OBJECTIVES: The number of deaths from vascular diseases is incredibly high worldwide, and reliable markers for major events are still needed. The current cross-sectional study investigated the association of Klotho haplotypes and Klotho serum levels with classic risk factors and a clinical history of vascular events. METHODS: Clinical, anthropometric, biochemical and nutritional assessments w...
BACKGROUND To discover simple biomarkers to evaluate the aging or quality of human oocytes and clinical pregnancy rates is needed. However, the association among serum α-klotho concentrations during preimplantation, the aging or quality of human oocytes and clinical pregnancy rates has not been investigated. FINDINGS The serum α-klotho concentrations during preimplantation decreased due to ag...
BACKGROUND Scleroderma is a chronic connective tissue disease of unknown etiology. Vitamin D and parathyroid hormone (PTH) that play particular functions in calcium and phosphate homeostasis may be involved in the etiology of this disorder. Klotho, the co-receptor of the fibroblast growth factor 23 (FGF-23), can interfere with calcium and phosphate metabolism. The purpose of this study was to e...
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...
BACKGROUND Membrane αKlotho (hereinafter called Klotho) is highly expressed in the kidney and functions as a coreceptor of FGF receptors (FGFRs) to activate specific fibroblast growth factor 23 (FGF23) signal pathway. FGF23 is produced in bones and participates in the maintenance of mineral homeostasis. The extracellular domain of transmembrane Klotho can be cleaved by secretases and released i...
Klotho, named after a Greek goddess who spins the thread of life, was identified in 1997 as a gene mutated in a mouse strain that developed a premature ageing syndrome [1]. A defect in Klotho gene expression in mice results in shortened life span, growth retardation, hypogonadism, accelerated thymic involution, skin atrophy, muscle atrophy, vascular calcification, osteopaenia, pulmonary emphyse...
BACKGROUND The klotho gene was identified as an "aging-suppressor" gene that accelerates arterial calcification when disrupted. Serum and vascular klotho levels are reduced in patients with chronic kidney disease, and the reduced levels are associated with arterial calcification. Intake of eicosapentaenoic acid (EPA), an n-3 fatty acid, reduces the risk of fatal coronary artery disease. However...
AIMS/INTRODUCTION Recent studies have shown that periodontitis can contribute to adipose tissue inflammation and subsequent systemic insulin resistance in the obese rat model. However, the related inflammatory mechanism is not yet clear. The present study aims to investigate the effects of periodontitis on the function of pancreatic β-cells with pro-inflammatory cytokines-related immune mechani...

Alveolar epithelial cell (AEC) apoptosis and inadequate repair resulting from "exaggerated" lung aging and mitochondrial dysfunction are critical determinants promoting lung fibrosis. α-Klotho, which is an antiaging molecule that is expressed predominantly in the kidney and secreted in the blood, can protect lung epithelial cells against hyperoxia-induced apoptosis. We reasoned that Klotho prot...
