http://purl.uniprot.org/citations/24893630 | http://www.w3.org/2000/01/rdf-schema#comment | "PurposeEGF-stimulated signaling via EGF receptor (EGFR) is important in colorectal tumorigenesis and drug targeting. However, anti-EGFR therapy is not effective in a subset of patients with colorectal cancer, suggesting that unidentified EGF-stimulated pathways might play roles in colorectal cancer. Previously, we identified KAI1 C-terminal interacting tetraspanin (KITENIN) as a metastasis-enhancing gene and found it to be highly expressed in sporadic colorectal cancer tissues. We recently found that EGF further increases KITENIN-induced elevated AP-1 activity. Here we attempted to clarify this novel EGF-stimulated molecular pathway and its roles in colorectal cancer.Experimental designWe analyzed how EGF modulates the downstream signaling pathway of oncogenic KITENIN in colorectal cancer cells. Biological alterations following EGF treatment were identified in KITENIN-overexpressed colorectal cancer cells with or without alteration of EGFR activity.ResultsWe identified the KITENIN/ErbB4-Dvl2-c-Jun axis as a novel downstream signal of EGF that is switched on under elevated KITENIN conditions in an EGFR-independent manner. This unconventional EGF signal upregulates c-Jun and enhances invasion and anchorage-independent growth of colorectal cancer cells. In addition, tumor tissues from metastatic patients with colorectal cancer who showed initial poor responses to cetuximab/chemotherapy expressed higher levels of KITENIN than did responders to therapy.ConclusionsOur results highlight the role of an EGFR-independent EGF signal in mediating the invasiveness and tumorigenesis of colorectal cancer cells. This unconventional pathway might be related to the limited clinical efficacy of anti-EGFR agents in a subset of patients with colorectal cancer."xsd:string |
