NFKB1 and infection: 43 unique GO terms, 36 unique KEGG pathways and 154 GSEA sets were identified for all modules (Supplementary Data Sets DS4, DS5 and DS6), including modules that are enriched for chemotaxis, transfer of antigenic peptides (TAP) complex, apoptosis and NFκB regulation, all relevant to the strategies employed by F. tularensis upon infection of the cell (see further discussion below).
