In this model, telomerase activation occurs after the selection of mutations that stimulate abnormal cell proliferation, and, thus, telomerase activation may be a relatively late event in tumor initiation that allows for genome stability after the acquisition of cancer-associated mutations.

Se hela listan på academic.oup.com In cancer, telomerase becomes active during telomere crisis and rescues the genomically abnormal cells by lengthening telomeres. In a series of experiments in a lymphoma mouse model, the team found: 2018-01-01 · Interestingly, SNPs of telomerase encoding genes that are associated with an increased cancer risk in human populations were shown to lead to either increases or decreases in telomerase activity and telomere length (see for example (Bojesen et al., 2013, Killedar et al., 2015).

Translations in context of "TELOMERASE" in english-swedish. tumors Other important functions of telomerase have been discovered which are not necessary​ 

Increased telomerase expression produces vulnerability of cancer cells, distinguishing them from normal cells in the body, although normal cells do also have some active telomerase. Recent studies also suggest that telomerase is implicated in tumor progression in unexpected ways. Telomerase and Cancer Abstract.

Telomerase and cancer

Interindividual variation in mean leukocyte telomere length (LTL) is associated with cancer and several age-associated diseases. We report here a genome-​wide  in Humans Links Nucleotide Metabolism to Leukocyte Telomere Length. JSON the risk of thyroid cancer, lymphoma, and a range of proliferative conditions. 2 dec. 2019 — Ändarna av kromosomerna utgörs av en specifik repetitiv DNA-sekvens som kallas för telomerer vilka är viktiga vid cancerutveckling.

In the large majority of cancer cells, telomere length is maintained by telomerase. Thus, telomere length and telomerase activity are crucial for cancer initiation and the survival of tumors.

Telomeres maintain genomic integrity in normal cells, and their progressive shortening during successive cell divisions induces chromosomal instability. In the large majority of cancer cells, telomere length is maintained by telomerase. Thus, telomere length and telomerase activity are crucial for cancer initiation and the survival of tumors.

Cancer cells make telomerase, however, preventing the telomeres from becoming so short that the cells can no longer survive.
