While telomerase can counteract shortening by elongating and protecting telomeres, telomerase activity is generally down-regulated in normal human cells
Haematuria and inflammation reduced the specificity of telomerase assay, which reduced its validity as a tumor marker of bladder cancer. K19 and K20 are the best candidates as screening tests for the diagnosis of bladder cancer, representing the highest sensitivity and specificity, beside the radiological and histopathology.
However, telomerase activity is found in almost all human cancer cell lines and in about 85%-90% of primary tumours [ 24]. 2015-05-11 2021-01-15 2020-11-07 Telomerase activity assessed as expression of telomerase reverse transcriptase, hTERT, and telomerase RNA component, hTERC, was gradually decreased during 6 to 11 weeks of gestation . In examining the dynamics of TL from 15 to 19 weeks of human gestation, no association between TL and gestational age was found in the study by Youngren et al. [ 25 ]. Based on signal amplification of the telomerase-triggered DNA walker, the walking device was further applied to various cancer lines with a low detection limit of telomerase activity equivalent to 90 cells μL –1 for HeLa cells.
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 activity in 130, 13, and 1.3 GLC 4 cell equivalents is shown at the left. 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. Telomerase deficiency has been linked to diabetes and impaired insulin secretion in mice. Inflammation in our body can decrease our telomerase 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. Larger randomised controlled trials are warranted to confirm the findings of
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.

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 [1]. They show that by using PAPD5 inhibitors, it is possible to restore lost telomere length both in vitro and in mice.
