The close association between telomerase and human malignancies makes it one of the most common tumor molecular markers, and thus it is of great significance to measure telomerase activity in tumor cells [ 10 ]. Since telomerase was discovered in 1985 [ 11 ], a great deal of assays have been presented for telomerase activity determination.

Oct 6, 2017 The limiting determinant of telomerase activity is the catalytic component TERT, and TERT expression is closely correlated with telomerase

Biological psychiatry, 66(1), 25-32.

Telomerase activity

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 ].

Telomerase is an enzyme that regulates the lengths of telomeres in the cells of many organisms, and in humans it begins to function int the early stages of embryonic development. Telomeres are repetitive sequences of DNA on the ends of chromosomes that protect chromosomes from sticking to each other or tangling. Telomerase is an enzyme found inside our cells, which may be related to the aging process. It adds short, repetitive “caps” to our DNA strands.

en Normal somatic cells, on the other hand, do not have detectable telomerase activity.

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 [1].

Multicellular organisms display tissue-specific, developmental and stress response strategies for telomerase suppression [ 59, 60 ]. 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. Telomerase is an enzyme that regulates the lengths of telomeres in the cells of many organisms, and in humans it begins to function int the early stages of embryonic development.

Telomerase activity and telomere maintenance are important prerequisites for cellular ‘immortality,’ a state which characterizes the vast majority of cancerous cells. In addition to germline and embryonic stem cells, high telomerase activity is also found in most cancer cells. Telomerase Some cells have the ability to reverse telomere shortening by expressing telomerase, an enzyme that extends the telomeres of chromosomes. Telomerase is an RNA-dependent DNA polymerase, meaning an enzyme that can make DNA using RNA as a template. How does telomerase work? Telomerase Activity Is Associated with Cell Proliferation in Cultured Cells.
