The top genes most correlated with induction one day after infection in the ‘brown2’ module included Gsta1, Uchl1, Cbr3, Gsta2 (A_51_P305138 feature), Gpx2, Srxn1, and Acox2. All of these genes are associated with oxidation/reduction and the response to oxidative stress, consistent with the ‘brown2’ modules ontologies from GOrilla [20] that included glutathione metabolic process (FDR-q value 6.3E-3) and response to oxidative stress (FDR-1 value 2.73E-2). The gene discussed is ACOX2; the disease is infection.
