摘 要:目的观察微小RNA(mi R)-383对骨肉瘤细胞生物学特性的影响。方法脂质体转染骨肉瘤细胞(U-2OS),检测对细胞凋亡、增殖的影响,并检测细胞迁移侵袭能力、克隆形成能力的改变。结果细胞凋亡情况:空白对照组、无义序列组和实验组细胞的凋亡率分别为(8.56±1.45)%、(12.6l±1.37)%、(33.20±2.59)%,差异有统计学意义(P<0.05);细胞迁移实验:空白对照组、无义序列组和实验组分别为(82±5)个、(68±3)个和(45±7)个,差异有统计学意义(P<0.05);细胞迁移与侵袭实验:空白对照组、无义序列组和实验组细胞穿膜数分别为(82±5)个、(68±3)个和(45±7)个,以及(35±9)个、(32±4)个和(13±5)个,差异有统计学意义(P<0.05);克隆形成实验:空白对照组、无义序列组和实验组克隆数分别为(12.7±4.1)个、(12.3±3.6)个和(6.4±2.7)个。结论抑制mi R-383使骨肉瘤细胞凋亡增加,使细胞增殖、侵袭与迁移及克隆形成受到抑制。Objective To investigate effects of miRNA-383 on biological behaviors of osteosarcoma. Methods MiR-383 plasmid vectors were constructed and transfected into osteosarcoma cells. Flow cytometer was used to calculate the apoptotic rate. MTT Cell Proliferation Assay measured the cell proliferation rate. An analysis of cell migration and invasion was performed by Transwell Cell Migration / Invasion Matrigel Assay. Analysis of cell clonogenic ability was performed by Colony formation Assay.Results Apoptotic rate of control group, non-sense group and anti-miR-383 group: ( 8.56±1.45 ) %, ( 12.6l±1.37 ) %, ( 33.20±2.59 ) % with statistical signiifcance (P〈0.05 ). Migration test of control group, non-sense group and anti-miR-383 group: ( 82±5 ), ( 68±3 ) and ( 45±7 ) with statistical signiifcance (P〈0.05 ). Migration and invasion test of control group, non-sense group and anti-miR-383 group: ( 82±5 ), ( 68±3 ) and ( 45±7 ) compared with ( 35±9 ), ( 32±4 ) and ( 13±5 ) respectively, with statistical significance (P〈0.05 ). The clonogenic units of 3 groups: ( 12.7±4.1 ), ( 12.3±3.6 ) and ( 6.4±2.7 ).Conclusions MiR-383 can promote osteosarcoma cells’ apoptosis, and restrain proliferation, migration and invasion, and the colony formation.
