    The transcription factors TFE3 and TFEB amplify p53 dependent transcriptional programs in response to DNA damage

    Owen A Brady, Eutteum Jeong ... Rosa Puertollano
    Disruption of TFEB and TFE3 results in diminished p53 signaling capacity and altered cell cycle regulation under genotoxic stress conditions.

    The sterol-responsive RNF145 E3 ubiquitin ligase mediates the degradation of HMG-CoA reductase together with gp78 and Hrd1

    Sam A Menzies, Norbert Volkmar ... Paul J Lehner
    CRISPR/Cas9 genome-wide screens using sterol-sensitive endogenous HMG-CoA reductase (HMGCR) reporter identify the sterol-responsive RNF145 and gp78 as independently responsible for sterol-accelerated degradation of HMGCR, the rate-limiting enzyme of cholesterol biosynthesis.

    Splicing factors Sf3A2 and Prp31 have direct roles in mitotic chromosome segregation

    Claudia Pellacani, Elisabetta Bucciarelli ... Maria Patrizia Somma
    Extensive cytological and biochemical analyses show that the conserved Sf3A2 and Prp31 splicing factors bind microtubules and the Ndc80 complex, playing direct mitotic functions in both Drosophila and human mitosis.

    Lipidation-independent vacuolar functions of Atg8 rely on its noncanonical interaction with a vacuole membrane protein

    Xiao-Man Liu, Akinori Yamasaki ... Li-Lin Du
    The core autophagy protein Atg8 plays non-autophagy roles through binding to an integral membrane protein Hfl1, which harbors an unusual Atg8-interacting motif.

    Membrane fluidity is regulated by the C. elegans transmembrane protein FLD-1 and its human homologs TLCD1/2

    Mario Ruiz, Rakesh Bodhicharla ... Marc Pilon
    Inhibition of C. elegans FLD-1 or Human TLCD1/2 prevents saturated fat lipotoxicity by allowing increased levels of membrane phospholipids that contain fluidizing long-chain polyunsaturated fatty acids.

    Endothelial-specific FoxO1 depletion prevents obesity-related disorders by increasing vascular metabolism and growth

    Martina Rudnicki, Ghoncheh Abdifarkosh ... Tara L Haas
    Stimulation of endothelial glucose metabolism and vascular growth by genetic depletion of endothelial Foxo1 improves the whole-body response to a high-fat diet, by preserving adipose tissue functions and glucose homeostasis.

    The insulin/IGF signaling cascade modulates SUMOylation to regulate aging and proteostasis in Caenorhabditis elegans

    Lorna Moll, Noa Roitenberg ... Ehud Cohen
    By controlling the SUMOylation of the protein CAR-1, the aging-regulating pathways downstream of the Insulin/IGF signaling cascade and of the germ cells of the nematode Caenorhabditis elegans are integrated.

    Global transcriptional analysis identifies a novel role for SOX4 in tumor-induced angiogenesis

    Stephin J Vervoort, Olivier G de Jong ... Paul J Coffer
    Global transcriptome analysis reveals that the transcription factor SOX4 can promote breast tumor development via tumor angiogenesis by promoting paracrine signalling through endothelin-1.

    Comment on ‘Orthogonal lipid sensors identify transbilayer asymmetry of plasma membrane cholesterol’

    Kevin C Courtney, Karen YY Fung ... Xiaohui Zha
    We challenge a recent report that most of the cholesterol in the plasma membrane of mammalian cells is in the exofacial leaflet.
