果糖转运蛋白(GLUT-5)的表达在断奶中期大鼠小肠中较低,在断奶完成后正常增加,并且可以通过过早食用高果糖(HF)饮食而过早诱导。在这项研究中,体内灌注模型被用来确定调节这种底物诱导的GLUT-5发育重编程的机制。HF(100 mM)而不是高葡萄糖(HG)灌注增加GLUT-5活性和mRNA丰度。相反,HF和HG灌注对Na+依赖性葡萄糖转运蛋白(SGLT-1)表达没有影响,但增加了c-fos和c-jun表达。肠灌注前腹腔注射放线菌素D可阻断HF诱导的果糖摄取率和GLUT-5 mRNA丰度的增加。放线菌素D还阻止了灌注诱导的c-fos和c-junmRNA丰度的增加,但不影响葡萄糖摄取率和SGLT-1 mRNA丰度。放线菌酮阻断HF诱导的果糖摄取率增加,但不阻断GLUT-5 mRNA丰度增加,对葡萄糖摄取率和SGLT-1 mRNA丰度无影响。在新生大鼠中,底物诱导的肠道果糖转运重编程可能涉及GLUT-5基因的转录和翻译。
Fructose transporter (GLUT-5) expression is low in mid-weaning rat small intestine, increases normally after weaning is completed, and can be precociously induced by premature consumption of a high-fructose (HF) diet. In this study, an in vivo perfusion model was used to determine the mechanisms regulating this substrate-induced reprogramming of GLUT-5 development. HF (100 mM) but not high-glucose (HG) perfusion increased GLUT-5 activity and mRNA abundance. In contrast, HF and HG perfusion had no effect on Na+-dependent glucose transporter (SGLT-1) expression but increased c-fosand c-junexpression. Intraperitoneal injection of actinomycin D before intestinal perfusion blocked the HF-induced increase in fructose uptake rate and GLUT-5 mRNA abundance. Actinomycin D also prevented the perfusion-induced increase in c-fosand c-junmRNA abundance but did not affect glucose uptake rate and SGLT-1 mRNA abundance. Cycloheximide blocked the HF-induced increase in fructose uptake rate but not the increase in GLUT-5 mRNA abundance and had no effect on glucose uptake rate and SGLT-1 mRNA abundance. In neonatal rats, the substrate-induced reprogramming of intestinal fructose transport is likely to involve transcription and translation of the GLUT-5 gene.
