Exercise training increases telomerase reverse transcriptase gene expression and telomerase activity: A systematic review and meta-analysis

open access: yes, 2021
Telomeres protect genomic stability and shortening is one of the hallmarks of ageing. Telomerase reverse transcriptase (TERT) is the major protein component of telomerase, which elongates telomeres.

A DNA G‐Quadruplex‐Targeting Ligand Suppresses c‐MYC Expression: Implications for Gemcitabine‑Resistant Pancreatic Cancer

open access: yesAngewandte Chemie, EarlyView.
PQB‐4, a fluorescent small‐molecule ligand that targets c‐MYC DNA G‐quadruplexes (G4s), showed marked synergy with gemcitabine in resistant PANC‐1 cells (CI = 0.027). In vivo, the ligand reduced tumor weight by 44% in a PANC‐1 xenograft model. These results highlight the therapeutic potential of c‐MYC DNA G4‐targeting ligands for treating gemcitabine ...

Ancestral mutation in telomerase causes defects in repeat addition processivity and manifests as familial pulmonary fibrosis. [PDF]

open access: yesPLoS Genetics, 2011
The telomerase reverse transcriptase synthesizes new telomeres onto chromosome ends by copying from a short template within its integral RNA component. During telomere synthesis, telomerase adds multiple short DNA repeats successively, a property known ...

Pof8 is a La-related protein and a constitutive component of telomerase in fission yeast

open access: yesNature Communications, 2018
The core of the telomerase holoenzyme is composed of the reverse transcriptase and the non-coding RNA template. Here the authors identify Pof8 as a new constitutive component of fission yeast telomerase, loss of which causes telomerase assembly defects ...

Abnormal telomere shortening of peripheral blood mononuclear cells and granulocytes in patients with chronic idiopathic neutropenia

open access: yesHaematologica, 2012
Background Chronic idiopathic neutropenia is characterized by immune-mediated suppression of neutrophil production. Because patients with immune-mediated bone marrow failure syndromes display age-inappropriate telomere shortening in leukocytes, we ...

Telomerase and retrotransposons: Reverse transcriptases that shaped genomes [PDF]

open access: yesProceedings of the National Academy of Sciences, 2011
“Two independent groups of investigators have found evidence of an enzyme… which synthesizes DNA from an RNA template. This discovery, if upheld, will have important implications… information transfer from DNA to RNA can be inverted.” 1970, preamble to refs. 1 and 2.

Telomerase in Brain: The New Kid on the Block and Its Role in Neurodegenerative Diseases

open access: yesBiomedicines, 2021
Telomerase is an enzyme that in its canonical function extends and maintains telomeres, the ends of chromosomes. This reverse transcriptase function is mainly important for dividing cells that shorten their telomeres continuously.

Telomere erosion in memory T cells induced by telomerase inhibition at the site of antigenic challenge in vivo. [PDF]

open access: yes, 2004
The extent of human memory T cell proliferation, differentiation, and telomere erosion that occurs after a single episode of immune challenge in vivo is unclear.

LARP7 family proteins have conserved function in telomerase assembly

open access: yesNature Communications, 2018
The telomerase holoenzyme is minimally composed of the reverse transcriptase and the RNA template. Here the authors identify Lar7 as a member of the full complex that helps to stabilise it and protect telomerase RNA from degradation.

Fine-mapping identifies multiple prostate cancer risk loci at 5p15, one of which associates with TERT expression [PDF]

open access: yes, 2013
Associations between single nucleotide polymorphisms (SNPs) at 5p15 and multiple cancer types have been reported. We have previously shown evidence for a strong association between prostate cancer (PrCa) risk and rs2242652 at 5p15, intronic in the ...
