Induction of cell toxicity and HO-1 expression. (A) The effect of AqPM and OE on cell viability. BEAS-2B cells were exposed to OE at indicated concentrations for 16 h. (B) Induction of HO-1 by OE. Cells were treated with OE at indicated concentrations for 6 h. Cell lysate from RAW 264.7 cells exposed to DEP for 6 h was used for comparison. (C) Effect of NAC on OE-induced HO-1 expression. Cells were pre-incubated with 5 mM of NAC for 2 h before the addition of OE. Values represent means ± SEM, n = 3. *p < 0.05 compared to the respective control.
