive and method for selecting the clay Inventor(s): Taylor; Dennis R. (Houston, TX) Assignee(s): Engelhard Corporation (iselin, Nj) Patent Number: 5,192,547 Date filed: October 1, 1990 Abstract: A correlation is established between aflatoxin B1 binding on raw montmorillonite clays and the ratio of their surface acidities divided by their porosities for surface acid sites whose pKa values fall in the range 5.0-6.8 (i.e. weakly acidic) and
Patents 129
porosities for pores whose diameters fall in the region 50-600 A. This information provides a method for preselecting clay additives for animal feeds which have enhanced toxin binding capacity. Excerpt(s): This application is related to U.S. Ser. No. 07/552,715, filed Jul. 16, 1990. This invention relates to a method for inactivating mycotoxins which may be present as contaminants in dry animal feeds by adding a selected type of montmorillonite clay. More specifically, the selected clay is a calcium montmorillonite clay in which the ratio of surface acidity (as determined by Hammett indicators in the 5.0-6.8 pKa range) to pore volume (in the 50-600 Angstrom range) is above 5 and is preferably above 10. Mycotoxins, chemical substances produced by ubiquitous fungi, can make the difference between profit and loss to the poultry and livestock industries. Animals are extremely vulnerable to mycotoxins due to the common practice of diversion of mycotoxin contaminated agricultural commodities to animal feed. Thus, mycotoxicoses, or mycotoxin-induced diseases, frequently occur in animals. Web site: http://www.delphion.com/details?pn=US05192547__ •
Apparatus and method for fumigation and detoxification of plant seed Inventor(s): Enos; Quentin M. (Chandler, AZ) Assignee(s): Toltec Corporation (phoenix, Az) Patent Number: 4,780,279 Date filed: April 14, 1987 Abstract: The present invention relates to a method of fumigation and detoxification of plant seed and to an pneumatic apparatus having a positive pressure air source, seed feed, a vacuum wheel air lock, fumigant and detoxicant source, a spraying apparatus for introducing the fumigant and/or the detoxicant and an exit cyclone having an optional air return for returning fumigant and/or detoxicant saturated air to the apparatus. The inventive apparatus and method have been found effective for aflatoxin B.sub.1 and B.sub.2 suppression as well as for insect extermination in infested plant seed. Excerpt(s): The present invention relates generally to an apparatus and method for the fumigation and detoxification of plant seed such as rice, corn, cottonseed, soybeans, peanuts, wheat, barley and other seeds. More particularly, the present invention relates to a pneumatic apparatus having a positive pressure air source, seed feed, a vacuum wheel air lock, fumigant and detoxicant source, a spraying apparatus for introducing the fumigant and/or the detoxicant and an exit cyclone having an optional air return for returning fumigant/detoxicant saturated air to the apparatus. Further, the inventive apparatus and method have been found effective for aflatoxin B.sub.1 and B.sub.2 suppression as well as for extermination of pink boll worm and weevils which commonly infest and contaminate the nation's seed supply and food chain. In addition to the efficacious fumigant and detoxicant activity of the present invention, increases in nutrient values of the treated seeds has been noted. At present time conventional means for fumigation and detoxication of the nation's seed supply has been accomplished by employing the highly toxic chemicals phostoxin and methyl bromide. Despite their inherent toxicity these two chemicals are the major fumigants and detoxicants currently employed by growers and/or seed treatment facilities to comport with the U.S. Department of Agricultural (hereinafter "USDA") regulations and requirements for qualification for the Phyto-Sanitary Certificate of Approved Fumigation which is required for interstate transport of treated seed. Current methodology and regulation
130
Aflatoxin
mandates, for example, that cotton planting seed stored for interstate transport must be covered, treated and retained in such state for at least five days before transportation from the storage area. The five day retention period has been found to be the optimum time permissible for insuring safe levels of residual phostoxin or methyl bromide toxicity. This retention period had been tremendously burdensome to cotton gins which do not have endless seed storage capacity and must, at times, abandon or ignore proper storage procedures.

Bacillus subtilis strain and prevention of aflatoxin contamination in cereals and nuts Inventor(s): Kimura; Norio (Yokohama, JP) Assignee(s): Morinaga & Co., Ltd. (tokyo, Jp) Patent Number: 4,931,398 Date filed: January 21, 1988 Abstract: A microbiological prevention of aflatoxin contamination in cereals and nuts is provided. Bacillus subtilis NK-330 and NK-C-3 effectively inhibit not only growth of aflatoxin-producing fungi including Aspergillus flavus and Aspergillus parasiticus but also production of aflatoxin by them. Excerpt(s): This invention relates to a microbiological prevention of aflatoxin contamination in cereals and nuts, in particular, to certain strains of Bacillus subtilis capable of inhibiting growth of fungi which produce aflatoxin, hereinafter referred to as "aflatoxin-producing fungi", and moreover of suppressing production of aflatoxin by them. More specifically, the invention relates to Bacillus subtilis strains NK-330 and NKC-3 and their variants. Aflatoxin is one of the most potent carcinogens among those hitherto known. Aflatoxin is a metabolite secreted by the aflatoxin-producing fungi such as Aspergillus flavus and Aspergillus parasiticus, and several homologues thereof including aflatoxin B.sub.1 and aflatoxin G.sub.1 are also known. Among food cereals such as wheat, barley, rice, corn (maize), etc. and food nuts such as hazelnut, almond, Brazil nut, peanut, etc., those contaminated with the aflatoxin have been found (cf. Am. Assoc. Cereal Chemists Inc., 595(1974); Am. Assoc. Cereal Chemists Inc., 603(1975); JAOCS, 980A, December (1981); J. Agric. Food Chem., 26, 249 (1978); Dtsch Lebensm. Rudsch., 76, 47(1980); Lebensm. -Wiss. u. -Technol., 14, 252(1981)), and the aflatoxinproducing fungous microbes are supposed to possibly spread around the areas where these crops are cultivated and yielded. Since such cereals and nuts contaminated with the aflatoxin provide a serious health problem, a lot of countries strictly regulate the importation of the contaminated cereals and nuts so as not to enter their territories.

