Meanwhile, in the lower half of the plot, the viral infections related processes HPV (Tcf7, Fzd4, Itga4, Tcf7, Tnf, etc.)and HIV (Xpo1, Npm1, Nup50, Nup153, Nup160, Nup205, etc.), and the p53 signaling (Dusp5, Ddit4, Ccng1, etc.)are over-represented by downregulated genes (Figure 5C and Supplementary Table 5). The gene discussed is FZD4; the disease is viral infectious disease.
