Research Abstract

To identify the apoptosis-regulating machinery in p53-defective cancer cell would benefit the better strategy for cancer treatment. Present study revealed bim-dependent apoptotic pathway could survey to eliminate p63-downlagurated dangerous cancer cells. The harmful activation of EMT-inducing factor snail was also monitored by the concomitant cellular p63 downregulation, however, snail could provoke another pathway to evade bim-mediated apoptosis, which suggested the acquisition of higher invasiveness requires second round of evasions both from p53-dependent and p53-independent tumor surveillances.
