Abstract

Quail embryo fibroblasts infected with any of the four natural avian myc gene-containing virus strains (MC29, CMII, OK10 and MH2) or with the myb, ets-containing E26 acute leukemia virus, were examined for their expression of several transformation-associated parameters. All myc-containing viruses, but not E26 or Rous sarcoma virus (used as a control) induced a dramatic stimulation of cell proliferation. In addition, the myc virus-transformed cells exhibited prominent nucleoli, possibly as a consequence of their increased proliferation. Cells transformed by MC29, OK10, MH2 and E26 were capable of growing in semi-solid medium and showed a loss of actin cables and, in most cases, of an ordered fibronectin distribution. All of the myc virus-transformed fibroblasts, as well as the E26-transformed cells, were unable to form tumors in nude mice, indicating that the myc gene (and the myb/ets genes) are not sufficient for the induction of a fully malignant phenotype in avian fibroblasts.
