Calcitonin (CT) is a 32 amino acid peptide synthesised in mammals in a number of tissues, especially the C cells of the thyroid gland. CT was discovered because of its ability to lower the concentration of plasma calcium, an action principally due to a potent inhibitory action of CT on osteoclast-mediated bone resorption. CT is thus used clinically in the treatment of bone disorders characterised by increased rates of bone resorption, including Paget’s disease, osteoporosis and hypercalcemia…

The results are consistent with the hypothesis that CT-induced reduction in E-cadherin expression may remodel the adherens junctions between epithelial cells, and this change in epithelial cell phenotype might be a critical event during the implantation of the blastocyst.
