Gene therapy typically involves several steps: 1. Identification of Target Genes: Researchers first identify the specific genes that contribute to cancer. 2. Delivery Mechanisms: The therapeutic genes are delivered into the patient's cells using vectors, often viral vectors like adenoviruses or lentiviruses. 3. Gene Editing or Replacement: The introduced genes can either replace defective ones, add new genes, or employ techniques like CRISPR-Cas9 to edit faulty DNA.
