Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated.
An epigenome-wide association study found more than a dozen methylation changes in placental DNA that correlated with expectant mothers’ self-reports of depression and stress during their pregnancy.
After initially discovering that DNA methylation represses transcription, Howard Cedar continues to explore how the epigenetic mark regulates gene expression.

Repairing damaged DNA appears to drive aging by causing the loss of epigenetic information, but restoring that information reverses such effects, a study finds.
