Outline of Final Research Achievements

Among vascular diseases, atherosclerosis is one of the most important factors of ischemic heart diseases and cerebrovascular diseases, and elucidation of the mechanism in consistent gene expression regulation of atherogenic proteins. To dissect the adhesion molecule gene regulation, we adopted a model using endothelial cells stimulated inflammatory stimulator, and presence of transcription complexes, which regulate multiple genes at the same time, was suggested. In this research, we performed (i) comprehensive chromatin interaction analysis, (ii) identification of interaction associated proteincomplex, (iii) intervention of chromatin structure, and it was observed that transcription factories regulated both induced and reduced genes from different chromosomes.
