The results of KEGG enrichment analysis revealed that the DEGs were mainly involved in the metabolic pathway, neuroactive ligand-receptor interaction, pathways in cancer, cyclic adenosine 3’, 5’-monophosphate (cAMP) signaling pathway, cytokine-cytokine receptor interaction, phosphoinositide 3-kinase (PI3K)—protein kinase B (AKT) signaling pathway, mitogen-activated protein kinase (MAPK) signaling pathway and ras signaling pathway (Fig. 2D). This evidence concerns the gene WNK2 and cancer.
