Aging impacts epigenome in human skeletal muscle

Our epigenome is a set of chemical switches that turn parts of our genome off and on at strategic times and locations. These switches are impacted by environmental factors including diet, exercise and stress. Research at the Buck Institute reveals that aging also effects the epigenome in human skeletal muscle. The study provides a method to study sarcopenia, the degenerative loss of muscle mass that begins in middle age.
