    Functional limb muscle innervation prior to cholinergic transmitter specification during early metamorphosis in Xenopus

    Francois M Lambert et al.
    Molecular labeling, electrophysiology and calcium imaging have revealed a novel switching of neurotransmitter at the frog neuromuscular junction where motoneurons transiently release glutamate before acetylcholine at synapses on developing hindlimb muscles at the onset of metamorphosis.

    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.

    Attenuation of dopamine-modulated prefrontal value signals underlies probabilistic reward learning deficits in old age

    Lieke de Boer et al.
    Attenuated anticipatory activity in ventromedial prefrontal cortex is modulated by dopamine D1 receptor density in nucleus accumbens, and accounts for impaired probabilistic reward learning in older adults.

    Single-protein detection in crowded molecular environments in cryo-EM images

    J Peter Rickgauer et al.
    High-resolution template matching makes small, densely embedded proteins detectable.

    Transcriptional networks specifying homeostatic and inflammatory programs of gene expression in human aortic endothelial cells

    Nicholas T Hogan et al.
    An integrative genome-wide approach supports a direct and collaborative role of ETS and AP-1 transcription factors in maintaining endothelial cell-specific and anti-inflammatory gene expression programs.

    Global reorganisation of cis-regulatory units upon lineage commitment of human embryonic stem cells

    Paula Freire-Pritchett et al.
    Promoter interactome maps in human embryonic stem cells (ESCs) and ESC-derived early neuroectodermal progenitors link distal enhancers to putative target genes, reveal lineage-specific cis-regulatory architecture and shed light on the logic of gene regulation by multiple enhancers.

    USP5/Leon deubiquitinase confines postsynaptic growth by maintaining ubiquitin homeostasis through Ubiquilin

    Chien-Hsiang Wang et al.
    Maintenance of ubiquitin homeostasis is essential for proper control of the size of postsynaptic density and the growth of specialized membrane structure.

    Codon optimization underpins generalist parasitism in fungi

    Thomas Badet et al.
    Codon optimization through biased synonymous substitutions is a characteristic feature of the genomes of generalist fungal parasites and is associated with the colonization of multiple hosts.

    Astrocyte morphology is confined by cortical functional boundaries in mammals ranging from mice to human

    Raya Eilam et al.
    The structural morphology of astrocyte processes is constrained by functional boundaries in the mouse, rat and human cortex.

    An extensive program of periodic alternative splicing linked to cell cycle progression

    Daniel Dominguez et al.
    Extensive periodic regulation of alternative splicing during the cell cycle in genes is linked to cell cycle functions, and involves an auto-inhibitory mechanism that uses the protein kinase CLK1.
