Fibroblast growth factor 23 (FGF23), a known regulator of phosphate homeostasis, is produced by cells residing in bone, namely, osteocytes, to target a distant organ, the kidney. Elevated FGF23 levels have recently been found systemically and in osteocytes in patients and animal models of chronic kidney disease. Associations between serum FGF23 level and vascular dysfunction, vascular calcification, and increased risk of cardiovascular disease have also been observed. In this review we discuss FGF23 expression in osteocytes and the potential means to regulate expression and function of this protein at the osteocyte level.
成纤维细胞生长因子 23(FGF23)是一种已知的磷酸盐稳态调节剂,由存在于骨中的细胞(即骨细胞)产生,以靶向远处的器官,即肾脏。最近在慢性肾脏病患者和动物模型中发现了全身性和骨细胞中升高的 FGF23 水平。还观察到血清 FGF23 水平与血管功能障碍、血管钙化和心血管疾病风险增加之间存在关联。在这篇综述中,我们讨论了骨细胞中的 FGF23 表达以及在骨细胞水平上调节这种蛋白质表达和功能的潜在方法。
