Available in PDF, EPUB and Kindle. Book excerpt: The study of interactions between genes and environmental exposures ha s expanded considerably in recent years. Highly penetrant genes that a re involved in familial cancer have been identified, but are likely to account for a relatively small proportion of total cancers. Other pre disposing genes have low penetrance, resulting in a moderate increase in the risk of specific cancers, but are widespread in the general pop ulation. This is the case for so-called metabolic polymorphisms. Scien tific interest in metabolic polymorphisms is based on the possibility of identifying subgroups of the population which are at elevated risk of developing environmentally-induced cancer. However, such studies ra ise a series of problems that are methodological - related to the stud y design and analysis - and ethical - related to the practical use tha t can be made of genetic information. This volume deals thoroughly wit h such problems.

Download or read book Genetic Polymorphism and cancer susceptibility written by Aga Syed Sameer and published by Springer Nature. This book was released on 2021-04-22 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the role of genetic polymorphism in susceptibility to cancers. The book explores the understanding of differences between the genetic polymorphisms and mutations.It reviews the mechanisms underlying the effect of polymorphism in genes encoding proteins that play an essential role in metabolism, signal transduction, cell cycle, and DNA repair mechanisms. Further, it investigates various techniques that are used for analyzing the genetic polymorphisms. The book contains many chapters which summarize the importance of genetic information obtained from polymorphism-based pharmaco-genetic tests to predict better drug response and life-threatening adverse reactions to chemotherapeutic agents, help in understanding of the impact of SNPs on gene function, and gives overview of the different SNP databases for examination. This book, therefore, serves as an essential guidebook for independent researchers as well as institutions working in this specialised field.
Download or read book Genetic Susceptibility to Cancer written by Seymour Garte and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite recent progress in many areas of treatment and control, cancer remains a frightening threat to everyone. While scientists have known for decades that the majority of human cancers are caused by environmental agents such as radiation and the chemicals in cigarette smoke, not everyone who smokes gets lung cancer. Furthermore, many people who assiduously avoid all possible risk from smoking, diet, and pollution still succumb to some form of cancer later in life. Does this mean that there is an element of blind chance in the underlying mechanisms of human carcinogenesis? To what extent do genetic influences play a role in determining the cancer risk of individuals? A number of `cancer families', in which several closely related individuals have suffered from various specific forms of cancer, have been studied by genetic epidemiologists. However, for the majority of cancer cases, little or no discernible genetic influence or family history is found. Recent research has discovered that for many of these `sporadic' (non-familial) cancer cases, defects or aberrations in certain metabolic genes not previously associated with genetic cancer risk may contribute to either causing the disease or at least increasing the chances of developing cancer. It is therefore possible that much of what has previously passed for `bad luck' may turn out to be a new type of `bad genes'. Genetic Susceptibility to Cancer explains that this new idea of `bad genes' may contain an unexpected positive side. The carcinogenic effects of these metabolic genes, unlike those of the oncogenes and tumor suppressor genes that are responsible for the inherited cancer syndromes, can potentially be overcome or nullified. Genetic Susceptibility to Cancer will provide a valuable reference for health professionals, researchers, clinicians and biomedical scientists who are interested in the current thinking in this critically important area of cancer management.

Download or read book Genetic Polymorphisms in AH Receptor and Cytochrome P450 Drug metabolizing Enzymes in Relation to Estradiol Metabolism and Breast Cancer Susceptibility written by Maria Shuk Mun Lam and published by . This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioactivation of environmental procarcinogens and prolonged exposure to 17ß-estradiol and catechol estrogens have been implicated in the etiology of mammary carcinogenesis. Endogenous 17ß-estradiol is oxidized to catechol estrogens by cytochrome P450 CYP1A2 and CYP1B1 enzymes which are transcriptionally regulated by the AH receptor. These enzymes are also involved in the bioactivation of numerous environmental procarcinogens such as benzo['a']pyrene. Consequently, those genetic polymorphisms in 'CYP1A2, CYP1B1' and 'AHR' that result in changes of enzyme or receptor function may affect 17ß-estradiol clearance and metabolic activation of procarcinogens. I genotyped two populations for a total of 7 polymorphisms in the 'AHR, CYP1A2' and ' CYP1B1' genes to examine whether these gene polymorphisms modify estrogen metabolism (Project 1) and breast cancer susceptibility (Project 2). Data of our estrogen metabolism study (Project 1) suggest that the 'AHR ' 554 polymorphism is related to alterations in 17ß-estradiol metabolism. Results of our Quebec French Canadian breast cancer case-control study (Project 2) indicate that the 'AHR' 554, 'CYP1A2*1F, CYP1B1*3' and 'CYP1B1*4' polymorphisms may modify breast cancer susceptibility.
Download or read book Effect of Genetic Polymorphisms of Metabolic Enzymes on Benzidine induced Bladder Cancer in Chinese Workers written by Tania Carreón Valencia and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Association was observed for the slow NAT2 genotype (bladder cancer OR=0.3, 95% CI 0.11-0.99). NAT2 phenotype results were consistent with NAT2 genotype data. The risk of bladder cancer for the GSTM1-null genotype was 1.1 (95% CI 0.58-2.26). Individuals carrying the rapid NAT1 allele showed a higher but not statistically significant risk of bladder cancer (OR=2.3, 95% CI 0.8-7.1). The GSTT1 null polymorphism showed no association with bladder cancer risk; frequencies of the rare alleles for CYP1A1, GSTP1 and UGT1A1 were too low for analysis. Study findings are consistent with other studies conducted in populations exposed only to benzidine. The data actually suggest decreased risk for benzidine-induced bladder cancer among NAT2 slow acetylators, although the mechanism for risk is not clearly understood. These results indicate the existence of key differences in the metabolism of mono- and diarylamines that combine with genotype to affect the individual susceptibility to bladder cancer.

This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Download or read book Mammography and Beyond written by National Research Council and published by National Academies Press. This book was released on 2001-06-04 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray mammography screening is the current mainstay for early breast cancer detection. It has been proven to detect breast cancer at an earlier stage and to reduce the number of women dying from the disease. However, it has a number of limitations. These current limitations in early breast cancer detection technology are driving a surge of new technological developments, from modifications of x-ray mammography such as computer programs that can indicate suspicious areas, to newer methods of detection such as magnetic resonance imaging (MRI) or biochemical tests on breast fluids. To explore the merits and drawbacks of these new breast cancer detection techniques, the Institute of Medicine of the National Academy of Sciences convened a committee of experts. During its year of operation, the committee examined the peer-reviewed literature, consulted with other experts in the field, and held two public workshops. In addition to identifying promising new technologies for early detection, the committee explored potential barriers that might prevent the development of new detection methods and their common usage. Such barriers could include lack of funding from agencies that support research and lack of investment in the commercial sector; complicated, inconsistent, or unpredictable federal regulations; inadequate insurance reimbursement; and limited access to or unacceptability of breast cancer detection technology for women and their doctors. Based on the findings of their study, the committee prepared a report entitled Mammography and Beyond: Developing Technology for Early Detection of Breast Cancer, which was published in the spring of 2001. This is a non-technical summary of that report.
