    Homozygous YME1L1 mutation causes mitochondriopathy with optic atrophy and mitochondrial network fragmentation

    Bianca Hartmann, Timothy Wai ... Angela M Kaindl
    Mutations affecting a nuclear encoded metalloprotease cause of a new form of mitochondriopathy, highlighting the importance of this protease for mitochondrial function in humans.

    Cytosolic aggregation of mitochondrial proteins disrupts cellular homeostasis by stimulating the aggregation of other proteins

    Urszula Nowicka, Piotr Chroscicki ... Agnieszka Chacinska
    Defective mitochondrial protein import results in protein aggregation and a specific chaperone response in the cytosol, causatively linking mitochondrial function and cellular protein homeostasis disturbances observed in neurodegeneration.

    Nicotinamide adenine dinucleotide is transported into mammalian mitochondria

    Antonio Davila, Ling Liu ... Joseph A Baur
    Stable isotope labeling reveals that NAD crosses the inner membrane of mammalian mitochondria via an unknown transporter.

    Cellular acidosis triggers human MondoA transcriptional activity by driving mitochondrial ATP production

    Blake R Wilde, Zhizhou Ye ... Donald E Ayer
    The MondoA transcription factor localizes to the outer mitochondrial membrane where it coordinates an adaptive transcriptional response to elevated cellular energy represented by high cytoplasmic glucose and high mitochondrial ATP.

    APOE expression and secretion are modulated by mitochondrial dysfunction

    Meghan E Wynne, Oluwaseun Ogunbona ... Victor Faundez
    Current models of Alzheimer's disease that put mitochondria as an endpoint of disease should be reconsidered because genetic defects affecting mitochondria by themselves can also regulate Alzheimer’s disease risk factor apolipoprotein E (APOE) expression and secretion.

    Proteomic mapping of cytosol-facing outer mitochondrial and ER membranes in living human cells by proximity biotinylation

    Victoria Hung, Stephanie S Lam ... Alice Y Ting
    One minute biotinylation with APEX2 peroxidase in living cells identifies established and new components of mitochondrial and ER membranes; dataset intersection and overexpression screen identifies SYNJ2BP overexpression as inducing mitochondria-rough ER contacts.

    Tom70-based transcriptional regulation of mitochondrial biogenesis and aging

    Qingqing Liu, Catherine E Chang ... Chuankai Zhou
    Tom70 connects the mitochondrial import to the nuclear transcriptional activity of mitochondrial proteins and controls mitochondrial biogenesis defects during aging.

    Respiratory syncytial virus co-opts host mitochondrial function to favour infectious virus production

    MengJie Hu, Keith E Schulze ... David A Jans
    RSV's unique ability to co-opt host cell mitochondria to facilitate viral infection reveals the RSV-mitochondrial interface as a viable target for therapeutic intervention.

    Maturation of selected human mitochondrial tRNAs requires deadenylation

    Sarah F Pearce, Joanna Rorbach ... Michal Minczuk
    Removal of spurious poly(A) tails by the PDE12 exoribonuclease is required to maintain the integrity of human mitochondrial tRNAs and rRNAs and their availability for efficient mitochondrial translation.

    Phosphate starvation signaling increases mitochondrial membrane potential through respiration-independent mechanisms

    Yeyun Ouyang, Mi-Young Jeong ... Jared Rutter
    SIT4 deletion and phosphate starvation increase mitochondrial membrane potential via electron transport chain dependent and independent manners, and the increased membrane potential induced by phosphate depletion is conserved between yeast, flies, and humans.
