Outline of Final Research Achievements |
Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn’s disease, are characterized by relapsing/remitting nature of the inflammatory process. The aim of this study was to find out key epigenetic alterations in IBD. We established the methods for epigenomic analysis for small number of isolated cells from patients with IBD. Immune cells isolated from lamina propria mononuclear cells were subjected to a chromatin immunoprecipitation (ChIP) with anti-H3K4me3, anti-H3K9me3 and anti-H3K27me3 antibodies, and ChIPed DNA was analyzed by the next generation sequencer system. Bioinformatic analysis identified the IBD-specific epigenetic dysregulation in immune cells.
