WebFGF23 expression and function in vivo. We previously showed that osteoblast/osteocyte–specific flox-Fgf23 recombination using Dmp1-Cre suppressed circulating bioactive, intact FGF23 (iFGF23) in mice with normal renal function (47). Importantly, this animal was resistant to increasing FGF23 following high-phosphate … WebJul 15, 2024 · Osteocytes also govern phosphate homeostasis through the production of fibroblast growth factor 23 (FGF23), which lowers serum phosphate levels by increasing renal phosphate excretion and reducing the synthesis of 1,25-dihydroxyvitamin D (1,25 (OH) 2 D), an active metabolite of vitamin D.

Frontiers Roles of osteocytes in phosphate metabolism

WebRecent studies have demonstrated that levels of fibroblast growth factor 23 (FGF-23), a key regulator of phosphorus and vitamin D metabolism, rise dramatically as renal function declines and may play a key initiating role in disordered mineral and bone metabolism in patients with chronic kidney disease (CKD).

WebFGF23 is primarily produced in bone by osteocytes and is a 32 kDa protein containing 251 amino acids (5). The N-terminus contains a FGF homology region which binds to the FGF receptor and the C-terminus binds to the co-receptor αKlotho, ultimately creating a FGF receptor complex necessary for signaling at the FGF receptor (6). WebMar 19, 2024 · Excessive fibroblast growth factor 23 promotes renal fibrosis in mice with type 2 cardiorenal syndrome. Lack of PTEN in osteocytes increases circulating phosphate concentrations by decreasing intact fibroblast growth factor 23 levels. Osteocyte Vegf-a contributes to myeloma-associated angiogenesis and is regulated by Fgf23.

WebDec 19, 2024 · X-linked hypophosphatemia (XLH) is the most common hereditary form of rickets and deficiency of renal tubular phosphate transport in humans. XLH is caused by the inactivation of mutations within the phosphate-regulating endopeptidase homolog X-linked (PHEX) gene and follows an X-dominant transmission. It has an estimated frequency of … WebOsteocytes therefore appear to sense Pi directly and this may be an important means, by which FGF23 production is regulated. The intriguing possibility is that the Pi response and 1,25D pathways interact in additional ways. 1,25D also modulates the expression of other genes related to phosphate handling in cells of the osteoblast lineage.
