    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.

    Chromatinization of Escherichia coli with archaeal histones

    Maria Rojec et al.
    Escherichia coli is surprisingly tolerant to chromatinization by archaeal histones, suggesting that histones can become established as ubiquitous chromatin proteins without interfering critically with some key DNA-templated processes.

    Lactate-mediated epigenetic reprogramming regulates formation of human pancreatic cancer-associated fibroblasts

    Tushar D Bhagat et al.
    Lactate in pancreatic cancer micro-environment can lead to TET enzyme activation and loss of DNA methylation seen in cancer associated fibroblasts.

    Retinal direction selectivity in the absence of asymmetric starburst amacrine cell responses

    Laura Hanson et al.
    Experimental and computational models reveal how parallel 'core' mechanisms shape direction selectivity at the dendrites of starburst amacrine cells and ganglion cells in the mouse retina.

    GPIHBP1 expression in gliomas promotes utilization of lipoprotein-derived nutrients

    Xuchen Hu et al.
    The expression of the lipoprotein lipase (LPL) transporter GPIHBP1 in glioma capillaries promotes the LPL-mediated processing of triglyceride-rich lipoproteins, thereby providing lipid nutrients for glioma cells.

    Sleep-promoting effects of threonine link amino acid metabolism in Drosophila neuron to GABAergic control of sleep drive

    Yoonhee Ki, Chunghun Lim
    Threonine promotes sleep via down-regulation of metabotropic GABA transmission in the ellipsoid body R2 neurons that generate homeostatic sleep drive in Drosophila.

    The functional organization of excitation and inhibition in the dendrites of mouse direction-selective ganglion cells

    Varsha Jain et al.
    Accurate direction-selective information is present within small sections of the dendrites, raising the possibility that single dendrites utilize parallel processing schemes to process motion information.

    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.

    SLC6A14, an amino acid transporter, modifies the primary CF defect in fluid secretion

    Saumel Ahmadi et al.
    Loss of an amino acid transporter and tissue depletion of nitric oxide worsens the intestinal function of CF mice, a finding that potentially explains variation in disease severity amongst CF individuals.

    Cooperative interactions enable singular olfactory receptor expression in mouse olfactory neurons

    Kevin Monahan et al.
    Biochemical and genetic experiments show that Ebf and Lhx2 cooperate to specify olfactory receptor enhancers, which cooperate to drive olfactory receptor expression.
