摘要
目的 探讨人类增殖性肾炎(PGN) 肾小球中胰岛素样生长因子1(IGF1) 的表达及其意义。方法 采用原位杂交、免疫组织化学方法检测肾活检组织中IGF1 mRNA及其蛋白质表达,并分析其与患者肾小球内细胞外基质(ECM) 增生的关系。结果 增殖性肾炎组中IGF1 的表达水平显著高于非增殖性肾炎组和正常组( P<0-01),IGF1 表达水平与ECM 增生程度呈正相关。结论 肾小球局部IGF1 基因异常表达参与了PGN的发病机制。
Objective To investigate the expression of insulin like growth factor 1(IGF 1)in glomerulus of patients with proliferative glomerulonephritis(PGN).Methods Expressions of IGF 1 mRNA and protein were examined by in situ hybridization and immunohistochemical staining.Results Glomerular IGF 1 expression of PGN increased significantly compared with other two groups.Conclusion The abnormal expression of IGF 1 is involved in pathogenesis of PGN.
