Evaluation of the treatments on the expression of the activation of ERK1/2 pathway by Western blot. BER (1 μM, 5 μM, 10 μM, and 20 μM) can significantly increase phosphorylation-ERK1/2 for 48 hours of incubation, *P < 0.05 compared with vehicle-treated group, #P < 0.01 compared with vehicle-treated group (n = 3). (B) BER (5 μM) can increase phosphorylation-ERK1/2 from 8 to 72 hours of incubation, *P < 0.05 compared with vehicle group, #P < 0.01 compared with vehicle-treated group (n = 3). (C) U0126 (0.5 μM) can completely abolish the activation of BER on ERK1/2, *P < 0.05 compared with the vehicle-treated group, #P < 0.01 compared with vehicle-treated group (n = 3).
