摘要 目的:检测WWOX(WW domain containing oxidoreductase)基因6—8外显子在良恶性胸水中的mRNA表达。探讨WWOX基因是否在恶性胸水的发生、发展中起重要作用,更为重要的是尝试WWOX基因6—8外显子mRNA检测可否作为良、恶性胸水鉴别重要指标。方法:收集恶性胸水56例,良性胸水20例,分别提取恶性胸水及良性胸水中的RNA;用逆转录-聚合酶链反应(RT—PCR)技术对76例良、恶性胸腔积液进行WWOX基因mRNA6-8外显子表达的检测;从恶性胸水及良性胸水沉淀物中提取的RNA经逆转录合成cDNA,再经PCR反应,用电泳直接检测cDNA的扩增产物。结果:在76例胸水标本中有39例PCR未能扩增出预期长度的DNA片段,其中56例恶性胸水中,39例(69.6%)标本未能扩增出WWOX基因6—8外显子片段,而相对应的20例良性胸水标本全部扩增出WWOX基因6—8外显子片段,两者相比较有显著性差异(χ^2=6.765,P〈0.05)。31例经胸水细胞学及胸水沉淀物病理确诊肺癌的样本均未能扩增出WWOX基因6—8外显子片段,而胸水细胞学及胸水沉淀物病理阴性,最后经胸膜活检证实肺癌的25例恶性胸水样本中有8例未能扩增出WWOX基因6—8外显子片段。结论:研究表明,位于16q23.3—24.1的WWOX基因在非小细胞肺癌中存在较高的6—8外显子转录本缺失率,提示WWOX基因可能在恶性胸水的发生、发展中起重要作用;WWOX基因6—8外显子转录本的丢失是恶性胸水的重要分子标志;WWOX基因6—8外显子mRNA检测可作为良、恶性胸水鉴别重要指标。 Objective: To detect the abnormal expression of WWOX (WVV domain containing oxidoreductase) exons 6-8 at mRNA level in human benign and malignant pleural effusion and to investigate the role of loss of WWOX exons 6-8 in the development of malignant pleural effusion. Methods: Deletion of WWOX exons 6-8 mRNA transcript was analyzed by reverse transcriptase-PCR technology. Results: Of the 56 malignant pleural effusion samples, 39 showed loss of WWOX exons 6-8 mRNA transcript (69.6%). This deletion was not detected in the 20 benign pleural effusion samples. Conclusion: VVVVOX gene may play an important role in the develepment of malignant pleural effusion, Detection of WWOX exons 6-8 mRNA may serve as a candidate molecular target for treatment of malignant pleural effusion and can be a promising index in differential diagnosis of benign and malignant pleural effusion.
