Focuses of this volume: chemical carcinogenesis, exposure to major classes of human carcinogens and their mode-of-action, the balance between metabolic activation to form biological reactive intermediates and their detoxification, and environmental agents that can promote tumor formation
appeals to graduate students, post-doctoral fellows and faculty interested in this aspect of cancer causation and research
This volume will provide a contemporary account of advances in chemical carcinogenesis. It will promote the view that it is chemical alteration of the DNA that is a route cause of many cancers. The multi-stage model of chemical carcinogenesis, exposure to major classes of human carcinogens and their mode-of-action will be a focal point. The balance between metabolic activation to form biological reactive intermediates and their detoxification, ensuing DNA-lesions and their repair will be profiled. It will describe the chemical changes that occur in DNA that result from endogenous insults including epigenetic changes that lead to gene silencing. It will describe major mechanisms of mutagenesis, affects on tumor suppressor genes and proto-oncogenes, and how cell-cycle check points can be by-passed by the "stealth-like" properties of chemical carcinogens. Environmental agents that can promote tumor formation will be discussed. The monograph will have wide appeal as a knowledge base for graduate students, post-doctoral fellows and faculty interested in this aspect of cancer causation and research.

This monograph provides a contemporary account of advances in chemical carcinogenesis. It promotes the view that it is alteration of the DNA by endogenous and exogenous carcinogens that ultimately leads to sporadic mutations which are a root cause of many human cancers. It deals with the metabolic activation of common classes of chemical carcinogens (tobacco carcinogens, heterocyclic amines, polycyclic aromatic hydrocarbons) and their detoxication. It describes the DNA-adducts that ensue and their repair mechanisms. It covers advances in structural-biology that provide a glimpse of both the DNA-repair process and the by-pass of DNA-lesions and how this informs the mutational code. It also deals with the concepts of chemoprevention and biomarkers for biomonitoring human exposure. Many contemporary texts on the biology of cancer now focus almost exclusively on the molecular and cell biology of the disease and do not cover the initiating (DNA damaging events) of chemical carcinogenesis in depth. It is with this perceived gap-in knowledge that world experts in their particular fields have contributed to this monograph. This monograph will be an important reference re-source for students in training, postdoctoral scientists, and senior scientists knowledgeable in the field.
This volume will provide a contemporary account of advances in chemical carcinogenesis. It will describe major mechanisms of mutagenesis, affects on tumor suppressor genes and proto-oncogenes, and how cell-cycle check points can be by-passed by the "stealth-like" properties of chemical carcinogens.
Presenting the current advances in chemical carcinogenesis, this volume promotes the view that the chemical alteration of DNA is a route cause of many cancers. Topics include the multi-stage model of chemical carcinogenesis, exposure to major classes of human carcinogens and their mode-of-action.
