Abstract
Ferroptosis is a novel, iron-dependent form of non-apoptotic cell death characterized by the accumulation of lipid reactive oxygen species (ROS) and mitochondrial shrinkage. It is closely associated with the onset and progression of various diseases, especially cancer, at all stages, making it a key focus of research for developing therapeutic strategies. Numerous studies have explored the role of microRNAs (miRNAs) in regulating ferroptosis by modulating the expression of critical genes involved in iron metabolism and lipid peroxidation. Due to their diversity, unique properties, and dynamic expression patterns in diseases, exosomal miRNAs are emerging as promising biomarkers. Exosomes act as biological messengers, delivering miRNAs to target cells through specific internalization, thus influencing the ferroptosis response in recipient cells. This review summarizes the roles of miRNAs, with particular focus on exosomal miRNAs, in ferroptosis and their implications for cancer pathology. By examining the molecular mechanisms of miRNAs, we aim to provide valuable insights into potential therapeutic approaches.

Abstract
Mesenchymal stem cell (MSC) therapy, with its unique properties, has garnered interest in cancer treatment. Exosomes (EXOs)-derived from MSC retain the paracrine components of MSCs and demonstrate increased stability, minimal immunogenicity, and low risk of unintended tumorigenesis. Enhanced endocytosis methods make them versatile delivery vehicles for therapeutic cargo. MSC-EXOs can either promote or inhibit carcinogenesis, mediated by paracrine factors and various RNA molecules, particularly microRNAs (miRNAs). The prospect of using MSC-EXOs as a delivery tool for antitumor miRNAs in solid tumor therapy is promising. Exosomes' intrinsic tumor-targeting abilities and low immunogenicity make them ideal for delivering miRNAs, which have shown potential as cancer therapeutics. miRNAs within MSC-EXOs molecules can stimulate tumor growth or induce non-apoptotic cell death pathways, such as ferroptosis, depending on context. Ferroptosis is a kind of controlled cell death that is associated with the pathophysiology of several illnesses and includes iron metabolism. There is growing evidence that miRNAs carried by exosomes derived from MSCs may control ferroptosis in tumor cells by altering key genes related to antioxidant defense, lipid peroxidation, and iron metabolism. Understanding their complex mechanisms in the tumor microenvironment and optimizing their cargo are critical steps toward harnessing their full therapeutic potential. This review provides a comprehensive overview of MSC-EXOs and their role in cancer treatment. We also discuss the potential of MSC-EXOs as delivery vehicles for miRNAs to enhance therapeutic efficacy, as well as the role of exosomal miRNAs in the induction of ferroptosis.

Abstract
Mesenchymal stem cell (MSC) therapy shows great potential for treating tissue impairments and immune disorders. Epigenetic regulation is a core molecular signature that ensures long-lasting memory in MSC functional modulation and mediates therapeutic efficacy. Studies reveal that transplanted MSCs drive epigenetic changes in recipient cells, which contributes to restoration of organismal and microenvironmental homeostasis. Extracellular vesicles (EVs) derived from MSCs, including exosomes and apoptotic vesicles (apoVs), enable the transfer of epigenetic regulators, orchestrating intercellular epigenetic reprogramming and signaling modulation in both local and systemic microenvironments. Here, the epigenetic regulation of MSC and EV therapies is reviewed, together with current challenges, aiming to deepen the understanding of donor-recipient communication and inspire next-generation approaches to counteract tissue defects and diseases.

