SMARCC1 and lung carcinoma: In contrast, investigations in mouse embryonic stem cells show an interaction between SMARCB1 and mSWI/SNF subunits ARID1A, SMARCA4, and SMARCC1, with no interaction observed with BRD9 [55], which contradicts our preliminary results in lung cancer cells, where we have suggested that SMARCB1 may interact with BRD9.
