Fig. 7. Effects of EGCG on key proteins involved in cell proliferation, oxidative stress and inflammation at PD 45 of WI-38 cells. The p53 (A), (p)Rb (B), E2F2 (C), SOD1 (D), SOD2 (E), IL-32 (F) and TNF-α (G) protein levels were determined by western blot method at PD 45 of WI-38 fibroblasts. The experiments were repeated 3 times. Data are presented as means ± SD (n = 3). *P < 0.05 compared with the control group.
