    PLZF targets developmental enhancers for activation during osteogenic differentiation of human mesenchymal stem cells

    Shuchi Agrawal Singh et al.
    A key transcription-factor for osteogenic differentiation, PLZF, acts as a transcriptional activator by binding to active developmental enhancers and facilitates mediator recruitment, but is not involved in enhancer looping.

    A single regulator NrtR controls bacterial NAD+ homeostasis via its acetylation

    Rongsui Gao et al.
    Functional definition of NrtR and the discovery of its acetylation represents a first paradigm for linking protein acetylation to bacterial central NAD+ metabolism.

    A positive feedback loop between Myc and aerobic glycolysis sustains tumor growth in a Drosophila tumor model

    Kenneth Kin Lam Wong et al.
    Specific molecular links that orchestrate growth signals and metabolic reprogramming to achieve tumorigenesis are identified as potential metabolic vulnerabilities in cancer treatment.

    Dual control of NAD+ synthesis by purine metabolites in yeast

    Benoît Pinson et al.
    Two distinct processes drive coordinated synthesis of purine and pyridine (NAD+) nucleotides in response to AICAR derivatives and ATP.

    Insulin mutations impair beta-cell development in a patient-derived iPSC model of neonatal diabetes

    Diego Balboa et al.
    Mutations causing proinsulin misfolding trigger unfolded protein response and lead to impaired proliferation and reduced mTORC1 signalling of developing beta-cells in a patient-derived induced pluripotent stem cell disease model.

    Temporal profiling of redox-dependent heterogeneity in single cells

    Meytal Radzinski et al.
    Analysis of aging yeast cells using the in-vivo roGFP2-based probe reveals redox-dependent heterogeneity, reflected in a bi-modal distribution of the oxidation status, differential growth and replication, as well as distinct proteomic and transcriptomic profiles.

    Elastic force restricts growth of the murine utricle

    Ksenia Gnedeva et al.
    Computational modeling and molecular-biological analysis reveal the role of mechanical force and downstream Yap signaling in growth control during the development and regeneration of sensory epithelium of the inner ear.

    Tumors attenuating the mitochondrial activity in T cells escape from PD-1 blockade therapy

    Alok Kumar et al.
    Downregulation of mitochondrial activity by immunosuppressive tumor-derived soluble factors leads to systemic unresponsiveness to the PD-1 blockade therapy.

    Super Spy variants implicate flexibility in chaperone action

    Shu Quan et al.
    Lab-evolved 'super Spy' chaperones show enhanced flexibility, which allows them to bind to and stabilize proteins more effectively than natural chaperones.

    Transient rapamycin treatment can increase lifespan and healthspan in middle-aged mice

    Alessandro Bitto et al.
    Three months treatment with the drug rapamycin increases lifespan, alters cancer prevalence, remodels the microbiome, and improves functional measures of health in middle aged mice in a dose- and sex-dependent manner.
