摘要(Abstract)：
目的构建反义基本转录元件结合蛋白2(BTEB2)重组腺病毒载体,并研究BTEB2反义RNA对动脉损伤后内皮修复的影响。方法通过RTPCR从培养的大鼠血管平滑肌细胞(VSMC)中制备BTEB2cDNA,将其反向克隆至腺病毒载体,构建反义BTEB2重组腺病毒;用重组腺病毒局部转染球囊损伤的大鼠颈动脉,观察反义BTEB2基因转染对BTEB2蛋白表达及损伤内皮修复的影响。结果构建的BTEB2反义重组腺病毒经鉴定正确,其滴度为5×1010pfumL;反义BTEB2重组腺病毒转染可显著抑制BTEB2蛋白表达,明显促进内皮的修复,改善损伤动脉的内皮依赖性舒张功能。结论成功构建了反义BTEB2重组腺病毒载体。BTEB2反义基因转染可显著促进大鼠颈动脉球囊损伤后的内皮修复。
