Additionally, an investigation studying ductal breast tumor (T47D) cells found that SLC39A6 (solute carrier family 39 member 6; gene ID: 25800) can significantly promote epithelial-to-mesenchymal transition (EMT) [21], which has been defined to be predictive for tumor response following neoadjuvant chemotherapy for breast cancer [22]. This evidence concerns the gene SLC39A6 and breast neoplasm.
