Fibroblast growth factor 23 (FGF23) is a hormone that is mainly secreted by osteocytes and osteoblasts in bone. The critical role of FGF23 in mineral ion homeostasis was first identified in human genetic and acquired rachitic diseases and has been further characterised in animal models. Recent studies have revealed that the levels of FGF23 increase significantly at the very early stages of chronic kidney disease (CKD) and may play a critical role in mineral ion disorders and bone metabolism in these patients. Our recent publications have also shown that FGF23 and its cofactor, Klotho, may play an independent role in directly regulating bone mineralisation instead of producing a systematic effect. In this review, we will discuss the new role of FGF23 in bone mineralisation and the pathophysiology of CKD-related bone disorders.
成纤维细胞生长因子23(FGF23)是一种主要由骨中的骨细胞和成骨细胞分泌的激素。FGF23在矿物质离子稳态中的关键作用最初是在人类遗传性和获得性佝偻病疾病中发现的,并在动物模型中得到了进一步的表征。最近的研究表明,在慢性肾脏病(CKD)的极早期阶段,FGF23水平会显著升高,并且可能在这些患者的矿物质离子紊乱和骨代谢中起关键作用。我们最近的出版物还表明,FGF23及其辅助因子α-klotho可能在直接调节骨矿化方面发挥独立作用,而不是产生系统性影响。在这篇综述中,我们将讨论FGF23在骨矿化中的新作用以及CKD相关骨疾病的病理生理学。
