摘要: 目的: 探讨Livin和张力蛋白同源10q丢失的磷酸酶基因(phosphatase and tensin hornology deleted on chromosome 10,PTEN)的表达与卵巢上皮性癌的临床病理学特征的关系及其相关性。方法: 采用免疫组织化学EliVision法检测60例卵巢上皮性癌组织、20例良性卵巢上皮性肿瘤及20例正常卵巢组织中Livin及PTEN表达情况。结果: 卵巢上皮性癌中Livin阳性率(80.0%)均明显高于卵巢良性上皮性肿瘤(10.0%)及正常卵巢组织(5.0%)(P<0.01)。卵巢上皮性癌的组织病理学分级间Livin的阳性率差异有统计学意义(P<0.01),而在临床分期及淋巴结转移中差异均无统计学意义(P>0.05)。卵巢上皮性癌中PTEN的阳性率(26.7%)均明显低于卵巢良性上皮性肿瘤(95.0%)及正常卵巢组织(100.0%)(P<0.01);卵巢上皮性癌的临床分期、组织病理学分级及淋巴结有无转移间PTEN的阳性率差异均有统计学意义(P<0.01)。卵巢上皮性癌中Livin的阳性率与PTEN的阳性率呈负相关关系(P<0.01)。结论: Livin的表达上调及PTEN的表达下调在卵巢上皮性癌的发生、分化进展中起重要作用,Livin基因有可能成为治疗卵巢癌的新靶点。

Abstract: Objective: To study the expression and pathological characteristics of Livin and PTEN proteins in epithelial ovarian carcinoma as well as their inter-relationship. Methods: The Expression of Livin and PTEN in 60 samples of ovarian epithelial carcinoma,20 samples of benign ovarian epithelial tumor and 20 normal ovarian tissues were detected by immunohistochemistry. Results: The Livin protein expression (80.0%) in epithelial ovarian carcinoma tissues was significantly higher than that of benign ovarian epithelial tumors (10.0%) and normal ovarian tissues (5.0%) (P<0.01). The expression of Livin had a positive correlation with the tumor grade,but no statistical correlation with the tumor stage or lymph node metastasis. The positive expression of PTEN protein in epithelial ovarian carcinoma (26.7%) was significantly lower than that in benign ovarian epithelial tumors (95.0%) and normal ovarian tissues (100.0) (P<0.01). The expression of PTEN was negatively related to the tumor stage,tumor grade and lymph node metastasis (P<0.01); the expression of Livin was negatively correlated with the expression of PTEN (P<0.01). Conclusions: Up-regulated expression of Livin and down-regulated expression of PTEN may play an important role in the process of carcinogenesis and differentiation of epithelial ovarian carcinoma. Livin may be useful targets for treatment of ovarian carcinoma.
