摘要: 目的 着重探讨AEG-1和Caspase-3在三阴基底样癌组织中的表达及其相关性。方法 HE染色对66例检测对象的病理学诊断进行验证;免疫组化检测66例三阴基底样癌中AEG-1和Caspase-3的表达,分析其与临床病理参数的关系及二者的相关性。结果 66例检测对象均为三阴基底样癌;AEG-1和Caspase-3蛋白在三阴基底样癌组织中的阳性表达率分别为73%和60%;AEG-1在三阴基底样癌中的表达随着肿瘤分化程度的降低而增强,在血清学CA153阳性中的表达率显著高于阴性中的表达率,表达差异具有统计学意义(P<0.05);Caspase-3在三阴基底样癌中的表达随着肿瘤分化程度的降低而减弱,在血清学CA153阳性中的表达率显著低于阴性中的表达率,表达差异具有统计学意义(P<0.05);AEG-1和Caspase-3在三阴基底样癌组织中表达无相关性。结论 AEG-1和Caspase-3参与三阴基底样癌的发生和发展。但是AEG-1不能单独直接抑制Caspase-3的表达,可能与CA153相互作用,共同抑制Caspase-3的表达。

Abstract: Objective To prove AEG-1 and Caspase-3 expressions of basal-like cancer tissues and their relevance.Methods HE staining was used to verify the pathological diagnosis of cases.Immunohistochemistry was used to detect the expression of AEG-1 and Caspase-3 in 66 basal-like cancer.Results 66 cases were all basal-like cancer,respectively.The positive expression rates of AEG-1 and Caspase-3 were 73% and 60% in basal-like cancer,respectively.The expression of AEG-1 in basal-like cancer tissues increased with the reduction of the differentiation level,and significantly higher in basal-like cancer with CA153 high than that in basal-like cancer without CA153 high,(P<0.05).The expression of Caspase-3 in basal-like cancer tissues decreased with the reduction of the differentiation level,and was significantly lower in basal-like cancer with CA153 high than that in basal-like cancer without CA153 high(P<0.05).AEG-1 and Caspase-3 expressions in basal-like breast cancer tissues were negatively correlated,however it was not statistically significant(P>0.05).Conclusion AEG-1 and Caspase-3 maybe participate in progression of basal-like cancer.But,AEG-1 does not directly inhibit the expression of Caspase-3.It maybe interact with the CA153,as a cofactor in inhibiting the expression of Caspase-3.
