PRINT, a new gene therapy technique, employs bird-derived retrotransposons to insert whole genes into a safe zone of the human genome, offering a complementary approach to CRISPR-Cas9 by potentially enabling the treatment of diseases without the risk of gene disruption or cancer. Credit: SciTechDaily.com Retrotransposons found in the genomes of the white-throated sparrow and the zebra finch are shown to safely shepherd transgenes into the human genome, providing a gene therapy approach complementary to CRISPR-Cas9 gene editing.
