Among the different chemotherapies available, genotoxic drugs are widely used. In response to these drugs, particularly doxorubicin, tumor cells can enter into senescence. Chemotherapy-induced senescence (CIS) is a complex response. Long described as a definitive arrest of cell proliferation, we and...
As normal cells approach their proliferative limit, they arrest to undergo replicative senescence, displaying large cell size, flat morphology and activation of senescence-associated beta-galactosidase (SA-b-Gal). A subset of normal or tumor cells exposed in vitro or in vivo to chemotherapy agents s...
Treatment induced senescence (TIS) is a terminal cell cycle arrest program, increasingly recognized as a tumor suppressor mechanism complementing apoptosis in response to standard chemotherapy regimens. In particular cells with blocked apoptotic pathways rely on senescence as the only remaining fail...
