摘要 目的探讨miR-425对人胶质细胞瘤U87细胞迁移与侵袭能力的影响。方法利用Lipo2000转染试剂体外瞬时转染人胶质细胞瘤U87,将细胞分为实验组(转染miR-425 mimics)、抑制组(转染miR-425 inhibitors)、空白组(无转染)。Real-time PCR检测细胞中miR-425表达;划痕实验检测细胞的迁移距离,Transwell实验检测细胞的迁移以及侵袭能力,Western印迹检测基质金属蛋白(MMP)2、MMP9的表达水平。结果与空白组相比,miR-425 mimics组miR-425表达明显上调,约为空白组的8倍,细胞侵袭与迁移能力下降,MMP2、MMP9表达下降,miR-425 inhibitors组miR-425表达明显下调,约为空白组的0.14倍,细胞侵袭与迁移能力显著增强,MMP2、MMP9表达增强。结论 miR-425的表达水平与胶质瘤U87细胞的迁移与侵袭能力密切相关。
