摘要:



文题释义:
铜死亡:是2022提出的铜离子浓度依赖性程序性细胞死亡方式。与凋亡、坏死、铁死亡等已知的细胞死亡方式不同,铜死亡的机制涉及三羧酸循环与氧化应激,通过干扰三羧酸循环和活性氧的积累发生蛋白毒性应激,最终导致疾病的发生发展。
三羧酸循环:也称柠檬酸循环,是细胞有氧呼吸的核心代谢途径,主要在线粒体中进行,是糖、脂肪和氨基酸三大代谢的枢纽,通过氧化乙酰辅酶A分解碳骨架生成ATP,为细胞代谢提供能量。近年来研究发现,铜死亡在三羧酸循环中的作用与细胞死亡密切相关。

背景:研究表明铜死亡在骨科疾病的发生发展和治疗中起关键作用,然而,铜死亡在骨科相关疾病中的调控作用和机制尚不明确。
目的:综述铜死亡在骨科相关疾病中的作用和机制。
方法:以“cuproptosis,copper steady state,osteoarthritis,osteoporosis,rheumatoid arthritis,osteosarcoma,oxidative stress”为英文检索词,检索PubMed数据库建库至2025年3月发表的相关文献,根据入选标准,最终纳入55篇文献进行综述。
结果与结论:在骨关节炎中,过量铜离子诱导金属调节转录因子1的表达,间接激活基质金属蛋白酶导致软骨基质的降解;同时,铜死亡通过干扰三羧酸循环和抑制谷氨酰胺代谢引发氧化应激,加速软骨细胞死亡。在骨质疏松中,铜死亡通过抑制成骨细胞的谷氨酰胺代谢和矿化功能、促进破骨细胞的分化,破坏骨形成与吸收的平衡。在类风湿关节炎中,铜离子通过激活磷脂酰肌醇3-激酶/蛋白激酶B/丝裂原活化蛋白激酶信号通路促进滑膜细胞异常活化和炎症因子释放,加剧关节破坏。在骨肉瘤中,高浓度铜离子通过靶向铁还原蛋白1诱导线粒体功能障碍和蛋白毒性应激,选择性杀伤肿瘤细胞。铜死亡在骨科疾病中的作用机制复杂多样,涉及多种细胞和信号通路。靶向铜死亡或其相关通路可能为骨科疾病的治疗提供新策略,如铜螯合剂或铜离子载体的应用,具有重要的临床潜力。未来研究需进一步探索铜死亡的具体调控机制及铜死亡在疾病治疗中的应用价值。

Abstract: BACKGROUND: Studies have shown that cuproptosis plays a critical role in the pathogenesis and treatment of orthopedic diseases. However, the regulatory roles and mechanisms of cuproptosis in orthopedic-related diseases remain unclear.
OBJECTIVE: To review the roles and mechanisms of cuproptosis in orthopedic-related diseases.
METHODS: A literature search was conducted in the PubMed database using the following English keywords: "cuproptosis," "copper steady state," "osteoarthritis," "osteoporosis," "rheumatoid arthritis," "osteosarcoma," and "oxidative stress." The search included publications up to March 2025. According to the inclusion criteria, 55 articles were finally included for review.
RESULTS AND CONCLUSION: In osteoarthritis, excessive copper ions induce the expression of metal-regulatory transcription factor 1, indirectly activating matrix metalloproteinases and leading to cartilage degradation. Cuproptosis disrupts the tricarboxylic acid cycle and inhibits glutamine metabolism, triggering oxidative stress and accelerating chondrocyte death. In osteoporosis, cuproptosis suppresses glutamine metabolism and mineralization in osteoblasts while promoting osteoclast differentiation, thereby disrupting the balance between bone formation and resorption. In rheumatoid arthritis, copper ions activate the phosphatidylinositol 3-kinase/protein kinase B/mitogen-activated protein kinase signaling pathway, promoting abnormal synovial cell activation and inflammatory cytokine release, which exacerbates joint destruction. In osteosarcoma, high concentrations of copper ions target ferredoxin 1, inducing mitochondrial dysfunction and proteotoxic stress to selectively kill tumor cells. The mechanisms of cuproptosis in orthopedic diseases are complex and multifaceted, involving diverse cell types and signaling pathways. Targeting cuproptosis or its associated pathways may offer novel therapeutic strategies for orthopedic disorders, such as the application of copper chelators or ionophores, demonstrating significant clinical potential. Future studies should further elucidate the precise regulatory mechanisms of cuproptosis and explore its translational value in disease treatment.
