为了探讨肾癌中β环连蛋白（βｃａｔｅｎｉｎ）表达变化的原因，我们应用ＲＴＰＣＲ等方法对２６例肾癌患者βｃａｔｅｎｉｎ基因（ＣＴＮＮＢ１）的表达进行了研究。随机选择１９９６～１９９７年间本院肾癌手术标本２６例，病理证实为肾细胞癌；其中男性２０例... In order to explore the reason of the change of βcatenin expression in renal cell carcinoma, we used RTPCR method to study the expression of βcatenin gene (CTNNB1) in 26 patients with renal cell carcinoma. Randomly selected in our hospital from 1996 to 1997, 26 cases of renal cell carcinoma specimens, the pathology confirmed as renal cell carcinoma;
