Outline of Final Research Achievements |
The present study demonstrated for the first time in mouse experiments that excess intake of fatty foods augments ER stress in hypothalamus, which in turn increases the preference for dietary fats, thereby making a self-adjusting circuit. Gamma-oryzanol is a unique bioactive substance exclusively and abundantly found in brown rice. We found that γ-oryzanol decreases ER stress in hypothalamus and attenuates the preference for dietary fat, thereby ameliorating high fat diet (HFD)-induced fuel dyshomeostasis. We also tested whether γ-oryzanol reduces ER stress and improves function and survival of pancreatic β-cells under high fat diet in mice. In pancreatic islets from HFD-fed diabetic mice, oral administration of γ-oryzanol improved glucose stimulated insulin secretion (GSIS) on following reduction of exaggerated ER stress and apoptosis. A line of novel findings may open a fresh avenue for natural food-based approach toward the prevention of obesity-diabetes syndrome.
