(CEACAM6 ) Carcinoembryonic 抗原相关的房间粘附分子 6 证明在许多 humancancers 的增加的表示，和它的在表示上与提高的移植被联系，侵略，并且在 vivo 转移。这里，我们报导 CEACAM6 在房间衬里的胃的癌症(GC ) 和肿瘤纸巾是起来调整的。在 MKN-45 和 SGC-7901 GC 房间的 Over-expressionof CEACAM6 在 athymic 老鼠在 vitro 和转移支持了移植和侵略，而 MKN-28 和 SNU-16 GC 房间的移植和侵略被 knockdownof CEACAM6 压制。当 CEACAM6 是 over-expressedin SGC-7901 房间时，我们也观察到类固醇受体激活剂(C-SRC ) phosphorylation 被增加。一起拿，这些结果建议 CEACAM6 在 GC 作为 oncoprotein 工作并且可以是 importantmetastatic biomarker 和治疗学的目标。

英文摘要：

Carcinoembryonic antigen-related cell adhesion molecule 6 （CEACAM6） shows increased expression in a wide variety of human cancers, and its over-expression is associated with enhanced migration, invasion, and in vivo metastasis. Here, we reported that CEACAM6 was up-regulated in gastric cancer （GC） cell lines and tumor tissues. Overexpression of CEACAM6 in MKN-45 and SGC-7901 GC cells promoted migration and invasion in vitro and metastasis in athymic mice, whereas migration and invasion of MKN-28 and SNU-16 GC cells were suppressed by knockdown of CEACAM6. We also observed that steroid receptor coactivator （C-SRC） phosphorylation was increased when CEACAM6 was over-expressed in SGC-7901 cells. Taken together, these results suggested that CEACAM6 functions as an oncoprotein in GC and may be an important metastatic biomarker and therapeutic target.
