Rats with AA-induced colitis showed a marked increase in the NFκB p-65 gene expression (Figure 6A), phosphorylated p-65/p65 ratio (Figure 6B) and IκBα gene expression (Figure 6C); they also showed a significant reduction in IκBα (Figure 6D) and Nrf2 (Figure 6E) protein content when compared with the normal control group. This evidence concerns the gene NFKB1 and colitis.
