1、上皮性卵巢癌組織uPA、uPAR及PAI1表達及意義作者:黃翠萍,趙潔,李霞,王蓁單位:青島大學醫(yī)學院附屬醫(yī)院【摘要】目的探討尿激酶型纖溶酶原激活劑(uPA)、uPA受體(uPAR)及其抑制劑(PAI1)在上皮性卵巢癌組織中的表達及意義。方法采用免疫組織化學PV9000法檢測60例上皮性卵巢癌、30例良性卵巢腫瘤及30例正常卵巢組織中uPA、uPAR及PAI1蛋白表達,并結(jié)合臨床病理因素進行分析。結(jié)果uPA、uPAR、PAI1在上皮性卵巢癌中的表達率(75.0%、65.0%、66.7%)明顯高于良性腫瘤(40.0%、33.3%、30.0%)及正常組織
2、(30.0%、26.7%、33.3%),差異均有顯著性(χ2=11.779~19.510,P<0.05),而良性腫瘤與正常組織比較無明顯差異。uPA、uPAR、PAI1在上皮性卵巢癌組織表達與手術(shù)病理分期、組織分級和有無淋巴結(jié)轉(zhuǎn)移有關(guān)(χ2=8.242~36.906,P<0.05)。結(jié)論uPA、uPAR、PAI1在上皮性卵巢癌組織高表達,可能與卵巢癌發(fā)生、發(fā)展及浸潤有關(guān)?!娟P(guān)鍵詞】卵巢腫瘤;尿纖溶酶原激活物;纖溶酶原激活物抑制物1;免疫組織化學 EXPRESSIONSOFuPA,uPARANDPAI1INEPITHELIAL
