Effects of specific signaling pathway inhibitors on HMGB1-induced proliferation of RASMCs. The primary RASMCs were incubated for 1 h with or without the protein kinase inhibitors BAY11-7082 (10 µM), U0126 (10 µM), SB203580 (10 µM) or SP600125 (50 µM) before stimulation with HMGB1 (1,000 ng/ml) for 48 h. A. The cell proliferation was evaluated by a CCK-8 assay. B. The PCNA protein expression was determined by western blot and GAPDH was used as the internal control. *: P < 0.05 vs. unstimulated cells; #: P < 0.05 vs. the RASMCs treated with HMGB1. Data are expressed as mean ± SEM from four independent experiments.
