Intestinal fructose transport and malabsorption in humans.
Fructose is a hexose sugar that is being increasingly consumed in its monosaccharide form. Patients who exhibit fructose malabsorption can present with gastrointestinal symptoms that include chronic diarrhea and abdominal pain. However, with no clearly established gastrointestinal mechanism for fructose malabsorption, patient analysis by the proxy of a breath hydrogen test (BHT) is controversia...
متن کاملDexamethasone Promotes the Risk of Cardiovascular Disease in High Fructose-exposed Wistar Rats
Background: Dyslipidemia constitutes a serious public health concern globally. It has been established that excessive fructose intake results in dyslipidemia; however, whether dexamethasone aggravates or alleviates fructose-induced dyslipidemia is unknown. Thus, we examined the effects of dexamethasone on dyslipidemia and hyperuricemia in high fructose-taking Wister rats. Methods: Twenty male...
متن کاملFructose-induced increases in neonatal rat intestinal fructose transport involve the PI3-kinase/Akt signaling pathway.
Expression of rat glucose transporter-5 (GLUT5) is tightly regulated during development. Expression and activity are low throughout the suckling and weaning stages, but perfusion of the small intestinal lumen with fructose solutions during weaning precociously enhances GLUT5 activity and expression. Little is known, however, about the signal transduction pathways involved in the substrate-induc...
متن کاملLuminal fructose modulates fructose transport and GLUT-5 expression in small intestine of weaning rats.
In neonatal rats, precocious introduction of dietary fructose significantly enhances brush-border fructose transport rates and GLUT-5 mRNA levels during early weaning. In this study, these rates and levels were more than two times higher in the anastomosed intestine compared with those in the bypassed loop of weaning pups that underwent Thiry-Vella surgery and consumed high-fructose (HF) diets....
متن کاملExcessive fructose intake causes 1,25-(OH)(2)D(3)-dependent inhibition of intestinal and renal calcium transport in growing rats.
We recently discovered that chronic high fructose intake by lactating rats prevented adaptive increases in rates of active intestinal Ca(2+) transport and in levels of 1,25-(OH)2D3, the active form of vitamin D. Since sufficient Ca(2+) absorption is essential for skeletal growth, our discovery may explain findings that excessive consumption of sweeteners compromises bone integrity in children. ...
