A genome-wide association study was conducted to identify expression quantitative trait loci (eQTL) for human telomerase.We tested the genetic associations of nucleotide variants with expression of the genes encoding human telomerase reverse transcriptase (hTERT) and telomerase RNA components (TERC) in lymphoblastoid cell lines derived from 373 Europeans.Our results revealed 6 eQTLs associated ...

results the median level of pbmcs htert mrna in survivors increased with treatment time and was significantly higher than the corresponding level in non-survivors after 14 days of treatment (p < 0.001). subgroup analyses showed that the levels of pbmcs htert mrna were remarkably higher in patients with acute-on-chronic liver failure than in those with chronic liver failure (p < 0.05). in patien...

Somatic mutations in the promoter region of human telomerase reverse transcriptase (hTERT) gene have been identified many types cancer. The hTERT is known to be enriched with sequences that enable formation G-quadruplex (G4) structures, whose presence associated elevated mutagenicity and genome instability. Here, we used a bioinformatics tool (QGRS mapper) search for G4-forming (G4 motifs) 1000...

Human telomerase reverse transcriptase (hTERT; the catalytic protein subunit of telomerase) is subjected to numerous alternative splicing events, but the regulation and function of these splice variants is obscure. Full-length hTERT includes conserved domains that encode reverse transcriptase activity, RNA binding, and other functions. The major splice variant termed α+β- or β-deletion is highl...

BACKGROUND AND OBJECTIVES Acute myeloid leukemia (AML) is a malignant, genetically heterogenous disorder characterized by uncontrolled growth of immature myeloid cells. The aim of this study was to analyze whether telomere length and/or hTERT expression are correlated with clonal chromosomal aberrations in AML. DESIGN AND METHODS Telomere length in mononuclear cells derived from 137 previousl...

PURPOSE Preliminary evidence indicates that telomerase activity is significantly less expressed in typical carcinoids than in large cell neuroendocrine carcinomas or in small cell lung cancers. Knowledge of the mechanisms by which telomerase is differentially regulated in neuroendocrine lung tumors is important for a better understanding of the pathogenesis of these malignancies. EXPERIMENTAL...

With increasing frequency during serial passage in culture, primary human keratinocytes express p16(INK4A) (p16) and undergo senescence arrest. Keratinocytes engineered to express hTERT maintain long telomeres but typically are not immortalized unless, by mutation or other heritable event, they avoid or greatly reduce p16 expression. We have confirmed that keratinocytes undergo p16-related sene...

Objective: To Research of hiperfect-mediated RNA interference targeting human telomerase reverse transcriptase gene (hTERT) on the biological behavior malignant melanoma cell line A375.Methods: Specific siRNAs with green fluorescent labeling different concentrations were transfected into A375 cells by using transfection reagent (Hiperfect) at volumes . The efficiency was determined fluorescen m...
