    Telomere repeats induce domains of H3K27 methylation in Neurospora

    Kirsty Jamieson et al.
    Vast regions of facultative heterochromatin marked by methylation of lysine 27 on histone H3 depend on their proximity to chromosome ends and can be induced ectopically by insertion of telomere repeats.

    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.

    The RNA interactome of human telomerase RNA reveals a coding-independent role for a histone mRNA in telomere homeostasis

    Roland Ivanyi-Nagy et al.
    A messenger RNA coding for the histone 1.2 protein negatively regulates telomere elongation by interacting with human telomerase RNA.

    Single-molecule imaging of telomerase reverse transcriptase in human telomerase holoenzyme and minimal RNP complexes

    Robert Alexander Wu et al.
    New labeling approaches for single-molecule fluorescence microscopy detect the monomeric catalytic subunit of human telomerase within cellular holoenzyme and minimal active recombinant enzyme.

    A sharp Pif1-dependent threshold separates DNA double-strand breaks from critically short telomeres

    Jonathan Strecker et al.
    A sharp transition in the fate of DNA ends with telomere sequences is identified, which suggests a boundary between DNA double-strand breaks and telomeres.

    TERRA regulate the transcriptional landscape of pluripotent cells through TRF1-dependent recruitment of PRC2

    Rosa María Marión et al.
    Telomeric TRF1 controls the transcriptional programmes of pluripotent stem cells by recruiting PRC2 to pluripotency and differentiation genes by controlling the expression of those gene sites and the binding of TERRA RNAs to them.

    Longitudinal trajectories, correlations and mortality associations of nine biological ages across 20-years follow-up

    Xia Li et al.
    Biological ages have the potential to provide aging-related information beyond chronological age and can be predictive of mortality independently of both chronological age and different types of biological ages.

    Structure of the germline genome of Tetrahymena thermophila and relationship to the massively rearranged somatic genome

    Eileen P Hamilton et al.
    The model organism Tetrahymena thermopile carries two nuclei with distinct genomes: an unrearranged germline genome with five chromosomes, and a somatic genome reduced in size by a third and with 181 chromosomes.

    ASH1-catalyzed H3K36 methylation drives gene repression and marks H3K27me2/3-competent chromatin

    Vincent T Bicocca et al.
    While SET-2 methylates histone H3K36 during transcription, ASH1 methylates this residue in repressed regions, is important for silencing, and can both positively and negatively influence methylation of histone H3K27.

    The Ku subunit of telomerase binds Sir4 to recruit telomerase to lengthen telomeres in S. cerevisiae

    Evan P Hass, David C Zappulla
    In yeast, the secondary pathway for recruiting telomerase to chromosome ends requires a component of telomeric transcriptionally silent chromatin.
