氨基酸(AA)代谢在许多细胞过程中起着重要的作用,包括能量产生、免疫功能以及嘌呤和嘧啶的合成。因此,癌细胞需要增加对AA的摄取,并进行代谢重新编程,以满足与其快速增殖相关的能量需求。像许多其他癌症一样,髓系白血病很容易受到针对代谢依赖的特定治疗策略的影响。在此,我们的综述提供了一个全面的概述和TCGA数据分析的非必需的AA合成所需的生物合成酶及其在髓系白血病中的失调。此外,我们还讨论了AA感知的一般控制不可降压2(GCN2)和非哺乳动物雷帕霉素靶点(MTOR)通路在代谢易感性和耐药性中的作用。
Amino acid (AA) metabolism plays an important role in many cellular processes including energy production, immune function, and purine and pyrimidine synthesis. Cancer cells therefore require increased AA uptake and undergo metabolic reprogramming to satisfy the energy demand associated with their rapid proliferation. Like many other cancers, myeloid leukemias are vulnerable to specific therapeutic strategies targeting metabolic dependencies. Herein, our review provides a comprehensive overview and TCGA data analysis of biosynthetic enzymes required for non-essential AA synthesis and their dysregulation in myeloid leukemias. Furthermore, we discuss the role of the general control nonderepressible 2 (GCN2) and-mammalian target of rapamycin (mTOR) pathways of AA sensing on metabolic vulnerability and drug resistance.
