AAV gene delivery vectors and cancer-The debate continues
(PHYSorg.com Medicine & Health)

Overwhelming evidence from the biomedical literature shows that adeno-associated virus 2 (AAV2), a viral vector often used to deliver therapeutic genes, is not associated with cancer and, in fact, may protect against cancer. Despite some previous reports insisting that AAV2 is an oncogenic virus, the preponderance of data indicates that recombinant AAV2 used in gene therapy does not integrate into the host genome increasing the risk of cancer and has anti-tumorigenic properties, as described in an article published in Human Gene Therapy.
