Fibrotic scar formation after cerebral ischemic stroke: Targeting the Sonic hedgehog signaling pathway for scar reduction. Neural Regen Res 2026; 21:756-768.

JOURNAL/nrgr/04.03/01300535-202602000-00044/figure1/v/2025-05-05T160104Z/r/image-tiff Recent studies have shown that fibrotic scar formation following cerebral ischemic injury has varying effects depending on the microenvironment. However, little is known about how fibrosis is induced and regulated after cerebral ischemic injury. Sonic hedgehog signaling participates in fibrosis in the heart, liver, lung, and kidney. Whether Shh signaling modulates fibrotic scar formation after cerebral ischemic stroke and the underlying mechanisms are unclear. In this study, we found that Sonic Hedgehog expression was upregulated in patients with acute ischemic stroke and in a middle cerebral artery occlusion/reperfusion injury rat model. Both Sonic hedgehog and Mitofusin 2 showed increased expression in the middle cerebral artery occlusion rat model and in vitro fibrosis cell model induced by transforming growth factor-beta 1. Activation of the Sonic hedgehog signaling pathway enhanced the expression of phosphorylated Smad 3 and Mitofusin 2 proteins, promoted the formation of fibrotic scars, protected synapses or promoted synaptogenesis, alleviated neurological deficits following middle cerebral artery occlusion/reperfusion injury, reduced cell apoptosis, facilitated the transformation of meninges fibroblasts into myofibroblasts, and enhanced the proliferation and migration of meninges fibroblasts. The Smad3 phosphorylation inhibitor SIS3 reversed the effects induced by Sonic hedgehog signaling pathway activation. Bioinformatics analysis revealed significant correlations between Sonic hedgehog and Smad3, between Sonic hedgehog and Mitofusin 2, and between Smad3 and Mitofusin 2. These findings suggest that Sonic hedgehog signaling may influence Mitofusin 2 expression by regulating Smad3 phosphorylation, thereby modulating the formation of early fibrotic scars following cerebral ischemic stroke and affecting prognosis. The Sonic Hedgehog signaling pathway may serve as a new therapeutic target for stroke treatment.

Abstract
Ischemic stroke, which is characterized by hypoxia and ischemia, triggers a cascade of injury responses, including neurotoxicity, inflammation, oxidative stress, disruption of the blood-brain barrier, and neuronal death. In this context, tryptophan metabolites and enzymes, which are synthesized through the kynurenine and 5-hydroxytryptamine pathways, play dual roles. The delicate balance between neurotoxic and neuroprotective substances is a crucial factor influencing the progression of ischemic stroke. Neuroprotective metabolites, such as kynurenic acid, exert their effects through various mechanisms, including competitive blockade of N-methyl-D-aspartate receptors, modulation of α7 nicotinic acetylcholine receptors, and scavenging of reactive oxygen species. In contrast, neurotoxic substances such as quinolinic acid can hinder the development of vascular glucose transporter proteins, induce neurotoxicity mediated by reactive oxygen species, and disrupt mitochondrial function. Additionally, the enzymes involved in tryptophan metabolism play major roles in these processes. Indoleamine 2,3-dioxygenase in the kynurenine pathway and tryptophan hydroxylase in the 5-hydroxytryptamine pathway influence neuroinflammation and brain homeostasis. Consequently, the metabolites generated through tryptophan metabolism have substantial effects on the development and progression of ischemic stroke. Stroke treatment aims to restore the balance of various metabolite levels; however, precise regulation of tryptophan metabolism within the central nervous system remains a major challenge for the treatment of ischemic stroke. Therefore, this review aimed to elucidate the complex interactions between tryptophan metabolites and enzymes in ischemic stroke and develop targeted therapies that can restore the delicate balance between neurotoxicity and neuroprotection.

