To investigate the disease phenotypes and molecular mechanisms of Leigh syndrome, the Ndufs4 knockout (KO) mouse has been widely used as a novel animal model. Because the homozygotes cannot survive beyond child-bearing age, whether Ndufs4 and mitochondrial complex I influence early embryonic development remains unknown. In our study, we attempted to investigate embryonic development in Ndufs4 KO mice, which can be regarded as a Leigh disease model and were created through the CRISPR (clustered regularly interspaced short palindromic repeat) and Cas9 (CRISPR associated)-mediated genome editing system %K Mitochondria complex I %K Ndufs4 %K CRISPR/Cas9 %K Embryo development %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5438584/
