Role of NF-κB, p38, ERK1/2 and JNK in the induction of IL-1β, IL-6 and COX-2 by SAA1 in human amnion fibroblasts. (A and B) Effect of NF-κB inhibitor JSH-23 (10 µM) on SAA1 (10 ng/mL, 24 hours)-induced changes in IL-1β, IL-6 mRNA (A, n = 4), COX-2 mRNA and protein (B, n = 3) in human amnion fibroblasts. (C and D) The effect of p38 inhibitor SB203580 (10 µM) on SAA1 (10 ng/mL, 24 hours)-induced IL-1β, IL-6 mRNA (C, n = 4), COX-2 mRNA and protein (D, n = 3) in human amnion fibroblasts. (E and F) Effect of ERK1/2 inhibitor PD98059 (20 µM) on SAA1 (10 ng/mL, 24 hours)-induced IL-1β, IL-6 mRNA (E, n = 4), COX-2 mRNA and protein (F, n = 3) in human amnion fibroblasts. (G and H) Effect of JNK inhibitor SP600125 (20 µM) on SAA1 (10 ng/mL, 24 hours)-induced IL-1β, IL-6 mRNA (G n = 4), COX-2 mRNA and protein (H) n = 3) in human amnion fibroblasts. Top panels of (B,D,F and H) are the representative immunoblots. Data are the means ± SEM. Statistical analysis was performed with one-way ANOVA test. **P < 0.01, ***P < 0.001 vs. control (0), ^#P < 0.05, ^##P < 0.01, ^###P < 0.001 vs. SAA1.
