摘要: 旨在构建敖汉细毛羊BMP4基因的质粒及转染成纤维细胞后研究基因表达量的变化。以30日龄的敖汉细毛羊胚胎为研究对象。首先,通过RNA的提取反转录成cDNA参照GenBank中BMP4基因序列信息设计1对引物,通过PCR反应扩增获得BMP4基因片段、将得到的BMP4基因连接到pEASYTM-T1载体,构建pEASYTM-T1-BMP4重组质粒并转化大肠杆菌(E.coli)DH5α感受态细胞提取质粒进行酶切鉴定。鉴定正确后构建pcDNA3.1-BMP4重组质粒,转化大肠杆菌(E.coli)DH5α感受态细胞;其次对敖汉细毛羊的成纤维细胞进行分离培养,并将重组pcDNA3.1-BMP4表达载体转染成纤维细胞,后检测BMP4基因在mRNA和蛋白水平上表达量的变化。结果显示:pcDNA3.1-BMP4构建成功后转染成纤维细胞BMP4基因的mRNA和蛋白表达量均显著上升,且转染组的表达量极显著地高于对照组(P < 0.01)。成功构建了敖汉细毛羊BMP4基因的质粒,并且成功转染成纤维细胞,基因在细胞中过表达,结果可为进一步研究其功能奠定基础。

Abstract: This study aims to construct the expression plasmid of BMP4 gene in AoHan sheep and explore the change of gene expression after transfection of fibroblasts. 30-day old AoHan sheep embryos were selected as the research subject. Firstly, a pair of primers was designed by reverse transcribing RNA into cDNA based on the sequence of BMP4 in GenBank. The BMP4 gene fragment was amplified by PCR reaction, and was ligated into pEASYTM-T1 vector to construct pEASYTM-T1-BMP4 recombinant plasmid, which was transformed into E.coli DH5α competent cells to extract the plasmid for restriction enzyme digestion. Then the fibroblasts of AoHan sheep were isolated and cultured, and the constructed plasmid pcDNA3.1-BMP4 was transfected into fibroblasts. The expression of BMP4 gene in fibroblasts was detected by quantitative PCR and Western Blot. The results showed that plasmid pcDNA3.1-BMP4 was successfully constructed by restriction enzyme digestion and sequencing, and BMP4 gene expression was significantly increased after transfection of fibroblasts. The expression level of transfection group was significantly higher than that of the control group. The plasmid was constructed and transfected into fibroblasts successfully. The result can be a basis for further study of its function.
