The accumulation of acquired mitochondrial genome (mtDNA) mutations with aging in somatic cells has been implicated in mitochondrial dysfunction and linked to age-onset diseases in humans. Here, we asked if somatic mtDNA mutations are also associated with aging in the mouse. MtDNA integrity in multiple organs and tissues in young and old (2–34 months) wild type (wt) mice was investigated by whole genome sequencing. Remarkably, no acquired somatic mutations were detected in tested tissues. Howeve...

Genome editing could be applied to correct disease-causing mutations in human embryos, but concerns about efficacy and safety are paramount. Shoukhrat Mitalipov and colleagues use CRISPRCas9 to correct a heritable cardiomyopathy mutation in human embryos. By optimizing the experimental conditions, the authors show very reduced mosaicism, and report that for this heterozygous mutation, CRISPRCas9-induced breaks seem to be preferentially repaired using the wild-type allele as a template in human e...
