癌胚抗原信使核糖核酸(CEA mRNA)-癌胚抗原(CEA)系统是与肿瘤密切相关的细胞生物系统,CEA mRNA是指导合成CEA的模版,在肿瘤时呈现高度活跃表达状态。尤其是CEA mRNA可在多种肿瘤组织中活跃表达。近年来,检测CEAmRNA-CEA指标为良、恶性胸腔积液鉴别诊断、评判治疗肿瘤的疗效等提供了一个新方法。1 CEA mRNA-CEA系统的分子生物学特点 CEA mRNA是指导合成CEA的模版,其基因由2个基因组构成,均位于19号染色体上。由CEA mRNA直接指导合
Carcinoembryonic antigen messenger RNA (CEA mRNA) - Carcinoembryonic antigen (CEA) system is closely related to the tumor cell biological system, CEA mRNA is a guide to the CEA template, the tumor showed a highly active state of expression. In particular, CEA mRNA is actively expressed in a variety of tumor tissues. In recent years, detection of CEAmRNA-CEA indicators for the differential diagnosis of benign and malignant pleural effusion, the evaluation of the efficacy of treatment of tumor provides a new method. 1 Molecular biology of CEA mRNA-CEA system CEA mRNA is a template that leads to CEA. Its gene consists of two genomes, all located on chromosome 19. Directly bound by CEA mRNA
