Two pathways; “TNF signaling pathway” and “Pathways in cancer” were common to all with TNF signaling pathway being most robustly enriched (Benjamini ≤0.05) in HBE cells and airway tissue, and “Pathways in cancer” showing Benjamini ≤0.05 in BEAS-2B cells (Table 2). The gene discussed is TNF; the disease is cancer.
