Ethanolic extract of flowers of Pongamia pinnata was studied for its protective effect against cisplatin and gentamicin induced renal injury in rats. When the extract (300 & 600 mg kg(-1)) was administered orally for 10 days following cisplatin (5 mg kg(-1) i.p.) on day 5, toxicity of cisplatin, as measured by loss of body weight, elevated blood urea and serum creatinine declined significantly....

Objective(s) Portulaca oleracea L. is a herbaceous weed from portulacaceae family. It can be found in many parts of the world. Modern pharmacological studies have demonstrated that P. oleracea have antioxidant effects. The protective effect of aqueous and ethanolic extract of P. oleracea against cisplatin-induced renal toxicity was studied in rats. Materials and Methods Single intraperitonea...

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...

BACKGROUND Prophylactic mineralocorticoid receptor (MR) antagonism with spironolactone (Sp) in rats completely prevents renal damage induced by ischemia. Because acute renal ischemia cannot typically be predicted, this study was designed to investigate whether Sp could prevent renal injury after an ischemic/reperfusion insult. METHODS Six groups of male Wistar rats were studied: rats that rec...

Ischemia/reperfusion (I/R) injury is a common cause of injury to target organs such as brain, heart, and kidneys. Renal injury from I/R, which may occur in renal transplantation, surgery, trauma, or sepsis, is known to be an important cause of acute kidney injury. The detailed molecular mechanism of renal I/R injury is still not fully clear. Here, we investigate the role of AMP-activated protei...

background and aims: methotrexate (mtx), a folic acid antagonist, is widely used as a treatment for malignancies as well as in the treatment of various inflammatory and autoimmune disorders. nephrotoxicity is an important side-effect of this drug. prevention and treatment of mtx-induced renal dysfunction are essential to prevent potentially life-threatening mtx-associated toxicities, present st...

Acute renal failure (ARF) induces tubular hyperresponsiveness to TLR4 ligands, culminating in exaggerated renal cytokine/chemokine production. However, the fate of TLR4 protein during acute tubular injury remains unknown. The study sought new insights into this issue. Male CD-1 mice were subjected to 1) unilateral ischemia-reperfusion (I/R), 2) cisplatin (CP) nephrotoxicity, or 3) glycerol-indu...

He S, Liu N, Bayliss G, Zhuang S. EGFR activity is required for renal tubular cell dedifferentiation and proliferation in a murine model of folic acid-induced acute kidney injury.
