Abstract： 目的:检测肝癌组织中14-3-3基因家族成员表达差异的临床意义.方法:用TRIzol一步法提取肝癌组织、硬化肝组织及正常肝组织的总RNA并纯化mRNA.逆转录合成荧光分子(Cy3/Cy5)标记的cDNA探针与含有14-3-3基因家族成员的基因芯片杂交,用GenePix Pro3.0图像分析软件分析不同病变肝组织中该基因家族成员的表达差异,行半定量RT-PCR对结果进行验证并探讨差异表达基因的临床意义.结果:在肝癌组织中14-3-3基因家族成员呈差异表达,其中14-3-3γ在肝癌组织中明显下调,与肿瘤包膜的完整性相关.14-3-3η在肝癌组织中明显上调,与肿瘤患者的临床分期相关.14-3-3γ与14-3-3ηmRNA的表达强度呈负相关(r=-0.403,P＜0.05).结论:14-3-3基因家族调控机制的紊乱参与肝癌的发生、发展,其中14-3-3γ和14-3-3η与肝癌的关系最为密切.
