Early and sustained changes in bone metabolism after severe burn injury.
Vienna, Austria. In J Clin Endocrinol Metab, Feb 2016
During the early phase pronounced increases were observed for CTX, P1NP, sclerostin, DKK-1, BALP, FGF23 and iPTH levels, whereas 25-OH vitamin D, albumin, serum and ionized calcium levels decreased.
CYP24 inhibition as a therapeutic target in FGF23-mediated renal phosphate wasting disorders.
In J Clin Invest, Feb 2016
Basal renal and extrarenal CYP24 is usually low but is highly induced by its substrate 1,25-dihydroxyvitamin D. Unbalanced high and/or long-lasting CYP24 expression has been proposed to underlie diseases like chronic kidney disease, cancers, and psoriasis that otherwise should favorably respond to supplemental vitamin D. Using genetically modified mice, we have shown that renal phosphate wasting hypophosphatemic states arising from high levels of fibroblast growth factor 23 (FGF23) are also associated with increased renal Cyp24 expression, suggesting that elevated CYP24 activity is pivotal to the pathophysiology of these disorders.
Pruning the ricket thicket.
In J Clin Invest, Feb 2016
UNASSIGNED: Overexpression of FGF23 results in hypophosphatemic rickets, which is characterized by renal phosphate wasting, inappropriately low circulating levels of the active form of vitamin D, and skeletal abnormalities.
Up-Regulation of FGF23 Release by Aldosterone.
Tübingen, Germany. In Biochem Biophys Res Commun, Feb 2016
UNASSIGNED: The fibroblast growth factor (FGF23) plasma level is high in cardiac and renal failure and is associated with poor clinical prognosis of these disorders.
Mineral and bone disorder after kidney transplantation.
Bangkok, Thailand. In World J Transplant, Jan 2016
During the first 3 mo, fibroblast growth factor-23 (FGF-23) and parathyroid hormone levels decrease rapidly in association with an increase in 1,25-dihydroxyvitamin D production.
The rachitic tooth.
Bethesda, United States. In Endocr Rev, 2014
Here we discuss conditions fitting under the umbrella of rickets, which traditionally referred to skeletal disease associated with vitamin D deficiency but has been more recently expanded to include newly identified factors involved in endocrine regulation of vitamin D, phosphate, and calcium, including phosphate-regulating endopeptidase homolog, X-linked, fibroblast growth factor 23, and dentin matrix protein 1. Systemic mineral metabolism intersects with local regulation of mineralization, and factors including tissue nonspecific alkaline phosphatase are necessary for proper mineralization, where rickets can result from loss of activity of tissue nonspecific alkaline phosphatase.
Phosphate and FGF-23.
Boston, United States. In Kidney Int, 2011
In human chronic kidney disease (CKD), plasma FGF-23 appears to be a sensitive biomarker of abnormal renal phosphate handling, as FGF-23 levels increase during early stages of kidney malfunction.
Phosphate and Klotho.
Dallas, United States. In Kidney Int, 2011
Klotho is a putative aging suppressor gene encoding a single-pass transmembrane co-receptor that makes the fibroblast growth factor (FGF) receptor specific for FGF-23.
