Abstract

Cervical and other anogenital malignancies are largely caused by E6 and E7 oncogenes of high-risk human papillomaviruses (HPVs), which inhibit important tumor suppressors like p53 and pRb when they are persistently activated. The main goal of traditional treatments is to physically or chemically kill cancer cells, but they frequently only offer temporary relief, have serious side effects, and have a high risk of recurrence. Exploring the efficacy and accuracy of CRISPR-Cas9 gene editing in both inducing death in HPV-infected cancer cells and restoring the activity of tumor suppressors is our main goal. In this study, we propose a novel precision oncology strategy that targets and inhibits the detrimental effects of the E6 and E7 oncogenes using the CRISPR-Cas9 gene editing system. In order to do this, we create unique guide RNAs that target the integrated HPV DNA and reactivate p53 and pRb. Reactivation is meant to halt aberrant cell development and restart the cell’s natural dying pathways. This review discusses the potential of CRISPR/Cas9 in targeting HPV oncogenes, with a focus on studies that have demonstrated its promise in cancer treatment. Given the absence of a definitive treatment for papillomavirus infection and its subsequent association with various cancers, future clinical trials and experimental investigations appear essential to establish and evaluate the therapeutic potential of CRISPR-based approaches. This approach provides a less invasive alternative to conventional treatments and opens the door to personalized care that considers the genetic makeup of each patient’s tumor. © 2025 Elsevier B.V., All rights reserved.
