The Cellular Response to the Genotoxic Insult: The Question of Threshold for Genotoxic Carcinogens (Issues in Toxicology, Volume 13)

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.