BMC Cardiovasc Disord 2025; 25:215. [PMID: 40133811 PMCID: PMC11934478 DOI: 10.1186/s12872-025-04663-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2024] [Accepted: 03/13/2025] [Indexed: 03/27/2025] Open
Abstract
BACKGROUND Ischemic stroke (IS) is a common cardiovascular disease (CVD). Insulin-like growth factor 2 (IGF2), circZNF609, and circPUM1 are involved in metabolic regulation, vascular health, neuroprotection, and inflammation modulation and are relevant to IS mechanisms. This study investigated the effects of plasma exosomal expression of circZNF609, circPUM1, and IGF2 on IS. METHODS The expression of circZNF609, circPUM1, and IGF2 mRNA in exosomes was detected in 145 patients with IS and 290 controls using real-time qPCR in a cross-sectional study. Q1-Q4 represents the quartile groups based on the target gene expression levels. RESULTS There was no significant difference in the expression levels of circZNF609 and circPUM1 in the plasma exosomes between the IS and control groups (P > 0.05). However, a nonlinear relationship between the expression levels of circZNF609 in the IS group (P < 0.05). Exosomal IGF2 mRNA expression in the IS group was significantly lower than that in the control group (P = 0.043). The multifactorial adjusted results showed that in the case-control study of IS, circZNF609 in plasma exosomes was associated with a reduced risk of disease in group Q2 (adjusted OR: 0.565; P = 0.035) compared to that in group Q1, the low-expression group. In plasma exosomes, circZNF609 expression in group Q4 was associated with a reduced risk of disease in group Q1 (adjusted OR: 0.654; P = 0.004) compared to that in group Q1 (low expression). Plasma exosomes with IGF2 showed a reduced risk in the Q4 group with high IGF2 expression compared to that in the Q1 group with low IGF2 expression (adjusted OR: 0.543; P = 0.042). CONCLUSIONS This study suggests that the low expression of circZNF609, circPUM1, and IGF2 in peripheral blood plasma exosomes could pose a potential risk for IS and serve as biomarkers for clinical treatment.

Exosomal miR-499a-5p from human umbilical cord mesenchymal stem cells attenuates liver fibrosis via targeting ETS1/GPX4-mediated ferroptosis in hepatic stellate cells. J Nanobiotechnology 2025; 23:222.

Abstract
Liver fibrosis is a leading cause of liver-related mortality worldwide, yet effective therapies remain limited. Mesenchymal stem cells (MSCs) have recently shown promise in treating liver fibrosis due to their anti-inflammatory and anti-fibrotic properties. However, the precise molecular mechanisms by which MSCs exert their effects remain unclear. In this study, we explored how human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) contribute to treating liver fibrosis, and revealed a crucial role of ferroptosis in modulating hepatic stellate cells (HSCs) activity. We found that MSCs primarily promote ferroptosis in HSCs in an exosome-dependent manner. Specifically, MSC-derived exosomes (MSC-Exos) deliver miR-499a-5p, which interacts with the transcription factor ETS1, leading to the suppression of GPX4, a key regulator of ferroptosis, thereby reducing the fibrogenic activity of HSCs. Overexpression of ETS1 in HSCs counteracted miR-499a-5p-induced ferroptosis, underscoring the pathway's potential as a target for therapeutic intervention. Furthermore, molecular docking simulations further identified optimal ETS1-GPX4 binding sites. This research uncovers a novel mechanism by which MSCs may treat liver fibrosis, providing insights that could guide the development of more effective therapies for this widespread condition.

Abstract
More and more articles have shown that non-coding RNAs (ncRNAs) play a significant role in the pathogenesis and prognosis of ischemic stroke. However, the bibliometric analysis in ncRNAs and ischemic stroke is still lacking. This study retrieved the Web of Science Core Collection for relevant articles from January 1, 2010 to April 6, 2023. Bibliometrix R, VOSviewer, and CiteSpace were used to perform the bibliometric analysis. A total of 1058 articles were eligible for this review. The number of publications showed a fluctuating upward trend. The total citations were 28,698 times, and the average number of citations per article was 27.12 times. Our findings indicated ncRNAs has been increasingly investigated for its critical role in apoptosis, autophagy, angiogenesis, inflammation, oxidative stress, and blood-brain barrier after ischemic stroke by regulating target mRNAs, extracellular secretion, target proteins, and others. The microRNAs, circular RNAs, and long ncRNAs may be hotspots, and ferroptosis, METTL3, and exosome might be frontier in this field. Besides, ncRNAs have a promising future as diagnostic and prognostic biomarkers, molecular drug targets, and other targeted therapies for ischemic stroke. However, it still faces many challenges to be successfully applied in the clinical practice.

