DNA Repair Defects in Stem Cell Function and Aging

Abstract excerpt

Cellular DNA is under constant challenge by exogenous and endogenous genotoxic stress, which results in both transient and accumulated DNA damage and genomic instability. All cells are equipped with DNA damage response pathways that trigger DNA repair, cell cycle arrest, and, if need be, apoptosis, to eliminate DNA damage or damaged cells. The consequences of these processes for stem cells can be profound:...
