【摘要】：背和目的:高爾基體磷蛋白3(Golgi phosphoprotein3, GOLPH3)是于2009年6月才發(fā)現(xiàn)的癌基因，研究表明這種基因能促進腫瘤細胞的生長、分化和增殖，機制可能是調(diào)節(jié)哺乳動物雷帕霉素靶蛋白（mammalian target of rapamycin,mTOR)信號通路，腫瘤細胞對雷帕霉素的敏感性也受此基因調(diào)節(jié)�，F(xiàn)有的研究提示Golph3在神經(jīng)膠質(zhì)瘤，前列腺癌,乳腺癌等均有明顯的表達，目前國內(nèi)外關(guān)于GOLPH3在腫瘤中表達的研究還比較少。本研究通過檢測GOLPH3在上皮性卵巢癌及正常卵巢組織中的表達，，探討GOLPH3,與上皮性卵巢癌臨床病理指標(biāo)的關(guān)系以及其是否能成為卵巢癌分子靶向治療又一新靶點。 方法：回顧分析31例上皮性卵巢癌患者及31例子宮良性腫瘤行卵巢切除患者的臨床及病理資料。采用免疫組化的方法(SP法)檢測31例上皮性卵巢癌組織、31例正常卵巢組織中GOLPH3的表達;采用卡方檢驗及秩和檢驗等方法分GOLPH3表達與上皮性卵巢癌臨床病理因素的關(guān)系。 結(jié)果：1,GOLPH3免疫染色定位于細胞質(zhì)中主要有兩個模式，一是凝聚成較大的顆粒分布在細胞核周圍，二是以細顆粒的形式分散在細胞質(zhì)中,GOLPH3在上皮性卵巢癌中的表達與在正常卵巢組織中表達相比有顯著增高，差異具有統(tǒng)計學(xué)意義(x2=47.032P0.05)。 2，GOLPH3在上皮性卵巢癌不同分期、不同分級分組間的陽性表達強度差異也同樣具有統(tǒng)計學(xué)意義(P0.05)，且其陽性表達隨分期、分級的增高而增強(P0.05),但在年齡、病理組織類型分組中的表達差異沒有統(tǒng)計學(xué)意義(p0.05)。 結(jié)論:1, GOLPH3在上皮性卵巢癌中的陽性表達率明顯高于正常卵巢組織，提示上皮性卵巢癌的發(fā)生與GOLPH3的異常表達之間存在密切相關(guān)性。 2,隨著腫瘤的分期、分級的增高，GOLPH3在上皮性卵巢癌中的陽性表達也增強，從而提示GOLPH3表達強度與上皮性卵巢癌惡性程度及腫瘤進展程度成正向相關(guān)，GOLPH3也許能成為輔助判斷上皮性卵巢癌預(yù)后好壞的標(biāo)志物,需要進一步研究。 3, GOLPH3在上皮性卵巢癌組織中高表達現(xiàn)象，提示GOLPH3很可能成為卵巢癌靶向治療的一個有利靶點
[Abstract]:Back and objective: Golgi phosphoprotein 3 (GOLPH3) is a oncogene discovered in June 2009, which has been shown to promote the growth, differentiation and proliferation of tumor cells. The mechanism may be the regulation of mammalian rapamycin target protein mammalian target of rapamycin mTOR. the sensitivity of tumor cells to rapamycin is also regulated by this gene. The existing studies suggest that Golph3 is expressed in gliomas, prostate cancer, breast cancer and so on. At present, there are few studies on the expression of GOLPH3 in tumors at home and abroad. In this study, we examined the expression of GOLPH3 in epithelial ovarian carcinoma and normal ovarian tissues, and explored the relationship between GOLPH3 and clinicopathological parameters of epithelial ovarian cancer and whether it could be a new target for molecular targeted therapy of ovarian cancer. Methods: the clinical and pathological data of 31 patients with epithelial ovarian cancer and 31 patients with benign uterine tumor were retrospectively analyzed. Immunohistochemical method was used to detect the expression of GOLPH3 in 31 normal ovarian tissues from 31 cases of epithelial ovarian carcinoma and the relationship between GOLPH3 expression and clinicopathological factors of epithelial ovarian carcinoma was analyzed by chi-square test and rank sum test. Results there were two main patterns in the cytoplasm of the cytoplasm, one was the aggregation of larger particles around the nucleus, and the other was the distribution of large particles around the nucleus. The expression of GOLPH3 in epithelial ovarian carcinoma was significantly higher than that in normal ovarian tissue, and the difference was statistically significant. 2the positive expression intensity of GOLPH3 in different stages of epithelial ovarian cancer was also significantly different among different grading groups, and the positive expression of GOLPH3 increased with the stage and grade, but at the age, the positive expression of GOLPH3 was increased with the stage and grade of ovarian carcinoma, but at the age, the positive expression of GOLPH3 was increased with the stage and grade of epithelial ovarian cancer. There was no significant difference in the expression of P0. 05 in the histopathologic groups. Conclusion the positive expression rate of GOLPH3 in epithelial ovarian carcinoma is significantly higher than that in normal ovarian tissue, suggesting that there is a close correlation between the occurrence of epithelial ovarian cancer and abnormal expression of GOLPH3. 2. With the stage of the tumor, the positive expression of GOLPH3 in epithelial ovarian cancer was also increased with the increase of grade. The results suggest that the positive correlation between the expression of GOLPH3 and the malignant degree and progression of epithelial ovarian cancer may be a marker of the prognosis of epithelial ovarian cancer, which needs further study. 3. The overexpression of GOLPH3 in epithelial ovarian cancer tissues suggests that GOLPH3 may be a favorable target for the targeted therapy of ovarian cancer.