Abstract
In recent years, exosomes have garnered extensive attention as therapeutic agents and early diagnostic markers in neurodegenerative disease research. Exosomes are small and can effectively cross the blood-brain barrier, allowing them to target deep brain lesions. Recent studies have demonstrated that exosomes derived from different cell types may exert therapeutic effects by regulating the expression of various inflammatory cytokines, mRNAs, and disease-related proteins, thereby halting the progression of neurodegenerative diseases and exhibiting beneficial effects. However, exosomes are composed of lipid bilayer membranes and lack the ability to recognize specific target cells. This limitation can lead to side effects and toxicity when they interact with non-specific cells. Growing evidence suggests that surface-modified exosomes have enhanced targeting capabilities and can be used as targeted drug-delivery vehicles that show promising results in the treatment of neurodegenerative diseases. In this review, we provide an up-to-date overview of existing research aimed at devising approaches to modify exosomes and elucidating their therapeutic potential in neurodegenerative diseases. Our findings indicate that exosomes can efficiently cross the blood-brain barrier to facilitate drug delivery and can also serve as early diagnostic markers for neurodegenerative diseases. We introduce the strategies being used to enhance exosome targeting, including genetic engineering, chemical modifications (both covalent, such as click chemistry and metabolic engineering, and non-covalent, such as polyvalent electrostatic and hydrophobic interactions, ligand-receptor binding, aptamer-based modifications, and the incorporation of CP05-anchored peptides), and nanomaterial modifications. Research into these strategies has confirmed that exosomes have significant therapeutic potential for neurodegenerative diseases. However, several challenges remain in the clinical application of exosomes. Improvements are needed in preparation, characterization, and optimization methods, as well as in reducing the adverse reactions associated with their use. Additionally, the range of applications and the safety of exosomes require further research and evaluation.

Neural Regen Res 2026; 21:62-80.

Abstract
Intracerebral hemorrhage is the most dangerous subtype of stroke, characterized by high mortality and morbidity rates, and frequently leads to significant secondary white matter injury. In recent decades, studies have revealed that gut microbiota can communicate bidirectionally with the brain through the gut microbiota-brain axis. This axis indicates that gut microbiota is closely related to the development and prognosis of intracerebral hemorrhage and its associated secondary white matter injury. The NACHT, LRR, and pyrin domain-containing protein 3 (NLRP3) inflammasome plays a crucial role in this context. This review summarizes the dysbiosis of gut microbiota following intracerebral hemorrhage and explores the mechanisms by which this imbalance may promote the activation of the NLRP3 inflammasome. These mechanisms include metabolic pathways (involving short-chain fatty acids, lipopolysaccharides, lactic acid, bile acids, trimethylamine-N-oxide, and tryptophan), neural pathways (such as the vagus nerve and sympathetic nerve), and immune pathways (involving microglia and T cells). We then discuss the relationship between the activated NLRP3 inflammasome and secondary white matter injury after intracerebral hemorrhage. The activation of the NLRP3 inflammasome can exacerbate secondary white matter injury by disrupting the blood-brain barrier, inducing neuroinflammation, and interfering with nerve regeneration. Finally, we outline potential treatment strategies for intracerebral hemorrhage and its secondary white matter injury. Our review highlights the critical role of the gut microbiota-brain axis and the NLRP3 inflammasome in white matter injury following intracerebral hemorrhage, paving the way for exploring potential therapeutic approaches.

Ferroptosis has been demonstrated to be associated with retinal degenerative diseases. However, the molecular mechanisms underlying ferroptosis and photoreceptor cell death in age-related macular degeneration remain largely unexplored. Bioinformatics and biochemical analyses in this study revealed xC - , solute carrier family 7 member 11-regulated ferroptosis as the predominant pathological process of photoreceptor cell degeneration in a light-induced dry age-related macular degeneration mouse model. This process involves the nuclear factor-erythroid factor 2-related factor 2-solute carrier family 7 member 11-glutathione peroxidase 4 signaling pathway, through which cystine depletion, iron ion accumulation, and enhanced lipid peroxidation ultimately lead to photoreceptor cell death and subsequent visual function impairment. We demonstrated that solute carrier family 7 member 11 overexpression blocked this process by inhibiting oxidative stress in vitro and in vivo . Conversely, solute carrier family 7 member 11 knockdown or the solute carrier family 7 member 11 inhibitor sulfasalazine and ferroptosis-inducing agent erastin aggravated H 2 O 2 -induced ferroptosis of 661W cells. These findings indicate solute carrier family 7 member 11 may be a potential therapeutic target for patients with retinal degenerative diseases including age-related macular degeneration.

