摘要: 目的:克隆小鼠内皮抑素(mEndostatin)编码区cDNA序列并构建含Egr-1启动子的IFNγ和mEndostatin双基因表达载体。 方法:利用逆转录多聚酶链反应法(RT-PCR),以小鼠肝细胞mRNA为模板,扩增获得全长mEndostatin,与pMD18T载体连接作全自动测序,并利用基因重组技术构建含Egr-1启动子的IFNγ和mEndostatin双基因表达质粒。 结果:经测序证实获得的mEndostatin序列与文献报道完全一致,并构建了含Egr-1启动子的IFNγ和mEndostatin双基因表达质粒pEgr-IFNγ-mEndostatin。 结论:利用RT-PCR法成功克隆了mEndostatin的cDNA序列,构建了pEgr-IFNγ-mEndostatin重组双基因表达质粒。

Abstract: Objective To clone the sequence of the cDNA of mouse endostatin (mEndostatin) coding area and construct an expression vector containing Egr-1 promoter, IFNγ and endostatin genes. Methods Full length mEndostatin was obtained with the technique of RT-PCR and using mouse hepatocyte mRNA as template, pMD18T- mEndostatin was sequenced automatically and an expression vector containing Egr-1 promoter, IFNγ, and endostatin genes was constructed with gene recombinant technique. Results It was proved that the cloned mEndostatin cDNA to be completely identical with that reported in the literature and the recombinant plasmid containing Egr-1 promoter, IFNγ, and endostatin genes was constructed successfully. Conclusion mEndostatin cDNA was cloned and the expression vector pEgr-IFNγ-mEndostatin was constructed successfully.
