This book describes cutting-edge molecular technologies to unravel epigenetic changes, the use of in vivo and in vitro models, as well as the potential use of toxicological epigenetics in regulatory environments. An international team of experts considers the interplay between epigenetics and toxicology in a number of areas, including environmental, nutritional, pharmacological, and computational toxicology, nanomaterials, proteomics and metabolomics, and cancer research. This book offers essential insights into the current trends and future directions of research in this rapidly expanding field for investigators, toxicologists, risk assessors and regulators.
