Background: Cytarabine (Ara-C) remains the cornerstone of remission-induction and consolidation chemotherapy for acute myeloid leukemia (AML) and related hematological malignancies. Despite more than six decades of clinical use, its multi-organ toxicity continues to be managed almost exclusively through dose attenuation and supportive care, with no approved upstream pharmacological prevention strategy available. Objectives: This scoping review aimed to systematically map the breadth and nature of pharmacological agents tested in vivo for their capacity to mitigate cytarabine-induced multi-organ toxicity, to characterize their mechanisms of action and organ targets, and to identify evidence gaps and agents with translational potential. Methods: The review was designed and reported in accordance with the PRISMA-ScR checklist. A structured electronic search was conducted across PubMed/MEDLINE, Scopus, Cochrane Library and Embase, and Web of Science from database inception to 15 July 2025. Eligible studies were restricted to full-text, peer-reviewed, English-language research involving in vivo mammalian models administered cytarabine as the principal toxin, with at least one pharmacological co-intervention and at least one quantitative or histopathological organ-injury outcome. Results: From 5701 retrieved records, 36 eligible in vivo mammalian studies (spanning 1964–2024) were identified. Included studies addressed neurotoxicity (n = 6), gastrointestinal mucositis (n = 9), ocular toxicity (n = 3), hepatotoxicity (n = 3), bone marrow suppression (n = 4), chemotherapy-induced alopecia (n = 5), and reproductive and developmental toxicity (n = 4). Five recurring mechanistic strategies were identified across the heterogeneous agents tested: redox buffering (N-acetylcysteine, α-lipoic acid, rutin, swertiamarin, α-tocopherol), mitochondrial preservation (betanin, thymoquinone, vitamin D, sodium zinc dihydrolipoylhistidinate [DHLHZn]), tissue-microenvironment reprogramming (apraglutide, BADGE, plerixafor, short-chain fatty acids, β-glucan), molecular antagonism (deoxycytidine, dCMP), and immunomodulation (lienal peptide, IL-1β, AHCC). Conclusions: This scoping review provides the first systematic cartography of pharmacological mitigation strategies for cytarabine-induced multi-organ toxicity. Five mechanistic pathways converge across eight organ systems, with apraglutide and N-acetylcysteine representing the most clinically translatable candidates. Plerixafor and PPARγ blockade by BADGE constitute high-priority candidates for bone marrow niche protection, while the deoxycytidine antagonism principle warrants formal pharmacokinetic evaluation. The complete absence of cardiotoxicity mitigation data defines the most critical gap for future research. Full article

Oxidative stress has been recognized as a repeatedly validated pathophysiological factor in schizophrenia, but its mechanistic role and translational relevance remain incompletely defined. Prior work has advanced redox dysregulation, neuroinflammation, and NMDA receptor hypofunction as a putative central hub in schizophrenia. This narrative review proposes an evidence-weighted redox–mitochondria–immune framework that integrates peripheral biomarkers, magnetic resonance spectroscopy, postmortem findings, and preclinical mechanisms while explicitly distinguishing established observations from candidate pathways. Existing studies support increased oxidative damage and altered antioxidant buffering in schizophrenia, particularly involving the glutathione system. However, these abnormalities are neither uniform across disease stages nor equally represented across patient subgroups, and may be markedly prominent only in certain biological subgroups. Mechanistically, redox imbalance may interact with mitochondrial bioenergetic deficits and innate immune signaling; however, pathway-specific links such as cGAS-STING activation, nitrosative/peroxynitrite stress, and GPx4-ferroptosis should currently be treated as testable extensions rather than validated human mechanisms in schizophrenia. Importantly, the pathological consequences of oxidative stress are unlikely to be cell-type neutral. Parvalbumin-positive interneurons and oligodendrocyte lineage cells are more vulnerable because of their high metabolic load, limited antioxidant buffering capacity, and lipid/iron-related susceptibility, thereby providing a mechanistic bridge to excitation–inhibition imbalance, myelin abnormalities, and reduced circuit synchrony. Microglial redox–inflammatory signaling may further exacerbate these processes. On the basis of this framework, we argue that the key for future research is not to continue demonstrating the universality of oxidative stress, but to improve the translational efficiency. Biomarker-guided stratification, stage-sensitive study designs, and cell-type-informed therapeutic strategies may therefore provide a more productive path toward redox-targeted interventions in schizophrenia.

