Whole-Genome Sequencing Reveals Rare Off-Target Mutations in MC1R-Edited Pigs Generated by Using CRISPR-Cas9 and Somatic Cell Nuclear Transfer.
The clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 system has been widely used to create animal models for biomedical and agricultural use owing to its low cost and easy handling. However, the occurrence of erroneous cleavage (off-targeting) may raise certain concerns for the practical application of the CRISPR-Cas9 system. In this study, we created a melanocortin 1 receptor (MC1R)-edited pig model through somatic cell nuclear transfer (SCNT) by using porcine kidney cells modified by the CRISPR-Cas9 system. We then carried out whole-genome sequencing of two MC1R-edited pigs and two cloned wild-type siblings, together with the donor cells, to assess the genome-wide presence of single-nucleotide variants and small insertions and deletions (indels) and found only one candidate off-target indel in both MC1R-edited pigs. In summary, our study indicates that the minimal off-targeting effect induced by CRISPR-Cas9 may not be a major concern in gene-edited pigs created by SCNT.

期刊介绍:
In recognition of this extraordinary scientific and technological era, Mary Ann Liebert, Inc., publishers recently announced the creation of The CRISPR Journal -- an international, multidisciplinary peer-reviewed journal publishing outstanding research on the myriad applications and underlying technology of CRISPR.
Debuting in 2018, The CRISPR Journal will be published online and in print with flexible open access options, providing a high-profile venue for groundbreaking research, as well as lively and provocative commentary, analysis, and debate. The CRISPR Journal adds an exciting and dynamic component to the Mary Ann Liebert, Inc. portfolio, which includes GEN (Genetic Engineering & Biotechnology News) and more than 80 leading peer-reviewed journals.
