Ligand-Independent EGFR Signaling.

Abstract excerpt

Constitutive activation of the EGFR is common in cancer due to EGFR wild-type (EGFRwt) overexpression or the presence of mutant EGFR. Signaling by constitutively active NSCLC EGFR mutants or the EGFRvIII mutant in glioblastoma has been studied intensively and the downstream signals are known. Normally, the EGFRwt is activated when it is exposed to ligand, resulting in activation of canonical signals such as ERK...
