| Outline of Final Research Achievements |
Cardiac macrophages play various roles in the cardiac response to stress. In this study we hypothesized that the changes in cardiac macrophage function might contribute to the development of heart failure and that the changes might be regulated by the interaction between cardiac microenvironment and macrophages. We analyzed transcriptomes and epigenome in macrophages by RNA-seq and ATAC-seq and found that cardiac stress greatly altered epigenome in macrophages. We then identified several transcriptional regulatory motifs that may control epigenome in response to cardiac stress. We have also identified regulatory regions that respond to cardiac microenvironment and regulate cardiac macrophage-specific gene expression.
