Abstract: 目的 检测叶酸受体α(FRα)在各型垂体腺瘤和正常腺垂体中的表达情况;寻找对无功能垂体腺瘤(NFPA)诊断及其侵袭性判断具有重要意义的分子生物学指标.方法 收集垂体腺瘤组织标本44例和正常腺垂体组织3例,利用免疫荧光共聚焦,实时定量反转录(real-time RT-PCR)方法检测FRα在各标本中的表达.结果 FRa仅在NFPA中特异性表达,在其他类型的垂体腺瘤和正常腺垂体中不表达,差异具有统计学意义(P<0.01);FRa的表达水平与NFPA侵袭性存在显著相关性(P<0.05).结论 FRα可能在NFPA的发生发展中起到重要的作用;同时FRα可能作为NFPA特异性的诊断指标,为肿瘤的靶向诊治提供理论基础.
