Outline of Final Research Achievements

The aim of this study was to analyse the characteristic metabolites of the diabetes onset in the dog and compare the difference between the hyperadrenocorticism (HAC) of the dog which reported in that diabetes develops following insulin resistance and the obesity of the dog.
In canine myotube-like cell which added dexamethasone, glucose uptake ability was inhibited, and a catabolic reaction of the glucose tended to decrease.On the other hand, with canine myotube-like cells which added TNF-α, β-amino-isobutyric acid reinforcing insulin sensitivity significantly increase, and it is thought that it is action to compensate insulin resistance. Difference of these metabolites between HAC and obesity shows the cause that the HAC of the dogs leads to the diabetes onset, and the cause that the obesity of the dogs does not lead to diabetes. Thus, these results may be useful for further study of the diabetes onset mechanism in dogs.
