Outline of Final Research Achievements |
We investigated whether osteocalcin (OC) and undercarboxylated osteocalcin (ucOC), which are hormones that regulate glucose metabolism in animals, increase the risk of diabetes, metabolic syndrome (MS), and arteriosclerosis in humans. In 1316 women who participated in the JPOS cohort study, excluding those who had these outcomes at baseline, new onsets were captured during the following 10 years. As a result, there was no significant association with OC, and the lowest quartile of ucOC tended to have a higher risk of developing diabetes, and a significantly higher risk of developing MS. It was suggested that ucOC may regulate glucose metabolism and is involved in the development of MS also in humans.

Academic Significance and Societal Importance of the Research Achievements |
本申請課題により、低ucOCがインスリンを介して、血糖値を上げ、アディポネクチンを介してインスリン抵抗性を増強し、もって糖尿病とメタボリック症候群のリスク、動脈硬化進展の度合いを高めるという仮説が証明されれば、ucOCがある値より低ければ、2型糖尿病やメタボリック症候群の発生や動脈硬化が進展するリスクが高いことがわかり、ハイリスク者に重点的な発症予防策を講じることによりこれらの疾患、ひいては循環器疾患の発生を効率的に予防することが可能になる。健康寿命延伸を阻む課題となっている糖尿病や動脈硬化性疾患の発症前発見と対策に道を開くことができる。
