Researchers find mechanism that regulates telomeres

The tips of chromosomes have structures called telomeres comparable to the plastic cover at the end of shoelaces. They work as a protective cap that prevents genetic material from unfolding and corroding. When telomeres do ...

How DNA repair can go wrong and lead to disease

We often come to an understanding of what causes a disease. We know, for example, that cancers are caused by mutations at critical locations in the genome, resulting in loss of control of cell growth. We know that the onset ...

Early stress in starlings found to lead to faster aging

(Phys.org) —A combined team of researchers from Newcastle University and the University of Glasgow, both in the U.K. has found that stress in young starlings can lead to shortened telomeres—which prior research has suggested ...

High food availability slows down cell aging

Hibernation has long been considered the secret behind the relatively long lifespan of the edible dormouse. However, a team of researchers from Vetmeduni Vienna has now shown for the first time that high food availability ...

A protein required for integrity of induced pluripotent stem cells

Cell reprogramming converts specialised cells such as nerve cells or skin cells towards an embryonic stem cell state. This reversal in the evolutionary development of cells also requires a reversal in the biology of telomeres, ...