Abstract
Acute ischemic stroke is a clinical emergency and a condition with high morbidity, mortality, and disability. Accurate predictive, diagnostic, and prognostic biomarkers and effective therapeutic targets for acute ischemic stroke remain undetermined. With innovations in high-throughput gene sequencing analysis, many aberrantly expressed non-coding RNAs (ncRNAs) in the brain and peripheral blood after acute ischemic stroke have been found in clinical samples and experimental models. Differentially expressed ncRNAs in the post-stroke brain were demonstrated to play vital roles in pathological processes, leading to neuroprotection or deterioration, thus ncRNAs can serve as therapeutic targets in acute ischemic stroke. Moreover, distinctly expressed ncRNAs in the peripheral blood can be used as biomarkers for acute ischemic stroke prediction, diagnosis, and prognosis. In particular, ncRNAs in peripheral immune cells were recently shown to be involved in the peripheral and brain immune response after acute ischemic stroke. In this review, we consolidate the latest progress of research into the roles of ncRNAs (microRNAs, long ncRNAs, and circular RNAs) in the pathological processes of acute ischemic stroke-induced brain damage, as well as the potential of these ncRNAs to act as biomarkers for acute ischemic stroke prediction, diagnosis, and prognosis. Findings from this review will provide novel ideas for the clinical application of ncRNAs in acute ischemic stroke.

Abstract
INTRODUCTION Ischemic stroke (IS), a major cause of mortality and disability worldwide, remains a significant healthcare challenge due to limited therapeutic options. Ferroptosis, a distinct iron-dependent form of regulated cell death characterized by lipid peroxidation and oxidative stress, has emerged as a crucial mechanism in IS pathophysiology. This review explores the role of ferroptosis in IS and its potential for driving innovative therapeutic strategies. AREA COVERED This review delves into the practical implications of ferroptosis in IS, focusing on molecular mechanisms like lipid peroxidation, iron accumulation, and their interplay with inflammation, reactive oxygen species (ROS), and the Nrf2-ARE antioxidant system. It highlights ferroptotic proteins, small-molecule inhibitors, and non-coding RNA modulators as emerging therapeutic targets to mitigate neuroinflammation and neuronal cell death. Studies from PubMed (1982-2024) were identified using MeSH terms such as 'Ferroptosis' and 'Ischemic Stroke,' and only rigorously screened articles were included. EXPERT OPINION Despite preclinical evidence supporting the neuroprotective effects of ferroptosis inhibitors, clinical translation faces hurdles such as suboptimal pharmacokinetics and safety concerns. Advances in drug delivery systems, bioinformatics, and AI-driven drug discovery may optimize ferroptosis-targeting strategies, develop biomarkers, and improve therapeutic outcomes for IS patients.

