摘要 目的:探讨MCM3蛋白在甲状腺肿瘤组织中的表达及其临床意义。方法:选择甲状腺肿瘤术后新鲜组织标本150例为研究对象,其中甲状腺乳头状癌50例和单纯结节性甲状腺肿50例,另选择同期单纯结节性甲状腺肿切除术中周边正常甲状腺组织50例。应用免疫印迹方法检测MCM3蛋白的表达,分析MCM3蛋白的表达与甲状腺肿瘤的临床病理特征的关系。结果:甲状腺乳头状癌中MCM3阳性表达明显高于单纯结节性甲状腺肿和正常甲状腺组织,且结节性甲状腺肿组织中MCM3蛋白表达也高于正常甲状腺组织。结论:MCM3异常表达与甲状腺肿瘤的发生密切相关,且MCM3蛋白的表达越高越提示为恶性肿瘤,从中反映MCM3蛋白可作为甲状腺癌恶性生物学行为的重要标记物之一。
