1、医学临床研究2013年11月第3o卷第11期JClinRes,Nov.2013,Vol30,No11·论著·姜黄素对人肝癌细胞株HepG2巨噬细胞迁移抑制因子表达的影响李勇肖雅玲陈朝晖黎明李青玲邹欣周海燕。(1.湖南省儿童医院普外二科,湖南长沙410007;2.中南大学基础医学院病理学系,湖南长沙410013)[摘要]【目的】检测人肝癌细胞株HepG2中巨噬细胞迁移抑制因子(MIF)的表达及释放,探讨姜黄素对HepG2中MIF表达的影响。【方法】反转录聚合酶链反应(RT_PCR)及免疫印迹法(WesternBlot)检测对照组及不同浓度姜黄素干预组
2、(1O,2O,3O,40,50fmol/L)HepG2中MIFmRNA及蛋白表达水平;ELlSA检测对照组及不同浓度姜黄素干预组(10,2O,30,40,50/2mol/I)培基中MIF蛋白水平。【结果】HepG2高表达MIFmRNA及MIF蛋白,各浓度姜黄素干预均可抑制HepG2中MIFmRNA及MIF蛋白的表达,且呈浓度依赖效应(Pd0.05);HeF,G2可自分泌MIF蛋白,各浓度姜黄素干预均可抑制HepG2中MIF蛋白的释放,且呈浓度依赖效应(Pd0.05)。【结论l-e肝癌细胞株HepG2可表达及释放MIF;姜黄素在转录和翻译水平能有效抑
