GO results showed that TMEM170B is involved in leukocyte migration and cell–cell junction, whereas KEGG and GSEA indicated that TMEM170B is closely associated with immune-related pathways, cytokine–cytokine receptor interaction, chemokine signaling pathway, and T and B cell receptor signaling pathways in PAAD. The gene discussed is TMEM170B; the disease is pancreatic adenocarcinoma.
