摘要:

目的: 探讨大豆黄素对有机氯农药诱导乳腺癌 MCF-7细胞增殖效应的抑制作用。方法:取对数生长期的MCF-7细胞,分别设含不同浓度的大豆黄素、氯丹、β-六六六 (β-HCH)、邻,对’ -滴滴涕 (o,p'-DDT)单独染毒组以及100 μmol/L大豆黄素与上述各农药联合作用组,并设溶剂对照 (0.1% 二甲基亚砜)组。培养48 h后,采用噻唑蓝 (MTT)实验检测MCF-7细胞的增殖情况。结果:与溶剂对照组相比,100 μmol/L的大豆黄素单独染毒组使MCF-7细胞的增殖率下降,不同浓度的有机氯农药单独染毒使MCF-7细胞的增殖率升高,差异均有统计学意义 (P<0.05)。与相应不同浓度的有机氯农药单独组相比,联合染毒组MCF-7细胞的增殖率明显下降,差异均有统计学意义 (P<0.05)。结论:大豆黄素能够抑制不同浓度有机氯农药诱导的MCF-7细胞的增殖效应。

Abstract:

 OBJECTIVE: To investigate the combined action of inhibitory daidzein and organochlorine pesticides on MCF-7 cell multiplication. METHODSMCF-7 human breast carcinoma cells in logarithmic growth phase were exposed to each of daidzein,chlordane,β-HCH,o,p'-DDT in different concentration alone and another group with 100 μmol/L daidzein combined with each pesticide. A solvent control group (0.1% DMSO) was set up. After 48 h of incubation,the cell multiplication was assessed by MTT. RESULTS:Compared with solvent group,the 100 μmol/L daidzein only group reduced cell multiplication. All different concentrations of each organochlorine pesticide could increase cell multiplication (P<0.05). Compared with the single agent treatment group,the rate of cell multiplication in combined treatment group was significantly reduced (P<0.05). CONCLUSION:Daidzein could inhibit cell multiplication induced by different concentrations of organochlorine pesticides.
