In the long human effort to mend broken genes, researchers at UC Berkeley have found an unlikely ally in the DNA of songbirds. A new technique called PRINT borrows a self-copying genetic element from species like the zebra finch to place therapeutic genes not randomly into the genome, but into a carefully chosen sanctuary — the ribosomal RNA regions, where hundreds of redundant copies absorb the insertion without harm. Published in Nature Biotechnology in February 2024, the work offers a path toward gene therapies that could treat entire patient populations regardless of which specific mutatio
