The effect of rotenone and H₂O₂on cell viability. Cells were exposed to varying concentrations of rotenone (A) or H₂O₂ (C) for 24 h before viability was assessed using the MTT assay. (B, D) Representative light microscopy images of trypan blue staining demonstrating the effect of the toxins on cell viability and morphology. Scale bar = 50 μm, C = control. Data presented as mean ± SEM. ***p < 0.005, ****p < 0.001 vs control.
