Snail, Slug, and Smad‐interacting protein 1 as novel parameters of disease aggressiveness in metastatic ovarian and breast carcinoma

It was demonstrated previously that the Snail family of transcription factors and Smad‐interacting protein 1 (Sip1) regulate E‐cadherin and matrix metalloproteinase 2 (MMP‐2) expression, cellular morphology, and invasion in carcinoma. For the current study, the authors analyzed the relation between the expression of Snail, Slug, and Sip1; the expression of MMP‐2 and E‐cadherin; and clinical parameters in patients with metastatic ovarian and breast carcinoma.
