Fructose-induced increases in expression of intestinal fructolytic and gluconeogenic genes are regulated by GLUT5 and KHK.
Marked increases in fructose consumption have been tightly linked to metabolic diseases. One-third of ingested fructose is metabolized in the small intestine, but the underlying mechanisms regulating expression of fructose-metabolizing enzymes are not known. We used genetic mouse models to test the hypothesis that fructose absorption via glucose transporter protein, member 5 (GLUT5), metabolism...
متن کاملEffect of dietary fructose on portal and systemic serum fructose levels in rats and in KHK-/- and GLUT5-/- mice.
Elevated blood fructose concentrations constitute the basis for organ dysfunction in fructose-induced metabolic syndrome. We hypothesized that diet-induced changes in blood fructose concentrations are regulated by ketohexokinase (KHK) and the fructose transporter GLUT5. Portal and systemic fructose concentrations determined by HPLC in wild-type mice fed for 7 days 0% free fructose were <0.07 mM...
متن کاملCharacterization of the rabbit intestinal fructose transporter (GLUT5).
Recent studies suggest that the jejunal/kidney-type facilitative glucose transporter (GLUT5) functions as a high-affinity D-fructose transporter. However, its precise role in the small intestine is not clear. In an attempt to identify the fructose transporter in the small intestine, we measured fructose uptake in Xenopus oocytes expressing jejunal mRNA from five species (rat, mouse, rabbit, ham...
متن کاملAre Heart Muscle Irisin Levels and FNDC5 Gene Expression Regulated by Endurance and Resistance Exercises?
Background. Irisin is the result of the proteolysis of fibronectin type III domain-containing protein 5, the levels of which are determined by physical activity. Objective(s). This study aims to identify changes in FNDC5 gene expression and the heart muscle irisin levels in male rats following 8 weeks resistance and endurance training. Methods. Fifteen male rats (10-12 weeks old and 331.8&plu...
متن کاملGlucose and thyroid hormone co-regulate the expression of the intestinal fructose transporter GLUT5.
Expression of the fructose transporter GLUT5 in Caco-2 cells is controlled by the carbohydrate content of the culture media [Mesonero, Matosin, Cambier, Rodriguez-Yoldi and Brot-Laroche (1995) Biochem. J. 312, 757-762] and by the metabolic status of the cells [Mahraoui, Takeda, Mesonero, Chantret, Dussaulx, Bell, and Brot-Laroche (1994) Biochem. J. 301, 169-175]. In this study we show that, in ...
