摘要
目的:探讨ERK1/2和Survivin在食管癌中的表达和二者之间的相关性。方法:应用免疫组化法检测40例食管癌和20例正常食管标本中ERK1/2和Survivin的表达。Westernblot法检测ERK1/2和Survivin在食管癌中的表达以及PD98059对食管癌Eca109细胞株ERK1/2、Survivin表达的影响。免疫共沉淀法检测ERK1/2和Survivin在食管癌Eca109细胞株中的相互作用。结果:ERK1/2和Survivin在食管癌中表达的阳性率分别87.5%和90.0%,在正常食管组织中表达的阳性率为40.0%和5.0%。Westen blot显示ERK1/2和Survivin在食管癌癌组织中的表达高于癌旁组织中的表达。免疫共沉淀结果提示ERK1/2和Survivin在食管癌中的表达存在相互作用。PD98059下调Survivin的表达。结论:ERK1/2和Survivin在食管癌中高表达,在食管癌Eca109细胞中ERK1/2和Survivin表达有相关性,抑制ERK1/2的表达能下调Survivin的表达。在食管癌中Survivin的表达可能依赖于ERK1/2。
