Prime editing: advances and therapeutic applications.

Area of Science:

• Biotechnology
• Genetics
• Molecular Biology

Background:

• CRISPR-Cas9 gene editing has transformed biomedical research but has limitations in precise mutation repair for gene therapy.
• DNA double-strand break (DSB) repair pathways activated by CRISPR-Cas9 are insufficient for certain therapeutic applications.

Purpose of the Study:

• To summarize recent advancements in prime editing technology.
• To highlight optimized prime editor (PE) variants with enhanced efficiency and precision.
• To discuss potential therapeutic applications of prime editing.

Main Methods:

• Review of recent literature on prime editing technology development.
• Analysis of optimized prime editor variants and their performance.
• Exploration of potential therapeutic uses based on current research.

Main Results:

• Prime editing enables precise base substitutions, insertions, and deletions without inducing DSBs.
• Newer prime editor variants demonstrate improved editing efficiency and precision.
• Prime editing shows promise for various therapeutic applications, though further development is required.

Conclusions:

• Prime editing represents a significant advancement in genome editing beyond CRISPR-Cas9.
• Continued optimization of prime editor variants and delivery strategies is crucial for clinical translation.
• Prime editing holds considerable potential for future gene therapy and diagnostics.
