1、食管鳞状细胞癌组织中BMP7的表达及其临床意义[摘要]背景与目的:骨形成蛋白7(bonemorphogeneticprotein7,BMP7)是TGF-β家族成员之一,近来研究发现在许多肿瘤中BMP7的表达发生了改变。本研究旨在探讨BMP7在人类食管鳞状细胞癌组织中的表达及其临床意义,研究BMP7与食管鳞癌发生,发展,病理分级,临床分期,浸润程度和淋巴结转移的关系。方法:采用免疫组织化学链霉素抗生物素过氧化酶连接(SP)法和RT-PCR(reversetranscription-polymerasechainreaction)法检测56例新鲜食管鳞癌及对应癌旁
2、正常组织标本中BMP7及BMP7mRNA的表达,结合临床病理资料,研究其与食管鳞癌的相关性。结果:免疫组化显示BMP7在食管鳞癌组织细胞膜和细胞质中有表达,食管鳞癌组织中BMP7的阳性表达率为73.2%(41/56),高于正常食管组织的12.5%(7/56)(χ2=27.225,P<0.001)。RT-PCR显示食管鳞癌组织BMP7mRNA表达明显高于癌旁正常组织(χ2=28.195,P<0.001),食管鳞癌BMP7mRNA的阳性表达与浸润程度,淋巴结转移和TNM分期有关(P<0.05),而与性别,年龄和组织学分级无关。结论:BMP7可能在食管鳞癌的发生、发
