Hinokitiol’s effect on cell-apoptosis-related protein expression in endometrial cancer cells. Ishikawa (A,J), HEC-1A (B,K), and KLE (C,L) cells were treated with hinokitiol (0, 1, 5, 10, 25, and 50 µM) for 48 h, and the protein expression of PARP (D–F), Bax, Bcl-2 (G–I), and caspase-3 (M–O) was assayed with a Western blotting analysis. The differences in the target proteins were analyzed with a Sigma Plot, and the data are expressed as the mean ± SD of three independent experiments; * p < 0.05 compared to the control group.
