Telomeres, the repetitive sequences of DNA at the ends of linear chromosomes, have an important function: They protect vulnerable chromosome ends from molecular attack. Researchers at Rockefeller ...

A new study by EPFL researchers shows how RNA species called TERRA muster at the tip of chromosomes. [EPFL / Demcon-Nymus3D] Molecules that accumulate at the tips of chromosomes are known to play a ...

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 ...

A new study in Molecular Cell shows that a single DNA damage sensor, ATM, fully controls telomere-driven cell aging and that ...

Find out what telomeres are and how to hack your DNA to slow down the aging process, from the authors of The Telomere Effect. When it comes to gracefully getting older, most women have a few regular ...

A new study suggests vitamin D supplements might slow cellular aging by protecting telomeres. Vitamin D supplements might slow cellular aging by preventing the loss of telomeres, DNA sequences at the ...

This new resource aims to change that by providing a detailed framework for understanding how different cancers maintain their telomeres and where their weaknesses lie.

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 ...

Many types of cells have to be replenished continuously throughout our lives, and the genome has to be duplicated and distributed to two new daughter cells during cell division. The genome is ...
