    The identification of dual protective agents against cisplatin-induced oto- and nephrotoxicity using the zebrafish model

    Jaime N Wertman et al.
    L-mimosine and dopamine protect against cisplatin-induced oto- and nephrotoxicity in zebrafish and human cell line models.

    An atlas of neural crest lineages along the posterior developing zebrafish at single-cell resolution

    Aubrey GA Howard IV et al.
    Single-cell dissection of recent neural crest derivatives in the vertebrate zebrafish reveals diverse transcriptomic signatures among differentiating posterior cell types during the embryonic to larval stage transition.

    Mechanisms of virus dissemination in bone marrow of HIV-1–infected humanized BLT mice

    Mark S Ladinsky et al.
    Large-volume light microscopy combined with higher-resolution electron tomography revealed the spatial distribution of virus-producing cells and highlighted mechanisms of HIV-1 dissemination in bone marrow from a small animal model.

    Combinatorial chromatin dynamics foster accurate cardiopharyngeal fate choices

    Claudia Racioppi et al.
    ATAC-seq, CRISPR/Cas9 mutagenesis, reporter and gene expression assays revealed dynamic chromatin accessibility profiles governing differential gene expression during heart vs. pharyngeal muscle fate choices in the powerful chordate model Ciona.

    Evolutionary pathways of repeat protein topology in bacterial outer membrane proteins

    Meghan Whitney Franklin et al.
    There is a strand-based evolutionary mechanism for the diversification of outer membrane proteins, which has implications for how repeat proteins are created and for how outer membrane proteins fold.

    Proteasome storage granules protect proteasomes from autophagic degradation upon carbon starvation

    Richard S Marshall, Richard D Vierstra
    Proteasomes are protected from autophagic elimination upon carbon starvation by sequestration into cytoplasmic storage granules, which aid cell fitness by providing a cache of proteasomes that can be rapidly remobilized when carbon availability improves.

    The multi-subunit GID/CTLH E3 ubiquitin ligase promotes cell proliferation and targets the transcription factor Hbp1 for degradation

    Fabienne Lampert et al.
    Proteomic, biochemical and cell-based analyses of the heterodecameric core GID/CTLH E3 ligase complex reveal its molecular architecture, activity determinants, and function in targeting the tumor suppressor Hbp1 and other substrates required for cell proliferation.

    Membranes, energetics, and evolution across the prokaryote-eukaryote divide

    Michael Lynch, Georgi K Marinov
    The common view that the mitochondrion endowed eukaryotes with a boost in bioenergetic capacity above that in prokaryotes is inconsistent with a diversity of cellular features.

    Early intrinsic hyperexcitability does not contribute to motoneuron degeneration in amyotrophic lateral sclerosis

    Félix Leroy et al.
    Contrary to a long-standing hypothesis, the neuronal death that leads to muscle wastage in amyotrophic lateral sclerosis does not result from overactivity of those neurons during development.

    Maintenance of age in human neurons generated by microRNA-based neuronal conversion of fibroblasts

    Christine J Huh et al.
    MicroRNA-based direct conversion of human fibroblasts to neurons is applicable to fibroblasts from donors ranging in age from neonatal to centenarian, allowing the generation of neurons that maintain the age-associated signatures of the starting fibroblasts.
