摘要:

采用分子克隆方法获得5拷贝口服长效促胰岛素多肽(rolGLP-1)和水蛭素(rHV)融合基因促胰岛素水蛭素(5rolGLP-HV), 并将该基因克隆至pET22b(+)表达载体上, 转化大肠杆菌BL21(DE3), 实现了高效表达. 表达产物经SDS-PAGE电泳及Western blot鉴定后用Ni-NTA]亲和层析柱纯化, 得到高纯度的5rolGLP-HV. 用STZ诱导Ⅱ型糖尿病小鼠和血栓模型鼠进行药物功能分析, 结果表明, 5rolGLP-HV有较好的降糖和抗血栓效果.

Abstract:

We constructed a fusion gene consisted of five copies longacting Glucagonlike peptide1 (rolGLP-1) and Hirudin (rHV) called 5rolGLP-HV by molecular cloning. 5rolGLP=HV gene was cloned into the expression vector pET22b (+) and translated into BL21 (DE3), and a highly expression bacterial strain was obtained. The expression product 5rolGLPHV was analyzed by SDS-PAGE electrophoresis and Western bolt, and was purified with NiNTA. Function analysis was performed via STZinduced type Ⅱ diabetic mice and thrombosis mice. The results show 5rolGLPHV has reducing blood glucose and antithrombotic effects.

Key words: diabetes mellitus, thrombosis, 5rolGLPHV; expression, purification, function analysis
