In all, the 25 highest scored antibodies for PDAC versus NPC represented 20 nonredundant markers, including cytokines and chemokines (IL-11, IL-6, IL-13, IL-8, TNF-α, and Eotaxin), complement components (C1 inhibitor, C1q, C5, and Factor B), and enzymes (HADH2, GAK, and ATP-5B). This evidence concerns the gene IL11 and nasopharyngeal carcinoma.
