Vanadium-dependent activation of glucose transport in adipocytes by catecholamines is not mediated via adrenoceptor stimulation or monoamine oxidase activity

Figure 5 Effects of α- and β-adrenergic agonists on glucose transport in rat adipocytes. 2-Deoxyglucose uptake assay was performed as in Figure 3 with 100 µmol/L vanadate (orange arrows) and increasing doses of the indicated α- (left panel) or β-adrenergic agonists (right panel). Glucose transport was expressed as the fold increase relative to basal uptake (bas) set at 1.0. The mean ± SE of 4-6 adipocyte preparations was determined. Only high doses of isoprenaline and dobutamine induced responses were significantly different from baseline at: ^aP < 0.05. 2-DG: 2-Deoxyglucose.
