【摘要】 目的 研究磷脂酰肌醇3激酶调节亚基1(PIK3R1)表达对肝细胞癌(HCC)进展的影响。 方法 免疫组化和逆转录- 定量聚合酶链反应(RT- qPCR)检测HCC组织中PIK3R1表达。RT- qPCR和免疫印迹检测不同HCC细胞系中PIK3R1 mRNA和蛋白表达,选择MHCC97H、HCCLM3细胞作为模型研究PIK3R1对HCC进展的影响。溴化噻唑蓝四氮唑(MTT)实验、克隆形成实验、划痕愈合实验和流式细胞术评价PIK3R1下调对HCC细胞增殖、迁移和凋亡的影响。蛋白印迹分析评估PI3K/蛋白激酶B(Akt)/mTOR信号传导通路的表达变化。 结果 HCC组织中PIK3R1表达与相邻正常组织相比,显著上调。下调PIK3R1表达抑制HCC细胞系增殖、迁移并促进其凋亡。PIK3R1下调还抑制MHCC97H、HCCLM3细胞中p- PI3K、p- Akt和p- mTOR表达。 结论 HCC中PIK3R1表达显著上调,沉默PIK3R1可抑制HCC细胞系增殖、迁移并加速凋亡,其可能是未来HCC治疗的潜在靶点。
