Fig 4. The relative expression levels of the pro-inflammatory and anti-inflammatory cytokine.

mRNA levels of pro-inflammatory and anti-inflammatory cytokines, including IFN-γ (A), Il-1β (B), Il-6 (C), Il-10 (D), CXCL10 (E), and TNF-α (F), were quantified from the colon tissue of each group of mice. Each mRNA level of cytokines was normalized with GAPDH, the reference gene. The data for each group is represented as the mean ± SEM. (n = 6–7) *P < 0.05; **P < 0.01; ***P < 0.001. (Kruskal-Wallis test).
