(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 ...

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 ...

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 ...

UCSF researchers have found that the spread of melanoma can be inhibited by suppressing telomerase, the enzyme active in cancer cell growth. Findings reported in the July 5 Proceedings of the National ...

Scientists at Children's Medical Research Institute (CMRI) have made a major discovery about cancer cells. This new ...

New research reveals a new role for the enzyme telomerase, which scientists thought was turned off in most normal adult cells, except in cancerous tumors where it promotes unlimited cell division. The ...

Researchers discovered a "missing link" within plants between humans and simple pond scum that could provide insight into how some organisms live for thousands of years, according to a study published ...

Scientists discovered that the protein RPA plays a critical and previously unconfirmed role in stimulating telomerase to ...

Stem cells involved in replenishing human tissues and blood depend on an enzyme known as telomerase to continue working throughout our lives. When telomerase malfunctions, it can lead to both cancer ...

Science has identified in the plant kingdom the “missing link” of cellular immortality between human and single-celled animals, according to a new study led by scientists from Arizona State University ...

Over-activation of telomerase in 90 percent of malignant tumors has made the unusual enzyme a prime target for drug development efforts Researchers at UC Santa Cruz have determined the structure of a ...
