Acquisition of Oxidative DNA Damage during Senescence

Abstract excerpt

As a result of time and cumulative divisions in vitro and in vivo, normal cells enter an irreversible nonproliferative state termed replicative or cellular senescence that is thought to contribute to organism aging. Both telomere shortening and cumulative oxidative damage were shown to contribute to senescence, probably acting at different degrees according to proliferation index, cell type, or environment....
