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

Journal 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.

Gastrointestinal cancer cells treatment with bevacizumab activates a VEGF autoregulatory mechanism involving telomerase catalytic subunit hTERT via PI3K-AKT, HIF-1α and VEGF receptors. [PDF]

PLoS ONE, 2017
Targeting angiogenesis has been considered a promising treatment of choice for a large number of malignancies, including gastrointestinal cancers. Bevacizumab is an anti-vascular endothelial growth factor (anti-VEGF) being used for this purpose. However,

A Cytosine‑Bulged (3+1) Hybrid G‑Quadruplex Formed by the Chicken DNA Replication Origin

Chemistry – A European Journal, EarlyView.
The first high‐resolution structure of an OGRE‐derived G‐quadruplex from the chicken β‐globin replication origin reveals an intramolecular three‐layer (3+1) hybrid fold with a cytosine bulge and an unprecedented 5'‐outer‐quartet anti guanine, creating a distinctive surface for molecular recognition.

siRNA suppression of hTERT using activatable cell-penetrating peptides in hepatoma cells

Bioscience Reports, 2015
Activatable cell-penetrating peptides (aCPPs) allow non-viral, low cytotoxic and selective delivery of compounds into target cells for cancer therapy. In tumour cells, up-regulation of human telomerase reverse transcriptase (hTERT) frequently occurs and ...

The womb as the cradle of longevity: Perinatal origins of biological aging

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract The perinatal period is increasingly recognized as an important determinant of biological aging trajectories and disease susceptibility across the lifespan. This narrative review synthesizes current evidence linking intrauterine exposures to adult health outcomes across three biological dimensions: fetal programming, maternal influences, and ...

In‐frame variants in TP53 gene identified in adult leukemia samples are predominantly deleterious: a study of the TP53 Network of Education and Research Initiative on CLL

The Journal of Pathology, EarlyView.
Abstract The prognostic and predictive impact of TP53 variants in leukemia led to their inclusion in diagnostic and treatment guidelines, increasing the demand for rapid, reliable laboratory analysis, interpretation, and reporting. While most TP53 variants identified in tumor samples can be interpreted using data from large‐scale functional studies ...

Correlation between p38 mitogen-activated protein kinase and human telomerase reverse transcriptase in sarcomas

Journal of Experimental & Clinical Cancer Research, 2012
Background One of the major components of telomerase is the human telomerase reverse transcriptase (hTERT) as the catalytic protein. hTERT mRNA expression are reported to be associated with prognosis and tumor progression in several sarcomas.

The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

CDC5L Promotes hTERT Expression and Colorectal Tumor Growth

Cellular Physiology and Biochemistry, 2017
Background/Aims: Colorectal cancer (CRC) is the third leading cause of cancer-related death worldwide because the survival rate remains low. Cell division cycle 5-like (CDC5L) is highly expressed in some cancer cells, but the mechanism requires ...

D‐amino acid oxidase as a chemogenetic tool for spatiotemporally controlled hydrogen peroxide production: The oxygen connection

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose D‐amino acid oxidase (DAO) has been developed as a chemogenetic tool, to precisely manipulate redox levels in tissues and cells by generating H2O2 in the presence of D‐amino acids. The enzyme's significant oxygen consumption during H2O2 production may influence cellular oxygen levels.
