    Tumor suppressive role of sestrin2 during colitis and colon carcinogenesis

    Seung-Hyun Ro, Xiang Xue ... Jun Hee Lee
    Sestrin2 loss could be a universal mechanism of human colon carcinogenesis that allows for barrier dysfunction, mTORC1 hyperactivation, unrestricted tumor growth and chemoresistance.

    The Rqc2/Tae2 subunit of the ribosome-associated quality control (RQC) complex marks ribosome-stalled nascent polypeptide chains for aggregation

    Ryo Yonashiro, Erich B Tahara ... Claudio AP Joazeiro
    Rqc2-mediated modification of ribosome-stalled nascent chains with "CAT tails" promotes formation of insoluble aggregates suggesting that proteins can become specifically marked for aggregation.

    The MAP kinase pathway coordinates crossover designation with disassembly of synaptonemal complex proteins during meiosis

    Saravanapriah Nadarajan, Firaz Mohideen ... Monica P Colaiacovo
    Coordination between crossover designation and synaptonemal complex disassembly is executed via a conserved MAP kinase pathway and is critical for accurate chromosome segregation during meiosis.

    Waves of actin and microtubule polymerization drive microtubule-based transport and neurite growth before single axon formation

    Amy M Winans, Sean R Collins, Tobias Meyer
    Waves of polymerizing actin work in concert with microtubule polymerization to lay down more microtubules tracks and transiently increase microtubule-based transport into the growing neurite.

    Bistability of a coupled Aurora B kinase-phosphatase system in cell division

    Anatoly V Zaytsev, Dario Segura-Peña ... Ekaterina L Grishchuk
    Self-activating Aurora B kinase, opposed by an inhibitory phosphatase, forms spatial phosphorylation patterns during cell division.

    Non-canonical Wnt signalling modulates the endothelial shear stress flow sensor in vascular remodelling

    Claudio A Franco, Martin L Jones ... Holger Gerhardt
    A threshold level of blood flow initiates developmental blood vessel regression; this threshold can be regulated by non-canonical Wnt ligands.

    Aurkb/PP1-mediated resetting of Oct4 during the cell cycle determines the identity of embryonic stem cells

    Jihoon Shin, Tae Wan Kim ... Hong-Duk Youn
    The regulation of the core transcription factor Oct4 by the Aurkb-PP1 axis links the cell cycle to pluripotency programs in embryonic stem cells.

    Excitatory transmission onto AgRP neurons is regulated by cJun NH2-terminal kinase 3 in response to metabolic stress

    Santiago Vernia, Caroline Morel ... Roger J Davis
    Metabolic stress-induced activation of the JNK3 protein regulates excitatory transmission onto AgRP neurons to regulate food consumption.

    No current evidence for widespread dosage compensation in S. cerevisiae

    Eduardo M Torres, Michael Springer, Angelika Amon
    Dosage compensation does not take place in wild yeast strains.

    Rho-associated kinase (ROCK) function is essential for cell cycle progression, senescence and tumorigenesis

    Sandra Kümper, Faraz K Mardakheh ... Christopher J Marshall
    The Rho kinases ROCK1 and 2 act redundantly in regulating cell proliferation and their depletion causes cellular senescence.
