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