Effect of EP on the NF-κB and p38/MAPK signaling pathways in the small intestine. Intestinal tissue samples of the indicated groups were collected at 5 dpi. A Western blot analysis of proteins from jejunal and ileal tissues probed with the anti-p-IκBα, anti-IκBα, anti-p-NF-κB p65, anti-NF-κB p65, anti-p-p38 and anti-p38 antibody. B–G. Results are presented as the ratio of target protein band intensity to β-actin band intensity. Data are presented as the mean ± SEM. *P < 0.05; **P < 0.01; ***P < 0.001.
