The effects of interval aerobic training on mesenchymal biomarker gene expression, the rate of tumor volume, and cachexia in mice with breast cancer

Objective(s): It seems that regular exercise can have inhibitory effects on the progression of breast cancer. This study, therefore, aimed to investigate the influences of interval aerobic training on mesenchymal biomarker gene expression, muscle cachexia, and tumor volume changes in mice with breast cancer. Materials and Methods: Thirty-two female Balb/c mice were allocated to four groups: Exercise Tumor Exercise, Rest Tumor Rest (Control), Rest Tumor Exercise, and Exercise Tumor Rest. Interval aerobic training was done 6 weeks before and 4 weeks after tumor induction. Weight test and inverted screen test were carried out as muscle function tests. Data were analyzed using one-way ANOVA and HSD post hoc. Results: The results showed a significant decrease in gene expressions of Twist, Vimentin, and TGF-beta in Exercise Tumor Exercise group in comparison with the Control group (P
