贲门腺癌(GCA)是胃癌中最具侵袭性的亚型,转移率高。在这份报告中,我们收集了214例GCA病例的肿瘤组织样本,并使用组织微阵列分析(TMA)通过免疫组织化学(IHC)染色检测了GCA肿瘤中Hippo-YAP/TAZ通路的靶基因产物CYR 61的表达。结果表明,CYR 61在44%的GCA肿瘤样品中过表达。CYR 61的表达与GCA患者的累积存活率呈负相关(p<0.001),并且仅与转移性病理分类显著相关(N分类,p=0.052; TNM分期,p=0.001)。此外,胃癌AGS细胞中CYR 61的敲低损害癌细胞的迁移和侵袭,表明CYR 61在转移中的驱动作用。因此,我们的研究建立了CYR 61作为转移生物标志物的预测GCA的预后不良,并提供了一个潜在的分子靶点,抗转移治疗GCA。
Gastric cardia adenocarcinoma (GCA) is the most aggressive subtype of gastric cancer with a high metastatic rate. In this report, we collected tumor tissue samples from 214 GCA cases and examined expression of CYR61, a target gene product of the Hippo-YAP/TAZ pathway, in the GCA tumors by immunohistochemical (IHC) staining using the tissue microarray assay (TMA). The results have shown that CYR61 is overexpressed in 44% of the GCA tumor samples. Expression of CYR61 is inversely correlated with cumulative survival of GCA patients (p<0.001) and significantly associated only with metastatic pathological categories (with N category, p=0.052; with TNM stage, p=0.001). Furthermore, knockdown of CYR61 in gastric cancer AGS cells impairs the cancer cell migration and invasion, suggesting a driver role of CYR61 in metastasis. Thus, our studies have established CYR61 as a metastatic biomarker for prediction of poor prognosis of GCA and provided a potential molecular target for anti-metastatic therapy of GCA.
