    Identification of human TERT elements necessary for telomerase recruitment to telomeres

    Jens C Schmidt et al.
    The TEN-domain of human telomerase mediates the direct interaction with TPP1 to drive telomerase recruitment to telomeres.

    The role of Rif1 in telomere length regulation is separable from its role in origin firing

    Calla B Shubin, Carol W Greider
    Telomere length is linked to DNA replication, and we found excessive telomeric origin firing caused by several distinct mutants did not lengthen telomeres, narrowing possible mechanisms.

    Telomere dysfunction cooperates with epigenetic alterations to impair murine embryonic stem cell fate commitment

    Mélanie Criqui et al.
    Cell lineage tracing and biochemical analysis of cell fate during murine stem cell differentiation demonstrates a specific cooperativity between perturbations in histone methylation and eroded telomeres that destabilize cell differentiation.

    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.

    Minimized human telomerase maintains telomeres and resolves endogenous roles of H/ACA proteins, TCAB1, and Cajal bodies

    Jacob M Vogan et al.
    The Cajal body chaperone TCAB1 and scaffold protein Coilin are not required for telomerase activity in human cells.

    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.

    Cancer-associated TERT promoter mutations abrogate telomerase silencing

    Kunitoshi Chiba et al.
    TERT promoter mutations impair TERT silencing upon cellular differentiation and are sufficient to facilitate cellular immortalization without additional tumor selected changes, explaining why they are associated with a very specific tumor spectrum.

    Persistent epigenetic memory impedes rescue of the telomeric phenotype in human ICF iPSCs following DNMT3B correction

    Shir Toubiana et al.
    Correction of the DNA methyltransferase 3B gene in ICF1 syndrome fails to rescue the abnormal DNA hypomethylation at subtelomeric regions due to accompanied epigenetic abnormalities in these regions.
