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.

La présente invention se rapporte à des polypeptides du récepteur 1 du facteur de croissance des fibroblastes ( FGFR1 ), du récepteur 2 du facteur de croissance des fibroblastes ( FGFR2 ), du récepteur 3 du facteur de croissance des fibroblastes ( FGFR3 ), et du récepteur 4 du facteur de croissance des fibroblastes ( FGFR4 ), et à des polynucléotides encodant les polypeptides FGFR1-4, respectivement. L'invention a également trait à des anticorps dirigés contre les polypeptides FGFR1-4 et les polynucléotides, y compris toutes leurs formes polymorphes et leurs variantes. Lesdits anticorps soit activent le polypeptide de manière spécifique soit perturbent l'activité du polypeptide de manière spécifique. L'invention concerne également des méthodes permettant de traiter des maladies, telles que des maladies prolifératives, des maladies inflammatoires et des troubles métaboliques, ainsi que des kits et des compositions faisant appel aux compositions selon l'invention. L'invention a notamment pour objet une méthode permettant de traiter des tumeurs chez un sujet, qui consiste à administrer au sujet un antagoniste de FGFR1, FGFR2, FGFR3, et/ou FGFR4.
