| Outline of Final Research Achievements |
Using serum stored from the JACC Study, we measured levels of miRNA (miR-21, miR-29a and miR-216), Vitamin E, retinol and high-sensitivity C-reactive protein (hs-CRP) and compared 336 cases of death before 65 years old with 926 sub-cohort members randomly selected from those aged 40-64 years at baseline. Compared with those in the highest quartile, those whose miR-29a and hsCRP levels were in the lowest quartile had a significantly lower risk of premature death. A similar tendency was also found for miR-126 levels. However, it was not statistically significant. Other biomarkers shoed no meaningful associations. We will interpret the results carefully to ascertain the significance of these biomarkers.
