Figure 1. Effect of magnolol on cell viability and apoptosis in SK-Hep1 cells. Cells were treated with 0-150 μM magnolol for 48 h. A) Evaluationof cell viability was executed by the MTT assay. B) Cell-cycle distribution and C) caspase-3 activity were investigated with flow cytometry. D)Protein levels of survivin and XIAP were evaluated with western blot analysis. *p<0.05 and **p<0.01 compared to control (0.1 % DMSO treatment).
