The intestinal protein and mRNA expression of NF-κB and MAPK signaling pathways of NBW, CUG and NCUG piglets on 26 d. A Protein expression of P-JNK/JNK and P-NF-κB/NF-κB, mRNA expression of MAPK3, MAPK8, MAPK14 and NFKB1 in the duodenum. B Protein expression of P-JNK/JNK and P-NF-κB/NF-κB, mRNA expression of MAPK3, MAPK8, MAPK14 and NFKB1 in the jejunum. C Protein expression of P-JNK/JNK and P-NF-κB/NF-κB, mRNA expression of MAPK3, MAPK8, MAPK14 and NFKB1 in the ileum. Dates are presented as means ± SEM (n = 3 for protein expression; n = 4 for mRNA expression). NBW, normal birth weight. CUG, catch-up growth. NCUG, not catch-up growth. *P < 0.05; **P < 0.01
