DNA accessibility sites requiring SMARCA4 activity in neuroblastoma cells [ATAC-seq]

To reveal the genome-wide targets of SWI/SNF complexes in neuroblastoma cells, we performed ATAC-seq in IMR-32 cells with or without SMARCA4 inactivation. To identify changes in DNA accessibility following SMARCA4 inactivation, we used either the small-molecule catalytic inhibitor BRM014, auxin-induced degradation of IMR-32 cells engineered with SMARCA4 tagged to the minimal auxin-induced degron (SMARCA4-mAID), or the corresponding vehicle controls. Analysis of these locations reveal that SMARCA4-dependent sites are located at enhancers used by the neuroblastoma core regulatory circuitry. ATAC-seq in neuroblastoma cells
