Responses in DENV versus other respiratory infections. (A) Volcano plot of results of the contrast from the linear regression analysis of DENV infected versus all other respiratory virus infections. y-axis: -log₁₀ BH multiple testing adjusted p-values, x-axis: log₂ fold change. DEGs (absolute log-fold change > 1.5, corresponding to a log₂-fold change > 0.85; multiple testing adjusted p-value < 0.05) are colored red and the top 20 up- and down-regulated (by log-fold change) DEGs are labeled. Blue: genes with adjusted p-value < 0.05. (B) Gene expression levels of the top four most strongly up-regulated (by absolute fold-change) dengue virus specific DEGs versus all respiratory viruses. HISTH1B: H1.4 Linker Histone, Cluster Member, HIST1H3F: H3 Clustered Histone 7, HIST1H2BM: H2B Clustered Histone 14, HIST1H2AL: H2A Clustered Histone 16. IAV: influenza, ENV_RHV: enterovirus/rhinovirus, MPV: human metapneumovirus, DenV: dengue virus, other_vir: all other respiratory viruses, hlty_contr: healthy controls. (C) Heatmap of normalized expression levels of the top 50 most strongly regulated (by absolute fold-change) DEGs from the contrast of DENV infected patients versus all respiratory infections are presented. Values were scaled by row. red: up-regulated DEGs, blue: down-regulated DEGS. IAV, influenza virus; ENV_RHV, enterovirus/rhinovirus; MPV, metapneumovirus; PaInf, parainfluenza virus; RSV, respiratory syncytial virus; AdV, adenovirus; CMV, cytomegalovirus; EBV , Epstein-Barr virus; DENV, dengue virus. (D) Functional analysis using GO term enrichment for the DEGs from the contrast of DenV infected versus all other respiratory virus infections. Network of top 20 up-regulated pathways and associated genes. Red: up-regulated. (E) Functional analysis using GO term enrichment for the DEGs from the contrast of DENV infected versus all other respiratory virus infections. Network of top 20 down-regulated pathways and associated genes. Green: down-regulated. NS, not significant.
