Furthermore, Shan et al. showed that triple-negative human breast cancer cell line MDA-MB-231 treated with 1–3 μM of CdCl2 for 8 weeks resulted in the suppression of breast cancer prognostic marker ferroportin, increased intracellular iron concentration, promotion of cell proliferation and migration, and induction of EMT [58]. The gene discussed is SLC40A1; the disease is breast carcinoma.
