Aims: We investigate the influence of GIP on ghrelin secretion in normal glucose tolerant individuals with the use of the firstly applied correlation network analysis on human plasma metabolome data.Methods: To address this issue, we employed a GIP-infusion test and euglycemic- and hyperglycemic glucose clamp experiments combined with infusion of GIP or placebo in a cross-over manner in non diabetic obese male subjects (n=14). Moreover, we firstly...

Introduction: Insulin resistance (IR), a pathological state of low sensitivity to insulin in humans and animlas, is closely associated with type 2 diabetes mellitus, obesity and cardiovasculare dieseas. IR can be quantified using detailed protocols, such as the euglycemic-hyperinsulinemic clamp (EC) technique and the intravenous glucose tolerance test, or based on indices derived from the oral glucose tolerance test. Although these indices showed greater association with the i...

Aims: Elevated levels of neurotensin (NT), a neurotransmitter and postprandial secreted intestinal hormone, are associated with an increased risk of diabetes, cardiovascular disease and breast cancer. Here we studied the regulation of circulating pro-NT (a stable NT precursor fragment) by weight loss and dietary interventions.Methods: DiOGenes is a pan-European controlled dietary intervention study in overweight adults who first lost body weight on an 8-...
