Transcription profiling of rat NRVMs response to ischemia and reperfusion events using Coverslip Hypoxia

ABSTRACT: NRVMs were subjected to varying durations of ischemia or ischemia+reperfusion using coverslip hypoxia. Expression profiling was used to identify genes that are differentially regulated in either event. We used microarrays to detail the global program of gene expression underlying ischemia and reperfusion using Coverslip Hypoxia and identified distinct classes of genes regulated during these processes. Experiment Overall Design: RNA was extracted from NRVMs subjected to varying durations of ischemia or ischemia+reperfusion and hybridized to rat genome Affymetrix arrays.

Gene Expression Changes due to Rat Lung Ischemia-Reperfusion Injury

Project description:Ischemia-reperfusion injury (IRI) is a major cause of morbidity and mortality following conventional lung transplantation and warm ischemia may limit success of transplanting lungs from non-heart-beating donors. We sought to determine alterations in gene expression in rat lung tissue subjected to warm ischemia in vivo followed by reperfusion. Keywords: time course

KLF6 alleviates hepatic ischemia-reperfusion injury by inhibiting autophagy

Project description:To find the genes with significant expression changes after liver ischemia-reperfusion injury,we established a hypoxia-reoxygenation model using AML12 cells. We then performed gene expression profiling analysis using data obtained from RNA-seq under normoxia and hypoxia-reoxygenation conditions.

Intralipid protects the heart in late pregnancy against ischemia/reperfusion injury

Project description:The heart of late pregnant (LP) rodents is more prone to ischemia/reperfusion (I/R) injury compared to non-pregnant rodents. We hypothesized that Intralipid (ITLD) protects the heart in LP rodents against I/R injury. We performed genome-wide expression profiling to identify the underlying mechanisms. Female LP rat hearts were subjected to ischemia followed by reperfusion with vehicle or ITLD (one bolus of 5mg/kg).

RealTime quantitative PCR of cardiac at risk area samples obtained from a mouse model of ischemia and reperfusion injury

Project description:Mice were exposed to cardiac ischemia/reperfusion injury and sacrificed after 1 or 4 days. Hearts were stained with Evans blu/TTC to isolate the at risk area. Hearts were divided into 1mm slices, the at risk area of any slice were pooled together before RNA extraction. Mice were divided into 3 different groups: Sham animals have been subjected to the surgical procedure without the induction of the ischemia and reperfusion injury and represent the control animals; LAD group is represented by animals subjected to the surgical procedure and the induction of the ischemia and reperfusion imjury; MLAD group is represented by animals subjected to the surgical procedure and the induction of the ischemia and reperfusion injury, followed by myriocin treatment (SLN/Myr) at the beginning of reperfusion.

Global microRNA expression profiling of mouse livers following ischemia-reperfusion injury at different stages. [miRNA]

Project description:Hepatic ischemia reperfusion injury is a dynamic process consisting of two stages: ischemia and reperfusion, and triggers a cascade of physiological and biochemical events. Given the important role of microRNAs in regulating gene expression, we analyzed gene expression changes in mouse livers at sham control, ischemia stage, and reperfusion stage. We generated global expression profiles of microRNA and mRNA genes in mouse livers subjected to ischemia reperfusion injury at the three stages, respectively. Comparison analysis showed that reperfusion injury had a distinct expression profile whereas the ischemia sample and the sham control were clustered together. Consistently, there are 69 differentially expressed microRNAs between the reperfusion sample and the sham control whereas 28 differentially expressed microRNAs between the ischemia sample and the sham control. We further identified two modes of microRNA expression changes in ischemia reperfusion injury. Functional analysis of both the differentially expressed microRNAs in the two modes and their target mRNAs revealed that ischemia injury impaired mitochondria function, nutrient consumption, and metabolism process. In contrast, reperfusion injury led to severe tissue inflammation that is predominantly an innate-immune response in the ischemia reperfusion process. Our staged analysis of gene expression profiles provides new insights into regulatory mechanisms of microRNAs in mouse hepatic ischemia reperfusion injury.

Ischemic Pre- and Post Conditioning has pronounced effects on Gene Expression Profiles in the Rat Liver after Ischemia/Reperfusion

Project description:Ischemia/reperfusion injuries is a known complication to hepatic surgery. Ischemic pre- (IPC) and postconditioning (IPO) protects the liver against ischemia/reperfusion-injuries. Expression profiling were performed on liver biopsies seeking to identify molecular mediators of the protective properties. 48 rats were divided into 5 groups; sham (n=8), IRI (n=10), IPC (n=10), IPO (n=10) and IPC+IPO (n=10). All rats except sham rats were subjected to 30 min of total liver ischemia and 30 min of reperfusion before liver biopsies were sampled. In the IPC group, liver ischemia was preceded by 10 min of hepatic ischemia, followed by 10 min of reperfusion. IPO were performed by three cycles of 30 sec of reperfusion and 30 sec of ischemia, applied immediately after the 30 min of total liver ischemia. In the IPC+IPO group the two interventions were combined.

Differential expression of mRNAs in the heart of ischemia-reperfusion mice

Project description:To identify the role of mRNA during myocardial ischemia-reperfusion in mice, we have employed high-throughput sequencing to detect mRNA expression. Samples were collected from the control group and the ischemia reperfusion groups , with 5 samples per group. The candidate mRNA that may affect the process of myocardial ischemia-reperfusion was screened by comparing the ischemia-reperfusion group and the control group.
