摘要 目的构建食管鳞癌组织与配对远癌旁正常食管组织的差异表达基因库。方法应用RNA测序技术及差异分析软件筛选并分析食管鳞癌与癌旁正常食管黏膜的差异表达基因库,通过Real-time PCR验证部分差异表达基因。结果应用RNA测序技术检测发现,食管鳞癌与配对癌旁正常食管组织间共142个(93个表达上调,49个表达下调)差异表达基因。其中,与增殖相关的基因16个(11个表达上调,5个表达下调);与细胞迁移功能相关基因9个(7个表达上调,2个表达下调);与细胞黏附相关基因12个(均表达上调);与血管生成功能相关基因2个(均表达上调);与凋亡相关基因6个(4个表达上调,2个表达下调)。通过Real-time PCR方法检测其中5个差异表达基因,证实癌及癌旁正常组织mRNA表达水平间差异有统计学意义,且上调或下调趋势与RNA测序结果一致。结论应用RNA测序技术成功构建食管鳞癌差异表达基因库,差异表达基因与肿瘤的增殖、迁移、黏附、血管生成及凋亡等生物学行为密切相关。
