A physiological role in satiety is proposed for glucagon-like peptide-1 (GLP-1), secreted by the distal intestine in response to ingested nutrients. Here we report that in rats, ip injection of the GLP-1 receptor (GLP-1-R) antagonist exendin 9-39 (Ex9) elicited hyperphagia, but only at times of day when intake is otherwise low. Furthermore, ip administration of Ex9 attenuated satiety induced by...
BACKGROUND The glucagon-like peptide 1 receptor (GLP-1R) is believed to mediate glucoregulatory and cardiovascular effects of the incretin hormone GLP-1(7-36) (GLP-1), which is rapidly degraded by dipeptidyl peptidase-4 (DPP-4) to GLP-1(9-36), a truncated metabolite generally thought to be inactive. Novel drugs for the treatment of diabetes include analogues of GLP-1 and inhibitors of DPP-4; ho...
Aim To explore the effects of second-line combination therapies with metformin on body weight, HbA1c and health-related quality life, as well risks hypoglycaemia further treatment intensification in DISCOVER study, a 3-year, prospective, global observational study patients type 2 diabetes initiating glucose-lowering therapy. Materials Methods Adjusted changes from baseline 36-item Short Form He...
The incretin hormone, glucagon-like peptide 1 (GLP-1), regulates gastric emptying, glucose-dependent stimulation of insulin secretion and glucagon release, and GLP-1 analogs are therefore approved for treatment of type II diabetes. GLP-1 receptors are expressed in reward-related areas such as the ventral tegmental area and nucleus accumbens, and GLP-1 was recently shown to regulate several alco...
AIMS To characterize the pharmacology of MEDI0382, a peptide dual agonist of glucagon-like peptide-1 (GLP-1) and glucagon receptors. MATERIALS AND METHODS MEDI0382 was evaluated in vitro for its ability to stimulate cAMP accumulation in cell lines expressing transfected recombinant or endogenous GLP-1 or glucagon receptors, to potentiate glucose-stimulated insulin secretion (GSIS) in pancreat...
GLP-1-induced insulin secretion from the β-cell is dependent upon glucose availability. The purpose of the current study was to determine whether CNS GLP-1 signaling is also glucose-dependent. We found that fasting blunted the ability of 3(rd) cerebroventricularly (i3vt)-administered GLP-1 to reduce food intake. However, fasted animals maintained the anorexic response to melanotan II, a melanoc...
The pharmacological treatment of type 2 diabetes (T2DM) is becoming increasingly complex, especially since the availability of incretin-based therapies. Compared with other glucose-lowering strategies, these novel drugs offer some advantages such as an absence of weight gain and a negligible risk of hypoglycaemia and, possibly, better cardiovascular and β-cell protection. The physician has now ...
Dyslipidemia is a prominent feature of insulin resistance and type 2 diabetes mellitus, playing an important role in the etiology of cardiovascular disease in these conditions. An important component of the typical dyslipidemia of type 2 diabetes mellitus is elevated triglycerides (TG). We and others have demonstrated in animal models that, in insulinresistant states, triglyceride-rich lipoprot...
The number of pro-α cells is known to increase in response to β cell injury and these cells then generate glucagon-like peptide-1 (GLP-1), thus attenuating the development of diabetes. The aim of the present study was to further examine the role and the mechanisms responsible for intra-islet GLP-1 production as a self-protective response against lipotoxicity. The levels of the key enzyme, proho...
