Extending telomere and cancer
WebAs cancer incidence abruptly increases during aging, cancer can be viewed as an aging-associated disease in which telomere shortening might play a significant role. Initially, telomere shortening was proposed as a tumor suppressor mechanism, being a limiting factor in the lifespan of human cells . Accordingly, cancer cells need to stabilize ... WebSep 16, 2013 · A small pilot study shows for the first time that changes in diet, exercise, stress management and social support may result in longer telomeres, the parts of chromosomes that affect aging. It is the first controlled trial to show that any intervention might lengthen telomeres over time. The study will be published online on Sept. 16 in …
