【摘要】:目的:觀察腦膠質(zhì)瘤組織中突觸融合蛋白8(syntaxin 8,STX8)的表達(dá)情況,并探討其與病理分級(jí)的關(guān)系。方法:收集北京市仁和醫(yī)院2013年5月至2015年12月進(jìn)行手術(shù)治療的腦膠質(zhì)瘤患者57例,將術(shù)后腦膠質(zhì)瘤組織(57例)作為觀察組,其中Ⅰ+Ⅱ級(jí)12例(低級(jí)別)、Ⅲ+Ⅳ級(jí)45例(高級(jí)別),另取正常腦組織(15例)作為對(duì)照組。采用Real-time PCR檢測(cè)STX8 m RNA的表達(dá),免疫組織化學(xué)染色、Western blot方法檢測(cè)STX8的蛋白表達(dá),分析STX8的表達(dá)與腦膠質(zhì)瘤臨床病理的關(guān)系。結(jié)果:與正常腦組織相比,腦膠質(zhì)瘤組織中STX8的m RNA表達(dá)明顯升高,其中在低級(jí)別、高級(jí)別腦膠質(zhì)瘤組織中相對(duì)表達(dá)量分別為:1.685 5±0.071 24、2.820 7±0.069 2,兩組相比,且分別與對(duì)照組(1±0.063 6)相比,差異均有統(tǒng)計(jì)學(xué)意義(P0.05)。免疫組織化學(xué)結(jié)果顯示,腦膠質(zhì)瘤組織中STX8高表達(dá),在正常腦組織中表達(dá)量較低。Western Blot結(jié)果顯示STX8蛋白表達(dá)水平明顯高于正常腦組織(P0.05);其中在低級(jí)別、高級(jí)別腦膠質(zhì)瘤組織中STX8蛋白的相對(duì)表達(dá)量分別為2.271±0.1621、4.937±0.1851,兩組相比,且分別與對(duì)照組相比,差異均有統(tǒng)計(jì)學(xué)意義(P0.05)。統(tǒng)計(jì)學(xué)分析發(fā)現(xiàn)STX8在腦膠質(zhì)瘤組織中的高表達(dá)與患者的性別、年齡及病理分型無(wú)關(guān),但在不同的病理分期之間差異極顯著(P0.01)。結(jié)論:STX8在腦膠質(zhì)瘤組織中異常高表達(dá),可能與腦膠質(zhì)瘤的發(fā)生發(fā)展密切相關(guān)。
