1、乳腺浸润性导管癌中paxillin和caspase-3蛋白的表达及临床意义仲广生,李孟圈,苏静郑州大学第一附属医院乳腺外科,郑州450052摘要目的 探讨桩蛋白(paxillin)和天冬氨酸特异性半胱氨酸蛋白酶-3(caspase-3)在乳腺浸润性导管癌(IDC)中的表达及其与乳腺浸润性导管癌(IDC)患者临床病理因素的关系。方法采用免疫组化检测术中切除的原发性乳腺浸润性导管癌(IDC)和距癌灶约5cm处正常乳腺组织中桩蛋白(paxillin)和天冬氨酸特异性半胱氨酸蛋白酶-3(caspase-3)的表达,统计学分析两者间及其与乳腺浸润性导管癌(IDC)病理特征的关系。结果paxi
2、llin在IDC组的表达高于正常乳腺组织组,差异具有统计学意义(P<0.05);caspase-3在IDC组的表达低于正常乳腺组织组,差异具有统计学意义(P<0.05)。在IDC组中,paxillin的表达与HER-2状态相关,2种蛋白的表达与乳腺IDC的淋巴结转移及及组织学分级相关,2种蛋白在IDC中的表达呈负相关(r=-0.32、p=0.013)。结论桩蛋白(paxillin)和天冬氨酸特异性半胱氨酸蛋白酶-3(caspase-3)的的异常表达在乳腺浸润性导管癌(IDC)的发生、发展中可能起着重要的作用,且与乳腺浸润性导管癌(IDC)的浸润转移密切相关。关键词乳腺肿瘤;桩蛋白;
