Evaluation of the treatments on the proliferation and the cytotoxicity of HEK293 cells by MTT assay and LDH assay. (A) Effects of BER (1 μM, 5 μM,10 μM, and 20 μM) on the proliferation of HEK293 for 48 hours of incubation, P > 0.05 compared with vehicle-treated group (n = 5). (B) Effects of BER (5 μM) on the proliferation of HEK293 for 8, 24, 48, and 72 hours of incubation, P > 0.05 compared with vehicle-treated group (n = 5). (C). Effects of BER (5 μM), U0126 (0.5 μM), and U0126 with BER (0.5 μM+5 μM) on the proliferation of HEK293 cells for 48 hours of incubation, P > 0.05 compared with vehicle-treated group (n = 5). (D) Effects of BER (1 μM, 5 μM, 10 μM, and 20 μM) on the cytotoxicity of HEK293 for 48 hours of incubation, *P < 0.05 when compared with vehicle-treated group (n = 5). (E) Effects of BER (5 μM) on the cytotoxicity of HEK293 for 8, 24, 48, and 72 hours of incubation, *P < 0.05 when compared with vehicle-treated group (n = 5). (F). Effects of BER (5 μM), U0126 (0.5 μM), and U0126 with BER (0.5 μM+5 μM) on the cytotoxicity of HEK293 cell for 48 hours of incubation, *P < 0.05 when compared with vehicle-treated group (n = 5).
