Dietary Modulation of Intestinal Fructose Transport and GLUT5 mRNA Expression in Hypothyroid Rat Pups

Abstract

During weaning, dietary fructose can precociously enhance intestinal fructose uptake and GLUT5 mRNA expression, independent of developmental increases in serum thyroxine levels. Modest changes in glucose transport rates indicate that nonspecific mechanisms may provide a minor contribution to diet-induced changes in nutrient absorption in hypothyroid pups.
