The regulation of glucose and sodium butyrate transporters(glucose transporter1-5 and Monocarboxylate transporter 1) and their relationship with cell apoptosis induced bysodium butyrate in colonic caner cell line HT-29 were studied. Cell apoptosis was detectedby flow cytometric assay. The expression of MCT1 and GLUT1-5 mRNA were detected byRT-PCR and the uptake of glucose was detected using 2-deoxy-[3H]glucose. The expressionof bax and bcl-x/l were detected by westernblot assay. We found that sodium butyrateinduced apoptosis in HT-29 cell line. The expression of GLUT1 mRNA, bcl-x/l, as well theuptake of glucose was inhibited by sodium butyrate. The expression of MCT1 and GLUT2,GLUT3, GLUT5 was not regulated by sodium butyrate. However, the concentration ofglucose had positive correlation with the expression of bcl-x/l protein and negativecorrelation with the apoptosis induced by sodium butyrate. All the results suggested thatdownregulation of the expression of GLUT1 was associated with the apoptosis induced bysodium butyrate in HT-29 cell line. View Full-Text
