Interestingly, metabolic pathways, peroxisome proliferator activated receptor (PPAR) signaling pathway, cancer pathway, human T lymphotropic virus type-I (HTLV-I) infection, and cyclic guanosine 3′,5′-monophosphate (cGMP-PKG) signaling pathway were significantly overrepresented (Figure 5(b), Supplementary Table S6). The gene discussed is PPARA; the disease is cancer.
