Curcumin activated JNK signaling pathway in BGC-823 cells. The amounts of curcumin (0 or 20 µM) treated BGC-823 for 24 h with or without NAC (400 µM). Then Western blot was used to assess the expression of antibodies. (A) p-ASK1, p-MKK4, p-JNK, total ASK1, total MKK4 and total JNK were analyzed via Western blot; (B) The expressions of p-ASK1, p-MKK4, p-JNK, total ASK1, total MKK4 and total JNK protein were quantitative. Control group (0 µM) level was represented as “1.0”. The value was expressed as means ± S.D. of three independent experiments. ** p < 0.01 compared with the control (0 µM) group; # p < 0.05, ## p < 0.05 curcumin-treated (20 µM) group.
