Cuproptosis is a recently identified form of regulated cell death in which copper binds to lipoylated mitochondrial proteins, promotes their aggregation, destabilises iron-sulfur cluster proteins, and induces mitochondrial proteotoxic stress. Copper therefore has context-dependent roles in cancer. Physiological copper supports tumour metabolism, angiogenesis, extracellular-matrix remodelling, and selected oncogenic signalling pathways, whereas therapeutic copper depletion can inhibit copper-dependent tumour processes. Conversely, copper ionophores and related approaches may increase intracellular copper sufficiently to induce cuproptosis in metabolically susceptible cancer cells. This review describes systemic and intracellular copper homeostasis, including intestinal absorption, intracellular trafficking, mitochondrial copper distribution, storage, and export. Particular attention is given to CTR1/SLC31A1, the functionally distinct copper-transporting ATPases ATP7A and ATP7B, metallothioneins, copper chaperones, and cytochrome c oxidase assembly factors. We also examine how cancer cells reprogramme copper handling to support proliferation, angiogenesis, metastasis, and immune evasion. Finally, we discuss the molecular basis of cuproptosis, including the roles of FDX1, FDXR, LIAS, DLAT, mitochondrial respiration, protein lipoylation, and iron-sulfur cluster destabilisation. Current evidence indicates that cuproptosis susceptibility varies among tumour types and depends on copper handling, mitochondrial metabolic state, and the integrity of the protein-lipoylation machinery. Defining these determinants will be necessary for the development of tumour-selective copper-targeted therapies.</p>","PeriodicalId":8062,"journal":{"name":"Apoptosis","volume":"31 9","pages":""},"PeriodicalIF":9.0,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148886313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Classical models described MOMP as a rapid, synchronous, all-or-none event leading to caspase activation and cellular demise. However, accumulating evidence now challenges this binary view, revealing that both MOMP and downstream caspase activity are threshold-dependent processes that can produce diverse non-lethal outcomes. Under specific conditions, cells can survive or recover from MOMP and downstream apoptotic signaling, fundamentally reshaping our understanding of cell fate decisions. Failed apoptosis and anastasis lie at the center of this paradigm shift, revealing unexpected plasticity in apoptotic outcomes. Failed apoptosis occurs when limited MOMP triggers sublethal yet sustained caspase activity, leading to DNA damage, chromosomal instability, and prolonged cellular reprogramming, thereby accelerating oncogenesis and tumor progression. In contrast, anastasis describes a remarkable recovery process in which cells rebound from late-stage apoptosis after the removal of apoptotic stimuli. Recovered cells exhibit acquired enhanced stress tolerance and oncogenic traits, raising concern about their role in therapy failure, cancer progression, and relapse. This review discusses the molecular mechanisms governing MOMP initiation and subsequent apoptotic signaling, with particular emphasis on new insights into the reversibility of apoptosis. It highlights the concepts of failed apoptosis and anastasis as adaptive responses that influence cell fate, integrating current research, experimental tools and challenges, and their physiological relevance and clinical implications. By describing these survival pathways, the review aims to enhance our understanding of the reversibility of apoptosis and emphasize its relevance to cancer progression, metastasis, and resistance to therapy.

Once viewed primarily as the terminal product of glycolysis, lactate is now recognized as a central metabolic intermediate, signaling molecule, and epigenetic substrate that reshapes intracellular and microenvironmental redox networks and thereby influences cell fate. Emerging evidence suggests that lactate exerts a context-dependent and bidirectional influence on the ferroptosis machinery. This regulation is mediated through four closely interconnected dimensions: lactate flux and concentration gradients, extracellular acidosis within the microenvironment, monocarboxylate transporter (MCT)-dependent transmembrane metabolic exchange, and site-specific histone and non-histone lactylation. This review systematically examines how lactate regulates ferroptosis in a context-dependent manner across different cell types, subcellular compartments, and disease microenvironments. In many tumors and stromal niches, lactate can act as a metabolic barrier that supports immunosuppression and ferroptosis resistance. By contrast, under specific stress conditions, dysregulated lactate flux may promote metabolic imbalance, epigenetic reprogramming, and increased ferroptotic vulnerability. We further summarize recent translational advances targeting the lactate-ferroptosis axis, including compartment-specific pharmacological strategies, emerging nanomedicine-based delivery platforms, and physical approaches for modulating the microenvironment. Although this framework provides a useful basis for therapeutic exploration, most current evidence remains preclinical.
