Telomeres are the ends of chromosomes, which protect the complex from DNA damage during cell division. The shortening of telomeres is considered an indicator of cellular aging, and prematurely shortened telomeres have been linked to an increased risk of cancers, heart disease, dementia and death.

David C. Zappulla, of Johns Hopkins University (Maryland, USA), and colleagues, have found evidence of such a biochemical process controls the length of the tips of the chromosomes, a potentially significant step in the final analysis, to understand the development of cancer and aging. The researchers observed that in cells of yeast, two proteins - and Ku Sir4 - work together to create the telomerase - an enzyme key to the telomeres, to restore its length.

The team hopes that their findings regarding the operation of this network of proteins capable of promoting telomerase might facilitate the understanding of aging and the process of cancer formation - in which telomerase plays an important role.
