Abstract

Aerobic exercise induces many adaptive changes in the whole body and improves metabolic characteristics. Klotho, an anti‑aging gene, is mainly expressed in the brain and kidney. The roles of Klotho in the brain and kidney during aerobic exercise remain largely unknown. The present study aimed to determine whether aerobic exercise could influence the expression of Klotho, decrease reactive oxygen species (ROS) and prolong life span. Sprague Dawley rats were exercised on a motor treadmill. Klotho mRNA and protein expression levels in rat brain and kidney tissues were examined using reverse transcription‑quantitative polymerase chain reaction and western blotting, respectively. ROS production was detected following intermittent aerobic exercise (IAE) or continuous aerobic exercise (CAE). Kaplan‑Meier curve analysis demonstrated that aerobic exercise significantly improved rat survival (P<0.001). The ROS levels in rat brain and kidney tissues were decreased in the aerobic exercise groups compared with the control group (P<0.05). In addition, Klotho mRNA and protein expression levels were increased significantly following aerobic exercise compared with controls (P<0.05). There was no significant difference between the IAE and CAE groups in any experiments (P>0.05). These results suggest that aerobic exercise‑stimulated Klotho upregulation extends the life span by attenuating the excess production of ROS in the brain and kidney. As Klotho exhibits a potential anti‑aging effect, promoting Klotho expression through aerobic exercise may be a novel approach for the prevention and treatment of aging and aging‑related diseases.
