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 ]
Herpesviruses also cause cancer in animals, especially leukemias and lymphomas. [13] Human T cell lymphotropic virus was the first human retrovirus discovered by Robert Gallo and colleagues at NIH. [20] The virus causes Adult T-cell leukemia, a disease first described by Takatsuki and colleagues in Japan [21] and other neurological diseases ...
The herpes simplex virus type 1 (HSV-1) mutant 1716 lacks both copies of the ICP34.5 gene, and as a result is no longer able to replicate in terminally differentiated and non-dividing cells but will infect and cause lysis very efficiently in cancer cells, and this has proved to be an effective tumour-targeting strategy.
The herpesviruses, Kaposi's sarcoma-associated herpesvirus and Epstein-Barr virus, are believed to cause cancer in humans, such as Kaposi's sarcoma, Burkitt's lymphoma, and nasopharyngeal carcinoma. Although genes have been identified in these viruses that cause transformation, the manner in which the virus transforms and replicates the host ...
A number of viruses named oncoviruses cause cancer. These are mainly human papilloma virus causing cervical carcinoma, and Epstein-Barr virus causing B cell lymphomas and nasopharyngeal carcinomas. Kaposi sarcoma virus and Merkel cell polyoma virus cause skin cancers. Human T-lymphotropic virus (HTLV) causes T cell leukemias.
Retroviruses that cause tumor growth include Rous sarcoma virus and mouse mammary tumor virus. Cancer can be triggered by proto-oncogenes that were mistakenly incorporated into proviral DNA or by the disruption of cellular proto-oncogenes. Rous sarcoma virus contains the src gene that triggers tumor formation. Later it was found that a similar ...
New tests done by the Environmental Working Group have found 21 oat-based cereals and snack bars popular amongst children to have "troubling levels of glyphosate." The chemical, which is the ...
Viruses [66] are the usual infectious agents that cause cancer but bacteria and parasites may also play a role. Oncoviruses (viruses that can cause human cancer) include: Human papillomavirus (cervical cancer), Epstein–Barr virus (B-cell lymphoproliferative disease and nasopharyngeal carcinoma),
