Oxidative stress, telomeres and cellular senescence: What non-drug interventions might break the link? [PDF]

open access: yes, 2020
Telomeres are higher order structures that cap and protect chromosome ends. Telomeric DNA naturally shortens during somatic cell division and as a result of oxidative stress.

AZT as a telomerase inhibitor

open access: yesFrontiers in Oncology, 2012
Telomerase is a highly specialized reverse transcriptase and the maintenance of telomeric length is determined by this specific enzyme. The human holoenzyme telomerase is a ribonucleoprotein composed by a catalytic subunit, hTERT, an RNA component, hTR ...

CDK1 dependent phosphorylation of hTERT contributes to cancer progression

open access: yesNature Communications, 2020
Regulated telomerase reverse transcriptase (hTERT) activity is common in human tumors. Here, the authors show that hTERT is phosphorylated by CDK1 and that this event is necessary for hTERT-mediated RNA dependent RNA polymerase activity but not for ...

Is telomerase reactivation associated with the down-regulatoin of TGFβ receptor-II expression in human breast cancer? [PDF]

open access: yes, 2003
Background Telomerase is a ribonucleoprotein that synthesizes telomeres and plays an important role in chromosomal stability and cellular immortalisation. Telomerase activity is detectable in most human cancers but not in normal somatic cells. TGF beta (

Insertion of retrotransposons at chromosome ends: adaptive response to chromosome maintenance

open access: yesFrontiers in Genetics, 2016
The telomerase complex is a specialized reverse transcriptase that inserts tandem DNA arrays at the linear chromosome ends and contributes to the protection of the genetic information in eukaryotic genomes.

Cancer-associated TERT promoter mutations abrogate telomerase silencing. [PDF]

open access: yes, 2015
Mutations in the human telomerase reverse transcriptase (TERT) promoter are the most frequent non-coding mutations in cancer, but their molecular mechanism in tumorigenesis has not been established.

A non-natural nucleotide uses a specific pocket to selectively inhibit telomerase activity.

open access: yesPLoS Biology, 2019
Telomerase, a unique reverse transcriptase that specifically extends the ends of linear chromosomes, is up-regulated in the vast majority of cancer cells.

The mRNA expression of hTERT in human breast carcinomas correlates with VEGF expression [PDF]

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

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.

The telomerase essential N-terminal domain promotes DNA synthesis by stabilizing short RNA-DNA hybrids. [PDF]

open access: yes, 2015
Telomerase is an enzyme that adds repetitive DNA sequences to the ends of chromosomes and consists of two main subunits: the telomerase reverse transcriptase (TERT) protein and an associated telomerase RNA (TER). The telomerase essential N-terminal (TEN)
