High expression of MUC1 competitively binds to β-catenin at cell junctions, dissociating the E-cadherin–β-catenin complex and upregulating the expression of EMT inducers, which leads to cytoskeletal destabilization of the intercellular adhesive junction rearrangement, reducing intercellular adhesion between cancer cells and promoting basement membrane invasion [56, 57]. Here, MUC1 is linked to cancer.
