    The nucleolar protein NIFK promotes cancer progression via CK1α/β-catenin in metastasis and Ki-67-dependent cell proliferation

    Tsung-Chieh Lin et al.
    NIFK promotes lung cancer metastasis via Runx1-dependent repression of CK1α, which activates TCF4/β-catenin signaling.

    Atomic model of the F420-reducing [NiFe] hydrogenase by electron cryo-microscopy using a direct electron detector

    Matteo Allegretti et al.
    The structure of a large enzyme complex involved in methanogenesis was determined at high resolution by electron cryo-microscopy.

    Hepatic NF-kB-inducing kinase (NIK) suppresses mouse liver regeneration in acute and chronic liver diseases

    Yi Xiong et al.
    Genetic mouse models show that hepatic NIK and IKKα inhibit hepatocyte proliferation and liver regeneration in part by inhibiting the JAK2/STAT3 pathway.

    Human RPA activates BLM’s bidirectional DNA unwinding from a nick

    Zhenheng Qin et al.
    hRPA permits the BLM helicase to bidirectionally unwind DNA from a nick which could potentially facilitate its function switching in DNA repair and promote end resection in homologous recombination.

    De novo modeling of the F420-reducing [NiFe]-hydrogenase from a methanogenic archaeon by cryo-electron microscopy

    Deryck J Mills et al.
    The structure of a large hydrogenase complex involved in the production of methane by microbes has been determined with cryo-electron microscopy.

    Stochasticity in the miR-9/Hes1 oscillatory network can account for clonal heterogeneity in the timing of differentiation

    Nick E Phillips et al.
    Stochasticity introduced computationally into a gene expression oscillator creates heterogeneity in the time of differentiation of identical cells and offers robustness to the progenitor state and the outcome of cell division.

    Mechanisms of iron- and O2-sensing by the [4Fe-4S] cluster of the global iron regulator RirA

    Ma Teresa Pellicer Martinez et al.
    Molecular details of how the iron–sulfur cluster cofactor of a bacterial global iron regulatory protein simultaneously senses iron and O2 are revealed by mass spectrometry and spectroscopy.

    Effective control of SARS-CoV-2 transmission between healthcare workers during a period of diminished community prevalence of COVID-19

    Nick K Jones et al.
    Diminished incidence of COVID-19 amongst healthcare workers in a comprehensive screening programme demonstrates how effective infection control measures and staff testing can prevent hospitals becoming independent 'hubs' of SARS-CoV-2 transmission.

    The NFκB-inducing kinase is essential for the developmental programming of skin-resident and IL-17-producing γδ T cells

    Florian Mair et al.
    Thymic stromal cells help to develop and shape the gamma delta T cell pool.

    A bipartite iron-dependent transcriptional regulation of the tryptophan salvage pathway in Chlamydia trachomatis

    Nick D Pokorzynski et al.
    Analysis of the atypical tryptophan biosynthetic operon of Chlamydia trachomatis revealed the simultaneous regulation of transcriptional initiation and termination by an iron-dependent repressor, expanding known regulatory mechanisms of this pathway.
