The Nobel Prize in Physiology or Medicine 2009 was awarded jointly to Elizabeth H. Blackburn, Carol W. Greider and Jack W. Szostak "for the discovery of how chromosomes are protected by telomeres and the enzyme telomerase".

Levels of telomerase activity of the L866Y enzyme were also similar to wild-type enzyme activity levels when telomerase was reconstituted in HA5 cells, a human embryonic kidney cell line with limited lifespan that expresses SV40 large T and small t antigens (Stewart and … 1. Introduction. Telomerase is a ribonucleoprotein complex, composed of a reverse transcriptase enzyme catalytic subunit and a long non-coding RNA that contains the template sequence for telomere synthesis [1, 2] and is required for linear chromosome maintenance in most eukaryotes.The enzyme telomerase is active in germ cells and during early embryogenesis, ensuring restoration of telomere Telomere and Telomerase protect chromosome ends the Telomerase enzyme that maintains Telomere length. Scientific research has discovered that a primary cause of aging is shortening telomeres, the protective end-caps of DNA at both ends of every chromosome. You can avoid telomere shortening with diet and exercise, but only up to a point. Telomerase is a reverse transcriptase enzyme that carries its own RNA molecule (e.g., with the sequence 3′-CCCAAUCCC-5′ in Trypanosoma brucei) which is used as a template when it elongates telomeres.

. Telomerase activation by natural molecules has been suggested to be an anti‑aging modulator that can play a role in the treatment of aging‑related diseases.

Telomerase is the enzyme responsible for maintenance of the length of telomeres by addition of guanine-rich repetitive sequences. Telomerase activity is exhibited in gametes and stem and tumor cells. In human somatic cells proliferation potential is strictly limited and senescence follows approximat …. Telomerase: structure, functions, and activity Telomerase is a ribonucleoprotein that is also called telomerase reverse transcriptase. The telomerase enzyme acts as a reverse transcriptase that uses parts of human telomerase–associated RNA (hTR) as a template for telomeric repeat synthesis. The telomerase enzyme is a reverse transcriptase enzyme that adds DNA back to the ends of the telomere caps on chromosomes. The telomerase enzyme is able to do this by copying part of its RNA into the DNA of the telomere.

Telomerase Enzyme. Telomerase enzyme is a vital enzyme for cell survival that prevents telomere shortening; consequently, cellular senescence is observed after many cell division rounds. By increasing the expression and reactivation of the telomerase complex, cancer cells bypass cellular senescence.

Telomeres are specialized DNA-protein complexes found at the end of all linear chromosomes. Telomerase is an enzyme in our bodies that helps us maintain the protective telomeres located at the ends of all chromosomes. Telomerase is the key to healthy cell division. Recent studies have shown that increasing telomerase activity in our cells can increase the telomeres length, improve the function and promote the lifespan of our cells. Inhibiting telomerase, an enzyme that rescues malignant cells from destruction by extending the protective caps on the ends of chromosomes, kills tumor cells but also triggers resistance pathways that allow cancer to survive and spread, scientists report in the Feb. 17 issue of Cell.
