Advantages Over Traditional Methods

Traditional methods for delivering gene-editing tools into cells, especially primary cells, often present significant challenges. Electroporation, for instance, is a common technique but can be cytotoxic, meaning it can damage or kill the cells it aims to modify. Other chemical transfection methods may have limited efficiency, particularly for certain cell types, or can also induce toxicity. Viral vectors, while effective, can raise safety concerns related to immunogenicity and insertional mutagenesis.

Peptide-assisted genome editing aims to circumvent these issues. The engineered peptides can facilitate non-viral delivery, reducing the risk of immune responses. Furthermore, the precise design of these peptides allows for targeted delivery and enhanced cellular uptake, leading to higher editing efficiencies with significantly reduced toxicity. This is particularly crucial when working with primary cells, which are often more sensitive and difficult to manipulate than established cell lines. The ability to achieve "robust and nearly complete genome editing" in various cell types, including human cells and iPSCs, highlights the broad applicability and effectiveness of this approach.

Applications and Future Directions

The development of peptide-assisted genome editing opens up a wide array of applications in both basic research and potential clinical settings. In research, it allows for more precise and efficient genetic studies of cell function, disease modeling, and the development of novel cellular therapies. The ability to rapidly engineer primary cells with minimal toxicity is a game-changer for studying cell-specific gene functions and for developing personalized medicine approaches.Improved Genome Editing with Low Toxicity Using PAGE

Looking ahead, the field is exploring various peptide designs and delivery strategies. This includes optimizing peptide sequences for specific cell types, developing peptide nanoparticles for enhanced delivery, and integrating these methods with advanced gene-editing techniques like prime editing, which allows for even more precise modifications than standard CRISPR-Cas9. The continuous innovation in peptide-assisted genome editing promises to further refine efficiency, reduce toxicity, and expand the scope of genomic engineering, bringing us closer to unlocking the full potential of gene editing for human health and scientific discovery.作者：RG Cuomo·2024·被引用次数：1—Peptide-Assisted Genome Editing (PAGE)provides a simple, modular, and rapid approachfor the protein-based delivery of CRISPR-Cas proteins or ribonucleoprotein ...
