We found that the top Gene Ontology (GO) and KEGG pathway terms were related to inflammation (Figures 2(a) and 2(b)), such as positive regulation of interleukin-1 beta production, inflammasome complex, NOD-like receptor signaling pathway, and C-type lectin receptor signaling pathway, indicating that the DEPRGs may participate in PAAD via immune regulation. This evidence concerns the gene IL1B and pancreatic adenocarcinoma.
