The up-regulated differential proteins were mainly centered on the changes of metabolic pathway, like amino acid biosynthesis, glucose metabolism, nucleotide metabolism, glutathione metabolism, and p53 pathway, etc. The down-regulated proteins were mainly concentrated on the pathway of amino acid degradation, mTOR signaling pathway, PI3K-Akt signaling pathway, O-glycan biosynthesis, etc. Among these DAPs, the expressions of classical tumor related signaling pathway p53 were up-regulated and the EGFR/mTOR pathway were down-regulated. Here, EGFR is linked to neoplasm.
