Telomeres – which are the DNA repeats that form the tips of chromosomes and are produced by the telomerase enzyme – play a crucial, and curious, role in the life of the cell. While chromosomes are ...

A structural model of the telomerase enzyme shows how the binding domain (purple) tethers one end of the RNA component of the enzyme. (Image credit: Jansson et al., ) Researchers at UC Santa Cruz have ...

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 ...

Recent research has uncovered a fascinating mechanism in the nematode worm C. elegans that could have profound implications ...

Like a genetic handyman, an elusive enzyme deep inside certain cells repairs the tips of chromosomes, which fray as cells divide. It’s prized by rapidly dividing cells – like stem cells and tumor ...

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 ...

(PHILADELPHIA) – Inappropriate activation of a single enzyme, telomerase, is associated with the uncontrollable proliferation of cells seen in as many as 90 percent of all of human cancers. Since 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 ...

A study reveals that a protein called RPA is essential for maintaining chromosome stability by stimulating telomerase. New findings from the-Madison suggest that problems with a key protein that helps ...

Scientists at UC Santa Cruz have identified a key structural component of the telomerase enzyme that can contribute to cell proliferation in cancer cells, publishing their findings in Nature ...

Researchers at UC Santa Cruz have determined the structure of a key part of the enzyme telomerase, which is active in most cancers and enables cancer cells to proliferate indefinitely. The new ...
