Vascular Permeability and Apoptosis are Separable Processes in Retinal Ischemia-Reperfusion Injury

ABSTRACT: Effects of Ischemic Preconditioning, Bevacizumab and Etanercept Ischemia and reperfusion injury provides an acute model of ischemic retinopathy that includes neurodegeneration and VEGF-dependent vascular permeability and is amenable to rapid drug testing. The distinct effects of ischemic preconditioning and bevacizumab demonstrate that the apoptotic and vascular responses to ischemia may be separated and that VEGF expression is not neuroprotective following ischemic-reperfusion.

Vascular Permeability and Apoptosis are Separable Processes in Retinal Ischemia-Reperfusion Injury

Project description:Effects of Ischemic Preconditioning, Bevacizumab and Etanercept Ischemia and reperfusion injury provides an acute model of ischemic retinopathy that includes neurodegeneration and VEGF-dependent vascular permeability and is amenable to rapid drug testing. The distinct effects of ischemic preconditioning and bevacizumab demonstrate that the apoptotic and vascular responses to ischemia may be separated and that VEGF expression is not neuroprotective following ischemic-reperfusion. Using transient ischemia followed by reperfusion (IR) to model ischemic retinal disease, this study compares the effects of ischemic preconditioning (IPC) and therapies targeting vascular endothelial growth factor (VEGF) and tumor necrosis factor α (TNFα) on retinal apoptosis, vascular permeability and mRNA biomarker expression. Only the Ischemic Preconditioning (not Bevacizumab and Etanercept treated samples) were hybridized to arrays. Study contains 6 replicates of control and 6 IP treated retinal samples.

small RNA-Seq of rat kidney in a model of ischemic preconditioning/ischemia-reperfusion injury

Project description:Ischemic preconditioning is effective in limiting subsequent ischemic acute kidney injury in experimental models. microRNAs are an important class of post-transcriptional regulator and show promise as biomarkers of kidney injury. An evaluation was performed of the time- and dose-dependent effects of ischemic preconditioning in a rat model of functional (bilateral) ischemia-reperfusion injury. A short, repetitive sequence of ischemic preconditioning resulted in optimal protection from subsequent ischemia-reperfusion injury. A detailed characterization of microRNA expression in ischemic preconditioning/ischemia-reperfusion injury was performed by small RNA-Seq.

Genome-wide profiling of cardiac H3K9me2 levels in response to ischemic preconditioning

Project description:H3K9me2 ChIP-Seq of cardiac biopsies from the area at at risk and remote myocardium of mice subjected to ischemic preconditioning. Mice were subjected to ischemic preconditioning (IPC) through reversible ligation of the left coronary artery or a sham procedure. The procedure consisted of 5 minutes of ischemia followed by 5 minutes of reperfusion, repeated 4 times and then followed by a 30 minute reperfusion period. Biopsies were taken from the area at risk (AAR) and remote myocardium (RM) from six IPC mice

Transcriptomic profiling of cardiac biopsies from mice subjected to ischemic preconditioning

Project description:Microarray profiling of cardiac biopsies from the area at at risk and remote myocardium of mice subjected to ischemic preconditioning. Mice were subjected to ischemic preconditioning (IPC) through reversible ligation of the left coronary artery or a sham procedure. The procedure consisted of 4 minutes of ischemia followed by 4 minutes of reperfusion, repeated 4 times and then followed by a 30 minute reperfusion period. Biopsies were taken from the area at risk (AAR) and remote myocardium (RM) from two IPC mice and two sham control mice.

The analysis of differential gene expression after remote ischemic preconditioning of renal ischemia reperfusion injury

Project description:To investigate the mechanism by which ischemic preconditioning (IPC) produces tissue tolerance to renal ischemia reperfusion injury in a pig model 15 female Yorkshire pigs were divided into three groups: 1: no IPC and 90 minutes warm ischemia; 2: remote IPC with an early window followed by 90 min warm ischemia; 3: remote IPC with a late window followed by warm ischemia 24 hrs later. Kidney tissues were obtained after 72 hours.
