Experimentally, females show an improved ability to recover from ischemia-reperfusion injury (IRI) compared with males; however, this sex-dependent response is less established in humans. Here, we developed a series of murine renal ischemia and transplant models to investigate sex-specific effects on recovery after IRI. We found that IRI tolerance is profoundly increased in female mice compared...

Warm renal ischemia performed during partial nephrectomy has been found to be associated with kidney disease. Since endogenous ouabain (EO) is a neuro-endocrine hormone involved in renal damage, we evaluated the role of EO in renal ischemia-reperfusion injury (IRI). We measured plasma and renal EO variations and markers of glomerular and tubular damage (nephrin, KIM-1, Kidney-Injury-Molecule-1,...

OBJECTIVES Ischemia-reperfusion injury (IRI) is a major cause of acute kidney injury and chronic kidney disease. Two promising preconditioning methods for the kidney, intermittent arterial clamping (IC) and treatment with the hypoxia mimetic cobalt chloride, have never been directly compared. Furthermore, the protective efficacy of the chemically related transition metal Zn2+ against renal IRI ...

Ischemia-reperfusion injuries (IRI) occur in different clinical conditions such as stroke, trauma, organ transplantation, and so on. Ischemia damages mainly arise from oxygen depletion in tissues. The lack of oxygen as the last acceptor of electron in the respiratory chain causes a decrease in ATP production and eventually leads to disruption of membrane transport, acidosis, cellular edema and ...

Ischemic renal injury can be classified into the initiation and extension phase followed by the recovery phase. The recovery phase is characterized by increased dedifferentiated and mitotic cells in the damaged tubules. Suppression subtractive hybridization was performed by using RNA from normal and ischemic kidneys to identify the genes involved in the physiological response to ischemia-reperf...

Introduction: Using brief episodes of ischemia and reperfusion (IR) prior to a more sustained IR insult – ischemic preconditioning (IPC) – can reduce IR injury of the heart, brain and many other tissues. The purpose of present study was to investigate the effect of 2min ischemic periods on subsequent rat renal IR injury. Methods: Male rat's renal IR injury was investigated in a right nephrectom...

Kidney damage due to ischemia-reperfusion injury (IRI) is a serious cause of morbidity and mortality. We induced an experimental kidney model in rats where intraperitoneal dexpanthenol were given compared controls terms oxidative stress, tubular damage, apoptosis, its effect on renal inflammation. Twelve-week-old male albino Wistar used for creating the study sample divided into three groups (n...

Chromatin regulators (CRs) are essential upstream regulatory factors of epigenetic modification. The role CRs in the pathogenesis renal ischemia-reperfusion injury (IRI) remains unclear. We analyzed a bioinformatic analysis on differentially expressed chromatin regulator genes IRI patients using data from public domains. hub identified were used to develop risk prediction model for IRI, and the...

Objective(s)Ischemia-reperfusion injury (IRI) is a leading cause of kidney transplantation failure, and ischemic-preconditioning (IPC) is a protective method against the IRI. In the present study, the defensive effect of IPC on rats’ kidney was investigated and more importantly the differences between two genders were appraised.Materials and MethodsThirty two Wistar rats were randomly allocated...

Renal ischemia-reperfusion injury (IRI) is the leading cause of acute kidney injury [AKI; acute renal failure (ARF)] in native kidneys and delayed graft function in deceased donor kidney transplants. Serum creatinine rises late after renal IRI, which results in delayed diagnosis. There is an important need to identify novel biomarkers for early diagnosis and prognosis in renal IRI. Given the in...
