杜仲雌激素样作用实验研究

目的用体外实验检测杜仲的雌激素样作用,并对其可能的作用机制进行探讨。方法采用MCF-7细胞增殖实验对杜仲进行雌激素样活性筛选,稳定转染ERα-ERE、ERβ-ERE荧光素酶报告基因的HEK293细胞荧光表达实验、蛋白质免疫印迹法探讨其作用机制。结果杜仲在0.5~1 mg/ml时可诱导MCF-7细胞增殖,1 mg/ml杜仲能显著促进ERE报告基因荧光素酶表达,差异有统计学意义(P<0.05、P<0.01或P<0.001),1 mg/ml可上调雌激素受体ERα、ERβ的蛋白表达,0.5~1 mg/ml可上调雌激素膜受体GPR30的表达。结论杜仲具有雌激素样作用,其作用机制在于能与雌激素受体结合发挥作用。