Control of mycotoxin production by chemically inhibiting fungal growth Inventor(s): Gueldner; Richard C. (Chula, GA), Wilson, Jr.; David M. (Tifton, GA) Assignee(s): The United States of America AS Represented by the Secretary of (washington, Dc) Patent Number: 4,474,816 Date filed: October 4, 1983
Patents 131
Abstract: An effective method to control aflatoxin produced by toxic strains of Aspergillus parasiticus fungi is disclosed. An effective amount of Beta-ionone is applied to said fungi to inhibit the growth and sporulation of the fungi and thereby control production of aflatoxin from the fungi without killing the fungi. Excerpt(s): This invention relates to the control of mycotoxins by means of chemical treatment. Heretofore, it has been known that "turkey X" disease has been caused by a toxin produced by some strains of the fungi Aspergillus parasiticus. This aflatoxin which is produced by strains of A. parasiticus is acutely toxic as well as carcinogenic. However, much of the research on aflatoxin dealt solely with the detection of aflatoxin and relatively little research has been done on the prevention of formation of aflatoxins. A review of the control or suppression of fungi producing aflatoxin reveals efforts of fumigating with high level dosages of methyl bromide, ethylene dibromide, propane/propene ethylene oxide, sulfur dioxide, and phosphine and did show some effects of fungicidal activity. Ammonia proved to be fungicidal but demonstrated a lack of any residual effect. Propionic, acetic, and isobutyric acids also have antifungal activity. However, all the above chemicals have the definite disadvantage of toxicity to humans and animals, corrosiveness, and lowered nutritional quality. Therefore, they are not acceptable to either humans or animals. Web site: http://www.delphion.com/details?pn=US04474816__ •
Extraction of gossypol from cottonseed Inventor(s): Abraham; George (Metairie, LA), Fisher; Gordon S. (Metairie, LA), Hron, Sr.; Robert J. (New Orleans, LA), Kuk; Myong S. (Metairie, LA) Assignee(s): The United States of America AS Represented by the Secretary of (washington, Dc) Patent Number: 5,112,637 Date filed: November 5, 1990 Abstract: The present invention is drawn to a process for extraction of gossypol for cottonseed using a solvent solution which includes: (a) a water miscible organic solvent; (b) water; and (c) an acid which is strong enough to prevent binding of gossypol to cottonseed protein but which is not so strong as to hydrolyze a substantial portion of the cottonseed protein. The present invention also includes cotton seed meals of reduced gossypol content (and optionally reduced aflatoxin and/or fat content) produced by the aforementioned extraction. Excerpt(s): This invention relates to a solvent extraction process for removing gossypol (a toxic pigment) from cottonseed. The extraction is conducted with a solvent solution comprised of: a water miscible organic solvent, water and an acid which is strong enough to prevent gossypol from binding to cottonseed protein, but not so strong that it hydrolyses a substantial amount of the cottonseed protein. Unlike other commercial oilseeds, cottonseed contains a toxic pigment, gossypol, which prevents it from being a feed for animals, other than those that have a rumen. That is, while some whole cottonseed is fed to mature ruminants, most of it is separated into oil and meal, typically by solvent extraction using hexane. As used herein, cottonseed meal, or flour, refers to the whole residue remaining after most of the oil has been removed. Before the oil and meal can be used as a food source, the gossypol must be removed or deactivated. In addition, unfavorable growing, harvesting, or storage conditions can cause cottonseed to mold and become contaminated with a mold metabolite aflatoxin, which, because it
132
Aflatoxin
is carcinogenic, must be removed, or destroyed. The presence of such toxic components prevents cottonseed from reaching its full potential as a food source, especially in countries that grow cotton but not soybeans. In the intact cottonseed, the gossypol is concentrated in glands that are covered with a hydrophilic coating, which keeps the gossypol from coming into contact with other components of the seed. Originally, gossypol was deactivated by pressing, or expelling, the oil out of moist seeds at relatively high temperatures, such as at temperatures from about 110.degree. to 130.degree. C. Under these conditions, the glands are ruptured by hot moisture, releasing gossypol. Most of the gossypol reacts with protein, thereby forming bound gossypol, which is insoluble. The rest reacts with phospholipids and other low molecular weight components of the seed to give products that are soluble in oil and other organic solvents, as is any unreacted gossypol. The gossypol in these soluble products is referred to as free gossypol. Total gossypol is the sum of bound gossypol and free gossypol. Total gossypol content of meals made by such a process are typically from about 0.7 to 1.0 wt. %. While binding to protein is advantageous in that it acts to detoxify the gossypol, it is disadvantageous because it reduces the nutritive value of the meal by reducing the available lysine content. Currently, separation is done by expression, or by extraction of the oil from flaked kernels at elevated temperatures with a solvent such as hexane, or a combination of expression and extraction. The most common method used today is solvent extraction, but unless a separate moist heating preconditioning step is included, meals produced by this method will contain unruptured glands and excessive amounts of free gossypol. Furthermore, it is well known that adverse physiological effects can occur with some meals containing high total gossypol, even though free gossypol is within acceptable limits.

Flotation separation of aflatoxin-contaminated grain or nuts Inventor(s): Hagen; William R. (Cincinnati, OH), Henderson; James C. (Cincinnati, OH), Kreutzer; Stanley H. (Cincinnati, OH), Schmidt; Arthur A. (Cincinnati, OH), Smith; Charles A. (Cincinnati, OH) Assignee(s): The Procter & Gamble Company (cincinnati, Oh) Patent Number: 4,795,651 Date filed: May 4, 1987 Abstract: Disclosed is a method for separating mycotoxin-contaminated grains, kernels, seeds and nuts, from uncontaminated whole grain seeds, whole or split kernel nuts and seeds to obtain a substantially uncontaminated supply source of these foods. The separate contaminated source can be further processed to lower the mycotoxin contamination. The process involves the separation of the mycotoxin or aflatoxincontaining materials by floating the aflatoxin-contaminated foods in a liquid having a specific gravity of from about 0.9 to about 1.2. A highly preferred process uses dynamic flotation. Excerpt(s): This invention relates to a method for separating mycotoxin-contaminated grains, kernels, seeds and nuts, from uncontaminated whole grain seeds, whole or split kernels, nuts and seeds to obtain a substantially uncontaminated supply source of these foods. The process involves the separation by specific gravity of the mycotoxincontaining materials by floating the mycotoxin-contaminated foods in a liquid. Preferably, the separate contaminated source can be further processed to provide foodstuffs with safe levels of mycotoxin. Mycotoxins are a broad class of toxic materials
Patents 133
produced by the growth of fungi on foods. Aflatoxin is a specific mycotoxin produced by the action of a fungi belonging to the genus, Aspergillus, on grain, seeds, kernels or nuts. Aflatoxin contamination is particularly a problem in the peanut industry. In addition, aflatoxin can affect grains such as corn and hops, oilseeds, such as cottonseed, soybean, almonds, brazel nuts, pecans, pistachios, etc. The growth of fungi which produce aflatoxin is favored under the same conditions which are good for growing nuts and grains. High levels of aflatoxin in foods presents a threat to animals and humans since aflatoxins at high levels have been shown to cause cancer in laboratory animals. For this reason, the USDA has set limits on the amount of aflatoxin and other mycotoxins that can be in food products. Web site: http://www.delphion.com/details?pn=US04795651__ •
Method and apparatus for sorting agricultural products Inventor(s): Fraenkel; Herbert (London, GB2), Gough; Patrick B. (Wallington, GB2), Maughan; William S. (Burgess Hill, GB2) Assignee(s): Sortex North America, Inc. (lowell, Mi) Patent Number: 4,203,522 Date filed: August 31, 1978 Abstract: A sorting machine for sorting ground nuts affected by a mould which produces aflatoxin comprises detectors for detecting infra-red (or red) and green light respectively reflected from a ground nut being viewed. The infra-red detector produces a first signal indicative of the amount of mould carried by the ground nut. The green detector produces a signal indicative of the extent to which the ground nut is mechanically damaged, and also produces a gating signal. A comparison signal is derived from these first and second signals and is passed by way of a gate and a level detector to an ejector. The gating signal controls the operation of the gate in dependence upon the extent to which the ground nut being viewed is mechanically damaged, so that the ejector is actuated by comparison signals of a predetermined level only when the extent to which the ground nut is mechanically damaged does not exceed a predetermined value. Excerpt(s): This invention concerns a method and an apparatus for effecting relative separation between desired and undesired agricultural products, e.g. between mouldcarrying agricultural products and agricultural products free of such mould. Although the invention is applicable to the sorting of a number of different agricultural products, e.g. maize, it is more particularly applicable to the sorting of oil stock ground nuts which are liable to be contaminated by a toxic mould which produces aflatoxin. After the oil has been extracted from ground nuts, the material remaining may be formed into a cattle cake. However, if the said ground nuts have been contaminated by aflatoxin, the cattle cake made therefrom is similarly contaminated, and since aflatoxin is highly toxic, many countries have legislation which limits the permissible amount of aflatoxin in cattle cake. Attempts have been made to detoxify the cattle cake, e.g. by the use of ammonia, but the cost and the undesirable side effects of such detoxification have so far prevented its use.

