METHODS: Twenty-seven male C57BL/6 mice were divided randomly into 3 groups: nondibetic (ND), STZ-induced diabetic (D), and STZ-induced diabetic that were treated with .5 g. kg1. daylof FRC by oral gavage (DFRc), with 9 in each group. The protein ex- pressions of E-cadherin, a-smooth muscle actin (a-SMA), Plasminogen Activator Inhibitor-1 (PAl-l) in renal tissues were investigated by Western blot- ting. The expressions of fibronectin (FN) and o-SMA were detected by immunohistochemical method. The morphological changes of renal tissues were observed under a microscope. RESULTS: Renal tissues in the DFRC group showed a lessened degree of fibrosis. Meanwhile, the expres- sions of FN, o-SMA and PAl-lwere significantly lower in the DrRc group than those in the D group (all P〈0.05).CONCLUSION: FRC can ameliorate the DN in the C57BL/6 mice, and its mechanism may relate to in- hibition on the epithelial to mesenchymal transdif- ferentiation, endothelial-myofibroblast transition and PAl-1 expression.展开更多
