KEGG analyses showed that the 100 DEPs were mainly involved in ErbB signaling pathway, MAPK signaling pathway, PI3K-Akt signaling pathway, apoptosis, AMPK (AMP-activated protein kinase) signaling pathway, mTOR signaling pathway, etc. Among these, ErbB signaling pathway and apoptosis were more related with cancer. The gene discussed is EGFR; the disease is cancer.
