肿瘤细胞的糖代谢调控与肿瘤治疗

Regulation of tumor cell glycometabolism and tumor therapy

肿瘤细胞具有独特的糖代谢特征,即高糖吸收、有氧糖酵解与高乳酸生成,具体表现为肿瘤细胞参与氧化代谢的相关蛋白表达下调、葡萄糖转运蛋白及单羧酸转运蛋白表达上调。研究表明,靶向肿瘤细胞糖代谢的药物具有杀死肿瘤细胞的能力,为肿瘤治疗带来了新希望。此外,肿瘤干细胞被认为是肿瘤复发、转移及预后不良的根源,其能量代谢特征目前尚不清楚。有研究表明,逆转肿瘤干细胞的能量代谢可以增加其化疗敏感性。本文综述近年来肿瘤细胞及肿瘤干细胞糖代谢方面的研究进展,以及通过靶向糖代谢进行肿瘤治疗面临的机遇与挑战,期望可为临床上肿瘤治疗提供新的思路与契机。

Tumor cells have unique energy metabolism phenomena, namely high glucose absorption, aerobic glycolysis and high lactic acid production, which are characterized by down-regulation of related proteins involved in oxidative metabolism in tumor cells, and up-regulation of glucose transporters and monocarboxylate transporters. Studies have shown that drugs that target tumor cell glucose metabolism have the ability to selectively kill tumor cells, bringing new hope for tumor treatment. Tumor stem cells are considered to be the root cause of tumor recurrence, metastasis and poor prognosis, and their energy metabolism characteristics have not yet been agreed. Studies have shown that reversing the energy metabolism of tumor stem cells can increase their chemosensitivity. This article reviews recent studies on tumor and tumor stem cell glucose metabolism and the opportunities and challenges of tumor treatment through targeting glucose metabolism, which might provide new ideas and opportunities for clinical tumor therapy.
