PPARA and cancer: Pathway enrichment analysis indicated that these genes were mainly involved in a total of 32 pathways, such as olfactory transduction, neuroactive ligand-receptor interaction, pathways in cancer, MAPK signaling pathways, calcium signaling pathways, cytokine-cytokine receptor interaction, PPAR signaling pathways, GnRH signaling pathways, Wnt signaling pathways, Jak-STAT signaling pathways, Notch signaling pathways, fatty acid metabolism, and purine metabolism.
