PPARA and cancer: Our GSEA demonstrated that high TLR-based RS was distinct in relation to apoptosis, cell cycle, epithelial cell signaling in Helicobacter pylori infection, oocyte meiosis, pathway in cancer, and spliceosome, while low TLR-based RS was related to metabolism cytochrome P450; fatty acid metabolism; glycine, serine, and threonine metabolism; PPAR signaling pathway; and primary bile acid biosynthesis.
