摘要 目的观察Twist、E-cadherin在人脑神经胶质瘤及其复发灶中的表达情况,探讨Twist、E-cadherin表达与神经胶质瘤分级和复发之间关系。方法采用免疫组化SP法检测Twist、E-cadherin在52例神经胶质瘤及其相应复发灶、10例非肿瘤脑组织中的表达。结果 Twist在神经胶质瘤中的表达水平比对照组更高(Z=-3.80,P<0.01);Twist在高级别胶质瘤组织中的表达水平比低级别胶质瘤组织高(Z=-4.23,P<0.01);Ecadherin在低级别胶质瘤组织与高级别胶质瘤组织中的表达水平差异无统计学意义(P>0.05);Twist、E-cadherin在原发灶与复发灶中的表达水平差异无统计学意义(P>0.05);人脑胶质瘤中Twist的表达水平与E-cadherin的表达水平呈负相关(r=-0.57,P<0.01)。结论人脑神经胶质瘤的发生及演进过程可能与Twist表达上调及E-cadherin表达下调有关;Twist的表达水平与E-cadherin的表达水平呈负相关,提示Twist可能通过上皮向间质转化参与胶质瘤的演进。
