Figure 5. Effects of polydatin on tumor growth in the nude mice inoculated with HepG2 cell lines. A, tumor volume; B, body weight; C, caspase-3 activity from the resected tumor tissues; D, cell apoptosis and cell proliferation detected by TUNEL assay and Ki-67 immunostaining in the resected tumor tissues. All experiments were repeated 6 times. Data are reported as means±SD. *P<0.05 compared to control group (two-way ANOVA for tumor volume, one-way ANOVA for caspase-3 activity).