Lactate was traditionally considered a metabolic by-product of anaerobic glycolysis, mainly associated with tissue hypoxia and muscle fatigue. However, increasing evidence has redefined lactate as a multifunctional metabolic intermediate and signaling molecule involved in exercise-induced systemic adaptations. During physical activity, circulating lactate levels rise markedly when skeletal muscle production exceeds systemic clearance, allowing lactate to act as an exercise-responsive metabolite, or exerkine, and as a mediator of cardiometabolic adaptation. In the cardiovascular system, lactate serves not only as an efficient substrate for myocardial energy production but also as a regulator of vascular tone, endothelial function, angiogenesis, inflammation, and cardiac remodeling. These effects occur through receptor-dependent and receptor-independent mechanisms, including activation of hydroxycarboxylic acid receptor 1 (HCAR1/GPR81), modulation of intracellular redox balance, and histone or non-histone protein lactylation. This review summarizes current evidence on lactate in cardiovascular physiology and disease, focusing on myocardial lactate metabolism, HCAR1/GPR81 signaling, protein lactylation, extracellular vesicle communication, gut microbiota interactions, and therapeutic implications in heart failure, atherosclerosis, and diabetic cardiomyopathy. Although lactate is also produced under resting, postprandial, and pathological conditions, exercise is characterized by the amplitude and kinetics of lactatemia, coordinated hormonal and hemodynamic responses, and transient high-concentration signaling. These features support exercise-derived lactate as a context-dependent cardiovascular exerkine. Full article

Background: Systemic arterial hypertension (SAH) induced by Nω-nitro-L-arginine methyl ester (L-NAME) is a well-established model characterized by nitric oxide (NO^●) synthase inhibition and vascular dysfunction. The transient receptor potential vanilloid 1 (TRPV1) regulates Ca²⁺ flux and may contribute to mitochondrial homeostasis. We hypothesized that TRPV1 activation modulates mitochondria function and attenuates cardiac damage during SAH. Methods: Hypertension was induced in Wistar rats by administration of L-NAME (200 mg/L) for 40 days. During the last four days, hypertensive animals received capsaicin (5 mg/kg/day), capsazepine (6 mg/kg/day), or their combination. Cardiac function was evaluated in isolated hearts using the Langendorff perfusion system. Myocardial tissue viability was assessed by triphenyltetrazolium chloride (TTC) staining, and mitochondrial function was evaluated by measuring respiratory control and apoptosis-related proteins. Results: Capsaicin treatment was associated with significant cardioprotective effects in hypertensive rats. Although the findings are consistent with a role of TRPV1 activation in mediating these effects, the partial protection observed with capsazepine suggests that TRPV1-independent mechanisms may also contribute. Conclusions: TRPV1 activation contributes to cardioprotection in SAH, likely through preservation of mitochondrial function and redox balance. However, additional mechanisms beyond TRPV1 modulation may also participate in the observed protective effects. Further studies—including direct assessment of mitochondrial Ca²⁺ flux and the use of more selective or genetic approaches—are currently underway to clarify the underlying mechanisms. Full article

Sedimentary manganese deposits are an important mineral resource and also play a significant role in restoring the ancient marine environment. The redox environment of the ocean during the Mesoproterozoic era has long been a subject of controversy. This paper takes a large-scale sedimentary manganese deposit in northwest China as the research object, attempting to analyze the changes in the marine environment during the Mesoproterozoic era and their impact on the Mn mineralization processes. In recent years, an exploration breakthrough has been made in the manganese deposits in the Annanba region on the southern margin of the Dunhuang block, NW China. The Qingshagou Mn deposit is the largest and most representative in the region. Geochemical characteristics show that the ores have low average ratios of Fe/Mn (<0.19), V/Cr (<1.20), V/(V+Ni) (<0.54), and Al/(Al+Fe+Mn) (<0.30) but high average ratios of U/Th (~0.95), and Y/Ho (~28). The Post-Archean Australian Shale (PAAS)-normalized rare earth element (REE) patterns exhibit that middle rare earth elements are slightly enriched with weak positive anomalies for both Y (0.93~1.01) and Ce (0.97~1.15) and weak negative anomalies for Eu (0.87~0.99). The δ¹³C_PDB value of the ore ranges from −13.4‰ to −23.3‰, which is consistent with the δ¹³C_PDB value range of organic matter. Synthesizing these findings, it is concluded that the Qingshagou Mn deposit formed in a suboxic to oxic environment, the ore-forming materials were primarily derived from a submarine hydrothermal system, and the changes in redox conditions promoted the Mn precipitation.