Abstract
Alzheimer's disease is the primary cause of dementia and imposes a significant socioeconomic burden globally. Physical exercise, as an effective strategy for improving general health, has been largely reported for its effectiveness in slowing neurodegeneration and increasing brain functional plasticity, particularly in aging brains. However, the underlying mechanisms of exercise in cognitive aging remain largely unclear. Adiponectin, a cell-secreted protein hormone, has recently been found to regulate synaptic plasticity and mediate the antidepressant effects of physical exercise. Studies on the neuroprotective effects of adiponectin have revealed potential innovative treatments for Alzheimer's disease. Here, we reviewed the functions of adiponectin and its receptor in the brains of human and animal models of cognitive impairment. We summarized the role of adiponectin in Alzheimer's disease, focusing on its impact on energy metabolism, insulin resistance, and inflammation. We also discuss how exercise increases adiponectin secretion and its potential benefits for learning and memory. Finally, we highlight the latest research on chemical compounds that mimic exercise-enhanced secretion of adiponectin and its receptor in Alzheimer's disease.

Until recently, the functions of border-associated macrophages have been poorly understood and largely overlooked. However, a recent study reported that border-associated macrophages participate in stroke-induced inflammation, although many details and the underlying mechanisms remain unclear. In this study, we performed a comprehensive single-cell analysis of mouse border-associated macrophages using sequencing data obtained from the Gene Expression Omnibus (GEO) database (GSE174574 and GSE225948). Differentially expressed genes were identified, and enrichment analysis was performed to identify the transcription profile of border-associated macrophages. CellChat analysis was conducted to determine the cell communication network of border-associated macrophages. Transcription factors were predicted using the 'pySCENIC' tool. We found that, in response to hypoxia, border-associated macrophages underwent dynamic transcriptional changes and participated in the regulation of inflammatory-related pathways. Notably, the tumor necrosis factor pathway was activated by border-associated macrophages following ischemic stroke. The pySCENIC analysis indicated that the activity of signal transducer and activator of transcription 3 (Stat3) was obviously upregulated in stroke, suggesting that Stat3 inhibition may be a promising strategy for treating border-associated macrophages-induced neuroinflammation. Finally, we constructed an animal model to investigate the effects of border-associated macrophages depletion following a stroke. Treatment with liposomes containing clodronate significantly reduced infarct volume in the animals and improved neurological scores compared with untreated animals. Taken together, our results demonstrate comprehensive changes in border-associated macrophages following a stroke, providing a theoretical basis for targeting border-associated macrophages-induced neuroinflammation in stroke treatment.

[PMID: 39665811 PMCID: PMC12094539 DOI: 10.4103/nrr.nrr-d-24-00665] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2024] [Revised: 07/27/2024] [Accepted: 10/31/2024] [Indexed: 12/13/2024] Open
Abstract
Effective treatment methods for stroke, a common cerebrovascular disease with a high mortality rate, are still being sought. Exosome therapy, a form of acellular therapy, has demonstrated promising efficacy in various diseases in animal models; however, there is currently insufficient evidence to guide the clinical application of exosome in patients with stroke. This article reviews the progress of exosome applications in stroke treatment. It aims to elucidate the significant potential value of exosomes in stroke therapy and provide a reference for their clinical translation. At present, many studies on exosome-based therapies for stroke are actively underway. Regarding preclinical research, exosomes, as bioactive substances with diverse sources, currently favor stem cells as their origin. Due to their high plasticity, exosomes can be effectively modified through various physical, chemical, and genetic engineering methods to enhance their efficacy. In animal models of stroke, exosome therapy can reduce neuroinflammatory responses, alleviate oxidative stress damage, and inhibit programmed cell death. Additionally, exosomes can promote angiogenesis, repair and regenerate damaged white matter fiber bundles, and facilitate the migration and differentiation of neural stem cells, aiding the repair process. We also summarize new directions for the application of exosomes, specifically the exosome intervention through the ventricular-meningeal lymphatic system. The review findings suggest that the treatment paradigm for stroke is poised for transformation.

