Escherichia coli strain 15 (ATCC 9723), which forms robust biofilms, was grown under optimal biofilm conditions in NaCl-free Luria-Bertani broth (LB*) or in LB* supplemented with one of the non-metabolizable analogues 2-deoxy-d-glucose (2DG), methyl α-d-mannopyranoside (αMM), or methyl α-d-glucopyranoside (αMG). Biofilm growth was inhibited by mannose analogue 2DG even at very low concentration...

The secondary EGF receptor (EGFR) T790M is the most common mechanism of resistance to reversible EGFR-tyrosine kinase inhibitors (TKI) in patients with non-small cell lung cancer (NSCLC) with activating EGFR mutations. Although afatinib (BIBW2992), a second-generation irreversible EGFR-TKI, was expected to overcome the acquired resistance, it showed limited efficacy in a recent phase III clinic...

Insulin receptor substrate-2-deficient (IRS2(-/-)) mice develop type 2 diabetes. The purpose of this study was to determine whether there is a defect in basal, insulin-, and exercise-stimulated glucose transport in the skeletal muscle of these animals. IRS2(-/-) and wild-type (WT) mice (male, 8-10 weeks) exercised on a treadmill for 1 h or remained sedentary. 2-Deoxyglucose (2DG) uptake was mea...

Thorpe, A. J., J. A. Teske, and C. M. Kotz. Orexin A-induced feeding is augmented by caloric challenge. Am J Physiol Regul Integr Comp Physiol 289: R367–R372, 2005; doi:10.1152/ajpregu.00737.2004.— Orexin neurons are stimulated by conditions that are glucoprivic, suggesting that orexin signaling may be increased during nutritional duress. We have previously shown that injection of orexin A (OxA...

Pharmacological reduction of glucose availability with 2-deoxyglucose (2DG) suppresses pulsatile luteinizing hormone (LH) secretion in rats and growth-retarded lambs. Gonadal steroids enhance the glucoprivic suppression of LH secretion in rats. The present study determined if corticotropin-releasing hormone (CRH) plays a role in mediating oestrogen-dependent and -independent glucoprivic suppres...

Doxorubicin (DOX) was introduced as an effective chemotherapeutic for a wide range of cancers but with some severe side effects especially on myocardia. 2-Deoxy-D-glucose (2DG) enhances the damage caused by chemotherapeutics and ionizing radiation (IR) selectively in cancer cells. We have studied the effects of 1μM DOX and 500 μM 2DG on radiation induced cell death, apoptosis and also on the ex...

Gold nanoparticles are predominantly used in diagnostics, therapeutics and biomedical applications. The present study has been designed to synthesize differently capped gold nanoparticles (AuNps) by a simple, one-step, room temperature procedure and to evaluate the potential of these AuNps for biomedical applications. The AuNps are capped with glucose, 2-deoxy-D-glucose (2DG) and citrate using ...

Drought compromises edible vegetable production worldwide, including common bean (Phaseolus vulgaris L.) an economically important crop that is highly dependent on optimum rainfall or abundant irrigation. In the present study, phenotypic data of 26 Bulgarian mutant lines and cultivars subjected to drought stress has been summarized, reaction was evaluated by chlorophyll fluorescence proteomics ...

Inhibition of glycolysis using 2-deoxy-d-glucose (2DG, 20mM, 24-48h) combined with inhibition of the pentose cycle using dehydroepiandrosterone (DHEA, 300µM, 24-48h) increased clonogenic cell killing in both human prostate (PC-3 and DU145) and human breast (MDA-MB231) cancer cells via a mechanism involving thiol-mediated oxidative stress. Surprisingly, when 2DG+DHEA treatment was combined with ...
