Expression of apoptosis-related proteins in the A549 cells after treatment with yatein (5 μM) for 12, 24, and 48 h. The bands were analyzed using the ImageJ software and normalized to β-actin. All data presented are representatives of three independent experiments with similar results. The results represent the mean ± SD (n = 3). Asterisk indicates a significant difference compared with the control group (p < 0.05). p values were calculated by Student’s t test