Method and test kit for detecting an aflatoxin B.sub.1 and G.sub.1 using novel monoclonal antibodies Inventor(s): Dixon; Deborah E. (Lansing, MI), Hart; L. Patrick (Lansing, MI), Pestka; James J. (East Lansing, MI) Assignee(s): Neogen Corporation (lansing, Mi) Patent Number: 4,835,100 Date filed: October 31, 1986 Abstract: Novel monoclonal antibodies to an aflatoxin B.sub.1 and G.sub.1 in a test kit and used in a method of testing are described. The method for producing the monoclonal antibodies uses repeated administration of aflatoxin B.sub.1 or the related analog compound as a 1-position polypeptide to a murine and production of a hybridoma to generate the novel monoclonal antibodies. The novel antibodies have limited cross-reactivity to aflatoxins B.sub.2, G.sub.2 and M.sub.1. Aflatoxin B.sub.1 or aflatoxin G.sub.1 are detected in foods and the like using the test kit and method. Excerpt(s): The present invention relates to novel monoclonal antibodies against aflatoxin B.sub.1 and G.sub.1 and to a test kit and a method which uses these monoclonal antibodies to detect the presence of aflatoxin B.sub.1 and G.sub.1 in foods and other materials. In particular the present invention relates to monoclonal antibodies produced (1) by repeated introduction of aflatoxin B.sub.1 as a 1-position polypeptide conjugate into a murine over a period of time so that polyclonal antibodies are released into the blood serum of the murine and then (2) by the production of hybridomas from spleen cells of the murine which generate the monoclonal antibodies and which have substantially the cross-reactivity of the specific monoclonal antibody produced by hybridoma IVI-10108 to aflatoxin B.sub.1 and G.sub.1 and limited cross-reactivity to aflatoxins B.sub.2, G.sub.2 and M.sub.1. Aflatoxins are toxic metabolites produced by the fungal species Aspergillus flavus and Aspergillus parasiticus. The ability of aflatoxin B.sub.1 and its metabolites to act as potent carcinogens, mutagens and teratogens has been described (Butler, W. H. Mycotoxins p. 1-28 (1974); Chu, F. S., Adv. Appl. Microbiol. 22, 83 (1971)). Interest in development of rapid sensitive assays for detection of aflatoxins has been steadily increasing, since the compounds are known to occur naturally in peanuts, corn, milk, wheat, and animal rations (Butler, W. H. Mycotoxins p. 1-28 (1974)). Use of high performance liquid chromatography has been described for quantitation of aflatoxins (Gregory, J. F. and Manley, D. B., J. Assoc. Off. Anal. Chem. 65, 869 (1982); Stubblefield, R. D. and Shotwell, O. L., J. Assoc. Anal. Chem. 60. 4066 (1977)). Several drawbacks to using this procedure as a quick screening method include the high cost of the instrumentation, the need for extensive sample clean up, and only single samples may be analyzed at one time. A number of immunoassays using polyclonal antiserum have been described for detection of aflatoxin B.sub.1 (Chu, F. S. and Ueno, I. Appl. Environ. Microbiol. 33, 1125 (1977); El-Nakib, O., Pestka, J. J. and Chu, F. S., J. Assoc. Off. Anal. Chem. 64, 1077 (1981); Langone, J. L. and Van Vunakis, H., J. Natl. Cancer Inst. 56, 591 (1976); Lawellin, D. W., Grant, D. W. and Joyce, B. K., Appl. Environ. Microbiol. 34, 94 (1977); Pestka, J. J., Gaur, P. K. and Chu, F. S., Appl. Environ. Microbiol. 40, 1027 (1980); and Pestka, J. J. and Chu, F. S., J. Fd. Prot. 47, 305 (1984)). The advantages offered by these assays include a reduction in assay time, simplified extraction procedures, an increase in assay sensitivity, and the ability to routinely screen large numbers of samples.

Method for detecting aflatoxin in almonds Inventor(s): King, Jr.; A. Douglas (Martinez, CA), Schade; John E. (Walnut Creek, CA) Assignee(s): The United States of America AS Represented by the Secretary of (washington, Dc) Patent Number: 4,535,248 Date filed: August 24, 1984 Abstract: Aflatoxin contamination in almonds is detected by exposing almond kernels to long wave ultraviolet light and detecting the presence of aflatoxin as determined by violet-purple fluorescence. The method is particularly adaptable to automation to detect and sort out aflatoxin contaminated almonds. Excerpt(s): This invention relates to and has among its objects the provision of a novel method for detecting aflatoxin contamination in almonds. Aflatoxins, a group of highly toxic substances produced by certain species of Aspergillus, especially A. flavus, have been found to occur in agricultural products such as corn, cottonseed, a variety of oilseeds, and many varieties of nuts. Experimental studies indicate that aflatoxins are acutely toxic to most animal species. The extreme toxicity of aflatoxin is demonstrated by the fact that the LD.sub.50 of the B.sub.1 component is less than 30 micrograms for day-old ducklings. Animals which consume sublethal quantities of aflatoxin for several days or weeks develop a subacute toxicity syndrome which commonly includes moderate to severe liver damage. Prolonged administration of the toxin at subacute levels leads to formation of cancerous liver tumors. Data accumulated from feeding tests indicate that the effective dose of the B.sub.I component of aflatoxin for the induction of liver tumors in rats is approximately 10 mg per day. When this value is compared with similar estimates for other hepatocarcinogens such as dimethylnitrosamine (750 mg/day) and butteryellow (9,000 mg/day), the relative potency of aflatoxin is readily apparent. Aflatoxins occur at varying concentrations throughout the tissue of contaminated products and can occur at concentrations up to over 1,000,000 parts per billion (ppb) in individual nuts such as peanut kernels. These toxins may remain after the molds that produced them are removed or destroyed. Aflatoxins are fairly resistant to heat and to chemical treatments that do not destroy the nutmeat. conventional food processing, such as roasting nuts, can reduce the aflatoxin level but not sufficiently to solve the problem.

Method for detoxifying foodstuffs Inventor(s): Chapman; Russell R. (Mesa, AZ) Assignee(s): Aflatoxin Limited Partnership (cave Creek, Az) Patent Number: 5,082,679 Date filed: January 25, 1991 Abstract: An improved method for de-toxifying aflatoxin contaminated foodstuffs is provided by pre-treating the contaminated foodstuff with a wetting agent prior to exposure to the de-toxicant. An aqueous solution of detergent or soap is a suitable wetting agent which can be applied to the foodstuff by spraying or immersion. Ammonia gas is the preferred de-toxicant. Once the wetting agent has been applied, the de-toxification reaction is exothermic so that little or no heat need be added to reach the

