SMARCA4 and cancer: To investigate if this might occur in BRG1-deficient tumors, we performed IHC for CARM1 (BRG1 and CARM1 are 70 kbp apart) in each of the 20 BRG1-deficient tumors for which we had matched frozen specimens (Table 2); we observed that CARM1 was robustly expressed in > 70% of the cancer cells in each of these 20 tumors (Figure 2 Panel A (BRG1) and Panel B (CARM1)).
