| Outline of Final Research Achievements |
To improve the health condition of elderly people, Nose et al. have developed an exercise program termed high-intensity interval walking training (IWT). Conventional physical and biochemical markers have shown the health-promoting effects of IWT. On one hand, we have been also investigating the effects of IWT from molecular-biological points of view.
In this study, we did epigenetical investigation on the effects of IWT with genome-wide DNA methylation assays. Our aim was to uncover genes that respond to IWT through examining DNA methylation changes in samples of IWT subjects. The obtained results indicated that IWT led to epigenetically suppress a pro-inflammatory status, consistently with our previous study on pro-inflammatory ASC gene methylation. We found significant methylation changes in several genes relating to inflammation. In particular, it was note-worthy that NFkB2, one of master genes for inflammation, was hyper-methylated.
