Telomerase enzyme activity underpins the unrestricted proliferation of cancer cells in approximately 80-90% of malignancies, including acute leukemias and lymphomas.7 4 It also plays an important role in the function of normal hematopoietic stem and progenitor cells (HSPC).11 8 Telomerase activity is low in quiescent hematopoietic stem cells, and is upregulated by self-renewal cytokines that

These caps are called “telomeres.” Each time our cells divide, they must replicate their DNA so that each daughter cell gets a full set of operating instructions. 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 ]. 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.
