The synergistic effect of DNA nanostructures and CRISPR/Cas system for cancer diagnosis and treatment.

Cancer remains one of the most formidable global public health challenges, exerting a profound and detrimental impact on human health. Despite substantial advancements in cancer research, the escalating incidence and mortality rates underscore the persistent and growing burden on global healthcare systems. The Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas system, heralded as a revolutionary gene-editing tool, holds immense promise for cancer treatment. However, its efficacy is critically contingent upon developing efficient delivery strategies. DNA nanocarriers, characterized by their programmability, sequence specificity, and design flexibility, emerge as a highly effective vehicle for delivering the CRISPR/Cas system, facilitating the precise transportation of gene-editing tools to the cell nucleus. The integration of DNA nanocarriers with CRISPR/Cas technology provides a new paradigm for precise and controllable gene editing. Through programmable spatial assembly, DNA nanocarriers can protect Cas9 ribonucleoprotein complexs (RNPs), facilitate endosomal escape, and co-localize donor DNA to promote homology-directed repair. These synergistic effects bridge molecular programmability and genetic functionality, paving the way for safer and more efficient genome engineering. This review aims to evaluate the application of DNA nanocarriers in cancer diagnosis comprehensively and to explore their potential utility in cancer therapy when combined with the CRISPR/Cas system, offering novel insights and significant scientific contributions to the field.
