Figure 5. OPE suppresses A20 cell proliferation via inactivation of EGFR. (A) Western blot analysis of the expression and phosphorylation of EGFR in A20 cells. (B) Western blot analysis of the expression and phosphorylation of EGFR in A20 cell-derived tumors. (C) The viability of A20 cells after treatment with OPE (50 μg/mL) together with or without EGF (50 ng/mL). (D) The apoptosis of A20 cells after treatment with OPE (50 μg/mL) together with or without EGF (50 ng/mL). (E) Flow cytometry analysis of apoptosis of A20 cells treatment with OPE (μg/mL) together with or without EGF (50 ng/mL) for 48 h. Data are presented as means ± SD of at least three independent experiments. (*p < 0.05; ***p < 0.001, compared to the untreated control).
