Pharmacoepigenetics, Second Edition, Volume Ten in the Translational Epigenetics series, is a comprehensive reference on the role of epigenetics and epigenomics in drug discovery and development. Here, leading international researchers from across academia, clinical settings, and the pharmaceutical industry discuss the influence of epigenetics and epigenomics in human pathology, epigenetic biomarkers for disease prediction, diagnosis, and treatment, current epigenetic drugs, and the application of epigenetic procedures in drug development. Throughout the book, chapter authors offer a balanced and objective discussion of the future of pharmacoepigenetics and its crucial contribution to the growth of precision and personalized medicine. This new edition has been fully revised to address recent advances in epigenetics, from new natural and synthetic compounds with epigenetic effects to the role of epigenetics in the pathogenesis of a growing number of complex diseases, including further cancers, cardiovascular disorders, and brain disorders. Newly identified molecular components in the functional architecture of the epigenetic machinery, as well as practical and relevant pharmacoepigenetics topics related to COVID-19 and other world health challenges are also discussed.
