Despite their high lifetime energy expenditures, most birds can be characterized as long-lived homeotherms with moderately slow aging. A growing body of research confirms the prediction that birds have special adaptations for preventing aging-related oxidative and glycoxidative damage. Nonetheless, biogerontologists have been slow to develop avian laboratory models. A number of domestic poultry and...
We have investigated whether the average relative telomere length of lens epithelial cells (LECs) from brown Norway rats decreases with the age of the donor animal, and whether chronic caloric restriction (CR) of the rats delays the telomere shortening. Our previous studies have demonstrated that clonal proliferative potential of rodent LECs as well as the in vivo rate of DNA synthesis decreases with...
There is compelling evidence for the central role of oxidative damage in the aging process and for the participation of reactive oxygen species in tumor initiation and promotion. Caloric restriction (CR) or energy restriction retards age-associated increases in mitochondrial free-radical production and reduces the accumulation of oxidatively damaged cell components. CR has also been shown to slow...
