Abstract Background During malignant progression tumor cells need to acquire novel characteristics that lead to uncontrolled growth and reduced immunogenicity. In the Bovine Leukemia Virus-induced ovine leukemia model silencing of viral gene expression has been proposed as a mechanism leading to immune evasion. However whether proviral expression in tumors is completely suppressed in vivo was not conclusively demonstrated. Therefore we studied viral expression
