| 摘 要： | 目的研究水通道蛋白4(AQP4)在肺腺癌中的表达及其对肺腺癌细胞增殖与迁移的影响。方法收集20例经病理切片确诊的肺腺癌组织和4例癌周正常肺组织(距癌缘4～6cm,病理证实无肿瘤细胞),通过LSAB免疫组化法检测其中AQP4的表达。以APQ4-shRNA转染培养的肺腺癌细胞,通过Western blot法检测细胞中AQP4及E-cad-herin的表达;通过MTT法和Transwell小室法分别检测AQP4表达对肺腺癌细胞增殖与迁移的影响。结果 AQP4在肺腺癌组织中表达阳性率为55%(11/20),正常肺组织均为阴性。在肺腺癌细胞株中,AQP4均呈阳性表达且与E-cad-herin蛋白的表达呈负相关;AQP4的表达对肺腺癌细胞增殖无明显影响(P>0.05)。细胞迁移实验48h后,与对照组比较,AQP4-shRNA转染组细胞迁移显著减少(8.9%vs 14.8%,P<0.05)。结论 AQP4与肺腺癌的发生和迁移均相关;AQP4可能通过调节E-cadherin蛋白的表达而促进肺腺癌细胞的迁移。
