Figure 5. Effect of EGCG on UVA-induced JNK, ERK, and p38 phosphorylation. ARPE19 cells were preincubated with EGCG for 2 h then exposed to 20 J/cm² UVA irradiation. After further incubation, cells were collected and lysates were analyzed by western blot analysis. Each result is representative of five to seven experiments.
