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 ...

Involvement of Telomerase Reverse Transcriptase in Heterochromatin Maintenance [PDF]

open access: yesMolecular and Cellular Biology, 2014
In the fission yeast Schizosaccharomyces pombe, centromeric heterochromatin is maintained by an RNA-directed RNA polymerase complex (RDRC) and the RNA-induced transcriptional silencing (RITS) complex in a manner that depends on the generation of short interfering RNA.

QSAR, pharmacophore modeling and molecular docking studies to identify structural alerts for some nitrogen heterocycles as dual inhibitor of telomerase reverse transcriptase and human telomeric G-quadruplex DNA

open access: yesFuture Journal of Pharmaceutical Sciences, 2021
Background Telomerase reverse transcriptase (TERT) and human telomeric G-quadruplex DNA are amongst the favorable target for researchers to discover novel and more effective anticancer agents.

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 ...

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 ...

Telomerase reverse transcriptase moonlights: Therapeutic targets beyond telomerase

open access: yesCancer Science, 2015
Telomeres, the repetitive sequences at chromosomal ends, protect intact chromosomes. Telomeres progressively shorten through successive rounds of cell divisions, and critically shortened telomeres trigger senescence and apoptosis. The enzyme that elongates telomeres and maintains their structure is known as telomerase.

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 ...

Implications of telomerase reverse transcriptase in tumor metastasis

open access: yesBMB Reports, 2020
Metastasis is the main culprit of the great majority of cancerrelated deaths. However, the complicated process of the invasion-metastasis cascade remains the least understood aspect of cancer biology. Telomerase plays a pivotal role in bypassing cellular senescence and sustaining the cancer progression by maintaining telomere homeostasis and genomic ...

There is no correlation between c-Myc mRNA expression and telomerase activity in human breast cancer

open access: yes, 2004
Background Telomerase is a ribonucleoprotein enzyme that synthesises telomeres after cell division and maintains chromosomal length and stability thus leading to cellular immortalisation.

MDM2 negatively regulates the human telomerase RNA gene promoter [PDF]

open access: yes, 2005
<b>Background:</b> We have previously demonstrated that NF-Y and Sp1 interact with the human telomerase RNA (hTR) promoter and play a central role in its regulation. We have also shown that pRB activates the hTR promoter, but the mechanism
