Fibroblast growth factor 23 (FGF23) is a bone-derived hormone that regulates and is regulated by blood levels of phosphate and active vitamin D. Post-translational glycosylation by the enzyme GALNT3 and subsequent processing by furin have been demonstrated to be a regulated process that plays a role in regulating FGF23 levels. In physiologic states, FGF23 signaling is mediated by an FGF receptor and the coreceptor, Klotho. Recent work identifying a role for iron/hypoxia pathways in FGF23 physiology and their implications are discussed. Beyond its importance in primary disorders of mineral metabolism, recent work implicates FGF23 in renal disease-associated morbidity, as well as possible roles in cardiovascular disease and skeletal fragility.
成纤维细胞生长因子 23(FGF23)是一种骨源激素,调节血液中磷酸盐和活性维生素 D 的水平,并受其调节。酶 GALNT3 的翻译后糖基化和随后的弗林蛋白酶处理已被证明是一种调节过程,在调节 FGF23 水平中发挥作用。在生理状态下,FGF23 信号通过 FGF 受体和辅助受体 Klotho 介导。最近的工作确定了铁/缺氧途径在 FGF23 生理学中的作用及其意义。除了在原发性矿物质代谢紊乱中的重要性外,最近的研究还表明 FGF23 与肾脏疾病相关的发病率有关,以及在心血管疾病和骨骼脆弱性中的可能作用。
