MMP2 and MMP9 expression in the cardiac tissues of three groups of rats fed different diets. (A) Relative mRNA expression levels of MMP2 and MMP9 in the cardiac tissues of each group were measured after 12 weeks. Data are presented as the mean ± SEM; n = 6 in each group. *P < 0.05 vs HFD group. (B) Representative immunohistochemical staining for MMP2 and MMP9. Arrows indicate positively stained cells. (C) Bar graph showing MMP2 and MMP9 positive cells. Data are presented as the mean ± SEM; n = 3 in each group. *P < 0.05 vs HFD group.
