EGFR/NEDD9/TGF-β interactome and methods of use thereof for the identification of agents having efficacy in the treatment of hyperproliferative disorders
Compositions and methods for the treatment and diagnosis of cancer are disclosed.
1. A method for modulating sensitivity to EGFR/MEK-1 targeting agents in cancer cells, comprising:
a) providing cancer cells comprising genes present in an EGFR/NEDD9/TGF-β interactome, said genes being involved in cellular proliferation and EGFR/MEK-1 signalling;
b) contacting said cancer cells with at least one compound which inhibits EGFR/NEDD9/TGF-β interactome gene SC4MOL; and
c) contacting said cancer cells of step b) with at least one EGFR-MEK-1 targeting agent which is selected from erlotinib, and cetuximab, thereby increasing sensitivity to said EGFR/MEK-1 targeting agent in said cancer cells, wherein said cancer cells are squamous cell carcinoma cells.
2. The method of claim 1 , wherein said compound is a siRNA that decreases SC4MOL expression.
