TGFB1 and hyperlipidemia: Tofurther explore the molecular mechanism of cardiac fibrosis in hyperlipidemia mice,using western blot analysis and immunohistochemical staining, we examined theprotein expressions of TGF-β which are intricately linked with theprofibrotic effects of mast cells, and the Wnt/β-catenin pathway that isessential for the fibrosis induced by TGF-β.
