Researchers have found a link between the methylation state of rRNA genes in the hippocampus and suicide, reports The Scientist. People who committed suicide had highly methylated rRNA genes as compared to healthy brains, but only in the region that regulates stress hormones. The researchers, led by McGill University's Moshe Szyf, then compared the brains of suicide victims who had been abused as children to those who had not and found that the methylation patterns differed. This suggest that childhood abuse lastingly affects the brain.
