Annual Review Of Medicine 44:419-429. Recent studies have shown that
chromosomes shorten as cells divide and become senescent. Also,
deletions in mitochondrial DNA increase markedly with advancing age,
presumably secondary to damage from oxygen radicals. Since host
defenses against environmental factors also become attenuated, the
molecular damage associated with aging may increasingly perturb normal
homeostasis and increase the susceptibility to disease and disability.
Such age-associated dysfunctions can be targeted and interrupted.
