摘要: ffaR-1在胰腺组织和神经系统中均有着重要作用,但其作用机制,尤其是在神经系统中的机制仍不清楚。以牛ffaR-1基因为研究对象,通过生物信息学预测并分析该基因的核心启动子区域,利用5’RACR技术扩增牛ffaR-1基因mRNA 5’UTR区域,同时构建牛ffaR-1基因真核表达载体并在真核细胞中进行表达。生物信息学分析表明,牛ffaR-1基因核心启动子属于TATA-less,Int-DPE类型;5’RACE结果将牛ffaR-1基因mRNA序列向上游推进了726 bp;成功构建了牛ffaR-1真核表达载体pIRES-EGFP-bffaR-1,并在真核细胞中进行了表达。从启动子序列、mRNA 5’UTR及真核细胞表达3个方面对牛ffaR-1基因进行了初步研究,为该基因功能及调控的相关研究提供理论和试验依据。

关键词: 游离脂肪酸受体1, 启动子, 真核表达

Abstract: FRee fatty acid ReceptoR 1( GPR40) is a G-pRotein coupled ReceptoR. When bound by fRee fatty acid, it can activate the intRacellulaR signal pathway and RegulaR the cell function. Many ReseaRches showed that the ffaR-1 played an impoRtant Role in pancReatic tissue and neRvous system. But the mechanism how it woRks is not cleaR,especially in neRvous system. PRedicts and analysises the coRe pRomoteR using bioinfoRmatics methods. Takes the use of 5' RACE technology to amplify the 5'UTR of bovine ffaR-1 mRNA. And constRucts the eukaRyotic expRession vectoR. The coRe pRomoteR of bovine ffaR-1 gene is the type of TATA-less and Int-DPE pRomoteR. PRolongs the mRNA of bovine ffaR-1 gene foRwaRd by 726 bp. And the eukaRyotic expRession vectoR woRds well in bovine fibRoblast cells. Studies the bovine ffaR-1 gene in 3 aspects, the pRomoteR sequence,mRNA 5' UTR,and eukaRyotic expRession and pRovides the theoRetical and expeRimental basis foR the ReseaRch of the function and Regulation of bovine ffaR-1 gene.

Key words: FRee fatty acid ReceptoR 1, PRomoteR, EukaRyotic expRession
