telomerase activity and telomere length in aml-m3 patients
introduction: the telomeric dna together with its associated proteins protects the chromosome ends from degradation or aberrant recombination. telomerase and telomere are closely associated with development of cancers. in this study we aim to investigate the significance of telomerase activity (ta) and telomere length (tl) in patients with acute promyelocytic leukemia (apl). methods: peripher...
متن کاملTelomerase Activity and Telomere Length in Daphnia
Telomeres, comprised of short repetitive sequences, are essential for genome stability and have been studied in relation to cellular senescence and aging. Telomerase, the enzyme that adds telomeric repeats to chromosome ends, is essential for maintaining the overall telomere length. A lack of telomerase activity in mammalian somatic cells results in progressive shortening of telomeres with each...
متن کاملThe effect of high intensity interval training on telomere length and telomerase activity in non-athlete young men
Introduction: Telomeres are DNA portions that are located on the two ends of the chromosome. Telomeres play an important role in cellular life. Exercise is one of the factors that contributes to their control. The purpose of the present study was to investigate the effect of 8 weeks of high intensity interval training (HIIT) on telomere length and telomerase activity in non-athletic young men. ...
متن کاملTelomerase Variant A279T Induces Telomere Dysfunction and Inhibits Non-Canonical Telomerase Activity in Esophageal Carcinomas
BACKGROUND Although implicated in the pathogenesis of several chronic inflammatory disorders and hematologic malignancies, telomerase mutations have not been thoroughly characterized in human cancers. The present study was performed to examine the frequency and potential clinical relevance of telomerase mutations in esophageal carcinomas. METHODS Sequencing techniques were used to evaluate mu...
متن کاملTelomerase activity and alterations in telomere length in human brain tumors.
Telomerase activity was examined in 170 human brain tumor tissues, and terminal restriction fragment (TRF) length was examined in 152 of the 170. Telomerase activity was detected in 61.7% (66 of 107) of the neuroepithelial tumors. However, the detection rates of telomerase activity were widely different for different histopathological entities. In the case of astrocytic tumors, the detection ra...
