SIRT6 protein could protect against age-related breakdown in chromatin, possibly help reverse aging

Researchers at Bar-Ilan University have successfully restored youthful patterns of DNA organization in the livers of old mice, reversing key molecular features associated with aging. The study, published in Nature Communications, identifies the protein SIRT6 as a powerful protector against age-related breakdown in chromatin, the complex system that packages DNA and controls how genes are switched on and off.
