Mitochondria have long been known to be the gatekeepers of cell fate. This is particularly so in the response to acute ischaemia-reperfusion injury (IRI). Following an acute episode of sustained myocardial ischaemia, the opening of the mitochondrial permeability transition pore (MPTP) in the first few minutes of reperfusion, mediates cell death. Preventing MPTP opening at the onset of reperfusi...

T cells have been implicated in the early pathogenesis of ischemia reperfusion injury (IRI) of kidney, liver, lung, and brain. It is not known whether Ag-TCR engagement followed by Ag-specific T cell activation participates in IRI. T cell-deficient nu/nu mice are moderately resistant to renal IRI, which can be reversed upon reconstitution with syngeneic T cells. In this study, we found that nu/...

Hepatic ischemia and reperfusion injury (IRI) is an inflammatory condition and a significant cause of morbidity and mortality after surgery. Matrix metalloproteinases (MMPs) have been widely implicated in the pathogenesis of inflammatory diseases. Among the different MMPs, gelatinases (MMP-2 and MMP-9) are within the most prominent MMPs detected during liver IRI. While the role of MMP-9 in live...

Acute kidney injury (AKI) and autosomal dominant polycystic kidney disease (ADPKD) are considered separate entities that both frequently cause renal failure. Since ADPKD appears to depend on a polycystin-1 (Pc1) or Pc2 dosage mechanism, we investigated whether slow progression of cystogenesis in two Pkd1 transgenic mouse models can be accelerated with moderate ischemia-reperfusion injury (IRI)....

Human liver ischemia/reperfusion injury (IRI) is a common and major clinical problem complicating liver surgery and transplantation. The pathogenesis underlying IRI is complex, involving a series of signaling mediators and mechanisms. This study aimed to investigate the effects of Magnesium Isoglycyrrhizinate (MgIG) on the changes of oxidant stress and apoptosis induced by IRI in human hepatic ...

PURPOSE To investigate the potential beneficial effect of silibinin in ischemia-reperfusion injury (IRI) of skeletal muscle. METHODS Under urethane anesthesia, four experimental groups were established in Balb/c mice: I) Sham-control, II) IRI (Tourniquet-induced) (2+1 h), III) IRI+ethanol (10%), and IV) IRI+silibinin (50 mg/kg/IP). The viability of muscle (left) was evaluated by the triphenyl...

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...

BACKGROUND Renal ischemia-reperfusion injury (IRI) increases the rates of acute kidney failure, delayed graft function, and early mortality after kidney transplantation. The pathophysiology involved includes oxidative stress, mitochondrial dysfunction, and immune-mediated injury. The anti-oxidation, anti-apoptosis, and anti-inflammation properties of baicalin, a flavonoid glycoside isolated fro...

Renal ischaemia reperfusion injury (IRI) is a common cause of acute kidney injury (AKI) in patients and occlusion of renal blood flow is unavoidable during renal transplantation. Experimental models that accurately and reproducibly recapitulate renal IRI are crucial in dissecting the pathophysiology of AKI and the development of novel therapeutic agents. Presented here is a mouse model of renal...
