Figure 5: Serum level of pro-inflammatory cytokines for the 5 experimental groups: control, tumour, tum+FLX, tum+SSZ, tum+5-ASA/SP.

(A) FLX-treated mice had a significantly lower level of serum IL-1β compared to untreated tumour mice (P = 0.022). (B) Untreated tumour-bearing mice had higher levels of serum IL-6 compared to control mice (P = 0.015). (C) Serum IL-17A did not differ between any experimental groups. (D) Serum TNF-α did not differ between any experimental groups. Data are presented as mean ± SEM. Results were analyzed using one-way ANOVA. The Holm-Šidák correction was used to correct for multiple comparisons. *P < 0.05.