elevated temperatures that facilitate rapid de-toxification. The process runs at atmospheric pressure in low cost vessels and may be accomplished in times of an hour or less without external heat sources. Excerpt(s): This invention concerns an improved method for de-toxifying foodstuffs and, more particularly, an improved method for de-toxifying foodstuffs containing aflatoxins and similar naturally occurring contaminants. There are many foodstuffs that are susceptible to contamination by mold and bacteria and products thereof. For example, grains and feeds that have been exposed to warm humid atmospheres can become contaminated by aflatoxins. Aflatoxins are highly toxic carcinogenic substances produced by the naturally occurring molds Aspergillus flavus and Asgergillus parasiticus. Unless the affected material is de-toxified, the aflatoxins can cause severe damage and death to animals or humans who ingest the affected foodstuffs. Hence, there is an ongoing need for economical processes for de-toxifying aflatoxin contaminated agricultural products intended for human or animal consumption. A number of techniques have already been developed for de-toxifying aflatoxin contaminated foodstuffs. The following patents and article are incorporated herein by reference and describe the results set forth below by way of example. Web site: http://www.delphion.com/details?pn=US05082679__ •
Method for obtaining aflatoxin-free food products Inventor(s): Carmona; Julian Y. (279 Guevara Avenue, San Juan, Rizal, RP), Marasigan; Marcelo P. (6-Legaspi Street, Philamlife Homes, Quezon City, RP) Assignee(s): None Reported Patent Number: 4,035,518 Date filed: October 6, 1975 Abstract: A method for obtaining food products substantially free of aflatoxin in the form of particles, kernels, and the like, is disclosed wherein a food product such as whole grain seeds or whole kernel nuts are subjected to a weakly alkaline aqueous solution maintained at elevated temperatures for a short period of time, washing the thusly treated food product with water until the wash effluent indicates that it is pH neutral and separating the aflatoxin-contaminated food product from the uncontaminated food product. The uncontaminated food product sources can then be further processed to obtain a food product ready for consumption. Excerpt(s): This invention relates to a method for separating aflatoxin contaminated kernels, seeds, nuts, and the like, from uncontaminated whole grain seeds, whole or split kernels nuts, and the like, to obtain an uncontaminated supply source for a food product. Aflatoxin is produced by the action of a fungi belonging to the genus, Asperigillus, on exposed grain seeds or nuts. Aflatoxin affects certain grains such as corn, hops, cottonseed, soybean, and the like, as well as such nuts as almonds, Brazil nuts, pecans, pistachios, peanuts, and the like, and is particularly active and dominant when such grains and nuts are grown and cultivated in wet climates. Due to the toxic threat that aflatoxin-contaminated food sources present to animals, there have been many attempts to treat grains and nuts in meal form so as to either detoxify these food sources or lower the level of their aflatoxin-contamination. Representative of such attempts are the use of photochemical means to detoxify the aflatoxin-contaminated food sources (U.S. Pat. No. 3,506,452), mixing the food source product with methylamine at elevated temperatures (U.S. Pat. No. 3,585,041), contacting the food

Method for the removal of aflatoxin from cereals, oil seeds and feedstuffs Inventor(s): Fukinbara; Itaru (Tokyo, JA), Korenaga; Tokiyoshi (Sakaimachi, JA), Yano; Nobumitsu (Tokyo, JA), Yoshida; Koji (Sakaimachi, JA) Assignee(s): Asahi Kasei Kogyo Kabushiki Kaisha (osaka, Ja) Patent Number: 4,055,674 Date filed: June 14, 1976 Abstract: A method for the removal of Aflatoxin from materials including cereals, oil seeds and feedstuffs contaminated therewith comprising contacting said materials with a mixed solvent system of liquid dimethyl ether and water. The water is employed in an amount of 2 to 8 % by weight with respect to the liquid dimethyl ether. Such method which can reduce the Aflatoxin content to 15 ppb or less, can be conducted at low temperatures so that no proteins contained therein are denaturated. Further, the spent solvent system containing Aflatoxin can be easily regenerated by contacting it with activated carbon and recycled. Excerpt(s): This invention relates to a method for the removal of Aflatoxin from cereals, oil seeds and feedstuffs which are contaminated therewith, by the use of a mixed solvent system comprising liquid dimethyl ether and water. More particularly, this invention relates to a method for the complete removal or elimination of a carcinogenic poisonous substance produced by a mold, which is named "Aflatoxin", from those cereals, oil seeds and feedstuffs contaminated with said substance through extraction in an extraction system containing liquid dimethyl ether and water. The term "cereal" as used herein means to refer to any cereals, which are normally ingestable orally in any optional form of raw or processed grains and meals such as rice and so on. The term "oil seed" as used herein means to refer to any oil seeds, which are normally edible in any optional form of raw or processed grains, meals and cakes, such as peanut, peanut meal, cotton seed, cotton seed meal, cotton seed cakes and so on. The term "feedstuff" as used herein refers to any other materials which may be employed for preparing a feed of domestic animals. It is well-known in the art of Aflatoxin is one sort of those toxins produced by a variety of molds, of an extremely high carcinogenicity and a typical one produced by a microbe belonging to Aspergillus flavus and growing on foodstuffs such as grains. It is generally realized that such materials as peanuts, cotton seeds, rice and the like are easily susceptible to contamination with this toxin and thus badly damaged thereby.

Method of inhibiting mycotoxin production in seed crops by modifying lipoxygenase pathway genes Inventor(s): Keller; Nancy P. (College Station, TX) Assignee(s): The Texas a & M University System (college Station, Tx) Patent Number: 5,844,121 Date filed: January 19, 1996 Abstract: A method of inhibiting the production of mycotoxins of fungus, such as aflatoxin-producing and sterigmatocystin-producing fungi, in plants susceptible to contamination by such mycotoxins consists of introducing into the susceptible plant a gene encoding for lipoxygenase pathway enzyme of the mycotoxin. Exemplary of the lipoxygenase pathway enzymes are soybean lipoxygenase, allene oxidase, hydroperoxide lyase and hydroperoxide dehydratase. The resulting transgenic plant demonstrates substantial resistance to mycotoxin contamination of such fungus. Plants which are substantially resistant to mycotoxin contamination of Aspergillus spp. are further obtained by incorporating into mycotoxin susceptible plant antisense genes for the 9-hydroperoxide fatty acid producing lipoxygenases. Excerpt(s): The invention is drawn to a method of eliminating or substantially reducing toxicity in seed crops caused by colonization of fungi which produce toxic fungal metabolites called mycotoxins. In particular, the invention relates to a method of eliminating or substantially reducing toxicity in seed crops caused by colonization of aflatoxin-producing or sterigmatocystin-producing fungi. Colonization by aflatoxinproducing or sterigmatocystin-producing fungi, such as Aspergillus spp., leads to contamination of food and feed crops by aflatoxin/sterigmatocystin. In addition, the invention is drawn to novel genetically enhanced crops containing the "anti-fungus aflatoxin or sterigmatocystin" gene which masks the detrimental effects caused by aflatoxin and sterigmatocystin. According to the invention, a mycotoxin-inhibiting agent within the lipoxygenase pathway is transferred by genetic engineering techniques to crops susceptible to the mycotoxin. In particular, the invention is drawn to the transfer of an inhibiting agent of aflatoxin or sterigmatocystin to such aflatoxin/sterigmatocystin susceptible crops as corn, peanuts, treenuts, cottonseed, etc. Alternatively, the genes encoding lipoxygenase may be modified in-situ to render a product which masks the detrimental effects caused by aflatoxin and sterigmatocystin. Still, the invention is drawn to a method of blocking the transcription of the 9hydroperoxy producing lipoxygenase genes by anti-sense genes. Still further, the invention is drawn to the creation of an "anti-Aspergillus aflatoxin or sterigmatocystin" gene (e.g. by altering lipoxygenase pathway enzyme production) and its incorporation into aflatoxin/sterigmatocystin susceptible crops.

