The effect of resistance training with liposomal vitamin C on UCP1 and FIS1 expression in hepatocytes of elderly rats

Background: Aging can increase the risks of various liver diseases and act as an unfavorable prognostic factor and increase mortality. Therefore, this study aimed to investigate the effect of 8-week resistance training with liposomal vitamin C on the expression of UCP1 and FIS1 in hepatocytes of elderly rats. Material and Methods: The present study was an experimental study with a control group. Twenty-five male rats (Wistar) aged 24 weeks (280-320 g) were randomly divided into 5 groups; young control group, elderly + resistance training group, elderly + liposomal vitamin C group, elderly + resistance training + liposomal vitamin C group and old age control group. In the groups receiving liposomal vitamin C, liposomal vitamin C was administered daily based on kilograms of body weight. Results: UCP1 expression was significantly reduced in the elderly group compared to the young group (P=0.001). However, the expression of UCP1 in the elderly group + resistance training along with vitamin C consumption increased significantly compared to the elderly group (P=0.001). Also, FIS1 expression was significantly increased in the elderly group compared to the young group (P=0.001). However, the expression of FIS1 in the elderly group + resistance training with vitamin C consumption was significantly reduced compared to the young group (P=0.001). Results: Aging increases FIS1 expression and decreases UCP1 expression in rat liver tissue. However, resistance training with vitamin C decreases FIS1 expression and increases UCP1 expression in elderly rats
