Appearance of phloridzin-sensitive glucose transport is not controlled at mRNA level in rabbit jejunal enterocytes.

چکیده
Glucose uptake by rabbit intestine has been shown to be confined to the upper two-thirds of jejunal villi. Inhibition by phloridzin shows most of this transport to take place through the Na(+)-glucose linked transporter (SGLT1). Parallel measurements on the other hand show SGLT1 mRNA expression to increase rapidly as enterocytes reach the crypt-villus junction. Levels of SGLT1 mRNA then remain elevated in all villus enterocytes. These results provide direct evidence that SGLT1-mediated glucose transport is subject to post-transcriptional control.

Rapid enhancement of brush border glucose uptake after exposure of rat jejunal mucosa to glucose.
BACKGROUND Increased jejunal glucose transport after ingestion of carbohydrate rich diets may reflect higher concentrations of lumenal glucose. Normal processing of carbohydrate causes wide fluctuations in glucose concentration in the jejunal lumen and this raises the question of whether the high lumenal concentrations seen at peak digestion affect glucose uptake. AIMS To study the effects of...
متن کاملDiabetes mellitus and expression of the enterocyte renin-angiotensin system: implications for control of glucose transport across the brush border membrane.
Streptozotocin-induced (Type 1) diabetes mellitus (T1DM) in rats promotes jejunal glucose transport, but the trigger for this response remains unclear. Our recent work using euglycemic rats has implicated the enterocyte renin-angiotensin system (RAS) in control of sodium-dependent glucose transporter (SGLT1)-mediated glucose uptake across the jejunal brush border membrane (BBM). The aim of the ...
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 کاملInvolvement of the Niacin Receptor GPR109a in the Local Control of Glucose Uptake in Small Intestine of Type 2 Diabetic Mice
Niacin is a popular nutritional supplement known to reduce the risk of cardiovascular diseases by enhancing high-density lipoprotein levels. Despite such health benefits, niacin impairs fasting blood glucose. In type 2 diabetes (T2DM), an increase in jejunal glucose transport has been well documented; however, this is intriguingly decreased during niacin deficient state. In this regard, the rol...
متن کاملGlucose transport by epithelia prepared from harvested enterocytes
Transformed and cultured cell lines have significant shortcomings for investigating the characteristics and responses of native villus enterocytes in situ. Interpretations of results from intact tissues are complicated by the presence of underlying tissues and the crypt compartment. We describe a simple, novel, and reproducible method for preparing functional epithelia using differentiated ente...
