Herein, a homogeneous electrochemical strategy based on T7 exonuclease-aided target recycling amplification is proposed for a simple, rapid, and highly sensitive assay of human telomerase activity from crude cancer cell Telomerase plays a vital role in cancer and aging, and telomerase activity detection has drawn great attention recently. However, a feasible in situ imaging system for intracellular telomerase is still a challenge. Here, we develop a novel approach to image intracellular telomerase activity using DNA-based c This method realized the sensing of telomerase activity in HeLa cell extract with a detection limit below 1.6×10 −6 IU μL −1. The real‐time in situ observation of telomerase extension was achieved in living HeLa cells. This strategy has been applied to monitor the efficiency of telomerase… The telomerase RNA component contains a species-specific template for synthesis of telomeric repeats, and such RNA sequences have been cloned from ciliates,10 yeast,11,12 mouse,13and human.14 Recently, the gene encoding the reverse transcriptase catalytic subunit of telomerase from several species including humans has also been cloned.15,16 In humans, telomerase activity is readily … Telomerase, an enzyme responsible for the synthesis of telomeres, is activated in many cancer cells and is involved in the maintenance of telomeres.

Telomerase is the enzyme responsible for 1998-01-06 Telomerase Telomerase. The maintenance of telomeres by the cellular ribonucleoprotein enzyme telomerase is of well-documented Stem Cells Derived from Amniotic Fluid and Placenta. Paolo De Coppi, Telomerase activity was evaluated using RNA-Processing Dysfunction in Spinal Muscular 2018-12-11 2021-01-08 2018-11-28 Telomerase is not usually active in most somatic cells (cells of the body), but it’s active in germ cells (the cells that make sperm and eggs) and some adult stem cells. These are cell types that need to undergo many divisions, or, in the case of germ cells, give rise to a … 2018-02-27 It has been proposed that the biological clock underlying the limited division potential of eukaryotic cells is telomere length. We assayed telomerase activity in single cells of the hematopoietic and immune systems. We examined hematopoietic stem cells at four stages of differentiation, lineage-committed progenitors, and mature myeloid and The researchers found that these healthy lifestyle inclusions significantly increased telomerase activity and thus telomere maintenance in study participants.

The telomerase activity, measured by telomeric repeat amplification protocol, was positive in 81% of colorectal cancers, 70% of gastric cancers, and 93% of breast cancers. Telomerase is a ribonucleoprotein that is also called telomerase reverse transcriptase. Telomerase activity is widely regulated owing to its important role in the maintenance of genome integrity. Multicellular organisms display tissue-specific, developmental and stress response strategies for telomerase suppression [ 59, 60 ].
