Estrogen receptor-β expression in laryngeal carcinoma: correlation with the expression of epithelial-mesenchymal transition specific biomarkers / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To detect the expression of ERβ in laryngeal carcinoma and the its correlation with the expression of epithelial-mesenchymal transition(EMT) specific biomarkers.@*METHOD@#Picture MT-Pv9000 was used to detect ERβ and EMT in 72 cases of human aqueous laryngeal carcinoma and 8 cases of adjacent non-neoplastic laryngeal mucosa by immunohistochemistry.@*RESULT@#The positive rates of ERβ in tumors and adjacent non-neoplastic laryngeal mucosa were 27.78% and 25.00%, respectively. The differences were not significant (P > 0.05). The abnormal expression rates of E-cadherin and β-catenin were 61.11% and 76.39% respectively. The expression of ERβ correlated negatively with the loss of E-cadherin, nuclear translocation of β-catenin and increased TNM stage. The differences were significant (P < 0.05).@*CONCLUSION@#The positive expressions of ERβ suggest a good prognosis in the differentiation, clinical stages and lymphatic metastasis of the laryngeal carcinoma. The underlying mechanism may be related with the abnormal expressions of E-cadherin and β-catenin.