Non-aflatoxigenic aspergillus parasiticus strains and their use in controlling aflatoxin contamination Inventor(s): Blankenship; Paul D. (Preston, GA), Cole; Richard J. (Albany, GA), Dorner; Joe W. (Albany, GA) Assignee(s): The United States of America AS Represented by the Secretary of (washington, Dc) Patent Number: 5,292,661 Date filed: August 7, 1991 Abstract: A process for biologically controlling the preharvest accumulation of aflatoxin in soil-borne crops. Non-aflatoxigenic strains of Aspergillus parasiticus having all of the relevant identifying characteristics of NRRL 18786 and NRRL 18991 are shown to inhibit aflatoxin production by native toxigenic strains of Aspergillus flavus or Aspergillus parasiticus in the soil environment. Excerpt(s): This invention relates to a method for the preharvest control of aflatoxin in crops. This is accomplished by inoculating either the crop or the soil in which it is grown with non-aflatoxigenic strains of Aspergillus parasiticus (A. parasiticus), deposited and designated as NRRL 18786 and NRRL 18991. Aflatoxins are potent hepatotoxic, carcinogenic compounds produced by fungi, particularly Aspergillus flavus (A. flavus) and A. parasiticus [Cast, (1989) Mycotoxins: economic and health risks. Report 116. Council for Agricultural Science and Technology). When these fungi invade and grow in agricultural commodities such as peanuts, corn, and cottonseed, the resulting contamination with the aflatoxins often makes the commodity unfit for consumption. They are a serious threat to humans and animals [Cast, Counc. Agric. Sci. Technol. Rep., Vol. 80, (1979), Ames, IA., 56 pp.]. The four naturally-occurring aflatoxins are designated B.sub.1,B.sub.2,G.sub.1, and G.sub.2 and will hereafter be collectively referred to as aflatoxin. The United States peanut industry has identified aflatoxin contamination of peanuts as the number one problem for which a solution is needed [Consensus Report of the National Peanut Council Quality Task Force (1987) National Peanut Council].

Non-toxigenic strain of Aspergillus oryzae and Aspergillus sojae for biocontrol of toxigenic fungi Inventor(s): Cole; Richard J. (Albany, GA), Dorner; Joe W. (Albany, GA), Horn; Bruce W. (Albany, GA) Assignee(s): The United States of America, AS Represented by the Secretary of (washington, Dc) Patent Number: 6,027,724 Date filed: July 6, 1998 Abstract: Non-toxigenic strains of Aspergillus such as from the species Aspirgillus oryzae and Aspergillus sojae are useful fungal biocontrol agents for preventing toxin contamination in agricultural commodities, especially those for human consumption such as peanuts and corn. These strains do not produce aflatoxin, any bis-furan ringcontaining intermediates of the aflatoxin biosynthetic pathway and cyclopiazonic acid. They are also useful for controlling toxin damage to crops such as cotton. The strains

include Aspergillus strains NRRL 21368, NRRL 21369, NRRL 21882, NRRL 30038, NRRL 30039 and mixtures thereof. Excerpt(s): The present invention relates to novel non-toxigenic strains of Aspergillus including Aspergillus flavus (A. flavus), Aspergillus parasiticus (A. parasiticus), Aspergillus oryzae (A. oryzae), and Aspergillus sojae (A. sojae); agricultural compositions containing non-toxigenic strains of Aspergillus flavus (A. flavus), Aspergillus parasiticus (A. parasiticus), Aspergillus oryzae (A. oryzae), and Aspergillus sojae (A. sojae) on agriculturally acceptable carriers; and to methods for the control of toxin contamination in agricultural commodities using non-toxigenic strains of A. flavus, A. parasiticus, A. oryzae, and A. sojae. Aflatoxins are potent hepatotoxic, carcinogenic compounds produced by A. flavus Link:Fr. and A. parasiticus Speare (CAST, In: Mycotoxins: Economic and Health Risks. Report 116, 99 pp., Council for Agricultural Science and Technology, 137 Lynn Avenue, Ames, IA 50010). Cyclopiazonic acid (CPA) is another potent mycotoxin that is produced by A. flavus, but not by A. parasiticus. When these fungi invade and grow in commodities such as peanuts, corn, cottonseed, and tree nuts, the resulting contamination with the aflatoxins and CPA often makes the commodity unfit for consumption. The United States peanut industry has identified aflatoxin contamination of peanuts as the number one problem for which a solution is needed (Consensus Report of the National Peanut Council Quality Task Force, 1987, National Peanut Council, Alexandria, Va. 22314). Because peanuts are used primarily for food, strict regulatory limits for the amount of aflatoxin allowable in finished peanut products have been established. Although the United States Food and Drug Administration has an action level of 20 ppb of total aflatoxins in food products, international tolerances for aflatoxin are much lower, typically in the range of 0-4 ppb, and are important because U.S. companies compete internationally in the market to export peanuts and peanut products. For this reason the United States peanut industry has a goal to ensure the delivery of aflatoxin-free peanut products by the year 2000. Although aflatoxin contamination of peanuts can occur during postharvest curing and storage, the most significant contamination usually occurs prior to harvest during periods of late-season drought stress as peanuts are maturing. The only known method for controlling preharvest aflatoxin contamination in peanuts is irrigation, an option that is unavailable to the majority of peanut growers. Cyclopiazonic acid is an indole-tetramic acid that was first isolated from cultures of Penicillium cyclopium Westling in 1968 (Holzapfel, Tetrahedrom, Volume 24, 2101-2119, 1968). CPA is now know to be produced by a variety of fungi including P. patulum, P. viridicatum, P. puberulum, P. crustosum, P. camemberti, A. flavus, A. versicolor and A. oryzae. In addition, CPA has been found as a natural contaminant of corn and peanuts, often occurring together with aflatoxin (Lansden and Davidson, Applied and Environmental Microbiology, Volume 45, 766-769,1983; Urano et al., Journal of AOAC International, Volume 75, 838-841, 1992). It was also implicated as the causative agent in a human intoxication involving consumption of contaminated millet (Rao and Husain, Mycopathologia, Volume 89, 177-180, 1985). With the discovery of CPA production by A. flavus, 54 isolates of A. flavus were investigated for production of CPA and aflatoxin (Gallagher et al., Mycopathologia, Volume 66, 31-36, 1978). It was found that 28 of the 54 (52%) produced CPA whereas only 18 (33%) produced aflatoxin. Regulatory limits for CPA have not been established; however, because of the co-occurrence of aflatoxin and CPA in commodities, efforts to attain biological control of aflatoxin also need to attain control of CPA.

Optical inspection of food products Inventor(s): Hill, Jr.; Ralph H. (San Antonio, TX) Assignee(s): Southwest Research Institute (san Antonio, Tx) Patent Number: 4,866,283 Date filed: August 12, 1988 Abstract: An optical inspection system for using laser-induced luminescence to detect the quality of organic materials, such as peanuts. The inspection system comprises an excitation means for illuminating a specimen to cause it to produce fluorescent radiation. The spectral representation of the fluorescence produced by the specimen is compared to a reference spectrum to obtain an indication of the physical characteristics of the specimen. In a preferred embodiment, the system identifies and removes peanuts contaminated with aflatoxin from a stream of peanuts by determining fluorescence at a predetermined wavelength. Excerpt(s): The present invention relates generally to the field of optical inspection of materials. More specifically, the present invention provides a method and apparatus for utilizing laser-induced fluorescence techniques to determine the quality of organic materials, such as foods. The laser-induced fluorescence techniques of the present invention can be used to detect the existence of contaminants in a stream of materials containing desired food products, such as peanuts. A common method of sorting food products is based on colorimetry. Food and biological samples have rather different light scattering properties than simple solids. The detection of slight variations in color, either by visual or by optical/electrical methods, can thus be used to sort the food products. One of the primary difficulties with such methods, however, is the inability to detect slight variations in color which represent different grades of the material or which represent undesired material. For example, in the case of food products such as peanuts, sorting systems which are based on colorimetry techniques often are not able to differentiate between a desired peanut and a rock or stem which may have the approximate color and size as a desired peanut. In addition to the basic problem of differentiating between a desired peanut and a contaminant, such as a rock or stem, it is important to be able to locate and remove contaminated peanuts. One of the contaminanants which food processors fear most is aflatoxin. This pervasive material, which is produced by the Aspergillus flavus fungus when food is improperly stored, costs the food industry millions of dollars per year. Current methods for detection of aflatoxin are time consuming and cumbersome. Web site: http://www.delphion.com/details?pn=US04866283__

improved method of identifying aflatoxinogenic aspergilli using said three sets of primers. Excerpt(s): Aflatoxins are potent carcinogenic, mutagenic and teratogenic metabolites produced primarily by the fungal species of Aspergillus flavus and Aspergillus parasiticus. Foods and feeds, especially in warm climates are susceptible to invasion by aflatoxigenic Aspergillus sp. And subsequent production of Aflatoxins during preharvesting, processing, transportation or storage. Over the last few years, means for mycotoxin detection have been simplified, by the adoption of immunological methods. The level of mold infestation and identification of the governing species are important parameters which could give an indication of the quality of the material and future potential for the presence of mycotoxins. Mold counts are a part of quality control assurance for foods. This method is time consuming, labour intensive, costly requires facilities and mycological expertise and do not allow the specification of mycotoxegenic fungi.

