BACKGROUND HIV-associated nephropathy is accompanied by significant tubular alterations in the form of tubular cell proliferation, apoptosis, and microcystic dilatation. In the present study we evaluated the role of CD4 receptors in HIV-1-induced tubular cell injury. METHODS To confirm the presence of CD4 receptors in tubular cells, immunocytochemical, Western and Northern blot studies were c...

acute renal damage mainly develops following toxic or ischemic insults and is defined as acute. these damages have largely been attributed to oxidative stress. recently much attention has been directed toward decreased renal tubular cell regeneration during tubular cell injury. antioxidants have recently been the focus of researchers and scientists for prevention and treatment of various oxidat...

background: in most mammals, the testis is always maintained at a lower temperature than that in the abdomen, and exposure of the testis to body temperature causes degeneration of germ cells. objective: in this research, the long effect of heat exposure on sperm parameters and microstructure of mouse testis were investigated. cryptorchid mouse were induced by exposure to abdominal heat. materia...

BACKGROUND Tubular repair upon injury involves regeneration from either surviving tubular epithelial cells or from their surviving local progenitor cells; hence, compound screening with cell lines may be inadequate. Here, we demonstrate that the renal cell isolation procedure and subsequent outgrowth of tubular cells can mimic the renal injury phase and tubular cell regeneration from whichever ...

Our previous studies have suggested a critical role of reticulon (RTN)1A in mediating endoplasmic reticulum (ER) stress in kidney cells of animal models and humans with kidney diseases. A large body of evidence suggests that proteinuria itself can cause tubular cell injury leading to the progression of kidney disease. In the present study, we determined whether RTN1A mediates proteinuria-induce...

During acute kidney injury (AKI), tubular cell dedifferentiation initiates cell regeneration; hepatocyte growth factor (HGF) is involved in modulating cell dedifferentiation. Mesenchymal stem cell (MSC)-derived microvesicles (MVs) deliver RNA into injured tubular cells and alter their gene expression, thus regenerating these cells. We boldly speculated that MVs might induce HGF synthesis via RN...

Objective(s): Cisplatin is an effective antineoplastic agent; its clinical utility, however, is limited by a few salient toxic side effects like nephrotoxicity. This study aimed to determine the potential protective effects of tangeretin, a citrus-derived flavonoid, against renal tubular cell injury in cisplatin-induced renal toxicity of rats.Materials and Methods: Tangeretin was injected intra...

Solid oxide fuel cells that are designed in different geometrical structures (planar, tubular, flat-tubular, etc.) dirt-free, quiet, and efficient run using fuels including contagions fuels. In this work, the performance of a 3D model direct ammonia feed anode supported flat-tubular solid cell having six supply channels was developed, investigated, elucidated numerically comparison with hydroge...
