Outline of Final Research Achievements

Higher order structures in the cell nucleus have been demonstrated to change during development and differentiation. Such structural remodeling occurred in the cell nucleus can be observed as changes in high electron density areas called chromatin by electron microscopy. Alterations in nuclear chromatin structure have been reported some relation with physiological changes. Based on our experimental findings of chromatin remodeling as an upstream of pathological gene expression in cardiomyocytes, we focused on changes in nuclear chromatin structure of cardiomyocytes in patients with dilated cardiomyopathy (DCM). Using our original quantitation methods to analyze the ultrastructure of chromatin, we conducted a retrospective observational study assessing the ability to identify the DCM patients with severe heart failure at risk for poor outcomes, and to make an accurate and an early determination of the indication for some ventricular assist devices to support the failing heart.
