WebJan 10, 2014 · The FGF19 gene contains several FXR-responsive elements in the second intron and promoter region [20], [26]. The IR-1 motif, which is a typical FXR-responsive element, is present in the second intron of the FGF19 gene. Ileal mRNA levels of the FXR target genes, Fgf15 and Shp, levels were increased in mice fed a high-cholesterol diet [27]. WebThe primary source of endocrine FGF19 is the ileum, where FGF19 expression is controlled by the bile acid nuclear receptor FXR (Holt et al. 2003; Inagaki et al. 2005). Bile acids released into the intestine after a meal bind to and activate FXR and thereby induce expression of FGF19.
WebFGF15/19 subsequently acts on a cell surface receptor complex in hepatocytes to repress bile acid synthesis and gluconeogenesis, and to stimulate glycogen and protein synthesis. FGF15/19 also stimulates gallbladder filling. Thus, the bile acid-FXR-FGF15/19 signaling pathway regulates diverse aspects of the postprandial enterohepatic response. WebJul 1, 2024 · Feeding responses for nutrient uptake, storage and distribution are primarily conducted by the FXR-LXR-PPARβ/δ,γ axis and supported by FGF19, while the fasting response for metabolite mobilization and break-down is centrally organized by PPARα and FGF21 [ [6], [7], [8] ]. 2.
