摘要 目的检测胶质瘤患者术后组织中B细胞特异的莫洛尼白血病病毒插入位点(Bmi)-1、白细胞分化抗原(CD)147和抑癌基因PTEN(PTEN)的表达,研究三者在肿瘤中表达的差异。方法确诊的97例胶质瘤术后组织作为观察组,58例因脑血管畸形切除的正常脑组织作为对照组,应用免疫组化SP法检测两组中Bmi-1、CD147和PTEN的表达特点。结果两组中Bmi-1、CD147和PTEN表达的阳性率差别均有统计学意义。观察组中Bmi-1、CD147和PTEN的表达与肿瘤的最大径、分级、是否伴有坏死、Ki67的表达均具有相关性。线性相关分析显示Bmi-1、CD147和PTEN的表达均具有负相关性。结论胶质瘤术后组织Bmi-1和CD147高表达,PTEN低表达可以促进肿瘤的发生,同进可以促进肿瘤的进展,Bmi-1和CD147在发挥作用过程中可能对PTEN的表达有重要调节作用。
