Nonhuman primate rhesus monkey is a ideal model for human aging and aging intervention. Same with human aging, rehesus monkey demonstrates age-related aging and diseases in endocrine, neural, immune and cardiovascular system. Coloric restriction can slow down the primary and secondry aging efficently. The mechanism may be to suppress the oxidative stress-inflammaging-DNA damage by mediating the nutrient sensitive metablic signal pathways, and activate damaged DNA repair. However, the differeces of study design, husbandry and diet composition may differently affect CR against the the primary and secondry effects in a long-lived nonhuman primate. Optimization in protocol design, control of the experimetal variables, and shortening the experimental period will be advantageous to understand the mechanistic questions about the anti-aging effects of CR.
