FGF-19 is a member of the fibroblast growth factor （FGF） family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes including embryonic development cell growth, morphogenesis, tissue repair, tumor growth and invasion. This growth factor is a high affinity, heparin dependent ligand for FGFR4. FGF19 has important roles as a hormone produced in the ileum in response to bile acid absorption. Bile acids bind to the farnesoid X receptor （FXR）, stimulating FGF19 transcription. FGF19 regulates new bile acid synthesis, acting through the FGFR4/Klotho-β receptor complexes in the liver to inhibit CYP7A1. FGF19 also has metabolic effects, affecting glucose and lipid metabolism when used in experimental mouse models. Furthermore, FGF19 is frequently amplified in human cancers. Amplification of the FGF19 genomic locus was found in liver cancer, breast cancer, lung cancer, prostate cancer, bladder cancer, and esophageal cancer, among others. Targeting FGF19 inhibits tumor growth in colon cancer cells and hepatocellar carcinoma. Increase in FGF19 correlates with tumor progression and poorer prognosis of hepatocellular carcinoma.
