The purpose of this review is to bring attention to some additional wo
rk in the tumor virus/tumor suppressor field which may have been overs
hadowed by reports describing adenovirus, SV40, and HPV oncoprotein bi
nding to pRB and p53. The data reviewed herein provide further support
for the model that a common mechanism by which DNA tumor viruses tran
sform cells involves inactivation of cellular proteins which function
as negative regulators of cell growth.
