| Outline of Final Research Achievements |
Life style related diseases are developed by the accumulating information related to various lifestyle habits including dietary habits. In this study, we examined whether life style related diseases are developed by the accumulating dietary habits via the novel epigenetic factor Brd4. We found that Brd4 induceｄ expression of genes related to fat synthesis/accumulation and insulin sensitivity in the liver and adipose tissues. Moreover, Brd4 activation at the healthy state induced obesity and fatty liver, whereas Brd4 repression at the obesity state induced insulin resistance. In addition, we demonstrated in this study that epigenetic biomarkers indicating Brd4 activation would predicts development of life style related diseases.
