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 ]
Despite the promises of early in vivo lab work, these viruses do not specifically infect cancer cells, but they still kill cancer cells preferentially. [38] While overall survival rates are not known, short-term response rates are approximately doubled for H101 plus chemotherapy when compared to chemotherapy alone. [ 38 ]
In other cases, the virus can cause systemic disease through a disseminated infection spread throughout the body. The predominant mode of viral dissemination occurs through the blood or lymphatic system , some of which include viruses responsible for chickenpox ( varicella zoster virus ), smallpox ( variola ), HIV ( human immunodeficiency virus ).
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 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 carcinogen (/ k ɑːr ˈ s ɪ n ə dʒ ən /) is any agent that promotes the development of cancer. [1] Carcinogens can include synthetic chemicals, naturally occurring substances, physical agents such as ionizing and non-ionizing radiation, and biologic agents such as viruses and bacteria. [2]
Further research done later on by others showed that RSV was a type of retrovirus.It was found that the v-Src gene in RSV is required for the formation of cancer. [3]A function for Src tyrosine kinases in normal cell growth was first demonstrated with the binding of family member p56lck to the cytoplasmic tail of the CD4 and CD8 co-receptors on T-cells. [4]
Cancer virus refers to: An oncovirus, a virus that can cause cancer. Also generally the role of viruses in carcinogenesis. On the other hand to an oncolytic virus, ...
