Tumor-induced osteomalacia (TIO) is caused by the hormone fibroblast growth factor 23 (FGF-23). It is mainly produced in the tissue of mesenchymal tumors. Patients with TIO frequently suffer from a chronic decompensated pain syndrome and/or muscle weakness with postural deformity. Despite the severity of the disease, the diagnosis is frequently established late. In some cases, it takes several years to establish the condition. This case report concerning a 68-year old woman demonstrates the selective blood sampling for FGF-23 as path-breaking diagnostics to confirm the diagnosis of a neuroendocrine tumor...

BACKGROUND: Fibroblast growth factor 21 (FGF-21) is mainly secreted by liver and has been reported to be involved in the pathogenesis of type 2 diabetes. Some prospective studies have shown a positive association between FGF-21 and diabetes risk. However, no study has examined whether the association differed by sex, which has been reported between FGF-21 and atherosclerosis. Therefore, we prospectively evaluated the sex-specific association between FGF-21 and diabetes in a Chinese population...

Calcium and inorganic phosphate are of critical importance for many body functions, thus the regulations of their plasma concentrations are tightly controlled by the concerted actions of reabsorption/excretion in the kidney, absorption in the intestines, and exchange from bone, the major reservoir for calcium and phosphate in the body. Parathyroid hormone (PTH) and 1,25-dihydroxyvitamin D (1,25(OH)2D) control calcium homeostasis, whereas PTH, 1,25(OH)2D, and bone-derived fibroblast growth factor 23 (FGF 23) control phosphate homeostasis...

The inner cell mass of the mouse blastocyst gives rise to the pluripotent epiblast (EPI), which forms the embryo proper, and the primitive endoderm (PrE), which forms extra-embryonic yolk sac tissues. All inner cells co-express lineage markers such as Nanog and Gata6 at embryonic day (E) 3.25, and the EPI and PrE precursor cells eventually segregate to exclusively express Nanog and Gata6, respectively. Fibroblast growth factor (FGF)/extracellular signal-regulated kinase (ERK) signalling is involved in segregation of the EPI and PrE lineages; however, the mechanism involved in Fgf4-regulation is poorly understood...

Deranged vitamin D metabolism represents an active trigger of secondary hyperparathyroidism (SHPT) in CKD. Correction of 25(OH)D deficiency by nutritional Vitamin D administration is suggested by KDIGO guidelines, to prevent and treat SHPT in CKD stage G3-G5 and G1T-G5T patients, although with a still inconsistent background. Nutritional vitamin D is available as cholecalciferol, ergocalciferol, or calcifediol. Superiority of calcifediol in increasing 25(OH)D levels has been suggested due to its better bioavailability...

Heparin-binding protein 17 (HBp17)/fibroblast growth factor-binding protein-1 (FGFBP-1) was first purified from medium conditioned by A431 cells for its capacity to bind to fibroblast growth factors 1 and 2 (FGF-1 and -2). Among FGF family members, FGF-2 is a potent mitogen for various cell types, including vascular endothelial cells, fibroblasts, and cancer cells such as oral squamous cell carcinoma (OSCC) cells. Besides being well known in bone metabolism, the active form of vitamin D3, i.e., 1α,25(OH)2D3 (1,25D3), was reported to have protective effects for heart disease and cancer...

Transforming growth factor-β (TGF-β) is a cytokine produced by many cell types and implicated in cell growth, differentiation, apoptosis, and inflammation. It stimulates store-operated calcium entry (SOCE) through the calcium release-activated calcium (CRAC) channel Orai1/Stim1 in endometrial Ishikawa cells. Bone cells generate fibroblast growth factor (FGF) 23, which inhibits renal phosphate reabsorption and 1,25(OH)2D3 formation in concert with its co-receptor Klotho. Moreover, Klotho and FGF23 counteract aging and age-related clinical conditions...

Sclerostin inhibits Wnt/β-catenin signaling pathway, thereby decreasing bone formation. Osteoblast stimulating actions of parathyroid hormone (PTH) are mediated by suppression of sclerostin. Thus, sclerostin may reflect both bone metabolism and parathyroid function. The study was aimed to analyze the patterns of the changes of mineral and bone biomarkers for 9 months following kidney transplantation (KTx). Thirty-five patients after KTx were included into a 9-month observational study. Serum creatinine, calcium, phosphorus, 25-OH vitamin D, PTH, fibroblast growth factor 23 (FGF-23), sclerostin, and bone-specific alkaline phosphatase (BAP) were measured before KTx, and 1, 2 weeks, and 1, 2, 3, 4, 5, 6, and 9 months thereafter...

INTRODUCTION: Patients on haemodialysis (HD) have a high prevalence of 25-OH-vitamin D (25-OH-D)deficiency. Secondary hyperparathyroidismis a common condition in these patients, which is very important to control. 25-OH-D is involved in regulating calcium homeostasis. As such, appropriate levels of this vitamin could help to control bone mineral metabolism. OBJECTIVE: To evaluate the effect 25-OH-D repletion in HD patients with 25-OH-D deficiency (<20ng/ml) on the control of secondary hyperparathyroidism and microinflammation status...

Background: Membrane-bound α-klotho functions as a co-receptor with fibroblast growth factor receptor at the renal tubule conferring specificity to fibroblast growth factor-23 (FGF-23), allowing it to inhibit tubular phosphate reabsorption at physiological concentrations. α-klotho also exists as a soluble protein. However, the complex interrelationships between soluble α-klotho (sKl), FGF-23 and phosphate reabsorption are poorly understood, with little known about the links between sKl, FGF-23 and phosphate reabsorption in chronic kidney disease (CKD)...

AGC(®) (Automatic Gas Control) is the FLOW-i's automated low flow tool (Maquet, Solna, Sweden) that target controls the inspired O2 (FIO2) and end-expired desflurane concentration (FAdes) while (by design) exponentially decreasing fresh gas flow (FGF) during wash-in to a maintenance default FGF of 300 mL min(-1). It also offers a choice of wash-in speeds for the inhaled agents. We examined AGC performance and hypothesized that the use of lower wash-in speeds and N2O both reduce desflurane usage (Vdes). After obtaining IRB approval and patient consent, 78 ASA I-II patients undergoing abdominal surgery were randomly assigned to 1 of 6 groups (n = 13 each), depending on carrier gas (O2/air or O2/N2O) and wash-in speed (AGC speed 2, 4, or 6) of desflurane, resulting in groups air/2, air/4, air/6, N2O/2, N2O/4, and N2O/6...
