Effects of MPP+, hemin, SnPPIX, DPI and ATX on cell viability. Cells were treated with different concentrations of MPP+, hemin, SnPPIX, DPI and ATX for 24 h, after which the MTT assay was performed. (A) MPP+ (0–2000 μΜ); (B) Hemin (0–40 μΜ); (C) SnPPIX and ATX (0–20 μΜ); (D) DPI (0–16 μΜ). Relative cell survival values are expressed as a percentage of the control value, *p < 0.05 vs. untreated control, **p < 0.01 vs. untreated control, # p < 0.05 vs. MPP+ (500 μΜ) treatment only, ## p < 0.01 vs. MPP+ (500 μΜ) treatment only.
