Genetic engineering in oncology based on CRISPR-CAS9 technology

Purpose of the study: analysis of modern scientific data on the molecular mechanisms of the CRISPR-Cas9 system in gene editing, advantages and disadvantages in cancer research and the development of new treatment methods. Material and Methods. A comprehensive electronic search of relevant published studies was conducted in the scientific databases PubMed/MEDLINE, ScienceDirect, Wiley and Google Scholar published between 2014 and 2024. The search was tailored to the specific requirements of each database based on the following keywords: CRISPR-Cas9, sgRNA, genome editing, cancer immunotherapy, CAR-T. The search yielded 487 studies on the topic of interest, of which 54 were used to write the literature review. Additionally, the article discretely highlights the importance and challenges of CRISPR-Cas9 in the production of genetically engineered T cells for potential use in treating certain types of cancer.
