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

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

ESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Multi‐Cohort Analysis Reveals Genetic Predispositions to Clonal Hematopoiesis as Mutation‐Specific Risk Factors for Stroke

Advanced Genetics, Volume 6, Issue 1, March 2025.
This study comprehensively evaluated the differential effect of clonal hematopoiesis (CH) mutations on the risk of various stroke subtypes and functional recovery. It shows that TET2 is associated with small vessel stroke possibly via a pro‐inflammatory pathway. Abstract Recent observational studies have found an association between Clonal Hematopoesis

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.

Telomerase reverse transcriptase gene amplification in hematological malignancies

Egyptian Journal of Medical Human Genetics, 2019
Background Telomere is a complex DNA–protein structure located at the end of all eukaryotic chromosomes. The major role of human telomerase is to catalyze the addition of telomeric repeat sequences TTAGGG onto chromosome ends for stabilization of ...

Telomerase catalysis: A phylogenetically conserved reverse transcriptase [PDF]

Proceedings of the National Academy of Sciences, 1998
Replication of telomeres, the ends of eukaryotic chromosomes, is the responsibility of the enzyme telomerase. Since its discovery 13 years ago, research on this unusual DNA polymerase has revealed a series of surprises. The first of these was the realization that information within the enzyme itself determines the sequence of its product: a portion of ...

Hyperoside alleviates endometrial stromal cell senescence in unexplained recurrent spontaneous abortion via DHX9‐mediated R‐loop resolution

iMeta, EarlyView.
This study suggests that the food‐derived flavonoid hyperoside may act as a natural DExH‐box helicase 9 (DHX9) modulator, directly targeting Thr419 of DHX9 to help resolve pathological R‐loop accumulation. Consequently, it suppresses cyclic GMP‐AMP synthase‐stimulator of interferon genes (cGAS‐STING)‐driven endometrial stromal senescence and restores ...

The Roles of Telomerase in the Generation of Polyploidy during Neoplastic Cell Growth

Neoplasia: An International Journal for Oncology Research, 2013
Polyploidy contributes to extensive intratumor genomic heterogeneity that characterizes advanced malignancies and is thought to limit the efficiency of current cancer therapies.
