Transcriptome analyses of cerebral ischemia reveal functional lncRNAs in ischemia stroke

Project description:Background and Purpose: Long noncoding RNAs (lncRNAs) are an emerging class of genomic regulatory molecules reported in neurodevelopment and many diseases. Despite extensive studies have identified lncRNAs and discovered their functions in CNS diseases, the function of lncRNAs in ischemia stroke remains poorly understood. Method: Ischemia was induced by transient middle cerebral artery occlusion. Expression profiles of lncRNAs, miRNAs and mRNAs after ischemia stroke were obtained using high throughput sequencing technology. A correlation network was constructed to predict lncRNA functions. LncRNA-miRNA-mRNA network was constructed to discover ceRNAs. Results: 1924 novel lncRNAs were identified, indicating that the ischemia stroke has a complex effect on lncRNAs. The top 10 regulated lncRNAs was validated by qRT-PCR. We have also predicted function of lncRNAs, and subjected them to gene co-expression network analysis, revealing the involvement of lncRNAs in many important biological process including injury and repair that are implicated in the regulation of ischemia stroke. Furthermore, lncRNAs mediated SMD (Staufen1-mediated mRNA decay) was analyzed and ceRNA (competitive endogenous RNAs) network was constructed in ischemia stroke. Conclusions: This study reports the genome-wide lncRNA profiles in ischemia stroke using high throughput sequencing and constructs a systematic lncRNA-miRNA-mRNA network which reveals a complex functional noncoding RNA regulatory network in ischemia stroke.

Photothrombotic Cerebral Stroke as a Model of Post-Stroke Seizures/Epilepsy in aged mice

Project description:Stroke is a prevalent disorder representing the third leading cause of death and major cause of disability. Post-stroke epilepsy (PSE) has been recognized as a common clinical issue after stroke, accounting for 30-40% of the causes of epilepsy among older adults. In this study, we determined GABAA receptor-mediated seizure susceptibility after PT cerebral stroke in aged mice. Young adult mice around 10 weeks of age are widely used in stroke experiments. However, as most strokes are diagnosed in the elderly and PSE has been recognized as a common clinical incidence after stroke, we utilized photothrombosis (PT) model of cerebral ischemia and examined seizure susceptibility and brain injury using combined behavioral (video) and EEG monitoring and histological (MRI) assessments. To investigate GABAA receptor-mediated convulsive/non-convulsive seizures, lower-doses of pentylenetetrazol (PTZ) was injected. PTZ susceptibility in aging mice increased compared to young adults. One month after PT stroke, aged PT stroke mice exhibited severe convulsive seizures (late-onset). These findings exhibited the increase of GABAA receptor-mediated seizures susceptibility in PT stroke aging mice, but not in young adults.

Acid sphingomyelinase deactivation post-ischemia/ reperfusion promotes cerebral angiogenesis and brain remodeling via small extracellular vesiclesAcid sphingomyelinase deactivation post-ischemia/ reperfusion promotes cerebral angiogenesis and brain remodeling via small extracellular vesicles

Project description:Acid sphingomyelinase (ASM) inhibitors, which are clinically used as anti-depressants for ~60 years, have recently been shown to enhance stroke recovery in rodents. Using mice and cerebral microvascular endothelial cells exposed to ischemia/reperfusion (I/R) we show that the antidepressants amitriptyline, fluoxetine and desipramine induce angiogenesis in an ASM-dependent way by releasing small extracellular vesicles (sEVs) from endothelial cells, which have bona fide characteristics of exosomes and which, similar to sEVs released during I/R, promote angiogenesis. Post-I/R, ASM inhibition elicits a profound brain remodeling response with increased blood-brain barrier integrity, reduced brain leukocyte infiltrates and increased neuronal survival. The ASM inhibitor-mediated release of sEVs has disclosed an elegant target, via which stroke recovery can be amplified.

Proteomic analysis of focal cerebral ischemia/reperfusion injury in rats

Project description:Stroke is a leading cause of mortality and long-term disability and ischemic stroke accounts for 87% of all strokes. Though timely recanalization of the occluded vessel is essential in the treatment of ischemic stroke, it is well known to cause ischemia-reperfusion (I/R) injury which result in neuronal cell death, brain tissue loss and severe neurological deficits. In this work, we employed a global proteomic approach to examine the changes of cerebral cortex proteins in rats undergoing acute and long-term I/R injury. In vivo middle cerebral artery occlusion (MCAO) model of focal cerebral I/R injury in rats was established. The animals were divided into three model groups with 2 h-MCAO followed with different reperfusion time, 1 day, 7 days and 14 days, respectively. For each model group a sham group was correspondingly set. Each group included four animals. For proteomic analysis, cerebral cortex proteins were extracted and analyzed by SDS-PAGE, whole-lane slicing, in-gel digestion and label-free quantitative LC-MS/MS. A total of 5621 proteins were identified and their quantities between the surgery and corresponding sham groups and across the three reperfusion time points were compared for mechanism investigation. This dataset includes all the raw files of the 840 LC-MS runs (6 groups x 4 animals x 35 gel squares/sample), as well as their identification and quantitation results at the levels of peptide fragments, peptides and proteins, respectively.
