Ferroptosis, a non-apoptotic form of regulated cell death driven by iron-dependent lipid peroxidation, offers a mechanistically distinct opportunity to eliminate these refractory malignant states. In this review, we organize the field around three metabolic layers that govern ferroptosis in cancer: mobilizable iron pools and Fenton chemistry, lipid remodeling and membrane oxidation, and the dynamic balance between reactive oxygen species generation and antioxidant buffering. Rather than treating ferroptosis as a universal opportunity across all tumors, we emphasize how these layers create context-dependent liabilities in therapy-resistant disease. We then connect these layers to clinically relevant tumor contexts, including drug-tolerant persister cells, hypoxic solid tumors, and antioxidant-addicted cancer populations. Particular emphasis is placed on why lysosomal iron activation, lipid-droplet buffering, GSH/GPX4/FSP1 plasticity, medicinal chemistry, and nanomedicine-enabled delivery now represent major turning points in the field. By integrating mechanistic depth with translational challenges such as biomarker selection, intratumoral drug delivery, tumor-state heterogeneity, and therapeutic-window control, this review provides a cancer-therapy-oriented framework for the precision deployment of ferroptosis rather than a purely descriptive summary of ferroptosis biology.</p></div>","PeriodicalId":8062,"journal":{"name":"Apoptosis","volume":"31 6","pages":""},"PeriodicalIF":8.1,"publicationDate":"2026-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148051975","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}

Emerging evidence indicates that metabolic reprogramming and epigenetic alterations contribute to drug resistance, particularly through the evasion of ferroptosis, a regulated form of cell death characterised by lipid peroxidation. This study investigated the role of lactate-associated histone modifications in driving EGFR-TKI resistance. Resistant lung adenocarcinoma tissues and cell lines were analysed using transcriptomics, Cleavage Under Targets and Tagmentation (CUT&amp;Tag) profiling, and biochemical assays. Glycolytic activity, lactate accumulation, and ferroptosis-related lipid peroxidation were assessed, followed by genetic and pharmacological interventions and in vivo xenograft validation. Resistant cells exhibited enhanced glycolysis and lactate accumulation, with pathway analyses highlighting ferroptosis evasion as a key resistance-associated process. Consequently, histone H4 lysine 8 lactylation (H4K8la) was significantly elevated in resistant tissues and cells. Mechanistically, H4K8la was enriched at transcription start sites, particularly at the promoter of aldo-keto reductase family 1 member C1 (AKR1C1). This epigenetic modification profoundly suppressed ferroptosis and promoted drug resistance. Disrupting this H4K8la-AKR1C1 defence axis restored lipid peroxidation, increased ferroptotic sensitivity, and resensitised resistant cells to EGFR-TKIs, as confirmed in vivo.

AgNP-PEG-TC was synthesized and characterized for its physicochemical properties, drug-loading efficiency, and pH-responsive release behavior. Its antitumor effects were assessed in human neurofibroma cells, including selumetinib-resistant cells, and in normal Schwann cells by examining proliferation, apoptosis, migration, and invasion. In vivo therapeutic efficacy and biosafety were evaluated in neurofibroma xenograft models. Bulk RNA sequencing, lipidomics, and protein analyses were performed to investigate the underlying mechanisms. AgNP-PEG-TC demonstrated stable colloidal properties and successful pH-sensitive release. It selectively reduced neurofibroma cell growth, migration, and invasion while promoting apoptosis, with minimal effects on normal cells. In xenograft models, AgNP-PEG-TC significantly inhibited tumor growth and showed good biocompatibility. Multi-omics analyses indicated that its antitumor activity was associated with ACSL4 downregulation, remodeling of arachidonic-acid-enriched phospholipids, enhanced lipid peroxidation, and increased lipid-droplet accumulation, suggesting heightened ferroptosis susceptibility. Notably, AgNP-PEG-TC synergized with MEK inhibitors and restored antitumor responses in resistant neurofibroma cells. These findings establish a metabolism-nanotechnology synergy in which AgNP-PEG-TC-mediated ACSL4 inhibition and lipid metabolic reprogramming resensitize MEK inhibitor-resistant neurofibromas to therapy.

However, there is currently a lack of comprehensive analysis of the Neddylation pathway in hepatocellular carcinoma (HCC). We treated HCC cells with a Neddylation pathway inhibitor (MLN4924) to observe its effects on the biological functions of HCC cells. Additionally, we constructed a Neddylation-related risk score (NRS) in HCC. Subsequently, we assessed the clinical value of NRS in predicting the prognosis of HCC and the efficacy of immunotherapy. Finally, we investigated the role of Proteasome 26S Subunit, Non-ATPase 1 (PSMD1) in the malignant progression of HCC through in vivo and in vitro experiments. MLN4924 significantly inhibits the proliferation and migratory capacity of HCC cells, promotes apoptosis, and upregulates PD-L1 expression. Moreover, we have confirmed through in vivo and in vitro experiments that MLN4924 can enhance the sensitivity to Sorafenib. Additionally, we found that patients in the high NRS group have poor prognoses and are prone to developing resistance to treatments such as Sorafenib and Oxaliplatin, while being more sensitive to 5-Fluorouracil and immunotherapy. Finally, in both in vitro and in vivo experiments, it was found that knocking down PSMD1 can weaken the proliferation and metastatic capacity of HCC cells. Furthermore, knocking down PSMD1 can inhibit the levels of PD-L1 protein and NEDD8 protein that binds to Cullin in HCC cells. Mechanistically, we found that PSMD1 stabilizes the protein expression of β-catenin by inhibiting its degradation through the ubiquitin–proteasome system, thereby influencing the expression of PD-L1. In conclusion, this study reveals that Neddylation-related characteristics can effectively predict the prognosis and immunotherapy outcomes of HCC.
