Abstract
ObjectiveTo investigate the expressions of beta-catenin, protein APC (adenomatous polyposis coli protein), c-myc and cyclin D1 and their implication in ovarian epithelial tumor.MethodsImmunohistochemical staining with SP method was conducted to identify the expressions of beta-catenin, APC protein, c-myc and cyclin D1 in ovarian epithelial tumor in 48 cases.ResultsThe abnormal expression rate of beta-catenin in malignant and borderline ovarian epithelial tumors was higher than that in benign epithelial tumors (P<0.01). The expression rates of c-myc and cyclin-D1 in ovarian malignant and borderline epithelial tumors were higher than those in benign epithelial tumors too (P<0.05). The prevalence of APC protein positive expression in benign epithelial tumors were significantly greater than that in malignant epithelial tumors (P<0.05). A significant negative correlation was found between beta-catenin and APC protein in ovarian epithelial tumors; while a significant positive correlation was found between beta-catenin, c-myc and cyclin-D1 in ovarian epithelial tumor (P<0.05).ConclusionThe abnormal expressions of Beta-catenin, APC protein, c-myc and cyclin-D1 might be used to indicate the malignance transform of ovarian epithelial tumors.
