| 摘 要： | 目的探讨Notch1和其配体DLL4蛋白在胃癌组织中的表达及其与肿瘤血管转移之间的关系。方法采用免疫组织化学SP法检测45例胃癌及25例癌旁正常组织中Notch1,DLL4,VEGF的表达情况,并分析它们与各临床病理参数的关系。结果Notch1,DLL4,VEGF蛋白在胃癌中表达的阳性率均明显高于正常胃黏膜组织,差异均有统计学意义(P<0.01)。Notch1蛋白在胃癌中表达与肿瘤浸润深度、淋巴结转移(P<0.01)及远处转移(P<0.05)有关;DLL4蛋白在胃癌中表达与肿瘤浸润深度(P<0.01),淋巴结转移及临床分期(P<0.05)有关;VEGF蛋白在胃癌中表达与浸润深度(P<0.01)、淋巴结转移、远处转移及TNM分期(P<0.05)有关,上述各因素分组间差异有统计学意义。Notch1,DLL4,VEGF蛋白的表达三者两两间均呈正相关关系(rs=0.355,rs=0.367,rs=0.334;均P<0.05)。结论Notch1/DLL4受体通路在胃癌组织中的表达上调与血管内皮生长因子有关,它们可能共同调控肿瘤新生血管形成,参与胃癌的侵袭和转移。

| Abstract: | Objective To investigate the expression of Notch1 and its ligand DLL4 in human gastric carcinoma tissues and its correlation with tumor angiogenic metastasis.Methods Immunohistochemical SP method was used to detect the expression of Notch1,DLL4 and VEGF in 45 gastric carcinoma tissues and paired adjacent normal gastric mucosa,and the relationship between them and clinico-pathological parameters were analyzed.Results The positive expression rate of Notch1,DLL4 and VEGF in gastric carcinoma were higher than t... |
