Analysis of changes in the BLA and vmPFC brain region of control mice and global cerebral ischemia mice after acute stress

Project description:It is known that the eCB 2-AG is synthesized in postsynaptic cells and released into synaptic clefts when needed. As we observed that acute stress prominently increased eCBs in vmPFC-BLA synapses and that inhibited expression of 2-AG synthase gene Dagla in vmPFC-BLA synapses blocked stress-induced PGCID, we plausibly hypothesized that transient GCI increased 2-AG biosynthesis in BLA neurons, leading to stress-induced increase of 2-AG release into vmPFC-BLA synapses. To test this hypothesis, we employed single-cell sequencing to examine whether GCI mice, in comparison with sham mice, showed increased mRNA expression of the Dagla in c-fos positive BLA and vmPFC cells of acute stress-treated mice

phosphoproteome of hippocampus after focal cerebral ischemia 1.5 h and reperfusion 24 h in mice

Project description:We obtained the profiles of neuronal phosphoproteome after cerebral ischemia and reperfusion by isolating mice hippocampus. Hippocampus combined from either nine sham or nine focal cerebral ischemia 1.5 h and reperfusion 24 h (IR) mice were lysed, digested, labeled with different TMT tags, then pooled and analyzed by LC/LC-MS/MS. In total, we quantified 7,865 phosphopeptides,179 phosphorylation sites of 129 proteins were upregulated and 843 phosphorylation sites of 494 proteins were downregulated in hippocampus during cerebral ischemia 2 h compare with sham operation.

Proteome and phosphoproteome of hippocampus after focal cerebral ischemia 2 h in mice

Project description:We obtained the profiles of neuronal phosphoproteome after cerebral ischemia onset by isolating mice hippocampus. Hippocampus combined from either ten sham or ten focal cerebral ischemia 2 h mice were lysed, digested, labeled with different TMT tags, then pooled and analyzed by LC/LC-MS/MS. Five percent of the pool was used for whole proteome analysis, and the remaining 95% was subjected to phosphoproteome profiling. In total, we quantified 5,174 proteins and 9,062 phosphopeptides. Interesting, 21 proteins were upregulated and 7 proteins were downregulated in hippocampus lysates of cerebral ischemia 2 h relative to sham base on fold change. S100a9, Alpha-2-HS-glycoprotein (Ahsg), Fibrinogen beta chain (Fga) and Complement Component C3(c3) are the top significantly changed, which were highly consistent with previous reports in cerebral ischemia injury. Using wolfpsort software to analysis the Subcellular Location, 57% of detected proteins were location to extracellular, 15% were cytoplasmic protein, another 11% were transport to nucleus, and the others were location to plasma membranes (10%), mitochondria (4%) and endoplasmic reticulum (3%). Moreover,184 phosphorylation sites of 135 proteins were upregulated and 689 phosphorylation sites of 420 proteins were downregulated in hippocampus during cerebral ischemia 2 h compare with sham operation. Employing wolfpsort software analysis the subcellular location, 50% of phosphorylated proteins were location to nucleus, 26% were cytoplasmic protein, another 16% were transport to plasma membranes, and the others were location to mitochondria (4%), extracellular (3%) and cytoskeleton (1%). Motif analysis showed that 85% were belongs to serine-type phosphorylation, about 14 were threonine-type phosphorylation and 1% were tyrosine-type phosphorylation.

Mouse brain LC-MS data in DWI-T2 mismatch area after cerebral ischemia

Project description:In ischemic stroke, DWI-T2 mismatch (positive signals on DWI but negative signals on T2) indicates ischemia within 4.5 h. However, the molecular expression pattern of this region remains elusive. This project aimed to reveal the proteomics profiling of the brain tissues at DWI-T2 mismatch, T2(+), and contralateral regions of brain within 4.5 h after middle cerebral artery occlusion compared with naïve brains of mice.

Proteome of hippocampus after focal cerebral ischemia 1.5 h and reperfusion 24 h in mice

Project description:We obtained the profiles of neuronal proteome after cerebral ischemia and reperfusion by isolating mice hippocampus. Hippocampus combined from either nine sham or nine focal cerebral ischemia 1.5 h and reperfusion 24 h (IR) mice were lysed, digested, labeled with different TMT tags, then pooled and analyzed by LC/LC-MS/MS. In total, we quantified 5,059 proteins. We identified 142 differentially expressed proteins (t-test, p-value<0.05) after IR compared to sham groups. The results showed that 92 proteins were upregulated, and 50 proteins were downregulated after IR compared to sham groups. Gene ontology (GO) enrichment analysis of differentially expressed proteins between sham and IR groups. The results showed that the biological process of most of upregulated genes linked with immune inflammatory related responses were increased. And KEGG pathway analysis for upregulated genes showed that multiple immune inflammatory response pathways also increased significantly, such as TNF-signaling, NF-κB signaling and cytokine-cytokine receptor interaction, as well as NOD-like receptor signaling, and toll-like receptor signaling.

Effect of Celastrol on LncRNAs and mRNAs Profiles of Cerebral Ischemia-Reperfusion Injury in Transient Middle Cerebral Artery Occlusion Mice Model

Project description:Celastrol plays a significant role in cerebral ischemia-reperfusion injury. Although previous studies have confirmed that celastrol post-treatment has a protective effect on ischemic stroke, the therapeutic effect of celastrol on ischemic stroke and the underlying molecular mechanism remain unclear. In the present study, focal transient cerebral ischemia was induced by transient middle cerebral artery occlusion (tMCAO) in mice and celastrol was administered immediately after reperfusion. We performed lncRNA and mRNA analysis in the ischemic hemisphere of adult mice with celastrol post-treatment through RNA-Sequencing (RNA-Seq). A total of 50 differentially expressed lncRNAs (DE lncRNAs) and 696 differentially expressed mRNAs (DE mRNAs) were identified between the sham and tMCAO group, and a total of 544 DE lncRNAs and 324 DE mRNAs were identified between the tMCAO and tMCAO+celastrol group. Bioinformatic analysis was done on the identified deregulated genes through gene ontology (GO) analysis, KEGG pathway analysis and network analysis. Pathway analysis indicated that inflammation-related signaling pathways played vital roles in the treatment of ischemic stroke by celastrol. Our study suggests celastrol treatment can effectively reduce cerebral ischemia-reperfusion injury. The bioinformatics analysis of lnRNAs and mRNAs profiles in the ischemic hemisphere of adult mice provides a new perspective in the neuroprotective effects of celastrol, particularly with regards to ischemic stroke.
