D‐[3H]mannoheptulose was recently reported to be poorly taken up by tumoral pancreatic islet cells of the RINm5F and INS‐1 lines. We have now investigated the effects of D‐mannoheptulose upon D‐glucose metabolism in these two cell lines. D‐

D-Mannoheptulose was recently postulated to be transported into cells by GLUT2. The validity of such an hypothesis was assessed by comparing the uptake of tritiated D-mannoheptulose by pancreatic islets versus pieces of pancreas and, in the latter ca

In order to assess the respective contribution of the exocrine and endocrine moieties of the pancreas to the overall net uptake of selected monosaccharides by the pancreatic gland, the apparent distribution space of L-[1-14C]glucose, 3-O-[14C-methyl]

Hepatocytes from fed rats were incubated for 120 min in the presence of alpha-D-[1,2-13C]glucose pentaacetate (1.7 mM), both D-[1,2-13C]glucose (1.7 mM) and acetate (8.5 mM), alpha-D-glucose penta[2-13C]acetate (1.7 mM), or D-[1,2-13C]glucose (8.3 mM

The tetra-acetate ester of 2-deoxy-D-glucose was recently found to either inhibit or augment insulin secretion, depending on the concentration of the ester. Both the positive and negative insulinotropic actions of the ester display anomeric specifici

The early (min/= 1) and late (min 45) changes in NAD(P)H fluorescence caused by alpha-D-glucose pentaacetate, beta-L-glucose pentaacetate, and beta-D-galactose pentaacetate (1.7 mM each), alone or together with either L-leucine (10.0 mM) or D-glucose

The effects of α- and β-2-deoxy-d-glucose tetraacetate (1.7 and 8.5 mM) on insulin, somatostatin, and glucagon secretion from isolated rat pancreases perfused in the presence of 8.3 mM d-glucose were compared with those of unesterified 2-deoxy-d-gl

The metabolism of β-l-glucose pentaacetate and its interference with the catabolism ofl-[U-14C]glutamine, [U-14C]palmitate,d-[U-14C]glucose, andd-[5-3H]glucose were examined in rat pancreatic islets. Likewise, attention was paid to the effects of th

The esterification of several monosaccharides, such as D-glucose, D-mannoheptulose and 2-deoxy-D-glucose was recently reported to increase their biological efficiency as either nutrient or antimetabolic agent. In the present study, however, the tetra

It was recently, and surprisingly, found that D-mannoheptulose did not affect D-glucose metabolism and insulinotropic action in pancreatic islets incubated at a low concentration of D-glucose. To explain this finding, the metabolism and secretory res
