Gene set enrichment analysis (GSEA) illustrated that the common enriched Hallmark sets between cells and tumours were associated with cytokine or chemokine‐related signalling pathways (such as NF‐κB and IL6/JAK/STAT3 pathway), apoptosis, and epithelial mesenchymal transition (Figure 2C). The gene discussed is NFKB1; the disease is neoplasm.
