Copper-induced cell death, called cuproptosis, is observed in malignant cells and is linked to aggregation of lipoylation proteins and activation of cell-death pathways under toxic copper excess. Cuproptosis-related gene expression differs between normal and tumor tissues and associates with oxidative stress control, immune responses, and tumor microenvironment composition. Activation of cuproptosis correlates with redox-metabolism regulators such as FDX1, LIAS, LIPT1, DLD, DLAT, PDHA1, and PDHB, suggesting copper signaling as a therapeutic target to improve immunotherapy outcomes.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":35,"@type":76,"position":81},"https://docshare.wps.com/document/healthcare/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/cuproptosis-the-novel-type-of-oxidation-induced-cell-death-in-thoracic-cancers-can-it-enhance-the-success-of-immunotherapy/336509/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/cuproptosis-the-novel-type-of-oxidation-induced-cell-death-in-thoracic-cancers-can-it-enhance-the-success-of-immunotherapy/336509.png","ImageObject",300,407,{"name":92,"@type":93},"Liam","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-23","2026-09-21",true,{"@type":102,"interactionType":103,"userInteractionCount":39},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What is cuproptosis and how does it relate to copper in thoracic cancers?","Question",{"text":112,"@type":113},"Cuproptosis is copper-induced cell death defined as a novel programmed cell death subtype observed in malignant cells.

Copper-related toxicity and dysbalanced metabolism were associated with the disruption of intracellular respiration and the development of various diseases, including cancer. Notably, copper-induced cell death was defined as cuproptosis which was also observed in malignant cells, representing an attractive anticancer instrument. Excess of intracellular copper leads to the aggregation of lipoylation proteins and toxic stress, ultimately resulting in the activation of cell death. Differential expression of cuproptosis-related genes was detected in normal and malignant tissues. Cuproptosis-related genes were also linked to the regulation of oxidative stress, immune cell responses, and composition of tumor microenvironment. Activation of cuproptosis was associated with increased expression of redox-metabolism-regulating genes, such as ferredoxin 1 (FDX1), lipoic acid synthetase (LIAS), lipoyltransferase 1 (LIPT1), dihydrolipoamide dehydrogenase (DLD), drol ipoamide S-acetyltransferase (DLAT), pyruvate dehydrogenase E1 subunit alpha 1 (PDHA1), and pyruvate dehydrogenase E1 subunit beta (PDHB)) . Accordingly, copper-activated network was suggested as an attractive target in cancer therapy. Mechanisms of cuproptosis and regulation of cuproptosis-related genes in different cancers and tumor microenvironment are discussed in this study. The analysis of current findings indicates that therapeutic regulation of copper signaling, and activation of cuproptosis-related targets may provide an effective tool for the improvement of immunotherapy regimens.  \nKey messages  \nFacts  \n• Copper ions, essential components of human body, can activate a novel subtype of programmed cell death, defined as cuproptosis.  \n†Ruiwen Zhao and Olga Sukocheva contributed equally to this work.  \n*Correspondence:  \nOlga Sukocheva [olga.sukocheva@sa.gov.au](olga.sukocheva@sa.gov.au)[ ](olga.sukocheva@sa.gov.au)Ruitai Fan [fccfanrt@zzu.edu.cn](fccfanrt@zzu.edu.cn)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2024.
