  • 简介:瞄准:在食道的有鳞的房间癌(ESCC)调查midkine的表示并且与clinicopathological特征分析它的关系。方法:RT-PCR和免疫细胞化学的染色被用来分别地在EC109房间检测midkinemRNA和蛋白质的表示。然后,在ESCC样品的66种情况中的midkine的表示被免疫组织化学对人的midkine用单音的同种细胞的抗体检测。结果:Midkine被RT-PCR和免疫细胞化学在EC109房间表示。免疫反应在56.1%被检测(37/66)ESCC样品。midkine的表示在肿瘤房间的细胞质被发现。尤其是,midkine的紧张在充满容器和肿瘤的入侵的边阶的区域是更强壮的。Midkine更强烈地比在中等并且糟糕区分的肿瘤在很好区分的肿瘤(76.9%)被表示(43.1%和41.2%,分别地)(P<0.05)。在midkine之间没有统计上重要的关联在ESCC的表示和性,年龄,临床的阶段,淋巴节点转移或幸存。结论:Midkine完了在ESCC表示了。它可以在肿瘤血管生成和侵略起一个作用。midkine的表示在ESCC与肿瘤细胞分化被相关。肿瘤房间区分越多糟糕,midkine表示越多weaker。
