NFKB1 and infection: Herein, we have investigated the relationship between nutrition and immunity in Nv by 1) characterizing global gene expression changes in response to starvation, 2) assessing susceptibility to infection with a bacterial pathogen after starvation, 3) characterizing NF-κB after starvation by Western blotting, DNA-binding activity, and immunostaining, and 4) using Weighted Gene Correlation Network Analysis to explore relevant gene–gene interactions.
