The pathogenesis of cisplatin-induced acute kidney injury (AKI) is characterized by tubular cell apoptosis and inflammation. However, the molecular mechanisms are not fully understood. We found that CXCL16 was induced in renal tubular epithelial cells in response to cisplatin-induced AKI. Therefore, we investigated whether CXCL16 played a role in cisplatin-induced tubular cell apoptosis and inf...
Administration of estrogen (E) to immature chicks triggers the cytodifferentiation of tubular gland cells in the magnum portion of the oviduct epithelium ; these cells synthesize the major egg-white protein, ovalbumin. Electron microscopy and immunoprecipitation of ovalbumin from oviduct explants labeled with radioactive amino acids in tissue culture were used to follow and measure the degree o...
background & objectives: tubular adenomas are rare benign epithelial tumours of breast affecting predominantly females of child bearing age group. till now, very small number of cases have been reported in the literature. present study was carried out to evaluate the clinico-pathological features of tubular adenoma cases diagnosed during three years study period along with discussion of pos...
Aldosterone (Aldo) is an independent risk factor for chronic kidney disease (CKD), and although Aldo directly induces renal tubular cell injury, the underlying mechanisms remain unclear. NLRP3 inflammasome and mitochondrial reactive oxygen species (ROS) have recently been implicated in various kinds of CKD. The present study hypothesized that mitochondrial ROS and NLRP3 inflammasome mediated Al...
Retention of crystals in the kidney is an essential early step in renal stone formation. Studies with renal tubular cells in culture indicate that hyaluronan (HA) and osteopontin (OPN) and their mutual cell surface receptor CD44 play an important role in calcium oxalate (CaOx) crystal binding during wound healing. This concept was investigated in vivo by treating rats for 1, 4, and 8 d with eth...
BACKGROUND Hypoxia-induced renal tubular cell epithelial-mesenchymal transition (EMT) is an important event leading to renal fibrosis. MicroRNAs (miRNAs) are small non-coding RNA molecules that bind to their mRNA targets, thereby leading to translational repression. The role of miRNA in hypoxia-induced EMT is largely unknown. METHODOLOGY/PRINCIPAL FINDINGS miRNA profiling was performed for th...
Polycystic kidneys are caused by an amazingly broad array of genetic mutations and manipulations. The ciliary hypothesis has evolved as the unifying concept of cystogenesis: cilia, bend by fluid flow, initiate a calcium influx that prevents cyst formation. The integrity of ciliary functions has been linked to the polycystic kidney disease gene products localizing to the cilium or the basal body...
The pathogenesis of chronic cyclosporine A (CsA) nephrotoxicity has not been elucidated, but apoptosis is thought to play an important role in CsA induced tubular atrophy. Recently Fas-Fas ligand system mediated apoptosis has been frequently reported in many epithelial cells as well as in T lymphocytes. We investigated the ability of CsA to induce apoptosis in cultured human proximal tubular ep...
Brefeldin A (BFA) induces the formation of an extensively fused network of membranes derived from the trans-Golgi network (TGN) and early endosomes (EE). We describe in detail here the unaffected passage of endocytosed material through the fused TGN/EE compartments to lysosomes in BFA-treated cells. We also confirmed that BFA caused the formation of tubular lysosomes, although the kinetics and ...
Collagen-based hydrogels are widely used for three-dimensional (3D) culture of mammalian cells because their high cell-activating characteristis. However, techniques preparing cell-embedding collagen with micrometer-size precision in perfusable, microfluidic devices have not been fully developed. In this study, we propose a facile strategy enabling microfabrication devices. We phosphate particl...
