Human telomerase reverse transcriptase expression in ovarian tumors

Indian Journal of Pathology and Microbiology, 2012
Background : Ovarian cancer is the 6 th most common cancer among women. In ovarian tumors, the borderline category is not well defined due to the difficulty in assessing stromal invasion. The World Health Organization (WHO) defined it as tumor that lacks

Human telomerase reverse transcriptase (hTERT) Q169 is essential for telomerase function in vitro and in vivo. [PDF]

PLoS ONE, 2009
BACKGROUND:Telomerase is a reverse transcriptase that maintains the telomeres of linear chromosomes and preserves genomic integrity. The core components are a catalytic protein subunit, the telomerase reverse transcriptase (TERT), and an RNA subunit, the

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 ...

Influence of Human Telomerase Reverse Transcriptase Mutation on the Aggressiveness and Recurrence in Meningiomas. [PDF]

Cureus, 2021
 Over 200 human telomerase reverse transcriptase (hTERT) polymorphism combinations have been implicated in the development of cancer. This study aimed to evaluate hTERT mutations in meningioma tissue and its association with meningioma.A total of 90 patients who underwent surgery between 2006 and 2015 and were histopathologically diagnosed with ...

Functional Multimerization of the Human Telomerase Reverse Transcriptase [PDF]

Molecular and Cellular Biology, 2001
The telomerase enzyme exists as a large complex (approximately 1,000 kDa) in mammals and at minimum is composed of the telomerase RNA and the catalytic subunit telomerase reverse transcriptase (TERT). In Saccharomyces cerevisiae, telomerase appears to function as an interdependent dimer or multimer in vivo (J. Prescott and E. H.

Multiomics identifies the link between intratumor steatosis and the exhausted tumor immune microenvironment in hepatocellular carcinoma

Hepatology, EarlyView., 2022
Steatotic HCC can be diagnosed by MRI and forms a pro‐tumor immune microenvironment with high expression of PD‐L1, M2 polarization of macrophages and activation of CAFs, which may be a good target for combined immunotherapy. Abstract Background and Aims Immunotherapy has become the standard‐of‐care treatment for hepatocellular carcinoma (HCC), but its ...

Telomerase Activity Reconstituted in Vitro with Purified Human Telomerase Reverse Transcriptase and Human Telomerase RNA Component [PDF]

Journal of Biological Chemistry, 2000
Telomerase is a specialized reverse transcriptase that catalyzes elongation of the telomeric tandem repeat, TTAGGG, by addition of this sequence to the ends of existing telomeres. Human telomerase reverse transcriptase (hTERT) has been identified as a catalytic enzyme involved in telomere elongation that requires telomerase RNA, human telomerase RNA ...

Human Specific Regulation of the Telomerase Reverse Transcriptase Gene [PDF]

Genes, 2016
Telomerase, regulated primarily by the transcription of its catalytic subunit telomerase reverse transcriptase (TERT), is critical for controlling cell proliferation and tissue homeostasis by maintaining telomere length. Although there is a high conservation between human and mouse TERT genes, the regulation of their transcription is significantly ...

Transcriptional regulation of the human telomerase reverse transcriptase [PDF]

Transcription, 2010
hTERT and NFAT were thought until recently to belong to separate metabolic compartments. The involvement of NFAT in the induction of hTERT transcription suggested by hTERT expression variations during lymphocyte stimulation and immunosuppressive treatments explains the link between hTERT expression and cell stimulation and offers new insights for ...
