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.
