Behavioral, neuroendocrine, and autonomic responses to glucoprivation are impaired after a glucoprivic episode. A life-threatening manifestation of this effect, known as hypoglycemia-associated autonomic failure (HAAF), occurs in diabetic patients as a result of prior inadvertent hypoglycemia resulting from insulin therapy. Glucocorticoids, which are elevated by glucoprivation, have been implic...

Insulin-induced hypoglycemia by unknown mechanism(s) increases plasma arginine vasopressin (AVP) levels in humans. Mechanisms for increased AVP levels during central nervous system glucoprivation were investigated by administering 20-min i.v. infusions of 2-deoxy-d-glucose (50 mg/kg), a competitive inhibitor of glucose utilization, or normal saline (sham), to 24 normal volunteers. Some of the i...

Metabolic energy preferentially produced by glycolysis was an advantageous metabolic phenotype of cancer cells. It is also an essential contributor to the progression of multidrug resistance in cancer cells. By developing human breast cancer MCF-7 cells resistant to doxorubicin (DOX) (MCF-7/MDR cells), the effects and mechanisms of 2-deoxy-D-glucose (2DG), a glucose analogue, on reversing multi...

Glucose injections attenuate deficits in memory under several conditions in both rodents and humans. The present study examined effects of glucose on memory in two such amnesic populations, scopolamine-treated and old mice, and then assessed effects of glucose on brain (lHJ2deoxyglucose (2DG) uptake. In Experiment lA, scopolamine (3 mg/kg, i.p.) significantly impaired performance of mice tested...

OBJECTIVE To evaluate the acute toxicity of 2-deoxy-D-glucose (2DG) by oral (p.o.) and intravenous (i.v.) routes, and also the cardio-respiratory effects following high doses of 2DG in animal models. METHODS The LD50 of 2DG (in water) was determined in rats and mice by p.o. route and in mice by i.v. route. The effect of 2-DG (250 mg/kg, 500 mg/kg, and 1000 mg/kg, i.v.) was studied on various ...

Background: Both mitochondrial dysfunction and aerobic glycolysis are signs of growing aggressive cancer. If altered metabolism of cancer cell is intended, using the glycolysis inhibitor (2-deoxyglucose (2DG)) would be a viable therapeutic method. The AMP-activated protein kinase (AMPK), as a metabolic sensor, could be activated with metformin and it can also launch a p53-dependent metabolic ch...

Abstract Circulating nonadherent monocytes can migrate to extravascular sites by a process that involves adherence. Alterations in intracellular metabolism shape the immunological phenotype of phagocytes upon activation. To determine effect adherence on their metabolic and functional response human were stimulated with LPS under adherent conditions. Adherent (relative monocytes) produced less T...

A glucose analog, 2-deoxy-d-glucose (2DG), previously shown in swine to induce many of the hallmark parameters of stress, was administered to Salmonella choleraesuis carrier-swine and the effects on Salmonella fecal shedding and tissue colonization were evaluated. Initially, pigs were divided into two groups, one that received 1 x 10 (6) S. choleraesuis and one group that received saline. At 3 ...

A Cell paper by Montel-Hagen et al. (2008) published last year addresses the comparative physiology of ascorbate recycling in erythrocytes (Montel-Hagen et al., 2008). The authors claim in this paper that GLUT1-mediated glucose transport decreases whereas GLUT1-mediated dehydroascorbate (DHA) transport increases during erythropoi-esis despite markedly enhanced GLUT1 expression. To support these...
