D-298 MG amplifies a rearranged epidermal growth factor receptor (EGFR) gene (
c-erbB proto-oncogene
), resulting in an in-frame deletion of 83 amino acids in domain IV of the extracellular domain of the EGFR. EGF and transforming growth factor-a (TGF-a) bound to the mutant EGFR with high affinity and enhanced the intrinsic mutant EGFR kinase activity. The mutant EGFR was capable of transducing EGF-stimulated

cell proliferation and invasiveness in an in vitro three-dimensional spheroid model. The deletion-mutant EGFR in D-298 MG is capable of being activated by growth factor; this suggests that overexpression of this mutant EGFR protein rather than structural alteration may be the more significant biologic event.