Traditional mineral drugs represent an underexploited reservoir of natural antitumor agents; however, their clinical translation has historically been hindered by poor bioavailability, non-specific biodistribution, and dose-limiting toxicity. This review comprehensively examines the pharmacological mechanisms and modern formulation strategies driving the renaissance of mineral-based oncology therapeutics. We highlight how mineral drugs exert potent anticancer effects through interconnected pathways, including regulated cell death (e.g., apoptosis, ferroptosis), cell-cycle arrest, and immunomodulation. Crucially, we evaluate recent advances in drug delivery systems, such as liposomes, polymeric nanoparticles, inorganic frameworks, and stimuli-responsive (e.g., pH, redox, enzyme) release systems that successfully overcome traditional pharmacological barriers. These bioengineering strategies not only improve solubility and tumor targeting but also significantly widen the therapeutic window, as evidenced by enhanced tumor suppression and reduced systemic toxicity in preclinical models. Despite this progress, challenges regarding in vivo chemical transformations and tumor heterogeneity remain. Ultimately, we propose a closed-loop “Composition–Mechanism–Delivery” design paradigm to guide future research, facilitating the translation of ethnopharmacological heritage into precision mineral-based therapeutics.

Autophagy-associated readouts in localized prostate cancer cannot be interpreted based on LC3, p62/SQSTM1, or LC3 puncta alone. In line with the concept of autophagy as a stress-response system, this review proposes a flux-aware, organelle-centered framework for assigning biological meaning to autophagy-related changes under disease-relevant stress. The framework integrates oxidative burden, lysosomal competence, selective autophagy, mitophagy, ferritinophagy, p62/SQSTM1-NRF2 signaling, ferroptosis-aware controls, and disease-stage context to distinguish four interpretive states: homeostatic quality control, adaptive tumor survival, blocked clearance, and stress-overload vulnerability. Flavonoid-associated responses are used as stress-test examples because they expose recurrent limitations in the field, including supraphysiologic exposures, limited metabolite realism, static-marker inflation, and insufficient assessment of lysosomal function. However, the framework is not restricted to dietary compounds; it applies to metabolic, pharmacological, inflammatory, androgen-related, radiation-associated, or therapy-induced perturbations in which autophagy-associated markers are altered without resolution of flux or organelle function. By linking autophagosome formation, cargo turnover, lysosomal acidification, redox buffering, and phenotype-level endpoints, this review defines a practical evidence hierarchy for interpreting autophagy in localized prostate cancer and for prioritizing translational vulnerabilities arising from organelle crosstalk. This contribution is primarily conceptual and is operationalized methodologically through flux-based evaluation criteria and translationally through disease-window-specific study-design recommendations.

Chronic coronary syndromes (CCSs) are increasingly recognized as complex immunometabolic vascular disorders in which coronary microvascular dysfunction (CMD), persistent low-grade inflammation, oxidative stress, and maladaptive cellular remodeling contribute to ischemic symptoms and adverse outcomes beyond epicardial stenosis. CMD represents a heterogeneous condition comprising both functional and structural endotypes and constitutes a major determinant of myocardial ischemia, heart failure progression, and adverse cardiovascular outcomes, even in the absence of obstructive coronary artery disease. Emerging evidence indicates that immunometabolic reprogramming of endothelial cells, vascular smooth muscle cells, and immune cells sustains microvascular dysfunction in CCSs. Metabolic shifts toward glycolysis, mitochondrial dysfunction, redox imbalance, and dysregulated lipid metabolism promote chronic inflammatory activation within the coronary microenvironment. Convergent mitochondrial stress (including NAD⁺ decline) and redox injury promote endothelial senescence and increase susceptibility to regulated cell death, progressively limiting vasodilatory reserve and predisposing to microvascular rarefaction. Pyroptosis and ferroptosis-like lipid peroxidation further exacerbate endothelial barrier disruption and inflammatory amplification. In parallel, inflammasome activation, iron-dependent lipid peroxidation, impaired autophagy, and endoplasmic reticulum stress form interconnected molecular networks that amplify vascular injury through self-reinforcing mechanisms. This narrative review integrates mechanistic and translational evidence linking immunometabolic dysregulation, mitochondrial stress, thromboinflammatory signaling, endothelial senescence, and regulated cell death to distinct CMD endotypes. We propose a systems-level framework in which coronary microvascular dysfunction is conceptualized as an immunometabolic vascular network disorder, with reduced coronary flow reserve (CFR)—often termed myocardial flow reserve (MFR) in PET studies—emerging as the integrative functional endpoint of these interacting molecular perturbations and a robust predictor of major cardiovascular events.

