Objective To explore the mechanism of tmor necrosis factor related apoptosis inducing ligand (TRAIL)-induced apoptosis in colon carcinoma cells. Methods Apoptosis, changes of mitochondrial membrane potential, cardiolipin and generation of ROS, activity of Caspase-3, in colon carcinoma cells with treatment of 500 μg/L TRAIL + /-Z-VAD. fmk, were detected by means of flowcytornetry, ELISA and flurometer methods at different time points (0,2,4,6 and 24 h). Results TRAIL could induce apoptosis in colon carcinoma...
