中文摘要:
      目的:观察miR-194 模拟物对于成骨肉瘤细胞系SOSP_9607 细胞增殖、周期和凋亡的影响。方法:四甲基偶氮唑蓝(MTT) 法绘制细胞生长曲线, 流式细胞仪测定细胞凋亡和周期。将SOSP_9607细胞分为对照组和实验组,对照组分为阴性对照和正常细 胞对照组。实验组采用miR-194 模拟物(hsa-miR-194 mimics)转染成骨肉瘤细胞系SOSP_9607,增强SOSP_9607细胞内miR-194 的活性。结果:与对照组比较,实验组细胞的增殖能力明显下降。实验组凋亡率(10.1±0.22)%与阴性对照组凋亡率(3.3±0.19)%相 比明显增高(P<0.01)。与对照组比较,实验组细胞周期G0/G1细胞比例显著增加,G2/M期细胞比例显著减少,S期细胞比例显著减 少(P<0.01)。结论:通过转染miR-194 模拟物增强SOSP_9607细胞中miR-194 的活性对SOSP_9607 细胞的增殖和凋亡造成显著 影响。
英文摘要:
      Objective: To investigate the effect of microRNA-194 mimics on proliferation, cell cycle and apoptosis of human osteosarcoma cell line SOSP-9607. Methods: MTT assay was used to detect cell growth. FCM was employed to detect cell apoptosis rate and cell cycle analysis. Cultured SOSP-9607 cells were divided into three groups:negtive control group, blank group and experimental group. In experimental group, hsa-miR-194 mimics were used to increase the activity of miR -194. Results: Hsa-miR-194 mimics inhibited SOSP-9607 cell proliferation, while the control group had no obvious effect on cell proliferation. The apoptosis ratio of the experimental group[(10.1±0.22)%] was obviously higher than that of the control group[(3.3±0.19)%](P<0.01). Hsa-miR-194 mimics increased the cell ratio of G0/G1 phase, simultaneously decreased significantly the cell ratios of G2/M phase and S phase.( P<0.01). Conclusion:
