CRISPR/Cas9-mediated genome editing induces gene knockdown by altering the pre-mRNA splicing in mice.

abstract：BACKGROUND:Chinese hamster ovary (CHO) cells have become the host of choice for the production of recombinant proteins, due to their capacity for correct protein folding, assembly, and posttranslational modifications. The most widely used system for recombinant proteins is the gene amplification procedure that uses the...
