Study shows how telomerase can run amok, deleteriously capping damaged DNA, were it not for a first responder to DNA damage. The natural ends of chromosomes appear alarmingly like broken DNA, much as ...

Telomerase is a ribonucleoprotein enzyme that maintains the protective structures at the ends of eukaryotic chromosomes, called telomeres. In most human somatic cells, telomerase expression is ...

Cancer, aging-related diseases and other illnesses are closely tied to an important enzyme called "telomerase." UCLA researchers report in the journal Cell the deepest scientific understanding yet of ...

Our DNA is organized into chromosomes, and the ends of chromosomes are protected with caps called telomeres; when cells divide, they lose a very small amount of DNA from those ends. Short telomeres ...

Researchers at Arizona State University’s (ASU) School of Molecular Sciences and the Biodesign Institute’s Center for the Mechanism of Evolution have discovered an unprecedented pathway producing ...

Of the many components in the cell thought to play a role in cancer, few have received more attention in recent years than an enzyme that has been dubbed a cellular fountain of youth. Known as ...

Researchers at the Salk Institute have discovered an on/off switch for telomerase, an enzyme that rebuilds a cellular timekeeper known as a telomere. The scientists believe that the discovery could ...

Researchers at the University of California, Berkeley have published the first detailed image of the molecular structure of human telomerase, the enzyme that lengthens chromosomes and extends the ...

New research from the University of Maryland and the National Institutes of Health reveals a new role for the enzyme telomerase. Telomerase's only known role in normal tissue was to protect certain ...

Although most of us accept aging as a natural part of life, it might not have to be. Researchers at UC Berkeley have now mapped out the structure of telomerase – an enzyme known to play a key role in ...
