A novel circulation phosphaturic hormone is postulated to regulate systemic phosphate homeostasis. Two new studies reveal that the phosphaturic factor FGF-23 is increased in hypophosphatemic subjects with McCune-Albright syndrome and that secreted frizzled-related protein-4 (sFRP-4), a factor produced by tumors derived from subjects with tumor-induced osteomalacia, also has phosphaturic activity. It remains to be established whether FGF-23 and sFRP-4 represent two distinct phosphatonins or are somehow integrated in a novel phosphate-regulating bone-kidney axis.
一种新型的循环磷尿激素被推测可调节全身磷酸盐稳态。两项新研究表明,在患有McCune-Albright综合征的低磷血症患者中,磷尿因子FGF-23水平升高,并且来自肿瘤诱导骨软化症患者的肿瘤产生的因子——分泌型卷曲相关蛋白4(sFRP-4)也具有磷尿活性。FGF-23和sFRP-4是代表两种不同的磷调节素,还是以某种方式整合在一种新型的磷酸盐调节骨-肾轴中,仍有待确定。
