Fig. 7 Arsenic-triggered ARS2 expression was NF-κB, p38 MAPK and ERK dependent in HK-2 cells. Pretreatment of TMP (a), Bay117082 (Bay) (b), SB203580 (SB) (c) and UO126 (UO) (e), while not SP600125 (SP) (d), efficiently inhibited As-induced ARS2 expression. β-actin was used as loading control for total proteins. Values are mean ± SD (n = 3), (*) p < 0.05 versus Con
