Mitochondrial dysfunctions predominantly cause encephalomyopathies with muscle atrophy and neurodegeneration. However, their impact on other tissues, particularly the gastrointestinal tract, requires further investigation. In a recent report in Nature, Moschandrea et al. used mice deficient in the mitochondrial aminoacyl-tRNA synthetase DARS2 to investigate the role of enterocytic mitochondria in dietary lipid processing and transport. Their work sheds light on the development of gastrointestinal disorders as a result of mitochondrial dysfunction.
Keywords: DARS2; gastrointestinal disorders; lipid processing; mitochondria; mitochondrial aminoacyl-tRNA synthetases (mt-AaRSs).
