Calcitonin. Calcitonin is a 32 amino acid peptide hormone secreted by parafollicular cells (also known as C cells) of the thyroid (or endostyle) in humans and other chordates [5] in the ultimopharyngeal body. [6] It acts to reduce blood calcium (Ca 2+), opposing the effects of parathyroid hormone (PTH). [7]
Frequency. 15% (50 year olds), 70% (over 80 year olds) [7] Osteoporosis is a systemic skeletal disorder characterized by low bone mass, micro-architectural deterioration of bone tissue leading to more porous bone, and consequent increase in fracture risk. It is the most common reason for a broken bone among the elderly. [3]
InterPro. Calcitonin gene-related peptide (CGRP) is a member of the calcitonin family of peptides consisting of calcitonin, amylin, adrenomedullin, adrenomedullin 2 (intermedin) and calcitonin‑receptor‑stimulating peptide. Calcitonin is mainly produced by thyroid C cells whilst CGRP is secreted and stored in the nervous system. [1]
Calcitonin receptor. The calcitonin receptor (CT) is a G protein-coupled receptor that binds the peptide hormone calcitonin and is involved in maintenance of calcium homeostasis, [5] particularly with respect to bone formation and metabolism. [6][7][8]
Research shows that statins may benefit those over the age of 70, too. BSIP/Getty Images. Statins are a type of medication that can help lower a person’s “bad” cholesterol, helping reduce ...
Osteomalacia is the softening of bones due to poor bone mineralization which is in turn due to poor calcium absorption. [ 2] Ultimately, these hormonal changes in body; such as function of thyroid, parathyroid, liver and kidney disrupts metabolic changes as well as function of specific organs, which in turn leads to condition that are not ...
PubMed search. [3] [4] Wikidata. View/Edit Human. View/Edit Mouse. Parathyroid hormone (PTH), also called parathormone or parathyrin, is a peptide hormone secreted by the parathyroid glands that regulates the serum calcium concentration through its effects on bone, kidney, and intestine. [5] PTH influences bone remodeling, which is an ongoing ...
Calcitonin gene-related peptide (CGRP) receptor antagonists are a class of drugs that act as antagonists of the calcitonin gene-related peptide receptor (CGRPR). [1] Several monoclonal antibodies that bind to the CGRP receptor or peptide have been approved for prevention of migraine. [2] Nerve activation triggers the release of CGRP and other ...
