A KEGG pathway analysis of Control group and BPD group. B KEGG pathway analysis of Control group and BPD group. In the red box is specific expression KEGG pathways: IL-17 pathway). C Verification of the IL-17 pathway. The expressions of IL-17A and IL-6 and TNF-α in serum. D mRNA expression of IL-17A, IL-6 and TNF-α. Data are displayed as mean ± SEM, n = 6. * P < 0.05; ** P < 0.01; *** P < 0.001. The KEGG analysis from (www.kegg.jp/kegg/kegg1.html).
