Abstract
Increased oxidative stress in adipocytes causes dysregulated expression of inflammation-related adipokines. We have examined the effects of exercise training on oxidative stress in rat white adipose tissue (WAT), especially focusing on inflammation-related adipokines. The levels of lipid peroxidation in WAT of exercise-trained (TR) rats were lower than those in control (C) rats. The content of manganese-containing superoxide dismutase in WAT of TR rats was increased as compared with those in C rats. In contrast, the expression of the NADPH oxidase NOX2 protein in WAT was downregulated by exercise training. Moreover, the levels of inflammation-related adipokines, such as tumor necrosis factor-alpha and monocyte chemoattractant protein-1, in WAT of TR rats were lower than those in C rats. The effects of exercise training were more remarkable in visceral WAT than in subcutaneous. These results suggest that exercise training decreases the expression of inflammation-related adipokines by reducing oxidative stress in WAT.Entities:
