Concerns about the adverse health effects of chemicals and radiation present in the environment and at workplaces have created the need for better detection systems to assess their potential to cause DNA damage in humans and other organisms across ecosystems. The Micronucleus Assay in Toxicology is the first comprehensive volume concerning the use of micronucleus assays in genetic toxicology. It succinctly explains the mechanisms by which genotoxins cause micronucleus formation and its relation to diseases. Furthermore, it describes the methods which are currently used for the analyses of micronuclei in different types of cells in human in vivo biomonitoring studies, routine in vivo tests with rodents, in vitro studies with human and mammalian cells, environmental monitoring with invertebrates and vertebrates such as molluscs, fish and, also, in plant bioassays. Moreover, this book also focuses on the use of the micronucleus technique in other research areas, including the detection of DNA damage caused by important groups of genotoxic carcinogens (heavy metals, industrial chemicals, cytotoxic drugs, pesticides, ionising radiation, etc.) as well as study designs, statistical analyses, international regulatory guidelines, and the development of automated scoring devices for this assay. This book will serve as both, a reference and a guide to students, and investigators in biomedical, biochemical and pharmaceutical sciences interested in gaining a better understanding of the biology of micronuclei and their application in measuring DNA damage caused by natural or man-made genotoxins.

Written in the highly successful Methods in Molecular Biology series format, the chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, as well as key tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Genotoxicity Assessment: Methods and Protocols seeks to aid research students and scientists working in regulatory toxicology as well as biomedical, biochemical and pharmaceutical sciences.

The mammalian in vivo micronucleus test is used for the detection of damage induced by the test substance to the chromosomes or the mitotic apparatus of erythroblasts, by analysis of erythrocytes as sampled in bone marrow and/or peripheral blood cells of animals, usually rodents (mice or rats).

The in vitro micronucleus test is a genotoxicity test for the detection of micronuclei in the cytoplasm of interphase cells. Micronuclei may originate from acentric chromosome fragments (i.e. lacking a centromere), or whole chromosomes that are ...

The evaluation of potential mutagenic activity is a critical step in the assessment of the safety of both new and pre-existing chemical types. In Genetic Toxicology: Principles and Methods, expert contributors help to satisfy the demand for education in this tremendously important area of study. The volume covers three basic areas: the scientific basis of the discipline, the methodologies of the main test assays, and the application of the methods, all aimed primarily at scientists in the safety departments of the industries working with both natural and synthetic chemicals. Written in the highly successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Intuitive and cutting-edge, Genetic Toxicology: Principles and Methods provides crucial support to both laboratory workers in providing quality information on the appropriate application of techniques and to study directors in their assay selection and protocol design in this vital field.

Genetic Toxicology is a comprehensive book covering the historical perspective of genetic toxicology; basic mechanisms of mutations and chromosomal effects; health consequences of genetic damage, including cancer and inheritable mutations; properties of physical, chemical, and biological mutagens; risk assessment of human exposure to genotoxicants; and the current position of some government regulatory agencies in the United States on the issues of genetic toxicology. The book will be a useful reference for students and researchers in toxicology, genetics, cancer biology, and medicine who are interested in the basic and applied principles of genetic toxicology. It will also benefit industrial toxicologists, products registration specialists, and government regulatory specialists with responsibility for the safety evaluation of industrial and environmental agents.
