Wang C, Ye P, Chen M, Li R, Wen Y, Wang Y, Tong X, Dong C, Shi S. Reducing the availability of endogenous copper and glucose for cascade starvation therapy and chemodynamic therapy. Mater Today Bio 2025; 32:101702. [PMID: 40230642 PMCID: PMC11995123 DOI: 10.1016/j.mtbio.2025.101702] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2025] [Revised: 03/14/2025] [Accepted: 03/23/2025] [Indexed: 04/16/2025] Open
Abstract
The rapid growth of tumors relies heavily on a continuous supply of essential nutrients, including glucose and copper. Disrupting the nutrient supply to tumors has become an increasingly focal point in tumor therapy. However, solely blocking the energy supply typically only hinders further tumor growth and may not effectively eliminate existing tumor cells. Herein, a multifunctional cascade nanoreactor (HPP/TPEN@GC) endowed with N, N, N', N'-tetrakis(2-pyridinylmethyl)-1,2-ethanediamine (TPEN, a copper chelator) and glucose oxidase (GOx) is designed to disrupt both glycolysis and mitochondrial metabolism, which further induce cascade chemodynamic therapy (CDT). HPP/TPEN@GC can react with endogenous copper and glucose, thereby reducing their availability. The absence of copper prevents proper assembly and function of mitochondrial complex IV (CIV), hindering mitochondrial metabolism; the lack of glucose cuts off glycolysis and leads to a tumor specific starvation. Meanwhile, the reactions catalyzed by HPP/TPEN@GC contribute to the generation of Fenton-like catalysts and hydrogen peroxide (H2O2), which can further react to produce highly toxic hydroxyl radical (·OH) for CDT. Taken together, the multifunctional cascade nanoreactor reduces the availability of endogenous copper and glucose, and further takes advantage of them to generate ·OH for cascade starvation-chemodynamic therapy. Collectively, this work represents a distinctive therapeutic paradigm to harness endogenous copper and glucose, which should inspire further studies to take full advantage of endogenous nutrients to combat various diseases, including tumors.

Liu X, Huang L, Zhu Y, Wu P. Elemental comparative analysis of 18 elements reveal distinct patterns in benign and malignant thyroid tissues. Biometals 2025; 38:873-886.

Abstract
This study aims to compare variations in 18 trace elements (Al, Na, K, Mg, Ca, Ti, Ba, Sn, Cr, Mn, Fe, Cu, Zn, Se, Mo, Cd, Sr, and Tl) between benign and malignant thyroid tissues. Post-operative thyroid tissue samples were collected from 106 patients (34 benign, 72 malignant), and elemental concentrations were quantified using inductively coupled plasma mass spectrometry. Spearman's correlation analysis revealed positive correlations among these trace elements. Notably, the malignant group exhibited significantly higher concentrations in eight elements (Mg, Al, Fe, Cr, Ti, Sr, Sn, and Ba) compared to the benign group, while levels of six elements (Na, Mn, Cu, Zn, Cd, and Mo) were significantly lower. Orthogonal partial least squares discriminant analysis distinguished three elements (Al, Ti, Sn) for the malignant group and six elements (Na, Mn, Cu, Zn, Cd, and Mo) for the benign group. Multivariate logistic regression further revealed associations between thyroid cancer and levels of Al, Cr, Ti, Sr, Sn, Ba, Mn, Cu, Zn, and Cd. Considering with each elemental biological funcions, these findings suggest that Cu, Mn, and particularly Zn may act as essential antitumor elements with synergistic effects, whereas elevated Ba, Cr, and Al levels are closely related to thyroid malignancies. However deficiencies and excesses of elements may be the consequences of malignant tissues. In conclusion, benign and malignant thyroid tumors exhibit different trace-element profiles.

Liposomal nanoformulations of novel copper-based complexes exhibiting antimelanoma activity - In vitro and in vivo validation. Int J Pharm 2025; 677:125643.

Abstract
Melanoma stands as the most aggressive form of skin cancer. The lack of effective and safe therapies has led to the investigation of innovative strategies. The present work validates the in vitro and in vivo antimelanoma activity of new copper complexes of 8-hydroxyquinoline (8HQ) derivatives in free or liposomal forms. Firstly, the cytotoxic properties of several copper-based complexes were screened towards human (A375) and murine (B16F10) melanoma cell lines and human dermal fibroblasts or keratinocytes (HaCaT) cell lines. All the complexes presented lower IC50 values (<20 μM) than dacarbazine (DTIC) and temozolomide (TMZ), the positive controls (>80 μM). Aiming to solve low specificity against tumor cells and enhance its targetability to affected sites three metal-based complexes were selected, based on their antiproliferative properties, and incorporated in long blood circulating liposomes. One of them, di-2-(((2-morpholinoethyl)imino)methyl)quinolin-8-olCopper(II), designated as LCR35, was selected for further studies due to the highest incorporation parameters and cytotoxic properties observed. The antiproliferative activity of LCR35 was preserved after its association to liposomes. Moreover, in B16F10 cells this effect was potentiated. Furthermore, cell cycle analysis studies in A375 and B16F10 cell lines were performed to elucidate the mechanism of action of copper-based complex formulations. A cell cycle arrest at G2/M and G0/G1 phases in A375 and B16F10 cells, respectively, both in free and liposomal forms were observed. To validate the therapeutic potential of LCR35 two murine melanoma models were carried out: subcutaneous and metastatic. Pre-clinical studies demonstrated the high therapeutic effect of LCR35, especially after incorporation in liposomes, compared to control group or animals that received LCR35 Free and DTIC. Overall, in vitro and in vivo studies highlight the potential antimelanoma properties of the copper-based complex, LCR35.

Abstract
This primer aims to expose scientists who study the brain to the field of copper biology. We briefly discuss key copper homeostasis mechanisms and proteins and place these functions in the context of the brain and neurodevelopment. A small number of key copper genes are explored as representative examples of the importance of this metal to the brain. We show that these genes are expressed throughout the brain and their defects are linked to a diverse array of neurological phenotypes, which we discuss further in the context of several neurological and neurodegenerative diseases associated with dysregulation of copper. This review aims to expose interested scientists to the fundamental roles for copper in the brain, the primary proteins responsible for maintaining copper homeostasis in the brain, and the classic neurological diseases associated with this metal.

Abstract
Copper (Cu) is an essential metal micronutrient, and a fungal pathogen's ability to thrive in diverse niches across a broad range of bioavailable copper levels is vital for host colonization and fungal propagation. Recent transcriptomic studies have implied that trace metal acquisition is important for the propagation of the white nose syndrome (WNS) causing fungus, Pseudogymnoascus destructans, on bat hosts. This report characterizes the P. destructans transcriptional response to Cu-withholding and Cu-overload stress. We identify 583 differently expressed genes (DEGs) that respond to Cu-withholding stress and 667 DEGs that respond to Cu-overload stress. We find that the P. destructans Cu-transporter genes CTR1a and CTR1b, as well as two homologs to Cryptococcus neoformans Cbi1/BIM1 VC83_03095 (BLP2) and VC83_07867 (BLP3), are highly regulated by Cu-withholding stress. We identify a cluster of genes, VC83_01834 - VC83_01838, that are regulated by copper bioavailability, which we identify as the Cu-Responsive gene Cluster (CRC). We find that chronic exposure to elevated copper levels leads to an increase in genes associated with DNA repair and DNA replication fidelity. A comparison of our transcriptomic datasets with P. destructans at WNS fungal infection sites reveals several putative fungal virulence factors that respond to environmental copper stress.

Abstract
Copper, an essential micronutrient, plays significant roles in numerous biological functions. Recent studies have identified imbalances in copper homeostasis across various cancers, along with the emergence of cuproptosis, a novel copper-dependent form of cell death that is crucial for tumor suppression and therapeutic resistance. As a result, manipulating copper levels has garnered increasing interest as an innovative approach to cancer therapy. In this review, we first delineate copper homeostasis at both cellular and systemic levels, clarifying copper's protumorigenic and antitumorigenic functions in cancer. We then outline the key milestones and molecular mechanisms of cuproptosis, including both mitochondria-dependent and independent pathways. Next, we explore the roles of cuproptosis in cancer biology, as well as the interactions mediated by cuproptosis between cancer cells and the immune system. We also summarize emerging therapeutic opportunities targeting copper and discuss the clinical associations of cuproptosis-related genes. Finally, we examine potential biomarkers for cuproptosis and put forward the existing challenges and future prospects for leveraging cuproptosis in cancer therapy. Overall, this review enhances our understanding of the molecular mechanisms and therapeutic landscape of copper and cuproptosis in cancer, highlighting the potential of copper- or cuproptosis-based therapies for cancer treatment.

