An oncovirus or oncogenic virus is a virus that can cause cancer. [4] This term originated from studies of acutely transforming retroviruses in the 1950–60s, [ 5 ] when the term oncornaviruses was used to denote their RNA virus origin. [ 6 ]
An oncolytic virus is a virus that preferentially infects and kills cancer cells. As the infected cancer cells are destroyed by oncolysis , they release new infectious virus particles or virions to help destroy the remaining tumour.
The various lineages and sublineages have different oncogenic capacity, where overall, the non-European lineages are considered to increase the risk for cancer. [116] Although HPV16 is a DNA virus, there are signs of recombination among the different lineages.
Hepatitis virus-associated hepatocarcinogenesis is a serious health concern. [31] Liver cancer in the United States is primarily due to three main factors: hepatitis C virus (HCV) (22%), hepatitis B virus (HBV) (12%) and alcohol use (47%). [32] In 2017 there will be about 40,710 new cases of liver cancer in the United States. [33]
A well-known example of this is the Philadelphia chromosome, or translocation of chromosomes 9 and 22, which occurs in chronic myelogenous leukemia and results in production of the BCR-abl fusion protein, an oncogenic tyrosine kinase.
The Epstein–Barr virus (EBV) is one of the nine known human herpesvirus types in the herpes family, and is one of the most common viruses in humans. EBV is a double-stranded DNA virus and is also called human herpesvirus 4 (HHV-4). [2] Epstein–Barr virus (EBV) is the first identified oncogenic virus, or a virus that can cause cancer. EBV ...
