摘要 目的探讨癌性抑制因子(CIP)2A和(c-Myc)在老年胶质瘤组织中的表达并分析两者表达的相关性。方法运用免疫组化技术检测CIP2A和c-Myc在52例老年胶质瘤和12例正常脑组织中的表达情况,分析CIP2A和c-Myc与胶质瘤组织学分级的相关性以及两者表达的相关性。结果 CIP2A和c-Myc蛋白在老年胶质瘤组织中的阳性率分别为65.4%(34/52)和59.6%(31/52),而两者在正常脑组织中的阳性率差异显著〔16.7%(2/12)和25.0%(3/12),χ2=9.403,P=0.002;χ2=4.691,P=0.030〕。CIP2A和c-Myc蛋白表达与肿瘤组织病理分化显著相关(χ2=4.544,P=0.033;χ2=5.369,P=0.020)。Pearson相关分析结果显示老年胶质瘤组织中CIP2A与c-Myc蛋白表达呈显著正相关(r=0.613,P=0.005)。结论老年胶质瘤组织中CIP2A高表达与肿瘤组织病理分化密切相关,并与c-Myc蛋白表达呈显著正相关,提示CIP2A可能通过稳定癌蛋白c-Myc促进老年胶质瘤发生发展。
