摘要 目的研究鼻咽癌组织中X连锁凋亡抑制蛋白(XIAP)与其拮抗蛋白Smac/DIABLO的表达及其意义。方法以50例鼻咽癌患者鼻咽部活体组织石蜡标本和20例鼻咽部慢性炎症组织石蜡标本为研究对象,利用组织芯片技术同时采用S-P免疫组织化学方法检测鼻咽癌组织芯片中XIAP和Smac/DIABLO的表达。结果 (1)鼻咽癌中XIAP的阳性表达明显高于鼻咽部慢性炎症组织,差异有统计学意义(P<0.05);鼻咽癌中Smac/DI-ABLO的阳性表达均明显低于鼻咽部慢性炎症组织,差异有统计学意义(P<0.05)。(2)Smac/DIABLO在XIAP阳性的鼻咽癌石蜡标本中的阳性表达率低于在XIAP阴性的鼻咽癌石蜡标本中,XIAP和Smac/DIABLO表达均呈明显负相关(P<0.05)。结论 XIAP在鼻咽癌中高表达,Smac/DIABLO在鼻咽癌中低表达,鼻咽癌中XIAP和Smac/DIABLO表达呈负相关。XIAP和Smac/DIABLO可能是鼻咽癌细胞凋亡信号传导网络中的重要一环,其与鼻咽癌的发生、发展密切相关。
