Host DNA Replication Is Induced by Geminivirus
... Mammalian DNA tumor viruses establish permissive conditions for DNA replication by inactivating tumor suppressor proteins, such as pRb and p53, and upregulating DNA replication-associated proteins, such as PCNA (Nevins, 1992; Jansen-Durr, 1996). TGMV may use a similar strategy because the TGMV AL1 p ...
