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). The gene discussed is SNAI1; the disease is thyroid gland papillary carcinoma.
