摘要 目的:探讨肝素酶表达在胃癌发生、发展中的作用。方法:用逆转录聚合酶链反应(RT-PCR)和实时荧光定量聚合酶链反应(FQ-PCR)测定42例胃癌和26例非癌组织中肝素酶的表达情况。采用χ2检验比较肝素酶的表达与胃癌临床病理特征之间的关系。结果:胃癌中肝素酶呈阳性表达26例(61.9%);非癌组织中呈弱阳性表达1例(3.8%)。RT-PCR和FQ-PCR的检测结果均相同。胃癌TNM分期中Ⅲ、Ⅳ期肝素酶mRNA表达阳性率明显高于Ⅰ、Ⅱ期(P<0.05);肝素酶表达与浆膜浸润、淋巴结转移或远端转移呈相关性(P<0.05)。结论:肝素酶可能促进胃癌浸润和转移,在胃癌的转移途径中,参与淋巴道转移而非血道转移。肝素酶可作为预测胃癌复发、转移的分子标志物之一。
