Project description:Single-cell RNA sequencing analysis of lung tissue profiles of mice undergoing hepatic ischemia-reperfusion

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.

Project description:Hepatic ischemia-reperfusion IR (HIR) is an unavoidable pathophysiological process during liver transplantation, resulting in systematic sterile inflammation and remote organ injury. Acute lung injury (ALI) is a serious complication after liver transplantation with high postoperative morbidity and mortality. However, the underlying mechanism is still unclear. To assess the phenotype and plasticity of various cell types in the lung tissue microenvironment after HIR at the single-cell level, single-cell RNA sequencing (scRNA-seq) was performed using the lungs from HIR-induced mice.

Project description:Experimental Design: 1. The goal of the experiment: Age-Related Genome Expression Profiles During Hepatic Ischemia 2. Brief description of the experiment: Hepatic ischemia/reperfusion (I/R) injury is a complication of liver surgery, transplantation and shock and differs with age. In the present study, we sought to determine if the age-dependent response to I/R injury was related to differential gene expression during the ischemic period. Total RNA of young (4-5 weeks) and adult (12-14 months) mice undergoing sham surgery or partial hepatic ischemia for 30, 60, or 90 minutes was analyzed by Affymetrix microarray. Gene expression was filtered based on a change in expression of 1.5-fold relative to respective controls and then analyzed by ANOVA. Significant differences in gene expression were observed between age groups. In young mice, 169 genes were down-regulated, whereas adult mice had 1167 genes down-regulated. Of these, only 28 genes were down-regulated in both young and adult mice. Far fewer genes had increased expression during ischemia. Sixty genes in young mice and 51 genes in adult mice were up-regulated. Of those, none were up-regulated in both young and adult mice. There were no distinct functional patterns of gene regulation in either age group. The data demonstrate significant and widespread changes in hepatic gene expression during the ischemic period that may be important to the age-dependent response to I/R injury. Keywords: treated vs non treated 2 age groups of 12 young and 12 adult mice that underwent either 30, 60 or 90 minutes of partial ischemia (n=3) or sham operation (n=3) We used microarray to uncover the genomic response during different time points of ischemia

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.
