Advancing CRISPR base editing technology through innovative strategies and ideas

Area of Science:

• Molecular Biology
• Biotechnology
• Genetics

Background:

• CRISPR/Cas gene editing technology has seen rapid development and diverse applications.
• Idealized gene editors remain a future goal across various scientific fields.

Purpose of the Study:

• To explore the development and innovation of non-DNA double-strand break (non-DSB) editors: base editors (BE) and prime editors (PE).
• To analyze improvement strategies and conceptual leaps in CRISPR technology.
• To review efforts in developing smaller editors for Adeno-Associated Virus (AAV) delivery and their in vivo applications.

Main Methods:

• Review of innovation strategies ('substitution', 'combination', 'adaptation', 'adjustment') applied to BE and PE development.
• Analysis of conceptual advancements in CRISPR technology.
• Summary of current research on small editor development for AAV delivery systems.

Main Results:

• BE and PE represent significant innovations in CRISPR technology, enabling precise gene modification without DNA double-strand breaks.
• Development of smaller editors is crucial for overcoming AAV packaging limitations.
• AAV-mediated in vivo gene modification using these editors is an active area of research.

Conclusions:

• CRISPR/Cas innovation, particularly with BE and PE, offers powerful tools for various applications.
• Further development of small, efficient editors is essential for advancing in vivo gene editing therapies.
• The future holds promise for the development of idealized gene editors.
