摘要: [摘要]〓
〖HTH〗目的〖HTSS〗〖KG*2〗观察野生型p53诱导的蛋白磷酸酶1(Wildtype p53induced phosphatase 1,Wip1)在卵巢浆液性囊腺癌组织中的表达并探讨Wip1与卵巢浆液性囊腺癌临床病理特征的关系。
〖HTH〗方法〖HTSS〗〖KG*2〗 采用免疫组织化学、实时荧光定量反转录-聚合酶链反应(realtime fluorescent quantitative reverse transcriptionpolymerase chain reaction,RTPCR)及Western blot方法检测卵巢浆液性囊腺癌50例、交界性卵巢浆液性囊腺瘤20例、正常卵巢组织10例中Wip1表达阳性率、Wip1 mRNA和Wip1蛋白的表达水平。
〖HTH〗结果〖HTSS〗〖KG*2〗卵巢浆液性囊腺癌组织和交界性卵巢浆液性囊腺瘤中Wip1的表达阳性率明显高于正常卵巢组织,差异有统计学意义(P<005);卵巢浆液性囊腺癌与交界性卵巢浆液性囊腺瘤组织中Wip1表达阳性率差异无统计学意义(P>005);卵巢浆液性囊腺癌组和交界性卵巢浆液性囊腺瘤组中Wip1 mRNA的表达明显高于正常卵巢组织,差异有统计学意义(P<005);卵巢浆液性囊腺癌组和交界性卵巢浆液性囊腺瘤组中Wip1蛋白的表达明显高于正常卵巢组织,差异有统计学意义(P<005);卵巢浆液性囊腺癌组中病理分期Ⅲ+Ⅳ期患者较Ⅰ+Ⅱ期患者Wip1表达阳性率高,差异有统计学意义(P<005);有淋巴结转移者较无淋巴结转移者Wip1表达阳性率高,差异有统计学意义(P<005);不同组织分级患者Wip1表达阳性率差异无统计学意义(P>005)。
〖HTH〗结论〖HTSS〗〖KG*2〗Wip1在卵巢浆液性囊腺癌组织中高表达,与淋巴结转移、临床分期、组织学分级密切相关。Wip1参与了卵巢浆液性囊腺癌的发生发展过程。

Abstract: [Abstract] Objective〖HTSS〗〓To explore expression of wildtype p53induced phosphatase 1(Wip1) in ovarian serous cystadenocarcinoma tissues and its relationship with clinicopathological features.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓The positive expression of Wip1 as well as the expression of Wip1 mRNA and  Wip1 protein in ovarian serous cystadenocarcinoma tissues(n=50),ovarian serous cystadenoma tissues(n=20) and normal ovarian tissues(n=10) were detected by immunohistochemistry, realtime fluorescent quantitative reverse transcriptionpolymerase chain reaction(RTPCR) and Westernblot.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓 The expression of Wip1 was significantly higher in ovarian serous cystadenocarcinoma and borderline ovarian serous cystadenoma tissues than in normal ovarian tissues (P<005). There was no significant difference in positive expression of Wip1  between ovarian serous cystadenocarcinoma tissues and  borderline ovarian serous cystadenoma tissues(P>0.05). Wip1 mRNA expression in borderline ovarian serous cystadenoma  and ovarian serous cystadenocarcinoma tissues were highly increased, as compared with normal ovarian tissues,and the difference was significant (P<005). The expressions of Wip1 protein were remarkably higher in ovarian serous cystadenocarcinoma and ovarian serous cystadenocarcinoma tissues than in normal ovarian tissues, and the difference was statistically significant (P<005). The  positive expression of Wip1 in stage Ⅲ and Ⅳ of ovarian serous cystadenocarcinoma tissues was significantly higher than that in stageⅠandⅡ(P<005). The positive expression of Wip1 was notably higher in groups with lymph node metastasis, as compared with groups without lymph node metastasis(P<005). There was no significant difference in the positive expression of Wip1 in carcinomas of different histological grades(P>005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓Wip1 is highly expressed in ovarian serous cystadenocarcinoma,which is closely associated with lymph node metastasis, clinical staging and histological grade. It is suggested that Wip1 is involved in the development and progression of ovarian serous cystadenocarcinoma.
