WitrynaAt the organism level, telomerase is inactivated in somatic cells, whose telomeres shorten each time they proliferate [ 1, 2 ]. In embryonic tissues and adult stem cells (e.g., hematopoietic stem cells), telomerase is expressed as a mechanism to maintain proper telomere lengths [ 3, 4, 5 ].

WitrynaThe analysis of telomeres could enhance the existing assays, providing valuable information regarding cancer diagnosis, prognosis, and treatment response. Furthermore, it may contribute to a better comprehension of the mechanisms essential for the development and progression of various cancers. WitrynaCycloastragenol (CAG) is an aglycone of astragaloside IV. It was first identified when screening Astragalus membranaceus extracts for active ingredients with antiaging properties. The present study demonstrates that CAG stimulates telomerase activity and cell proliferation in human neonatal keratinocytes.

Witryna2 lip 2024 · Telomerase is almost universally expressed in tumor cells but not in normal cells. The nucleoside analog 6-thio-dG is directly incorporated into telomeres by telomerase, where it rapidly induces telomere damage in telomerase-positive cancer cells but not in normal telomerase-silent normal cells. WitrynaHigh telomerase activity was found in cancer cells, but not in differentiated homologous nonmalignant tissues. We demonstrated previously that the disappearance of telomerase activity is a reliable marker of tumor cell killing in human cancer cell lines.
