摘要: 目的:初步探讨mTOR抑制剂AZD2014对肝癌细胞的增殖抑制作用及其机制。方法:先采用CCK-8法检测不同浓度的AZD2014(10、100、500、1 000 nmol/L)对肝癌细胞增殖的作用,再分别采用荧光定量PCR和Western blot法检测肝癌细胞中含植物同源结构和环指域泛素样蛋白1(UHRF1)mRNA和蛋白的表达水平。结果:细胞增殖实验结果显示,10、100、500、1 000 nmol/L的AZD2014均可显著抑制肝癌细胞的增殖能力,抑制程度与其浓度呈正相关(P < 0.05);荧光定量PCR和Western blot检测结果显示,500和1 000 nmol/L的AZD2014可显著降低肝癌细胞内UHRF1 mRNA及蛋白的表达水平。结论:AZD2014可能通过抑制肝癌细胞内UHRF1的表达水平来抑制肝癌细胞的增殖能力。

Abstract: OBJECTIVE: To investigate the effect of mTOR inhibitor,AZD2014,on proliferation of HCC cells. METHODS: The CCK-8 method was used to detect proliferation of HCC cells after their treatment with different concentrations of AZD2014 (10,100,500,1 000 nmol/L). Expression levels of UHRF1 mRNA and protein were detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western Blot,respectively. RESULTS: The CCK-8 results show that different concentrations of AZD2014 (10,100,500,1 000 nmol/L) significantly inhibited proliferation of hepatoma cells,and the degree of inhibition was positively dose-dependent. In addition,the RT-PCR and Western Blot data show that AZD2014 at concentrations of 500 nmol/L and 1 000 nmol/L reduced the expression of UHRF1 mRNA and protein in HCC cells. CONCLUSION: AZD2014 inhibited proliferation of HCC cells by repressing expression of UHRF1.
