Background: Glucose-dependent insulinotropic polypeptide (GIP) is a gastrointestinal hormone that is secreted in response to food intake. GIP acts on various tissues, including pancreatic ß-cells, via interaction with its G-protein-coupled receptor. Some studies in rodents suggested that GIP directly links overnutrition to obesity. GIP exerts a physiological role on lipid uptake into adipocytes.Objectives: To analyse the effect of GIP-Infusions on c...

Background: Glucose-dependent insulinotropic polypeptide (GIP) is a gastrointestinal hormone that is secreted in response to food intake and modulates β-cell function. Remarkably, GIP looses its insulinomimetic effect in the presence of chronic hyperglycaemia and thus appears to be ineffective in poorly controlled T2DM at least with regard to insulin release. The mechanism by which this occurs is not clear and it is not known.Objectives: To analyse ...

The diabetic epidemic is increasing worldwide. The suppressor of cytokine signaling 3 (SOCS3) provides a link between cytokine action and their negative consequences on insulin signaling. This potential influence on the development of T2DM makes the gene a potential candidate gene for type 2 diabetes.We investigated the one haplotype tagging single nucleotide polymorphism (htSNP) rs4969168 to examine the impact on T2DM in two independent study population...

Objectives: Premature estrogen deficiency and menopause are associated with increases in body weight and fat mass. Ovariectomized (OVX) mice also show reduced locomotor activity. Because glucose-dependent-insulinotropic-polypeptide (GIP) is known to play an important role both in fat metabolism and locomotor activity, we hypothesized that effects of estrogen on the regulation of body weight, fat mass and spontaneous physical activity could be mediated in part by GIP signaling....

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-...
