Available in PDF, EPUB and Kindle. Book excerpt: "The glutathione-S-transferases (GSTs) are a multigene family of enzymes that catalyze the conjugation of glutathione (GSH) with toxic endogenous and xenobiotic compounds including anticancer drugs, as part of detoxification pathways. Our laboratory previously isolated a melphalan resistant rat mammary carcinoma cell-line (MLNr MatB). The in vitro and in vivo studies demonstrated increased GST activity, especially elevated GST alpha class in MLNr cells. At the outset of my work, I examined the nature of the increased GST form in MLNr cells. I cloned the GSTA3 cDNA which is overexpressed in MLNr cells and found that it is identical to the previously described GSTA3 mRNA, suggesting that there is no additional GST alpha gene induced by melphalan. To study the role of the rat GSTA3 gene in chemotherapy resistance, and understand the mechanism of its overexpression in drug resistant tumors, I isolated the entire rGSTA3 subunit gene, including its regulatory regions, from a genomic library and characterized it. The rGSTA3 gene is approximately 15 kb in length and consists of seven exons interrupted by introns of different lengths. The functional activity of its promoter was shown by its ability to drive the expression of a CAT reporter gene in MatB cells, and its activity was greater in melphalan resistant cells. I also presented evidence that rGSTA3 subunit evolved as a duplication of the rGSTA5 subunit gene, increasing the diversification and functional benefits. In addition to drug resistance, I have been examining the implications of GST to carcinogenesis. Epidemiological studies have shown an association between Hepatitis B Virus (HBV) infection and exposure to chemical carcinogens in the incidence of hepatocellular carcinoma (HCC). The exact mechanism of these interactions is not known, but reduced GST activity could increase cellular sensitivity to chemical carcinogens. Semiquantitative RT-PCR revealed that HBV infected cells contain a significant decrease in th" --

Available in PDF, EPUB and Kindle. Book excerpt: A timely book for DNA researchers, Automated DNA Sequencing and Analysis reviews and assesses the state of the art of automated DNA sequence analysis-from the construction of clone libraries to the developmentof laboratory and community databases. It presents the methodologies and strategies of automated DNA sequence analysis in a way that allows them to be compared and contrasted. By taking a broad view of the process of automated sequence analysis, the present volume bridges the gap between the protocols supplied with instrument and reaction kits and the finalized data presented in the research literature. It will be an invaluable aid to both small laboratories that are interested in taking maximum advantageof automated sequence resources and to groups pursuing large-scale cDNA and genomic sequencing projects. The field of automation in DAN sequencing and analysis is rapidly moving, this book fulfils those needs, reviews the history of the art and provides pointers to future development.
Download or read book Oxidative Stress and Redox Regulation written by Ursula Jakob and published by Springer Science & Business Media. This book was released on 2013-03-15 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many physiological conditions such as host defense or aging and pathological conditions such as neurodegenerative diseases, and diabetes are associated with the accumulation of high levels of reactive oxygen species and reactive nitrogen species. This generates a condition called oxidative stress. Low levels of reactive oxygen species, however, which are continuously produced during aerobic metabolism, function as important signaling molecules, setting the metabolic pace of cells and regulating processes ranging from gene expression to apoptosis. For this book we would like to recruit the experts in the field of redox chemistry, bioinformatics and proteomics, redox signaling and oxidative stress biology to discuss how organisms achieve the appropriate redox balance, the mechanisms that lead to oxidative stress conditions and the physiological consequences that contribute to aging and disease.
Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . 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 Pine Wilt Disease written by Bo Guang Zhao and published by Springer Science & Business Media. This book was released on 2008-09-27 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pine forests face a global threat of pine wilt disease, which is being spread by vector beetles carrying pathogenic nematodes from dead trees to healthy ones. Among the host pines there are varying degrees of susceptibility, and nematode strains also contain a variety of virulences, both of which factors help to determine whether infected host trees will die or survive. As well, biotic and abiotic environmental factors influence the fate of infected trees. This book describes the history of the disease, pathogenic nematodes, vector beetles, the etiology and ecology of the disease, microorganisms involved, and control methods that utilize host resistance and biological control agents. Concrete, comprehensive, and the most up-to-date knowledge about this worldwide forest epidemic is presented for readers, enabling them to understand the nature and epidemic threat of pine wilt disease.

Available in PDF, EPUB and Kindle. Book excerpt: Welcome to your study of enzyme kinetics, the subject that underlies all enzymology, which in turn underlies all aspects of biochemistry. This text will give you an introduction to a wide range of topics that constitute the modern enzyme kinetics. This textbook is directed at graduate students in biochemistry, chemistry, and life sciences, for advanced courses in enzyme kinetics, enzymology, and enzyme chemistry. For this reason, the whole book is organized in a systematic and scholarly fashion. It is unlikely that the student will be expected to cover everything in the text, but in a later career she or he may find it an invaluable reference for topics that are needed in practice. The concepts, definitions and detailed algebra of enzyme kinetics are laid out in accurate detail. For that reason, this textbook can also serve as a handbook for enzyme kinetics for research workers in the field. The research worker will find it a useful source, which can be used for solving the daily experimental problems in the laboratory. The preparation of the manuscript for this book was under the constant surveillance of W. Wallace Cleland, Professor of Chemical Science at the University of Wisconsin in Madison, and one of the founders of modern enzyme kinetics. Without his help and advice, this bookwould not be possible. Several versions of the manuscript were constantly corrected and improved by Svetlana Professor of Biochemistry at the University of Novi Sad.

Download or read book Public Health Consequences of E Cigarettes written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2018-05-18 with total page 775 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of Americans use e-cigarettes. Despite their popularity, little is known about their health effects. Some suggest that e-cigarettes likely confer lower risk compared to combustible tobacco cigarettes, because they do not expose users to toxicants produced through combustion. Proponents of e-cigarette use also tout the potential benefits of e-cigarettes as devices that could help combustible tobacco cigarette smokers to quit and thereby reduce tobacco-related health risks. Others are concerned about the exposure to potentially toxic substances contained in e-cigarette emissions, especially in individuals who have never used tobacco products such as youth and young adults. Given their relatively recent introduction, there has been little time for a scientific body of evidence to develop on the health effects of e-cigarettes. Public Health Consequences of E-Cigarettes reviews and critically assesses the state of the emerging evidence about e-cigarettes and health. This report makes recommendations for the improvement of this research and highlights gaps that are a priority for future research.
