Hepatic gene expression profile in persimmon peel extract administrated GK rat

ABSTRACT: Persimmon (Diospyros kaki L. f.) is a most popular fruit in Asian countries but its peels are totally wasted despite of containing a plenty of antioxidants such as carotenoids and polyphenols. We prepared a fat-soluble extract from a persimmon peel (PP) fraction and fed type 2 diabetic Goto-Kakizaki (GK) rats with a PP extract-containing AIN-93G diet (PP diet) for 12 weeks. Compared with the control AIN-93G diet, the feeding of the PP diet reduced the plasma glutamic-pyruvate transaminase activity significantly, with accumulation of M-NM-2-cryptoxanthin in the liver. A DNA microarray analysis revealed that the PP diet altered the hepatic gene expression profiles. In particular, insulin signaling pathway-related genes were significantly enriched in differentially expressed gene sets. M
