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.

Project description:The high incidence, mortality, and disability rate of ischemic stroke impose huge economic burdens on patients and social health care systems.N6-methyladenosine (m6A) is one of the most extensive RNA methylation modifications in eukaryotes and participates in the pathogenesis of numerous diseases including ischemic stroke. Peripheral blood neutrophils are forerunners after ischemic brain injury and exert crucial functions.However, the underlying mechanisms of neutrophils in ischemic stroke need to be further clarified. This study aims to explore the transcriptional profiles of m6A modification in neutrophils of patients with ischemic stroke. The Arraystar Human m6A-mRNA&lncRNA Epitranscriptomic microarray analysis was performed on the peripheral blood neutrophils of 3 patients with ischemic stroke and 3 healthy controls, providing the clinical significance of m6A modification on ischemic stroke.

Project description:Elevated plasma homocysteine is an independent risk factor for cardiovascular disease and stroke, however the etiology remains poorly understood. Elevated homocysteine is known to inhibit methyltransferases including DNA methyltransferases, but no methylome-wide analysis of elevated homocysteine has been reported. Peripheral blood genomic DNA methylation in 8 Singaporean-Chinese ischemic stroke patients (4 male, 4 female) with varying homocysteine titer and hypertensive status were profiled using methyl-CpG binding domain (MBD) protein-enriched genome sequencing (MBD-seq) on Illumina Genome Analyzer IIx. A methylome wide screen was undertaken for gender, total plasma homocysteine, hypertension and age. The data show considerable variability within the small cohort, including at genes which are related to one carbon metabolism and cardiovascular disease. Peripheral blood genomic DNA methylation in 8 Singaporean-Chinese ischemic stroke patients (4 male, 4 female) was profiled using methyl-CpG binding domain (MBD) protein-enriched genome sequencing (MBD-seq) on Illumina Genome Analyzer IIx. Methylation parrterns were correlated with homocysteine levels, lypertensive status, gender and age.

Project description:Elderly patients suffer more brain damage in comparison with young patients from the same ischemic stroke. In that regard, it is imperative to investigate the factors responsible for decreased resistance to anti-ischemic/hypoxic injury in the aged brain. We conducted analysis of the gene expression pattern on our samples (Transient MCAO for 60 minutes established acute ischemic stroke followed by 3 days reperfusion) by the Affymetrix rat 230 2.0 chip.

Project description:The roles of mRNA and microRNA (miRNA) are widely known in many diseases including acute ischemic stroke. About 60 % of all human messenger RNAs (mRNAs) are regulated by microRNAs. Integration analysis using mRNA and miRNA are important to elucidate pathogenesis. But the contribution of mRNA and miRNA, especially miRNA targeted mRNA, related with severity of acute ischemic stroke is not remain understood. To clarify the pathway related with the severity of acute ischemic stroke, we examined mRNA and miRNA integration analysis targeted for acute ischemic stroke.

Project description:Obesity is well recognized as a risk factor for coronary heart disease and mortality. The relationship between abdominal obesity and ischemic stroke remains less clear. Previous publication showed the obesity is an independent, potent risk factor for ischemic stroke in all race-ethnic groups. It is a stronger risk factor than BMI and has a greater effect among younger persons. The goal of this experiment was to compare genome wide enrichment of H3K9ac histone mark profile of white blood cells of healthy controls, patients with obesity and/or stroke in order to understand the histone modifications differences behind the different phenotypes. There were 3 subjects in each group.
