Perhaps a similar effect on Nb MYC expression, or effects on additional genes that directly impact Nb cell proliferation, enables azacytidine and ITF‐2357 to slow Nb tumor growth in p50(f/f);Lys‐Cre mice even though these agents did not further augment Nb tumor T‐cell activation; we will investigate this possibility in the future. The gene discussed is NFKB1; the disease is neuroblastoma.
