    Human embryo polarization requires PLC signaling to mediate trophectoderm specification

    Meng Zhu, Marta Shahbazi ... Magdalena Zernicka Goetz
    Functional analyses of in vitro fertilized, preimplanation human embryos reveal that the first lineage segregation depends on cell polarization signaling that is regulated by Phospholipase C (PLC) activity.

    Barcoded bulk QTL mapping reveals highly polygenic and epistatic architecture of complex traits in yeast

    Alex N Nguyen Ba, Katherine R Lawrence ... Michael M Desai
    A bulk barcoded quantitative trait locus approach increases the power and resolution of genotype-phenotype mapping in yeast, revealing that the genetic architecture of 18 complex traits is highly polygenic, and is characterized by widespread epistatic interactions and pleiotropic effects.

    Simple biochemical features underlie transcriptional activation domain diversity and dynamic, fuzzy binding to Mediator

    Adrian L Sanborn, Benjamin T Yeh ... Roger D Kornberg
    Transcriptional activation domains achieve rapid, dynamic, specific interaction with Mediator through binding of an unstructured peptide to multiple hydrophobic surfaces without particular amino acid side chain interactions.

    Empirical single-cell tracking and cell-fate simulation reveal dual roles of p53 in tumor suppression

    Ann Rancourt, Sachiko Sato, Masahiko S Satoh
    Single-cell tracking and cell-fate simulation suggest that low levels of p53 suppress aneuploid cell formation in unstressed cells and also reveal the dual fate of cells lacking p53 in the presence of p53-proficient cells.

    Genetics of trans-regulatory variation in gene expression

    Frank Wolfgang Albert, Joshua S Bloom ... Leonid Kruglyak
    A genetic mapping study in more than 1000 yeast individuals reveals the complexity of trans-acting genetic influences on transcriptome variation in unprecedented depth and detail.

    The transition state and regulation of γ-TuRC-mediated microtubule nucleation revealed by single molecule microscopy

    Akanksha Thawani, Michael J Rale ... Sabine Petry
    Four αβ-tubulin dimers associate laterally on γ-TuRC to define the rate-limiting transition state for microtubule nucleation.

    Proteomic mapping of cytosol-facing outer mitochondrial and ER membranes in living human cells by proximity biotinylation

    Victoria Hung, Stephanie S Lam ... Alice Y Ting
    One minute biotinylation with APEX2 peroxidase in living cells identifies established and new components of mitochondrial and ER membranes; dataset intersection and overexpression screen identifies SYNJ2BP overexpression as inducing mitochondria-rough ER contacts.

    CTCF and cohesin regulate chromatin loop stability with distinct dynamics

    Anders S Hansen, Iryna Pustova ... Xavier Darzacq
    Single-molecule imaging of CTCF and cohesin in live cells suggests that chromatin loops are dynamic structures that frequently form and fall apart.
