Phosphate-sensing and regulatory mechanism of FGF23 production

Takashi, Y., Fukumoto, S.·2020·Journal of Endocrinological Investigation

Abstract

Background Inorganic phosphate (Pi) is an essential mineral for human. Hypophosphatemia and hyperphosphatemia cause rickets/osteomalacia and ectopic calcification, respectively, indicating that serum Pi level needs to be regulated. Fibroblast growth factor (FGF) 23 is a principal hormone to regulate serum Pi level. FGF23 is produced by the bone, especially by the osteoblasts and osteocytes, and works by binding to FGF receptor (FGFR) 1c and α-Klotho complex in the kidney. FGF23 reduces serum Pi level by inhibiting both renal phosphate reabsorption and intestinal phosphate absorption via reduction of serum 1,25-dihydroxyvitamin D level. It has been unclear how the bone senses changes of serum Pi level and how the bone regulates the production of FGF23.Recent findings Our recent results indicate that the post-translational modification of FGF23 protein through a gene product of GALNT3 is the main regulatory mechanism of enhanced FGF23 production by high dietary Pi. Furthermore, high extracellular Pi directly activates FGFR1 and its downstream intracellular signaling pathway regulates the expression level of GALNT3.Conclusions We propose that FGFR1 works as a Pi-sensing receptor in the regulation of FGF23 production and serum Pi level. There is a negative feedback system, which is a basic mechanism of endocrine regulation, in the regulation of serum Pi involving FGFR1, and FGF23. These findings may lead to the development of new therapeutic methods to treat diseases caused by abnormal Pi level.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
