Ligand activation of overexpressed epidermal growth factor receptors transforms NIH 3T3 mouse fibroblasts.

By H Riedel, S Massoglia, J Schlessinger and A Ullrich


The cell surface receptor for the mitogenic peptide epidermal growth factor (EGF) is involved in control of normal cell growth and may play a role in the genesis of human neoplasia such as squamous carcinoma and glioblastoma. Soft-agar growth and focus-formation experiments with NIH 3T3 mouse fibroblasts transfected with an expression plasmid demonstrated the ligand-dependent transforming potential of the human EGF receptor without structural alterations. Activation of overexpressed normal receptor alone appears to be sufficient for transformation of NIH 3T3 cells in vitro
