Phosphaturic action of fibroblast growth factor 23 in Npt2 null mice.
In the present study, we evaluated the roles of type II and type III sodium-dependent P(i) cotransporters in fibroblast growth factor 23 (FGF23) activity by administering a vector encoding FGF23 with the R179Q mutation (FGF23M) to wild-type (WT) mice, Npt2a knockout (KO) mice, Npt2c KO mice, and Npt2a(-/-)Npt2c(-/-) mice (DKO mice). In Npt2a KO mice, FGF23M induced severe hypophosphatemia and m...
متن کاملFibroblast growth factor 23 is a counter-regulatory phosphaturic hormone for vitamin D.
The regulation of the phosphaturic factor fibroblast growth factor 23 (FGF23) is not well understood. It was found that administration of 1,25-dihydroxyvitamin D(3) (1,25[OH](2)D(3)) to mice rapidly increased serum FGF23 concentrations from a basal level of 90.6 +/- 8.1 to 213.8 +/- 14.6 pg/ml at 8 h (mean +/- SEM; P < 0.01) and resulted in a four-fold increase in FGF23 transcripts in bone, the...
متن کاملFibroblast Growth Factor 21 Mediates Specific Glucagon Actions
Glucagon, an essential regulator of glucose homeostasis, also modulates lipid metabolism and promotes weight loss, as reflected by the wasting observed in glucagonoma patients. Recently, coagonist peptides that include glucagon agonism have emerged as promising therapeutic candidates for the treatment of obesity and diabetes. We developed a novel stable and soluble glucagon receptor (GcgR) agon...
متن کاملAnalysis of the biochemical mechanisms for the endocrine actions of fibroblast growth factor-23.
Fibroblast growth factor (FGF)-23 has emerged as an endocrine regulator of phosphate and of vitamin D metabolism. It is produced in bone and, unlike other FGFs, circulates in the bloodstream to ultimately regulate phosphate handling and vitamin D production in the kidney. Presently, it is unknown which of the seven principal FGF receptors (FGFRs) transmits FGF23 biological activity. Furthermore...
متن کاملHow fibroblast growth factor 23 works.
There is a discontinuum of hereditary and acquired disorders of phosphate homeostasis that are caused by either high or low circulating levels of the novel phosphaturic hormone fibroblastic growth factor 23 (FGF23). Disorders that are caused by high circulating levels of FGF23 are characterized by hypophosphatemia, decreased production of 1,25-dihydroxyvitamin D, and rickets/osteomalacia. On th...
