PLAU and infection: Venn diagram analysis showed that among the common DGEs in the 3 h and 12 h infection groups compared with the control group, 11 differential genes were enriched in the NF-κB signaling pathway, including CXCL8, IL-1β, CCL4, IκBα, TNF, NF-κB, CFLAR, PTGS2, TRAF1, PLAU, and IL-1β2 (Figure 4B).
