Prognostic Relevance of hTERT mRNA Expression in Ductal Adenocarcinoma of the Pancreas

open access: yesNeoplasia: An International Journal for Oncology Research, 2008
Telomerase is thought to play an essential role in tumorigenesis and progression. Its activity is directly correlated with the expression of its catalytic subunit, human telomerase reverse transcriptase (hTERT).

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.

Modulation of human telomerase reverse transcriptase in hepatocellular carcinoma

open access: yesWorld Journal of Gastroenterology, 2004
Most cancer cells acquire immortal capability by telomerase activation. The human telomerase reverse transcriptase gene (hTERT) is considered to be the major determinant of the enzymatic activity of human telomerase, and the hTERT promoter contains several c-Myc binding sites that mediate hTERT transcriptional activation.

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 ...

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

The Roles of Telomerase in the Generation of Polyploidy during Neoplastic Cell Growth

open access: yesNeoplasia: An International Journal for Oncology Research, 2013
Polyploidy contributes to extensive intratumor genomic heterogeneity that characterizes advanced malignancies and is thought to limit the efficiency of current cancer therapies.

TAK1 represses transcription of the human telomerase reverse transcriptase gene [PDF]

open access: yesOncogene, 2007
In human cells, telomerase activity is tightly regulated by the expression of its catalytic subunit, namely, the human telomerase reverse transcriptase (hTERT). However, the molecular mechanisms involved in the regulation of hTERT expression have not been completely clarified.

An Alternate Splicing Variant of the Human Telomerase Catalytic Subunit Inhibits Telomerase Activity

open access: yesNeoplasia: An International Journal for Oncology Research, 2000
Telomerase, a cellular reverse transcriptase, adds telomeric repeats to chromosome ends. In normal human somatic cells, telomerase is repressed and telomeres progressively shorten, leading to proliferative senescence.

Alternative Splicing of Human Telomerase Reverse Transcriptase May Not Be Involved in Telomerase Regulation During all-trans-Retinoic Acid-Induced HL-60 Cell Differentiation

open access: yesJournal of Pharmacological Sciences, 2004
Alternative splicing of the human telomerase reverse transcriptase subunit (hTERT) suppresses telomerase activity during the development of human fetal kidney cells into mature cells.

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.
