Several reports demonstrate unexplained consequences of mutations on the expression of the different dystrophin isoforms and their balance. The most prominent example is found in some cases of X-linked dilated cardiomyopathy (XLDC).
In particular, calcitonin has the ability to decrease blood calcium levels at least in part by effects on two well-studied target organs: 1  Bone: Calcitonin suppresses resorption of bone by inhibiting the activity of osteoclasts, a cell type that digests bone matrix, releasing calcium and phosphorus into blood.
Introduction. Calcitonin is produced by the parafollicular C cells of the thyroid. This hormone is thought to function in calcium and phosphorous metabolism, essentially opposing the effects of parathyroid hormone.In addition, calcitonin represents the classical clinical marker for medullary thyroid carcinoma (MTC).n elevated serum calcitonin level is a highly sensitive marker for medullary thyroid carcinoma (MTC) that can be used for screening, differential diagnosis, prognostic assessment, follow-up monitoring, and assessment of treatment response.
