摘要：
Illumina microarray was used to identify differentially expressed genes in three epithelial ovarian cancer (EOC) cells. To validate themicroarray data, mRNA and protein level of glucose transporter-1 (GLUT-1) was examined. GLUT-1 had an EOC/normal cells ratio of 5.51 based on microarray. Real-time PCR and immunohistochemistry demonstrated that GLUT-1 expression was significantly increased in EOC (p=.029 and p<.001, respectively). On survival analysis, GLUT-1 overexpression (HR= 4.80, p=.027) and lymph nodemetastases (HR= 8.35, p=.016) conferred a significantly worse overall survival. In conclusion, GLUT-1 expression is remarkably upregulated in EOC and predicts a poor overall survival.
