Outline of Final Research Achievements

Dysregulation of glucagon is associated with the pathophysiology of type 2 diabetes. We previously reported that postprandial hyperglucagonemia is more obvious than fasting hyperglucagonemia in type 2 diabetes patients. Among them, postprandial hypersecretion of glucagon in the diabetic state is attributable to disordered BCAA catabolism in pancreatic islet cells. Therefore, we generated mice deficient in pancreatic α-cell-specific BCAA metabolism-related enzymes (Glucagon Cre, BDK floxed mice were crossed: αBDK-KO mice) and evaluated their glucagon secretory ability.

Academic Significance and Societal Importance of the Research Achievements

糖尿病病態では、インスリンの分泌障害に着目されがちな中、グルカゴンの分泌障害も病態に強く影響を及ぼしている。本研究ではグルカゴンの分泌障害機序を代謝の観点から解明し、食事療法および薬物療法双方への応用が期待できる。
