Popis: Epigenetic modification, particularly changes in DNA methylation at gene promoters, is implicated in the pathogenesis of atherosclerosis. However, the analysis of DNA methylation in atherosclerosis has been limited to a few selected candidate genes. In this study, we therefore performed a genome-wide analysis of DNA methylation in the atherosclerotic human aorta. A total of 48 post-mortem human aortic intima specimens were examined. To avoid the effects of interindividual variation, we performed intraindividual paired comparisons between atheromatous plaque lesions and corresponding plaque-free tissue for 24 subjects. Bisulfite-modified genomic DNA was analyzed for DNA methylation with a specific microarray (Illumina HumanMethylation450 BeadChip). We compensated for multiple comparisons by applying Bonferroni's correction for statistical significance of association. DNA methylation was significantly (P
