CDH1 and breast cancer: Recent studies have demonstrated that the thyroid hormones triiodo-L-thyronine (T3) and tetraiodo-L-thyronine (T4) enhance EMT activity and the metastasis process via integrin αvβ3, reducing E-cadherin and increasing vimentin expression in ovarian cancer cells (6), but the action of T3 on EMT in BC cells remains to be determined.
