卵巢癌组织中的表达状况及临床意义


【摘要】
目的:探讨人组织激肽释放酶11基因(KLKll基因)在卵巢癌组织中的表达状况。方
法:应用免疫组织化学及逆转录PCR方法检测KLKll基因在卵巢癌组织、卵巢良性肿瘤组织及 正常卵巢组织中的表达状况,研究其与肿瘤分期、组织病理学分型等相关预后因素的关系。结
果:KLKll mRNA及其蛋白hKll均在卵巢上皮细胞中表达,在卵巢癌组织中的表达均低于其在

正常卵巢组织和卵巢良性肿瘤组织的表达;hKll蛋白在浆液性卵巢癌组织的表达高于其他类型 的卵巢癌组织(P=0.012);早期卵巢癌(I/Ⅱ期)组织中hKll蛋白的表达明显高于晚期卵巢 癌(Ⅲ/Ⅳ期)(P=0.010);hKl l蛋白在卵巢癌组织的表达水平与肿瘤的病理分级无明显关系 (P=O.747);高水平的KLKll基因表达与卵巢癌临床分期等预后因素有明显相关性。结论:在 卵巢癌组织中存在KLKIl基因的表达下调,提示KLKll基因在卵巢癌中表达失调,可能对卵巢 癌的诊断有一定价值。
