摘要
目的:探讨p33ING1、p53基因蛋白在食管癌中表达的临床意义及其相互关系。方法:采用免疫组织化学S-P法检测65例食管鳞状细胞癌组织中p33ING1(inhibitorofgrowth,ING1)、p53基因蛋白的表达。结果:食管癌中p33ING1蛋白阳性表达率为64.62%,食管癌中p331NG1表达与肿瘤的浸润、淋巴结的转移及分化有关;p53在食管癌中表达率为61.54%,食管癌中p53表达与肿瘤的浸润、淋巴结的转移及分化有关。p33ING1和p53在食管癌中表达呈负相关。结论:p33ING1是抑癌基因,在食管癌的发生、发展中可能起重要作用。p33ING1与野生型p53基因相互协同、相互依赖,抑制细胞生长,促进凋亡。检测食管癌患者p33ING1的水平,对p53介导的基因治疗有重要意义。