COMMUNICATIONS MEDICINE 2025; 5:158. [PMID: 40328936 PMCID: PMC12056176 DOI: 10.1038/s43856-025-00889-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2024] [Accepted: 04/29/2025] [Indexed: 05/08/2025] Open
Abstract
BACKGROUND Protein misfolding is a hallmark of aging, resulting in diabetes and neuroendocrine disorders. Insulin preparations also form aggregates known as insulin balls. Aggregated insulin preparations usually form amyloids and are stable in subcutaneous tissue, some specimens are cytotoxic to cultured cells. METHODS A multilayered structural analysis of the detailed morphology of 21 insulin balls was performed by connecting regions of interest along spatial axes. Gross and optical microscopic findings, Raman spectrometric analysis using formalin-fixed paraffin-embedded block specimens, matrix-assisted laser desorption/ionization-time of flight-mass spectrometry, microfocus X-ray computed tomography, scanning electron microscopy-energy dispersive X-ray spectroscopy analysis, and transmission electron microscopy analysis were performed. RESULTS Here, we show the presence of 100 µm Cu0 within an insulin ball removed from a woman in her mid-40s with diabetes. The insulin ball is made of insulin lispro in an insoluble state in the lower abdominal subcutaneous adipose tissue. Transmission electron microscopy reveals fibrous structures. Microfocus X-ray computed tomography detects many spots with strong light contrast in the insulin ball. Scanning electron microscopy-energy dispersive X-ray spectroscopic analysis shows that the largest light spot is elemental metallic copper without an oxidation state (Cu0). CONCLUSIONS The largest amount of Cu0 found in living things is in a human. Our discovery of 100 µm Cu0 within the insulin ball supports the idea that insulin preparations from outside can disrupt the balance of metals, including Cu. In 2025, the patient continues to inject subcutaneous insulin preparations, but no new insulin balls appear.

Analysis of transition metal content in glioblastoma reveals association between iron and survival. Transl Oncol 2025; 55:102376. [PMID: 40163909 PMCID: PMC11993186 DOI: 10.1016/j.tranon.2025.102376] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2024] [Revised: 03/15/2025] [Accepted: 03/24/2025] [Indexed: 04/02/2025] Open
Abstract
INTRODUCTION Little is known about the role of transition metals in glioblastoma progression. Here we investigated whether transition metal content is associated with glioblastoma outcomes. METHODS Tumor samples were obtained from 37 newly diagnosed patients with glioblastoma, 21 of which had matched plasma. Iron, zinc, manganese, and copper content in those samples was quantified via inductively-coupled mass spectrometry or atomic emission spectrometry, and subsequently analyzed for associations with overall survival. Multiplexed immune profiling was performed to determine whether transition metal content was associated with altered cytokine profiles. RESULTS Higher plasma iron levels were strongly associated with prolonged survival (Kaplan-Meier analysis: 30.15 months vs. 12.43 months, P = 0.0036; Multivariate Cox regression analysis: HR: 0.79 [0.64 - 0.97], P = 0.03). Zinc, manganese, and copper concentration in plasma or tumor and iron in tumor were not significantly associated with overall survival. Immune profiling of plasma and tumor samples revealed that plasma iron correlated with plasma IFN-β concentration (R = 0.63, P = 0.0057) in patients with glioblastoma. No correlation of plasma iron and IFN-β was observed in age- and sex- matched healthy individuals (R = -0.15, P = 0.153). Plasma transition metal concentration did not correlate with tumor transition metal concentration. Within tumors, manganese and zinc were correlated (R = 0.52, P = 0.0048) as well as copper and zinc (R = 0.36, P = 0.038). CONCLUSIONS Plasma iron is associated with survival in glioblastoma patients and may serve as a prognostic marker. The mechanisms underlying this association require further study.

Abstract
Dietary metal ions significantly influence the lifespan and reproduction of Drosophila females. In this study, we show that not adding any of the metal ions to the diet adversely affects reproduction and lifespan. By contrast, food with no added Zn negatively impacts reproduction but does not adversely affect maternal lifespan, indicating it can dictate resource reallocation between key fitness traits. Specifically, it indicates that female flies stop producing eggs to conserve their body Zn for somatic maintenance. Although these data show that flies can sense varying dietary Zn levels to adjust their physiology, they cannot maximise egg production when faced with a choice between food with no added Zn or food with sufficient Zn to support maximum reproduction. Nonetheless, they can choose to preferentially oviposit on Zn-containing food, perhaps indicating a strategy to assure offspring survival. We also uncovered a role for the white gene in sustaining high levels of egg viability when Zn is diluted in the diet. These insights into the role of dietary metal ions, particularly Zn, point to a central role for these dietary micronutrients to indicate environmental quality and so govern trade-offs between lifespan and reproduction in flies.

Abstract
Copper is a trace element which is essential for biological organisms, and its homeostatic balance is important for living organisms to maintain the normal function. When the copper homeostasis is disordered, the cellular function and structure will be disrupted. Excess copper cause oxidative stress and DNA damage in cells, thereby inducing regulated cell death such as apoptosis and necroptosis. Excess copper in mitochondria can bind to lipoylated proteins in the tricarboxylic acid (TCA) cycle and cause them to aggregate, resulting in proteotoxic stress and eliciting a novel cell death modality: cuproptosis. Cancer cells have a greater demand for copper compared to normal tissue, and high levels of copper ions are closely associated with tumour proliferation and metastasis. The anti-tumor mechanisms of copper include the production of oxidative stress, inhibition of the ubiquitin-proteasome system, suppression of angiogenesis, and induction of copper-dependent cell death. Targeting copper is one of the current directions in oncology research, including the use of copper ion carriers to increase intracellular copper levels to induce oxidative stress and cuproptosis, as well as the use of copper ion chelators to reduce copper bioavailability. However, copper complexes have certain toxicity, so their biosafety needs to be improved. Emerging nanotechnology is expected to solve this problem by utilizing copper-based nanomaterials (Cu-based NMs) to deliver copper ions and a variety of drugs with different functions, thereby improving the anti-tumor efficacy and reducing the side effects. Therefore, a thorough understanding of copper metabolic processes and the mechanism of cuproptosis will greatly benefit anti-tumor therapy. This review summarizes the processes of copper metabolism and the mechanism of cuproptosis. In addition, we discuss the current anti-tumor paradigms related to copper, we also discuss current nanotherapeutic approaches to copper mortality and provide prospective insights into the future copper-mediated cancer therapy.

Abstract
BACKGROUND Recent research has increasingly highlighted the significance of various forms of cell death in contributing to tumor heterogeneity and modulating anti-tumor immunity. However, the potential implications of cuproptosis-related genes (CRGs) in lung adenocarcinoma (LUAD) remains poorly explored. METHODS We conducted a comprehensive analysis of the expression profiles of 19 CRGs in LUAD based on The Cancer Genome Atlas (TCGA). Utilizing consensus clustering, we stratified the TCGA cohort into two distinct LUAD subtypes (Cluster 1 and Cluster 2). The expression of CDKN2A was further validated across multiple datasets, including TCGA, GEO, Cancer Cell Line Encyclopedia (CCLE), and the Human Protein Atlas (HPA). The prognostic value of the CDKN2A was evaluated through univariate, multivariate, and survival analyses. Gene set enrichment analysis (GSEA) was performed to elucidate the molecular mechanisms associated with the CDKN2A. Additionally, we assessed the levels of immune cell infiltration in LUAD using the CIBERSORT, ESTIMATE, and XCELL algorithms. RESULTS By systematically analyzing the genetic alterations of 19 CRGs in LUAD, we found 15 differentially expressed genes between LUAD and adjacent normal tissues. Subsequently, using the consensus clustering method, we classified LUAD patients into two molecular subtypes and cluster 2 had a poor prognosis. CDKN2A emerged as a key gene of interest, exhibiting elevated expression in LUAD and correlating with adverse patient outcomes. Moreover, immunoinfiltration analysis revealed differential levels of immune cell infiltration between the CDKN2A high and CDKN2A low expression groups. CONCLUSIONS Our findings indicate that CDKN2A may serve as an effective prognostic biomarker for LUAD and may offer valuable insights into potential immunotherapeutic strategies for these patients. CLINICAL TRIAL NUMBER Not applicable.

Abstract
A Schiff base fluorescent probe, HTT, based on a sulfonylhydrazone structure was designed and synthesized for the sensitive and selective detection of Cu2+. The probe HTT exhibits good anti-interference performance toward Cu2+ in the presence of a variety of metal ions. After the addition of Cu2+, it can quickly respond within 40 seconds, and the fluorescence detection limit is 1.10 nM. The coordination ratio of probe HTT and Cu2+ is 2 : 1, and the coordination reaction between CN, SO and Cu2+ limits the formation of hydrogen bonds between the hydroxyl group and CN, disrupting the spatial coplanar effect of the probe molecule and thereby inducing fluorescence quenching. The probes can be recovered and reused using EDTA for the detection of Cu2+. The probe was also applied to the successful monitoring of Cu2+ in living cells and real water samples.

