Heterogeneous cadherin expression is a hallmark of EOC tumors, with cells expressing epithelial (E-) cadherin, mesenchymal neural (N-) cadherin, both E- and N-cadherin in the same tumor (‘mixed’ cadherin phenotype), and both E- and N-cadherin in the same cell (‘hybrid’ cadherin phenotype) (Hudson et al., 2008; Klymenko et al., 2017a,c). Here, CDH2 is linked to neoplasm.