PHARMACEUTICAL BIOLOGY 2025; 63:250-263. [PMID: 40260854 PMCID: PMC12016237 DOI: 10.1080/13880209.2025.2488994] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/08/2024] [Revised: 03/16/2025] [Accepted: 03/31/2025] [Indexed: 04/24/2025]
Abstract
CONTEXT Myocardial fibrosis is a common manifestation of end-stage cardiovascular disease, but there is a lack of means to reverse fibrosis. Astragaloside IV (AS-IV), the major active component of Astragalus membranaceus Fisch. ex Bunge Fabaceae, possesses diverse biological activities that have beneficial effects against cardiovascular disease. OBJECTIVE This systematic review aims to summarize the anti-fibrosis effect of AS-IV in animal models (rats or mice only) and its underlying mechanisms, and provide potential directions for the clinical use of AS-IV. METHODS PubMed, EMBASE, Web of Science, CNKI, Wanfang database, and SinoMed were searched from inception to 31 December 2024. The following characteristics of the included studies were extracted and summarized: animal model, route of administration, dose/concentration, measurement indicators, and potential mechanisms. The quality of the included studies was assessed used a 10-item scale from SYRCLE. RESULTS AND CONCLUSION AS-IV represents a promising multi-target candidate for myocardial fibrosis treatment in the 24 eligible studies included in the analysis. This systematic review is the first to comprehensively evaluate the anti-fibrosis mechanisms of AS-IV across heterogeneous cardiovascular disease animal models, including myocardial infarction, hypertension, ischemia-reperfusion injury, and myocarditis. The underlying mechanisms of the anti-fibrosis effects of AS-IV may include collagen metabolism, anti-apoptosis, anti-inflammation and, pyroptosis, antioxidants, improving mitochondrial function, regulating senescence, etc. Current evidence remains preclinical, with critical gaps in toxicological profiles, human safety thresholds, and clinical adverse reaction data. Future research must integrate robust toxicological evaluations, optimized combination therapies, and adaptive clinical trials to validate translational potential.

Piezo1 aggravates ischemia/reperfusion-induced acute kidney injury by Ca 2+-dependent calpain/HIF-1α/Notch signaling. Ren Fail 2025; 47:2447801. [PMID: 39780511 PMCID: PMC11721879 DOI: 10.1080/0886022x.2024.2447801] [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: 11/15/2024] [Revised: 12/08/2024] [Accepted: 12/23/2024] [Indexed: 01/11/2025] Open
Abstract
Macrophages play a vital role in the inflammation and repair processes of ischemia/reperfusion-induced acute kidney injury (IR-AKI). The mechanosensitive ion channel Piezo1 is significant in these inflammatory processes. However, the exact role of macrophage Piezo1 in IR-AKI is unknown. The main purpose of this study was to determine the role of macrophage Piezo1 in the injury and repair process in IR-AKI. Genetically modified mice with targeted knockout of Piezo1 in myeloid cells were established, and acute kidney injury was induced by bilateral renal vascular clamping surgery. Additionally, hypoxia treatment was performed on bone marrow-derived macrophages in vitro. Our data indicate that Piezo1 is upregulated in renal macrophages in mice with IR-AKI. Myeloid Piezo1 knockout provided protective effects in mice with IR-AKI. Mechanistically, the regulatory effects of Piezo1 on macrophages are at least partially linked to calpain signaling. Piezo1 activates Ca2+-dependent calpain signaling, which critically upregulates HIF-1α signaling. This key pathway subsequently influences the Notch and CCL2/CCR2 pathways, driving the polarization of M1 macrophages. In conclusion, our findings elucidate the biological functions of Piezo1 in renal macrophages, underscoring its role as a crucial mediator of acute kidney injury. Consequently, the genetic or pharmacological inhibition of Piezo1 presents a promising strategy for treating IR-AKI.

