Telomere Shortening is Associated with Species Aging
Maria Blasco’s team at the Spanish National Cancer Research Center CNIO recently published a study that shows the rate of telomere deterioration is closely related to the maximum life expectancy of animals.
Telomeres
Telomeres are repeating DNA segments at the ends our chromosomes. They serve two important functions: they protect our ends, preventing any genetic damage. And, they act as a clock to limit the number of divisions our cells can undergo. Hayflick’s limit is a fundamental defense against cancer. Telomere attrition, however, is a hallmark of aging that leads to cellular degeneration and other age-related diseases.
