Oncornaviruses
WebAn immunologic test-system for an oncornavirus of Type B isolated from an HEp2 cell line was obtained. The virus-specific serum detects both extracellular and intracellular antigens of the virus as well as antigens of oncornaviruses of Type B revealed in HeLa, DAPT, RH, Detroit 6, and A1 cell lines.

An oncovirus or oncogenic virus is a virus that can cause cancer. This term originated from studies of acutely transforming retroviruses in the 1950–60s, when the term "oncornaviruses" was used to denote their RNA virus origin. With the letters "RNA" removed, it now refers to any virus with a DNA or … Pogledajte više Generally, tumor viruses cause little or no disease after infection in their hosts, or cause non-neoplastic diseases such as acute hepatitis for hepatitis B virus or mononucleosis for Epstein–Barr virus. A minority of … Pogledajte više In the 1960s, the replication process of RNA virus was believed to be similar to other single-stranded RNA. Single-stranded RNA replication involves RNA-dependent RNA synthesis which meant that virus-coding enzymes would make partial double … Pogledajte više The main viruses associated with human cancers are the human papillomavirus, the hepatitis B and hepatitis C viruses, the Epstein–Barr virus, the human T-lymphotropic virus Pogledajte više The history of cancer virus discovery is intertwined with the History of cancer research and the history of virology. The oldest surviving record of a human cancer is the Pogledajte više A direct oncogenic viral mechanism involves either insertion of additional viral oncogenic genes into the host cell or to enhance already existing oncogenic genes ( Pogledajte više DNA oncoviruses typically impair two families of tumor suppressor proteins: tumor proteins p53 and the retinoblastoma proteins (Rb). It is evolutionarily advantageous for viruses to inactivate p53 because p53 can trigger cell cycle arrest or apoptosis … Pogledajte više DNA viruses • Human papillomavirus (HPV), a DNA virus, causes transformation in cells through interfering with tumor suppressor proteins such as p53.
