Oncovirus
An oncovirus is a cancer cause virus and often called oncornaviruses due to their RNA virus origin. Oncoviruses can control cell cycle mechanisms of Retinoblastoma protein. Some viruses are tumorigenic when they infect a cell and persist as circular episomes or plasmids, replicating separately from host cell DNA. Other viruses are only carcinogenic when they integrate into the host cell genome as part of a biological accident, such as polyomaviruses and papillomaviruses. Viruses with a DNA genome, such as adenovirus, and viruses with an RNA genome, like the Hepatitis C virus, can cause cancers, as can retroviruses having both DNA and RNA genomes. In many cases, tumor viruses do not cause cancer in their native hosts but only in dead-end species. Eg, adenoviruses do not cause cancer in humans they only become tumorigenic when infected into certain rodent species, such as Syrian hamsters.
