Effect of heme oygenase-1 on PM2.5 exposure induced oxidative stress response in human melanocytes. PIG1 or PIG3V cells were pretreated with 10 µM ZnPP or 10 µM Hemin for 2 h prior to incubation with 200 µg/ml PM2.5 for 24 h. MDA contents, and SOD and GSH-Px activity in (A) PIG1 and (B) PIG3V cells. Data are presented as the mean ± SD. n=6. ^*P<0.05 vs. Ctrl; ^#P<0.05 vs. PM2.5. PM2.5, particulate matter 2.5; MDA, malondialdehyde; GSH-Px, glutathione peroxidase; SOD, superoxide dismutase; ZnPP, zinc protoporphyrin; Hemin, hemin chloride; Ctrl, control.
