摘要 目的研究α干扰素(IFNα-1b)对人肝癌细胞株HepG2细胞CD147、基质金属蛋白酶2(MMP-2)、金属蛋白酶组织抑制因子2(TIMP-2)表达的影响,探讨IFN-α抗肝细胞癌生长和转移复发的相关分子机制。方法培养HepG2细胞,在不同剂量的IFNα-1b干预下,于不同时间提取上清液,通过ELISA方法检测MMP-2、TIMP-2蛋白的表达,流式细胞仪检测CD147浓度变化。结果在HepG2细胞培养24及48h后,IFN-α剂量为3000IU/mL时的MMP-2蛋白浓度与空白对照组相比明显降低,分别为(1725.3±300.7)及(2899.8±343.2)pg/mL,差异均具有统计学意义(P<0.05);各时间段TIMP-2浓度与对照组比较差异均无统计学意义;MMP-2与TIMP-2浓度比值较对照组显著降低,差异具有统计学意义(P<0.05)。48hIFN-α干预组CD147平均荧光强度为54.6±23.3,与对照组相比差异具有统计学意义。结论大剂量的IFN-α可通过抑制HepG2细胞CD147表达水平降低MMP-2的分泌性表达,下调MMP-2与TIMP-2浓度比值,并呈剂量效应关系。IFN-α对HepG2细胞CD147、MMP-2表达的抑制作用在其抗肝细胞癌生长和转移复发中发挥一定作用。
