摘要 目的:应用基因芯片技术研究乳腺浸润性导管癌(invasive ductal carcinoma,IDC)基因表达的改变。方法:收集手术切除3例IDC癌组织及癌旁对应正常组织标本,提取总RNA,逆转录合成cDNA,用荧光素Cy3通过体外转录分别将6份标本的cDNA标记成cRNA探针,并与6张基因芯片Illumina Human WG-6 expression beadchip杂交,利用荧光扫描仪扫描荧光强度并分析基因表达谱的差异。结果:按差异显著性标准,在3对标本中共同差异表达的基因有6 756个,表达上调3 927个,表达下调2 829个。结论:IDC的发生、发展存在多基因表达调控的改变,基因芯片技术可同时定量研究大量基因表达水平,为认识肿瘤发病机制和个体化治疗提供生物学依据。
