    Mechanisms of nucleotide selection by telomerase

    Matthew A Schaich, Samantha L Sanford ... Bret D Freudenthal
    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.

    Therapeutic effects of telomerase in mice with pulmonary fibrosis induced by damage to the lungs and short telomeres

    Juan Manuel Povedano, Paula Martinez ... Maria A Blasco
    Telomerase gene therapy represents a novel effective treatment for pulmonary fibrosis associated with short telomeres by improving pulmonary function, decreasing inflammation and accelerating fiber disappearance in fibrotic lungs.

    TRF1 averts chromatin remodelling, recombination and replication dependent-break induced replication at mouse telomeres

    Rosa Maria Porreca, Emilia Herrera-Moyano ... Jean-Baptiste Vannier
    TRF1 suppresses replication fork stalling, which triggers break induced replication at telomeres associated with DNA damage response, alteration in the telomere chromatin environment, and re-localisation of telomeres to PML bodies.

    GSK3 inhibition rescues growth and telomere dysfunction in dyskeratosis congenita iPSC-derived type II alveolar epithelial cells

    Rafael Jesus Fernandez, Zachary JG Gardner ... F Brad Johnson
    Telomere dysfunction in iPSC-derived type II alveolar epithelial cells causes senescence and gene expression changes including Wnt-related changes that GSK3 inhibition can rescue, providing insight into pulmonary fibrosis pathogenesis.

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

    Roland Ivanyi-Nagy, Syed Moiz Ahmed ... Peter Dröge
    A messenger RNA coding for the histone 1.2 protein negatively regulates telomere elongation by interacting with human telomerase RNA.

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

    Jacob M Vogan, Xiaozhu Zhang ... Kathleen Collins
    The Cajal body chaperone TCAB1 and scaffold protein Coilin are not required for telomerase activity in human cells.

    Integrated evaluation of telomerase activation and telomere maintenance across cancer cell lines

    Kevin Hu, Mahmoud Ghandi, Franklin W Huang
    Comprehensive analysis of telomere maintenance from transcriptomic, epigenetic, and loss-of-function profiles of cancer cell lines elucidates features of telomere regulation in cancer.

    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.

    Multi-step coordination of telomerase recruitment in fission yeast through two coupled telomere-telomerase interfaces

    Xichan Hu, Jinqiang Liu ... Feng Qiao
    A telomerase recruitment mechanism delivers cell cycle information to the telomere-telomerase interface to ensure timely telomerase engagement at the telomere.
