Epigenetics & Aging: DNA Breakage & Repair Effects

Harvard Medical School – A 13-year international study in mice demonstrates that loss of epigenetic information, which influences how DNA is organized and regulated, can drive aging independently of changes to the genetic code itself.

It also shows that restoring the integrity of the epigenome reverses age-related symptoms.
