Telomerase gene therapy in adult and old mice delays aging and increases longevity without increasing cancer

open access: yesEMBO Molecular Medicine, 2012
A major goal in aging research is to improve health during aging. In the case of mice, genetic manipulations that shorten or lengthen telomeres result, respectively, in decreased or increased longevity.

A telomerase holoenzyme protein enhances telomerase RNA assembly with telomerase reverse transcriptase [PDF]

open access: yesNature Structural & Molecular Biology, 2005
Telomerase maintains the simple sequence repeats at chromosome ends, protecting cells from genomic rearrangement, proliferative senescence and death. The telomerase reverse transcriptase (TERT) and telomerase RNA (TER) alone can assemble into active enzyme in a heterologous cell extract, but the physiological process of telomerase biogenesis is more ...

Dysregulation of H/ACA ribonucleoprotein components in chronic lymphocytic leukemia [PDF]

open access: yes, 2017
Telomeres are protective repeats of TTAGGG sequences located at the end of human chromosomes. They are essential to maintain chromosomal integrity and genome stability.

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

open access: yeseLife, 2018
Pulmonary fibrosis is a fatal lung disease characterized by fibrotic foci and inflammatory infiltrates. Short telomeres can impair tissue regeneration and are found both in hereditary and sporadic cases. We show here that telomerase expression using AAV9

Emerging roles of telomeric chromatin alterations in cancer [PDF]

open access: yes, 2019
Telomeres, the nucleoprotein structures that cap the ends of eukaryotic chromosomes, play important and multiple roles in tumorigenesis. Functional telomeres need the establishment of a protective chromatin structure based on the interplay between the ...

SIRT1 Is Necessary for Proficient Telomere Elongation and Genomic Stability of Induced Pluripotent Stem Cells

open access: yesStem Cell Reports, 2014
The NAD-dependent deacetylase SIRT1 is involved in chromatin silencing and genome stability. Elevated SIRT1 levels in embryonic stem cells also suggest a role for SIRT1 in pluripotency.

NMI inhibits cancer stem cell traits by downregulating hTERT in breast cancer. [PDF]

open access: yes, 2017
N-myc and STAT interactor (NMI) has been proved to bind to different transcription factors to regulate a variety of signaling mechanisms including DNA damage, cell cycle and epithelial-mesenchymal transition. However, the role of NMI in the regulation of

The N Terminus of the OB Domain of Telomere Protein TPP1 Is Critical for Telomerase Action

open access: yesCell Reports, 2018
Summary: Telomerase recruitment to telomeres and enzymatic processivity are mediated by TPP1, an essential component of telomere integrity and telomerase function.

How Structural Features Define Biogenesis and Function of Human Telomerase RNA Primary Transcript

open access: yesBiomedicines, 2022
Telomerase RNA has been uncovered as a component of the telomerase enzyme, which acts as a reverse transcriptase and maintains the length of telomeres in proliferated eukaryotic cells.

Mammalian telomeres and their partnership with lamins [PDF]

open access: yes, 2016
Chromosome ends are complex structures, which require a panel of factors for their elongation, replication, and protection. We describe here the mechanics of mammalian telomeres, dynamics and maintainance in relation to lamins.
