NIDA
Recently, scientists have developed a more sophisticated understanding of the ways in which genetics influences a person's health. The complement of genes a person inherits at birth is, of course, essential. But all genes are not created equal; only some genes are "expressed"—that is, actively participate in protein production. Today, a new field of scientific inquiry, called epigenetics, investigates the cellular mechanisms that control gene expression and its impacts on health and behavior.
Epigenetic processes allow experience to influence cellular processes. For example, epigenetic alterations that accumulate during a person's lifetime can contribute to aging, the development of cancer, obesity, and other health conditions.
National Institutes of Health (NIH) Director Dr. Elias Zerhouni has charged NIDA with a key role in developing a program within the NIH Roadmap Initiative on epigenomics—the analysis of epigenetic changes across a species' entire genetic blueprint. This agency-wide effort aims to provide researchers with standard tools and technologies to develop comprehensive epigenome maps that potentially will point the way to more effective responses to a wide range of health problems.
