| Research Abstract |
We studied on the bile acid-mediated regulation of ileal FGF15/19 expression and FGF15/19-mediated regulation of hepatic lipid metabolism. The suppression of enterobacteria-mediated bile acid conversion decreased ileal FGF15 levels resulting in the elevation of hepatic bile acid synthesis. Multiple FXR responsive elements that are involved in the bile acid-mediated transcriptional activation of FGF19 gene we re found in the promoter region. FGF19 treatment decreased hepatic triglyceride and free fatty acid levels in Fxr-null mice.
