The aim of the present study was to evaluate the concentrations of fetuin-A, osteoprotegerin (OPG) and α-Klotho protein in patients with alcoholic cirrhosis at different stages of the disease, and to demonstrate that fetuin-A, osteoprotegin and α-Klotho may be used as markers of the severity of cirrhosis. A total of 54 patients with alcoholic liver cirrhosis treated in various hospitals in the ...
BACKGROUND Soluble α-klotho may influence energy homeostasis. It also plays a role in calcium-phosphate and vitamin D3 metabolism regulation. Two so far published studies have demonstrated that serum α-klotho levels in patients with AN are decreased, but their relationships with BMI and metabolic disturbances in these patients remain unclear. OBJECTIVES The aim of the study was to assess the ...
Klotho mutant (kl/kl) mice exhibit growth retardation after weaning, and previous electron microscopic examination of GH-producing cells in pituitary glands revealed a reduction in GH granules. However, it has not been known whether growth retardation in klotho mutant mice is related to the loss of GH function. We therefore examined whether treatment with GH could rescue the retardation of grow...
Cellular senescence can be prematurely induced by oxidative stress involved in aging. In this work, we were searching for novel intermediaries in oxidative stress-induced senescence, focusing our interest on integrin-linked kinase (ILK), a scaffold protein at cell-extracellular matrix (ECM) adhesion sites, and on the Klotho gene. Cultured renal cells were treated with glucose oxidase (GOx) for ...
Klotho acts as a co-receptor for and dictates tissue specificity of circulating FGF23. FGF23 inhibits PTH secretion, and reduced Klotho abundance is considered a pathogenic factor in renal secondary hyperparathyroidism. To dissect the role of parathyroid gland resident Klotho in health and disease, we generated mice with a parathyroid-specific Klotho deletion (PTH-KL(-/-)). PTH-KL(-/-) mice had...
PURPOSE To determine whether the age-regulating protein klotho was expressed in the retina and determine whether the absence of klotho affected retinal function. METHODS Immunohistochemistry and qPCR of klotho knockout and wild-type mice were used to detect klotho expression in retina. Immunohistochemistry was used to probe for differences in expression of proteins important in synaptic funct...
Implication for health policy/practice/research/medical education: Klotho is a newly discovered protein with pleotropic effects and have affected different fields of renal medicine from translational research to clinical nephrology. Here we want to summarize some new scopes in the field of renal fibrosis and Klotho with this hope that in future it could be implemented as a new therapeutic strat...
BACKGROUND Diabetes is associated with a high incidence of macrovascular disease (MVD), including peripheral and coronary artery disease. Circulating soluble-Klotho (sKlotho) is produced in the kidney and is a putative anti-aging and vasculoprotective hormone. Reduced Klotho levels may therefore increase cardiovascular risk in diabetes. We investigated if sKlotho levels are decreased in type 2 ...
Transgenic mice overexpressing fibroblast growth factor (FGF23) (R176Q) (F(Tg)) exhibit biochemical {hypophosphatemia, phosphaturia, abnormal 1,25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)] metabolism} and skeletal (rickets and osteomalacia) abnormalities attributable to FGF23 action. In vitro studies now implicate the aging-related factor Klotho in the signaling mechanism of FGF23. In this study,...
The discovery that two recently identified molecules, klotho and fibroblast growth factor 23 (FGF23), played an important role in calcium, phosphate, and vitamin D metabolism has transformed our traditional physiological view in which bone and mineral homeostasis was mainly regulated by parathyroid hormone, vitamin D, and calcitonin, according to mineral body needs. FGF23 is a 251-amino acid se...
