Analysis of Klotho 1 gene variants in not melanocytic skin cancer
2016
Aim of the study: The incidence of the vast majority of cancers, including melanoma and not melanocytic skin cancer (NMSC) increases with advancing age. However, the mechanism by which aging influences the risk of developing cancer is not fully understood. Whether this is attributable to declines in immunity or other changes, such as changes in the aging microenvironment, remains unclear. Amongst the many proteins implicated in aging is the protein Klotho. Loss of Klotho function results in the early appearance of several pathologies associated with human aging, downregulation of Klotho was found in several cancers, such as pancreatic cancer, HCC, and other tumors. Downregulation of Klotho …
Gender-specific soluble α-klotho levels as marker of GH deficiency in children: a case-control study.
2022
Abstract Purpose To evaluate circulating soluble α-klotho (sαKL) levels in GHD children before and after 12 months of GH treatment (GHT). Methods Auxological and basal metabolic parameters, oral glucose tolerance test for glucose and insulin levels, insulin sensitivity indices and klotho levels were evaluated before and after 12 months of follow-up in 58 GHD children and 56 healthy controls. Results At baseline, GHD children showed significantly lower growth velocity standard deviation score (SDS) (p < 0.001), bone/chronological age ratio (p < 0.001), GH peak and area under the curve (AUC) after arginine test (ARG) (both p < 0.001) and glucagon stimulation test (GST) (p < 0.001 …
Biomarkers for Antidepressant Efficacy of Electroconvulsive Therapy: An Exploratory Cerebrospinal Fluid Study
2018
<b><i>Background:</i></b> No candidate biomarkers based on cerebrospinal fluid (CSF) have been identified as prognostic factors in patients with major depression treated with electroconvulsive therapy (ECT), yet. <b><i>Method:</i></b> Following different underlying hypotheses, we analysed baseline CSF levels of markers of neurodegeneration (tau proteins, β-amyloids and neurogranin), elements of the innate immune system (interleukin [IL]-6, neopterin, soluble CD14, soluble CD163, migration inhibitory factor and monocyte chemotactic protein 1), endocannabinoids, sphingolipids and Klotho before ECT in patients with depression (<i>n</i>…
Improving Brain Creatine Uptake by Klotho Protein Stimulation: Can Diet Hit the Big Time?
2021
Creatine plays a pivotal role in cellular bioenergetics, acting as a temporal and spatial energy buffer in cells with high and fluctuating energy requirements (1). Jeopardizing delicate creatine homeostasis can be detrimental to many energy-demanding tissues, including the brain. For instance, cerebral creatine hypometabolism accompanies various neurological conditions, including a number of developmental disorders (2, 3), neurodegenerative and cerebrovascular diseases (4, 5), and brain cancer (6). A reduced creatine availability in the brain has been thus recognized as an apposite therapeutic target, and supplying exogenous creatine to compensate for a disease-driven shortfall emerged as a…
Klotho and vitamin D in multiple sclerosis: an Italian study
2019
Introduction Low vitamin D levels have been recognised as an important risk factor for autoimmune diseases, including multiple sclerosis (MS). MS is a multifactorial disease, the pathogenesis of which contributes both to genetic and environmental factors. Polymorphisms in genes codifying molecules involved in vitamin D homeostasis have been associated with hypovitaminosis D. However, the influence of polymorphisms of Klotho, which codify a protein with a pivotal role in vitamin D metabolism, have never been investigated. The aim of this study was to evaluate the association among genetic variants of Klotho, namely rs1207568 and rs9536314, serum 25(OH)D3 levels, and multiple sclerosis (both …
