I have personally known about the importance of Telomeres for years, but until recently the only known way to really boost the length of telomeres was an outrageously expensive supplement called T-65, that only the very rich could afford. Telomerase is een enzym dat in de celkern van bepaalde cellen voorkomt. Het bestaat voor een deel uit proteïne en voor een deel uit RNA. Het enzym is een reverse transcriptase, waarbij het RNA-gedeelte als matrijs gebruikt wordt. Telomerase herstelt het chromosoomeind, de zogenaamde telomeer.

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 telomeres are disposable buffers blocking the ends of eukaryotic chromosomes. The reverse transcriptase enzyme telomerase is activated in over 80% of tumour cells, and it undertakes the synthesis of further telomeric DNA repeats, so directly maintaining telomeres. The inhibition of telomerase leads to the senescence and eventual apoptosis of tumour cells, and thus telomerase is an attractive target for selective chemotherapy. Telomerase appears to be the enzyme that lays off the cellular clock of aging by providing additional DNA to the chromosomal duration and enabling cell division to continue to proliferate and revitalize. Therapies are being manufactured that may help to keep the dropping consequences of aging by keeping the length of our telomeres.

FREE Shipping by Amazon. Unlike viral or retroviral reverse transcriptases, such as that of HIV-1, the cellular enzyme telomerase specializes in making the multiple short tandem repeats that are at the ends of chromosomes. The protein component of telomerase, telomerase reverse transcriptase (TERT), is indeed a protein enzyme and its amino acid sequence includes reverse transcriptase motifs. Se hela listan på santescience.fr Telomerase is an RNA-dependent DNA polymerase, meaning an enzyme that can make DNA using RNA as a template. How does telomerase work?

Telomerase offsets cellular aging by Telomerase is the enzyme responsible for maintenance of the length of telomeres by addition of guanine-rich repetitive sequences.
