| Outline of Final Research Achievements |
We explored the roles of DNA methylation in AhR-dependent stress responsive pathway in intestinal mucosa. Global expression analysis was performed on RNA samples isolated from human 4 colon cancer cell lines treated withβNF (AhR ligand) and/or DAC (DNA methyltransferase inhibitor). Treatment of βNF induced 62 genes, most of which were found to be novel AhR target genes. These gene products were possible candidates for maintaining intestinal homeostasis. Induction of several genes by βNF was further enhanced by DAC, suggesting that responsiveness of AhR ligands in intestine were regulated by DNA methylation.
