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.
Calcitonin. Calcitonin is produced by the C cells of the thyroid gland and is released when levels of calcium in the blood are increased. Its role is to decrease the amount of calcium in the blood. It has the opposite action to parathyroid hormone, which increases the amount of calcium in the blood when levels fall.hen calcium levels are high, more calcitonin is released from the gland. When calcium levels fall, the release of calcitonin also falls. Some other hormones play a role in the regulation of calcitonin. Somatostatin is a hormone which reduces the release of calcitonin, and gastrin promotes the release of calcitonin.
