环磷酰胺在体外对大鼠肾小球系膜细胞增殖及凋亡的影响

目的:研究环磷酰胺(CTX)在体外对大鼠肾小球系膜细胞(GMC)增殖及细胞凋亡的影响。方法: 采用MTT法检测CTX、甲基强的松龙(MP)、低分子肝素(LMWH)对GMC细胞增殖的影响;采用光镜、荧光镜、流式细胞仪检测GMC细胞凋亡;GMC的Fas、Bcl-2蛋白质水平采用免疫组化法检测。结果:CTX、MP、LMWH均对GMC生长有抑制作用;CTX诱导GMC细胞凋亡, 使GMC的Fas蛋白水平增加。结论:CTX在体外可以抑制GMC细胞增殖, 可能通过Fas蛋白调节途径诱导GMC细胞凋亡。

Effect of cyclophosphamide on proliferation and apoptosis of rat mesangial cells in vitro

AIM: To investigate the effect of cyclophosphamide(CTX) on proliferation and apoptosis of mesangial cells(GMC) of rat in vitro. METHODS: GMC proliferation was detected by MTT method, GMC apoptosis was examined by inverted microscopy for phase-contract and fluoroscopy and flow cytometry analysis. The levels of Fas and Bcl-2 were also detected by immunohistology. RESULTS: The proliferation of GMC were inhibited by CTX, methylprednisolone(MP), low molecular weight heparin(LMWH). Apoptosis of GMC was induced by CTX, the apoptosis rate of GMC was 8.2%, and the Fas level was increased. CONCLUSION: CTX could inhibit proliferation and induce apoptosis of GMC possibly by enhancing the Fas level.
