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 ...

A putative cap binding protein and the methyl phosphate capping enzyme Bin3/MePCE function in telomerase biogenesis

Nature Communications, 2022
Most eukaryotes maintain telomeres using a specialized reverse transcriptase. Here the authors report that Thc1 (Telomerase Holoenzyme Component 1) and Bmc1 (Bin3/MePCE 1) form a complex with Pof8, a constitutive member of telomerase in fission yeast.

In silico prediction of telomerase reverse transcriptase inhibitors using modified retinol for the treatment of arsenical cancer

Bangabandhu Sheikh Mujib Medical University Journal, 2016
Retinol molecule was modified to predict the inhibitors of telomerase reverse transcriptase for the treatment of arsenical cancer through in silico study. Telomerase activity is expressed in the cancerous conditions which can be the target for anticancer

Normal and Tumour Tissue mRNA Expressions of Telomerase Complex Genes in Several Types of Cancer

Balkan Medical Journal, 2017
Aims: To investigate the changes in mRNA expression levels of telomerase-related significant proteins in several types of cancer. Methods: Human telomerase reverse transcriptase, pontin, reptin and dyskerin expressions were measured in normal and tumour

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 ...

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 ...

In vitro and ex vivo inhibition of human telomerase by anti-HIV nucleoside reverse transcriptase inhibitors (NRTIs) but not by non-NRTIs.

PLoS ONE, 2012
Telomerase is a specialized reverse transcriptase responsible for the de novo synthesis of telomeric DNA repeats. In addition to its established reverse transcriptase and terminal transferase activities, recent reports have revealed unexpected cellular ...

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

Frontiers 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.

Telomerase Reverse Transcriptase Regulates microRNAs

International Journal of Molecular Sciences, 2015
MicroRNAs are small non-coding RNAs that inhibit the translation of target mRNAs. In humans, most microRNAs are transcribed by RNA polymerase II as long primary transcripts and processed by sequential cleavage of the two RNase III enzymes, DROSHA and DICER, into precursor and mature microRNAs, respectively.

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

PLoS 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.
