The results of quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR) analysis of selected genes. The expression of Il1β, Il18, and Tnfα at 2 and 8 h was significantly higher in layer 1 and 4 groups than in layer 2 and 3 groups (P < 0.05). The expression of Il1β and Tnfα at 24 h was significantly higher in layer 1 and 4 groups than in layer 2 and 3 groups (P < 0.05)
