Abstract:

目的检测跨膜蛋白16A(TMEM16A)在口腔癌前病变组织及口腔鳞癌组织中的表达与分布情况,分析其在口腔癌变机制中的作用。方法采用免疫组织化学染色法检测10例正常黏膜组织、10例上皮单纯性增生、30例上皮异常增生和45例口腔鳞癌标本中TMEM16A的表达情况。结果TMEM16A在正常黏膜组织上皮中为阴性表达,在口腔癌前病变组织出现不同程度的表达,且随着上皮异常增生程度增加,TMEM16A蛋白表达逐渐增强。TMEM16A在口腔鳞癌中表达显著高于口腔癌前病变,在口腔鳞癌I、II、III级中,TMEM16A的表达差异无统计学意义(χ2=1.74,P>0.05)。结论TMEM16A在不同级别口腔癌前病变及鳞癌中表达的差异提示其可能在口腔鳞癌发生早期有重要作用。