Process of sparing poultry from the effect of toxins Inventor(s): Taylor; Gregg W. (Murrayville, GA) Assignee(s): A.h.p., Inc. (gainesville, Ga) Patent Number: 4,126,701 Date filed: July 8, 1977 Abstract: A process of feeding animals and poultry a complete feed consisting only of (i) between 0.00077 and 0.005 percent by weight, based on the weight of the feed, of gentian violet and (ii) the remainder medically inert ingredients, such inert ingredients not having a sparing effect for poultry and animals from the toxic and/or lethal effects of aflatoxin. The gentian violet has the effect of sparing animals and poultry from the toxic effects of aflatoxins in feeds. The inert ingredients include all of the inert ingredients normally in a complete or basal animal or poultry feed. Excerpt(s): This invention relates to animal and poultry feed which contains a medicinal agent that is a selective fungicidal mold inhibitor of Candida albicans. This invention also relates to the use of such feed to spare animals and poultry from the toxic effects of aflatoxins and other mycotoxins in feed. It is known that a given strain of mold may gain or lose its ability to produce toxins without known reason. Several reasons for this phenomenon have been advanced, namely, change of substrate, genetics, stage of growth, accumulation and metabolism of the toxin, and actual stability of the toxin. Facial eczema of sheep in New Zealand has been caused by Pithomyces chartarus -- the toxin caused liver damage and skin disorders. A malady in horses, cattle, and poultry has been caused by a toxin from a mold called Stachybotrys atra. A field outbreak in Georgia of mold toxicosis in swine resulted from corn left in the field -- the toxic molds were Aspergillus flavus and Penicillium rubrum. A massive outbreak of toxicity from moldy ground nut meal (peanut) occurred in England -- the toxin producing mold was a strain of Aspergillus flavus. The common name applied to the disease is "Turkey X" disease, and the poisonous material has been designated as "Aflatoxin." Aflatoxin has carcinogenic properties. Hemorrhagic disease in chicks occurred -- toxins from certain molds will cause lesions indistinguishable from field hemorrhagic disease. Bovine hyperkeratosis has been caused by Aspergillus clavatus. A toxicosis from moldy feed at Texas Agricultural Experimental Station was caused by unidentified molds. The mold

Reduction of aflatoxin content in peanuts Inventor(s): Gross; David R. (Orrville, OH), Kragt; Marvin (Orrville, OH), Valenzky, Jr.; Robert J. (Akron, OH) Assignee(s): The J. M. Smucker Company (orrville, Oh) Patent Number: 5,230,160 Date filed: August 24, 1992 Abstract: Peanuts with a moisture content of from 6% to 15% are subjected to vacuum drying and/or roasting in a chamber using microwave energy to ensure penetration of the kernel. Aflatoxin compounds are destroyed and/or driven off with the vapors exiting the vacuum chamber. Excerpt(s): This invention relates to the art of removal of aflatoxin from cereals, oil seeds and feedstuffs which are contaminated therewith and, more particularly, to an improved method for the removal of aflatoxin from cereals, oil seeds and feedstuffs. It is of course well known that aflatoxin is a specific mycotoxin produced by the action of a fungi belonging to the genus, aspergillus, on grain, seeds, kernels or nuts. Aflatoxins are a group of related, complex, hetercyclic chemical compounds. These compounds are very slightly soluble in water and in the crystalline form melt (and decompose) at temperatures in the 240.degree. C. to 280.degree. C. range. Aflatoxin contamination is particularly problematic in the peanut industry and, in addition, can affect grains such as corn and rice, other oil seeds such as cotton seed, and meals of such grains and seeds which are often used as feed for domestic animals. The growth of fungi which produce aflatoxin is favored under the same conditions which are good for growing nuts and grains. High levels of aflatoxin in foods and feeds presents a threat to humans and animals in that aflatoxins have been shown to cause cancer in laboratory animals. Accordingly, the U.S. Food & Drug Administration has set limits on the amount of aflatoxin that can be in food products, namely less than 20 ppb. The production of aflatoxin results from unfavorable conditions of harvesting and storage, namely high humidity and moisture content. Web site: http://www.delphion.com/details?pn=US05230160__

for human or animal consumption. Meat from animals fed on the poisonous peanuts is also contaminated and unfit for human consumption. Aflatoxin in ground nuts in general and the problems of detoxification have been studied. Ground nut meal has been exposed to ultraviolet radiation, but shows no change in aflatoxin level. Solvents such as acetone, benzene and chloroform have been used. Likewise, ground nut meal has been treated with sulfur dioxide. Since no treatment was completely successful, it was concluded that successful detoxification seemed to have little potentiality and emphasis should be placed on prevention of contamination.

Asher eds. 1984); Natural Pesticides from the Neem Tree and Other Tropical Plants, Proc. 3rd Int'l Neem Conf., Nairobi, 1986 (H. Schmutterer and K.R.S. Asher eds. 1987)). These extracts have generated intense academic research interest including the isolation and identification of at least sixty different chemical entities from various parts of the neem tree (P. Jones, et al., "The Chemistry of the Neem Tree," in Phytochemical Pesticides, Vol. 1 (M. Jacobson ed., CRC Press, 1988). The active ingredient of the neem and chinaberry extracts, azadirachtin, is a limonoid of the tetranortriterpenoid type. This compound has been shown to be a potent insect growth regulator and feeding deterrent (Yamasaki, R. B., et al. (1987) J. Agric. Food Chem. 35:467-471). Several synthetic analogs of azadirachtin have been prepared (Yamasaki, R. B., et al. (1987) suora); Ley, S. V., et al. (1989) Tetrahedron 45:5175) and organic synthesis of the molecule has been accomplished (Ley, S. V., et al. (1987) Tetrahedron Lett. 28:221; Brasca, M. G., et al. (1988) Tetrahedron Lett. 29:1853; Ley, S. V., et al. (1989) Tetrahedron 45:2143; Nishikimi, Y., et al. (1989) J. Org. Chem 54:3354). Due to the complexity of the azadirachtin molecule, however, the economic synthesis and

