PPARA and cancer: KEGG pathway analysis indicated that the DEGs were highly associated with the peroxisome proliferator-activated receptor (PPAR), phosphoinositide 3-kinase (PI3K-) Akt, interleukin- (IL-) 17, and Wnt signaling pathways and extracellular matrix- (ECM-) receptor interaction, which have been confirmed to be involved in cancer initiation and progression (Figure 6(c)) [22–26].
