Calcitonins are 32-amino acid peptide hormones with both peripheral and central actions mediated via specific cell surface receptors, which belong to the class II subfamily of G protein-coupled receptors. Understanding receptor function, particularly in terms of ligand recognition by calcitonin receptors, may aid in the rational design of calcitonin analogs with increased potency and improved s...
Abstract Background The topical inflammatory soup can model the inflammation of dura mater causing hypersensitivity and activation trigeminal system, a phenomenon present in migraineurs. Calcitonin gene-related peptide, transient receptor potential vanilloid-1 receptor, neuronal nitric oxide synthase are important sensitization process there. 5-HT 1B/1D agonists, triptans used as treatment migr...
introduction: in order to develop a radiolabeled calcitonin (ct) derivative for receptor imaging studies, ct was successively labeled with 67ga-gallium chloride. methods: the best results of the conjugation were obtained by the addition of 0.5 ml of a ct nasal pharmaceutical solution (1100 iu) to a glass tube pre-coated with dtpa-dianhydride (0.01 mg) at 25°c with continuous mild stirring for 3...
BACKGROUND The polypeptide hormone calcitonin is clinically well known for its ability to relieve neuropathic pain such as spinal canal stenosis, diabetic neuropathy and complex regional pain syndrome. Mechanisms for its analgesic effect, however, remain unclear. Here we investigated the mechanism of anti-hyperalgesic action of calcitonin in a neuropathic pain model in rats. RESULTS Subcutane...
Calcitonin-family receptors comprise calcitonin receptor-like receptor (CL) or calcitonin receptor and receptor activity-modifying protein (RAMP) pairings. Calcitonin gene-related peptide (CGRP) receptors are CL/RAMP1, whereas adrenomedullin (AM) receptors are CL/RAMP2 (AM1 receptor) or CL/RAMP3 (AM2 receptor). Amylin (Amy) receptors are RAMP hetero-oligomers with the calcitonin receptor (AMY1,...
Calcitonin may induce cyclic AMP production by breast cancer cells and inhibit their growth. The molecular complex leading to cyclic AMP production in response to calcitonin is made of the calcitonin receptor coupled to the adenylate cyclase by at least one guanine nucleotide-binding protein (G-protein, of the Gs type). Our aim was to determine whether and how the responses of cells to calciton...
Calcitonin secretion in the pregnant uterus is tightly regulated by the ovarian hormones, estrogen and progesterone, which limit its expression to a brief period preceding blastocyst implantation. The binding of calcitonin to a G protein-coupled receptor activates adenylate cyclase and elevates cytosolic Ca2+ levels. The acceleration of preimplantation embryonic development that is known to occ...
Liraglutide is a glucagon-like peptide-1 (GLP-1) analog developed for type 2 diabetes. Long-term liraglutide exposure in rodents was associated with thyroid C-cell hyperplasia and tumors. Here, we report data supporting a GLP-1 receptor-mediated mechanism for these changes in rodents. The GLP-1 receptor was localized to rodent C-cells. GLP-1 receptor agonists stimulated calcitonin release, up-r...
