Figure 6. HLEC viability assay with or without Aβ intervention under oxidative stress. A: Inverted microscope investigation of cell morphology with or without β-amyloid (Aβ) 1–40 pretreatment under oxidative stress. B: Human lens epithelial cell (HLEC) viability assay with or without Aβ 1–42 pretreatment under oxidative stress. C: HLEC viability assay with or without Aβ 1–40 pretreatment under oxidative stress. The concentration of H₂O₂ was 200 μM. Aβ concentrations were 0.2 nM to 10 nM as listed in (B) and (C). The data are the means ± standard deviation (SD). In each group, three independent tests were performed. *p<0.05, **p<0.01, ***p<0.001 comparing the Aβ intervention groups with the vehicle control group, with one-way ANOVA and least significant difference (LSD) tests.
