Proinflammatory cytokine genes were predominately upregulated in ARDS mice. (A) Experimental design: RNA-Seq analysis to identify differentially expressed genes (DGEs) in ARDS mice. (B) Volcano plot displaying RNA-Seq results. (C) Heatmap of top 20 upregulated genes and top 10 downregulated genes in ARDS lung tissues. (D) Biological processes of DGEs revealed by gene ontology (GO) analysis. (E and F) Verification of 12 DGEs by RT-qPCR analysis (n = 3). (E) IL-1B, IL-6, IL-15, IL-18, TNFA, and IFNG. (F) S100A8, CtBP2, ICAM1, SPP1, FBN1, and SPSB1. **P < 0.01; ***P < 0.001
