Human telomerase reverse transcriptase (hTERT) is the catalytic component of telomerase that facilitates tumor cell invasion and proliferation. It has been reported that telomerase and hTERT are significantly upregulated in majority of cancers including cervical cancer, thus, downregulation of hTERT is a promising target in malignant tumor treatment. We established a short interfering RNA (siRN...

Upregulated expression and activation of human telomerase reverse transcriptase (hTERT) is a hallmarker of lung tumorigenesis. However, the mechanism underlying the aberrant hTERT activity in lung cancer cells remains poorly understood. In this study, we found the transcriptional co-activator CBP as a new hTERT promoter-binding protein that regulated hTERT expression and tumor growth in lung ad...

HIV-1 derived lentiviral vectors (LVs) have emerged as a powerful tool for gene delivery. hTERT is an ideal tumor-associated antigen with which to develop a potential dendritic cell (DC) vaccine. The purpose of this study was to construct a recombinant lentivirus vector of the hTERT peptide and to determine the hTERT-specific cytotoxic T lymphocyte response elicited by DCs transfected with hTER...

PURPOSE Colorectal cancer (CRC) is one of the most common cancers in western countries. Identification of circulating markers for CRC would optimize early stage diagnosis and the monitoring for disease recurrence. Expression of telomerase reverse transcriptase (hTERT) is essential to the oncogenic process and might be used as a molecular marker of neoplastic disease. EXPERIMENTAL DESIGN Eight...

Bladder cancer is one of the most common forms of cancers in the world. The current gold standards for itsdiagnosis are cystoscopy and urine cytology. Cystoscopy, a naked eye assessment of the bladder, is invasive, uncomfortable and costly with a great deal of personal variability in its results; while urine cytology has high specificity but low sensitivity, particularly for low-grade les...

Hypoxia-inducible factor-1alpha (HIF-1alpha) has been implicated in the transcriptional regulation of the telomerase reverse transcriptase (hTERT) gene expression and telomerase activity, essential elements for cellular immortalization and transformation. However, controversial results were obtained in different studies. Moreover, it is totally unclear whether HIF-2alpha, the paralog of HIF-1al...

The elevated expression and activation of human telomerase reverse transcriptase (hTERT) is associated with the unlimited proliferation of cancer cells. However, the excise mechanism of hTERT regulation during carcinogenesis is not well understood. In this study, we discovered cleavage and polyadenylation specific factor 4 (CPSF4) as a novel tumor-specific hTERT promoter-regulating protein in l...

BACKGROUND Lysine-specific demethylase 1 (LSD1), catalysing demethylation of mono- and di-methylated histone H3-K4 or K9, exhibits diverse transcriptional activities by mediating chromatin reconfiguration. The telomerase reverse transcriptase (hTERT) gene, encoding an essential component for telomerase activity that is involved in cellular immortalization and transformation, is silent in most n...
