Telomere Length in Epidemiology: A Biomarker of Aging, Age-Related Disease, Both, or Neither?
1 Jan 2013
Abstract excerpt
Telomeres are nucleoprotein caps flanking DNA. They are shortened by cell division and oxidative stress and are lengthened by the enzyme telomerase and DNA exchange during mitosis. Short telomeres induce cellular senescence. As an indicator of oxidative stress and senescence (2 processes thought to be fundamental to aging), telomere length is hypothesized to be a biomarker of aging. This hypothesis has been...
