A new study led by researchers at the University of Pittsburgh (Pitt) and UPMC Hillman Cancer Center has shown that an enzyme called PARP1 is involved in the repair of telomeres, the lengths of DNA ...

(THE CONVERSATION) A defining characteristic of cancer cells is their immortality. Usually, normal cells are limited in the number of times they can divide before they stop growing. Cancer cells, ...

New findings describe how the enzyme CST is recruited to the end of the telomere, where it maintains telomere length with the help of subtle chemical changes made to the protein POT1. The length of ...

Researchers at the University of Wisconsin–Madison have described the way an enzyme and proteins interact to maintain the protective caps, called telomeres, at the end of chromosomes, a new insight ...

A new study led by University of Pittsburgh and UPMC Hillman Cancer Center researchers shows that an enzyme called PARP1 is involved in repair of telomeres, the lengths of DNA that protect the tips of ...

Studies have reported that telomeres consisting of repeated DNA sequences (TTAGGG) play an essential role in protecting the human chromosome ends from fusions and degradation. Replication of cells ...

Imagine your DNA as a set of shoelaces. Telomeres are like the plastic tips at the ends of those shoelaces, preventing them from fraying and unraveling. Structurally, telomeres are repetitive ...

Transposons are critical drivers of bacterial evolution that have been studied for many decades and have been the subject of Nobel Prize winning research. Now, researchers from Cornell University have ...

CST (purple/lavender) bound to POT1 (red). Phosphorylation of the crimson-highlighted region in POT1 regulates the recruitment and activity of CST–Polα-primase at telomeres. The length of telomeres ...
