Hardcover. Condizione: new. Hardcover. Genotoxic carcinogens can lead to DNA mutations with the potential to cause cancer. Typically, a series of mutation events are needed before malignancy occurs so a single, small exposure may not result in disease. Also, cells have an armoury of defence mechanisms which, to a degree, counter the effects of mutagens. Distinguishing the point at which exposure to a carcinogen increases mutation rates beyond the background level is challenging. In fact, there is now general agreement that, for genotoxic carcinogens, no specific threshold can be identified. However, NOAELs (No Observed Adverse Effect Levels) may be used in the process of establishing a dose-response relationship. These denote the level of exposure at which there is no significant increase in adverse effects in the exposed population when compared to an appropriate control. Such a scientifically defendable threshold allows us to propose health based exposure limits for genotoxic carcinogens. This book describes the various cellular defence mechanisms individually and explains how they are regulated. The processes covered include metabolic inactivation, epigenetic regulation, scavenging mechanisms, DNA-repair and apoptosis. It also considers dose-dependent threshold mechanisms of carcinogenesis and the rate limiting parameters. Aimed at graduate level and above, the book discusses the consequences of genotoxic evaluation and urges readers to question the idea that even low exposures present a cancer risk. This book considers the exposure levels at which genotoxins pose a risk and describes the cellular mechanisms used against them.

Buch. Condizione: Neu. Neuware - Although the cellular defence mechanisms are increasingly understood, the critical and rate limiting parameters and their dose-response to the insulting agent need to be evaluated. In this book the different cellular defence mechanisms and their regulation are described. Understanding the protective mechanisms by which the cell responds to a genotoxic impact to protect integrity of the genomes will permit the evaluation of whether the assumption of a threshold for genotoxic carcinogens at low dose exposure is justified. Besides its scientific value, this dispute is of regulatory importance since it may result in a scientifically defendable threshold concept for genotoxic carcinogens, will allow identification of a NOEL and by that to propose health based exposure limits - even for genotoxic carcinogens.…
