A new study reveals the connection between dietary iron and cancer progression, paving the way for targeted therapies in ...

Scientists have uncovered the hidden danger of how high iron levels from red meat may increase the risk of colorectal cancer.

Researchers at The University of Texas MD Anderson Cancer Center have demonstrated that therapeutically restoring "youthful" ...

By restoring youthful levels of a key component of the telomerase enzyme, they have successfully reversed aging-related symptoms in laboratory models. If these findings translate to humans ...

Then, during the next round of DNA replication, DNA polymerase and the DNA repair enzymes fill in the other strand. Thus, telomerase is able to both maintain and extend the length of telomeres.

Key questions include how subunits of the telomerase enzyme contribute to activity, how the single-strand DNA overhang is shielded from the DNA-damage machinery, and whether capping activity also ...

Telomerase is an enzyme that can compensate for this shortening by maintaining telomeres at a stable length, helping to protect chromosomes against degradation and fusion. Mutations that ...

Many scientists are not sure what to think about potential extra-telomeric functions for telomerase. But it is hard to understand why the enzyme activity would go up so dramatically, and in our case, ...

The three were honored for “for the discovery of how chromosomes are protected by telomeres and the enzyme telomerase.” According to the Royal Swedish Academy, this year’s Nobel Prize in Physiology or ...