aflatoxin contamination in plants susceptible to alflatoxin-producing fungi, like Aspergillus flavus or Aspergillus parasiticus is also disclosed. Excerpt(s): The present invention relates to the control of pathogenic microorganisms, particularly pathogenic fungi and certain bacteria. The invention also relates to lipopeptides having such antipathogenic activity i.e. high antifungal particularly against the Aspergillus genus and antibacterial activity. The invention also relates to the plants which have been treated with the lipopeptides or the microorganisms that synthesize and produce the lipopeptides. The invention also relates to other aspects further described herein. An important objective of the invention is to address and to contribute to solve the aflatoxin problem that is caused by the aflatoxin-producing fungi, Aspergillus flavus and Aspergillus parasiticus. Bacillus ssp is known to produce a variety of peptide antibiotics that are antibacterial and/or antifungal. Although the peptides antibiotics are composed of amino acids, they often differed from geneencoded polypeptides in their structure and mechanism of biosynthesis. Some are geneencoded and synthesized ribosomally, but these often undergo posttranslational processing and modifications. Antibiotics produced non ribosomally are composed of 2 to 20 amino acids organized in a linear, cyclic or branched cyclic structure. Bacillus subtilis produced gene-encoded antibiotics and a variety of small antibiotic peptides with a molecular weight less than 2000 daltons, synthesized non-ribosomally. Subtilin is one gene-encoded lantibiotic peptide synthesized by B. subtilis as a prepropeptide that undergoes posttranslational processing (1). Among the antibiotics synthesized non ribosomally are two family: the lipopeptides including iturin, surfactin, fengycin, plistatin and the small hydrophilic di- and tripeptides. Iturin is a group of cyclic lipopeptides produced by Bacillus subtilis including iturin A, C, D and E (2,3), bacillomycin D, F and L (4), Bacillopeptin (5) and mycosubtlin (6). All contains a.beta.amino fatty acid linked by amide bonds to the constituent amino acid residues of the iturin group. Iturin lipopeptide share a common sequence [.beta.-hydroxy fatty acidAsx-Tyr-Asx] and show variation at the other four positions. Surfactin is also a cyclic lipopeptide containing seven residues of D- and L-amino acids and one residue of a.beta.-hydroxy fatty acid (7) with an amino acid sequence completely different from the iturin group. It is a powerful surfactant and has been described as an antifungal agent. Fengycin (8) and plipastatin (9) are lipopeptide with ten amino acid and a lipid attached to the N-terminal end of the molecule. They differed from iturin and surfactin by the presence of unusual amino acid such as ornithine and allo-threonine. Web site: http://www.delphion.com/details?pn=US06183736__ •

Aflatoxin
Excerpt(s): The present invention relates to new derivatives of a cyclodextrin/epichlorohydrin copolymer and the use of such compounds for removing aflatoxins and phytoestrogens from a sample, for detecting the presence of aflatoxins and phytoestrogens, and for quantifying aflatoxin and phytoestrogen levels. It has long been recognized that limiting the exposure of both humans and animals to toxic or carcinogenic substances in food, water, and air is critical to our survival. Of all the toxic or carcinogenic substances that can be encountered in the environment, aflatoxins are especially important, since the presence of even minute quantities of these fungal metabolites constitute a serious health hazard. Aflatoxins are polycyclic aromatic compounds that are found in foods such as grain and peanuts as a consequence of the manner in which the foods were grown, handled, or stored. A variety of aflatoxins, including B.sub.1, B.sub.2, G.sub.1, G.sub.2, M.sub.1, and M.sub.2, have been isolated and characterized. Aflatoxin B.sub.1 is the most biologically potent of these compounds, and, as well as being a potent toxin, is also a mutagen and carcinogen. Since aflatoxins endanger public health, it is a common practice to run regular tests for aflatoxins on samples of certain foodstuffs. Such tests are typically conducted by extracting samples with an appropriate solvent, and then using standard techniques such as high pressure liquid chromatography (HPLC) to detect and quantitate aflatoxins. For example, the use of HPLC for analysis of aflatoxins in peanuts is described in U.S. Pat. No. 4,285,698. Web site: http://www.delphion.com/details?pn=US05487998__ •
Use of native Aspergillus flavus strains to prevent aflatoxin contamination Inventor(s): Cotty; Peter J. (New Orleans, LA) Assignee(s): The United States of America AS Represented by the United States (washington, Dc) Patent Number: 5,171,686 Date filed: November 29, 1989 Abstract: Methods and compositions are provided for the control or prevention of aflatoxin contamination of agricultural commodities. Non-toxigenic strains of Aspergillus flavus are shown to inhibit aflatoxin production by toxigenic strains. Additionally, the non-toxigenic strains produce a factor in culture that alone inhibits aflatoxin production by toxigenic strains. Excerpt(s): This invention relates to a method for the control or prevention of aflatoxin contamination of commodities using non-toxigenic strains of Aspergillus flavus (A. flavus). Aflatoxins are toxic compounds produced by fungi, particularly A. flavus and Aspergillus parasiticus (A. parasiticus), and are potent carcinogens that frequently contaminate agricultural commodities, especially during drought conditions, and are a serious threat to humans and animals [Cast, Counc. Agric. Sci. Technol. Rep., Vol. 80, (1979), Ames, IA., 56 pp]. The United States and most other countries prohibit aflatoxin levels in foods and feeds above 0.02.mu.g/g (20 parts per billion) Schuller, et al., Proceedings of the International Symposium on Mycotoxins, 1983, pp. 111-129, Naguib, et al. (eds.), National Research Centre, Cairo. A. flavus produces aflatoxins B.sub.1 and B.sub.2 and is the primary cause of aflatoxin contamination of corn, cottonseed, and tree nuts [Diener, et al., Annu. Rev. Phytopathol., Vol. 25, (1987), pp. 249-270]. There are several instances where a plant disease problem can be prevented by forms of the organism that incites the problem. Frost injury to plants results from ice formation caused by ice nucleation-active strains of Pseudomonas syringae and Erwinia herbicola; strains of these bacteria that are not ice nucleation active can be used to competitively
Patents 149
exclude ice nucleation active strains and thereby prevent frost injury (Lindow, S.E., Appl. Environ. Microbiol., Vol. 53, pp. 2520-2527). Several viral diseases of plants are managed by infecting the plants with mild strains of the inciting viruses; through cross protection, plants infected with the mild strains are protected from infection by more severe strains [Yeh, et al., Plant Dis., Vol. 72, (1988), pp. 369-460]. Nonpathogenic strains of Fusarium oxysporum can prevent infection of celery by pathogenic strains through competitive exclusion [Schneider, R. W., Phytopathology, Vol. 74, (1984), pp. 646-653].

Patent Applications on Aflatoxin As of December 2000, U.S. patent applications are open to public viewing.9 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 aflatoxin: •
Device for the detecting of aflatoxins Inventor(s): Stroka, Jorg; (Duisburg, DE) Correspondence: Nath & Associates, Pllc; Sixth Floor; 1030 15th Street, N.W.; Washington; DC; 20005; US Patent Application Number: 20030025086 Date filed: September 18, 2002 Abstract: A compact and portable analytical instrument dedicated to aflatoxin determination under minimum electrical power conditions employs a light emitting diode (LED) as light source with a peak output wavelength of 370 nm in addition to a 418 nm cut-off filter and a photodiode with a peak sensitivity of 140 nm. Thus, the relative amount of transmitted fluorescence energy at a wavelength of greater than 418 nm incident upon the aflatoxin is separated from the excitation light of 370 nm. In addition to the LED and the photodiode, the instrument preferably comprises amplifying, digital conversion, data storage, data transfer, display and power supply means and a graphical data output. The power supply regulator is a integrated circuit. As a result, current consumption is minimised, and thus battery life and instrument accuracy is maximised. The LED is powered by a constant current regulator, which minimises errors due to fluctuations in illumination intensity. Excerpt(s): The present invention relates to a device for the detection of aflatoxins, especially for the quantification of aflatoxins on a thin layer chromatogram (TLC). Aflatoxin determination is recognised as one of the most crucial parameters in food control, particularly for the detection of aflatoxin B1. Such measurements are today generally carried out by the use of high-pressure liquid chromatography (HPLC). However in those cases where HPLC equipment is not available or appropriate, the determination by thin layer chromatography (TLC) is commonly used. Commercial TLC scanners are available for the purpose of aflatoxin determination after TLC separation of the aflatoxins. These commercially available products TLC scanners use mercury lamps with an emission wave-length of 366 nm as a light source, while the detector consists of photo-multiers. It is clear that due to the high power consumption of these components,

