Abstract： 目的:构建Cdh1小干扰RNA载体,并将其转染至Hela细胞进行鉴定.方法:根据pENTRTM/H1/TO中间载体要求,设计Cdh1小干扰RNA载体的干扰序列及无干扰作用的对照序列,合成相应的DNA单链,退火后连接到pENTRTM/H1/TO线性载体,形成完整载体,进行测序鉴定.分别将测序鉴定成功的Cdh1小干扰RNA载体及对照载体采用脂质体法转染Hela细胞,转染后48 h提取细胞总RNA及细胞总蛋白,采用实时定量PCR和Western Blot检测Cdh1的表达.结果:经测序鉴定成功构建Cdh1小干扰RNA载体和对照载体,分别命名为pENTR/shCdh1和pENTR/shcontrol.与未转染及转染pENTR/shcontrol的Hela细胞相比,转染pENTR/shCdh1的Hela细胞Cdh1表达降低(P《0.05).结论:成功构建Cdh1小干扰RNA载体,并能下调Hela细胞Cdh1的表达.
