It was revealed that the DEmRNAs between BC and normal breast tissues were significantly enriched in focal adhesion (hsa04510), PPAR signaling pathway (hsa03320), ECM-receptor interaction (hsa04512), PI3K-Akt signaling pathway (hsa04151), axon guidance (hsa04360), and pathways in cancer (hsa05200). Here, PPARA is linked to cancer.
