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 is the other major hormone involved with calcium regulation. Parathyroid hormone (PTH), produced by the parathyroid gland, increases the level of calcium in the blo â¦ od. It usually accomplishes this by increasing the resorption rate (taking back) from bone.Calcitonin does the exact opposite and reduces calcium in the blood.arathyroid hormone (PTH) and calcitonin regulate blood calcium levels. PTH increases the calcium concentration in the blood, and calcitonin decreases it. 2 people found this useful. Edit.