Burn wound healing is a complex and dynamic process involving coordinated regulation of inflammation, oxidative stress, angiogenesis, and tissue remodeling. Polygonum cuspidatum, a traditional Chinese medicinal herb widely used for trauma- and inflammation-related disorders, represents an important source of bioactive compounds for tissue repair. Piceatannol (PIC), a naturally occurring stilbene constituent of P. cuspidatum, possesses potent anti-inflammatory and antioxidant activities; however, its therapeutic potential in burn wound healing remains insufficiently understood. In the present study, the therapeutic effects and underlying mechanisms of topical PIC were investigated using a murine deep second-degree burn model combined with multiple skin-related cellular models, including keratinocytes, fibroblasts, endothelial cells, and macrophages. PIC markedly accelerated wound closure and improved histological architecture, as evidenced by reduced inflammatory infiltration, enhanced collagen organization, and increased neovascularization. Mechanistically, PIC suppressed NF-κB activation and modulated KEAP1/NRF2-associated redox signaling, thereby alleviating inflammation–oxidative stress crosstalk during wound healing. In keratinocyte–fibroblast co-culture systems, PIC inhibited fibroblast-to-myofibroblast transition, reduced α-smooth muscle actin (α-SMA) expression, and attenuated excessive collagen deposition, suggesting anti-fibrotic activity. In addition, PIC promoted endothelial tube formation through activation of the STAT3–VEGF signaling axis. Collectively, these findings demonstrate that PIC facilitates burn wound repair through coordinated anti-inflammatory, antioxidative, pro-angiogenic, and anti-fibrotic effects. This study provides pharmacological support for the therapeutic potential of P. cuspidatum-derived compounds in burn management and highlights PIC as a promising candidate for topical treatment of burn injuries.

Introduction: Fish skin is the first line of defense against the aquatic environment, acting as a physical, chemical, and immunological barrier. In addition to preventing pathogen entry, the skin and its mucus contribute to osmoregulation, innate immunity, and redox balance. Skin lesions—caused by mechanical damage, parasites, environmental stress, or handling—disrupt this barrier, increasing susceptibility to infections, inflammation, and production losses. Thus, efficient skin regeneration is essential for fish welfare and performance. Nutrition plays a key role in this process by providing substrates for epithelial repair, immune function, and antioxidant defense. Among dietary factors, zinc (Zn) is particularly important due to its involvement in cell proliferation, enzymatic activity, and maintenance of skin integrity. Objective: Our objective is to assess the effectiveness of image-based analysis in quantifying the skin healing process in Atlantic salmon fed diets supplemented with zinc. Methodology: The trial comprised three dietary treatments: a control diet with 42 mg Zn per kg (D1), and two diets supplemented up to 120 mg/kg of zinc, derived from inorganic (D2) or organic (D3) forms. Pit-tagged fish with an initial body weight (78 ± 0.1 g) were fed the diets for 75 days. After 15 days of experimental feeding, a standardized wound lesion (2.5 mm diameter × 0.5 mm depth) was inflicted in deeply anesthetized fish, with a disposable biopsy punch, in the dorsal area. After wound infliction, the fish resumed their normal feeding regime for the rest of the trial days. The progression of skin wound healing was assessed using standardized digital image analysis. High-resolution photographs of individual wounds were collected 8, 16, 24 and 32 days post-wounding. All images were acquired under standardized conditions with the inclusion of ArUco identifiers to enable a subsequent computer-assisted comparison. Morphometric parameters (wound width, diameter, perimeter and area) were used to assess wound contraction and closure over time. In parallel, a semi-quantitative visual scoring system was applied to each wound image to capture qualitative aspects of healing that are not fully described by morphometric data alone. Results: Full data analysis is currently underway, but the first results show beneficial effects of dietary zinc supplementation on the skin regenerative process. Conclusions: The combined use of objective digital measurements and standardized visual scoring enabled a comprehensive evaluation of wound healing progress, bridging quantitative tissue remodeling with biologically relevant phenotypic outcomes. This image-based framework provides a sensitive and reproducible approach for assessing dietary interventions targeting skin regeneration and barrier restoration in Atlantic salmon. Full article

