As showed in Figure 5A, determination of inflammatory cytokines in muscle tissues from each group demonstrated that the level of IL-6 (Figure 5A, #p < 0.05 vs Control group) and TNF-α (Figure 5B, #p < 0.05 vs. Control group), as well as IL-1β (Figure 5C, #p < 0.05 vs. Control group) were obviously increased in the muscle of Tumor group, while were attenuated in that of Swimming group (Figures 5A–C; *p < 0.05 vs. Tumor group). This evidence concerns the gene IL1B and neoplasm.
