Summarized by Masters of Longevity from Nature - Main.
A methods-focused article describing a new RNA-guided approach for assembling and rearranging large DNA sequences in human cells, useful for researchers interested in advanced genome-engineering techniques.
Key Takeaways
- Prime assembly enabled targeted RNA-guided integration of medium-to-large DNA sequences without requiring double-strand breaks.
- Codon-optimized ssDNA donors produced up to ~33% exon-recoding edits in K562 cells using prime assembly.
- Prime assembly supported long ssDNA transgene integration and megabase-scale rearrangements, with detectable alleles in primary CD34+ HSPCs.
