Anomalous expression of glucose transporters (GLUTs) has been observed in a variety of tumor tissues. Although GLUT factors have been shown to have prognostic value for some cancer types, detailed bioinformatics investigation of the factors contributing to the prognostic prediction for patients with breast cancer (BC) has not yet been performed.
In this study, we examined the transcription levels of , , and and their associations with prognostic clinical data in patients with BC from the ONCOMINE database, using gene expression profiling interactive analysis (GEPIA), Kaplan-Meier (KM) plotter, and cBioPortal online tools.
The transcription level of was significantly higher in the BC samples than in the normal tissues, whereas the levels of and were lower in the BC samples. The expression levels of and were associated with the cancer clinical stage. Consistently, survival analysis demonstrated that a high expression level of was associated with low relapse-free survival (RFS) in patients with BC, whereas high and levels predicted a longer RFS in these patients.
Overall, these results suggest as an effective target of precision therapy, while are novel biomarkers for the prognosis of patients with BC.
在多种肿瘤组织中均观察到葡萄糖转运蛋白(GLUTs)的异常表达。尽管已表明GLUT因子对某些癌症类型具有预后价值,但尚未对影响乳腺癌(BC)患者预后预测的因素进行详细的生物信息学研究。
在本研究中,我们使用基因表达谱交互式分析(GEPIA)、Kaplan-Meier(KM)绘图仪和cBioPortal在线工具,从ONCOMINE数据库中检查了BC患者中、和的转录水平及其与预后临床数据的关联。
BC样本中的转录水平显著高于正常组织,而BC样本中的和水平较低。和的表达水平与癌症临床分期相关。同样,生存分析表明,高表达水平与BC患者的无复发生存期(RFS)低相关,而高和水平预测这些患者的RFS更长。
总体而言,这些结果表明是精准治疗的有效靶点,而和是BC患者预后的新型生物标志物。
