| Outline of Final Research Achievements |
In this study, we found that expressions of genes related to nutrient digestion and absorption, and their transcriptional factors in the small intestine were reduced by the fasting in rats and african clawed frogs. There expressions were rapidly recovered in the african clawed frogs, but less in rats, by the re-feeding. Histone modifications such as acetylations in these genes were enhanced in african clawed frogs, but not in rats, by the re-feeding. Food factors inducing the histone acetylation such as short-chain fatty acids and medium-chain fatty acids has the potency of enhancing genes related to nutrient digestion and absorption in human intestine-like culture cells.
