Disordered FGF23 and mineral metabolism in children with CKD.
BACKGROUND AND OBJECTIVES In children with CKD, information is limited regarding the prevalence and determinants of fibroblast growth factor 23 excess and 1,25-dihyroxyvitamin D deficiency across the spectrum of predialysis CKD. This study characterized circulating concentrations of fibroblast growth factor 23 and 1,25-dihyroxyvitamin D, and investigated their interrelationships and association...
متن کاملFGF23 and mineral metabolism, implications in CKD-MBD.
Correspondence: Mariano Rodríguez Servicio de Nefrología. Hospital Universitario Reina Sofía. REDINREN, IM IBIC, Córdoba. [email protected] The regulation of mineral metabolism is achieved trough a complex interaction of hormonal factors and target organs. Before the discovery of FGF23 we believed that the regulation of serum calcium and phosphate was mainly the result of...
متن کاملFGF23-Klotho axis in CKD
Fibroblast growth factor 23 (FGF23) is a bone-derived hormone regulating phosphate and vitamin D metabolism. FGF23 works by binding to Klotho-FGF receptor (FGFR) complex. FGF23 reduces serum phosphate level by suppressing the expression of type 2a and 2c sodium-phosphate cotransporters in the renal proximal tubules. In addition, FGF23 suppresses intestinal phosphate absorption by reducing 1,25-...
متن کاملEvaluation of the Role of FGF23 in Mineral Metabolism
Fibroblast growth factor 23 (FGF23) has recently been identified as a critical regulatory factor in phosphate (P) metabolism. Although the exact molecular mechanism of FGF23 synthesis through sensing the concentration of P is yet to be determined, experimental and clinical data indicate the influential role of FGF23 in P and calcium (Ca) homeostasis. Here, we extended our previous mathematical ...
متن کاملFGF23: a key player in mineral and bone disorder in CKD.
FGF23 is a recently identified hormone regulating mineral and vitamin D metabolism. In patients with chronic kidney disease (CKD), circulating FGF23 levels are progressively elevated to compensate for persistent phosphate retention, which result in reduced renal production of 1,25-dihydroxyvitamin D and thereby stimulate secretion of parathyroid hormone, suggesting its critical role in the path...
