摘要 目的:研究雷帕霉素对人胰腺癌细胞SW1990的mTOR信号通路的影响。方法:采用免疫细胞化学证实mTOR信号通路的存在,通过CCK-8法研究雷帕霉素对胰腺癌细胞增殖的影响,通过Western blot和real time PCR分别从蛋白水平和基因水平研究雷帕霉素对mTOR及其下游分子的表达。结果:免疫细胞化学结果显示p-mTOR、p-p70S6K、p-4E-BP1在细胞质中均呈阳性;CCK-8法显示雷帕霉素能明显抑制细胞增殖(P<0.05);Western blot结果显示随着雷帕霉素浓度的增加,p-mTOR、p-p70S6K表达明显减少,而p-4E-BP1蛋白表达明显增加(P<0.05);Real-time PCR结果显示随雷帕霉素浓度的增加,CyclinD1、VEGF、c-myc基因表达明显减少(P<0.05)。结论:人胰腺癌细胞系SW1990中存在mTOR信号通路并处于激活状态;雷帕霉素抑制胰腺癌细胞增殖与雷帕霉素抑制mTOR信号通路活化有关。 目的:研究雷帕霉素对人胰腺癌细胞SW1990的mTOR信号通路的影响。方法:采用免疫细胞化学证实mTOR信号通路的存在,通过CCK-8法研究雷帕霉素对胰腺癌细胞增殖的影响,通过Western blot和real time PCR分别从蛋白水平和基因水平研究雷帕霉素对mTOR及其下游分子的表达。结果:免疫细胞化学结果显示p-mTOR、p-p70S6K、p-4E-BP1在细胞质中均呈阳性;CCK-8法显示雷帕霉素能明显抑制细胞增殖(P&lt;0.05);Western blot结果显示随着雷帕霉素浓度的增加,p-mTOR、p-p70S6K表达明显减少,而p-4E-BP1蛋白表达明显增加(P&lt;0.05);Real-time PCR结果显示随雷帕霉素浓度的增加,CyclinD1、VEGF、c-myc基因表达明显减少(P&lt;0.05)。结论:人胰腺癌细胞系SW1990中存在mTOR信号通路并处于激活状态;雷帕霉素抑制胰腺癌细胞增殖与雷帕霉素抑制mTOR信号通路活化有关。
