Here, we show that when MYCN-amplified neuroblastoma cells are treated with retinoic acid, histone H3K27 acetylation and methylation become redistributed to decommission super-enhancers driving the expression of PHOX2B and GATA3, together with the activation of new super-enhancers that drive high levels of MEIS1 and SOX4 expression. The gene discussed is GATA3; the disease is neuroblastoma.
