Evaluation of: Stevenson PG, May JS, Connor V, Efstathiou S: Vaccination against a hit-and-run viral cancer. J. Gen. Virol. 91, 2176-2185 (2010). Viral hit-and-run oncogenesis scenarios suggest that transient acquisition of viral genomes can induce a permanent change in the gene expression pattern of the host cell, resulting in malignant conversion. Stevenson et al. developed an in vivo model system based on the introduction of a Cre-recombinase positive murid herpesvirus into genetically engineered mice. They demonstrated that the Ore recombinase could switch on a silent oncogene and inactivate a tumor suppressor gene resulting in sarcomagenesis. However, some of the tumors lacked herpesvirus genomes, suggesting a hit-and-run type oncogenesis. The authors also observed that vaccination could prevent sarcomagenesis in their model.
