Syndecan-1和HPA-1 mRNA在胃癌组织中的表达及其与胃癌侵袭转移的关系

背景与目的：Syndecan-1和HPA-1（乙酰肝素酶-1）可能参与多种恶性肿瘤的侵袭转移,但关于两者与胃癌的关系较少报道。本研究旨在探讨Syndecan-1mRNA和HPA-1mRNA在胃癌组织中的表达及两者与胃癌侵袭转移的关系。方法：采用实时荧光定量逆转录聚合酶链反应（RT-PCR）分别检测了58例胃癌及58例配对的癌旁组织（距癌2cm）和58例配对远离胃癌的手术切缘正常组织（距癌5cm以上）Syndecan-1和HPA-1的mRNA的表达水平,分析探讨两者与胃癌临床病理特征和胃癌侵袭转移的关系。结果：HPA-1mRNA在胃癌中表达的阳性率（86.2%）显著高于癌旁组织（27.6%）和正常组织（5.2%）（P均〈0.001）,癌旁组织明显高于正常组织（P均〈0.05）。Syndecan-1mRNA在正常组织中表达的阳性率（98.3%）显著高于癌旁组织（25.9%）和胃癌组（5.2%）（P均〈0.001）,癌旁组织中明显高于胃癌组织（P均〈0.05）。Syndecan-1的表达减弱和HPA-1的表达增强与肿瘤的分化程度、浸润深度、淋巴结转移、远处转移及TNM分期显著相关（P〈0.05）。Syndecan-1mRNA的表达与HPA-1mRNA的表达呈负相关。结论：Syndecan-1mRNA在正常胃组织中呈高表达,HPA-1mRNA在胃癌组织中呈高表达,且Syndecan-1的表达减弱与HPA-1的表达增强可促进胃癌的侵袭转移。联合检测Syndecan-1mRNA及HPA-1mRNA对于指导胃癌临床治疗及判断预后有重要价值。

Expression of Syndecan-1 and HPA-1 and their relationship with the invasion and metastasis of gastric carcinoma

Background and purpose:Syndecan-1 and HPA-1 may be involved in the progression of invasion and metastasis of many malignant tumors, but there are few reports about the relationship between the two gene expressions in gastric carcinomas. This study was aimed to explore the expression of Syndecan-1 and HPA-1 mRNA in gastric carcinoma and their relationship with the invasion and metastasis of gastric carcinoma. Methods: Real-time polymerase chain reation (RT-PCR) was used to detect mRNA of Syndecan-1 and HPA-1...
