In agreement, we found enhanced expression of the Snail family of EMT inducers (including Snail and Slug) and TGF-β1, TGF-β3, and TGF-βRII in the murine papillary thyroid carcinoma samples as shown in previous studies (13, 35, 44). This evidence concerns the gene TGFB3 and differentiated thyroid carcinoma.
