WebMany recent advances have emerged in the telomere and telomerase fields. This Timeline article highlights the key advances that have expanded our views on the mechanistic underpinnings of telomeres and telomerase and their roles in ageing and disease. Three decades ago, the classic view was that tel … A telomere is a region of repetitive nucleotide sequences associated with specialized proteins at the ends of linear chromosomes. Telomeres are a widespread genetic feature most commonly found in eukaryotes. In most, if not all species possessing them, they protect the terminal regions of chromosomal DNA from progressive degradation and ensure the integrity of linear chromosomes by preventing DNA repair systems from mistaking the very ends of the DNA strand for a double-st…

WebOct 7, 2024 · Without telomerase, telomeres progressively shorten until they die or cease functioning. However, by activating telomerase, it is possible to actively restore telomeres and allow for many future cell divisions. This essentially slows your internal clock, inhibiting and even reversing many of the harmful effects of aging. ... WebIn addition, down-regulation of Bcl2 and survivin was observed in curcumin-treated cells. Besides these effects, we found curcumin to be inhibiting telomerase activity and down-regulating hTERT mRNA expression leading to telomere shortening. We conclude that telomerase inhibitory effects of curcumin underscore its use in adjuvant cancer therapy. J.
