    The mechanism of error induction by the antibiotic viomycin provides insight into the fidelity mechanism of translation

    Mikael Holm, Chandra Sekhar Mandava ... Suparna Sanyal
    The antibiotic viomycin induces errors during initial codon selection by the ribosome by locking the monitoring bases in their active conformation.

    Chronic neurotransmission increases the susceptibility of lateral-line hair cells to ototoxic insults

    Daria Lukasz, Alisha Beirl, Katie Kindt
    In vivo imaging reveals that the synaptic vesicle cycle is a significant contributor to oxidative stress in sensory hair cells, rendering them susceptible to insults.

    Cumulative mitochondrial activity correlates with ototoxin susceptibility in zebrafish mechanosensory hair cells

    Sarah B Pickett, Eric D Thomas ... David W Raible
    The history of mitochondrial activity predicts whether zebrafish mechanosensory hair cells live or die after toxic drug exposure.

    A homozygous FANCM mutation underlies a familial case of non-syndromic primary ovarian insufficiency

    Baptiste Fouquet, Patrycja Pawlikowska ... Micheline Misrahi
    Bilallelic mutations of FANCM, a DNA-damage response gene whose heterozygous mutations predispose to breast cancer, are involved in a familial case of Primary Ovarian Insufficiency establishing a link between infertility and cancer.

    Pregnancy-associated plasma protein-aa supports hair cell survival by regulating mitochondrial function

    Mroj Alassaf, Emily C Daykin ... Marc A Wolman
    Hair cell survival and mitochondrial function is supported by an extracellular stimulator of IGF1 signaling, the protease pregnancy-associated plasma protein-aa.

    Long-term intravital imaging of the multicolor-coded tumor microenvironment during combination immunotherapy

    Shuhong Qi, Hui Li ... Zhihong Zhang
    Tregs form an "immunosuppressive ring" around solid tumors that is broken down during adoptive cell therapy and cyclophosphamide combination immunotherapy.

    Differences across cyclophilin A orthologs contribute to the host range restriction of hepatitis C virus

    Jenna M Gaska, Metodi Balev ... Alexander Ploss
    Incompatibilities between the viral replication machinery and orthologs of the essential host factor cyclophilin A (CypA) contribute to the narrow host range of hepatitis C virus.

    Collagen polarization promotes epithelial elongation by stimulating locoregional cell proliferation

    Hiroko Katsuno-Kambe, Jessica L Teo ... Alpha S Yap
    Integrin- and ERK signaling stimulates mammary epithelial cell proliferation when extracellular collagen condenses, causing asymmetric growth of multicellular aggregates that is necessary for elongation during branching morphogenesis.

    Resurrection of a global, metagenomically defined gokushovirus

    Paul C Kirchberger, Howard Ochman
    Isolation of a gokushovirus capable of lysogenizing enterobacteria challenges previous notions about the biology of the most prolific phages within the Microviridae and facilitates experimental study in a model organism.
