Figure 6:

Annotated, enriched KEGG pathway. (A) Annotated KEGG pathway of phagosome. Genes in blue frames with red borders were up-regulated, genes in blue frames with yellow borders were down-regulated, and genes in blue frames with sky-blue borders were simultaneously up-regulated and down-regulated. (B) Annotated KEGG pathway of oxidative phosphorylation about DEGs. Genes in blue frames with white borders were differentially expressed in the pathway.
