YAP1小干扰RNA对舌鳞状细胞癌生物学特性的影响
|
Abstract:
摘要 目的: 探讨小分子RNA干扰(siRNA)YAP1基因对舌鳞状细胞癌生物学特性的影响。方法: 培养人舌癌SCC-4细胞,根据转染物不同,分为siRNA-YAP1组、siRNA-对照序列组和空白对照组,实时荧光定量PCR技术检测各组细胞中YAP1基因表达,Western blot法检测各组细胞中YAP1蛋白表达,MTT法检测各组细胞增殖能力,流式细胞技术检测各组细胞凋亡情况,划痕实验检测各组细胞迁移能力,Transwell法检测各组细胞侵袭能力。结果: 与siRNA-对照序列组和空白对照组比较,siRNA-YAP1组细胞中YAP1 mRNA和蛋白相对表达量均降低,差异均有统计学意义(P<0.05);与siRNA-对照序列组和空白对照组比较,siRNA-YAP1组细胞24 h、48 h、72 h、96 h时A值均降低,差异均有统计学意义(P<0.05);与siRNA-对照序列组和空白对照组比较,siRNA-YAP1组细胞凋亡率均升高,差异有统计学意义(P<0.05);与siRNA-对照序列组和空白对照组比较,siRNA-YAP1组细胞划痕愈合率降低,差异有统计学意义(P<0.05);与siRNA-对照序列组和空白对照组比较,siRNA-YAP1组侵袭细胞数减少,差异有统计学意义(P<0.05)。结论: 特异性沉默人舌癌SCC-4细胞中YAP1基因可抑制细胞增殖,加速细胞凋亡,减少细胞迁移和侵袭能力
