MUC2 and colorectal carcinoma: 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).
