Methods： Immunohistochemical 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. Results： The 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）. Conclusion： The abnormal expressions of Beta-catenin, APC protein, c-myc and cyclin-D1 might be used to indicate the malignance transform of ovarian epithelial tumors.展开更多
目的研究Caveolin-1 m RNA及蛋白在食管癌及癌旁正常食管黏膜中的表达及其意义,进一步探讨Caveolin-1与食管癌组织中细胞周期素-D1(Cyclin-D1)、P16及临床病理学指标的相关性。方法收集食管鳞癌及对应癌旁组织标本90例,分别采用RT-PCR...目的研究Caveolin-1 m RNA及蛋白在食管癌及癌旁正常食管黏膜中的表达及其意义,进一步探讨Caveolin-1与食管癌组织中细胞周期素-D1(Cyclin-D1)、P16及临床病理学指标的相关性。方法收集食管鳞癌及对应癌旁组织标本90例,分别采用RT-PCR、免疫组化方法检测Caveolin-1 m RNA及蛋白的表达情况,进一步分析Caveolin-1与食管癌组织中Cyclin-D1、P16及临床病理学指标的相关性。结果 Caveolin-1 m RNA及蛋白在食管癌中的表达均高于食管癌旁组织中的表达(P<0.05),且Caveolin-1 m RNA的表达与Cyclin-D1和淋巴结转移有关。结论 Caveolin-1在食管癌中高表达,可能与食管鳞癌的发生、发展以及浸润转移有关。展开更多
