RNA sequencing of ipsilateral cortex after transient focal ischemia in mice

ABSTRACT: We report the application of Illumina paired-end RNA-seq approach for transcriptome of brain tissue in mice. By removing sequence-dependent bias and amplification noise using UMI-tools. The mapped reads of each sample were assembled using StringTie. After the final transcriptome was generated, StringTie and edgeR was used to estimate the expression levels of all transcripts. By obtaining a total of million paired-end reads of sequence from cerebral cortex tissue, we generated transcriptome profiles of mouse ischemic cortex in sham, 24 h after focal ischemia, 28 d after focal ischemia, with or without neuron-specific knockdown of TIPARP, respectively. We found 2017 differentially expressed genes (DEGs) between Sham+AAV-SYN-shRNA-Con and tMCAO+AAV-SYN-shRNA-Con group, and 516 DEGs between tMCAO+AAV-SYN-shRNA-Con and tMCAO+AAV-SYN-shRNA-TIPARP group at 24 h after stroke. In addition, we found 487 DEGs between Sham+AAV-SYN-shRNA-Con and tMCAO+AAV-SYN-shRNA-Con group, and 192 DEGs between tMCAO+AAV-SYN-shRNA-Con and tMCAO+AAV-SYN-shRNA-TIPARP group at 28 d after stroke. This study provides a detailed analysis of the underlying mechanisms of neuron-specific knockdown of TIPARP in neuronal injury and long-term effect, with biologic replicates, generated by RNA-seq technology.

RNA sequencing analysis Reveal Post-Stroke Cognitive Impairment related genes in Hippocampus of Cerebral Ischemic Rat

Project description:In summary, a comprehensive bioinformatics analysis of the possible DEGs and pathways involved in tMCAO rats with cognitive impairment and Sham rats was conducted. DEGs, such as Acta2, Calb2, Cxcl12, as well as the intestinal immune and steroid biosynthesis may play a pivotal role in mechanism of PSCI.

Profiling brain cortex from tMCAO rat stroke model

Project description:This program addresses the gene signature associated with brain (cortex) in the tMCAO rat model for stroke. The tMCAO stroke model profiling data was analyzed by identifying genes that were up- and down-regulated at selected p value and fold change in brain cortex of the Sprague Dawley rats following middle cerebral artery occlusion compared to the sham-operated controls.

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.

Effect of pivalate-induced secondary carnitine deficiency on hepatic transcriptome and plasma metabolome in growing pigs

Project description:Administration of pivalate has been demonstrated to be suitable for induction of secondary car-nitine deficiency (CD) in pigs, as model objects for humans. In order to comprehensively charac-terize the metabolic effects of secondary CD in the liver of pigs, the present study aimed to carry out comparative analysis of hepatic transcriptome and plasma metabolome of a total of 12, male 5-weeks-old pigs administered either pivalate (group PIV, n = 6) or vehicle (group CON, n = 6) for 28 days. Pigs of group PIV had approximately 40-60% lower concentrations of free carnitine and acetylcarnitine in plasma, liver and different skeletal muscles than pigs of group CON (p < 0.05). Transcript profiling of the liver revealed 140 differentially expressed genes (DEGs) between group PIV and group CON (fold change > 1.2 or < −1.2, p-value < 0.05). Biological process terms dealing with the innate immune response were found to be enriched with the DEGs (p < 0.05). Using a targeted metabolomics approach for the simultaneous quantification of 630 metabolites, 13 me-tabolites were identified to be lower and 5 metabolites to be higher in group PIV than in group CON (p < 0.05). Despite pivalate-induced CD caused only weak alterations of the hepatic tran-scriptome and the plasma metabolome, the changes observed indicate that secondary CD modu-lates the innate immune response of pigs.

Stroke-induced transcriptomic alterations in mouse cerebral microvessels

Project description:To investigate the stroke-induced changes in gene expression in cerebral microvessels, we subjected mice to transient middle cerebral artery occlusion (tMCAO) or sham surgeries. 24h hours later, cerebral microvessels were harvested and RNA was isolated. We then performed gene expression profiling analysis using data obtained from RNA-seq of cerebral microvessels isolated from 8 mice (4 shams and 4 tMCAO)

The role of Clec4e (Mincle) in microglia response to transient ischemic injury

Project description:This data set shows dramatic changes in gene expression in microglia isolated from C57Bl6/J mice subjected to transient middle cerebral artery occlusion, as compared to those subjected to sham surgery. Mice deficient in Mincle (Clec4e-/-) showed significantly improved injury outcomes 3 and 7 days after transient middle cerebral artery occlusion. However, when comparing changes in gene expression in microglia 24 hours after blood reperfusion, there were no differences between wild-type and Clec4e-/- mice, indicating that Mincle does not participate in early microglial activation. Wild type and Mincle knock-out (Clec4e-/-) mice. After 1 h of transient middle cerebral artery occlusion (tMCAO) and 24 h of reperfusion, mice were perfused with PBS, their brains dissected, and 2 ipsilesional hemispheres (with cerebellum and brainstem removed) pooled for microglia isolation. For sham-operated animals, the whole forebrain was used and brains were not pooled. After myelin separation by Percoll gradient centrifugation, around 80,000 CD45intermediate, CD11b+ microglial cells were sorted from each sample. Sham samples n=3, tMCAO samples n=5.

HDAC4 gene therapy

Project description:Black six animals received either an Adeno associated virus leading to overexpression of Luciferase or Histone deacetyase 4 aminoacids 1-201. After 3 weeks of expression, animals got transaortic banding (TAC) to induce pathological cardiac remodeling. We compared both groups to Back six animals with sham surgery and overexpression of Luziferase. 3 male animals per group (5 replicates) at an age of 8 weeks were treated with an adenoassociated virus (AAV) containing a coding sequence for Luziferase or Histone Deacetylase 4 (aminoacids 1-201) und der the control of the MLC-promoter. Both groups were then exposed to transaortic constriction. As a control served AAV treated animals with overepression of luziferase and sham.
