Background & Target: 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 bcl2 gene expression changes and cell injury in kidney of rat following Ischemia Reperfusion were evaluated.Methods: In this experimental study, 20 male wistar rats with average weight of...
We have previously shown that expression of renal organic anion transporters Oat1 and Oat3 is diminished by prostaglandin E(2) (PGE(2)) and that both transporters are downregulated after renal ischemia. Because PGE(2) is increased after renal ischemia and is generated by cyclooxygenases (COX), we investigated the effect of the COX inhibitor indomethacin on expression of Oat1/3 after ischemic ac...
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...
renal ischemia-reperfusion (ir) injury is a common problem in kidney transplantation. there is increasing evidence about the role of the reactive oxygen species (ros) in these injuries and endogenous antioxidants seem to have an important role in decreasing the renal tissue injury. the aim of this study was to investigate the effects of kidney ir on renal antioxidant enzymes activity such as ca...
Ischemia/reperfusion injury associated with kidney transplantation induces profound acute injury, influences early graft function, and affects long-term graft outcomes. To determine whether renal dendritic cells play any role during initial innate ischemia/reperfusion injury and the subsequent development of adaptive immune responses, we studied the behavior and function of renal graft and host...
Our findings demonstrate the pivotal importance of caspase-3 in regulating renal microvascular dysfunction, fibrogenesis, and long-term impairment after acute kidney injury induced by ischemia-reperfusion injury. Furthermore, this study establishes predominant role peritubular capillary integrity as a major contributor to progressive dysfunction

Acute renal failure (ARF) severely worsens prognosis of hospitalized patients. The most frequent cause of intrarenal ARF is transient or prolonged renal hypoperfusion (ischemia). Ischemia primarily affects the function and structure of tubular epithelial cells, which, in severe cases, is characterized by epithelial cell necrosis. Nevertheless, ischemia does not exclusively lead to alterations o...
Mesenchymal stem cells (MSCs) are a potential therapeutic tool for preventing the progression of acute kidney injury (AKI) to chronic disease (CKD). Herein, we investigated localization and maintenance engrafted human bone marrow-derived MSCs in rats subjected renal ischemia-reperfusion (IRI) compared effectiveness two intravascular injection routes via artery or inferior vena cava. Renal was m...
Curcumin, a component of the spice turmeric, was shown to have a protective effect on acute kidney injury markers following ischemia-reperfusion injury (IRI). However, its effect on glomerular and tubular renal functions following IRI is not known and this data is probably of more clinical relevance. In this study, curcumin was tested for its effect on renal functional parameters following two ...