Abstract
Copper is an essential enzyme cofactor in bacteria, but excess copper is highly toxic. Bacteria can cope with copper stress by increasing copper resistance and initiating chemorepellent response. However, it remains unclear how bacteria coordinate chemotaxis and resistance to copper. By screening proteins that interacted with the chemotaxis kinase CheA, we identified a copper-binding repressor CsoR that interacted with CheA in Pseudomonas putida. CsoR interacted with the HPT (P1), Dimer (P3), and HATPase_c (P4) domains of CheA and inhibited CheA autophosphorylation, resulting in decreased chemotaxis. The copper-binding of CsoR weakened its interaction with CheA, which relieved the inhibition of chemotaxis by CsoR. In addition, CsoR bound to the promoter of copper-resistance genes to inhibit gene expression, and copper-binding released CsoR from the promoter, leading to increased gene expression and copper resistance. P. putida cells exhibited a chemorepellent response to copper in a CheA-dependent manner, and CsoR inhibited the chemorepellent response to copper. Besides, the CheA-CsoR interaction also existed in proteins from several other bacterial species. Our results revealed a mechanism by which bacteria coordinately regulated chemotaxis and resistance to copper by CsoR.

Abstract
Copper (Cu) is an essential metal micronutrient, and a fungal pathogens' ability to thrive in diverse niches across a broad range of bioavailable copper levels is vital for host-colonization and fungal-propagation. Recent transcriptomic studies have implemented that trace metal acquisition is important for the propagation of the white nose syndrome (WNS) causing fungus, Pseudogymnoascus destructans , on bat hosts. This report characterizes the P. destructans transcriptional response to Cu-withholding and Cu-overload stress. We identify 583 differently expressed genes (DEGs) that respond to Cu-withholding stress and 667 DEGs that respond to Cu-overload stress. We find that the P. destructans Cu-transporter genes CTR 1a and CTR1 b, as well as two homologs to Cryptococcus neoformans Cbi1/BIM1 VC83_03095 (BLP2) and VC83_07867 (BLP3) are highly regulated by Cu-withholding stress. We identify a cluster of genes, VC83_01834 - VC83_01837, that are regulated by copper bioavailability, which we identify as the Cu Responsive gene Cluster (CRC). We find that chronic exposure to elevated copper levels leads to an increase in genes associated with DNA repair and DNA replication fidelity. A comparison of our transcriptomic data sets with P. destructans at WNS fungal infection sites reveals several putative fungal virulence factors that respond to environmental copper stress.

Abstract
The disruption of Cu homeostasis is associated with the pathogenesis of many diseases and can result in alterations in Cu isotope fractionation. Changes in the Cu isotope ratio (65Cu/63Cu) of body fluids and tissues have been observed in liver disorders, cancers, and other diseases, displaying diagnostic/prognostic potential. However, it is not entirely clear whether certain physiological or lifestyle factors may also influence the bodily Cu isotopic composition, potentially obfuscating the signature of the pathology. To ascertain whether differences exist between food products, the Cu isotopic composition of 29 significant dietary Cu sources has been determined for the first time. The general enrichment of Cu and its heavy isotope, 65Cu, in legumes, nuts, and seeds (major Cu sources in plant-based diets) was revealed, suggesting that individuals with plant-based diets may have a bodily Cu isotopic composition offset from that of individuals with omnivorous diets, thus requiring controlling for in study design.

Abstract
Thyroid cancer (THCA) is the most prevalent endocrine tumor, and its incidence continues to increase every year. However, the processes underlying the aggressive progression of thyroid cancer are unknown. We concentrated on the prognostic and biological importance of thyroid cancer cuproptosis-related genes in this investigation. Genomic and clinical data were obtained from the UCSC XENA website, and cuproptosis-related genes were obtained from the FerrDb website. We performed differential expression analysis and Cox regression analysis to identify possible predictive targets associated with thyroid cancer prognosis. To assess the role of CDKN2A in thyroid cancer and the ability to predict prognosis on the basis of the CDKN2A expression level, we performed immunohistochemical staining, survival analysis, immunological analysis, functional analysis, and clinical analysis with respect to CDKN2A gene expression. CDKN2A expression levels were found to be inversely correlated with thyroid cancer prognosis. Higher levels of CDKN2A expression were associated with higher T, N, and clinicopathological stage and more residual tumor cells. Through univariate and multivariate Cox regression analyses, the CDKN2A expression level was shown to be linked with thyroid cancer patients' overall survival (OS). Moreover, we discovered that CDKN2A expression was linked to a dysfunctional tumor immune microenvironment. The study shows that CDKN2A, a cuproptosis-related gene, can be used as a prognostic marker for thyroid cancer.

Abstract
Copper exposure poses potential detrimental effects on both public and ecosystem health. Spermidine, an antioxidant, has shown promise in reducing oxidative stress and inflammation within the liver. However, its specific role in mitigating copper-induced hepatic cuproptosis and disturbances in copper metabolism remains unexplored. Consequently, this research aims to investigate to examine the impact of spermidine on hepatic cuproptosis and the related disturbances in copper metabolism. In the study, we established a model of copper-induced liver toxicity by feeding C57BL/6 mice a high-copper diet for three months. Histopathological and biochemical analyses revealed that copper exposure induced hepatic inflammatory cell infiltration, hepatocyte degeneration, elevated levels of MDA, ROS, and Cu2+ accumulation in the liver, and increased ALT and AST activities in serum (p < .05). Regarding inflammation, copper exposure significantly increased serum levels of IL-1β, IL-6, and TNF-α (p < .05), upregulated TNF-α and IFN-γ expression, and downregulated IL-10 expression in the liver (p < .05). Meanwhile, copper exposure inhibited the expression of copper metabolism and Fe-S cluster-related proteins (p < .05). Exogenous spermidine administration effectively reduced ROS, MDA, and Cu2+ accumulation in the liver, while also decreasing ALT and AST activites, IL-1β, IL-6, and TNF-α levels in the serum (p < .05), and downregulated TNF-α and IFN-γ expression (p < .001). Additionally, spermidine combined with CuSO4 treatment significantly promotes the expression of copper metabolism and Fe-S cluster-related proteins, compared to the CuSO4 group (p < .05). In summary, spermidine reduces Cu2+ accumulation in the liver, alleviates hepatic cuproptosis, oxidative damage, and inflammation, and exerts a protective effect on the liver.

Abstract
Copper import to the bacterial cytoplasm has been underinvestigated as bacterial cuproenzymes are extracytoplasmic. However, copper must access the cytoplasm to interact with metal-dependent transcription factors. In particular, the multiple drug antibiotic resistance (mar) operon is induced by a copper signal, the source of which has not been established. Here we show that the Escherichia coli AZY operon, which encodes the copper-binding periplasmic proteins YobA and YebY and the putative copper importer YebZ, mediates copper uptake. Copper uptake by YebZ depends on two conserved histidine residues and is modulated by YobA and YebY. Moreover, the AZY proteins are necessary for activation of the mar operon and mediate resistance to multiple antibiotics in a copper-dependent fashion. AZY-like operons are widespread in gram-negative bacteria, suggesting that this previously unknown link between copper and antibiotic resistance is a general mechanism that may offer an alternative therapeutic target for multidrug resistance.

Abstract
High copper levels pose a risk to environmental and human health due to their toxicity and widespread industrial application, in which abnormal copper levels are associated with various diseases both in neurodegenerative diseases and plant growth. Thus, a turn-on fluorescent probe BBYD-Cu, based on donor-acceptor type structure, was designed and synthesized with easy preparations. BBYD-Cu can specifically recognized Cu2+ by 2-picolinic ester group, then released the fluorophore to enhance the fluorescent signals. With a detection limit of 31 nM, it displays extremely sensitive and precise Cu2+ detection. In addition, BBYD-Cu has the advantages of fast response speed (within 3 min), excellent selectivity and strong anti-interference ability for Cu2+. Significantly, the BBYD-Cu demonstrates superior detection and imaging performance even in intricate real-world environmental samples, biological nerve cells and plant soybean sprout root tissue.

