Abstract

We have isolated two recessive, mutually complementary NRK cell mutants that are refractory to transformation by epidermal growth factor (EGF) and transforming growth factor-beta. Both mutants are defective in a signal transduction cascade shared by EGF and platelet-derived growth factor (PDGF). Analysis of the mutants suggests that transformation of NRK cells by the v-fms, v-erbB, activated erbB-2, v-ras, v-fos, v-mos, v-fes, v-src, SV40 large T, polyomavirus middle T, and human papillomavirus type 16 E6,E7 oncogenes is mediated by the EGF/PDGF signal cascade. The data also suggest that the EGF/PDGF cascade branches into mitogenic and oncogenic signals, the latter of which is required for soft agar growth and focus formation.
