Replicative senescence and senescence-like state induced in cancer-derived cells

Eun Seong Hwang. Mech Ageing Dev. 2002 Nov.

Abstract

Studies on the replicative senescence and premature senescence induced by various stresses in normal somatic cells have provided important clues on the role of telomere shortening and mechanisms involved in aging processes and carcinogenesis. Recent work revealed that cancer cells also are induced to undergo replicative senescence state via telomere shortening as well as to enter a senescence-like state by the activation of cell cycle inhibitory pathways. Although less relevant in terms of aging physiology, studies on these phenomena in cancer cells have yielded important information on telomerase regulation and the roles of tumor suppressors in senescence and immortalization, and are expected to generate valuable anti-cancer strategies. Several features of the phenotypes specific for the senescent and senescence-like states induced in cancer cells are discussed.
