TMP and NAC inhibited arsenic-induced pro-inflammatory signals: p38 MAPK activation and COX-2 up-regulation in HK-2 cells. a, b Arsenic-induced p38 MAPK activation was verified by increased levels of phospho-Thr180/Tyr182 p38 MAPK (p-p38) expression, which was inhibited by NAC or TMP pretreatment. c, d Arsenic up-regulated COX-2 protein expression, while NAC and TMP suppressed COX-2 protein up-regulation. β-Actin was used as loading control. Values are mean ± SD (n = 3), **p < 0.01 versus Con
