Epigenome analysis of normal and ischemic stroke patients blood samples

Project description:Genome wide DNA methylation profiling of normal and ischemic stroke patients blood samples. The Illumina Infinium 850k Human DNA methylation Beadchip was used to obtain DNA methylation profiles across approximately 850,000 CpGs in liquid. Samples included 3 healthy people blood samples, 3 ischemic stroke patients blood samples.

Epigenome analysis of ischemic stroke patients

Project description:We performed a genome-wide methylation study in whole-blood DNA from 404 ischemic stroke patient cohort, distributed across 3 ischemic stroke subtypes: Large-artery atherosclerosis (n=132), Small-artery disease (n=141) and Cardio embolic (n=127) . Illumina HumanMethylation450 BeadChip array was used to measure DNA methylation in CpG sites. We performed a genome-wide methylation study in whole-blood DNA from 185 ischemic stroke patient cohort. Illumina HumanMethylation450 BeadChip array was used to measure DNA methylation in CpG sites.

Gene expression analysis of peripheral whole blood RNA following ischemic stroke

Project description:The purpose of this project was to elucidate gene expression in the peripheral whole blood of acute ischemic stroke patients to identify a panel of genes for the diagnosis of acute ischemic stroke. Peripheral blood samples were collected in Paxgene Blood RNA tubes from stroke patients who were >18 years of age with MRI diagnosed ischemic stroke and controls who were non-stroke neurologically healthy. The results suggest a panel of genes can be used to diagnose ischemic stroke, and provide information about the biological pathways involved in the response to acute ischemic stroke in humans. Total RNA extracted from whole blood in n=39 ischemic stroke patients compared to n=24 healthy control subjects.

Expression data from stroke patients blood samples

Project description:Ischemic stroke can be classified depending on its etiology as cardioembolic (CE), large-vessel atheroesclerotic (LAA), lacunar, other or cryptogenic. Our aim was to identify gene expression changes that could differentiate CE and LAA stroke in order to guide the optimal secondary treatment .

Identification of Blood Circular RNAs as the Potential Biomarkers for Acute Ischemic Stroke

Project description:Many hospitals lack facilities for accurate diagnosis of acute ischemic stroke (AIS). Circular RNA (circRNA) is highly expressed in the brain and is closely associated with stroke. In this study, we examined whether the blood-borne circRNAs can be promising candidates as adjunctive diagnostic biomarkers and their pathophysiological roles after stroke. We profiled the blood circRNA expression in mice subjected to experimental focal cerebral ischemia, and validated the selected circRNAs in AIS patients. We demonstrated that 128, 198 and 789 circRNAs were significantly altered at 5 min, 3 h and 24 h after ischemic stroke, respectively.

Transcriptome analysis reveals intermittent fasting-induced genetic changes in ischemic stroke

Project description:Intermittent fasting is previously reported to exhibit neuroprotection against experimental ischemic stroke. However, the detailed understanding of protection mechanisms are lacking. By observing the overall transcriptomic changes in each timepoint of ischemic stroke would benefit the understanding of underlying active pathways and mechanisms. Here, we conduct experimental MCAO ischemic stroke on mice exposed to different daily intermittent fasting method to compare not only among the ischemic stroke timepoints but also the efficacy of different intermittent fasting interventions. Our current study presented the transcriptomic changes for the first time in specific timepoints of ischemic stroke as well as under the condition of intermittent fasting. A number of neuroprotective mechanisms-related genes were significantly affected by intermittent fasting conditions in differential manners.
