    Duox-generated reactive oxygen species activate ATR/Chk1 to induce G2 arrest in Drosophila tracheoblasts

    Amrutha Kizhedathu, Piyush Chhajed ... Arjun Guha
    Reactive oxygen species can activate the ATR/Chk1 pathway in the absence of detectable DNA damage and without a requirement for DNA damage response proteins.

    Cryo-EM reconstructions of inhibitor-bound SMG1 kinase reveal an autoinhibitory state dependent on SMG8

    Lukas M Langer, Fabien Bonneau ... Elena Conti
    Structures of human SMG1-9 and SMG1-8-9 reveal how the SMG1 kinase active site is targeted by a specific inhibitor and provide insights into the regulation of the SMG1-8-9 kinase complex in nonsense-mediated mRNA decay.

    Purified EDEM3 or EDEM1 alone produces determinant oligosaccharide structures from M8B in mammalian glycoprotein ERAD

    Ginto George, Satoshi Ninagawa ... Kazutoshi Mori
    Biochemical analysis reveals the entire route of oligosaccharide processing from M9 to M8B and then to oligosaccharides exposing the α1,6-linked mannosyl residue (M7A, M6, and M5), and the enzymes (EDEM2 and EDEM3/1) responsible for endoplasmic reticulum-associated degradation of misfolded glycoproteins.

    Fusion of tethered membranes can be driven by Sec18/NSF and Sec17/αSNAP without HOPS

    Hongki Song, William T Wickner
    The coordinate activity of Sec17/SNAP and Sec18/NSF for membrane fusion is not limited to systems with homotypic fusion and vacuole protein sorting (HOPS), the lysosomal/vacuolar tethering, and SNARE assembly complex.

    All-trans retinoic acid induces synaptopodin-dependent metaplasticity in mouse dentate granule cells

    Maximilian Lenz, Amelie Eichler ... Andreas Vlachos
    All-trans retinoic acid increases the number of excitatory synapses in the dorsal hippocampus of mice and improves the ability of neurons to express synaptopodin-dependent synaptic plasticity.

    A functional genetic toolbox for human tissue-derived organoids

    Dawei Sun, Lewis Evans ... Emma L Rawlins
    To facilitate human developmental biology research, CRISPR-mediated homologous recombination, tightly inducible gene knockdowns (CRISPRi) and overexpression (CRISPRa) have been efficiently applied to human organoids.

    Pathogenic LRRK2 control of primary cilia and Hedgehog signaling in neurons and astrocytes of mouse brain

    Shahzad S Khan, Yuriko Sobu ... Suzanne R Pfeffer
    Striatal cholinergic interneurons and astrocytes lose cilia and show dysregulation of Hedgehog signaling in mice with a Parkinson's disease-associated, G2019S LRRK2 mutation or upon loss of PPM1H phosphatase specific for LRRK2-phosphorylated Rab GTPases.

    A MET-PTPRK kinase-phosphatase rheostat controls ZNRF3 and Wnt signaling

    Minseong Kim, Carmen Reinhard, Christof Niehrs
    HGF-MET signaling phosphorylates- and PTPRK dephosphorylates ZNRF3 to regulate ZNRF3 internalization, functioning as a rheostat for Wnt signaling.

    SARS-CoV-2 shedding dynamics across the respiratory tract, sex, and disease severity for adult and pediatric COVID-19

    Paul Z Chen, Niklas Bobrovitz ... Frank X Gu
    COVID-19 severity, rather than sex or age, predicts SARS-CoV-2 kinetics, and SARS-CoV-2 viral load from lower respiratory tract specimens may predict severe disease days before clinical deterioration for COVID-19 patients.

    microRNA-mediated regulation of microRNA machinery controls cell fate decisions

    Qiuying Liu, Mariah K Novak ... Wenqian Hu
    Genetic and biochemical analyses reveal that two stem-cell-specific microRNAs control stem cell fate decisions between pluripotency and differentiation through repressing Ago2, a key component of the microRNA machinery.
