Mitochondrial complex I deficiency leads to the retardation of early embryonic development in Ndufs4 knockout mice.

ABSTRACT: BACKGROUND:The NDUFS4 gene encodes an 18-kD subunit of mitochondria complex I, and mutations in this gene lead to the development of a severe neurodegenerative disease called Leigh syndrome (LS) in humans. 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 ed
