From: Vitamin E succinate inhibits survivin and induces apoptosis in pancreatic cancer cells
VES induces apoptosis in PANC-1 cells. a Apoptosis was determined by the flow cytometry of cells treated with 80 μM VES at the indicated time periods (4, 8, 24, 30, and 48 h). The percentage of cells containing sub-G1 DNA content was used as an index of apoptosis. P < 0.05 was considered significant. Asterisk denotes P < 0.01 as compared to control. b PARP cleavage was determined by immunoblotting
