Both telomeric and non-telomeric DNA damage are determinants of mammalian cellular senescence

Abstract excerpt

BACKGROUND: Cellular senescence is a state reached by normal mammalian cells after a finite number of cell divisions and is characterized by morphological and physiological changes including terminal cell-cycle arrest. The limits on cell division imposed by senescence may play an important role in both organismal aging and in preventing tumorigenesis. Cellular senescence and organismal aging are both accompanied...
