A patient experiencing a disease state due to a gene deletion was treated with adenovirus gene therapy. The gene therapy was successful and the gene deletion was corrected. However, the patient began to develop cancer not long after the gene therapy
Develop a theory as to why the cancer presented so rapidly after gene therapy.
What will be an ideal response?
The cancer is most likely a direct result of the gene therapy. The use of adenovirus as a gene therapy vector results in the therapeutic gene inserting at random into the host cell genome. In this case, the therapeutic gene most likely inserted into the host genome in such a way as to be tumorigenic.
