Abnormal upregulation of CYP24 contributes to vitamin D insufficiency and resistance to vitamin D therapy in chronic kidney disease (CKD), because human CYP24 is a key enzyme involved in the inactivation of 1a,25‐dihydroxyvitamin D3 (1a,25(OH)2D3; calcitriol) and 1,25(OH)2D3. There are multiple mechanisms regulating CYP24 in a variety of types of tissues and diseases. An increasing body of evidence...
AimTransforming growth factor‐β1 (TGF‐β1) plays a pivotal role in the progression of renal fibrosis. Reactive oxygen species mediate profibrotic action of TGF‐β1. Intermedin (IMD) has been shown to inhibit oxidative stress, but its role in renal fibrosis remains unclear. Here, we investigated the effects of IMD on renal fibrosis in a rat model of unilateral ureteral obstruction (UUO).

AimAn arteriovenous fistulae (AVF) is the preferred vascular access for maintenance haemodialysis patients. Its dysfunction is often due to venous stenosis, which is mainly caused by neointimal hyperplasia. Additionally, haemodynamic forces, especially wall shear stress (WSS), as a mechanical stimuli to venous wall have a significant role in neointimal hyperplasia. The purpose of this study was to...
