Outline of Final Research Achievements |
Human intestinal Caco-2 cells were transfected with a Pax6 promoter plasmid and effects of 376 natural compounds on the promoter activity were examined. We found that 36 compounds increased the Pax6 promoter activity. Among them, Emodin strongly increased the proglucagon meRNA level, too. Feeding emodin enhanced the glucose tolerance and intestinal proglucagon levels in the high fat loaded mice, but these mice slightly showed softer feces and intestinal inflammation. Taken together, supplemental emodin could be a novel therapeutic approach against metabolic disorders, but the side-effects should be considered in future studies.
