Effects of curcumin on H₂O₂-induced cell viability in HTR8/SVneo cells measured by the CCK-8 assay; (A) Cell viability of HTR8/SVneo cells treated with different concentrations of H₂O₂; (B) cell viability of HTR8/SVneo cells treated with different concentrations of curcumin; (C) cell viability of HTR8/SVneo cells pretreated with 2.5 or 5 μM curcumin against H₂O₂-induced oxidative stress. Data are presented as the mean ± SEM (n = 3) ^{a, b, c} Means with different letters are significantly different (p < 0.05).
