摘要
目的 :探讨E 钙黏蛋白 (E cad)及其相关蛋白α 连接蛋白 (α cat)、β 连接蛋白 (β cat)的表达与大肠腺癌细胞增殖的关系。方法 :用S P免疫组化方法检测 5 1例大肠腺癌中E cad、α cat、β cat的表达 ,分析其表达状况与Ki6 7标记指数 (LI)的相关性。结果 :5 1例大肠癌Ki 6 7LI为 44 7± 18 8( x±s)。 3种蛋白正常表达组与减低表达组Ki6 7LI分别为 :5 2 7± 17 5 ,38 7±17 7(E cad) ;5 0 2± 19 3 ,40 9± 17 8(α 连接蛋白 ) ;49 2± 18 2 ,42 7± 18 9(α 连接蛋白 )。E cad表达与癌细胞Ki6 7LI呈正相关 (P <0 0 5 ) ,α cat、β cat表达则与LI无关 (P >0 0 5 )。 结论 :E cad可能参与大肠腺癌细胞增殖的调节
