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

, 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)

Telomerase reverse transcriptase moonlights: Therapeutic targets beyond telomerase

Cancer 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.

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

Nature 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 ...

The predictive and prognostic potential of plasma telomerase reverse transcriptase (TERT) RNA in rectal cancer patients [PDF]

, 2018
Background: Preoperative chemoradiotherapy (CRT) followed by surgery is the standard care for locally advanced rectal cancer, but tumour response to CRT and disease outcome are variable.

AZT as a telomerase inhibitor

Frontiers 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 ...

Single cell measurement of telomerase expression and splicing using microfluidic emulsion cultures. [PDF]

, 2014
Telomerase is a reverse transcriptase that maintains telomeres on the ends of chromosomes, allowing rapidly dividing cells to proliferate while avoiding senescence and apoptosis.

CDK1 dependent phosphorylation of hTERT contributes to cancer progression

Nature 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 ...

KMT2A promotes melanoma cell growth by targeting hTERT signaling pathway. [PDF]

, 2017
Melanoma is an aggressive cutaneous malignancy, illuminating the exact mechanisms and finding novel therapeutic targets are urgently needed. In this study, we identified KMT2A as a potential target, which promoted the growth of human melanoma cells ...

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

, 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.

Regulation of the human telomerase reverse transcriptase gene [PDF]

Oncogene, 2002
Most somatic human cells lack telomerase activity because they do not express the telomerase reverse transcriptase (hTERT) gene. Conversely, most cancer cells express hTERT and are telomerase positive. For most tumors it is not clear whether hTERT expression is due to their origin from telomerase positive stem cells or to reactivation of the gene ...