Abstract
Neuroblastoma is a deadly pediatric cancer that originates from the neural crest and frequently develops in the abdomen or adrenal gland. Although multiple approaches, including chemotherapy, radiotherapy, targeted therapy, and immunotherapy, are recommended for treating neuroblastoma, the tumor will eventually develop resistance, leading to treatment failure and cancer relapse. Therefore, a firm understanding of the molecular mechanisms underlying therapeutic resistance is vital for the development of new effective therapies. Recent research suggests that cancer-specific modifications to multiple subtypes of nonapoptotic regulated cell death (RCD), such as ferroptosis and cuproptosis, contribute to therapeutic resistance in neuroblastoma. Targeting these specific types of RCD may be viable novel targets for future drug discovery in the treatment of neuroblastoma. In this review, we summarize the core mechanisms by which the inability to properly execute ferroptosis and cuproptosis can enhance the pathogenesis of neuroblastoma. Therefore, we focus on emerging therapeutic compounds that can induce ferroptosis or cuproptosis, delineating their beneficial pharmacodynamic effects in neuroblastoma treatment. Cumulatively, we suggest that the pharmacological stimulation of ferroptosis and ferroptosis may be a novel and therapeutically viable strategy to target neuroblastoma.

Abstract
Bacteria and fungi produce natural products that coordinate copper for a variety of functions. Many copper-binding natural products function as copper-chelating metallophores, or chalkophores, that scavenge copper from the environment to meet cellular needs. By contrast, some compounds sequester toxic levels of environmental copper to protect the producing microorganism. These copper-binding compounds often have antimicrobial activities as well. In recent years, a number of new copper-coordinating natural products have been reported, including both ribosomally and non-ribosomally synthesized molecules. There have also been significant advances in understanding the biosynthesis of these and previously known copper chelators, leading to the discovery of new enzyme families. This review summarizes the recently discovered copper-binding natural products, their biosynthetic pathways, and their functions. By highlighting key biosynthetic enzymes, we hope to inspire the discovery of new copper-coordinating natural products that may be used as therapeutics and antimicrobial agents.

Peripheral mitochondrial transplantation alleviates diabetes-associated cognitive dysfunction by suppressing cuproptosis. Brain Res Bull 2025; 222:111245. [PMID: 39924054 DOI: 10.1016/j.brainresbull.2025.111245] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2024] [Revised: 01/23/2025] [Accepted: 02/04/2025] [Indexed: 02/11/2025]
Abstract
Mitochondrial dysfunction and neuronal impairment are hallmark features of Diabetes-Associated Cognitive Dysfunction (DACD), mitochondrial transplantation is also a therapeutic intervention for DACD. However, the precise mechanism underlying its therapeutic effects are not fully elucidated. Given that imbalances in copper homeostasis and cuproptosis are associated with various neurodegenerative disorders and diabetic myocardial damage, we hypothesize a role for cuproptosis in the pathogenesis of DACD. We further propose that therapeutic peripheral mitochondrial transplantation may ameliorate DACD by reducing processes of cuproptosis. In this research, the study delved into the expression levels of cuproptosis-associated proteins FDX1, LIAS, and DLAT, as well as the copper content in both type 2 diabetes mellitus (T2DM) mice and primary neuronal cells exposed to high glucose and palmitic acid (HG/Pal). Furthermore, the cognitive capabilities of the mice were evaluated using a series of behavioral tests. The findings revealed that in primary neurons exposed to HG/Pal, the expression of copper levels was elevated, and the levels of FDX1, LIAS, and DLAT were reduced. Post-transplantation of platelet-derived mitochondria (Mito-Plt), a significant reversal of these biomarkers was noted, coincident with an improvement in cognitive deficits in T2DM mice. Significantly, the cuproptosis agonist elesclomol (ES) aggravated these alterations. In summary, the findings collectively suggest a causal connection between DACD and the development of cuproptosis in neurons. The use of exogenous Mito-Plt presents a promising therapeutic approach, capable of rescuing neurons from cuproptosis and thereby potentially alleviating DACD.

Abstract
Periodontitis is a significant global public health issue associated with the onset and progression of various systemic diseases, thereby requiring additional research and clinical attention. Although ferroptosis and cuproptosis have emerged as significant areas of research in the medical field, their precise roles in the pathogenesis of periodontitis remain unclear. We aim to systematically summarize the current research on ferroptosis and cuproptosis in periodontal disease and investigate the roles of glutathione pathway and autophagy pathway in connecting ferroptosis and cuproptosis during periodontitis. Further, we propose that a homeostatic imbalance of copper and iron, driven by periodontal pathogens, may contribute to elevated periodontal oxidative stress, representing a potential unifying link between ferroptosis and cuproptosis involved in periodontitis. This article presents a comprehensive overview of the molecular mechanisms underlying ferroptosis and cuproptosis in periodontitis, offering novel theoretical insights into its pathogenesis and potential therapeutic targets.

Abstract
Tuberculosis (TB) caused by Mycobacterium tuberculosis (M.tb) remains a global health crisis, with over 10 million people affected annually. Despite advancements in treatment, M.tb has developed mechanisms to evade host immune responses, complicating efforts to eradicate the disease. Two emerging cell death pathways, ferroptosis and cuproptosis, have been linked to TB pathogenesis. Ferroptosis, an iron-dependent form of cell death, is driven by lipid peroxidation and reactive oxygen species (ROS) accumulation. This process can limit M.tb replication by depleting intracellular iron and inducing macrophage necrosis. However, excessive ferroptosis may lead to tissue damage and aid bacterial dissemination. Cuproptosis, triggered by copper accumulation, disrupts mitochondrial metabolism, leading to protein aggregation and cell death. M.tb exploits both iron and copper metabolism to survive within macrophages, manipulating these processes to resist oxidative stress and immune responses. This review examines the roles of ferroptosis and cuproptosis in TB, discussing how M.tb manipulates these pathways for survival. While therapeutic strategies targeting these processes, such as ferroptosis inducers (Erastin, RSL3) and inhibitors (Ferrostatin-1) and copper ionophores (Disulfiram, Elesclomol) and chelators, show promise, the limited understanding of these pathways and potential off-target effects remains a significant challenge. Further exploration of these pathways may provide insights into the development of targeted therapies aimed at controlling M.tb infection while minimizing host tissue damage. By elucidating the complex interactions between ferroptosis, cuproptosis, and TB, future therapies could better address bacterial resistance and improve clinical outcomes.

Abstract
Recently study has found a new form of copper-dependent death called cuproptosis, which differs from apoptosis, ferroptosis, and necrosis. The main process of cuproptosis is copper directly combined with lipid-acetylated proteins in the TCA cycle of mitochondrial response, leading to the aggregation of lipid-acetylated proteins and the loss of Fe-S cluster proteins, resulting in mitochondrial dysfunction, and eventually causing cell death. Previous studies demonstrated that an imbalance in copper homeostasis exacerbates the pathological progression of Alzheimer's disease (AD) through the induction of oxidative stress, inflammatory response, and the accumulation of Aβ deposition and tau protein hyperphosphorylation. However, the underlying mechanisms remains to be elucidated. More importantly, research identifies the role of cuproptosis and further elucidates the underlying molecular mechanisms in AD. This review summarized the effects of copper metabolism on AD pathology, the characteristics and mechanism of cuproptosis and we discuss the significance of cuproptosis in the pathogenesis of AD.

Abstract
Cuproptosis, a newly defined cell death process, represents a novel modality with significant therapeutic potential in cancer treatment. Nevertheless, the modest concentration and transient half-life of copper ions in the bloodstream constrain their efficient delivery into tumor cells. In this study, a copper-based prussian blue nanostructure loaded with serine metabolic inhibitor (NCT-503@Cu-HMPB) is constructed for selectively inducing cuproptosis combined with disrupting serine metabolism. Released within the tumor cells, NCT-503 is found to inhibit cellular serine metabolism and GSH production, ultimately causing metabolic dysfunction, redox imbalance, and increased the formation of Cu+ that disrupts mitochondrial respiration chain, inducing lipoylated protein dihydrolipoamide S-acetyltransferase (DLAT) aggregation and consequential iron-sulfur cluster protein loss, which leads to proteotoxic stress and ultimately results in cell death. The findings provide a novel paradigm for tumor therapy based on cuproptosis and metabolic reprogramming, offering prospects for the development of innovative nanotherapeutic platforms in the future.

Abstract
Whereas genetic mutations can alter cell properties, nongenetic mechanisms can drive rapid and reversible adaptations to changes in their physical environment, a phenomenon termed 'cell-state transition'. Metals, in particular copper and iron, have been shown to be rate-limiting catalysts of cell-state transitions controlling key chemical reactions in mitochondria and the cell nucleus, which govern metabolic and epigenetic changes underlying the acquisition of distinct cell phenotypes. Acquisition of a distinct cell identity, independently of genetic alterations, is an underlying phenomenon of various biological processes, including development, inflammation, erythropoiesis, aging, and cancer. Here, mechanisms that have been uncovered related to the role of these metals in the regulation of cell plasticity are described, illustrating how copper and iron can be exploited for therapeutic intervention.

