摘要
目的探讨Notch1及Jagged1蛋白在肝脏肿瘤中的表达特点及其与肝癌的临床病理学特点的关系。方法采用免疫组织化学SP法检测65例肝癌组织及其相应癌旁正常组织中Notch1和Jagged1蛋白的表达。结果在肝癌和癌旁正常组织中,Notch1的阳性表达率分别为16.9%和90.8%;Jagged1的阳性表达率分别为10.9%和86.2%,两组间差异均有显著性(P=0.000)。Notch1受体和Jagged1配体分子的表达与患者年龄、性别,肿瘤大小无关;Notch1受体表达与肝癌组织学分型、Edmondson分级及有无淋巴结转移无关(P>0.05);而Jagged1配体表达则与肝癌组织学分型、Edmondson分级及有无淋巴结转移有关(P<0.05);在肝癌组织中Notch1与Jagged1的表达呈正相关(rs=0.301,P=0.005)。结论 Notch1蛋白和Jagged1蛋白可以作为诊断肝癌的特异性指标,也有望成为肝癌基因治疗的新靶点。
