SOAT1 and pancreatic neoplasm: The functional classification of DEPs was conducted by KEGG enrichment analysis, and each protein was assigned to at least one of the following pathways: human T-lymphotropic virus-1 infection pathway (path: ko05166), cell adhesion molecules (CAMs) (path: ko04514), epidermal growth factor receptor tyrosine kinase inhibitor resistance (path: ko01521), Janus kinase-STAT signaling pathway (path: ko04630), and pancreatic cancer (path: ko05212) (Fig. 3C).
