| Research Abstract |
The phosphorus metabolic regulation is performed by the excretion from kidney, the absorption from intestinal tract, the exchange with bones, a balance of the transportation in the cell membrane. The main factor prescribing blood phosphorus concentrations is fixed by reabsorption by NaPi IIa of the lumen side of most proximal tubules by the phosphorus excretion from kidney. It is assumed that FGF-23 and OCIF : Osteoclast inhibitory factor/OPG : Osteoprotegerin) play the role that is important to clinical condition formation of the secondary hyperparathyroidism in the chronic renal failure. However, there are many any questions whether FGF-23 and OPG form PTH or 1α, 25(OH) 2D3 adjustment system and what kind of network. Therefore we determine molecular roles such as OPG in the chronic renal failure model mouse, FGF-23, klotho.
