Its expression was associated with axillary lymph node positivity in the set of 392 tamoxifen-treated ER-positive breast tumors (Table 2 in [105]) and its inhibition as well as siRNA knockdown led to reduced MCF7 cell migration and E-cadherin induction (Figures 1B, 2A,B and 3 in [106]). This evidence concerns the gene CDH1 and breast neoplasm.
