Abstract
The invention provides materials, reagents, systems, and methods for identifying agents useful for treating diseases resulting from abnormal (e.g., excessive) FGF receptor signaling. The invention also provides (therapeutic) agents thus identified, and methods of using such agents in treating such diseases. In certain embodiments, the invention relates to the treatment of various craniofacial disorders, or Craniosynostosis, that result from FGFR (e.g. FGFR2) malfunction, such as Crouzon, Apert, Jackson-Weiss, Pfeiffer Syndromes, Crouzon+acanthosis nigricans, Beare-Stevenson cutis gyrata, and non-syndromic craniosynostosis (NS). The methods comprise administering to the individuals a therapeutically effective amount of an inhibitor of the FGFR2c-FRS2 signaling. The inhibitor inhibits signaling by antagonizing FGFR2c-FRS2 interaction, inhibiting the expression and/or subcellular localization of wild-type or mutant FGFR2c and/or FRS2, inhibiting the kinase activity of FGFR2c (e.g. for autophosphorylation and/or phosphorylation of FRS2), and/or inhibiting downstream signaling of FRS2 (such as Sos-Ras-MAPK, Shp2, and/or Gab 1-PI3K pathways).
