WebThe present study was designed to investigate the direct effect of p53 on actin and the actin–GSN and actin–JMY complexes at different calcium concentrations in order to get insight into the actin rearrangement of stressed cells. Here we are modeling the role of the high cytoplasmic GSN or JMY level in model cells. 2. WebParathyroid 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 osteoclasts do not have a …
