摘要 目的观察miR-124对人结肠癌SW620细胞生物学功能的影响。方法采用MTT实验、细胞划痕实验、Transwell侵袭实验检测miR-124对人结肠癌SW620细胞的生长、侵袭转移能力的影响。结果 MTT检测发现,过表达miR-124可抑制人结肠癌SW620细胞的生长,且具有时间依赖性;细胞划痕实验显示,转染miR-124成熟体12、24 h后伤口愈合率分别为26.5%±0.7%、37.7%±1.5%,其阴性对照分别为40.6%±2.5%、78.2%±1.6%,P<0.05;Transwell侵袭实验显示,转染miR-124成熟体24 h后穿过基底膜的人结肠癌SW620细胞数为(37±2.6)个,其阴性对照为(80±3.6)个,P<0.05。结论 miR-124可抑制人结肠癌细胞生长与侵袭。
