ABSTRACT
Purpose To investigate the role of SOCS3 on diabetic renal injury. Methods Male CD-1 mice were randomly divided into four groups:control group, diabetic group, empty plasmid vector transfection group and SOCS3 plasmid transfection group. The diabet-ic mice were induced by intraperitoneal injection of STZ at a dose of 150 mg/kg body weight. The mice of transfection group were re-ceived an injection of SOCS3 plasmid or empty vector at every 7 days thereafter. Specimens were collected at 12 week after STZ injec-tion. The morphological changes of tubular epithelial cells were observed by transmission electron microscope. RT-PCR and immuno-histochemistry were used to determine the mRNA and protein expression of CK18 and α-SMA. Western blotting analysis was used to determine the protein expression of SOCS3, p-STAT3, CK18 and α-SMA. Results SOCS3 overexpression in kidney down-regulated the levels of p-STAT3 andα-SMA but up-regulated the expression of CK18. Conclusion Overexpression of SOCS3 can ameliorate the tubular epithelial-mesenchymal transdifferentiation of diabetic mice via inhibiting the phosphorylation of STAT3.
