Methods： Immunohistochemical staining with SP method was conducted to identify the expression of Wnt-1, beta-catenin and c-myc in 18 samples of normal epithelial tissue and 34 cases of malignant epithelial tumor of ovary. Results： The expression rate of Wnt-1 and c-myc in malignant epithelial tumors was higher than those in normal epithelial cell （P〈0.05）. The abnormal expression rate of beta-catenin in malignant ovarian epithelial tumors was higher than that in normal epithelial cell （P〈0.05）. A significant positive correlation was found between Wnt-1, beta-catenin and c-myc in malignant ovarian epithelial tumor （P〈0.05）. A significant difference of expressions of Beta-catenin and C-myc was found between serous and mucinous tumors （P〈0.05）. Conclusion： The abnormal expression of Wnt-1, beta-catenin and c-myc might indicate the malignant transformation in ovarian epithelial tumors.展开更多
