| Outline of Final Research Achievements |
Novel mechanism of food effect on human intestinal function was studied by focusing on microRNA included in food abundantly. By in vitro experiments, apple derived-nanoparticle (APNP) decreased mRNA and protein expression of intestinal transporters. 3’-UTR of transporter gene interacted with APNP. Furthermore, APNP included variable apple-derived microRNA, involvement of microRNA in this down regulation was suggested. Data-base analysis demonstrated that apple microRNA interact with the specific transporter gene. The suggested microRNA downregulated expression of the transporter gene and protein. Accordingly, since microRNA is a large molecule, it was clearly shown that food-derived large molecules such as microRNA directly affect intestinal function through nanoparticle of food, The conclusion also provides new concept of nutrients that food-derived large molecules are directly functional to affect human health.
