摘要 目的:探讨miR-124对人成骨肉瘤MG-63细胞增殖的影响。方法:运用miR-124的模拟物或抑制剂分别转染人成骨肉瘤MG-63细胞,分别为实验组和对照组(脂质体2000),采用甲基噻唑基四唑(MTT)法检测细胞增殖情况。结果:对照组吸光度值(A值)在24h、48h和72h分别为(0.261±0.017)、(0.379±0.021)、(0.414±0.031);miR-124模拟物可抑制MG-63细胞增殖,其A值分别降至(0.149±0.006)、(0.163±0.007)、(0.212±0.009),差异具有显著统计学意义(P<0.01);miR-124抑制剂可促进MG-63细胞增殖,其A值分别增至(0.313±0.016)、(0.542±0.033)、(0.713±0.041),差异具有统计学意义(P<0.01)。结论:miR-124可抑制人成骨肉瘤细胞生长增殖活性,可作为一个抑瘤基因参与成骨肉瘤的发生与发展。
