Phosphate homeostasis
WebThe kidney plays an essential role in maintaining phosphate homeostasis. High dietary phosphate for several days in healthy humans has been shown to increase intact fibroblast growth factor 23 (i-FGF23) and intact parathyroid hormone (i-PTH) and suppress 1,25-dihydroxyvitamin D (1,25VD) levels, leading to the elevation of urinary phosphate ... WebSep 10, 2024 · Physiologically, the maintenance of calcium and phosphorus homeostasis is achieved via a variety of concerted actions of hormones such as parathyroid hormone (PTH), vitamin D, and fibroblast growth factor (FGF23), which could be regulated mainly at three organs, the intestine, kidney, and bone.

WebPhosphate homeostasis The average healthy adult has approximately 25mol (680g) of phosphate; 85% is found in the skeleton, 10–15% in soft tissues and <1% in extra-cellular … WebSeveral hormones, including estrogen and adrenaline, also affect phosphorus homeostasis. When kidney function declines, as in chronic kidney failure, the body cannot excrete phosphate efficiently, and serum levels rise [ 9 ]. Although phosphorus status is not typically assessed, phosphate can be measured in both serum and plasma [ 10 ].

WebOverview of Phosphate Homeostasis. In healthy adults, the steady-state serum phosphorus concentration is determined by the balance between the intestinal absorption of phosphate from the diet, the storage and release of phosphate in bone, and the excretion of phosphate through the urine. The key hormonal regulators of phosphate metabolism ...
