摘要 目的构建和鉴定人骨诱导因子基因(hOGN)和绿色荧光蛋白(GFP)共表达慢病毒载体,并检测其在人大肠癌细胞株HT-29中的表达水平。方法采用PCR方法克隆hOGN基因;将hOGN基因连接到带有GFP的慢病毒表达载体pEZ-Lv201中构建慢病毒载体;将构建的慢病毒载体质粒pEZ-hOGN-SV40-eGFP-IRES-Puro(pEZ-hOGN)与慢病毒包装质粒混合物Lenti-PacHIVmix共转染293T细胞,收集慢病毒悬液;重组病毒转染H1299细胞,定量PCR法检测重组病毒滴度;将构建的pEZ-hOGN感染HT-29细胞,荧光显微镜观察和Western印迹检测感染后HT-29细胞中GFP表达情况和目的基因hOGN的表达情况。结果基因测序分析证实克隆的hOGN基因与GenBank提供的序列完全一致;构建的重组慢病毒载体经双酶切、琼脂糖凝胶电泳鉴定证实OGN正确插入pEZ-Lv201;定量PCR测定慢病毒滴度为0.1×10~9~1×10~9TU/ml。在HT-29细胞中重组病毒感染96h后在荧光显微镜下可检测到较强的绿色荧光蛋白表达,Western印迹检测到在HT-29细胞中hOGN蛋白过表达。结论成功构建携带hOGN基因的重组慢病毒载体,在HT-29细胞中有效表达。
