Effect of APS on the H2O2-induced mitochondrial membrane potential and total antioxidant capacity impairment in RAECs. (a) The mitochondrial membrane potential (MMP, Δψm) was observed using JC-1 staining. The red/green fluorescence intensity ratio was used to quantify the MMP. Magnification: 200×. Scale bar = 100 μm. (b) Summary ΔψM data are shown. (c) Intracellular total antioxidant capacity was determined with a T-AOC assay. Values are the means ± S.D. (n = 6). ** p < 0.01 vs. control (Con) group; # p < 0.05, ## p < 0.01 vs. H2O2 group
