    Sox17 and β-catenin co-occupy Wnt-responsive enhancers to govern the endoderm gene regulatory network

    Shreyasi Mukherjee et al.
    Genomic analysis of Xenopus gastrula reveal that the transcription factor Sox17 interacts with the Wnt signaling effector ß-catenin on enhancers to regulate the transcriptional program underlying endoderm germ layer formation.

    Size-dependent patterns of cell proliferation and migration in freely-expanding epithelia

    Matthew A Heinrich et al.
    Epithelia exhibit size-dependent growth dynamics caused by a decoupling between boundary and bulk cellular dynamics that enable robust expansion and drive cell cycling, collective migration, and tissue-spanning vortices.

    Coverage-dependent bias creates the appearance of binary splicing in single cells

    Carlos F Buen Abad Najar et al.
    Sequencing and counting RNAs from single cells can create a misleading picture of alternative splicing if too many mRNAs are lost in the process.

    Quantitative mapping of transcriptome and proteome dynamics during polarization of human iPSC-derived neurons

    Feline W Lindhout et al.
    A dynamic qualitative and quantitative map of human iPSC-derived neuronal stem cells transitioning into polarized neurons with the identification and characterization of a previously unrecognized axon developmental stage.

    MAPK activity dynamics regulate non-cell autonomous effects of oncogene expression

    Timothy J Aikin et al.
    The temporal patterns of MAPK activity differentially regulate cell autonomous and non-cell autonomous effects of oncogene expression.

    Convergent changes in muscle metabolism depend on duration of high-altitude ancestry across Andean waterfowl

    Neal J Dawson et al.
    Changes in pathways of lipid oxidation, glycolysis, and mitochondrial oxidative phosphorylation are common strategies to cope with high-altitude hypoxia, but some changes require longer evolutionary time to arise.

    ZCWPW1 is recruited to recombination hotspots by PRDM9 and is essential for meiotic double strand break repair

    Daniel Wells et al.
    ZCWPW1 has co-evolved with PRDM9, in particular the PRDM9-SET domain, and although not involved in PRDM9's role in positioning recombination events, it is required for PRDM9's role in pairing chromosomes.

    Clusters of polymorphic transmembrane genes control resistance to schistosomes in snail vectors

    Jacob A Tennessen et al.
    A region of the Biomphalaria genome, containing highly divergent haplotypes with different combinations of transmembrane genes, strongly impacts whether these snails can transmit parasitic schistosomes.

    Complement opsonization of HIV affects primary infection of human colorectal mucosa and subsequent activation of T cells

    Pradyot Bhattacharya et al.
    Complement opsonized HIV exposure gives rise to a colorectal mucosal environment with an initial suppressed antiviral response and increased infection of immune cells and altered activation of T cells.

    Cortical RORβ is required for layer 4 transcriptional identity and barrel integrity

    Erin A Clark et al.
    RORβ is a key layer 4 transcription factor orchestrating a critical juncture in barrel development where terminal differentiation and activity inputs are integrated to drive cellular organization in the cortex.
