Abstract:

目的研究Cyr61与β-catenin在肝细胞肝癌和肝癌细胞株中的表达及其相关性,探讨二者在肝癌发生中的作用。方法采用免疫组化法检测32例肝细胞肝癌患者肝癌组织中Cyr61与β-catenin蛋白的表达水平;免疫组化法和RT-PCR检测正常肝细胞株L02和肝癌细胞株HepG2、QGY-7701、H22中Cyr61与β-catenin蛋白与mRNA的表达水平;并比较二者的相关性。结果65.63%(21/32)肝癌标本Cyr61蛋白阳性表达,71.88%(23/32)肝癌标本β-catenin蛋白阳性表达,二者合并阳性表达有56.25%(18/32),合并阴性表达有18.75%(6/32),Cyr61表达与β-catenin表达呈正相关(r=0.425,P<0.05);正常肝细胞株L02及肝癌细胞株HepG2、QGY-7701、H22中Cyr61与β-cateninmRNA与蛋白均有表达,二者表达一致性达100%。结论Cyr61与β-catenin在肝癌和肝癌细胞株中高度一致阳性表达,提示Cyr61的表达可能与β-catenin的表达有关,二者可能在肝癌的发生中起到重要作用。
