目的:探讨ADAR1 mRNA在肝细胞肝癌(HCC)及癌旁组织的表达及意义。方法:采用半定量逆转录-聚合酶链反应(RT-PCR)分别检测诊断为HCC41例患者的肝癌及癌旁组织RNA编辑酶ADAR1 mRNA的表达。结果:所有肝癌组织RNA编辑酶ADAR1均有表达,相对表达量为3.340±0.863;所有癌旁组织有RNA编辑酶ADAR1表达,相对表达量为0.801±0.209;对照的26例正常肝组织及其他肝脏疾病标本RNA编辑酶ADAR1的相对表达量为0.880±0.226。将肝癌组织和癌旁组织的ADAR 1mRNA表达量进行成组t检验,两者间存在显著性差异(t=18.30,P〈0.001);肝癌组织和对照肝组织的ADAR1 mRNA表达量进行成组t检验,两者问亦存在显著性差异(t=17.65,P〈0.001);将癌旁组织和对照肝组织检测到的ADAR1 mRNA的表达量进行成组t检验,两者间差异无统计学意义(t=1.64,P〉0.10)。将从同一患者取材的肝癌组织和癌旁组织的ADAR1 mRNA表达量进行配对t检验,两者问存在显著性差异(t=18.53,P〈0.001)。结论:ADAR1 mRNA在肝癌组织的表达增高,可能在肝癌的发生机制中起一定的作用。
Objective :To investigate the expressions of RNA - dependent adenosine deaminase 1 ( ADAR1 ) mRNA in hepatocellular carcinoma (HCC) tissues, and to discuss their value in the development of HCC. Methods: Using semi - quantitative reverse transcription polymerase chain reaction ( RT - PCR), we detected the expressions of A- DAR1 mRNA in the tissues of 41HCC,41 peri - HCC tumor samples and 26 non - HCC liver tissue samples from the patients. Results: ADAR1 mRNA expressed broadly; the relative intensities of its expression in HCC, peri -HCC tumor samples, non - HCC liver tissue samples were respectively 3. 340 ± 0. 863, 0. 801 ± 0.209, and 0.880 ± 0. 226. Condusion:ADAR1 mRNA expressed broadly in HCC and may be play an important role in the development of HCC.
