Generation of genetically engineered mouse models (GEMMs) for chromosomal translocations in the endogenous loci by a knockin strategy is lengthy and costly. The CRISPR/Cas9 system provides an innovative and flexible approach for genome engineering of genomic loci in vitro and in vivo. Here, we report the use of the CRISPR/Cas9 system for engineering a specific chromosomal translocation in adult mice in vivo. We designed CRISPR/Cas9 lentiviral vectors to induce cleavage of the murine endogenous Eml4 and Alk loci in order to generate the Eml4-Alk gene rearrangement recurrently found in non-small-cell lung cancers (NSCLCs). Intratracheal or intrapulmonary inoculation of lentiviruses induced Eml4-Alk gene rearrangement in lung cells in vivo. Genomic and mRNA sequencing confirmed the genome editing and the production of the Eml4-Alk fusion transcript. All mice developed Eml4-Alk-rearranged lung tumors 2 months after the inoculation, demonstrating that the CRISPR/Cas9 system is a feasible and simple method for the generation of chromosomal rearrangements in vivo. |
