    MicroRNA-934 is a novel primate-specific small non-coding RNA with neurogenic function during early development

    Kanella Prodromidou, Ioannis S Vlachos ... Rebecca Matsas
    Primate-specific miR-934 mediates neurogenesis and downstream neuronal differentiation processes, modulating the expression of genes associated with the subplate, a region most prominent in primates, emerging during early cortical development.

    Determining the effects of paternal obesity on sperm chromatin at histone H3 lysine 4 tri-methylation in relation to the placental transcriptome and cellular composition

    Anne-Sophie Pepin, Patrycja A Jazwiec ... Sarah Kimmins
    Epigenomic and transcriptomic analysis reveals that paternal obesity influences sperm histone H3 lysine 4 tri-methylation enrichment and placenta gene expression, which in turn negatively impact its development and function in a manner that may contribute to metabolic disease in offspring.

    Decreased recent adaptation at human mendelian disease genes as a possible consequence of interference between advantageous and deleterious variants

    Chenlu Di, Jesus Murga Moreno ... David Enard
    Harmful genetic variants at mendelian disease genes slow down adaptation, by interfering with the spread of adaptive variants in a population.

    Principles of self-organization and load adaptation by the actin cytoskeleton during clathrin-mediated endocytosis

    Matthew Akamatsu, Ritvik Vasan ... David G Drubin
    An experimentally constrained multiscale mathematical model predicts that branched actin networks self-organize at endocytic sites and bend to produce force, which was verified with cryo-electron tomography of intact cells.

    Molecular basis of synaptic specificity by immunoglobulin superfamily receptors in Drosophila

    Shouqiang Cheng, James Ashley ... Engin Özkan
    Fly protein families Dprs and DIPs can create a multitude of complementary interfaces for homo- and heterophilic adhesion complexes, resulting in instructive roles for connectivity in the motor neuron circuitry.

    Distinct skeletal stem cell types orchestrate long bone skeletogenesis

    Thomas H Ambrosi, Rahul Sinha ... Charles KF Chan
    Functional and molecular analyses of two distinct skeletal stem cell populations establish the important role of stem cell diversity that provides a framework for novel investigations into skeletal biology.

    Combining genotypes and T cell receptor distributions to infer genetic loci determining V(D)J recombination probabilities

    Magdalena L Russell, Aisha Souquette ... Philip Bradley
    Trans genetic variation in TdT and Artemis loci impacts V(D)J recombination probabilities.

    Naa12 compensates for Naa10 in mice in the amino-terminal acetylation pathway

    Hyae Yon Kweon, Mi-Ni Lee ... Gholson J Lyon
    Mice doubly deficient for Naa10 and Naa12 display embryonic lethality, with both enzymes compensating for each other with amino-terminal acetylation of proteins in mouse development.

    TGFβ signalling is required to maintain pluripotency of human naïve pluripotent stem cells

    Anna Osnato, Stephanie Brown ... Peter J Rugg-Gunn
    Identifying the pathways that support human naive-state pluripotent stem cells provides insights into the signalling-based regulation of human pluripotency and enables informed decisions to improve conditions for pluripotent cell culture.

    Consistent global structures of complex RNA states through multidimensional chemical mapping

    Clarence Yu Cheng, Fang-Chieh Chou ... Rhiju Das
    A multidimensional chemical mapping strategy enables confident determination of the structures of non-coding RNAs at 1-nm resolution, including previously intractable riboswitch and human regulon states.
