The first human tumor virus was discovered in the middle of the last century by Anthony Epstein, Bert Achong and Yvonne Barr in African pediatric patients with Burkitt's lymphoma. To date, seven viruses -EBV, KSHV, high-risk HPV, MCPV, HBV, HCV and HTLV1- have been consistently linked to different types of human cancer, and infections are estimated to account for up to 20% of all cancer cases w...

متن کاملViruses, polymerases, and cancer.
The study of biology is partly an exercise in natural esthetics.

A virologist is among the luckiest of biologists because he can see into his chosen pet down to the details of all of its molecules. The viro...
متن کاملViruses and Human Cancer
The cause of human cancer is probably multifactorial and the role of viruses is unclear. The study of retroviruses has led to the identification of oncogenes responsible for transformation and tumor induction. Human viruses associated with malignancies include the JC virus (associated with progressive multifocal leukoencephalopathy) and some adenoviruses. No human malignancies have been associa...
