摘要
目的:探讨子宫内膜腺癌组织中HER-2/neu、COX-2、PGE_2、P450arom4种生物学指标的表达,分析这4种生物学指标表达强度之间相关性及与临床病理因素的相关性。方法:应用逆转录-聚合酶链反应(RT-PCR)技术及酶联免疫吸附试验(ELISA)检测HER-2/neu、COX-2、P450arom及PGE_2在正常子宫内膜、子宫内膜不典型增生和子宫内膜腺癌组织中的表达情况。结果:HER-2/neu、COX-2、P450arom及PGE_2在癌组织中表达高于非癌组织,有显著性差异(P<0.01)。癌组织中HER-2/neu与COX-2、P450arom表达强度呈正相关(r值分别为0.931,0.934,P<0.05),COX-2与P450arom表达强度亦呈正相关(r=0.908,P<0.05)。COX-2mRNA和PGE_2表达强度变化呈正相关(r=0.552,P<0.05)。结论:HER-2/neu、COX-2、P450arom及PGE_2可能存在协同作用,共同促进子宫内膜腺癌的发生发展。
Objective: To discuss the expression of four biological parameters, namely, HER-2/neu, COX-2, PGE2, andP450arom, in endometrial carcinoma as well as to analyze their relationship in the expression patterns and all kinds of clinicopathologic factors. Methods: Reverse transcription polymerase chain reaction and ELISA were used to detect the expression of HER-2/neu, COX-2, P450arom, and PGE2 in normal endometrium, endometrial hyperplasia, and endometrial carcinoma. Results: The expression levels of HER-2/neu, COX-2, P450arom, and PGE2 were significantly higher in tumorous tissue than in nontumorous tissue ( P 〈 0.01 ). There was a positive correlation among the expression levels of HER-2/neu, COX-2, and P450arom in the tumor ( r = 0.931, r = 0.934, P 〈 0.05 ). COX-2 expression was positively correlated with that of P450arom in tumorous tissue ( r =0.908, P 〈 0.05 ). There was also a correlation between the expression of COX-2 mRNA and PGE2 in the tumor ( r = 0.552, P 〈0.05 ). Conclusion: HER-2/neu, COX-2, P450arom, and PGE2 may have a synergistic effect on the oncogenesis and progression of endometrial adenocarcinoma.
