| Outline of Final Research Achievements |
We evaluated a novel molecular mechanism targeted PPAR activation, protecting lifestyle-related diseases by the food-derived components such as resveratrol. 4-week intake of resveratrol reduced plasma triglycerides, and upregulated the hepatic expression of PPARα-responsive genes in the wild-type (WT), but not in PPARα-knockout (KO) mice, and that, long-term intake of resveratrol in combination with a high-fat diet prevented the accumulation of lipids in both the white adipose tissue and the liver, improving life span. Moreover, habitual exercise with a intake of resveratrol induced the muscular expression of PPARα-responsive genes in WT, but not in KO mice and improved endurance capacity. We also found that 4’-hydroxyl group of resveratrol is critical for the direct activation of PPARα. Furthermore, a pungent component derived from plants and a major component of cinnamon bark oil activated PPAR and suppressed COX-2 expression.
