    Molecular basis of force-from-lipids gating in the mechanosensitive channel MscS

    Bharat Reddy et al.
    The structure of the mechanosensitive channel MscS embedded in a lipid bilayer redefines the nature, location and importance of lipid–protein interactions in the gating of mechanosensitive channels.

    Chlamydia trachomatis-containing vacuole serves as deubiquitination platform to stabilize Mcl-1 and to interfere with host defense

    Annette Fischer et al.
    Obligate intracellular Chlamydia secrete a deubiquitinating enzyme (Cdu1) into the membrane of the Chlamydia-containing vacuole to deubiquitinate selected host proteins and support the survival of the bacteria during genital infection.

    Single molecule FRET reveals pore size and opening mechanism of a mechano-sensitive ion channel

    Yong Wang et al.
    Observation by single molecule FRET of MscL, a prokaryotic mechanosensitive channel, reveals that MscL opens via the helix-tilt model and its pore reaches 2.8 nm in diameter.

    New approach for membrane protein reconstitution into peptidiscs and basis for their adaptability to different proteins

    Gabriella Angiulli et al.
    Cryo-EM structures reveal how the peptidisc scaffold can adapt to different membrane proteins, establishing it as a universal membrane mimetic to stabilize membrane proteins in solution.

    MOF-associated complexes ensure stem cell identity and Xist repression

    Tomasz Chelmicki et al.
    Two complexes that contain the histone acetyl transferase MOF engage in a two-pronged approach to ensure the repression of X inactivation in mouse embryonic stem cells.

    Mof-associated complexes have overlapping and unique roles in regulating pluripotency in embryonic stem cells and during differentiation

    Sarina Ravens et al.
    Two complexes that contain the histone acetyl transferase MOF have distinct regulatory roles in the growth and development of pluripotent embryonic stem cells

    Mesenchymal stromal cell aging impairs the self-organizing capacity of lung alveolar epithelial stem cells

    Diptiman Chanda et al.
    Lung stem cell niche aging is associated with altered bioenergetics, metabolic dysfunction, and senescence of mesenchymal stromal cells that restricts 3D organoid, or alveolosphere formation, potentially accounting for reduced regenerative capacity with aging.

    Activation of hedgehog signaling in mesenchymal stem cells induces cartilage and bone tumor formation via Wnt/β-Catenin

    Qi Deng et al.
    Cartilage and bone tumors arise from chondrocyte or osteoblast progenitors but not differentiated cells or multipotent mesenchymal stem cells (MSCs) via the IHH-Wnt/β-Catenin pathway.

    Epstein-Barr virus ensures B cell survival by uniquely modulating apoptosis at early and late times after infection

    Alexander M Price et al.
    Epstein-Barr virus hijacks host anti-apoptotic machinery to ensure survival during latent infection.

    Biological constraints on GWAS SNPs at suggestive significance thresholds reveal additional BMI loci

    Reza K Hammond et al.
    By integrating GWAS data sets with ATAC-seq and promoter-focused Capture C data, one can uncover further loci beyond those that reach genome-wide significance (p<5x10-8).