Abstract
Fluorescence imaging has been recognized as a powerful tool for the real-time detection and specific imaging of biomarkers within living systems, which is crucial for early diagnosis and treatment evaluation of major diseases. Over the years, significant advancements in this field have been achieved, particularly with the development of novel fluorescent probes and advanced imaging technologies such as NIR-II imaging, super-resolution imaging, and 3D imaging. These technologies have enabled deeper tissue penetration, higher image contrast, and more accurate detection of disease-related biomarkers. Despite these advancements, challenges such as improving probe specificity, enhancing imaging depth and resolution, and optimizing signal-to-noise ratios still remain. The emergence of artificial intelligence (AI) has injected new vitality into the designs and performances of fluorescent probes, offering new tools for more precise disease diagnosis. This review will not only discuss chemical modifications of classic fluorophores and in situ visualization of various biomarkers including metal ions, reactive species, and enzymes, but also share some breakthroughs in AI-driven fluorescence imaging, aiming to provide a comprehensive understanding of these advancements. Future prospects of fluorescence imaging for biomarkers including the potential impact of AI in this rapidly evolving field are also highlighted.

Abstract
Copper is an essential nutrient for sustaining vital cellular processes spanning respiration, metabolism, and proliferation. However, loss of copper homeostasis, particularly misregulation of loosely bound copper ions which are defined as the labile copper pool, occurs in major diseases such as cancer, where tumor growth and metastasis have a heightened requirement for this metal. To help decipher the role of copper in the etiology of cancer, we report a histochemical activity-based sensing approach that enables systematic, high-throughput profiling of labile copper status across many cell lines in parallel. Coppermycin-1 reacts selectively with Cu(I) to release puromycin, which is then incorporated into nascent peptides during protein translation, thus leaving a permanent and dose-dependent marker for labile copper that can be visualized with standard immunofluorescence assays. We showcase the utility of this platform for screening labile Cu(I) pools across the National Cancer Institute's 60 (NCI-60) human tumor cell line panel, identifying cell types with elevated basal levels of labile copper. Moreover, we use Coppermycin-1 to show that lung cancer cells with heightened activation of nuclear factor-erythroid 2-related factor 2 (NRF2) possess lower resting labile Cu(I) levels and, as a result, have reduced viability when treated with a copper chelator. This work establishes that methods for labile copper detection can be used to assess cuproplasia, an emerging form of copper-dependent cell growth and proliferation, providing a starting point for broader investigations into the roles of transition metal signaling in biology and medicine.

Peleg S, Meron S, Shenberger Y, Hofmann L, Gevorkyan-Airapetov L, Ruthstein S. Exploring the Gating Mechanism of the Human Copper Transporter, hCtr1, Using EPR Spectroscopy. Biomolecules 2025; 15:127. [PMID: 39858521 PMCID: PMC11763644 DOI: 10.3390/biom15010127] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2024] [Revised: 01/05/2025] [Accepted: 01/13/2025] [Indexed: 01/27/2025] Open
Abstract
Ctr1 is a membrane-spanning homotrimer that facilitates copper uptake in eukaryotic cells with high affinity. While structural details of the transmembrane domain of human Ctr1 have been elucidated using X-ray crystallography and cryo-EM, the transfer mechanisms of copper and the conformational changes that control the gating mechanism remain poorly understood. The role of the extracellular N-terminal domains is particularly unclear due to the absence of a high-resolution structure of the full-length hCtr1 protein and limited biochemical and biophysical characterization of the transporter in solution and in cell. In this study, we employed distance electron paramagnetic resonance to investigate the conformational changes of the extracellular N-terminal domain of full-length hCtr1, both in vitro and in cells, as a function of Cu(I) binding. Our results demonstrate that at specific Cu(I) concentrations, the extracellular chains move closer to the lumen to facilitate copper transfer. Additionally, while at these concentrations the intracellular part is penetrating the lumen, suggesting a ball-and-chain gating mechanism. Moreover, this phenomenon was observed for both reconstituted protein in micelles and in native cell membranes. However, the measured distance values were slightly different, suggesting that the membrane's characteristics and therefore its lipid composition also impact and even regulate the gating mechanism of hCtr1.

Abstract
Breast cancer is the most commonly diagnosed cancer worldwide. Metal metabolism is pivotal for regulating cell fate and drug sensitivity in breast cancer. Iron and copper are essential metal ions critical for maintaining cellular function. The accumulation of iron and copper ions triggers distinct cell death pathways, known as ferroptosis and cuproptosis, respectively. Ferroptosis is characterized by iron-dependent lipid peroxidation, while cuproptosis involves copper-induced oxidative stress. They are increasingly recognized as promising targets for the development of anticancer drugs. Recently, compelling evidence demonstrated that the interplay between ferroptosis and cuproptosis plays a crucial role in regulating breast cancer progression. This review elucidates the converging pathways of ferroptosis and cuproptosis in breast cancer. Moreover, we examined the value of genes associated with ferroptosis and cuproptosis in the clinical diagnosis and treatment of breast cancer, mainly outlining the potential for a co-targeting approach. Lastly, we delve into the current challenges and limitations of this strategy. In general, this review offers an overview of the interaction between ferroptosis and cuproptosis in breast cancer, offering valuable perspectives for further research and clinical treatment.

Abstract
The growing demand for sustainable platforms for biomolecule manufacturing has fuelled the development of plant-based production systems. Agroinfiltration, the current industry standard, offers several advantages but faces limitations for large-scale production due to high operational costs and batch-to-batch variability. Alternatively, here, we describe the CuBe system, a novel bean yellow dwarf virus (BeYDV)-derived conditional replicative expression platform stably transformed in Nicotiana benthamiana and activated by copper sulphate (CuSO4), an inexpensive and widely used agricultural input. The CuBe system utilizes a synthetic circuit of four genetic modules integrated into the plant genome: (i) a replicative vector harbouring the gene of interest (GOI) flanked by cis-acting elements for geminiviral replication and novelly arranged to enable transgene transcription exclusively upon formation of the circular replicon, (ii) copper-inducible Rep/RepA proteins essential for replicon formation, (iii) the yeast-derived CUP2-Gal4 copper-responsive transcriptional activator for Rep/RepA expression, and (iv) a copper-inducible Flp recombinase to minimize basal Rep/RepA expression. CuSO4 application triggers the activation of the system, leading to the formation of extrachromosomal replicons, expression of the GOI, and accumulation of the desired recombinant protein. We demonstrate the functionality of the CuBe system in N. benthamiana plants expressing high levels of eGFP and an anti-SARS-CoV-2 antibody upon copper treatment. Notably, the system is functional in post-harvest applications, a strategy with high potential impact for large-scale biomanufacturing. This work presents the CuBe system as a promising alternative to agroinfiltration for cost-effective and scalable production of recombinant proteins in plants.

Abstract
Metals are vital in human physiology, which not only act as enzyme catalysts in the processes of superoxide dismutase and glucose phosphorylation, but also affect the redox process, osmotic adjustment, metabolism and neural signals. However, metal imbalances can lead to diseases such as diabetes, which is marked by chronic hyperglycemia and affects wound healing. The hyperglycemic milieu of diabetes impairs wound healing, posing significant challenges to patient quality of life. Wound healing encompasses a complex cascade of hemostasis, inflammation, proliferation, and remodeling phases, which are susceptible to disruption in hyperglycemic conditions. In recent decades, metals have emerged as critical facilitators of wound repair by enhancing antimicrobial properties (e.g., iron and silver), providing angiogenic stimulation (copper), promoting antioxidant activity and growth factor synthesis (zinc), and supporting wound closure (calcium and magnesium). Consequently, research has pivoted towards the development of metal ion-based therapeutics, including innovative formulations such as nano-hydrogels, nano-microneedle dressings, and microneedle patches. Prepared by combining macromolecular materials such as chitosan, hyaluronic acid and sodium alginate with metals, aiming at improving the management of diabetic wounds. This review delineates the roles of key metals in human physiology and evaluates the application of metal ions in diabetic wound management strategies.

Abstract
Previous studies have proved trace mineral disorders to be related to changes in oxidative stress, inflammatory state, and immune response in asthmatics. However, there is a scarcity of studies that examine the correlation between copper intake with mortality in asthmatic people. The aim of this research was to investigate the effect of copper intake on the asthmatic population's mortality. This investigation included 3175 individuals from the NHANES. Multiple statistical models were used in this investigation to discuss the correlation between copper intake and the asthmatic population's mortality. These models included Cox proportional hazards models, trend tests, restricted cubic splines (RCS), threshold effect model, and CoxBoost model. Three Cox hazard models showed an inverse relationship between copper intake and the risk of death in asthmatics. Statistical tests, such as trend tests, RCS models, and threshold effect models, proved an inverse and linear link between dietary copper and the risk of death. Through Kaplan-Meier analysis, asthmatic adults who had higher copper intake had a higher survival rate compared to asthmatics with lower copper intake. The CoxBoost model indicated that the intake of copper, selenium, and zinc had a protective effect on mortality, whereas iron was associated with an increased risk of death. The research proved an inverse and linear correlation between dietary copper intake and the risk of death among asthmatic people. Improving copper intake may have a positive impact on the long-term survival of individuals with asthma.

