BACKGROUND Detection of acute kidney injury (AKI) is still a challenge if conventional markers of kidney function are within reference range. We studied the sensitivity and specificity of NGAL as an AKI marker at different degrees of renal ischemia. METHODS Male C57BL/6J mice were subjected to 10-, 20- or 30-min unilateral renal ischemia, to control operation or no operation, and AKI was eval...
This study tested the hypothesis that combined therapy with exendin-4 (Ex4) and autologous adipose-derived mesenchymal stem cells (ADMSCs) was superior to either alone for protecting renal function against acute kidney ischemia-reperfusion (IR; 40-min ischemia/27-h reperfusion) injury when complicated by sepsis syndrome (SS; by cecal-ligation-puncture). Adult-male Sprague-Dawley rats (n=40) wer...
Cystathionine-beta-synthase (CBS) catalyzes the rate-limiting step in the transsulfuration pathway for the metabolism of homocysteine (Hcy) in the kidney. Our recent study demonstrates that ischemia-reperfusion reduces the activity of CBS leading to Hcy accumulation in the kidney, which in turn contributes to renal injury. CBS is also capable of catalyzing the reaction of cysteine with Hcy to p...
Linkermann et al. provide the first evidence for a possible biochemical mechanism of necrotic kidney cell death associated with renal ischemia/reperfusion-induced acute kidney injury. The mechanisms of several pathways resulting in programmed necrosis were recently elucidated and rely on receptor-interacting protein kinases 1 and 3. Using an inhibitor of one of these kinases, Linkermann et al. ...
Acute kidney injury is a leading contributor to morbidity and mortality in the ageing population. Proteotoxic stress response pathways have been suggested to contribute to the development of acute renal injury. Recent evidence suggests that increased synthesis of N-glycan precursors in the hexosamine pathway as well as feeding of animals with aminosugars produced in the hexosamine pathway may i...
Background: Ischemia/reperfusion induced acute renal failure causes excretory functional disorders of nephrons. Ischemia/reperfusion injury is accompanied by generation of reactive oxygen species that leads to dysfunction, injury, and death of renal cells. Antioxidants of plant origin minimize the harmful effects of reactive oxygen species. The aim of this study was to determine the possible th...
Ischemia and reperfusion have been a natural step during kidney transplantation. Impairment of blood flow starts with brain death due to severe hemodynamic disturbances in cadaveric donor. Clamping of renal artery causes an absolute ischemia during harvesting operation. Cold ischemia during allograft kidney storage may also cause additional ischemic damages (Southard et al. 1985; Ploeg et al.19...
Thrombotic microangiopathy (TMA) describes a pathological process of microvascular thrombosis, consumptive thrombocytopenia, and microangiopathic hemolytic anemia, leading to end-organ ischemia and infarction, affecting particularly the kidney and brain. TMA is a pathological feature of a number of clinical disorders including thrombotic thrombocytopenic purpura, hemolytic uremic syndrome, and ...
Ischemia Reperfusion injury is the tissue damage caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen. In this study, the effect of pentoxyfylline on BCL-2 gene expression changes and cell injury in kidney of rat following Ischemia Reperfusion were evaluated. In this experimental study, 20 male wistar rats with average weight of 250-300 g were selected and...
Vitamin D deficiency (VDD) increases the risk of death in hospitalized patients. Renal ischemia/reperfusion injury (IRI) induces acute kidney injury (AKI), which activates cell cycle inhibitors, including p21, a cyclin-dependent kinase inhibitor and genomic target of 25-hydroxyvitamin D, which is in turn a potent immunomodulator with antiproliferative effects. In this study, we assess the impac...
