Among the tested genes, the expression of Il‐1 family Il1b and Il18, but not Tnf or Il6, were significantly increased in DCs that were cocultured with the Arf1‐ablated tumor cells (referred to as Arf1‐ablation‐stimulated DC) in comparison with those in DCs that were cocultured with the Scramble‐ablated control tumor cells (refer to as control DC; Figure S1c,d, Supporting Information). The gene discussed is IL18; the disease is neoplasm.
