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 ...
Background and Objectives: Different diets have important roles in human health and aging. In the current study, we aimed to characterize the Klotho, an anti-aging protein, gene expression and protein level in the serum and assess the protein levels of Transforming growth factor-β and Platelet-derived growth factor in old rats which treated with different diets (high-fat, high-protein, low calo...
The value of measuring IGF1 bioactivity in active acromegaly is unknown. Soluble Klotho (S-Klotho) level is elevated in active acromegaly and it has been suggested that S-Klotho can inhibit activation of the IGF1 receptor (IGF1R). A cross-sectional study was carried out in 15 patients with active acromegaly based on clinical presentation, unsuppressed GH during an oral glucose tolerance test, a...
Introdution: The aim of this study was to investigate the effect of vitamin D supplementation on Klotho levels of the brain tissue. Methods: In this laboratory experimental study, 25 female Lewis rats, after 2 weeks adaptation to lab environmental, were randomly divided into 5 groups: 1-control; 2- control+ EAE; 3-sham; 4vitamin D; 5-vitaminD + EAE. Results: The data were analyzed using one ...
Received: 16 Aug , 2015 Accepted: 22 Oct , 2015 Abstract Background & Aims: The aim of this study was to evaluate serum levels of antioxidant property Klotho by examining 8-hydroxy-2'- deoxyguanosine (8-OHdG), as a marker of oxidative damage in nucleic acids in patients with hemodialysis and kidney transplantation. Materials & Methods: Serum samples from 45 patients undergoing hem...
Background and Aims: Klotho protein is a substance effective in increasing life expectancy. Moreover, it prevents muscle atrophy, osteoporosis, and cardiovascular disease. Therefore, the present aimed to assess changes in the expression of klotho protein and insulin-like growth factor 1 (IGF-1) genes in the muscles of aged Wistar rats after eight weeks of resistance training. Materials and Met...
Background & Aims: Scleroderma is a chronic connective tissue disease with unknown etiology. Vitamin D, a necessary hormone that plays a particular function in the calcium and phosphate homeostasis, is involved in etiology of this disorder. Klotho, co-receptor of fibroblast growth factor 23 (FGF-23), can interfere in calcium and phosphate metabolism. The purpose of this study was to determ...
BACKGROUND Fibroblast growth factor 23 (FGF23), a bone-derived phosphaturic hormone, is elevated in chronic kidney disease (CKD). There are scarce data on the levels of its essential co-receptor klotho, and longitudinal changes in FGF23 levels are also unknown. METHODS We examined FGF23 and soluble klotho (s-klotho) levels over 1 year in 154 children with CKD Stages 1-5 (CKD1-5), were on dial...
The CKD-associated decline in soluble α-Klotho levels is considered detrimental. Some in vitro and in vivo animal studies have shown that anti-oxidant therapy can upregulate the expression of α-Klotho in the kidney. We examined the effect of anti-oxidant therapy on α-Klotho concentrations in a clinical cohort with mild tot moderate chronic kidney disease (CKD). We performed a post-hoc analysis ...
Emerging evidence suggests that alpha-processing single transmembrane proteins, amyloid precursor protein (APP) and anti-aging protein Klotho, are likely to be involved in the progression of Alzheimer's disease (AD). The natural phthalide Ligustilide (LIG) has been demonstrated to protect against aging- and amyloid-β (Aβ)-induced brain dysfunction in animal models. The present study is to inves...
