aims to bring together a series of articles describing validated methods to elucidate specific molecular aspects of toxicology, the emphasis being on the application of molecular methods to genetic toxicology. The volume is divided into ten parts, roughly corresponding to the spectrum of biomarkers intermediate between exposure and disease outcomes as proposed in molecular epidemiology models. Subjects of these new chapters range from preparation of fluid specimens for analysis of cellular inflammatory responses to genotoxic insults to sensitive methods for proteomic analysis and aberrant DNA methylation patterns. Written in the successful series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, addresses not only the needs of molecular biologists and toxicologists, but also those of individuals interested in applying molecular methods to clinical applications, such as geneticists, pathologists, biochemists, and epidemiologists.
