    BRAFV600E cooperates with CDX2 inactivation to promote serrated colorectal tumorigenesis

    Naoya Sakamoto et al.
    Genetic analyses reveal how CDX2 and BRAF defects seen in serrated colorectal cancer (CRCs), a poor prognosis CRC subset, cooperate in tumorigenesis in humans and in a mouse cancer model.

    T cell receptor repertoires of mice and humans are clustered in similarity networks around conserved public CDR3 sequences

    Asaf Madi et al.
    A new perception of the organization of T-cell receptor repertoires in mice and humans, based on high-throughput sequencing and CDR3 sequence similarity, indicates hubs of cross-species public sequences forming evolutionary conserved 'foci of attention' of T cell immunity.

    DDR2 controls breast tumor stiffness and metastasis by regulating integrin mediated mechanotransduction in CAFs

    Samantha VH Bayer et al.
    The action of the collagen receptor DDR2 in CAFs regulates Rap1-Talin1 mediated Integrin mechanotransduction in breast tumors to impact tumor stiffness and metastases.

    Cortical regulation of cell size by a sizer cdr2p

    Kally Z Pan et al.
    It is shown that fission yeast cells sense their size by measuring their surface area through a membrane-associated sizer protein cdr2p.

    Identification of Pol IV and RDR2-dependent precursors of 24 nt siRNAs guiding de novo DNA methylation in Arabidopsis

    Todd Blevins et al.
    The 24-nucleotide long siRNAs that guide cytosine methylation in Arabidopsis are made by dicing short double-stranded RNAs that are only around 30 nucleotides long.

    Cyclin-dependent kinase control of motile ciliogenesis

    Eszter K Vladar et al.
    Cyclin-dependentkinase 2 (Cdk2), the master regulator of S phase events during the cell cycle, controls the earliest step in the motile ciliogenesis pathway in quiescent multiciliatedairway epithelial cells.

    Centriolar satellites assemble centrosomal microcephaly proteins to recruit CDK2 and promote centriole duplication

    Andrew Kodani et al.
    To control centriole duplication, centriolar satellite proteins assemble a microcephaly-associated protein complex at the centrosome and activate cyclin-dependent kinase 2.

    An ultralong CDRH2 in HCV neutralizing antibody demonstrates structural plasticity of antibodies against E2 glycoprotein

    Andrew I Flyak et al.
    The crystal structure of neutralizing antibody AR3X in complex with HCV E2 glycoprotein reveals unusual features of antibody recognition in which a conserved epitope is recognized by distinct antibody poses.

    Rejuvenating conventional dendritic cells and T follicular helper cell formation after vaccination

    Marisa Stebegg et al.
    Older individuals have impaired conventional dendritic cell and T follicular helper cell formation upon vaccination, which can be rescued by treatment with a TLR7 agonist.

    Two distinct DNA sequences recognized by transcription factors represent enthalpy and entropy optima

    Ekaterina Morgunova et al.
    The epistasis observed in TF-DNA binding preferences can be explained by the presence of two optima of very similar Gibbs energy that are located relatively far from each other in sequence space.