Abstract
AIMS Circular RNAs (circRNAs) are critical in the progression of ischemic acute kidney injury (AKI). Nevertheless, the specific functions and regulatory pathways of mmu_circ_0001388 and hsa_circ_0029470 remain elusive. METHODS Real-time quantitative polymerase chain reaction (RT-qPCR) was utilized to assess the expression patterns of mmu_circ_0001388, hsa_circ_0029470, and miR-139b-3p. Protein expressions of nuclear respiratory factor 1 (NRF1), transcription factor 4 (TCF4), glutathione peroxidase 4 (GPX4), and Acyl-CoA synthetase long-chain family member 4 (ACSL4) were identified via immunoblotting. Furthermore, the functions and control mechanisms of mmu_circ_003062 and hsa_circ_0075663 were examined via diverse cell and animal studies, encompassing bioinformatics prediction, dual-luciferase reporter (DLR), chromatin immunoprecipitation (ChIP), fluorescence in situ hybridization (FISH), flow cytometry (FCM), hematoxylin and eosin (H&E) staining, dihydroethidium (DHE), TUNEL, immunohistochemistry, and transmission electron microscopy (TEM), and Fe2+ assay. KEY FINDINGS Initially, the induction of mmu_circ_0001388 by NRF1 was observed in vitro and in vivo following ischemia/reperfusion (I/R) injury. Subsequently, knockdown or overexpression of mmu_circ_0001388 was found to either promote or inhibit ferroptosis caused by I/R in Boston University mouse proximal tubule (BUMPT) cells, respectively. From a mechanistic standpoint, mmu_circ_0001388 was found to function as a sponge for miR-193b-3p, which promoted TCF4 and subsequently enhanced GPX4, thereby suppressing ferroptosis. Finally, the overexpression of mmu_circ_0001388 was shown to ameliorate I/R-induced AKI in mice. In parallel, hsa_circ_0029470, homologous to mmu_circ_0001388, demonstrated an identical control pathway in human renal tubular epithelial (HK-2) cells. SIGNIFICANCE The NRF1/mmu_circ_0001388, hsa_circ_0029470/miR-193b-3p/TCF4/GPX4 axis is pivotal in regulating ferroptosis induced by ischemic AKI and holds potential as a therapeutic target.

Abstract
Cardiovascular diseases (CVDs) encompass a range of disorders affecting the heart and blood vessels, such as coronary heart disease, cerebrovascular disease (e.g., stroke), peripheral arterial disease, congenital heart anomalies, deep vein thrombosis, and pulmonary embolism. CVDs are often referred to as the leading cause of mortality worldwide. Recent advancements in deep sequencing have unveiled a plethora of noncoding RNA transcripts, including circular RNAs (circRNAs), which play pivotal roles in the regulation of CVDs. A decade of research has differentiated various circRNAs by their vasculoprotective or deleterious functions, revealing potential therapeutic targets. This review provides an overview of circRNAs and a comprehensive examination of CVDs, the regulatory circRNAs within the vasculature, and the burgeoning research domain dedicated to these noncoding RNAs.

Abstract
Ischemic stroke (IS) remains a leading cause of mortality and long-term disability worldwide, with limited therapeutic options available. Despite the success of early interventions, such as tissue-type plasminogen activator administration and mechanical thrombectomy, many patients continue to experience persistent neurological deficits. The pathophysiology of IS is multifaceted, encompassing excitotoxicity, oxidative and nitrosative stress, inflammation, and blood-brain barrier disruption, all of which contribute to neural cell death, further complicating the treatment of IS. Recently, extracellular vesicles (EVs) secreted naturally by various cell types have emerged as promising therapeutic agents because of their ability to facilitate selective cell-to-cell communication, neuroprotection, and tissue regeneration. Furthermore, engineered EVs, designed to enhance targeted delivery and therapeutic cargo, hold the potential to improve their therapeutic benefits by mitigating neuronal damage and promoting neurogenesis and angiogenesis. This review summarizes the characteristics of EVs, the molecular mechanisms underlying IS pathophysiology, and the emerging role of EVs in IS treatment at the molecular level. This review also explores the recent advancements in EV engineering, including the incorporation of specific proteins, RNAs, or pharmacological agents into EVs to enhance their therapeutic efficacy.

Abstract
Ischemic stroke is a devastating condition that occurs due to the interruption of blood flow to the brain, resulting in a range of cellular and molecular changes. In recent years, there has been growing interest in the role of ferroptosis, a newly identified form of regulated cell death, in ischemic stroke. Ferroptosis is driven by the accumulation of lipid peroxides and is characterized by the loss of membrane integrity. Additionally, oxidative stress, which refers to an imbalance between prooxidants and antioxidants, is a hallmark of ischemic stroke and significantly contributes to the pathogenesis of the disease. In this review, we explore the interactions between ferroptosis and oxidative stress in ischemic stroke. We examine the underlying mechanisms through which oxidative stress induces ferroptosis and how ferroptosis, in turn, exacerbates oxidative stress. Furthermore, we discuss potential therapeutic strategies that target both ferroptosis and oxidative stress in the treatment of ischemic stroke. Overall, this review highlights the complex interplay between ferroptosis and oxidative stress in ischemic stroke and underscores the need for further research to identify novel therapeutic targets for this condition.

