L. Corbo et al., THE EBV EARLY GENE-PRODUCT EB2 TRANSFORMS RODENT CELLS THROUGH A SIGNALING PATHWAY INVOLVING C-MYC, Oncogene, 9(11), 1994, pp. 3299-3304
Epstein-Barr virus (EBV) is a ubiquitous human herpesvirus associated
with several neoplasia. We present evidence here that the protein EB2,
an EBV posttranscriptional activator, has transforming properties not
only when expressed in established cell lines such as Rat1 or NIH3T3
but also in primary rat fibroblasts (REF). EB2 transformation in Rat1
cells correlates with an increase in the steady-state level of the cel
lular oncogenic protein c-Myc, and cotransfection of a plasmid express
ing Max suppresses the transformation. These results implicate c-Myc i
n EB2-mediated cell transformation and help define the pathway by whic
h this EBV early protein causes transformation.
