Summary
Refined CRISPR tools that rewrite single bases or short sequences without making double-strand breaks.
In depth
Base editors fuse a nickase Cas9 to a deaminase to convert C to T or A to G without a double-strand break. Prime editing uses a pegRNA and reverse transcriptase to write small insertions, deletions or all base changes. Liu's lab developed both.
Avoiding double-strand breaks reduces unintended indels and chromosomal rearrangements. Delivery of editors remains a hurdle. Precision is critical for therapeutic use.
Example: prime editing can correct many pathogenic variants in cell models.