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.

Abstract
Stroke is the number one cause of morbidity in the United States and number two cause of death worldwide. There is a critical unmet medical need for more effective treatments of ischemic stroke, and this need is increasing with the shift in demographics to an older population. Recently, several studies have reported the therapeutic potential of stem cell-derived exosomes as new candidates for cell-free treatment in stoke. This review focuses on the use of stem cell-derived exosomes as a potential treatment tool for stroke patients. Therapy using exosomes can have a clear clinical advantage over stem cell transplantation in terms of safety, cost, and convenience, as well as reducing bench-to-bed latency due to fewer regulatory milestones. In this review article, we focus on (1) the therapeutic potential of exosomes in stroke treatment, (2) the optimization process of upstream and downstream production, and (3) preclinical application in a stroke animal model. Finally, we discuss the limitations and challenges faced by exosome therapy in future clinical applications.

Abstract
Cell death encompasses various mechanisms, including necrosis and apoptosis. Ferroptosis, a unique form of regulated cell death, emerged as a non-apoptotic process reliant on iron and reactive oxygen species (ROS). Distinguishing itself from other forms of cell death, ferroptosis exhibits distinct morphological, biochemical, and genetic features. Circular RNAs (circRNAs), a novel class of RNA molecules, play crucial regulatory roles in ferroptosis-mediated pathways and cellular processes. With their circular structure and stability, circRNAs function as microRNA sponges and participate in protein regulation, offering diverse mechanisms for cellular control. Accumulating evidence indicates that circRNAs are key players in diseases associated with ferroptosis, presenting opportunities for diagnostic and therapeutic applications. This study explores the regulatory roles of circRNAs in ferroptosis and their potential in diseases such as cancer, neurological disorders, and cardiovascular diseases. By investigating the relationship between circRNAs and ferroptosis, this research provides new insights into the diagnosis, treatment, and prognosis of ferroptosis-related diseases. Furthermore, the therapeutic implications of targeting circRNAs in cancer treatment and the modulation of ferroptosis pathways demonstrate the potential of circRNAs as diagnostic markers and therapeutic targets. Overall, understanding the involvement of circRNAs in regulating ferroptosis opens up new avenues for advancements in disease management.

Abstract
Stem cells represent an attractive resource for cardiac regeneration. However, the survival and function of transplanted stem cells is poor and remains a major challenge for the development of effective therapies. As two main cell types currently under investigation in heart repair, mesenchymal stromal cells (MSCs) indirectly support endogenous regenerative capacities after transplantation, while induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) functionally integrate into the damaged myocardium and directly contribute to the restoration of its pump function. These two cell types are exposed to a common microenvironment with many stressors in ischemic heart tissue. This review summarizes the research progress on the mechanisms and challenges of MSCs and iPSC-CMs in post-MI heart repair, introduces several randomized clinical trials with 3D-mapping-guided cell therapy, and outlines recent findings related to the factors that affect the survival and function of stem cells. We also discuss the future directions for optimization such as biomaterial utilization, cell combinations, and intravenous injection of engineered nucleus-free MSCs.

