Stress Accompanied by Epigenetic Add-Ons, Many at “Neuropsychiatric” Loci

It has been called the “other” methylated base of DNA. Well studied in bacteria and plants, but relatively mysterious in insects and mammals, this form of epigenetic modification appears to have a role in the brain. It may even be involved in neuropsychiatric disorders.This other methylated base of DNA is N(6)-methyladenine (6mA). According to geneticists at Emory University School of Medicine, overall 6mA levels are “significantly elevated upon stress.” This finding, whi
