摘    要:目的观察大豆甙元对子宫内膜癌细胞增殖及其雌激素受体(ER)表达的影响。方法体外培养子宫内膜癌HEC-1B细胞,采用MTT法检测不同浓度大豆甙元对子宫内膜癌细胞增殖的影响,同时检测大豆甙元对启动子(ERE)调控的ERα和ERβ的荧光素酶报告基因表达的影响。结果大豆甙元对HEC-1B细胞体外增殖有明显抑制作用,其抑制作用在一定范围内呈剂量及时间依赖性。大豆甙元在低浓度时已可显著诱导报告基因luc的表达,在80×10-6 mol/L时达到最高值;在高浓度时,其诱导作用逐渐下降;大豆甙元通过ERβ介导的报告基因表达水平的升高程度强于ERα。结论大豆甙元可抑制子宫内膜癌细胞的增殖,这种抑制作用可通过调节子宫内膜癌细胞ERα和ERβ的表达、调整ERα/ERβ比例而实现。

关 键 词:大豆甙元  子宫内膜癌  细胞增殖  雌激素受体  报告基因

Abstract:Objective To study the effect of daidzein on the proliferation of endometrial carcinoma and expression of estrogen receptor(ER).Methods Endometrial carcinoma cell HEC-1B were cultured in vitro.The influences of daidzein in different doses on the proliferation of HEC-1B cell were detected by using MTT method,and the estrogenic effects and the mechanism of daidzein were evaluated through the luciferase reportor gene assay.Results Daidzein inhibited significantly the proliferation of HEC-1B cells in vitro,and ...
Keywords:daidzein  endometrial caicinoma  proliferation  estrogen receptor  reportor gene
