摘要

目的

探讨HPSE2在胃癌组织中的表达及其对胃癌生存预后及胃癌细胞侵袭迁移的影响。

方法

将胃腺癌组织芯片进行HPSE2的免疫组化染色，检测其在癌及癌旁组织中的表达，分析其表达水平与胃癌临床特征、生存预后及预后影响因素的关系。构建HPSE2过表达载体，转染胃癌细胞建立HPSE2过表达细胞，Transwell实验检测HPSE2过表达对胃腺癌细胞迁移和侵袭的影响。

结果

HPSE2在胃腺癌组织的平均病理评分为4.56，癌旁组织为7.18，HPSE2在胃腺癌组织中的表达显著低于癌旁组织(

0.05)。HPSE2的表达水平与肿瘤大小、淋巴结转移及临床分期相关，并且HPSE2蛋白高表达患者的中位生存时间和累积生存率均显著高于低表达患者(

0.05)。Cox比例风险模型结果显示，临床分期、肿瘤大小和HPSE2蛋白表达是影响胃腺癌患者预后的风险因素(

0.05)。胃癌细胞过表达HPSE2可明显抑制胃癌细胞的侵袭和迁移。

结论

HPSE2蛋白在胃腺癌组织低表达，与肿瘤大小、临床分期及患者的生存预后相关，HPSE2过表达可明显抑制胃癌细胞的侵袭迁移能力。

Abstract

Objective

To investigate the expression of heparanase-2 (HPSE2) in gastric cancer tissues

and explore its effect on the survival and prognosis of the cancer and invasion and migration of the cancer cells.

Methods

Immunohistochemical staining of HPSE2 was performed on gastric cancer tissue chip to examine the expression level of HPSE2 in gastric cancer and paracancerous tissues. The correlation of HPSE2 expression level with clinical features

survival

prognosis and prognostic factors were analyzed. The lentival vectors of HPSE2 overexpression were constructed

and then transfected in gastric cancer cell lines SGC7901 and MKN28. The effect of HPSE2 overexpression on invasion and migration of gastric cancer cells were detected using Transwell analysis.

Results

The mean pathological score of HPSE2 was 4.56 in gastric cancer tissue

and 7.18 in paracancer tissues

showing that the expression was significantly lower in gastric cancer than paracancer tissues (

0.05). The expression level of HPSE2 was closely correlated with the tumor size

lymph node metastasis

and clinical staging. The patients with higher HPSE2 expression had obviously shorter median survival time and cumulative survival rate than those with lower expression (

0.05). Cox proportional risk model showed that clinical stage

tumor size and HPSE2 protein expression were risk factors for prognosis of gastric cancer patients (

0.05). Overexpression of HPSE2 could remarkably inhibit the invasion and migration of gastric cancer cells.

Conclusion

HPSE2 is lowly expressed in gastric cancer tissues

and is associated with the tumor size

lymph node metastasis

survival and prognosis of gastric cancer. Overexpression of HPSE2 could inhibit the invasion and migration of gastric cancer cells.
