WNT5A-NFAT Signaling Mediates Resistance to Apoptosis in
Moreover, the advantage of this DNA walker strategy was confirmed by calculating telomerase activity in a single cell. 2016-06-20 2000-06-12 2005-09-01 2004-11-01 We also analyzed telomerase activity in separated fractions and surprisingly, found that the fraction of cells that divided 0-1 time over 6 days in culture have several times higher endogenous 2016-06-01 2010-11-28 Human telomerase is a ribonucleoprotein complex that functions as a telomere terminal transferase by adding multiple TTAGGG hexamer repeats using its integral RNA as the template. There is a very strong association between telomerase activity and malignancy in … Telomerase Activity Showing all 22 results Sort by Featured Best Selling Alphabetically, A-Z Alphabetically, Z-A Price, low to high Price, high to low Date, new to old Date, old to new 2010-11-04 As an important biomarker for early cancer diagnostics and a valuable therapeutic target, telomerase has attracted extensive attention concerning its detection and monitoring. 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.

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.
snoRNPs Regulate Telomerase Activity in Neuroblastoma and
bestämningsmetod: IDA. DNA duplex unwinding. bestämningsmetod: IDA. positive regulation of helicase activity.
Comprehensive lifestyle changes significantly increase telomerase activity and consequently telomere maintenance capacity in human immune-system cells. Given this finding and the pilot nature of this study, we report these increases in telomerase activity as a significant association rather than inferring causation.

In human somatic cells proliferation potential is strictly limited and senescence follows approximat …. 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.
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.

Haematuria and inflammation reduced the specificity of telomerase assay, which reduced its validity as a tumor marker of bladder cancer.

However, the use of control groups was not part of the study's methodology and so weakens this association and provides speculation that cancer progression itself may be the agent responsible for increased telomerase activity. First, because telomerase activity is present in the germ cells of all mammals, we used testicular tissue as a positive control for the assay and specimen quality. However, the level of telomerase activity in the testes is developmentally regulated, and mature sperm is telomerase negative ( Prowse & Greider, 1995 ). Telomerase activity was measured by the TRAP assay and is expressed as a percentage of the activity detected in the lung carcinoma cell line GLC 4. (A) Telomerase activity in the original TRAP assay. Telomerase activity in 130, 13, and 1.3 GLC 4 cell equivalents is shown at the left.
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. The activity of telomerase allows cancer cells to replicate and proliferate in an uncontrolled manner, to infiltrate tissue, and to metastasize to distant organs. regulation of telomerase activity in tumorigenesis. Telomeres comprise the nucleoprotein complexes that cap the ends of eukary-otic chromosomes and are maintained by a specialized reverse transcriptase, telomerase.18 Human telomerase is composed of an RNA subunit known as hTER (human telomerase … The researchers of a new study have demonstrated that it is possible to restore lost telomerase activity in stem cells that have been affected by telomere biology diseases . They show that by using PAPD5 inhibitors, it is possible to restore lost telomere length both in vitro and in mice.
