Abstract

In the present study, we found the mRNA expression level of glycerol-3-phosphate dehydrogenase (GPD1) was significantly downregulated in human breast cancer patients. Patients with reduced GPD1 expression exhibited poorer overall metastatic relapse-free survival ( = 0.0013). Further Cox proportional hazard model analysis revealed that the reduced expression of GPD1 is an independent predictor of overall survival in oestrogen receptor-positive ( = 0.0027, HR = 0.91, 95% CI = 0.85-0.97, = 3,917) and nodal-negative ( = 0.0013, HR = 0.87, 95% CI = 0.80-0.95, = 2,456) breast cancer patients. We also demonstrated that GPD1 was a direct target of miR-370, which was significantly upregulated in human breast cancer. We further showed that exogenous expression of GPD1 in human MCF-7 and MDA-MB-231 breast cancer cells significantly inhibited cell proliferation, migration, and invasion. Our results, therefore, suggest a novel tumour suppressor function for GPD1 and contribute to the understanding of cancer metabolism.

摘要

在本研究中，我们发现甘油-3-磷酸脱氢酶（GPD1）的mRNA表达水平在人类乳腺癌患者中显著下调。GPD1表达降低的患者表现出较差的总体无转移复发生存率（P = 0.0013）。进一步的Cox比例风险模型分析显示，GPD1表达降低是雌激素受体阳性（P = 0.0027，HR = 0.91，95% CI = 0.85 - 0.97，n = 3917）和淋巴结阴性（P = 0.0013，HR = 0.87，95% CI = 0.80 - 0.95，n = 2456）乳腺癌患者总体生存的独立预测因素。我们还证明GPD1是miR - 370的直接靶点，miR - 370在人类乳腺癌中显著上调。我们进一步表明，在人MCF - 7和MDA - MB - 231乳腺癌细胞中外源表达GPD1可显著抑制细胞增殖、迁移和侵袭。因此，我们的结果提示GPD1具有新的肿瘤抑制功能，并有助于对癌症代谢的理解。
