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 ...

Telomere is a repeated sequence (TTAGGG)N that caps the end of the chromosomes to protect them from damage during DNA replication prior to cell division. Telomere length is essential to the cell's ...

Our genome is organized into chromosomes, which are shaped like little X's. Every time a cell divides, the genome has to be replicated, and there are protective caps called telomeres on the ends of ...

A new study shows that an enzyme called PARP1 is involved in repair of telomeres, the lengths of DNA that protect the tips of chromosomes, and that impairing this process can lead to telomere ...

One protein appears to play an integral role in protecting telomeres, and possibly preventing cancerous growth, according to a study published this week in Science. Chromosomes with fluorescently ...

Each time a cell divides, a small section of each chromosome’s protective cap — the telomere — is worn away. Most cells use an enzyme called telomerase to help mitigate this loss, but 10% to 15% of ...

New Delhi | Stress, ageing, cancer. There are still no magic solutions but one factor linking all three holds out hope. And ...

A day in the life of DNA can be rough. It gets yanked across a dividing cell, zapped by radiation, and assaulted by chemicals. Luckily, cells have developed a complex set of repair mechanisms to ...
