As showed in Figure 3, compared with the NBW group, IUGR finishing pigs had significantly enhanced mRNA expression of IL-6, TNF-α and NF-κB (P < 0.05), and no significant differences in the mRNA expression of Nrf2, Keap1, HO-1, GCLC, GCLM, SOD1, GPx1, IL-1β, IL-4, IL-10 and IFN-γ (P > 0.05). This evidence concerns the gene IL10 and fetal growth restriction.
