Inflammation leads to functional iron deficiency, by increasing the expression of hepatic regulatory peptide, hepcidin. also stimulates fibroblast growth factor 23 (FGF23) production both Fgf23 transcription and FGF23 cleavage, which paradoxically excess in C-terminal peptides (Cter-FGF23), rather than intact hormone (iFGF23). We determined that major source Cter-FGF23 are osteocytes investigated whether play a direct role regulation hepcidin metabolism response acute inflammation. Mice...

Fibroblast growth factor 23 (FGF23) is a phosphate (Pi)-regulating hormone produced by bone. Hereditary hypophosphatemic disorders are associated with FGF23 excess, impaired skeletal and osteomalacia. Blocking became an effective therapeutic strategy in X-linked hypophosphatemia, but testing remains limited autosomal recessive rickets (ARHR). This study investigates the effects of Pi repletion bone specific deletion Fgf23 on mineral metabolism Dmp1 knockout (Dmp1KO) mouse model ARHR.At 12...
