摘要 目的研究RNA干扰抑制整合素连接激酶(ILK)对人视网膜色素上皮(hRPE)细胞迁移的影响。方法体外培养hRPE细胞,设计并合成特异性人ILK的RNA干扰片段,脂质体转染入hRPE细胞,RT-PCR半定量检测siRNA对ILK基因表达的抑制,损伤愈合实验和Transwell实验观察hRPE细胞的迁移能力的变化。结果培养的hRPE细胞存在ILK的基因表达,siRNA显著抑制hRPE细胞ILK的表达,Transwell实验和损伤愈合实验提示转染ILK-siRNA后hRPE细胞的迁移能力较正常对照组下降(P<0.01)。结论特异性ILK-siRNA干扰片段能有效抑制ILK在hRPE细胞中的表达并显著降低其细胞的迁移能力。
