摘要:

为了研究转录因子USF1在鸡小肠上皮细胞中调控糖转运蛋白基因表达的机制,本试验在生物信息学分析的基础上通过构建真核表达载体pcDNA3.1-USF1,在鸡小肠上皮细胞中过表达转录因子USF1,用绝对荧光定量PCR的方法检测分析了USF1对SGLT1、GLUT2和GLUT5基因表达的影响。结果表明,受到USF1基因过表达的影响,糖类转运蛋白GLUT2和SGLT1 mRNA在鸡小肠上皮细胞中的表达量极显著增高(P<0.01);而GLUT5 mRNA表达量没有显著变化(P>0.05)。结合本研究结果,经过对这3个糖类转运蛋白基因5′上游调控区USF1结合位点的深入分析,认为在鸡小肠上皮细胞中转录因子USF1对糖转运蛋白基因GLUT2和SGLT1的表达具有正向调控的作用。

Abstract:

In order to study the potential regulation mechanism of the USF1 on monosaccharide transporters in chicken intestinal epithelial cells,we built the eukaryote expression vector pcDNA3.1-USF1 on the basis of bioinformatics analysis and made the transcription factor USF1 over-expressed in chicken intestinal epithelial cells.Besides,we detected and analyzed the influence of USF1 on the mRNA expressions of SGLT1,GLUT2 and GLUT5 by Real-time PCR.The results indicated that the over-expression of USF1 gene significantly up-regulated the mRNA expressions of GLUT2 and SGLT1 in chicken intestinal epithelial cells(P<0.01),while the expression of GLUT5 were not changed significantly(P>0.05).Combining the results with the bioinformatics analysis of the USF1 binding sites on the 5′up-stream regulation area of the 3 monosaccharide transporters,our results indicated that the transcription factor USF1 positively regulated the expression of SGLT1 and GLUT2 in chicken intestinal epithelial cells.
