摘要 目的应用基因芯片技术,筛选侵袭性与非侵袭性垂体腺瘤中存在表达差异的miRNA,预测其靶基因。方法收集侵袭性、非侵袭性垂体腺瘤组织样本各6例,利用miRNA芯片对其进行实验分析,运用实时荧光定量PCR验证其结果。结果部分miRNA在侵袭性垂体腺瘤中表达异常,其中显著上调的为hsa-miR-27b,hsa-miR-103,hsa-miR-30d,hsa-miR-23a,hsa-miR-92b和hsa-miR-126*。显著下调的为hsa-miR-34b,hsa-miR-1258,hsa-miR-634,hsa-miR-99a,hsa-miR-885-5p,hsa-miR-1246,hsa-miR-499b,hsa-miR-22,hsa-miR-21和hsa-miR-138-1*。实时荧光定量PCR验证结果与芯片检测结果一致。结论在侵袭性垂体腺瘤与非侵袭性垂体腺瘤中,部分miRNAs存在表达差异,这可能与垂体腺瘤的侵袭性生长有关。
