摘要 目的拟建立牙釉质细胞型颅咽管瘤的基因表达谱,筛选差异表达基因,并进一步分析差异表达基因与牙釉质细胞型颅咽管瘤的关系。方法采用含有16 450个Unigene的cDNA微阵列分析牙釉质细胞型颅咽管瘤组织与正常垂体柄组织表达谱的变化,应用实时荧光定量PCR技术验证cDNA微阵列检测出差异基因的可靠性,分析牙釉质细胞型颅咽管瘤组织相关基因的差异表达。结果2倍以上的差异表达基因453条,表达增加195条,表达减少258条。随机选择5条基因做RT-PCR验证,发现ADAMDEC1、CGA、HBG2及TRPM2基因在牙釉质型颅咽管瘤组织中存在表达异常。结论初步筛选出牙釉质细胞型颅咽管瘤异常表达基因。
