Why might using retroviral vectors for gene therapy increase the patient's risk of developing cancer?

#Unit 4. Cell Communication and Cell Signaling

  1. Retroviral vectors may introduce proteins from the virus.

  2. Retroviral vectors do not express the genes that were introduced into a patient's cells.

  3. Retroviral vectors do not integrate their recombinant DNA into the patient's genome.

  4. Retroviral vectors integrate recombinant DNA into the genome in ways that may misregulate the expression of genes at or near the site of integration.
