【摘要】: 目的 檢測(cè)WWOX、p53及Bcl-2 mRNA及其蛋白在鼻咽癌中的表達(dá)并分析其臨床意義。方法 收集2009年6月至2009年10月間在我院耳鼻喉科初診、有完整臨床及病理資料的鼻咽癌患者鼻咽部組織61例,鼻咽粘膜慢性炎組織20例,用RT-PCR方法檢測(cè)WWOX. p53及Bcl-2 mRNA表達(dá)情況,應(yīng)用免疫組化方法檢測(cè)相應(yīng)組織的蛋白表達(dá)情況,并探討WWOX、p53和Bcl-2的表達(dá)及意義。 結(jié)果 1. WWOX的表達(dá)情況 WWOX mRNA在鼻咽癌和鼻咽粘膜慢性炎組織中平均表達(dá)水平分別為0.69±0.34和0.89±0.49,WWOX蛋白在鼻咽癌和鼻咽粘膜慢性炎組織中陽(yáng)性表達(dá)率分別為39.34%和70.00%,WWOX mRNA和蛋白在鼻咽癌組織中的表達(dá)低于鼻咽粘膜慢性炎組織,p0.05;WWOX蛋白在鼻咽癌Ⅲ-Ⅳ期的表達(dá)低于Ⅰ~Ⅱ期,p0.05;在有淋巴結(jié)轉(zhuǎn)移的病例中WWOX蛋白的表達(dá)低于無(wú)淋巴結(jié)轉(zhuǎn)移者,p0.05。分別對(duì)WWOX蛋白的陽(yáng)性表達(dá)在鼻咽癌患者不同性別、不同年齡段和各病理分型中進(jìn)行比較,差異無(wú)統(tǒng)計(jì)學(xué)意義,p0.05。 2.p53的表達(dá)情況 p53 mRNA在鼻咽癌和鼻咽粘膜慢性炎組織中平均表達(dá)水平分別是0.88±0.59和0.51±0.21,p53蛋白在鼻咽癌和鼻咽粘膜慢性炎組織中陽(yáng)性表達(dá)率分別為80.33%和40.00%, p53 mRNA和蛋白在鼻咽癌組織中的表達(dá)高于鼻咽粘膜慢性炎組織,p0.05;p53蛋白在鼻咽癌Ⅲ-Ⅳ期的陽(yáng)性表達(dá)明顯高于鼻咽癌Ⅰ~Ⅱ期,p0.05;p53蛋白的陽(yáng)性表達(dá)在有無(wú)淋巴結(jié)轉(zhuǎn)移間的比較,差異無(wú)統(tǒng)計(jì)學(xué)意義,p0.05,分別對(duì)不同性別、不同年齡段和各病理分型中的陽(yáng)性表達(dá)進(jìn)行比較,差異無(wú)統(tǒng)計(jì)學(xué)意義,p0.05。 3.Bcl-2的表達(dá)情況 Bcl-2 mRNA在鼻咽癌和鼻咽粘膜慢性炎組織中表達(dá)水平分別是0.44±0.32和0.24±0.11,Bcl-2蛋白在鼻咽癌和鼻咽粘膜慢性炎組織中陽(yáng)性表達(dá)率分別為85.25%和35.00%,Bcl-2 mRNA和蛋白在鼻咽癌組織中的表達(dá)高于鼻咽粘膜慢性炎組織,p0.05;Bcl-2蛋白的陽(yáng)性表達(dá)在鼻咽癌ⅠⅡ期和Ⅲ~Ⅳ期間的比較,差異無(wú)統(tǒng)計(jì)學(xué)意義,分別對(duì)不同性別、不同年齡段、有無(wú)淋巴結(jié)轉(zhuǎn)移及各病理分型中的陽(yáng)性表達(dá)進(jìn)行比較,差異無(wú)統(tǒng)計(jì)學(xué)意義,p0.05。 4. WWOX與p53及Bcl-2蛋白在鼻咽癌組織中表達(dá)的相關(guān)性 在鼻咽癌組織中,WWOX與p53表達(dá)呈負(fù)相關(guān),差異具有統(tǒng)計(jì)學(xué)意義,p0.05。 在鼻咽癌組織中,WWOX與Bcl-2表達(dá)呈負(fù)相關(guān),差異具有統(tǒng)計(jì)學(xué)意義,p0.05。 結(jié)論 1. WWOX mRNA及蛋白在鼻咽癌組織中呈低表達(dá),與鼻咽癌的TNM分期、有無(wú)淋巴結(jié)轉(zhuǎn)移有關(guān),提示W(wǎng)WOX的異常表達(dá)可能參與鼻咽癌的發(fā)生、發(fā)展,且與其預(yù)后有關(guān)。 2. p53 mRNA及蛋白在鼻咽癌組織中呈高表達(dá),與鼻咽癌的TNM分期有關(guān),提示p53的異常表達(dá)可能參與鼻咽癌的發(fā)生、發(fā)展。 3. Bcl-2 mRNA及蛋白在鼻咽癌組織中呈高表達(dá),與鼻咽癌的TNM分期、有無(wú)淋巴結(jié)轉(zhuǎn)移、病理分型、性別和年齡無(wú)關(guān),提示Bcl-2的異常是鼻咽癌變的較早期事件,與鼻咽癌的淋巴轉(zhuǎn)移和預(yù)后關(guān)系可能不大。 4. WWOX與p53和Bcl-2在鼻咽癌組織中的表達(dá)呈負(fù)相關(guān),提示W(wǎng)WOX與p53和Bcl-2在鼻咽癌的發(fā)生、發(fā)展中可能相互影響,共同或協(xié)同起作用。
