DNA damage, chromatin, and transcription: the trinity of aging

Curr Opin Cell Biol. 2012 Dec;24(6):724-30. doi: 10.1016/j.ceb.2012.07.005. Epub 2012 Aug 17.

Abstract

Aging brings about numerous cellular defects. Amongst the most prominent are elevated levels of persistent DNA damage, changes to chromatin structure and epigenetic modifications, and alterations of global transcription programs. These are not independent events and recent work begins to shed light on the intricate interplay between these aging-related defects.
