Fig. 5. The effect of EC on the expression of the cell cycle associated genes in HepG2 cells. Cells were treated with the various concentrations EC for 24 h. The mRNA levels of p53, p21, p27, cyclin E, and CDK 2 were determined by RT-qPCR. β-tubulin was used as the internal controls for the RT-PCR assays. Data are expressed as the mean ± SD of three experiments (*p < 0.05, **p < 0.01, vs. 0 mM).
