摘要 目的探讨不同浓度17-β雌激素(E2)对雌激素受体(ER)阴性的子宫内膜腺癌细胞系JEC的作用。方法采用四甲基偶氮唑蓝(MTT)比色法观察不同浓度(10-4、10-5、10-6、10-7、10-8、10-9、10-10、10-11和10-12 mol/L)E2作用JEC1d、2d、3d、4d、5d后细胞的增殖活性。结果不同浓度的E2作用JEC细胞1d、2d、3d后,其OD值和对照组相比无明显差异;作用4d、5d后10-7、10-8和10-9 mol/L组OD值和对照组比较有差异,其中10-7mol/L组在第5天OD值与对照组比较有显著差异。结论一定浓度的雌激素能促进JEC细胞的增殖。 Objective To observe the effects of different concentration of 17-β estrogen(E2) on endometrial adenocareinoma cell line JEC of estrogen receptor negative . Metheds To test the effects of different concentration of estrogen (10^-4、10^-5、10^6、10^-7、10^-8、10^-9、10^-10、10^-11 and 10^-12 mol/L On endometrial adenoearcinoma cell line JEC at 1、2、3、4,Sday by MTT assay. Results The optical density of JEC in 10^-7、10^-8 and 10^-9 mol/L concentration of E2 on endometrial adenocarcinoma cell line JEC at 4,Sday was higher than that in control group (P〈0.05). Likewise,this in 10^-7 mol/L concentration of E2 at 5day was more high than that in control group (P〈0.01). Conelusion It is suggested in the present study that estrogen can stimulate the proliferation of endometrial adenoearcinoma cell line JEC.
