Aims: Caloric restriction (CR) is an experimental approach proposed to alleviate age-related oxidative damage. In the present study, we investigated the consequences of CR on renal redox homeostasis in rats at a specific time frame in early-adulthood.. Methods: Three groups of male Sprague-Dawley rats; young control at 6-month-old, 2-year-old subjected to 40% CR between 18th-24th months of age, and their non-CR controls were sacrificed, and numerous redox status biomarkers including protein oxidation, glycation, lipid peroxidation, glycation end products, thiol groups, and superoxide dismutase were assayed. It was also ensured that CR rats and their non-CR corresponding rats had similar body weights at the end of the study to decrease the confounding effects of different body weights on redox homeostasis and caloric restriction. Results: After CR, the detrimental effects of the protein oxidation, glycation, and lipid peroxidation were significantly improved in the renal tissue CR rats when compared to their non-CR control group. However, there were no significant difference in thiol fractions between younger controls and both of the elderly groups. Conclusion: Detrimental consequences of renal senescence on redox homeostasis are significantly improved via CR especially applied in early-adulthood.
