Papillary thyroid carcinoma is one of the most common subtypes of thyroid cancer and portends a good prognosis. N-cadherin (neural cadherin) is a member of the classical cadherin family and is often overexpressed in many types of cancers. Snail, a kind of zinc finger protein, is a transcriptional repressor which has been intensively studied in mammals. We investigate the immunohistochemical expression of Snail and N-cadherin in papillary thyroid carcinoma tissues and cells and then discuss the clinical value of Snail and N-cadherin expression. Immunohistochemical technique was performed to detect Snail and N-cadherin in 60 cases of papillary thyroid carcinoma and analyzed the relationship between the expression of Snail, N-cadherin, and clinicopathological indicators. Western blot was used to investigate the constitutive and inducible expression of Snail and N-cadherin. In our study, the expression rate of Snail and N-cadherin was 85.0
