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

Figure 8 Influence of β-adrenoreceptors antagonists on hexose uptake in rat adipocytes. Rat fat cells were incubated for 45 min with the indicated concentrations of agents without (control, closed columns), and with 0.1 mmol/L bupranolol (shaded columns), 0.1 mmol/L propranolol (grey columns) or 0.1 mmol/L CGP 20712 (open columns) prior to 2-deoxyglucose uptake, expressed as the fold increase relative to basal. The mean ± SE of 4 separate experiments performed in the presence of 100 µmol/L vanadate was determined. Significant difference between the inhibitor and the respective control was observed at: ^aP < 0.05. 2-DG: 2-Deoxyglucose.
