The EpigenomeSeptember 16, 2013
Expert: Randy Jirtle, Ph.D.
If the genome is like a biological "hard drive," the epigenome is like a computer program that provides instructions for translating genetic information into action. Recent insights about how the epigenome affects our health are leading to a new way of thinking about environmental exposures.
Randy Jirtle, Ph.D. is a Professor of Epigenetics at the Department of Sport and Exercise Sciences, University of Bedfordshire, Bedford, UK, and a Senior Scientist at McArdle Laboratory for Cancer Research at the University of Wisconsin, Madison. Dr. Jirtle’s research interests are in epigenetics, genomic imprinting, and developmental origins of health and disease (DOHaD). He identified the first imprinted tumor suppressor gene, IGF2R, determined the evolutionary origins of genomic imprinting, and provided the first experimental evidence that DOHaD results from alterations in the epigenome. He was previously professor of radiation oncology and associate professor of pathology at Duke University.
