Moreover, the pathway overrepresentation analysis in the InnateDB (Breuer et al., 2013) identified the following top 5 overrepresented pathways (a corrected P value of < 0.05): hepatitis C, protein processing in endoplasmic reticulum, adipocytokine signaling pathway, peroxisome proliferator-activated receptor (PPAR) signaling pathway, and TLR signaling pathway. The gene discussed is PPARA; the disease is hepatitis C virus infection.
