Interestingly, DRPI-PG1 tumours were more likely to be associated with basal-like phenotype (p = 0.024), high proliferation markers such as Ki67 (p = 0.032) and Top2A overexpression (p = 0.004) and epithelial-mesenchymal transition markers such as CK5/6 (p = 0.006), E-cadherin (p < 0.001) and P-cadherin (p = 0.018) levels. This evidence concerns the gene CDH1 and neoplasm.
