J Bone Miner Res. 2022 Feb;37(2):179-184.Abstract: https://pubmed-ncbi-nlm-nih-gov/34464000/In Brief: Fibroblast growth factor 23 (FGF23) and parathyroid hormone (PTH) both negatively regulate serum phosphate by increasing renal phosphate excretion. The clinical observation that both PTH and FGF23 are needed for adequate renal phosphate handling is confirmed in this experimental patient stu...
