WebMay 12, 2024 · FGF-23 is mainly produced by osteoblasts and osteocytes. Local expression of FGF-23 coreceptor (Klotho) is necessary for its function at the renal proximal tubules [ 27 ]. It inhibits renal Phos reabsorption through inhibitory effects on NaPi II a and II c at proximal renal tubules [ 28 ]. WebFGF-23 and Klotho “Phosphatonins” are circulating factors that regulate urinary Pi excretion. Two main phosphatonins have been described: FGF-23 and MEPE. Various forms of rickets have now all been found to be due to abnormalities in FGF-23.
