| Outline of Final Research Achievements |
We analyzed the interaction between ordinary food factors and anti-diabetic drug pioglitazone on the activation of PPAR gamma and the improvement of diabetes. Citrus flavonoid naringenin increased pioglitazone-induced PPAR gamma activation in vitro using a cell culture system. However, naringenin reduced the anti-diabetic effect of pioglitazone in vivo using a pathological mouse model. Naringenin did not affect serum pioglitazone concentration. In contrast, naringenin slightly affected the PPAR gamma-cofactors complex formation.
