1 Although the primary response to Adriamycin (doxorubicin) in p53 mutant MDA-MB231 and p53 null MCF-7/E6 breast tumor cells is apoptotic cell death, the residual surviving population appears to be in a state of senescence, based on cell morphology, beta galactosidase staining, induction of p21(waf1/cip1) and down regulation of cdc2/cdk1. Doxorubicin cyclin dependent kinase 1 Homo sapiens

4 Although the primary response to Adriamycin (doxorubicin) in p53 mutant MDA-MB231 and p53 null MCF-7/E6 breast tumor cells is apoptotic cell death, the residual surviving population appears to be in a state of senescence, based on cell morphology, beta galactosidase staining, induction of p21(waf1/cip1) and down regulation of cdc2/cdk1.

5 Taken together, these studies suggest that accelerated senescence induced by Adriamycin is similar in cells with wild type p53 and in cells lacking functional p53 with regard to the upregulation of p21(waf1/cip1), down regulation of cdc2 and the involvement of reactive oxygen species. Doxorubicin cyclin dependent kinase 1 Homo sapiens
