CUEDC2通过上皮-间质转化促进人乳腺癌MCF-7细胞侵袭转移
Journal of Modern Oncology（2016）
Abstract
目的:探讨CUE结构域2(CUE domain-containing 2,CUEDC2)蛋白对人乳腺肿瘤细胞侵袭转移的作用机制.方法:人乳腺肿瘤细胞MCF-7转染的Myc-CUEDC2真核表达载体,提取转染细胞的总蛋白和总RNA进行蛋白免疫印迹和实时定量PCR检测上皮-间质转化(EMT)标志物上皮-钙黏蛋白(E-cadherin)和转录因子SLUG的表达.结果:过表达CUEDC2蛋白能够下调E-cadherin蛋白和基因的表达,而上调转录因子SLUG基因和蛋白的表达.结论:CUEDC2可能参与调节乳腺肿瘤细胞发生上皮-间质转化,促进乳腺肿瘤侵袭转移的发生,CUEDC2可能是人乳腺肿瘤侵袭转移的治疗靶点.