Ionizing radiation induces reactive oxygen species (ROS) and inflammatory signaling that contribute to both therapeutic efficacy and normal tissue toxicity. While the effects of high-dose radiation are well characterized, responses to low-dose-rate radiation (LDRR) remain inconsistent and are not adequately explained by conventional linear dose–response models. To address this gap, we conducted a narrative review of recent experimental studies across multiple biological systems, including body fluids, joint microenvironments, and reproductive tissues, focusing on redox and immune-related responses under LDRR conditions (dose rates: 0.39–3.49 mGy/h). Literature was identified through PubMed/MEDLINE, Web of Science, and Google Scholar, with emphasis on studies published between 2015 and 2026. These studies demonstrate that LDRR elicits nonlinear, dose-dependent effects that vary across biological compartments and involve coordinated changes in oxidative stress, immune signaling, and metabolic regulation. Based on this synthesis, we propose a unifying framework of nonlinear redox–immune coupling, in which oxidative stress functions as a threshold-dependent regulator and immune responses follow a biphasic trajectory characterized by activation at lower dose rates and attenuation or adaptation at higher levels. These responses are strongly influenced by the local microenvironment, resulting in compartment-specific variability. This integrated perspective supports a shift from dose-centric to systems-level interpretations of radiation biology and provides a basis for improving biomarker development, risk assessment, and therapeutic strategies in chronic low-dose radiation exposure settings. Future research priorities include time-resolved mechanistic studies to define compartment-specific redox thresholds, validation of candidate biomarkers under identical multi-compartment experimental conditions (e.g., GSH/GSSG ratio, 8-OHdG, circulating cytokine panels including IL-10/TNF-α ratio), and integration of subject-specific biological variables (e.g., age, sex, and baseline redox capacity) into predictive models of LDRR response.

Copper ions (Cu²⁺) and intracellular biothiols are tightly coupled in cellular redox regulation, where copper–thiol coordination governs oxidative stress and metal homeostasis. However, analytical platforms capable of sequentially monitoring Cu²⁺ and biothiols within a single molecular system remain scarce. Herein, we report a coumarin-based fluorescent probe XDP that enables sequential ON–OFF–ON sensing of Cu²⁺ and biothiols through a coordination–competition mechanism. The imine (C=N) site of XDP selectively coordinates Cu²⁺, leading to fluorescence quenching arising from coordination-induced electronic perturbation and enhanced nonradiative decay. The probe exhibits a linear response toward Cu²⁺ over 1–80 μM with a detection limit of 0.108 μM. Subsequent competitive binding of biothiols (GSH, Cys, and Hcy) releases Cu²⁺ from the complex, thereby restoring fluorescence and enabling detection within 1–30 μM with submicromolar sensitivity. XDP also displays a large Stokes shift (135 nm), which minimizes spectral overlap and improves signal reliability. Notably, Cu²⁺ binding triggers a distinct color change that supports naked-eye detection and smartphone-based RGB quantification. The probe further enables visualization of Cu²⁺ and thiol-triggered signal recovery in living cells and zebrafish. This work establishes a versatile analytical platform for probing copper–thiol interactions in environmental and biological systems. Full article

