摘要 目的探讨沉默雷帕霉素靶蛋白(m TOR)雷帕霉素不敏感组分(RICTOR)表达对血管瘤细胞侵袭、迁移能力的影响及作用机制。方法采用RNA干扰技术降低血管内皮瘤细胞EOMA中RICTOR的表达量,实验分为对照组、阴性组、转染组,Transwell法检测降低RICTOR表达对细胞侵袭、迁移能力的影响,Western印迹检测细胞中RICTOR、丝苏氨酸蛋白激酶(AKT)、磷酸化AKT(p-AKT)、基质金属蛋白酶(MMP)-9蛋白的表达量。结果转染后细胞中RICTOR蛋白的表达量显著降低(P<0.05);沉默RICTOR表达可显著降低细胞的侵袭、迁移能力(P<0.05);转染组细胞中AKT蛋白的表达量没有明显变化,p-AKT、MMP-9蛋白的表达量显著低于对照组(P<0.05)。结论沉默RICTOR表达可通过降低磷脂酰肌醇-3激酶(PI3K)/AKT信号通路和MMP-9的表达抑制血管内皮瘤细胞EOMA的侵袭、迁移能力。