Aflatoxin
these scanners are unsuitable for use where no constant electrical power is available. Furthermore these TLC scanners are quite unwieldy and therefore not suitable for infield analysis. The object of the present invention is to provide a compact device for the detection of aflatoxins, which is well suited for in-field analysis. In order to overcome the abovementioned problems, the present invention proposes a device for the detection of aflatoxin, comprising a sample holder, an excitation unit and a detection unit, wherein said excitation unit comprises an light emitting diode, said light emitting diode for emitting an excitation radiation having an excitation wavelength in the ultraviolet spectrum, wherein said detection unit comprises a cut-off filter and a photodiode, said cut-off filter having a cut-off wavelength which is higher than said excitation wavelength of said light emitting diode and said photodiode having a sensitivity at a sensing wavelength which is higher than said cut-off wavelength, and wherein said sample holder, said excitation unit and said detection unit are arranged so that said excitation radiation is emitted towards a sample placed in said sample holder and that said cut-off filter and said photodiode are positioned in the direction of emission of a fluorescence radiation emitted from said sample.

Human aflatoxin B1 aldehyde reductase Inventor(s): Bandman, Olga; (Mountain View, CA), Corley, Neil C.; (Mountain View, CA), Guegler, Karl J.; (Menlo Park, CA), Shah, Purvi; (Sunnyvale, CA) Correspondence: Incyte Genomics, INC.; 3160 Porter Drive; Palo Alto; CA; 94304; US Patent Application Number: 20030013853 Date filed: May 16, 2000 Abstract: The invention provides a human aflatoxin B1 aldehyde reductase (AFB1-hAR) and polynucleotides which identify and encode AFB1-hAR. The invention also provides expression vectors, host cells, agonists, antibodies and antagonists. The invention also provides methods for treating disorders associated with expression of AFB1-hAR. Excerpt(s): This application is a divisional application of U.S. application Ser. No. 09/391,959, filed Sep. 8, 1999, which is a divisional application of U.S. application Ser. No. 09/215,087, filed Dec. 18, 1998, now U.S. Pat. No 5,981,244, which is a divisional application of U.S. application Ser. No. 08/907,674, filed Aug. 8, 1997, now U.S. Pat. No 5,919,685. This invention relates to nucleic acid and amino acid sequences of a human aflatoxin B1 aldehyde reductase and to the use of these sequences in the diagnosis, prevention, and treatment of gastrointestinal and neoplastic disorders. Aflatoxin B1 (AFB1) is a potent environmental carcinogen produced by the common molds Aspergillus flavus, A. parasiticus, and A. nominus. Human exposure results principally from the ingestion of stored foodstuffs contaminated with these molds. Carcinogenicity is associated with the conversion of AFB1 to its 8,9-oxide by the hepatic cytochrome P450-dependent monooxygenase system. Ingestion of food contaminated with fungal aflatoxins is believed to contribute to the high incidence of hepatoma and chronic liver disease in subtropical regions.

Radioimmunoassay testing kit for detecting aflatoxin-albumin adduct Inventor(s): Huang, Henton; (Tau Yen, TW), Lee, Te-Wei; (Taipei, TW), Ting, Gann; (Taipei, TW), Wang, Mei-Hui; (Hsin Chu, TW), Wu, Chang-Yi; (Taipei, TW) Correspondence: Rosenberg, Klein & Lee; Suite 105; 3444 Ellicott Center Drive; Ellicott City; MD; 21043; US Patent Application Number: 20020115125 Date filed: January 10, 2002 Abstract: The invention discloses one radioimmunoassay testing kit and method for detecting aflatoxin-albumin adducts. The radioimmunoassay testing kit combining with competitive inhibition radioimmunometric assay, could be used to quantitate the aflatoxin-albumin adducts in serum. The invention also discloses their clinical uses in rapid mass detection of the doses of aflatoxin exposure, which is one of risk factors of liver cancer. Excerpt(s): The present invention relates to a radioimmunoassay testing kit and a method, which is used to quantitate the aflatoxin-albumin adduct. In particular the present invention relates to routine uses in serum. The present invention also relates to a method to determine if there is aflatoxin exposure or not. The normal cutoff value is also discloses. Aflatoxins are toxic metabolites produced by the fungal species Aspergillus flavus and Aspergillus parasiticus. Aflatoxin B1 (AFB 1) is the most toxic group. Experimental normal evidence that aflatoxin is carcinogenic, especially in hepatotoxicity. Using the TD50 values for rats developed by Gold et al (Cancer Res. 1993, 53: 9-11). AFB1, which TD50-9.3.times.10.sup.-4 mg/kg per day, is 1000 times more potent a carcinogen than benzo(a)pyrene. Recently, the International Agency for Research on Cancer (IARC) reported that there is sufficient evidence to classify aflatoxin B1 and mixtures of aflatoxins as Group 1 carcinogens in humans. AFB1 requires microsomal oxidation to the reactive AFB1-8,9-epoxide (AFBO) to exert its hepatocarcinogenic effects, and the extent of covalent binding of AFBO to cellular RNA, DNA, protein or other macromolecules (IARC 1993;56:303).

Summary: Hepatocellular carcinoma (HCC, liver cancer) is the fifth most common cancer and the third most frequent cause of cancer death worldwide, with an estimated 560,000 new cases per year. There are strong etiologic (causative) associations with chronic hepatitis B virus, chronic hepatitis C virus, alcoholic cirrhosis, other causes of chronic liver disease, and dietary aflatoxin exposure. This chapter on HCC is from a comprehensive gastroenterology textbook that provides an encyclopedic discussion of virtually all the disease states encountered in a gastroenterology practice. In this chapter, the authors cover epidemiology, etiology and risk factors, pathogenesis, surveillance, differential diagnosis, diagnosis, staging, locoregional therapies, and systemic therapy. The authors conclude that the selection of an appropriate treatment strategy for patients with HCC depends on careful tumor staging and assessment of the underlying liver disease. All patients with localized HCC should be evaluated for the potentially curative therapy options of partial hepatectomy or liver transplantation. Given the lack of efficacy data, there are no proven systemic chemotherapy regimens, immunotherapy approaches, or hormonal therapies that can be recommended at this time. The chapter is illustrated with black-and-white graphs and drawings. 9 figures. 4 tables. 165 references.

Coffee Break: Tutorials for Biologists18 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.19 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.20 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/.
18 Adapted 19
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. 20 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.

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 aflatoxin 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 aflatoxin. 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 aflatoxin. 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 “aflatoxin”:
166
Aflatoxin
Fungal Infections http://www.nlm.nih.gov/medlineplus/fungalinfections.html Liver Cancer http://www.nlm.nih.gov/medlineplus/livercancer.html Molds http://www.nlm.nih.gov/medlineplus/molds.html 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 NIH Search Utility The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to aflatoxin. 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.

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

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.21
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

[NIH] Complement: A term originally used to refer to the heat-labile factor in serum that causes immune cytolysis, the lysis of antibody-coated cells, and now referring to the entire functionally related system comprising at least 20 distinct serum proteins that is the effector not only of immune cytolysis but also of other biologic functions. Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors. [EU]
