Cancer cells reprogram glucose metabolism to meet their malignant proliferation needs and survival under a variety of stress conditions. The prominent metabolic reprogram is aerobic glycolysis, which can help cells accumulate precursors for biosynthesis of macromolecules. In addition to glycolysis, recent studies show that gluconeogenesis and TCA cycle play important roles in tumorigenesis. Here, we provide a comprehensive review about the role of glycolysis, gluconeogenesis, and TCA cycle in tumorigenesis with an emphasis on revealing the novel functions of the relevant enzymes and metabolites. These functions include regulation of cell metabolism, gene expression, cell apoptosis and autophagy. We also summarize the effect of glucose metabolism on chromatin modifications and how this relationship leads to cancer development. Understanding the link between cancer cell metabolism and chromatin modifications will help develop more effective cancer treatments.
癌细胞会重新编程葡萄糖代谢,以满足其在各种应激条件下的恶性增殖需求和生存需要。显著的代谢重编程是有氧糖酵解,它可以帮助细胞积累用于生物大分子生物合成的前体。除了糖酵解,最近的研究表明糖异生和三羧酸循环在肿瘤发生中也起着重要作用。在这里,我们全面综述了糖酵解、糖异生和三羧酸循环在肿瘤发生中的作用,重点揭示相关酶和代谢物的新功能。这些功能包括调节细胞代谢、基因表达、细胞凋亡和自噬。我们还总结了葡萄糖代谢对染色质修饰的影响以及这种关系如何导致癌症发展。了解癌细胞代谢与染色质修饰之间的联系将有助于开发更有效的癌症治疗方法。
