Left ventricular hypertrophy (LVH) is a common complication in patients with CKD and an independent risk factor for death. Changes in the levels of uremic solutes or Klotho have been reported to be related to CKD, whereas the relationships between these factors and CKD-associated LVH remain unclear. Here, we investigated the interaction between Klotho and(More)
Renal fibrosis is the most common outcome of chronic kidney disease (CKD), while the pathogenesis of renal fibrosis is not fully understood. In this study, we first showed that the progress of renal fibrosis was positively related to serum levels of indoxyl sulfate, a typical protein-bound toxin, and that there was a close correlation between serum indoxyl(More)
Chronic renal failure (CRF) markedly accelerates the development of atherosclerosis, but the pathogenesis of uremic atherosclerosis remains to be elucidated. The klotho gene, predominantly expressed in the kidney, plays a key role in regulating aging and the development of age-related diseases in mammals. A loss of klotho results in multiple aging-like(More)
Estrogen induces endothelial progenitor cells (EPCs) migration and proliferation, which may serve as a potential target for coronary artery disease, but the mechanisms are unclear. We hypothesized that estrogen receptors (ERs) and phosphatidylinositol 3-kinase (PI3K) signaling pathway, which represent particularly important roles of action for estrogen, may(More)
The aim was to explore the effects of rapamycin on autophagy and injury of podocytes in streptozocin (STZ)-induced type 1 diabetic mice, and its role in delaying progression of diabetic nephropathy. In this study, male Balb/c mice were divided into three groups: control (n = 12), STZ-induced diabetic (n = 12), and rapamycin-treated diabetic (DM + Rapa) (n =(More)
The predominant transcription factors regulating key genes in diabetic kidney disease have not been established. The transcription factor upstream stimulatory factor 1 (USF1) is an important regulator of glucose-mediated transforming growth factor (TGF)-β1 expression in mesangial cells; however, its role in the development of diabetic kidney disease has not(More)
Increased basic fibroblast growth factor-2 (FGF2) and reduced Klotho have both been reported to be closely associated with renal fibrosis. However, the relationship between Klotho and FGF2 remains unclear. We demonstrate that FGF2 induced tubulo-epithelial plasticity in cultured HK-2 cells, accompanied by a reduction in Klotho expression, whereas(More)
The mechanisms of contrast medium (CM)-induced renal impairment at cellular level are not fully understood. The purpose of this study was to investigate the toxic effects of non-ionic low osmolar contrast medium (LOCM) on glomerular endothelial cells (GECs). Ioversol, the most representative LOCM used in clinic, was chosen to act on primary cultured rat(More)
Mesenchymal stem cells (MSC) attenuate albuminuria and preserve normal renal histology in diabetic mice. However, the effects of MSC on glomerular podocyte injury remain uncertain. The aim of this study was to evaluate the effects of MSC on podocyte injury in streptozotocin (STZ)-induced diabetic rats. Thirty days after diabetes induction by STZ injection(More)
Aristolochic acid nephropathy (AAN) is regarded as a kind of rapidly progressive renal fibrosis caused by the ingestion of herbal remedies containing aristolochic acid (AA). Recent studies showed that bone morphogenetic protein-7 (BMP-7) exerts beneficial effects on acute and chronic kidney injuries induced by different pathological conditions. We examined(More)
