A streamlined protocol for an alternative gene insertion method using genome editing technologies, the PITCh (Precise Integration into Target Chromosome) system, has been reported in Nature Protocols by Specially Appointed Lecturer Tetsushi Sakuma, Professor Takashi Yamamoto, Specially Appointed Associate Professor Ken-Ichi T Suzuki, and their colleagues at Hiroshima University, Japan.
The PITCh system is more convenient and effective than existing methods for inserting foreign DNA into targeted genomic loci by using genome-editing tools. This new versatile technique can aid the rapid progression of research in fields such as screening of new drug candidates and creating cell or animal models of human diseases.
Genome editing is an innovative technique used in genetic engineering that enables researchers to modify the genome not at random but at a particular target. In this technique, researchers employ engineered nucleases as “molecular scissors”, which create DNA breaks at desired locations in the genome. When DNA breaks are repaired by repair pathways, genetic modifications including insertion of foreign DNA into the genome (knock-in) and replacement or removal of a targeted genomic locus are induced.
