Effects of MOSE and luteolin on expressions of SOD, CAT and PPARα. Lenses were pretreated with MOSE (0.5 and 1.0 mg/mL) or luteolin (0.05 mg/ mL) for 24 h, followed by incubation with H₂O₂ (1 mM) for another 24 h, and then recovered in fresh medium for 48 h. Then, protein expressions were  determined by  western blot (a). Quantification of western blot  for SOD (b), CAT (c), and PPARα (d). Data are expressed as the mean ± SEM (n = 3); ^#P < 0.05 and ^##P < 0.01, compared with the normal control group; *P < 0.05 and **P < 0.01, compared with the H₂O₂ treatment group
