    Genome-wide quantification of the effects of DNA methylation on human gene regulation

    Amanda J Lea, Christopher M Vockley ... Jenny Tung
    mSTARR-seq identifies regions of the genome where DNA methylation causally impacts gene expression, providing a map of which epigenetic marks may influence trait variation.

    A frameshift in Yersinia pestis rcsD alters canonical Rcs signalling to preserve flea-mammal plague transmission cycles

    Xiao-Peng Guo, Hai-Qin Yan ... Yi-Cheng Sun
    Pseudogenization of rcsD alters canonical Rcs phosphorelay signalling and marks a significant adaptive evolutionary step in the emergence of ubiquitous extant branches of Yersinia pestis that can maintain stable plague outbreaks.

    The homo-oligomerisation of both Sas-6 and Ana2 is required for efficient centriole assembly in flies

    Matthew A Cottee, Nadine Muschalik ... Susan M Lea
    The structure of the Ana2 Central Coiled-Coil Domain provides insight into how centriolar cartwheel components may be recruited and assembled, and indicates that cartwheel assembly involves more than just SAS-6 oligomerisation.

    Functional membrane microdomains and the hydroxamate siderophore transporter ATPase FhuC govern Isd-dependent heme acquisition in Staphylococcus aureus

    Lea Antje Adolf, Angelika Müller-Jochim ... Simon Heilbronner
    Staphylococcal heme acquisition needs a highly structured cell envelope, the membrane transporter accumulates in membrane domains most likely to allow concerted passage of heme from the cell wall-funnel to the membrane.

    Telomere dysfunction cooperates with epigenetic alterations to impair murine embryonic stem cell fate commitment

    Mélanie Criqui, Aditi Qamra ... Lea Harrington
    Cell lineage tracing and biochemical analysis of cell fate during murine stem cell differentiation demonstrates a specific cooperativity between perturbations in histone methylation and eroded telomeres that destabilize cell differentiation.

    A conserved strategy for inducing appendage regeneration in moon jellyfish, Drosophila, and mice

    Michael J Abrams, Fayth Hui Tan ... Lea Goentoro
    Amino acid and sugar supplement induce appendage/limb regeneration in cnidarians, insects, and mammals.

    Signaling pathways as linear transmitters

    Harry Nunns, Lea Goentoro
    Mathematical and experimental analyses suggest that despite their complex architectures, multiple metazoan signaling pathways act in physiological contexts as linear signal transmitters.

    Identification of electroporation sites in the complex lipid organization of the plasma membrane

    Lea Rems, Xinru Tang ... Lucie Delemotte
    Advanced data analysis of molecular dynamics simulations of complex lipid membranes provides a quantitative and predictive model of the molecular features that control electroporation.

    Process- and product-related impurities in the ChAdOx1 nCov-19 vaccine

    Lea Krutzke, Reinhild Rösler ... Stefan Kochanek
    Analysis of protein content and protein composition of the ChAdOx1 nCov-19 vaccine, but not of the Ad26.COV2.S vaccine, indicated significantly higher than expected levels of host cell proteins (HCPs) and of free viral proteins.

    Competition between antagonistic complement factors for a single protein on N. meningitidis rules disease susceptibility

    Joseph JE Caesar, Hayley Lavender ... Susan M Lea
    Genetic susceptibility to an infectious disease is linked to competition for binding a molecule on the bacterial surface by two host proteins with opposing roles in host immunity.
