Relative expression levels of critical genes involved in the inflammatory response. (a)–(c) Mean values with different letters on vertical bars indicate significant differences (P < 0.05). CON: pigs were fed with basal diet and challenged by sterile saline, SSY: pigs were fed with SeY-containing diet and challenged by sterile saline, DT: pigs were fed with basal diet and challenged by diquat, and DSY: pigs were fed with SeY-containing diet and challenged by diquat. TLR-4: Toll-like receptor 4; NF-κB: nuclear factor-κB; Nrf-2: nuclear factor erythroid-derived 2-related factor 2; HO-1: heme oxygenase-1.
