Matrix-independent activation of phosphatidylinositol 3-kinase, Stat3, and cyclin A-associated Cdk2 Is essential for anchorage-independent growth of v-Ros-transformed chicken embryo fibroblasts.

Abstract excerpt

The question remains open whether the signaling pathways shown to be important for growth and transformation in adherent cultures proceed similarly and play similar roles for cells grown under anchorage-independent conditions. Chicken embryo fibroblasts (CEF) infected with the avian sarcoma virus UR2, encoding the oncogenic receptor protein-tyrosine kinase (RPTK) v-Ros, or with two of its transformation-impaired...
