Therefore, the positive rate of cells co‐expressed with MUC5AC and MUC2 was used to classify the tumors, and the correlational analysis revealed a higher positive correlation between NOTCH3 and SMARCA4 in CRC patients with the high co‐expression of MUC5AC and MUC2 when compared with the low co‐expression of MUC5AC and MUC2 (Fig. 7E,F). Here, SMARCA4 is linked to colorectal carcinoma.