Abstract
Copper (Cu) is essential for brain development and function, yet its overload induces neuronal damage and contributes to neurodegeneration and other neurological disorders. Multiple studies demonstrated that Cu neurotoxicity is associated with mitochondrial dysfunction, routinely assessed by reduction of mitochondrial membrane potential. Nonetheless, the role of alterations of mitochondrial dynamics in brain mitochondrial dysfunction induced by Cu exposure is still debatable. Therefore, the objective of the present narrative review was to discuss the role of mitochondrial dysfunction in Cu-induced neurotoxicity with special emphasis on its influence on brain mitochondrial fusion and fission, as well as mitochondrial clearance by mitophagy. Existing data demonstrate that, in addition to mitochondrial electron transport chain inhibition, membrane damage, and mitochondrial reactive oxygen species (ROS) overproduction, Cu overexposure inhibits mitochondrial fusion by down-regulation of Opa1, Mfn1, and Mfn2 expression, while promoting mitochondrial fission through up-regulation of Drp1. It has been also demonstrated that Cu exposure induces PINK1/Parkin-dependent mitophagy in brain cells, that is considered a compensatory response to Cu-induced mitochondrial dysfunction. However, long-term high-dose Cu exposure impairs mitophagy, resulting in accumulation of dysfunctional mitochondria. Cu-induced inhibition of mitochondrial biogenesis due to down-regulation of PGC-1α further aggravates mitochondrial dysfunction in brain. Studies from non-brain cells corroborate these findings, also offering additional evidence that dysregulation of mitochondrial dynamics and mitophagy may be involved in Cu-induced damage in brain. Finally, Cu exposure induces cuproptosis in brain cells due mitochondrial proteotoxic stress, that may also contribute to neuronal damage and pathogenesis of certain brain diseases. Based on these findings, it is assumed that development of mitoprotective agents, specifically targeting mechanisms of mitochondrial quality control, would be useful for prevention of neurotoxic effects of Cu overload.

Abstract
Programmed cell death represents a precisely regulated and active cellular demise, governed by a complex network of specific genes and proteins. The identification of multiple forms of programmed cell death has significantly advanced the understanding of its intricate mechanisms, as demonstrated in recent studies. A thorough grasp of these processes is essential across various biological disciplines and in the study of diseases. Nonetheless, despite notable progress, the exploration of the relationship between programmed cell death and disease, as well as its clinical application, are still in a nascent stage. Therefore, further exploration of programmed cell death and the development of corresponding therapeutic methods and strategies holds substantial potential. Our review provides a detailed examination of the primary mechanisms behind apoptosis, autophagy, necroptosis, pyroptosis, and ferroptosis. Following this, the discussion delves into biological functions and diseases associated dysregulated programmed cell death. Finally, we highlight existing and potential therapeutic targets and strategies focused on cancers and neurodegenerative diseases. This review aims to summarize the latest insights on programmed cell death from mechanisms to diseases and provides a more reliable approach for clinical transformation.

Abstract
PURPOSE While copper (Cu) is essential for biological organisms, excessive Cu can be harmful. Ferroptosis is a programmed cell death pathway, but the role of ferroptosis in renal injury induced by Cu is limited. The aim of this study was to investigate the role of ferroptosis in kidney injury in chickens and the molecular mechanism by which Cu promotes renal ferroptosis. MATERIALS AND METHODS Chicken were subjected to Cu treatment by artificially adding excess Cu to the basal diet (the Cu concentration in the diet was supplemented to 110-330 mg/kg), and the impact on kidney fibrosis, tissue structure, and ferroptosis-related molecular markers was studied. Then, the expression levels of genes and proteins related to ferroptosis, iron metabolism and ferroautophagy were detected to explore the promoting effect of Cu on ferroptosis in chicken kidney. MAIN FINDINGS Cu treatment resulted in significant fibrosis and tissue structure damage in chicken kidneys. Molecular analysis revealed a significant upregulation of LC3Ⅱ, P62, ATG5, and NCOA4, along with a decrease in FTH1 and FTL protein levels. Additionally, crucial markers of ferroptosis, including the loss of GPX4, SLC7A11, and FSP1, and an increase in PTGS2 and ACSL4 protein levels, were observed in chicken kidneys after Cu exposure. CONCLUSION Our study showed that dietary Cu excess caused kidney injury in brochickens and exhibited ferroptosis-related features, including lipid peroxidation, reduction of ferritin, and downregulation of FSP1 and GPX4. These results indicate that excess Cu can induce renal ferroptosis and lead to kidney injury in chickens. This study highlights the complex interplay between Cu ions and ferroptosis in the context of renal injury and provides a new perspective for understanding the mechanism of Cu-induced renal injury.

Abstract
Synaptic efficacy is critical for memory formation and consolidation. Accumulating evidence suggest that synapses are impaired during Wilson's disease (WD), contributing to neuronal dysfunction and cognitive decline. WD is a prototypical condition among the copper metabolism disorders. Cognitive impairment is a common feature of affected patients with neurological symptoms, presenting as memory deficits, decreased cognitive flexibility, and impaired learning capabilities. These cognitive deficits can significantly impact the quality of life, affecting work and academic performance. However, the mechanisms mediating the inhibitory synaptic dysfunction in WD are incompletely understood. We investigated the effects of the double-stranded RNA-dependent protein kinase/eukaryotic initiation factor 2α (PKR/eIF2α) pathway on synaptic structure and function in WD using a murine model, toxic milk (TX mice). During mouse open-field tests, we noted a substantial rise in the mobility/immobility ratio among WD model animals compared to that in WT mice. Additionally, WD mice exhibited diminished central area exploration, as evidenced by reduced travel distance. Moreover, they displayed prolonged escape latency in the Barnes maze, suggesting that chronic copper accumulation is associated with neuropsychiatric alterations and cognitive impairment. We also found a decrease in the expression of synapse-associated proteins (synapsin 1, synaptophysin, postsynaptic density protein-93 [PSD93], postsynaptic density protein-95 [PSD95]), and vesicle-associated membrane protein2 [VAMP2]) besides abnormal neurotransmitter levels (including glutamate and GABA), indicating the presence of synaptic dysfunction in TX mice. Inhibiting PKR via C16 prevented these changes, suggesting that dysfunctional cognition is associated with the PKR/eIF2α pathway. We also observed changes in synapses, vesicles, dendritic spine density, and dendritic length that were associated with the presence of cognitive dysfunction. Further investigation revealed that C16 treatment decreased the TUNEL-positive cell numbers in the hippocampus of TX mice and prevented 8-OHdG-induced synaptic dysfunction. Results suggest that PKR downregulation prevents copper-induced synaptic dysfunction in the murine WD model. Therefore, targeting PKR pharmacologically may be a potential therapeutic strategy for treating the copper-induced neuropathology of patients with WD.

While such increase per se may be beneficial for the growth of some crops, it comes with a caveat of affecting crop nutritional status. Here, we present a comprehensive analysis of changes in concentration of essential (Cu, Fe, Mn, Zn, Mo, Ni) and non-essential (Ba, Cd, Cr, Hg, Pb, and Sr) heavy metals in response to elevated CO2, drawing on a meta-analysis of 1216 paired observations. The major findings are as follows: (1) Elevated CO2 leads to reduced concentrations of Cu, Fe, Mn, and Zn in crops; (2) the extent of above reduction varies among plants species and is most pronounced in cereals and then in legumes and vegetables; (3) reduction in accumulation of non-essential (toxic) metals is less pronounced, potentially leading to an unfavorable essential/non-essential metal ratio in plants; (4) the above effects will come with significant implication to human health, exacerbating effects of the "hidden hunger" caused by the lack of Fe and Zn in the human diets. The paper also analyses the mechanistic basis of nutrient acquisition (both at physiological and molecular levels) and calls for the changes in the governmental policies to increase efforts of plant breeders to create genotypes with improved nutrient use efficiency for essential micronutrients while uncoupling their transport from non-essential (toxic) heavy metals.

