Figure 7. Real-time RT-PCR analysis of A, cell cycle-regulating gene expression and B, p73, JunB, p16INK4a, FKHR, and Bim gene expression. HeLa cells were treated with 40 μg/mL MP [4-(3′,3′-dimethylallyloxy)-5-methyl-6-methoxyphthalide] for 0, 12, 24, and 36 h. Control cells were treated with 0.05% DMSO. Data are reported as means±SD of triplicate independent experiments. *P<0.05 and **P<0.01 compared with the control group (two-tailed unpaired t-test).
