目的

探讨果蝇Zeste基因增强子人类同源物(EZH2)在结肠癌的表达情况、评估对结直肠癌患者预后的意义,并分析预测与其相关的基因及细胞通路。

方法

通过GEO数据库下载基因芯片GSE17538数据内包含232例结直肠癌病例;结合R2平台,筛选出与EZH2表达显著相关的基因并进行GO和KEGG通路分析;通过Kaplan-Meier法绘制生存曲线,研究EZH2与患者预后、生存之间的关系。

结果

232例结肠癌标本中,EZH2的表达与年龄(χ2=4.426,P=0.035)、AJCC分期(χ2=8.259,P=0.041)和分化程度(χ2=7.301,P=0.026)有关,与性别(χ2=0.622,P=0.430)无关。全部检测出与EZH2表达显著相关基因共4 305个(其中正相关2 240个、负相关2 065个),对GO及KEGG通路分析后发现其中1 509个相关基因涉及细胞周期、RNA的转录、DNA复制等多个肿瘤发生、发展过程。Kaplan-Meier法分析,EZH2的表达与患者的无病生存期有相关性(P<0.05)。

结论

推测EZH2可成为研究患者预后的分子标志物,为未来深入研究提供参考。

Objective

The aim of this study was to investigate the prognosis value of the EZH2 expression and signatures during CRC and uncover their potential mechanisms in colorectal cancer.

Methods

The gene expression profiles of GSE17538 were downloaded from GEO database. The GSE17 538 data-set contained 232 samples. The data was combined by the R2 platform to search the genes which are associated with a significant expression with EZH2. The gene ontology(GO) and Kyoto Encyclopedia of Genes and Genomes pathway (KEGG) enrichment analyses were performed by R2 platform. The surival curves were estimated using the Kaplan-Meier method.

Results

In 232 cases, the expression of EZH2 in colorectal carcinoma was associated with age (χ2=4.426, P=0.035), AJCC stage (χ2=8.259, P=0.041) and differentiation (χ2=7.301, P=0.026), except for sex(χ2=0.622, P=0.430); In total, 4305 genes were identified which are associated with a significant expression with EZH2, including 2240 up-regulated genes and 2065 down-regulated genes. GO analysis and KEGG pathway analysis results showed that these were significantly enriched in biological processes , including proliferation in cell cycle, RNA transcription and DNA replication; Using the Kaplan-Meier method we found the expression of EZH2 is related with disease free survival .

Conclusion

EZH2 could be used as a potential prognostic marker and a therapeutic target in colorectal cancer.
