目的:探讨牛蒡子苷元(ARG)对子宫内膜癌HEC-1B细胞的增殖抑制作用及机制。方法:HEC-1B细胞分为观察组和对照组,观察组用终浓度为10、20、30、40、60、100 μmol/L的ARG干预,对照组用0.5%二甲基亚砜(DMSO)干预。48 h后,用四甲基偶氮唑盐微量酶反应比色法(MTT法)检测胞增殖情况;流式细胞仪检测细胞凋亡及细胞周期;蛋白免疫印迹法(WB)检测细胞NF-κB信号通路相关蛋白表达。结果:10、20、30、40、60、100 μmol/L ARG干预48 h,HEC-1B细胞的相对生存率分别为(92.36±0.52)%、(89.59±0.74)%、(78.49±0.68)%、(56.47±0.59)%、(40.12±0.69)%、(37.52±0.58)%,且随着ARG作用浓度的升高,HEC-1B细胞的相对生存率呈逐渐降低趋势,差异有统计学意义(P<0.05),干预48 h HEC-1B细胞50%抑制浓度(IC50)为50 μmol/L。对照组和观察组(50 μmol/L ARG)细胞凋亡率分别为(2.89±0.56)%、(26.58±3.26)%,观察组细胞凋亡率明显高于对照组,差异有统计学意义(P<0.05)。但观察组细胞周期分布与对照组比较,差异无统计学意义(P>0.05)。观察组(50 μmol/L ARG)细胞p65、p-IκB-α蛋白表达量明显低于对照组,差异有统计学意义(P<0.05),2组间IκB-α蛋白表达量差异无统计学意义(P>0.05)。结论:ARG可抑制HEC-1B细胞增殖,促进其凋亡,其作用机制与可能与降低NF-κB通路相关蛋白表达水平,抑制NF-κB通路活化有关。 |
English Summary: |
To investigate the proliferation inhibition effect of Arctigenin (ARG) on endometrial carcinoma HEC-1B cell and its mechanism.Methods:HEC-1B cells were divided into test group and control group.The test group was intervened with ARG at the final concentration of 10,20,30,40,60,100 μmol/L,and the control group was intervened with 0.5% dimethyl sulfoxide (DMSO).48 h after incubation,the proliferation was detected by MTT assay.The cell apoptosis and cell cycle were detected by flow cytometry.The expression of NF-κB signaling pathway related proteins were detected by western blotting (WB).Results:The relative survival rates of HEC-1B cell intervened with 10,20,30,40,60 and 100 mol/LARG after 48 h were (92.36±0.52)%,(89.59±0.74)%,(78.49±0.68)%,(56.47±0.59)%,(40.12±0.69)%,(37.52±0.58)% respectively,with the increase of ARG concentration.The relative survival rates of HEC-1B cells decreased gradually (P<0.05).50% inhibitory concentration (ID50) of HEC-1B cells intervened with ARG after 48 h was 50 μmol/L.The apoptosis rates of HEC-1B cells in the control group and the test group (50 μmol/L ARG) were (2.89±0.56)%,(26.58±3.26)% respectively.The apoptosis rate in the test group was significantly higher than that in the control group (P<0.05).However,there was no significant difference in cell cycle distribution between the test group and the control group (P>0.05).The expression levels of p65 and p-IκB-α in the test group (50 μmol/L ARG) were significantly lower than that in the control group (P<0.05).There was no significant difference in the expression levels of IκB-α between the test group and the control group (P>0.05).Conclusion:ARG can inhibit the proliferation and promote apoptosis of HEC-1B cells,and its mechanism may be related to decreasing the expression level of NF-κB related protein and inhibiting the activation of NF-κB pathway. |
