Norwogonin regulated the expression of apoptosis-related proteins in PC12 cells. Cells were incubated with norwogonin for 1 h and then exposed to hypoxia for 24 h. The expressions of Bax and Bcl-2 proteins were detected using Western blot analysis (a). In order to improve the clarity and conciseness of the presentation, the blots were cropped. Statistical analysis results of Bax (b), Bcl-2 (c) and Bax/Bcl-2 (d) from Western blot analysis. Results are expressed as means ± SD, n = 3. ^##P < 0.01 vs control group, ^*P < 0.05, ^**P < 0.01 vs hypoxia group
