半胱氨酸代谢途径调控与肿瘤治疗新策略

Regulation of cysteine metabolism and new strategies for cancer treatment

  • 摘要: 肿瘤细胞通过代谢重编程满足其特殊的物质和能量需求。现有肿瘤代谢重编程研究以糖代谢研究为主,而氨基酸代谢在肿瘤细胞的增殖、迁移、侵袭方面也发挥了重要作用,是肿瘤能量代谢研究的新兴热点。半胱氨酸是一种生糖氨基酸,其代谢途径涉及多种酶和产物,可调节诸如氧化应激、能量代谢和细胞自噬等生理和病理过程。本文从肿瘤细胞中半胱氨酸的外源转运和内源性转化途径、半胱氨酸代谢途径对肿瘤发生发展的多种调控机制以及基于半胱氨酸代谢途径的潜在治疗靶点等方面进行了综述,为肿瘤临床用药提供理论依据。

     

    Abstract: In order to sustain prodigious anabolic needs, tumor cells need metabolic reprogramming that differs from untransformed somatic cells.Besides glucose metabolism in tumor, amino acid metabolism also plays an important role in tumor cell proliferation, migration, and invasion.It is an emerging trend in tumor energy metabolism research.The metabolic pathway of cysteine, a glucose-producing amino acid, involves a variety of enzymes and products, regulating physiological and pathological processes such as oxidative stress, energy metabolism, and autophagy.This article focuses on the exogenous transport and endogenous conversion pathways of cysteine in tumor cells, the various regulatory mechanisms of cysteine metabolism pathways on the occurrence and development of tumors, and the potential therapeutic targets based on cysteine metabolism pathways, which can provide a theoretical basis for clinical use of drugs against tumors.
