摘要
目的 构建乙型肝炎病毒 x基因真核表达载体并在肝癌细胞中表达 ,以研究其对肝癌细胞恶性表型的影响 .方法 应用 PCR、基因克隆等方法构建乙型肝炎病毒 x基因真核表达载体 pc DNA3.1 -HBX,用基因转染的方法将 pc D-NA3.1 -HBX转染入肝癌细胞 HCC-92 0 4,筛选稳定表达乙型肝炎病毒 X蛋白的肝癌细胞 .MTT比色实验、平板集落形成实验检测肝癌细胞恶性表型 .结果 成功构建了乙型肝炎病毒 x基因真核表达载体 pc DNA3.1 -HBX并获得了稳定表达乙型肝炎病毒 X蛋白的肝癌细胞系 HCC-92 0 4细胞克隆 ,且MTT比色实验、平板克隆形成实验显示稳定表达乙型肝炎病毒 X蛋白的肝癌细胞恶性度增高 .结论 乙型肝炎病毒 X蛋白具有生长因子样作用 ,可刺激肝癌细胞生长 ,在肝癌细胞中稳定表达乙型肝炎病毒 X蛋白可增加肝癌细胞恶性表型 .