Elabela alleviates cuproptosis and vascular calcification in vitaminD3- overloaded mice via regulation of the PPAR-γ /FDX1 signaling. Mol Med 2024; 30:223. [PMID: 39567863 PMCID: PMC11577739 DOI: 10.1186/s10020-024-00997-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2024] [Accepted: 11/12/2024] [Indexed: 11/22/2024] Open
Abstract
BACKGROUND Vascular calcification is a crucial pathophysiological process associated with age-related cardiovascular diseases. Elabela, a recently identified peptide, has emerged as a significant player in the regulation of cardiovascular function and homeostasis. However, the effects and underlying mechanisms of Elabela on age-related vascular calcification remain largely unexplored. METHODS In-vivo vascular calcifications of C57BL/6J mice (8-week-old) and young (8-week-old) or aged (72-week-old) SD rats were injected with vitamin D3 (VitD3) or saline, respectively. Furthermore, the VitD3-overloaded mice received Elabela (1 mg/kg/d), peroxisome proliferators-activated receptor-γ (PPAR-γ) activator Rosiglitazone (5 mg/kg/d) or copper-ionophore Elesclomol (20 mg/kg/d), respectively. As for in-vitro studies, primary rat vascular smooth muscle cells (VSMCs) were isolated from aortas and cultured for explore the role and underlying mechanism of Elabela in vascular calcification. RESULTS There were marked increases in FDX1 and Slc31a1 levels in both aortas and VSMCs during vascular calcification, coinciding with a rise in copper levels and a decrease in Elabela levels. Alizarin red and von-Kossa staining indicated that the administration of Elabela effectively hindered the progression of vascular cuproptosis and arterial calcification in VitD3-overloaded mice and rat arterial rings models. Moreover, Elabela significantly suppressed osteogenic differentiation and calcium deposition in VSMCs and strikingly reversed high phosphate-induced augmentation of FDX1 expression, DLAT aggregation as well as intracellular copper ion levels. More importantly, Elabela exhibited remarkable abilities to prevent mitochondrial dysfunctions in primary rat VSMCs by maintaining mitochondrial membrane potential, inhibiting mitochondrial division, reducing mitochondrial ROS production and increasing ATP levels. Interestingly, Elabela mitigated cellular senescence and production of pro-inflammatory cytokines including IL-1α, IL-1β, IL-6, IL-18 and TNF-α, respectively. Furthermore, Elabela upregulated the protein levels of PPAR-γ in VitD3-overloaded mice. Administrating PPAR-γ inhibitor GW9662 or blocking the efflux of intracellular copper abolished the protective effect of Elabela on vascular calcification by enhancing levels of FDX1, Slc31a1, Runx2, and BMP2. CONCLUSION Elabela plays a crucial role in protecting against vascular cuproptosis and arterial calcification by activating the PPAR-γ /FDX1 signaling. Elabela supplementation and cuproptosis suppression serve as effective therapeutic approaches for managing vascular calcification and related cardiovascular disorders.

Abstract
OBJECTIVES This study aimed to evaluate whether oral zinc or copper supplementation affected the efficacy and sustainability of botulinum toxin-A (BTX-A) injection in masseter muscle of albino rats. MATERIALS AND METHODS 32 adult male albino rats were allocated equally into four groups: group I (control), group II received 10U BTX-A injection, group III received 10U BTX-A injection + zinc (1 mg, 4 days pre-injection), and group IV received 10U BTX-A injection + copper (0.04 mg, 7 days post-injection). Rats were euthanized at 2 and 12 weeks (4 rats per subgroup) after injection. The masseter muscle was examined via histological, histochemical, histomorphometrical and real-time polymerase chain reaction (qRT-PCR) analyses. RESULTS The histopathological results of the BTX-A group showed atrophied muscle fibers with increased atrophy with time compared to the control group. The BTX-A + zinc group displayed more atrophy compared to BTX-A group. Conversely, the BTX-A + copper group demonstrated improved histology of muscle fibers compared to BTX-A and BTX-A + zinc groups. Histomorphometric analysis of Masson trichrome staining at 2 and 12 weeks revealed that collagen area percentage was the highest in the BTX-A + copper and control groups, followed by BTX-A and BTX-A + zinc groups. At 12 weeks, the nuclear factor kappa beta (NF-κB) mRNA expression was significantly higher in BTX-A + zinc and BTX-A groups compared to BTX-A + copper group and relative to the control group. CONCLUSION Zinc supplementation significantly improved the effectiveness and durability of BTX-A, whereas copper supplementation reduced its efficacy.

Abstract
The initial stages of acute pancreatitis (AP) are characterized by a significant event - acinar ductal metaplasia (ADM). This process is a crucial feature of both acute and chronic pancreatitis, serving as the first step in the development of pancreatic cancer. Ion channels are integral transmembrane proteins that play a pivotal role in numerous biological processes by modulating ion flux. In many diseases, the expression and activity of ion channels are often dysregulated. Metal ions, including calcium ions (Ca2+), ferrous ions (Fe2+), and Copper ions (Cu2+), assume a distinctive role in cellular metabolism. These ions possess specific biological properties relevant to cellular function. However, the interactions among these ions exacerbate the imbalance within the intracellular environment, resulting in cellular damage and influencing the progression of AP. A more in-depth investigation into the mechanisms by which these ions interact with acinar cells is essential for elucidating AP's pathogenesis and identifying novel therapeutic strategies. Currently, treatment for AP primarily focuses on pain relief, complications prevention, and prognosis improvement. There are limited specific treatments targeting acinous cell dedifferentiation or ion imbalance. This study aims to investigate potential therapeutic strategies by examining ion crosstalk within acinar cells in the context of acute pancreatitis.

Impacts of Nano-Composite of Copper and Carbon on Intestinal Luminal Micro-Ecosystem and Mucosal Homeostasis of Yellow-Feather Broilers. Microorganisms 2024; 12:2247. [PMID: 39597636 PMCID: PMC11596944 DOI: 10.3390/microorganisms12112247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2024] [Revised: 11/01/2024] [Accepted: 11/04/2024] [Indexed: 11/29/2024] Open
Abstract
The present study was undertaken to evaluate the impacts of nano-composites of copper and carbon (NCCC) on the intestinal luminal micro-ecosystem and mucosal homeostasis of yellow-feather broilers. A total of two-hundred and forty 1-day-old male yellow-feather broilers were randomly allocated into four groups, each with five replications of twelve birds. The control (CON) group received a corn-soybean basal diet, while the N50, N100, and N200 groups were supplemented with 50, 100, and 200 mg/kg of NCCC in basal diets, respectively. The trial duration was 63 days. The findings demonstrated that there were slight impacts of NCCC addition on the intestinal luminal micro-ecosystem of broilers, with the fecal moisture content in the N100 group being slightly higher on Day 3 in the starter phase (p < 0.05). The cecal microbiota structure also did not obviously change (p > 0.05), in spite of the fall in the relative abundance of the Ruminococcus torques group in the N50 group and norank Clostridia UCG-014 in N200 group (p < 0.05). But for intestinal mucosal homeostasis, NCCC played a crucial part in jejunal morphology, tight junction, immunologic status, and antioxidant capacity. There was linear growth in villus height and a quadratic increase in villus height, crypt depth and their ratio with the increase in NCCC dosage (p < 0.05), and 100 mg/kg NCCC supplementation could intensify the expression of CLDN-3 genes (p < 0.05). In addition, IL-4 and IL-10 linearly increased after NCCC treatment (p < 0.05), along with some irregular changes in sIgA (p < 0.05). In addition, higher jejunal mucosal total antioxidant capacities in N50 and N200 groups were also observed (p < 0.05). Overall, NCCC treatment optimized the intestinal mucosa function of broilers in terms of physical barrier and immune and antioxidant capacities, but exerted subtle influence in the luminal environment of yellow-feather broilers. More precisely, dietary supplementation with 50 mg/kg NCCC is recommended for intestinal homeostasis of broilers.

Abstract
In poultry diets, copper is an essential nutrient that is critical for various physiological functions. Although copper sulfate is commonly used due to its cost-effectiveness, organic copper sources are gaining popularity because of their superior production outcomes and environmental benefits. Nevertheless, understanding the distinct bioaccessibility of inorganic and organic copper in diverse dietary setting remains limited. This study investigated the bioaccessibility of copper sulfate, copper amino acid chelate, and copper proteinate in the intestine via in vitro digestion and in situ dialysis. The results showed significant differences in the molecular size distribution of compounds formed by different copper salts within the intestinal environment, thereby leading to varying bioaccessibility. Copper sulfate has a bioaccessibility of 47 % ± 4%, which is significantly lower than copper amino acid chelate and copper proteinate (63% ± 5%, and 60% ± 4%, respectively) in purified diet systems. Similarly, in whey protein systems, sulfate records 54% ± 10% bioaccessibility compared to 78% ± 9% and 76% ± 5% for copper amino acid chelate and copper proteinate. Coexisting feed ingredients have a significant impact on copper bioaccessibility. Copper sulfate forms precipitates, reducing its bioaccessibility to 34% ± 1% in sodium nitrate solution. The addition of digestive enzyme increases the bioaccessibility of copper sulfate to 81% ± 2% by providing organic ligands. Digestive enzyme also enhanced the bioaccessibility of copper proteinate from 36% ± 4% to 81% ± 4% by degrading its ligands. However, feed ingredients may decrease copper bioaccessibility by forming macromolecular complexes with copper, as all the organic ligands can competitively bind with copper in the intestine. These findings emphasize the importance of considering copper salt types and diet composition in animal nutrition practices.

