Usage
For Research Use Only. Not for use in diagnostic or therapeutic procedures.
Regulator of phosphate homeostasis. Inhibits renal tubular phosphate transport by reducing SLC34A1 levels. Regulator of vitamin-D metabolism. Negatively regulates osteoblasts differentiation and matrix mineralization. Acts directly on the parathyroid to decrease PTH secretion. Upregulates EGR1 expression in the presence of KL.

Increases in plasma erythropoietin and erythropoietin receptor activation are mechanisms implicated in the increase of plasma FGF23 in acute kidney injury.PMID:29395333
In chronic kidney disease (CKD) rat models, FGF23 mRNA is expressed in the kidney, and the FGF23 protein is expressed at high levels in osteopontin-positive renal tubule epithelium cells likely via TGFbeta1 stimulation. FGF23 produced in the kidney might contribute to P metabolism in subjects with CKD.PMID:29518087
High FGF23 expression is associated with cardiac hypertrophy.PMID:28339837
The only direct contribution of the injured kidney to circulating FGF23 levels in uremia appears to be reduced renal extraction of bone-derived FGF23.PMID:28341272
Osteoblast Fgf23 transcription is upregulated by increase in the cytosolic Ca(2+) activity. Fgf23 transcription is decreased by Orai inhibitors and Orai1 silencing. Fgf23 transcription is lowered by NFkappaB inhibitors.PMID:26631141

In non-iron depleted normal and uremic rats a single high dose of either of two intravenous iron preparations, iron isomaltoside 1000, and ferric carboxymaltose, had no effect on plasma levels of iFGF23 and phosphate for up to seven days.PMID:24373521

Serum FGF23 increased in uremic rats treated with paricalcitol but not those treated with cinacalcet.PMID:20200094
because of a downregulation of the Klotho-FGFR1c receptor complex, an increase of circulating FGF23 does not decrease parathyroid hormone levels in established chronic kidney disease.PMID:20016468
Data indicate that cleavage at the RXXR motif abrogates FGF23 activity by removing the binding site for the binary FGFR-Klotho complex in the C-terminal region of FGF23, and by generating an endogenous inhibitor of FGF23.PMID:19966287
a feedback loop exists among serum phosphorus, 1alpha,25(OH)(2)D(3), and FGF-23, in which the novel phosphate-regulating bone-kidney axis integrated with the parathyroid hormone-vitamin D(3) axis in regulating phosphate homeostasisPMID:15531762
