摘  要:
利用PCR方法从猪基因组DNA中扩增了1.2 kb的肌肉生长抑制素(myostatin)基因启动子序列。并进一步以绿色荧光蛋白(GFP)为报告基因,构建了真核表达载体MSTNPro-EGFP;通过转染C2C12小鼠骨骼肌成肌细胞和猪成纤维细胞,对猪myostatin基因启动子的转录调控活性进行鉴定。结果表明:猪myostatin基因启动子可以启动GFP在C2C12细胞中的转录和表达,而将猪MSTNPro-EGFP载体转染猪胎儿成纤维细胞后并未观察到GFP的表达,说明myostatin基因表达的肌肉特异性源于启动子的转录特异性。

摘  要:
In this study myostatin gene promoter was obtained from porcine genomic DNA by PCR method.Then the eukaryotic expression vector MSTNPro-EGFP was constructed with green fluorescent protein(GFP) as a reporter gene.The transcriptional regulation activity of porcine myostatin promoter was identified by transfecting the vector into C2C12 mouse skeletal muscle myoblast cell line and porcine fibroblasts.The results showed that porcine myostatin promoter could start transcription and expression of GFP in C2C12,but not in porcine fetal fibroblast.It suggested that the specificity of myostatin gene expression comes from transcription of the promoter.
