Assays for the pancreatic hormone glucagon have typically been carried out using RIAs, but specificity has always been a problem, as the same amino acid sequence is present in other endogenous peptides in addition to glucagon, as discussed in the Introduction. Sensitivity (i.e. the smallest concentration of a substance that can be reliably measured) is also a prominent issue, as circulating concentrations are likely to be low, around 10 pmol/l or less (22). The relevant changes in glucagon secretion, resulting from changes in plasma glucose concentrations, are also modest with increases in response to hypoglycaemia ranging from 20 to 30 pmol/l, but even more challenging are decreases in response to hyperglycaemia, which may lower the concentrations to 1-2 pmol/l (24). Clearly, assays with sensitivities ,5 pmol/l are, therefore, unsuitable for the complete characterisation of glucagon secretion. The present study demonstrates that it is important to test a commercial assay carefully before being ...

OBJECTIVE Oxyntomodulin (OXM) is a glucagon-like peptide 1 (GLP-1) receptor (GLP1R)/glucagon receptor (GCGR) dual agonist peptide that reduces body weight in obese subjects through increased energy expenditure and decreased energy intake. The metabolic effects of OXM have been attributed primarily to GLP1R agonism. We examined whether a long acting GLP1R/GCGR dual agonist peptide exerts metabolic effects in diet-induced obese mice that are distinct from those obtained with a GLP1R-selective agonist.. RESEARCH DESIGN AND METHODS We developed a protease-resistant dual GLP1R/GCGR agonist, DualAG, and a corresponding GLP1R-selective agonist, GLPAG, matched for GLP1R agonist potency and pharmacokinetics. The metabolic effects of these two peptides with respect to weight loss, caloric reduction, glucose control, and lipid lowering, were compared upon chronic dosing in diet-induced obese (DIO) mice. Acute studies in DIO mice revealed metabolic pathways that were modulated independent of weight loss. ...

The prevalence of obesity has been rapidly increasing worldwide over the last several decades and has become a major health problem in developed countries. The brain, especially the hypothalamus, plays a key role in the control of food intake by sensing metabolic signals from peripheral organs and modulating feeding behaviors. To accomplish these important roles, the hypothalamus communicates with other brain areas such as the brainstem and reward-related limbic pathways. The adipocyte-derived hormone leptin and pancreatic beta-cell-derived insulin inform adiposity to the hypothalamus. Gut hormones such as cholecystokinin, peptide YY, pancreatic polypeptide, glucagon-like peptide 1, and oxyntomodulin transfer satiety signals to the brain and ghrelin relays hunger signals. The endocannabinoid system and nutrients are also involved in the physiological regulation of food intake. In this article, we briefly review physiological mechanisms of appetite regulation. ...

AU - Wootten, Denise. AU - Simms, John. AU - Valant, Celine. AU - Miller, Laurence J. AU - Christopoulos, Arthur. AU - Sexton, Patrick. PY - 2011. Y1 - 2011. N2 - The glucagon-like peptide-1 receptor (GLP-1R) is a key physiological regulator of insulin secretion and a major therapeutic target for the treatment of diabetes. However, regulation of GLP-1R function is complex with multiple endogenous peptides that interact with the receptor, including full length (1-37) and truncated (7-37) forms of GLP-1 that can exist in an amidated form (GLP-1(1-36)NH(2) and GLP-1(7-36)NH(2)), and the related peptide oxyntomodulin. In addition, the GLP-1R possesses exogenous agonists, including exendin-4, and the allosteric modulator, compound 2 (6,7-dichloro2-methylsulfonyl-3-tert-butylaminoquinoxaline). The complexity of ...

Twice-daily injection of ICV administration of OXM for 7 days caused a reduction in daily food intake with no tachyphylaxis. Furthermore, there was a significant reduction in body weight gain that was associated with a decrease in adipose tissue. Animals were observed daily and showed no signs of illness or behavioral abnormality. In the pair-fed group, animals gained slightly less weight than control animals, although this was not statistically significant. However, the OXM-treated animals gained significantly less weight than either of the two control groups. Furthermore, the reduction in WAT and BAT observed after chronic ICV OXM administration was not observed in the pair-fed group. This is suggestive of OXM causing weight loss and reduced body adiposity by mechanisms additional to its effects on food intake.. It is known that, during fasting and chronic food restriction, the expression of prepro-TRH in the PVN is suppressed. This reduces the secretion of TSH from the pituitary, which, in ...

This study examined whether the densities of stem- and enteroendocrine cell progenitors are abnormal in the ileum of patients with irritable bowel syndrome (IBS), and whether any abnormalities in ileal enteroendocrine cells are correlated with abnormalities in stem cells and enteroendocrine cell progenitors. One hundred and one IBS patients covering all IBS subtypes were recruited, and 39 non-IBS subjects were included as a control group. The patients and controls underwent standard colonoscopies, during which biopsy specimens were obtained from the ileum. The biopsy specimens were stained with hematoxylin-eosin and immunostained for Musashi-1 (Msi-1), neurogenin 3 (NEUROG3), chromogranin A (CgA), serotonin, peptide YY (PYY), oxyntomodulin (enteroglucagon), pancreatic polypeptide, and somatostatin. The immunoreactive cells were quantified by computerized image analysis. The densities of Msi-1, NEUROG3, CgA, and serotonin cells were reduced in all IBS patients and in patients with diarrhea-predominant

Intraduodenal infusion of ricinoleic acid and iv bolus injection of the C-terminal octapeptide of cholecystokinin produce markedly similar alterations in the digestive contractile patterns of the GI tract of the unanesthetized dog. The brief, initial stimulation of contractile activity in the proximal small intestine following both procedures is mediated through a cholinergic mechanism. The stimulatory response is followed by an inhibition of digestive contractile activity of unknown origin. These observations suggest that possibility that the GI hormone, cholecystokinin, may mediate the intestinal motor response evoked by infusion of ricinoleic acid directly into the proximal small intestine.

