Calcitonin is a peptide hormone that lowers blood calcium level and inhibits bone resorption. It belongs to the calcitonin family of peptides, which also includes amylin , calcitonin gene-related peptide , and adrenomedullin. The binding of salmon calcitonin to the human calcitonin receptor (CTR) is not modulated by receptor activity-modifying proteins (RAMPs), which influence affinity of human calcitonin to CTR. Salmon calcitonin binds to human CTR2 with IC50 values of 0.933, 0.224, 0.134, and 0.317 nM alone and with RAMP1, 2, or 3, respectively. It induces cAMP accumulation in COS-7 cells transfected with CTR2 (EC50 = 0.166 nM). Salmon calcitonin inhibits bone resorption by osteoclasts in a pit formation assay using rat bone slices (ID50 = 0.003 pg mL) and lowers calcium level in vivo in a bioassay of hypocalcemia in rats (ED15 = 33.9 mg kg). Formulations containing salmon calcitonin have been used to treat hypercalcemia, bone destruction by osteoporosis, and Paget's disease.
Calcitonin,eel TFA is a thyroid hormone polypeptide that can regulate calcium homeostasis and is widely used in the study of postmenopausal osteoporosis.
Calcitonin, eel is a peptide hormone that plays a crucial role in maintaining calcium balance within the body. It is extensively utilized in the scientific investigation of postmenopausal osteoporosis, a condition characterized by decreased bone density and an increased risk of fractures in women after menopause.
Calcitonin Gene Related Peptide II is a potent, long-lasting vasodilator; activation of CGRP receptors on pancreatic β-cells increases plasma levels of pancreatic enzymes.
Calcitonin (8-32), salmon, is a highly selective amylin receptor antagonist. Calcitonin, a hormone involved in calcium and phosphorus metabolism, is primarily produced by the parafollicular or C cells in the thyroid gland of mammals.
Calcitonin Gene Related Peptide (CGRP) (83-119), rat is a 37 amino acid calcitonin family of neuropeptide, acts through calcitonin receptor-like receptor.
