The relationship within the expression of p21~(WAF1/CIP1) 、Cyclin D_1、p53 in gastric carcinoma

  • 摘要: 目的 探讨p2 1WAF1/CIP1、细胞周期素D1(cyclinD1)、p5 3在胃癌中表达之间的相关性。 方法 应用原位杂交技术检测p2 1WAF1/CIP1mRNA、细胞周期素D1mRNA及免疫组化技术检测p5 3蛋白在胃癌中的表达。结果 p2 1WAF1/CIP1mRNA在癌组织及癌旁正常粘膜中阳性表达率各为 93.15 % (6 8/73)及76 .71% (5 6 /73), 二者相比具有显著差异 (P <0 .0 5 )。CyclinD1mRNA在癌组织及癌旁正常粘膜中阳性表达率各为 5 4 .79% (40 /73)及 30 .16 % (2 2 /73), 二者具有显著差异 (P <0 .0 5 )。p5 3蛋白在胃癌中的阳性表达率为 32 .87% (2 4 /73), p5 3过表达者, 其 p2 1WAF1/CIP1mRNA表达较p5 3阴性者为低, 二者存在显著差异 (P <0 .0 5 )。p2 1WAF1/CIP1表达与细胞周期素D1表达呈负相关。结论 p2 1WAF1/CIP1、CyclinD1、p5 3的异常表达及它们之间可能存在的相互作用, 对于胃癌的发生发展具有重要意义。

     

    Abstract: Objective To investigate the relationship within the expression of p21 WAF1/CIP1 、Cyclin D_1 and p53. Methods Hybridyzation in situ and immunohistochemical techniques were used. Results The positive rate of p21 WAF1/CIP1 mRNA in gastric carcinoma and normal mucosa was 93.15% and 76.71% respectively and was signficantly different ( P < 0.05 ). The positive rate of Cyclin D_1 mRNA in gastric carcinoma and normal tissue was 52.05% and 30.16%, and also was significantly different ( P <...
