This detailed volume focuses on population epigenetics, which is of increasing interest to policy makers searching for explanations for complex epidemiological observations and conceptual models on which to base interventions. With a concentration on DNA methylation, the emphasis is on the most commonly studied epigenetic phenomenon that is most amenable to further study. Written for the highly successful series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory prools, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, aims to aid population researchers in exploiting the latest insights into epigenetics to improve our understanding of the factors that influence human health and longevity.
