卵巢黏液性肿瘤中claudin-3、claudin-4的表达及其意义

目的 探讨claudin-3、-4在卵巢黏液性囊腺癌的发生、发展过程中的作用.方法 应用免疫组织化学、原位杂交方法检测卵巢上皮、黏液性囊腺瘤、交界性黏液性囊腺瘤、黏液性囊腺癌的石蜡包埋组织中claudin-3、-4和claudin-4 mRNA的表达情况.结果 claudin-3、-4、claudin-4 mRNA在卵巢上皮及卵巢黏液性囊腺瘤中表达最弱;交界性黏液囊腺瘤中表达明显增强,却明显弱于黏液性囊腺癌(P<0.05);在低分化卵巢癌中的表达强于高分化癌及中分化癌(P<0.05),中分化癌与高分化癌中的表达无统计学意义(P>0.05).结论 claudin-3、-4表达增强,与黏液性囊腺癌的发生、发展密切相关,与其分化程度有关,可能会成为诊断卵巢黏液性囊腺癌的特异性标记物.

The expression of daudin3 and clandin4 in ovarian mucous cystadenoma and it's significance

Objective To explore the role of claudin-3, claudin-4 in carcinogenesis and progression of ovarian mucous cystoadenocarcinoma. Methods Immunohistochemical and in situ hybridization method were employed to detect the expression of claudin-3, -4, claudin-4 mRNA in ovary epithelium, mucinous cystadeno-nut, mucinous cystadenoma of borderline, mucous cystadenocarcinoma. Results claudin-3, -4 expression was lowest in ovarian epithelium and mucinous cystadenoma, higher in borderline mucinous cystadenoma, and high-est in ovarian cystadenocarcinoma(P<0.05 ). The expression of claudin-3, -4 in poor differentiated ovarian carcinoma was stronger than that in well- differentiated and moderately differentiated carcinoma (P< 0.05 ),but there was no significant difference between well-differentiated and moderately differentiated carcinoma(P>0.05). Conclusion The overexpvession of claudin-3, -4 is correlated closely with the carcinogenesis and advancement of ovarian mucinous carcinoma, and may have correlation with the differentiated degree of o-varian carcinoma, claudin-3, -4 may become the specific markers of ovarian mucous cystadenocarcinoma.
