Inactivation of p21Sensitizes Cells to Apoptosis via an Increase of Both p14ARF and p53 Levels and an Alteration of the Bax/Bcl-2 Ratio

27 Sept 2002

Abstract excerpt

p21(WAF1) appears to be a major determinant of the cell fate in response to anticancer therapy. It was shown previously that HCT116 human colon cancer cells growing in vitro enter a stable arrest upon DNA damage, whereas cells with a defective p21(WAF1) response undergo apoptosis. Here we report that the enhanced sensitivity of HCT116/p21(-/-) cells to chemotherapeutic drug-induced apoptosis correlates with an...
