Splet04. dec. 2015 · Telomeres shorten throughout the human life span, including during the aging portion of life. In marked contrast, critical telomere shortening appears to be negligible during the normal aging of the mostly much more short-lived animal models used for laboratory studies of aging. Splet03. mar. 2024 · Researchers have long suspected that shortening telomeres are among the causes of aging. In adult tissues, there isn’t enough telomerase to keep up with cell division. Gradually, throughout the human lifespan, telomeres get shorter and shorter, and more and more cells enter senescence. Splet18. apr. 2024 · Telomeres' Relation to Aging and Cancer. Scientists can use the length of a telomere to determine the age of a cell and how many more replications it has left.
