Endocytosis and Vacuolar Degradation of the Yeast Cell Surface Glucose Sensors Rgt2 and Snf3
J Biol Chem
Sensing and signaling the presence of extracellular glucose is crucial for the yeast Saccharomyces cerevisiae because of its fermentative metabolism, characterized by high glucose flux through glycolysis. The yeast senses glucose through the cell sur...

Dynamic modulation of intracellular glucose imaged in single cells using a FRET-based glucose nanosensor
Pflugers Arch
To study intracellular glucose homeostasis, the glucose nanosensor FLIPglu-600µM, which undergoes changes in fluorescence resonance energy transfer (FRET) upon interaction with glucose, was expressed in four mammalian cell lines: COS-7, CHO, HEK293,...

High glucose concentrations partially release hexokinase from inhibition by glucose 6-phosphate.
Proc Natl Acad Sci U S A
The phosphorylation of glucose by human erythrocyte hexokinase follows classical Michaelis-Menten kinetics; hexokinase manifests maximum activity at 5 mM glucose, and no further increase in activity can be measured at higher glucose concentrations. H...

Differential effects of oral, peripheral intravenous, and intraportal glucose on hepatic glucose uptake and insulin and glucagon extraction in conscious dogs.
J Clin Invest
The effect of equal (1.1 +/- 0.1 g/kg body wt) amounts of glucose administered orally, or by peripheral intravenous or intraportal infusion on hepatic glucose uptake and fractional hepatic extraction of insulin and glucagon was studied in conscious d...

Portal glucose infusion-glucose clamp measures hepatic influence on postprandial systemic glucose appearance as well as whole body glucose disposal
Am J Physiol Endocrinol Metab
The full impact of the liver, through both glucose production and uptake, on systemic glucose appearance cannot be readily studied in a classical glucose clamp because hepatic glucose metabolism is regulated not only by portal insulin and glucose lev...

Glucose area under the curve during oral glucose tolerance test as an index of glucose intolerance
Diabetol Int
HbA1c and fasting plasma glucose (FPG) levels are commonly recognized as diagnostic indices for diabetes and glucose intolerance. However, they are not sufficient for clear detection of glucose intolerance in the early stage unless an oral glucose to...

Quantifying intracellular glucose levels when yeast is grown in glucose media
Sci Rep
In Saccharomyces cerevisiae, intracellular glucose levels impact glucose transport and regulate carbon metabolism via various glucose sensors. To investigate mechanisms of glucose sensing, it is essential to know the intracellular glucose concentrati...

Mechanisms of Epinephrine-induced Glucose Intolerance in Normal Humans
J Clin Invest
To evaluate the role of the splanchnic bed in epinephrine-induced glucose intolerance, we selectively assessed the components of net splanchnic glucose balance, i.e., splanchnic glucose uptake and hepatic glucose production, and peripheral glucose up...

Glucose Uptake and Phosphorylation in Pseudomonas fluorescens
J Bacteriol
Pseudomonas fluorescens ATCC 13525 and a particulate glucose oxidase (d-glucose:oxygen oxidoreductase, EC 1.1.3.4) mutant of this organism, gox-7, were examined to determine if glucose oxidation via particulate glucose oxidase is a required first ste...

Metabolic handling of orally administered glucose in cirrhosis.
J Clin Invest
We used a dual-isotope method (oral [1-14C]glucose and intravenous [6-3H]glucose) to examine whether the oral glucose intolerance of cirrhosis is due to (a) a greater input of glucose into the systemic circulation (owing to a lower first-pass hepatic...

Utilization of Glucose in Heterotrophic Media by Thiobacillus intermedius
J Bacteriol
The growth yield of Thiobacillus intermedius is greater in glucose-yeast extract or glucose-casein hydrolysate broth than in comparable media without glucose. The quantity of glucose utilized in the glucose-supplemented media is much greater than the...
