Apoptosis is an important mechanism to eliminate potentially tumorigenic cells. The tumor suppressor p53 plays a pivotal role in this process. Many tumors harbor mutant p53, but others evade its tumor-suppressive effects by altering the expression of proteins that regulate the p53 pathway. ASPP1 (apoptosis-stimulating protein of p53-1) is a key mediator of the nuclear p53 apoptotic response. Under basal conditions, ASPP1 is cytoplasmic. We report that, in response to oncogenic stress, the tum...Expand abstract
