Researchers from Hiroshima University and the Japanese National Institute of Advanced Industrial Science and Technology are leveraging machine-learning modeling tools to enhance zinc-finger nuclease editing technology, further advancing genome editing capabilities in biomedical research and medicine.
The study, recently published in Advanced Science, highlights how a Japanese research team is utilizing modular assembly systems driven by machine learning to refine gene editing processes. Shota Katayama, an associate professor at Hiroshima University’s Genome Editing Innovation Center, emphasized the importance of improving gene editing technologies to achieve greater precision in modifying genetic information in living cells.
Zinc finger nuclease (ZFN) is a vital tool in genome editing alongside CRISPR/Cas9 and TALEN. ZFNs are engineered to break specific bonds within DNA molecules, consisting of DNA-binding and DNA-cleavage domains. Unlike CRISPR/Cas9, ZFN patents have expired, eliminating high patent royalties for industrial applications and offering potential cost savings. Furthermore, ZFNs are smaller in size, making them suitable for in vivo and clinical applications due to their ease of packaging into viral vectors with limited cargo space.
Constructing functional ZFNs and enhancing their genome editing efficiency has posed challenges, prompting the researchers to aim for a more efficient and easily constructed ZFN using modular assembly systems. By incorporating biomolecule modeling tools like AlphaFold, Coot, and Rosetta, the team successfully engineered ZFNs with increased genome editing efficiency, showcasing a 5% improvement in editing capabilities.
Through the collaborative efforts of Hiroshima University and the Japanese National Institute of Advanced Industrial Science and Technology, the study demonstrates the potential of utilizing machine learning-driven modeling tools to advance gene editing technologies, offering promising prospects for the treatment of genetic disorders across various fields.
