摘要
目的研究环境雌激素双酚A(bisphenol A,BPA)对离体人子宫肌瘤细胞增殖的影响。方法进行人子宫肌瘤细胞原代、传代培养及鉴定。取用第3～5代子宫肌瘤细胞,用3种剂量的BPA(1×10-7、50×10-7、100×10-7mol/L)干预24、48、72h,并设溶剂对照组(无水乙醇,体积比为0.1%);采用噻唑蓝(MTT)法及流式细胞术对子宫肌瘤细胞的增殖情况进行分析。结果成功建立了人子宫肌瘤细胞有限细胞系。100×10-7mol/LBPA作用于子宫肌瘤细胞24、48、72h,及50×10-7mol/LBPA作用48、72h可促进子宫肌瘤细胞增殖,与溶剂对照组比较,差异均有统计学意义(P<0.05,P<0.01);50×10-7和100×10-7mol/LBPA作用72h时可促进G0-G1期细胞进入S期,提高细胞分裂增殖指数(PI),与溶剂对照组比较,差异有统计学意义(P<0.05,P<0.01)。结论BPA能促进离体人子宫肌瘤细胞增殖,而且其促增殖作用存在时间依赖和剂量依赖关系,提示环境雌激素BPA对子宫肌瘤的发生、发展有促进作用。
Objective To study the effect of environmental estrogen, bisphenol A (BPA), on proliferation of human uterine leiomyoma cells in culture. Methods The primary culture and subculture of the human uterine leiomyoma cells which were identified at each passage by means immunocytochemical staining with a monoclonal anti-α-smooth muscle actin antibody, were performed. The cells (passage 3-5) were incubated with BPA (including three dosimetric systems, 1×10-7 mol/L, 50 ×10-7 mol/L and 100×10-7 mol/L) for 24, 48 and...
