FIBROBLAST GROWTH FACTOR RECEPTORS 1, 2, 3, AND 4 AS TARGETS FOR THERAPEUTIC INTERVENTION

摘要

Isolated fibroblast growth factor receptor 1 (“FGFR1”), fibroblast growth factor receptor 2 (“FGFR2”), fibroblast growth factor receptor 3 (“FGFR3”), and fibroblast growth receptor 4 (“FGFR4”) polypeptides and polynucleotides encoding the FGFR1-4 polypeptides, respectively, are provided. Additionally, antibodies, directed to the FGFR1-4 polypeptides and polynucleotides, inclusive of all polymorphic forms and variants thereof, are described. These antibodies either specifically activate the polypeptide or specifically interfere with the activity of the polypeptide. Further provided are methods of treating diseases, such as proliferative diseases, inflammatory diseases, and metabolic disorders, and kits and compositions employing the disclosed compositions. Specifically disclosed is a method of treating tumors in a subject where an antagonist of FGFR1, FGFR2, FGFR3, and/or FGFR4 is administered to the subject.
