KEGG enrichment analysis showed that 20 genes were significantly enriched (p-value < 0.05) in seven pathways (Table 2), including sulfur metabolism (ssc00920), neuroactive ligand-receptor interaction (ssc04080), protein export (ssc03060), butanoate metabolism (ssc00650), ErbB signaling pathway (ssc04012), colorectal cancer (ssc05210), and MAPK signaling pathway (ssc04010). Here, EGFR is linked to colorectal cancer.
