Outline of Final Research Achievements

Mitochondria are highly dynamic organelles that frequently fuse and divide in response to cellular energy demands. In an excessive energy state such as a high fat diet, the organelle network between Mt and ER is impaired, followed by the induction of ER stress. As a result, FGF21 is secreted from the liver by activation of PERK-eIF2a-ATF4 pathway, and energy expenditure is accelerated in the peripheral organs such as skeletal muscle and adipose tissue. In other words, mitochondrial dynamics-ER stress-FGF21 axis function as a biological defense system for energy excess. Therefore, mitochondrial dynamics is a therapeutic target for the obese diabetes.
