    Architecture of the chromatin remodeler RSC and insights into its nucleosome engagement

    Avinash B Patel et al.
    The structure of the yeast RSC complex, a member of the SWI/SNF chromatin remodeling family, determined by cryo-electron microscopy, reveals a conserved structural core and the mode of nucleosome engagement.

    HSF-1 activates the ubiquitin proteasome system to promote non-apoptotic developmental cell death in C. elegans

    Maxime J Kinet et al.
    A pathway controlling non-apoptotic developmental cell death engages non-canonical death-promoting activities of the stress factor HSF-1, which, in turn, activates specific components of the ubiquitin-mediated degradation machinery.

    Histone demethylase Lsd1 represses hematopoietic stem and progenitor cell signatures during blood cell maturation

    Marc A Kerenyi et al.
    Lysine-specific demethylase 1 (Lsd1) has an essential role during both the early and later stages of blood cell development.

    Rab5 and Alsin regulate stress-activated cytoprotective signaling on mitochondria

    FoSheng Hsu et al.
    Oxidative stress leads to the translocation of Rab5 from endosome to mitochondria, regulated by ALS/Alsin, a component associated with amyotrophic lateral sclerosis, leading to mitochondrial-endosomal physical contacts and a cytoprotective response.

    A human ESC-based screen identifies a role for the translated lncRNA LINC00261 in pancreatic endocrine differentiation

    Bjoern Gaertner et al.
    Ribosome profiling and loss-of-function during human ESC pancreatic differentiation reveal abundant lncRNA translation and an essential role for translated LINC00261 in beta cell differentiation, likely through a trans-regulatory, microprotein-independent mechanism.

    Murine HSCs contribute actively to native hematopoiesis but with reduced differentiation capacity upon aging

    Petter Säwen et al.
    Using a lineage tracing model, it is demonstrated that adult murine hematopoiesis is contingent on the continuous output from HSCs, with quantitative contributions that are dependent on lineage-type and age.

    Structural basis for human TRPC5 channel inhibition by two distinct inhibitors

    Kangcheng Song et al.
    The binding sites of two distinct TRPC5 inhibitors clemizole and HC-070 are revealed by cryo-EM.

    Dlk1-Dio3 locus-derived lncRNAs perpetuate postmitotic motor neuron cell fate and subtype identity

    Ya-Ping Yen et al.
    LncRNAs are important to stabilize postmitotic cell fate of spinal motor neurons.

    Human perivascular stem cell-derived extracellular vesicles mediate bone repair

    Jiajia Xu et al.
    Perivascular extracellular vesicles induce bone repair, and do so via tetraspanin binding to recipient skeletal progenitor cells.

    Tumor suppressor SMARCB1 suppresses super-enhancers to govern hESC lineage determination

    Lee F Langer et al.
    The chromatin remodeler and tumor suppressor SMARCB1 acts to restrict superenhancer function to direct neural differentiation of embryonic stem cells while repressing bivalent gene activity in the pluripotent state.
