Endocrinology/Hormones

<p>Natural cleavage product of GLP-1 which, unlike GLP-1, does not affect either insulin secretion or glucose homeostasis.  GLP-1(9-36) has low affinity for, and acts as an antagonist to, the GLP-1 receptor.GLP-1 (9-36) does however display unique biological activities such as beneficial cardiovascular effects and reducing the production of reactive oxygen species (ROS). GLP-1 (9-36) also exerts important physiological effects on neuronal plasticity in the hippocampus, and inhibits chemokine-induced migration of human CD4-positive lymphocytes.GLP-1 (9-36) is formed from the breakdown of biologically active but highly unstable GLP-1 (7-36) amide by the ubiquitous serine protease, dipeptidyl peptidase-IV (DPP-IV).</p>

<p>A Chemerin-9 peptide derived from chemerin, a protein that is involved in a variety of functions such as autocrine, angiogenic, reproductive and chemotactic processes. Chemerin-9 binds to the chemerin receptor 23 (G-protein coupled receptor) and causes the receptors internalisation.</p>

PTH 13-34 is a biologically active fragment of parathyroid hormone (PTH) with hypertensive activities. PTH 13-34 is being trialled as a possible treatment for osteoporosis (to replace the existing recombinant human PTH 1-34 treatment peptide).PTH is an 84-amino-acid polypeptide hormone (PTH 1-84) which is secreted by the parathyroid glands along with its fragments (such as PTH 1-34 and PTH 7-84). PTH increases calcium and decrease phosphate levels in the blood and the abundance of PTH-derived peptides is regulated by blood calcium levels. PTH inhibits the bone growth-promoting activity of osteoblasts and induces osteoclasts to resorb bone and release calcium and phosphate ions into the blood. PTH binds to and activates the receptor parathyroid hormone receptor 1 (PTHR1). PTHR1 is a G-protein-coupled receptor (GPCR) which regulates mineral ion homeostasis, bone turnover and skeletal development.

<p>Originally identified in Heloderma horridum horridum (Mexican beaded lizard), exendin-3 shares homology with vasoactive intestinal peptide (VIP), secretin, helospectin I and II and helodermin. Exendin-3 increases cellular cAMP levels and amylase release from pig pancreatic cells.Truncated exendin-3 is a potent and selective GLP-1 receptor antagonist. It inhibits cAMP production and insulin release induced by GLP-1, exendin-3, and exendin-4. It also blocks the inhibitory effect of GLP-1 on food intake in rats. Exendin 3 (9-39) amide is being considered for clinical use in obese patients. This is based on the extensive and consistent data demonstrating its effectiveness as a tool to improve fasting and postprandial levels of glucose and glucagon.</p>

<p>Glucagon like-peptide-2 (GLP-2) is a gut hormone produced in the enteroendocrine L cells of gastrointestinal tract by the cleavage of the 160-amino-acid proglucagon molecule. GLP-2 is secreted following the ingestion of food and carries out its activities via the GLP-2 G-protein coupled receptors (GLP-2Rs). GLP-2 has a range of roles within the cell, including: anti-inflammatory effects promoting the expansion of the intestinal mucosa, stimulating intestinal blood flow, inhibiting gastric acid secretion and gastric emptying, increasing intestinal barrier function and enhancing nutrient and fluid absorption.</p>

<p>Bradykinins and their associated kinins are inflammatory mediators produced during inflammation. The two main kinins in mammals are the nonapeptide bradykinin, BK (1-9) and the decapeptide kallidin (KD), [Lys0]-BK(1-10). Their biological actions are mediated by two distinct receptors, termed B1 and B2.-BK is involved in several pathophysiological processes, such as inflammation, pain, cell proliferation, and tumours. It plays a crucial role in corneal epithelial cells, corneal stromal cells, and fibroblasts.Inflammation has been reported as one significant hallmark of breast cancer in relation to tumour development, metastasis, and invasion. The bradykinin receptor 1 (B1R) associated with kallidin is highly expressed on inflammatory breast tumour cells thus providing a promising targeting site for tumour recognition and sufficient receptor mediated endocytosis.</p>

<p>ANP (7-20) is derived from the atrial natriuretic peptide (ANP) which is a cardiac hormone involved in maintaining cardio-renal homeostasis. This occurs through the activation of the guanylyl cyclase-coupled receptor, resulting in the increased concentration of cyclic guanylate monophosphate. Moreover its function in the processes of anti-proliferation and anti-angiogenesis allow it to take part in the cardiovascular remodelling process.ANP is a member of the natriuretic peptide family and it is encoded by the NPPA gene, located on chromosome 1. Once synthesized from the 151 amino acid pre-prohormone into its biologically active form, ANP is secreted by the atrial cardiomyocytes in the circulating forms: ANP (1-98) and ANP (99-126). This synthesis process involves the signal peptide being removed from the pre-prohormone resulting in proANP (1-126) which is converted into the circulating forms by the type II transmembrane serine protease Corin.</p>

<p>Residues 1-12 of the gastrointestinal hormone motilin, secreted from endocrine cells in the small intestines, mainly from the jejunum and duodenum, in response to the fasting, drinking water or the mechanical stimulus of eating.</p>

<p>ANP (7-23) is derived from the atrial natriuretic peptide (ANP) which is a cardiac hormone involved in maintaining cardio-renal homeostasis.

<p>This is an incretin hormone that causes glucose dependent release of insulin by pancreatic beta cells. It is the cleavage product of GLP-1 (1-36) amide peptide.  This peptide, human GLP-1 (7–36), shares the same sequence with preproglucagon (78-107), amide, human.</p>

<p>Glucagon-like peptide (GLP) 1 is a post-translationally modified version of proglucagon. GLP-1 (1-37) is a naturally produced analog of GLP-1. Unlike truncated GLP-1, GLP-1 (1-37) does not alter food intake in rat models or pancreatic insulin secretion. GLP-1 (1-37) can induce insulin production in developing adult intestinal cells via upregulation of the ngn3 gene and its downstream targets. This can restore glucose homeostasis when implanted into diabetic mice. GLP-1 (1-37) may offer a  future treatment for diabetes mellitus. GLP-1 (1-37) can also inhibit chemokine-induced migration of human CD4-positive lymphocytes, an early step in atherogenesis. This raises the possibility that GLP-1 (1-37) is part of a novel mechanism to modulate vascular disease.</p>

<p>GPS1573 is a potent and dose-dependent peptide antagonist of adrenocorticotrophic (ACTH) -stimulated melanocortin type 2 receptor (MC2R). Along with GPS1574, GPS1773 is an ACTH analogue and as such antagonises MC2R in the nanomolar range.The clinical relevance of GPS1573 is related to Cushing's disease and syndrome, which are both associated with a hypercortisolemic state. Selective antagonism of MC2R using GPS1573 may be a novel treatment modality for Cushing's disease and syndrome.</p>
