      摘 要 目的:探討細(xì)胞視黃酸結(jié)合蛋白(cellular retinoic acid-binding protein Ⅱ,CRABPⅡ)和表皮脂肪酸結(jié)合蛋白(epidermal fatty acid-binding protein,E-FABP)的差異表達(dá)在乳腺癌中的意義,以及與臨床病理特征和分型的關(guān)系。方法:分析123例浸潤性乳腺癌患者的臨床資料,采用免疫組化法檢測乳腺癌組織中CRABPⅡ和E-FABP的表達(dá)。結(jié)果:CRABPⅡ和E-FABP在浸潤性乳腺癌的表達(dá)存在顯著差異(P<0.01)。此差異表達(dá)分為E-FABP≥CRABPⅡ與E-FABP﹤CRABPⅡ兩種。在浸潤性乳腺癌中,E-FABP≥CRABPⅡ的表達(dá)較多見。CRABPⅡ和E-FABP的差異表達(dá)與腋窩淋巴結(jié)轉(zhuǎn)移和TNM分期有關(guān)(P<0.05)。差異表達(dá)與病理分型相關(guān),Luminal A型中E-FABP≥CRABPⅡ的百分率最低(61.6%),Basal-like型中的百分率最高(95.2%)。結(jié)論:在浸潤性乳腺癌中,CRABPⅡ和E-FABP的差異表達(dá)可能與乳腺癌的侵襲性及預(yù)后相關(guān),E-FABP≥CRABPⅡ時的乳腺癌侵襲性高、預(yù)后差。

      ABSTRACT Objective: To explore the significance of the different expressions of cellular retinoic acid-binding protein Ⅱ (CRABPⅡ) and epidermal fatty acid-binding protein (E-FABP) in the breast cancer and the relationship of their clinical pathological features and types. Methods: The clinical data on 123 cases with invasive breast cancer were analyzed and the expressions of CRABPⅡ and E-FABP were detected by immunohistochemistry in the breast cancer tissues. Results: There existed different expressions between CRABⅡ and E–FABP in the invasive breast cancer (P<0.01), which could be classified into two types of E-FABP≥CRABPⅡ and E-FABP

      據(jù)統(tǒng)計,我國每年乳腺癌發(fā)病16.9萬,是女性最常見的惡性腫瘤[1]。近年來的研究顯示,細(xì)胞視黃酸結(jié)合蛋白(cellular retinoic acid-binding protein Ⅱ,CRABPⅡ)和表皮脂肪酸結(jié)合蛋白(epidermal fatty acid-binding protein,E-FABP)作為維甲酸的轉(zhuǎn)運(yùn)蛋白,參與維甲酸調(diào)節(jié)細(xì)胞分化,調(diào)控細(xì)胞周期,誘導(dǎo)細(xì)胞凋亡。

      CRABPⅡ參與抑制細(xì)胞生長,而E-FABP參與促進(jìn)細(xì)胞增殖。兩者在維甲酸信號通路上發(fā)揮不同的作用,從相反兩方面影響細(xì)胞的增殖和凋亡[2]。E-FABP 在乳腺浸潤性導(dǎo)管癌組織呈高表達(dá),提示其與腫瘤的發(fā)生和發(fā)展密切相關(guān)[3],可作為乳腺癌的獨立預(yù)后指標(biāo)[4]。CRABPⅡ能抑制腫瘤細(xì)胞的增殖和侵襲,在腫瘤組織中部分表達(dá)缺失,說明其減弱或缺失與腫瘤的發(fā)生可能有關(guān)[2]。兩者的差異表達(dá)與乳腺癌的發(fā)生發(fā)展及預(yù)后可能相關(guān)。為進(jìn)一步明確CRABPⅡ和E-FABP的差異表達(dá)在乳腺癌中的意義,本研究采用免疫組化法檢測CRABPⅡ和E-FABP在浸潤性乳腺癌中的表達(dá),探討兩者的差異表達(dá)與臨床病理特征和乳腺癌病理分型的關(guān)系。

      材料與方法

      資料

      從2012年1月至5月黃浦區(qū)中心醫(yī)院收治女性乳腺癌患者中收集具有完整臨床資料的123例為研究對象,年齡32~85歲,中位年齡 54歲。患者的臨床病理資料完整,包括腫塊大小、腋窩淋巴結(jié)轉(zhuǎn)移數(shù)目、組織類型,以及雌激素受體(estrogen receptor, ER)、孕激素受體(progesterone receptor, PR)、人表皮生長因子受體-2(human epidermal growth receptor-2, HER-2)、ki-67和熒光原位雜交(FISH)檢測結(jié)果。根據(jù)2012年WHO乳腺腫瘤組織學(xué)分類標(biāo)準(zhǔn)[5],123例中非特殊型浸潤性癌99例,特殊亞型24例,包括浸潤性篩狀癌、浸潤性小葉癌、黏液癌、伴神經(jīng)內(nèi)分泌癌特征的乳腺癌、化生性癌。根據(jù)2009年UICC/AJCC乳腺癌病理 TNM分期標(biāo)準(zhǔn),I期50例,Ⅱ期53例,Ⅲ期20例。所有患者均接受乳腺癌改良根治術(shù)或根治術(shù),術(shù)前未行放、化療和免疫治療。討論

      本研究中,在浸潤性乳腺癌中表達(dá)率各不同,兩者的表達(dá)存在差異。浸潤性乳腺癌中表達(dá)較多見,即E-FABP在浸潤性乳腺癌的陽性分布較CRABPⅡ占優(yōu)勢,可能與兩者在維甲酸調(diào)節(jié)細(xì)胞作用不同有關(guān)。Schug等[11]的研究認(rèn)為這兩種結(jié)合蛋白的差異表達(dá),會引起維甲酸產(chǎn)生不同的效應(yīng)。CRABPⅡ/E-FABP呈高比例時,主要通過維甲酸受體通路,發(fā)揮促凋亡作用;相反,當(dāng)CRABPⅡ/E-FABP呈低比例時,則主要通過過氧化物酶體增殖物激活受體通路,發(fā)揮促增殖的作用。維甲酸受體和過氧化物酶體增殖物激活受體可以存在于同一種細(xì)胞或同一細(xì)胞中,細(xì)胞中CRABPⅡ和E-FABP的比例關(guān)系決定維甲酸激活何種核受體,從而影響細(xì)胞的增殖和凋亡。
