    Dynamic regulation of chromatin accessibility by pluripotency transcription factors across the cell cycle

    Elias T Friman, Cédric Deluz ... David M Suter
    OCT4 and SOX2 display partially independent activity to regulate chromatin accessibility, and highly dynamic activity of OCT4 is required throughout the cell cycle to maintain pluripotency enhancer accessibility.

    Paradoxical neuronal hyperexcitability in a mouse model of mitochondrial pyruvate import deficiency

    Andres De La Rossa, Marine H Laporte ... Jean-Claude Martinou
    Glutamatergic neurons lacking the mitochondrial pyruvate carrier show reduced M-type potassium channel activity and hyperexcitability upon intense firing.

    Metabolic requirement for GOT2 in pancreatic cancer depends on environmental context

    Samuel A Kerk, Lin Lin ... Costas A Lyssiotis
    Inhibition of GOT2 drives growth inhibitory reductive stress that can be rescued by electron acceptors in vitro, whereas GOT2 inhibition in endogenous or transplanted tumor models is tolerated without consequence, highlighting the importance of context when studying tumor metabolism.

    YAP/TAZ initiate and maintain Schwann cell myelination

    Matthew Grove, Hyukmin Kim ... Young-Jin Son
    Yap and Taz regulate proliferation and differentiation of Schwann cells, driving radial sorting, myelination and myelin maintenance of peripheral nerves.

    Hippocampal low-frequency stimulation prevents seizure generation in a mouse model of mesial temporal lobe epilepsy

    Enya Paschen, Claudio Elgueta ... Carola A Haas
    Optogenetic and electrical low-frequency stimulation in the sclerotic hippocampus prevents the emergence of spontaneous focal and evoked generalized seizures in a mouse epilepsy model.

    Single-cell transcriptomics reveals a new dynamical function of transcription factors during embryonic hematopoiesis

    Isabelle Bergiers, Tallulah Andrews ... Christophe Lancrin
    Single-cell transcriptomics analysis identifies the dynamic activity of transcription factors at the onset of hematopoeitic stem and progenitor cells formation during embryonic development.

    Phenotypic plasticity underlies local invasion and distant metastasis in colon cancer

    Andrea Sacchetti, Miriam Teeuwssen ... Riccardo Fodde
    Colon cancer cells disseminate and colonize distant organ sites along the invasion-metastasis cascade by transiently activating intermediate epithelial to mesenchymal transition states through distinct transcriptional trajectories.

    Identifying gene expression programs of cell-type identity and cellular activity with single-cell RNA-Seq

    Dylan Kotliar, Adrian Veres ... Pardis C Sabeti
    A novel algorithm, consensus non-negative matrix factorization (cNMF), accurately identifies gene expression programs underlying cell-type identity and cellular activities from single-cell RNA-Seq data.

    Mouse B2 SINE elements function as IFN-inducible enhancers

    Isabella Horton, Conor J Kelly ... Edward B Chuong
    An epigenomic analysis in mouse macrophages reveals that a highly abundant transposable element exhibits activity as an immune inducible regulatory element.
