Telomeres are the tips of chromosomes (DNA), and they get shorter as we get older and cells divide. Telomerase is the enzyme that repairs these tips and has such potential to repair age or disease-related damage. Discovery of telomerase earned three biochemical researchers the Nobel Prize for Medicine. Elizabeth Blackburn, below, was one of the Nobel winners.
Telomerase and Hypertension
Mice deficient in telomerase activity develop hypertension because of an excess of endothelin production.
