Background: Fibroblast growth factor receptor (FGF-R) family consists of four genes encoding closely related transmembrane, tyrosine kinase receptors (termed FGF-R1 toFGF-R4). FGF bind in the presence of heparan sulfate proteoglucans (HSPG) to FGF-R forming a dimeric 2:2:2 FGF-FGFR-HSPG ternary complex forms on the cell surface. Complex formation induces receptor dimerization and a subsequent transphosphorylation of tyrosine residues in the activation loop of the kinase domain. Receptor activation regulates many key processes such as cell proliferation, survival, migration and differentiation by linking FGF-R to RAS / MAPK and PI3K / AKT and PKC pathways. Aberrant expression and polymorphism of fibroblast growth factor receptor 4 (FGFR4) has been linked to tumor progression and anticancer drug resistance.
