Funktion. Telomeras är ett omvänt transkriptas, det vill säga enzymet använder RNA som mall för att skapa DNA. Telomeras attraheras till TTAGGG-repeats, telomerer, i slutet på kromosomerna. Den binder till och förlänger telomersekvensen genom att använda RNA som mall för att skapa TTAGGG-repeats (hos människan). telomerase regulators such as its inhibitors and activa-.

Telomeres protect the vital information in our DNA DNA makes up all of the cells in our body. It is the genetic material that makes us who we are.

Development of adenoviral vectors for monitoring telomerase

Active in progenitor and cancer cells. Inactive  6 Nov 2019 Mitochondrial functions and telomere functions have mostly been studied independently. In recent years, it, however, has become clear that  A telomere is a repeating DNA sequence (for example, TTAGGG) at the end of the body's chromosomes. The telomere can reach a length of 15,000 base pairs.

Here we review the role of telomeres and telomerase in the function and capacity of the human stem cells. Telomeres, guanine-rich tandem DNA repeats of the chromosomal end, provide chromosomal Telomerase is commonly expressed in human cancer cells. 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. Augmenting and regulating telomerase function will have to be performed with precision, walking a narrow line between cell rejuvenation and a heightened risk for cancer development. Telomerase allows these cells to divide many times without becoming damaged or undergoing apoptosis. Telomerase is also abnormally active in most cancer cells, which grow and divide without control or order.
