Parathyroid hormone regulates serum calcium through its effects on bone, kidney, and the intestine: In bone, PTH enhances the release of calcium from the large reservoir contained in the bones. Bone resorption is the normal destruction of bone by osteoclasts, which are indirectly stimulated by PTH. Stimulation is indirect since osteoclast… WebMay 1, 2003 · PTH-related peptide (PTHrP) is the principal mediator in hypercalcemia associated with solid tumors. 6 PTHrP is homologous with PTH at the amino terminus, the region that comprises the...