Posted 09/30/2015 , By HealthCorps. Researchers have identified a number of appetite hormones that play a role in appetite regulation. Some names that you may or may not have heard of include: Amylin, CCK, Dopamine, Ghrelin, GIP, GLP-1, Glucagon, Insulin, Leptin, NPY, OXM, PP, PYY, Seotonin. Each hormone plays a specific role in appetite regulation, and in some cases, the appetite hormones work synergistically to respond to hunger cues. Studies suggest that cravings and hunger can occur when levels of some of these hormones are either too high or too low.. Use the following tips to help manage hunger, especially if youre trying to lose weight:. ...

Description: A modestly active, nonselective triarylimidazole lead was optimized for binding affinity with the human glucagon receptor. This led to the identification of a 2- and/or 4-alkyl or alkyloxy substituent on the imidazole C4-aryl group as a structural determinant for significant enhancement in binding with the glucagon receptor (e.g., 41, IC(50)=0.053 microM) and selectivity (>1000x) over p38MAP kinase in this class of compounds. ...

BioAssay record AID 293012 submitted by ChEMBL: Displacement of [125]glucagon from human glucagon receptor expressed in CHO cells.

On the basis of the amino acid sequence of bovine rhodopsin, a series of peptides from the C-terminus (Rhod-4 and Rhod-1) and external loops (Rhod-10) were synthesized. Rabbit antisera to these peptides recognize the rhodopsin molecule in whole retina from 8-week-old normal and affected rcdl (rod/cone-dysplasic) Irish setters (8- and 4-weeks-old). When the rhodopsin content was equalized by using a solid-phase radioimmunoassay, the reaction with anti-peptide antisera to the C-terminal octapeptide (residues 341-348) is severely decreased in the rcdl-dog retinas. The results of mixing experiments suggest that this is not due to proteolytic clipping of the rhodopsin C-terminus from the affected dogs. Treatment of retinas with 1.0 mM-NaF, a phosphatase inhibitor, or pretreatment with alkaline and acid phosphatases does alter the reaction of the rhodopsin with anti-rhodopsin antisera. This suggests that the decreased reaction of the affected rhodopsin with the anti-peptide antisera may partially ...

Hyaluronic acid (HA), a glycosaminoglycan in the extracellular matrix, binds to CD44 and Toll-like receptor 4 (TLR4). We previously demonstrated that both CD44 and TLR4, but predominately TLR4, mediated HA stimulation of Lgr5+ stem cell proliferation, crypt fission, and intestinal growth in postnatal mice. Here we address the questions of which cell type expresses the relevant TLR4 in driving intestinal growth and what are the downstream events from TLR4 activation. Studies were done in 14-day-old mice: wild type (WT), mice deficient in cyclooxygenase 2 (COX2), mice deficient in myeloid cell TLR4, and mice deficient in epithelial cell epidermal growth factor receptor (EGFR). Biological end points included crypt fission and Lgr5 cell proliferation. In WT mice, treatment with NS-398 (a COX2 inhibitor), clodronate (a macrophage-depleting agent), or tyrphostin (an EGFR inhibitor) resulted in 30% reductions in crypt fission and Lgr5+ stem cell proliferation compared with control mice. Mice deficient ...

The glucagon-like peptide 1 receptor (GLP1R) is a receptor protein found on beta cells of the pancreas. It is involved in the control of blood sugar level by enhancing insulin secretion. In humans it is synthesised by the gene GLP1R, which is present on chromosome 6. It is a member of the glucagon receptor family of G protein-coupled receptors. GLP1R is composed of two domains, one extracellular (ECD) that binds the C-terminal helix of GLP-1, and one transmembrane (TMD) domain that binds the N-terminal region of GLP-1. In the TMD domain there is fulcrum of polar residues that regulates the biased signaling of the receptor while the transmembrane helical boundaries and extracellular surface are a trigger for biased agonism. GLP1R binds glucagon-like peptide-1 (GLP1) and glucagon as its natural endogenous agonists. Receptor agonists: GLP-1 - endogenous in humans glucagon - endogenous in humans liraglutide exendin-4, lixisenatide Receptor antagonists: T-0632 Receptor positive allosteric ...

Anti-glucagon antibodies have shown some efficacy in animal models (Brand et al., 1994, 1996; Sørensen et al., 2006a); however, daily injections of high doses of antibodies were required (Sørensen et al., 2006). The lack of long-term efficacy of the antibody on blood glucose lowering is probably due to a compensatory mechanism involving oversecretion of endogenous glucagon in response to the reduction of glucagon receptor signaling. Increases in circulating glucagon levels have been reported with all modalities blocking the glucagon signaling pathway, which presents technical challenges for both small-molecule GCGR inhibitors and glucagon-neutralizing mAb approaches.. Despite rising glucagon levels, treatment with neutralizing hGCGR mAbs maintained glucose-lowering efficacy. These anti-GCGR mAbs have several desirable attributes as potential therapeutic agents compared with previously pursued approaches. First, mAb B showed a higher affinity than glucagon to the GCGR (Kd = 36 pM versus Kd = ...
