Aging is the primary risk factor for cognitive decline, an emerging health threat to aging societies worldwide. Whether anti-aging factors such as klotho can counteract cognitive decline is unknown. We show that a lifespan-extending variant of the human KLOTHO gene, KL-VS, is associated with enhanced cognition in heterozygous carriers. Because this allele increased klotho levels in serum, we an...
INTRODUCTION Vascular calcification is a common, serious and elusive complication of end-stage renal disease (ESRD). As a pro-calcifying risk factor, non-thyroidal illness may promote vascular calcification through a systemic lowering of vascular calcification inhibitors such as matrix-gla protein (MGP) and Klotho. METHODS AND MATERIAL In 97 ESRD patients eligible for living donor kidney tran...
Klotho plays an important role in the pathogenesis of cardiovascular disease in chronic kidney disease (CKD). Klotho is highly expressed in the kidney and parathyroid glands, but its presence in the vasculature is debated. Renal Klotho is decreased in CKD, but the effect of uremia on Klotho in other tissues is not defined. The effect of vitamin D receptor activator therapy in CKD on the express...
Chronic kidney disease (CKD) is a state of Klotho deficiency. The Klotho expression may be suppressed due to DNA hypermethylation in cancer cells so we have investigated the effects and possible mechanisms by which Klotho expression is regulated in human aortic smooth muscle cells (HASMCs). The vascular Klotho hypermethylation in radial arteries of patients with end-stage renal disease was desc...
Transmembrane α-Klotho (TM-Klotho), mainly expressed in renal distal tubules, is a co-factor for FGF23 receptor. Circulating soluble α-Klotho (s-Klotho) results from shedding of the ecto-domain of TM-Klotho and has specific effects on urinary Phosphate (P) and Calcium (Ca) transport. The possibility exists that a decrease in TM-Klotho, described in experimental chronic kidney disease (CKD), may...
The secretive Klotho protein is an anti-aging regulatory hormone that plays a physiological role in many target organs. The present study aims to investigate the correlation between Klotho gene and mild cognitive impairment (MCI) in Uygur and Han populations in Xinjiang. From July 2008 to April 2014, stratified random multistage cluster sampling was used in combination with the methods of on-si...
INTRODUCTION Low levels of vitamin D are linked to numerous adverse clinical conditions in hemodialysis (HD) patients, including disturbances of mineral and bone metabolism and increased mortality. Klotho, a molecule involved in such processes as phosphate homeostasis and aging, exists in 2 forms: a transmembrane protein acting as a coreceptor for fibroblast growth factor 23 (FGF-23) and solubl...
There are no pathophysiolgical therapeutic approaches to acute kidney injury (AKI) and the mortality remains high. In addition chronic kidney disease (CKD) predisposes to AKI and AKI contributes to progression of CKD. Recently a transcriptomics approach unveiled a relationship between AKI, inflammation and the regulation of ageing. A transcriptomics analysis of experimental AKI revealed increas...
Human CD4(+) T lymphocytes undergo aging-related changes leading to decreased immunity to infections and neoplasms, and to increased frequency of autoimmune diseases including rheumatoid arthritis (RA). Certain changes, observed in the CD4(+) cells of RA patients, resemble those observed during physiological aging, but occur at earlier age. Underlying cellular mechanism(s) of these similarities...
Mitochondrial enzyme activities and ultrastructure of mitochondria prepared from klotho mutant mice were compared with those in wild-type mice. We also measured the levels of expression of ND1, 51kDa, and 75kDa mRNA associated with the genes encoding NADH dehydrogenase and complex I and that of alpha cardiac myosin heavy chain mRNA in both groups. Mitochondrial NADH oxidoreductase activity was ...
