目的

探讨Ezrin 蛋白、诱导型一氧化氮合酶(iNOS)在黏液表皮样癌(MEC)中的表达以及在肿瘤侵袭转移过程中的作用。

方法

应用免疫组化SP 法检测36 例高分化MEC、24 例低分化MEC,以及正常唾液腺组织中Ezrin 蛋白、iNOS 蛋白的表达,结合临床资料进行Ezrin 蛋白、iNOS 蛋白表达与MEC 转移的相关性分析。

结果

Ezrin 蛋白、iNOS 在正常唾液腺组织、高分化MEC 及低分化MEC 中的表达均依次增强,差异均有统计学意义(P <0.05),而Ezrin 蛋白和iNOS 两者之间的表达也有相关性(P <0.01);Ezrin 蛋白与iNOS 的表达分别与MEC 肿瘤的转移有相关性(P <0.05)。

结论

Ezrin 蛋白和iNOS 之间存在密切关系,均与MEC 的转移高度相关。

Objective

To study the expression of Ezrin and inducible nitric oxide synthase(iNOS) in mucoepidermoid carcinoma (MEC) and the relationship between the positive rate of Ezrin, iNOS and MEC metastasis.

Methods

The expression of Ezrin, iNOS was detected by immunohistochemistry in 36 well-differentiated MEC cases, 24 poorly-differentiated MEC casese and 60 normal tissues.

Results

The expression of Ezrin and iNOS in normal tissues, welldifferentiated MEC tissues and poorly-differentiated MEC tissues were gradually increased (P <0.05). There was significant positive correlation between Expression of Ezrin and iNOS(P <0.01).Besides, positive correlation was also found between the expression of Ezrin and MEC metastasis(P <0.05) and between iNOS and MEC metastasis (P <0.05).

Conclusions

There is relationship between Ezrin and iNOS, and they were all related to MEC metastasis.
