目的 研究反義硫代磷酸寡核苷酸(AS-ODN)抑制人肝癌細(xì)胞耐藥株(SMMC-7721/ADM)MRP基因表達(dá)的作用。
方法 用人工合成互補(bǔ)于MRP基因mRNA特定片斷的反義硫代磷酸寡核苷酸,以脂質(zhì)體Lipofectamine為載體轉(zhuǎn)染SMMC-7721/ADM細(xì)胞株,用RT-PCR測(cè)定mRNA表達(dá),流式細(xì)胞技術(shù)測(cè)定細(xì)胞膜MRP1蛋白P190表達(dá)及MTT法檢測(cè)細(xì)胞對(duì)柔紅霉素(DNR)和阿霉素(ADM)的敏感性。
結(jié)果 AS-ODN能抑制MRP mRNA和其蛋白P190表達(dá),提高細(xì)胞對(duì)DNR和ADM的敏感性。
結(jié)論 ①AS-ODN能降低MRP基因表達(dá); ②MRP介導(dǎo)的多藥耐藥(MDR)是SMMC-7721/ADM耐藥的重要機(jī)理之一。
