| Outline of Final Research Achievements |
The relationship between the pathology of various diseases and the DNA damage repair system has been clarified. The contribution of cardiovascular risk factors such as diabetes, hypertension, smoking, dyslipidemia, and aging to disease onset depends on the difference in response of individual's cells. We investigated whether the amount of DNA double strand breaks (DSBs) in the mononuclear cells may be an inclusive biomarker for the risks. We found that the amount of DSBs in the mononuclear cell correlates with a specific risk factor rather than the presence of arteriosclerosis. This is important in contributing to the stratification of risk, and we will continue to study the mechanism while increasing the number of cases.
