Outline of Final Research Achievements

Type II diabetes is characterized by a progressive decline in beta-cell function and chronic insulin resistance. It is caused by the rupture of pancreatic function after long time exposure to hyperglycemia by obesity. As Japanese people genetically have low insulin secretion ability, they tend to be a type II diabetes, prevention before disease onset is important. This study aimed to show the evidence that tocotrienol (T3), a homolog of vitamin E, would be effective to prevent the onset of Type II diabetes by retention the insulin secretion ability of mice fed with a high fat diet. We clarified a part of beta cell function maintenance and its mechanism of action by vitamin E from both animal experiment and cell culture.
