    Hepatic inactivation of murine Surf4 results in marked reduction in plasma cholesterol

    Vi T Tang, Joseph McCormick ... David Ginsburg
    Inactivation of SURF4 leads to impaired secretion of PCSK9 and apolipoproteins resulting in low plasma cholesterol without detrimental consequences to the liver.

    Transiently heritable fates and quorum sensing drive early IFN-I response dynamics

    Laura C Van Eyndhoven, Vincent PG Verberne ... Jurjen Tel
    Early IFN-I response dynamics are initiated in only fractions of cells, of which their epigenetic profile is transiently heritable and subject to the effects of quorum sensing.

    P2Y1 purinergic receptor identified as a diabetes target in a small-molecule screen to reverse circadian β-cell failure

    Biliana Marcheva, Benjamin J Weidemann ... Joseph Bass
    A genetically sensitized drug screen identifies a circadian diabetes target and establishes a novel discovery pathway to treat β-cell failure.

    Extensive site-directed mutagenesis reveals interconnected functional units in the alkaline phosphatase active site

    Fanny Sunden, Ariana Peck ... Daniel Herschlag
    Conventional studies have focused on enzymatic residues directly involved in catalysis; dissecting a potential interaction network within which these ‘catalytic residues’ are embedded provides insights fundamental to enzyme function, evolution, and engineering.

    Genome-wide base editor screen identifies regulators of protein abundance in yeast

    Olga T Schubert, Joshua S Bloom ... Leonid Kruglyak
    A CRISPR/Cas9 base editor screen allows probing interactions between large numbers of known mutations and the abundance of specific proteins to study the protein regulatory network in yeast.

    A virus-packageable CRISPR screen identifies host factors mediating interferon inhibition of HIV

    Molly OhAinle, Louisa Helms ... Michael Emerman
    Host restriction factors that block cross-species transmission also play a role in limiting the replication of highly-adapted HIV-1 in IFN-stimulated cells.

    Science Forum: A survey of research quality in core facilities

    Isabelle C Kos-Braun, Björn Gerlach, Claudia Pitzer
    Responses to a survey reveal how core facilities could improve and encourage good research practices.

    Parallel CRISPR-Cas9 screens clarify impacts of p53 on screen performance

    Anne Ramsay Bowden, David A Morales-Juarez ... Stephen P Jackson
    The protein p53 negatively impacts the ability of a CRISPR screen to discriminate between essential and non-essential genes, hence, p53 status should be considered in these screens.

    Relationship between changing malaria burden and low birth weight in sub-Saharan Africa: A difference-in-differences study via a pair-of-pairs approach

    Siyu Heng, Wendy P O'Meara ... Dylan S Small
    A novel pair-of-pairs matching approach finds that community-level reductions in malaria burden can potentially substantially reduce the low birth weight rate in sub-Saharan Africa, particularly among firstborns.

    Capturing change in clonal composition amongst single mouse germinal centers

    Daniel J Firl, Soren E Degn ... Michael C Carroll
    Repeated interrogation of single germinal centers in vivo reveals a more fluid landscape than expected and unlocks new lines of investigation.
