DOI: 10.1002/jmv.28553
Abstract: The severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2) caused global pandemic and drastically affected the humankind. Mitochondrial mutations have been found to be associated with several respiratory diseases. Missense mutation and pathogenic mitochondrial variants might unveil… read more here.

DOI: 10.1016/j.cmet.2018.05.010
Abstract: Mutations in mtDNA associated with OXPHOS defects preclude energy harnessing by OXPHOS. The work of Chen et al. (2018) is previewed, reporting flux pathways of glutamine catabolism in mtDNA mutant cells yielding high-energy phosphates through substrate-level… read more here.

DOI: 10.1016/j.mito.2021.02.012
Abstract: Mitochondrial DNA (mtDNA) mutations cause severe maternally inherited disorders, although mechanisms regulating mother-to-offspring transmission have not yet been elucidated. To investigate if mtDNA mutations affect embryonic development, we compared morphology, viability and mtDNA content in… read more here.

DOI: 10.1111/eva.12851
Abstract: Mitochondrial disorders are heterogeneous, showing variable presentation and penetrance. Over the last three decades, our ability to recognize mitochondrial patients and diagnose these mutations, linking genotype to phenotype, has greatly improved. However, it has become… read more here.

DOI: 10.1126/sciadv.adt3873
Abstract: Somatic mitochondrial DNA (mtDNA) mutations are frequently observed in tumors, yet their role in pediatric cancers remains poorly understood. The heteroplasmic nature of mtDNA—where mutant and wild-type mtDNA coexist—complicates efforts to define its contribution to… read more here.

DOI: 10.1126/science.adk7978
Abstract: Somatically acquired mitochondrial DNA mutations accumulate with age, but the mechanisms and consequences are poorly understood. Here we show that transient injuries induce a burst of persistent mtDNA mutations that impair resilience to future injuries.… read more here.
