Sentences with phrase «called telomerase»

Astragalus contains an enzyme called telomerase, whose anti-aging potential was mentioned in the November 2008 issue of NewScientist.

Successful cancer cells are the ones that have evolved mutations that exploit one of the cell's two systems for renewing telomeres: either a primary system called telomerase, or in a few cases an «alternative» system appropriately called Alternative Lengthening of Telomeres (ALT).

Telomeres don't shrink significantly in healthy humans for decades due to an enzyme called telomerase, which partially repairs and lengthens them after each shortening.

The suspected immortalizing agent is an enzyme called telomerase (tee - LOW - mer - ace) that adds DNA to the endcaps, or telomeres, of the cell's chromosomes.

An enzyme called telomerase maintains telomeres in our reproductive and stem cells but not in the rest of the body.

An unusual enzyme called telomerase acts on parts of chromosomes known as telomeres.

As a safeguard, in cells such as egg, sperm, and stem cells, an enzyme called telomerase is responsible for preventing this wear and tear by maintaining telomere length.

Now two reports show that, with the help of an enzyme called telomerase, human cells can divide forever in the laboratory without turning cancerous.

One strategy, which occurs in about 90 percent of cancers, requires increase production of a telomere - elongating enzyme called telomerase.

The variant lies near a gene called telomerase RNA component, or TERC, and earlier studies in animals have shown that low TERC expression is associated with shorter telomeres, and faster biological aging.

Experiments confirmed that there was an enzyme, which we called telomerase, and that it is actually doing something inside cells that matters.

The Geron gene made a protein called telomerase.

The key to immortalization is an enzyme called telomerase, which keeps chromosomes healthy in cells that divide frequently.

Before now, researchers knew about only one enzyme, called telomerase, that could delay aging.

Variants in the gene called Telomerase Reverse Transcriptase (TERT) on chromosome 5 that were associated with older IEAA were also associated with longer telomeres indicating a critical role for TERT in regulating the epigenetic clock, in addition to its established role of compensating for cell replication - dependent telomere shortening.

Not exact matches

Telomerase is an enzyme that replicates the ends of chromosomes (sections of DNA called telomeres), replacing the DNA lost when chromosomes are copied before cell division and, therefore, maintaining the stability of the genome.

The scientists speculated that when chromosome tips get too stubby — a process that can be reversed by telomerase, an enzyme made up of protein and RNA — cells cease replicating and enter a state called senescence (see» More Than a Sum of Our Cells»).

UCLA researchers have found that a Chinese herbal regimen called TSY - 1 (Tianshengyuan - 1) increased telomerase activity in normal blood cells but decreased it in cancer cells.

In 2001 researchers at the biotech giant Geron Corporation isolated a molecule called TA - 65 from the herb astragalus, which they said boosted telomerase activity (its effect has not yet been evaluated in published, peer - reviewed studies).
