    Telomeric double-strand DNA-binding proteins DTN-1 and DTN-2 ensure germline immortality in Caenorhabditis elegans

    Io Yamamoto et al.
    The discovery of non-canonical telomeric dsDNA-binding proteins in Caenorhabditis elegans reveal their contribution in the maintenance of telomere length and germline immortality.

    Adaptive evolution of an essential telomere protein restricts telomeric retrotransposons

    Bastien Saint-Leandre et al.
    Evolution strictly preserves telomere stability but rapidly diversifies telomere length regulation in Drosophila.

    Mapping replication dynamics in Trypanosoma brucei reveals a link with telomere transcription and antigenic variation

    Rebecca Devlin et al.
    Mapping DNA replication timing, allied to genetic analysis of a RecQ repair helicase, reveals that antigenic variation in the African trypanosome may be initiated by locus-specific, replication-derived sequence instability.

    Expression site attenuation mechanistically links antigenic variation and development in Trypanosoma brucei

    Christopher Batram et al.
    The VSG gene controls its monoallelic expression, and expression site activity determines developmental progression.

    Mechanisms of nucleotide selection by telomerase

    Matthew A Schaich et al.
    The roles of key telomerase active site residues were elucidated to determine how telomerase selects the correct from the incorrect nucleotide to maintain telomere integrity.

    Kinesin Kif2C in regulation of DNA double strand break dynamics and repair

    Songli Zhu et al.
    Kinesin Kif2C is recruited to DNA damage sites, modulates the mobility and dynamics of DNA damage foci, and promotes DNA double strand break repair.

    Opposing p53 and mTOR/AKT promote an in vivo switch from apoptosis to senescence upon telomere shortening in zebrafish

    Mounir El Maï et al.
    Telomere shortening with age promotes a switch from p53-dependent apoptosis to senescence prompted by tissue damage that triggers conflicting mTOR/AKT signalling, lower OxPhos defences and ROS, mitochondria dysfunction and senescence.

    Telomeres: Getting to grips with circular chromosomes

    Constance Nugent, Katsunori Sugimoto
    A strain of budding yeast that contains one large chromosome reveals how the telomere capping complex CST maintains linear but not circular chromosomes.

    TINF2 is a haploinsufficient tumor suppressor that limits telomere length

    Isabelle Schmutz et al.
    Mutations in TIN2, a component of shelterin that keeps telomere length in check, lead to cancer-predisposition by disabling the telomere tumor suppressor pathway.
