Abstract
Glucagon-like peptide-1 (GLP-1), a future treatment for type 2 diabetes, is efficiently degraded by the enzyme dipeptidyl peptidase IV (DPP IV), yielding the major metabolite GLP-1-(9-36)-amide. In this study, we examined the potential glucose lowering effect of GLP-1(9-36)-amide in mice and found that GLP-1-(9-36)-amide (3 and 10 nmol/kg) did not affect insulin secretion or glucose elimination when administered intravenously together with glucose (1 g/kg). This was observed both in normal mice and in transgenic mice having a complete disruption of the signalling from the GLP-1 receptor. Furthermore, after blocking insulin secretion, using diazoxide (25 mg/kg), no effect on insulin-independent glucose disposal of GLP-1-(9-36)-amide was... (More)

Furthermore, after blocking insulin secretion, using diazoxide (25 mg/kg), no effect on insulin-independent glucose disposal of GLP-1-(9-36)-amide was observed. Therefore, GLP-1-(9-36)-amide does not affect glucose disposal in mice either in the presence or absence of intact GLP-1-receptors or in the presence or absence of stimulated insulin levels. This suggests that the GLP-1 metabolite is not involved in the regulation of glucose homeostasis. (C) 2004 Elsevier B.V. All rights reserved. (Less)
