    Histone H1 prevents non-CG methylation-mediated small RNA biogenesis in Arabidopsis heterochromatin

    Jaemyung Choi, David B Lyons, Daniel Zilberman
    Linker histone H1 and cytosine DNA methylation in contexts other than CG explain patterns of 24 nucleotide small RNA biogenesis in Arabidopsis thaliana.

    Structure of the human ATM kinase and mechanism of Nbs1 binding

    Christopher Warren, Nikola P Pavletich
    Structures of the human ataxia-telangiectasia mutated (ATM) kinase alone and bound to the C-terminus of Nbs1 show the mechanisms underlying ATM autoinhibition and binding by a portion of the Mre11-Rad50-Nbs1 (MRN) activating complex.

    Environmental selection overturns the decay relationship of soil prokaryotic community over geographic distance across grassland biotas

    Biao Zhang, Kai Xue ... Yanfen Wang
    Environmental selection overwhelmed the geographic 'distance' effect when across biotas, overturning the previously well-accepted geographic pattern for microbes on a large scale.

    RNA binding to human METTL3-METTL14 restricts N6-deoxyadenosine methylation of DNA in vitro

    Shan Qi, Javier Mota ... Yogesh K Gupta
    Structured RNA elements bind to the human methyltransferase like-3 (METTL3)-METTL14 enzyme complex with high affinity and restrict the formation of N6-deoxymethyladenosine in DNA.

    A helicase-tethered ORC flip enables bidirectional helicase loading

    Shalini Gupta, Larry J Friedman ... Stephen P Bell
    A single origin–recognition complex (ORC) directs loading of a pair of head-to-head Mcm2-7 replicative DNA helicases by forming a protein tether to the first helicase, releasing from its initial DNA-binding site, and rebinding the origin DNA in the opposite orientation.

    Covalent inhibition of endoplasmic reticulum chaperone GRP78 disconnects the transduction of ER stress signals to inflammation and lipid accumulation in diet-induced obese mice

    Dan Luo, Ni Fan ... Jianhui Rong
    Celastrol covalently inhibited the chaperone activity of GRP78 and could disconnect the transduction of ER stress signal to downstream inflammatory response and lipid metabolism.

    KIF2C regulates synaptic plasticity and cognition in mice through dynamic microtubule depolymerization

    Rui Zheng, Yonglan Du ... Junyu Xu
    KIF2C plays an important role in synaptic plasticity and cognition behaviors in mice by regulating activity-dependent microtubule dynamic.

    A zebrafish embryo screen utilizing gastrulation identifies the HTR2C inhibitor pizotifen as a suppressor of EMT-mediated metastasis

    Joji Nakayama, Lora Tan ... Zhiyuan Gong
    Zebrafish embryo screen utilizing conserved mechanisms between cancer metastasis and zebrafish gastrulation identifies the HTR2C inhibitor pizotifen as anti-metastasis drugs.

    Structural basis for cytoplasmic dynein-1 regulation by Lis1

    John P Gillies, Janice M Reimer ... Samara L Reck-Peterson
    A 3.1 Å structure of cytoplasmic dynein-1 in complex with its regulator Lis1 reveals the interfaces between dynein and Lis1, all of which are important for dynein function in vitro and in vivo.

    Impact of long- and short-range fibre depletion on the cognitive deficits of fronto-temporal dementia

    Melissa Savard, Tharick A Pascoal ... Pedro Rosa-Neto
    While semantic symptoms in fronto-temporal dementia patients were mainly dependent on short-range white-matter fibre disruption, long-range white-matter fibres damage was the major contributor to executive dysfunction, highlighting the importance of controlling for risk factors associated with deep white-matter disease.
