Outline of Final Research Achievements

Pancreatic islets were isolated from diabetes-prone (Prone) and diabetes-resistant (Resistant) mice, and used for each analysis. There are heritable differences in insulin secretion capacity between the two lines of mice. Many differences were observed in gene expression of molecules involved in metabolism and transport of fatty acids and lipids. We found that different expression levels of CD36, known as a fatty acid transporter on plasma membrane, in pancreatic beta cells may determine the heritable differences in insulin secretion capacity.

Academic Significance and Societal Importance of the Research Achievements

Prone系とResistant系の両系統マウスは、多遺伝子性の遺伝的要因と環境的要因との相互作用というヒトにおける2型糖尿病発症基盤を正しく反映して作出されたモデル動物である。両系統間での遺伝的なインスリン分泌能の差異について、その出現機序の解明を目的とした本研究の成果は、ヒトにおける2型糖尿病の発症基盤や発症における個人差の成因解明、さらには、それらに基づいた糖尿病予防・治療法開発に繋がる基礎的知見となるものと考えられる。
