Effect of BHMC and curcumin on Keap1 expression after treatment for (A) 18 h and (B) 24 h in HepG2 cells. The relative fluorescence intensity was measure using Image J software. Data are expressed as mean ± S.E.M. from three independent experiments. Statistical significance was determined using one-way ANOVA, followed by Dunnett’s post hoc test for multiple comparisons with the untreated control group. Significant difference at 18 and 24 h of incubation are indicated as *p < 0.05 and **p < 0.01.
