Fig. 4. Effect of sinapine on liver oxidation index and gene expression. The liver MDA (A) and SOD (B) of mice with different diets were included. The mRNA levels of genes examined by QPCR were expressed relative to that of mice fed with low-fat diet (C and D). Data are expressed as mean ± SEM (n = 10). Different letters indicate significant differences (P < 0.05) between groups; the one-way ANOVA test followed by the Tukey test. Note: LF: low-fat diet; HF: high-fat diet; RO: rapeseed oil diet; RP: rapeseed polyphenol diet.
