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:To determine the expression of circulating miRNAs in AIS patients with thrombolysis and without thrombolysis. Grant ID: 81100882 Grant title: The relation between transcription of miR-497 and neurons apoptosis after ischemic stroke Funding source: Chinese National Natural Science Foundation Grantee First Name: Zhen Grantee Last Name:Deng
Project description:Xuesaitong injection (XST), a standardized patent Chinese medicine of Panax notoginseng roots (Sanqi in Chinese), has long been used for effective prevention and treatment of stroke in China. However, the mechanisms underlying its effects against ischemic stroke are still poorly understood. In this study, we focused on the polypharmacology of XST against ischemic stroke with a XST-regulated stroke network analysis. Male Sprague Dawley rat model of MCAO and reperfusion were administered XST for 7 days while the control group was not treated.

In this study, we focused on the polypharmacology of XST against ischemic stroke with a XST-regulated stroke network analysis. Male Sprague Dawley rat model of MCAO and reperfusion were administered XST for 7 days while the control group was not treated. Three conditions were compared with three replicates each. These are: (1) sham; (2) model (3) XST treatment. Whole genome microarray analysis was performed using Affymetrix rat Genome 230 2.0 chips.
