    ER-luminal [Ca2+] regulation of InsP3 receptor gating mediated by an ER-luminal peripheral Ca2+-binding protein

    Horia Vais et al.
    Calcium release from the endoplasmic reticulum through the IP3 receptor ion channel is strongly regulated by a calcium-binding protein in the lumen of the endoplasmic reticulum.

    A new protocol for single-cell RNA-seq reveals stochastic gene expression during lag phase in budding yeast

    Abbas Jariani et al.
    A new high-throughput method for single-cell RNA-seq in yeast cells shows how stochastic expression of glucose-repressed genes contributes to cell-to-cell differences during adaptation to an environmental change.

    Bmal1 integrates mitochondrial metabolism and macrophage activation

    Ryan K Alexander et al.
    Macrophage Bmal1 controls the timing of the glycolytic to oxidative metabolism transition that dictates the extent of Hif-1a activation and the associated inflammatory response.

    Distinct mitochondrial defects trigger the integrated stress response depending on the metabolic state of the cell

    Eran Mick et al.
    Mitochondrial electron transport chain dysfunction triggers the integrated stress response due to an asparagine deficiency downstream of impaired NADH oxidation in proliferating myoblasts, but not in differentiated myotubes.

    Asymmetric clustering of centrosomes defines the early evolution of tetraploid cells

    Nicolaas C Baudoin et al.
    Newly formed tetraploid cells rapidly lose extra centrosomes acquired upon tetraploidization via asymmetric centrosome clustering during cell division and selective advantage of tetraploid daughter cells that inherit a single centrosome.

    Linker histone H1.2 and H1.4 affect the neutrophil lineage determination

    Gabriel Sollberger et al.
    Linker histones affect the lineage determination of granulocyte precursor cells via regulation of the transcription factor GATA-2.

    Opposing p53 and mTOR/AKT promote an in vivo switch from apoptosis to senescence upon telomere shortening in zebrafish

    Mounir El Maï et al.
    Telomere shortening with age promotes a switch from p53-dependent apoptosis to senescence prompted by tissue damage that triggers conflicting mTOR/AKT signalling, lower OxPhos defences and ROS, mitochondria dysfunction and senescence.

    A helminth-derived suppressor of ST2 blocks allergic responses

    Francesco Vacca et al.
    HpBARI is a protein secreted by a parasitic helminth, which binds to and blocks the IL-33 receptor, suppressing IL-33-dependent type 2 immune responses.

    A highly accurate platform for clone-specific mutation discovery enables the study of active mutational processes

    Mohammad KaramiNejadRanjbar et al.
    A robust library preparation and variant calling strategy (DigiPico/MutLX) eliminates false positive single nucleotide variants from picogram quantities of DNA following whole genome amplification.