Abstract
Adenosine-5'-triphosphate (ATP) is a critical biological molecule that functions as the primary energy currency within cells. ATP synthesis occurs in the mitochondria, and variations in its concentration can significantly influence mitochondrial and cellular performance. Prior studies have established a link between ATP levels and a variety of diseases, such as cancer, neurodegenerative conditions, ischemia, and hypoglycemia. Consequently, researchers have developed many fluorescent probes for ATP detection, recognizing the importance of monitoring intracellular ATP levels to understand cellular processes. These probes have been effectively utilized for visualizing ATP in living cells and biological samples. In this comprehensive review, we categorize fluorescent sensors developed in the last five years for ATP detection. We base our classification on fluorophores, structure, multi-response channels, and application. We also evaluate the challenges and potential for advancing new generations of fluorescence imaging probes for monitoring ATP in living cells. We hope this summary motivates researchers to design innovative and effective probes tailored to ATP sensing. We foresee imminent progress in the development of highly sophisticated ATP probes.

Abstract
Breast cancer is the most common and lethal malignancy among women worldwide. Cuproptosis, a newly identified copper-dependent cell death, is closely associated with cancer development. However, its regulatory mechanisms in breast cancer are not well studied. This study aims to establish a prognostic model for breast cancer to improve risk stratification. The mRNA expression data was downloaded from The Cancer Genome Atlas and Gene Expression Omnibus databases. Consensus clustering identified patterns based on cuproptosis-related genes. Key genes were screened using Weighted Gene Co-Expression Network Analysis and differentially expressed gene analysis. A prognostic model was constructed using Cox regression and evaluated with time-dependent receiver operating characteristic and Kaplan-Meier analyses. Functional pathways, immune cell infiltration, and other tumor characteristics were also analyzed. Two distinct cuproptosis patterns were identified. The top 21 differentially expressed genes, significantly associated with survival, were used to construct the prognostic model. The risk score has a negative correlation with survival. Enrichment analysis showed immune-related pathways enriched in the low-risk group, which also had more immune cell infiltration, higher stromal component, lower tumor purity, and lower tumor heterogeneity. Finally, significant differences of half maximal inhibitory concentration were also observed between patients in high- and low-risk groups who received chemotherapy and targeted therapy drugs. These findings in our study may provide evidence for further research and individualized management of breast cancer.

Abstract
Colorectal cancer (CRC) is a growing public health problem. Several clinical studies have shown a potentially oncogenic role of copper in CRC progression, but the reports are inconsistent. To examine published evidence on the association between tissue copper status and CRC, we carried out a systematic review and meta-analysis, searching Cochrane Library, EBSCOhost, Embase, ProQuest, PubMed/Medline, Scopus, and Web of Science for studies reporting colon tumor and matched non-cancerous tissue copper concentrations in CRC patients for articles published till June 2023. Based on a random effects model, standardized mean differences (SMD) were assessed. We also completed a replication study on 17 CRC patients that analyzed copper levels in both cancer tissue specimens and healthy mucosa dissected from the same patient. Thirteen studies investigating copper levels (including the replication study) in colorectal specimens from a pooled total of 312 CRC and 298 healthy mucosa were selected. Our meta-analysis estimated a high between-study heterogeneity (I2 = 96%) and lower levels of copper in CRC tissue cancer specimens than in matched healthy mucosa: the decrease was equal to - 0.74 (95% CI, - 2.18; 0.71) but was not significant. The replication study showed a significant decrease in tissue cancer specimens. Sensitivity analyses of the meta-analysis revealed that pre-analytical methodology for tissue preparation significantly reduced the between-study heterogeneity strongly influencing copper levels (p < 0.01), indicating a copper decrease in the cytoplasmic copper pool of the tumor tissue suggesting a rapid turnover of the metal in cancer cells.

[PMID: 39430913 PMCID: PMC11486892 DOI: 10.34133/bmr.0094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2024] [Revised: 09/09/2024] [Accepted: 09/24/2024] [Indexed: 10/22/2024] Open
Abstract
The recent discovery of cuproptosis, a novel copper-ion-induced cell death pathway, has suggested the novel therapeutic potential for treating heterogeneous and drug-resistant cancers. Currently, copper ionophore-based therapeutics have been designed to treat cancers, utilizing copper ions as a strategic tool to impede tumor proliferation and promote cellular demise. However, limitations of copper ionophore-based therapies include nontargeted delivery of copper ions, low tumor accumulation, and short half-life. Strategies to enhance specificity involve targeting intracellular cuproptosis mechanisms using nanotechnology-based drugs. Additionally, the importance of exploring combination therapies cannot be overstated, as they are a key strategy in improving the efficacy of cancer treatments. Recent studies have reported the anticancer effects of nanomedicines that can induce cuproptosis of cancer both in vitro and in vivo. These cuproptosis-targeted nanomedicines could improve delivery efficiency with the pharmacokinetic properties of copper ion, resulting in increasing cuproptosis-based anticancer effects. This review will summarize the intricate nexus between copper ion and carcinogenesis, examining the pivotal roles of copper homeostasis and its dysregulation in cancer progression and fatality. Furthermore, we will introduce the latest advances in cuproptosis-targeted nanomedicines for cancer treatment. Finally, the challenges in cuproptosis-based nanomedicines will be discussed for future development directions.

Abstract
Iron, an essential mineral in the body, is involved in numerous physiological processes, making the maintenance of iron homeostasis crucial for overall health. Both iron overload and deficiency can cause various disorders and human diseases. Ferroptosis, a form of cell death dependent on iron, is characterized by the extensive peroxidation of lipids. Unlike other kinds of classical unprogrammed cell death, ferroptosis is primarily linked to disruptions in iron metabolism, lipid peroxidation, and antioxidant system imbalance. Ferroptosis is regulated through transcription, translation, and post-translational modifications, which affect cellular sensitivity to ferroptosis. Over the past decade or so, numerous diseases have been linked to ferroptosis as part of their etiology, including cancers, metabolic disorders, autoimmune diseases, central nervous system diseases, cardiovascular diseases, and musculoskeletal diseases. Ferroptosis-related proteins have become attractive targets for many major human diseases that are currently incurable, and some ferroptosis regulators have shown therapeutic effects in clinical trials although further validation of their clinical potential is needed. Therefore, in-depth analysis of ferroptosis and its potential molecular mechanisms in human diseases may offer additional strategies for clinical prevention and treatment. In this review, we discuss the physiological significance of iron homeostasis in the body, the potential contribution of ferroptosis to the etiology and development of human diseases, along with the evidence supporting targeting ferroptosis as a therapeutic approach. Importantly, we evaluate recent potential therapeutic targets and promising interventions, providing guidance for future targeted treatment therapies against human diseases.

Evolutionary Conserved and Divergent Responses to Copper Zinc Superoxide Dismutase Inhibition in Plants. PLANT, CELL & ENVIRONMENT 2024. [PMID: 39400938 DOI: 10.1111/pce.15198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 09/24/2024] [Accepted: 09/25/2024] [Indexed: 10/15/2024]
Abstract
After an initial evolution in a reducing environment, life got successively challenged by reactive oxygen species (ROS), especially during the great oxidation event (GOE) that followed the development of photosynthesis. Therefore, ROS are deeply intertwined into the physiological, morphological and transcriptional responses of most present-day organisms. Copper-zinc superoxide dismutases (CuZnSODs) evolved during the GOE and are present in charophytes and extant land plants, but nearly absent from chlorophytes. The chemical inhibitor of CuZnSOD, lung cancer screen 1 (LCS-1), could greatly facilitate the study of SODs in diverse plants. Here, we determined the impact of chemical inhibition of plant CuZnSOD activity, on plant growth, transcription and metabolism. We followed a comparative approach by using different plant species, including Marchantia Polymorpha and Physcomitrium patens, representing bryophytes, the sister lineage to vascular plants, and Arabidopsis thaliana. We show that LCS-1 causes oxidative stress in plants and that the inhibition of CuZnSODs provoked a similar core response that mainly impacted glutathione homoeostasis in all plant species analysed. That said, Physcomitrium and Arabidopsis, which contain multiple CuZnSOD isoforms showed a more complex and exacerbated response. In addition, an untargeted metabolomics approach revealed a specific metabolic signature for each plant species. Our comparative analysis exposes a conserved core response at the physiological and transcriptional level towards LCS-1, while the metabolic response largely varies. These differences correlate with the number and localization of the CuZnSOD isoforms present in each species.
