    N-myc downstream regulated gene 1 (ndrg1) functions as a molecular switch for cellular adaptation to hypoxia

    Jong S Park, Austin M Gabel ... Rachel Brewster
    Lactate-Ndrg1a signaling protects the kidney from hypoxic injury and functions partly by inducing reversible degradation of the ATP-demanding sodium-potassium ATPase pump.

    Unrestrained growth of correctly oriented microtubules instructs axonal microtubule orientation

    Maximilian AH Jakobs, Assaf Zemel, Kristian Franze
    Biased growth of microtubules in the advancing axon tip contributes to the uniform orientation of microtubules in mature axons, which is essential for proper neuronal functioning.

    Fitness effects of CRISPR endonucleases in Drosophila melanogaster populations

    Anna M Langmüller, Jackson Champer ... Philipp W Messer
    In Drosophila, genomic CRISPR/Cas9 expression necessary for CRISPR-based gene drives harbors fitness costs presumably caused by off-target effects, which can be minimized by using a high-fidelity version of Cas9.

    Post-phagocytosis activation of NLRP3 inflammasome by two novel T6SS effectors

    Hadar Cohen, Noam Baram ... Motti Gerlic
    A horizontally shared type VI secretion system affects the interaction between vibrios and eukaryotic hosts.

    SARS-CoV-2 antibody dynamics in blood donors and COVID-19 epidemiology in eight Brazilian state capitals: A serial cross-sectional study

    Carlos A Prete Jr, Lewis F Buss ... Ester C Sabino
    Blood donor serosurveillance in eight of Brazil’s most populous cities reveals extensive variation of SARS-CoV-2 attack rate across cities, age, and sex groups in December 2020 and increased intrinsic severity of the Gamma variant of concern.

    Kinesin-1, -2, and -3 motors use family-specific mechanochemical strategies to effectively compete with dynein during bidirectional transport

    Allison M Gicking, Tzu-Chen Ma ... William O Hancock
    The motility of three different kinesin-dynein pairs were analyzed and found to be strikingly similar, suggesting that bidirectional transport is not regulated by motor type, but rather by scaffold, adapter, and regulatory proteins.

    De novo apical domain formation inside the Drosophila adult midgut epithelium

    Jia Chen, Daniel St Johnston
    Drosophila enteroblasts form septate junctions, an apical domain and an internal lumen inside the midgut epithelium before they reach the gut surface, thereby maintaining the intestinal barrier as they integrate.

    BRCA2 BRC missense variants disrupt RAD51-dependent DNA repair

    Judit Jimenez-Sainz, Joshua Mathew ... Ryan B Jensen
    Novel variants in the BRC repeat region of BRCA2 were identified and comprehensively characterized as either deleterious or benign.

    Estimating the potential to prevent locally acquired HIV infections in a UNAIDS Fast-Track City, Amsterdam

    Alexandra Blenkinsop, Mélodie Monod ... Oliver Ratmann
    Phylogenetic evidence suggests that the majority of HIV infections occurring in the UNAIDS Fast-track city Amsterdam continue to have an Amsterdam resident as source, indicating that the majority of HIV infections in Amsterdam could be prevented through city-level interventions.

    A single-cell atlas of the cycling murine ovary

    Mary E Morris, Marie-Charlotte Meinsohn ... David Pépin
    A survey of the transcriptomic landscape of the mouse ovary at the single-cell level reveals both the cellular complexity of this organs and the dynamic nature of the cellular states that accompany estrous cycling.
