METTL3 deficiency aggravates hepatic ischemia/reperfusion injury in mice by activating the MAPK signaling pathway

ABSTRACT: Inflammatory responses, apoptosis, and oxidative stress, are key factors that contribute to hepatic ischemia/reperfusion (I/R) injury, which may lead to the failure of liver surgeries, such as hepatectomy and liver transplantation. The N6-methyladenosine (m6A) modification has been implicated in multiple biological processes, and its specific role and mechanism in hepatic I/R injury require further investigation. We found that METTL3 may be involved in regulating this process. Therefore, we constructed an ischemia-reperfusion model with Hepatocyte-specific METTL3 knockdown (HKD) mice, and performed RNA- sequencing analysis with wild-type mice as controls.

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.

Expression data from lung tissues of minipig with left lung ischemia-reperfusion

Project description:Lung ischemia-reperfusion (I/R) injury remains one of the common complications after various cardiopulmonary surgeries. I-R injury represents one potentially maladaptive response of the innate immune system which is featured by an exacerbated sterile inflammatory response triggered by tissue damage. Thus, understanding the key components and processes involved in sterile inflammation during lung I-R injury is critical to alter care and extend survival for patients with acute lung injury. We constructed a minipig surgical model of transient unilateral left pulmonary artery occlusion without bronchial involvement to create ventilated lung I-R injury. Lung tissues from minipig with sham operation (one sample), left side lung tissues (the operated side)(one sample) and right side lung tissues (the non-operated side)(one sample) from minipig with lung ischemia-reperfusion were submitted for gene expression array analysis.

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.

Gene expression profiles of mouse ischemia-reperfusion liver zones with or without celastrol-treated.

Project description:Hepatic ischemia-reperfusion (I/R) has long affected the success rate of liver transplant. Though zone-specific injury induced by I/R was observed, elaborated cellular and molecular mechanisms underlying the I/R injury pattern have not been revealed. Spatial transcriptomics analysis has great potential to uncover the mechanisms of liver I/R injury.
