Do telomeres shorten or lengthen?

Summary. Telomere length shortens with age. Progressive shortening of telomeres leads to senescence, apoptosis, or oncogenic transformation of somatic cells, affecting the health and lifespan of an individual. Shorter telomeres have been associated with increased incidence of diseases and poor survival.

Do telomeres get longer or shorter?

Every time a cell divides to reproduce, its telomeres get shorter. As Scientific American put it in 2009, “When they get short enough, our cells no longer divide and our body stops making those cells.” Over time, “this leads to aging and death,” the magazine noted.
