Additionally, KEGG enrichment analysis identified involvement in pathways such as neuroactive ligand‐receptor interaction, GABAergic synapse, sphingolipid metabolism, IL‐17 signalling and cytokine‐cytokine receptor interaction, suggesting these pathways' potential roles in the pathogenesis of HCC or its response to treatment (Figure 4C,D). Here, IL17A is linked to hepatocellular carcinoma.
