摘要: 目的 探讨2型糖尿病肾病(DN)患者肾组织中STOML2的表达及作用。方法 免疫组化检测临床2型糖尿病肾病患者肾组织STOML2的表达及定位,采用慢病毒转染方法建立稳定过表达STOML2的HK-2细胞系,并应用Western blot检测肾小管上皮细胞钙粘蛋白(E-cadherin)、Fibronectin和STOML2的表达。结果 STOML2在DN患者肾组织的肾小管上皮细胞胞浆中表达明显升高。在高糖刺激HK-2细胞建立的EMT模型中,STOML2呈时间依赖表达上调。STOML2稳定高表达时,E-cadherin表达下调,而Fibronectin明显上调,即能促进肾小管上皮细胞发生EMT。结论 STOML2可能通过促进肾小管上皮细胞向间充质细胞分化,进而参与糖尿病肾病肾脏纤维化的发生发展。

Abstract: Objective To investigate the expression and role of STOML2 in renal tissue of patients with type 2 diabetic nephropathy. Methods To detect he expression and localization of STOML2 in clinical renal tissue in patients with type 2 diabetic nephropathy by immunohistochemistry, and use lentiviral transfection method to establish a stable cell line of over-expressing STOML2, lastly apply western blot to detect the expression of E-cadherin, Fibronectin and STOML2 in renal tubular epithelial cells. Results STOML2 was significantly increased in renal tubular epithelial cytoplasm of patients with DN. In the EMT model of HK-2 cells stimulated by high glucose, STOML2 was increased in a time dependent. Overexpression of STOML2 led to E-cadherin down-regulated, while Fibronectin up-regulated, which promoted the occurrence of EMT in renal tubular epithelial cells. Conclusion STOML2 may be involved in the development and progression of renal fibrosis in diabetic nephropathy by mediating epithelial- mesenchymal transition of renal tubular epithelial cells.
