Deranged calcium-phosphate metabolism contributes to the burden of morbidity and mortality in dialysis patients. This study aimed to assess the association of the phosphaturic hormone fibroblast growth factor 23 (FGF23) and soluble Klotho with all-cause mortality. We measured soluble Klotho and FGF23 levels at enrolment and two weeks later in 239 prevalent hemodialysis patients. The primary hyp...

OBJECTIVE To identify whether α-Klotho is a kind of acute phase protein and alternation in the level of protein and mRNA under restraint stress. METHOD 48 mice were divided into three groups of 16: 1h, 10h and 20 h treat time group. Each group included restraint stress and control subgroup with same number animals (n = 8). ELISA was utilized in the assay of serum α-Klotho and corticosterone, ...

BACKGROUND Valvular and vascular calcification are important early aging phenotypes and represent risk factors for cardiovascular morbidity and mortality. Klotho is a gene primarily expressed in the kidney that has an important role in calcium-phosphate homeostasis. The functional KL-VS variant of Klotho has been associated with aging and cardiovascular disease in human studies, but its role in...

Klotho is a recently discovered antiaging gene. The objective of this study was to test the hypothesis that klotho gene delivery attenuates the progression of spontaneous hypertension and renal damage in spontaneous hypertensive rats (SHRs). An adeno-associated virus (AAV) carrying mouse klotho full-length cDNA (AAV.mKL) was constructed for in vivo expression of klotho. Four groups of male SHRs...

A defect in Klotho gene expression in the mouse results in a syndrome that resembles rapid human aging. In this study, we investigated the detailed distribution and the time of the first appearance of Klotho in developing and adult mouse kidney. Kidneys from 16-(F16), 18-(F18) and 20-day-old (F20) fetuses, 1- (P1), 4- (P4), 7- (P7), 14- (P14), and 21-day-old (P21) pups and adults were processed...

Kolorektal kanser dünyada en sık görülen gastrointestinal türüdür. Klotho, bedende fosfat ve kalsiyum homeostazının düzenlenmesinde önemli rol oynayan, hormon görevi de gören yaşlanma karşıtı glikozile edilmiş transmembran bir proteindir. Klotho sadece "yaşlanma baskılayıcı" olarak işlev görmez, aynı zamanda hücrenin hayatta kalmasını çoğalmasını da düzenler metastazında oynayan potansiyel tümö...

Reduced baroreflex sensitivity (BRS) is widely observed in diabetic human and animals. Rosiglitazone is one of the clinically used thiazolidinediones (TZD) known as PPAR γ agonist. Additionally, the klotho protein produced from choroid plexus in the central nervous system is regulated by PPAR γ . In an attempt to develop the new therapeutic strategy, we treated streptozotocin-induced diabetic r...

Different studies support the notion that chronic aerobic exercises training can influence the circulating levels of soluble-Klotho (s-Klotho) and insulin-like growth factor 1 (IGF-I). The effects of s-Klotho include improving the quality of life, alleviating the negative impact of age on the body's work capacity, and possibly increasing longevity. This review provides an overview of the latest...

BACKGROUND/AIMS Shiga toxin 2 may trigger classical hemolytic uremic syndrome (HUS) eventually leading to renal failure. Klotho, a transmembrane protein, protease and hormone mainly expressed in kidney is involved in the regulation of renal phosphate excretion and also retains renal protective effects. Renal failure is associated with renal depletion of klotho. The present study explored the in...

Ageing is a multifactorial process often characterized by a progressive decline in physiological function(s). Ageing can and is often associated with an increased incidence of cardiovascular and renal disease. Klotho is a novel antiageing gene that encodes a protein with multiple pleiotropic functions including an emerging role in cardiorenal disease. Mice deficient for this gene display a phen...