Background: Glioblastoma (GBM) is the most aggressive primary brain tumor in adults and remains associated with poor prognosis despite multimodal treatment. Ferroptosis, an iron-dependent form of regulated cell death driven by lipid peroxidation and redox imbalance, has recently emerged as a potential therapeutic vulnerability in glioma. This review summarizes current knowledge on the molecular regulation of ferroptosis in glioma and discusses its implications for tumor progression, therapeutic resistance, and translational targeting. Methods: A structured narrative review of the literature was conducted using PubMed/MEDLINE, Scopus, and Web of Science databases. Experimental, translational, and clinically relevant studies investigating ferroptosis-related mechanisms and therapeutic strategies in glioma and GBM were qualitatively analyzed. Results: Ferroptosis in glioma is regulated by interconnected pathways involving iron metabolism, phospholipid remodeling, oxidative stress, and antioxidant defense systems, particularly the SLC7A11–glutathione–GPX4 axis. Additional protective mechanisms mediated by FSP1 and DHODH, together with regulatory networks involving NRF2, ATF4, p53, and hypoxia-related signaling, contribute to adaptive resistance to ferroptosis. Increasing evidence indicates that ferroptosis interacts bidirectionally with the glioma tumor microenvironment and may exert both antitumor and immunosuppressive effects. Preclinical studies further suggest that ferroptosis induction may enhance the efficacy of temozolomide, radiotherapy, and immunotherapy, although clinical translation remains limited by tumor heterogeneity, blood–brain barrier penetration, and resistance mechanisms. Conclusions: Ferroptosis represents a biologically plausible and therapeutically promising target in glioma. Improved understanding of ferroptosis regulation, tumor microenvironment interactions, and biomarker-guided therapeutic strategies may support the future development of more effective treatments for GBM.

Plant cytochrome P450 monooxygenases (CYPs) are valuable biocatalysts for the regioselective hydroxylation of aromatic compounds. However, their expression in bacterial hosts is hampered by poor solubility, membrane anchoring and the requirement for redox partners. In this work, we report the design and characterization of modular expression systems that enable the functional production of SbCYP82D1.1 from Scutellaria baicalensis (SbF6H) in Escherichia coli. Both independent expression and synthetic fusion systems were evaluated by combining a CYP with a compatible reductase (ATR2_tr from Arabidopsis thaliana) to catalyze the conversion of chrysin into baicalein. A combinatorial library of N-terminal variants, host strains, media, and induction strategies was constructed and screened. Among the tested host, E. coli DH 10-beta provided the highest product titers, particularly when cultures were supplemented with 5-aminolevulinic acid. Truncation of the native transmembrane anchor significantly improved catalytic performance, whereas the addition of the heterologous MALLLAVF tag decreased activity. Fusion systems outperformed separate expression formats, showing approximately two-fold higher activity, with the flexible glycine–serine linker (L_GS) supporting the highest hydroxylation product formation. The corresponding fusion construct showed an apparent conversion of 0.1 mM chrysin to baicalein of up to 90% under the applied whole-cell reaction and analytical conditions, although this value should be interpreted with caution due to the concurrent instability of baicalein observed in all reactions and culture conditions. This result nevertheless indicates a marked improvement in whole-cell baicalein formation compared with previously reported bacterial systems. Together, these results demonstrate that rational N-terminal engineering combined with fusion protein design can enable efficient bacterial expression of plant CYPs, representing a promising step toward scalable production of hydroxylated flavonoids.

Prostate cancer remains a major therapeutic challenge, particularly after progression to castration-resistant disease, where persistent androgen receptor signaling, metabolic adaptation, immune escape, and treatment resistance jointly limit clinical benefit. Regulated cell death (RCD) is increasingly recognized not only as an endpoint of tumor cell elimination but also as a dynamic regulator of prostate cancer progression, therapeutic vulnerability, and tumor–immune interactions. In this review, we propose an immunometabolic framework in which androgen receptor signaling, lipid and redox metabolic reprogramming, oxidative stress, and therapeutic pressure converge to shape the susceptibility of prostate cancer cells to distinct RCD modalities. We focus on autophagy and ferroptosis as two extensively studied and translationally relevant pathways, while also discussing emerging roles of necroptosis, pyroptosis, and cuproptosis. Particular attention is given to how RCD-associated signals, including damage-associated molecular patterns, inflammatory mediators, and lipid peroxidation products, may remodel the tumor immune microenvironment and influence the transition between immune-cold and immune-inflamed phenotypes. We further summarize RCD-targeted therapeutic strategies, including ferroptosis induction, autophagy inhibition, nanodrug delivery systems, rational combination therapy, and biomarker-guided patient stratification. Finally, we discuss key translational barriers, including context-dependent biological effects, limited clinical validation, tumor heterogeneity, adaptive resistance, and insufficient predictive biomarkers. By integrating cell death biology with metabolic reprogramming, immune remodeling, and therapeutic resistance, this review highlights RCD as a promising but context-dependent therapeutic vulnerability in advanced prostate cancer.