Abstract
Human antigen R (HuR) is a universally expressed RNA-binding protein that plays an essential role in governing the fate of mRNA transcripts. Accumulating evidence indicated that HuR is involved in the development and functions of several cell types. However, its role in cerebral ischemia/reperfusion injury (CIRI) remains unclear. In this study, we found that HuR was significantly upregulated after CIRI. Moreover, we found that silencing HuR could inhibit the inflammatory response of microglia and reduce the damage to neurons caused by oxygen-glucose deprivation/reperfusion treatment. In vivo, we found that microglial HuR deficiency significantly ameliorated CIRI and reduced NLRP3-mediated inflammasome activation. Mechanistically, we found that HuR could regulate NLRP3 mRNA stability by binding to the AU-rich element (ARE) region within the 3' untranslated region (UTR) of NLRP3 mRNA. In addition, we found that the upregulation of HuR was dependent on the upregulation of NADPH oxidase-mediated ROS accumulation. Collectively, our studies revealed that HuR could regulate NLRP3 expression and that HuR deficiency abrogated the enhanced NLRP3 signaling in experimental ischemic stroke. Targeting HuR may be a novel therapeutic strategy for cerebral ischemic stroke treatment.

Abstract
Background Breast cancer (BC) poses a serious threat to human health. Disulfidptosis is a recently discovered form of cell death associated with cancer prognosis and progression. However, the relationship between BC and disulfidptosis remains unclear. Methods We integrated single-cell sequencing and transcriptome sequencing in BC to assess the abundance and mutation status of disulfidptosis-associated genes (DAGs). Subsequently, we clustered the samples based on DAGs and constructed a prognostic model associated with disulfidptosis. Additionally, we performed pathway enrichment, immune response, and drug sensitivity analyses on the model. Finally, we validated the prognostic genes through Immunohistochemistry (IHC). Results The single-cell analysis identified 21 cell clusters and 8 cell types. By evaluating the abundance of DAGs in different cell types, we found specific expression of the disulfidoptosis core gene SLC7A11 in mesenchymal stem cells (MSCs). Through unsupervised clustering of DAGs, we identified two clusters. Utilizing differentially expressed genes from these clusters, we selected 7 genes (AFF4, SLC7A11, IGKC, IL6ST, LIMD2, MAT2B, and SCAND1) through Cox and Lasso regression to construct a prognostic model. External validation demonstrated good prognostic prediction of our model. BC patients were stratified into two groups based on riskscore, with the high-risk group corresponding to a worse prognosis. Immune response analysis revealed higher TMB and lower TIDE scores in the high-risk group, while the low-risk group exhibited higher CTLA4/PD-1 expression. This suggests that both groups may respond to immunotherapy, necessitating further research to elucidate potential mechanisms. Drug sensitivity analysis indicated that dasatinib, docetaxel, lapatinib, methotrexate, paclitaxel, and sunitinib may have better efficacy in the low-risk group. Finally, Immunohistochemistry (IHC) validated the expression of prognostic genes, demonstrating higher levels in tumor tissue compared to normal tissue. Conclusion Our study has developed an effective disulfidptosis-related prognostic prediction tool for BC and provides personalized guidance for the clinical management and immunotherapy selection of BC patients.

Abstract
Exosome-based treatments are gaining traction as a viable approach to addressing the various issues faced by an ischemic stroke. These extracellular vesicles, mainly produced by Mesenchymal Stem Cells (MSCs), exhibit many properties with substantial therapeutic potential. Exosomes are particularly appealing for stroke therapy because of their low immunogenicity, effective cargo transport, and ability to cross the blood-brain barrier. Their diverse effects include neuroprotection, angiogenesis stimulation, inflammatory response modulation, and cell death pathway attenuation, synergistically promoting neuronal survival, tissue regeneration, and functional recovery. Exosomes also show potential as diagnostic indicators for early stroke identification and customized treatment options. Despite these promising qualities, current exosome-based therapeutics have some limitations. The heterogeneity of exosome release among cell types, difficulty in standardization and isolation techniques, and complications linked to dosage and targeted administration necessitates extensive investigation. It is critical to thoroughly understand exosomal processes and their complicated interactions within the cellular milieu. To improve the practicality and efficacy of exosome-based medicines, research efforts must focus on improving production processes, developing robust evaluation criteria, and developing large-scale isolation techniques. Altogether, exosomes' multifunctional properties offer a new route for transforming stroke treatment and significantly improving patient outcomes.
