- n. An enzyme that is found in the telomeres of chromosomes in germ cells, stem cells, and most cancer cells and that preserves the length of telomeres across cell divisions.
- n. biochemistry, genetics An enzyme in eukaryotic cells that adds a specific sequence of DNA to the telomeres of chromosomes after they divide; gives the chromosomes stability over time.
- n. an enzyme in eukaryotic cells that can add telomeres to the ends of chromosomes after they divide
“I was working with an enzyme called telomerase, which is found only in cancer cells.”
“We know that telomerase is the enzyme that is needed to put the repeats on.”
“By providing, with its RNA, a template for DNA synthesis, telomerase is able to build a platform onto the end of the molecule from which other DNA-synthesizing enzymes can then operate.”
“Combining both protein and RNA components, telomerase is a reverse transcriptase which adds telomere DNA to the ends of molecules using an RNA template.”
“Specifically, an analysis of meditators 'white blood cells showed a 30 percent increase in an enzyme called telomerase, a chemical essential to the long-term health of the body's chromosomes and cells.”
“Moreover, when fighting infections, T-cells can turn on an enzyme called telomerase, which can prevent the telomeres from shortening....”
“The mice involved in the study were given an enzyme called telomerase, 4-OHT, to reactivate the telomeres in the body.”
“GV1001, made by South Korean pharmaceutical company KAEL GemVax, contains a fragment of an enzyme called telomerase, which is normally found in human embryos and which cancer cells use to divide unchecked.”
“But there's an enzyme called telomerase that reverses this process; it's one of the reasons cancer cells live so long.”
