Heme oxygenase-1 (HO-1), a cytoprotective gene, is commonly induced in renal tubules in the diseased kidney. Because proteinuria is a hallmark for kidney disease, we examined the relationship between proteinuria and tubular induction of HO-1, specifically questioning whether increased trafficking of protein across the renal tubular epithelium, as a consequence of proteinuria, induces tubular ex...

Dabigatran is a direct thrombin inhibitor used as an alternative to warfarin for long-term anticoagulation. We describe a patient who developed acute kidney injury (AKI) in the setting of warfarin conversion to dabigatran, and a renal biopsy demonstrating acute tubular injury. Although the patient had undiagnosed IgA nephropathy that may have predisposed him to bleeding, AKI was due to heme-ass...

BACKGROUND The effect of segment-specific proximal tubular injury on spatio-temporal osteopontin (OPN) distribution was determined in two different nephrotoxic rat models to evaluate its conceivability with a possible role for OPN in acute renal failure (ARF). OPN gene expression was further determined in proximal and distal tubular cells to investigate the origin of increased renal OPN. METH...

Previously we reported that the consecutive injection of lipopolysaccharide (LPS) into LPS-sensitized mice for the generalized Shwartzman reaction (GSR) appeared to induce the injury of renal tubular epithelial cells via apoptosis. The aim of this study was to characterize the mechanism of renal tubular epithelial cell injury in GSR. The expression of Fas and Fas ligand was immunohistochemicall...

BACKGROUND Acid-sensing ion channels (ASICs) are ligand-gated cation channels activated by extracellular protons. However, the role of ASICs in kidney diseases remains uncertain. This study investigated ASICs expression in kidney tissues and their role in the development of Henoch-Schönlein purpura nephritis (HSPN). MATERIAL AND METHODS The expression of ASIC subunits was examined by immunochem...

Objective(s): Cisplatin (Cis) is an anticancer compound, which is used for the treatment of various cancers. Sumatriptan (Suma) is a selective agonist of 5-hydroxytryptamine 1B/1D (5HT1B/1D) receptor, which is prescribed for the management of migraine. It is well-established that Suma has anti-inflammatory and antioxidant properties. We have explored the protective effe...

NF-κB is a key regulator of innate and adaptive immunity and is implicated in the pathogenesis of acute kidney injury (AKI). The cell type-specific functions of NF-κB in the kidney are unknown; however, the pathway serves distinct functions in immune and tissue-parenchymal cells. We analyzed tubular epithelial-specific NF-κB signaling in a mouse model of ischemia-reperfusion injury (IRI)-induce...

INTRODUCTION A pro-apoptotic effect of circulating mediators on renal tubular epithelial cells has been involved in the pathogenesis of sepsis-associated acute kidney injury (AKI). Adsorption techniques have been showed to efficiently remove inflammatory cytokines from plasma. The aim of this study was to evaluate the efficiency of the hydrophobic resin Amberchrom CG161 M to adsorb from septic ...
