| pubmed-article:1953793 | pubmed:abstractText | The effect of islet amyloid polypeptide (IAPP/amylin) on 2-deoxyglucose (2-DG) uptake was studied in isolated mouse pancreatic acini in the absence or presence of insulin. Synthetic rat IAPP-NH2 caused a dose-dependent stimulation of 2-DG uptake by mouse acini with a half-maximal concentration at 70 nM. The increase in 2-DG uptake by 1 microM IAPP-NH2 or 100 nM insulin was 68% or 60% above basal, respectively. In the presence of both 1 microM IAPP-NH2 and 100 nM insulin, the increase in 2-DG uptake was 145% above basal, indicating that the effects of IAPP-NH2 and insulin on 2-DG uptake were additive. The results suggest that IAPP stimulates glucose uptake in mouse acini probably by a different mechanism from that of insulin. | lld:pubmed |
