The Cellular Response to the Genotoxic Insult

The Question of Threshold for Genotoxic Carcinogens
RSC
Langbeschreibung
This book considers the exposure levels at which genotoxins pose a risk and describes the cellular mechanisms used against them.
Inhaltsverzeichnis
Introduction: The rationale for thresholds for genotoxic carcinogens; Part 1. Threshold effects observed in experimental studies: Mechanisms responsible for the chromosome and gene mutations driving carcinogenesis: implications for dose-response characteristics of mutagenic carcinogens; Dose-effect relationships of DANN-reactive liver carcinogens; DNA alkylation and repair after EEMS exposure: Where do the thresholds for mutagenic/clastogenic effects arise? Part 2. Metabolic inactivation of genotoxic reactants: Enzymatic detoxification of endogenously produced mutagenic carcinogens maintaining cellular homeostasis; Phase 2 detoxifying enzymes and anti-oxygen defense mechanisms in the inactivation of genotoxic carcinogens; Part 3. DNA repair: Consequences and Repair of oxidative DNA damage; The plasticity of DNA damage response during cell differentiation: pathways and consequences; Tumor suppressor protein-mediated regulation of base excision repair in response to DNA damage; Part 4. Apoptosis: Survival and death strategies in cells exposed to genotoxin; Different modes of cell death induced by DNA damage; Transcriptional inhibition by DNA damage as a trigger of cell death; Part 5. Epigenetic mechanisms: The interplay between epigenetics and Gap junctionional intercellular communication; Index
Helmut Greim is a toxicologist and former chair of the Institute of Toxicology and Environmental Hygiene at the Technical University of Munich, Germany. His research experience is drug metabolism, toxicokinetics, mechanisms of carcinogenic agents, in vitro test systems. He has been member or chair of numerous national and international scientific committees. In 1996 he received the Arnold Lehman Award of SOT and in 2001 the Herbert Stockinger Award of the American Conference of Governmental Industrial Hygienists. At present he chairs the Scientific Committee on Health and Environmental Risks of the DG SANCO, Brussels, is member of the Scientific Committee on Occupational Exposure Limits of DG EMPLOYMENT, Luxembourg and member of the Risk Assessment Committee of the European Chemicals Agency in Helsinki, Finland. Dr. Albertini is currently Research Professor of Pathology at the University of Vermont (USA). He retired from the Department of Medicine at that University in 2000 and is now an Emeritus Professor of Medicine. He received the M.D. degree in 1963 and a Ph.D. in Medical Genetics in 1972, both from the University of Wisconsin, Madison (USA). Dr. Albertini joined the Department of Medicine at the University of Vermont that same year, becoming full Professor in 1979. He was clinically active in the areas of oncology, hematology and AIDS for many years and served as Director of the Vermont Cancer Center from 1993 to 1995. Dr. Albertini's fundamental research has been and remains in the area of mutagenesis and the relationship of somatic mutations to cancer. In the past, Dr. Albertini served as President of the Environmental Mutagen Society and as editor-in-chief of Environmental and Molecular Mutagenesis.
