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?

Most malignant tumours, including lymphomas, are telomerase-positive and this telomere length, telomerase activity, malignant lymphoma, relapse, tumour

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.

Psychoneuroendocrinology, 2014, 42 Telomerase is the enzyme responsible for maintenance of the length of telomeres by addition of guanine-rich repetitive sequences. Telomerase activity is exhibited in gametes and stem and tumor cells. In human somatic cells proliferation potential is strictly limited and senescence follows approximately 50-70 cell divisions.

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

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.
