Outline of Final Research Achievements

Postprandial hyperglycemia is transiently increased blood glucose levels that occur soon after the meal, although fasting blood glucose is normal or boundary range. Thus, it is possible that postprandial hyperglycemia cannot be detected by medical checkup that usually tested fasting blood glucose. We considered that this is one of the causes of the increased diabetic patients and analyzed the mechanism in developing postprandial hyperglycemia. As a results, the hepatic caveolin-1 was decreased and hepatic GLP-1 receptor expression was increased in the ob/ob diabetic model mice at 1 hour after a meal. These results indicated that the GLP-1 receptor dysfunction was associated with the mechanism involved in the development of postprandial hyperglycemia.