Abstract
Cysteinyl leukotrienes (CysLTs), as potent lipid inflammatory mediators, play a pivotal role in systemic multi-organ inflammation and inter-organ communication through interactions with their receptors (CysLTRs). However, However, the function of CysLT3R is unclear and lacks a network of cross-organ metabolite interactions, and the clinical use of leukotriene receptor antagonists (LTRAs) has certain limitations. This review systematically synthesizes existing evidence and proposes future directions by clarifying receptor subtype specificity, optimizing targeted therapies, exploring CysLTs' applications in neuroimmunology, and elucidating the dual roles of CysLTs in chronic inflammation. It is indicated that CysLTs activate eosinophils, mast cells, and airway tuft cells, driving type 2 immune responses and mucus secretion in the lungs, thereby exacerbating respiratory diseases such as asthma. In the nervous system, CysLTs aggravate neurodegenerative disorders like cerebral ischemia and Alzheimer's disease by disrupting the blood-brain barrier, promoting glial activation, and inducing neuronal damage. In the gut, CysLTs regulate anti-helminth immunity via the tuft cell-ILC2 pathway and collaborate with prostaglandin D2 (PGD2) to modulate bile excretion and mucosal protection. Furthermore, CysLTs mediate communication through the gut-lung and gut-brain axes via metabolites such as succinate, contributing to cross-organ inflammatory regulation. In conclusion, this review highlights the complex roles of CysLTs in chronic inflammation, providing a theoretical foundation for precise intervention in multi-organ inflammatory diseases, which provides a theoretical framework for precision interventions in multi-organ inflammatory diseases and inspires interdisciplinary breakthroughs.

Abstract
BACKGROUND The difference between the cystatin C-based eGFR (eGFRcys) and the creatinine-based eGFR (eGFRcr) is associated with the risk of developing atrial fibrillation (AF) risk. However, its impact on AF ablation outcomes is unknown. METHODS The associations between the baseline eGFR ratio (eGFRcys/eGFRcr) and the risk of experiencing post-ablation endpoints were evaluated on a continuous scale (restricted cubic splines) and by a priori defined centile categories with Cox proportional hazards regression models. The primary endpoints were AF recurrence and adverse events; the secondary endpoint was rehospitalization. RESULTS Among 989 participants (49.2% women; mean age 65.7 years), 313 experienced AF recurrence after a median follow-up of 28 months. After full adjustment for confounding factors, a U-shaped association was observed between eGFR ratio and AF recurrence risk (minimum risk at 0.797). Although a U-shaped trend was observed, there was no statistically significant association between the eGFR ratio and adverse events or rehospitalization. Hazard ratios for AF recurrence, compared to the second quartile, were 1.68 (1.20-2.37) for the first quartile, 1.64 (1.15-2.34) for the third quartile, and 1.96 (1.37-2.80) for the fourth quartile. According to the subgroup analysis, the above association was strongly U-shaped for males and linear for females. CONCLUSION In the AF population, both low and high eGFR ratios were associated with an increased risk of post-ablation AF recurrence.

Abstract
BACKGROUND The triglyceride glucose-body mass index (TyG-BMI), fasting blood glucose (FBG) to high-density lipoprotein cholesterol (HDL-C) ratio (GHR), and platelet (PLT) to HDL-C ratio (PHR) are well-established markers of insulin resistance (IR), closely linked to cardiovascular and cerebrovascular diseases. Abdominal aortic calcification (AAC), a key indicator of subclinical atherosclerotic, is highly prevalent in maintenance hemodialysis (MHD) patients. This study aimed to explore the cross-sectional relationship between these IR indices and AAC in MHD patients and identify the most reliable predictive marker. METHODS We recruited 391 MHD patients from two hemodialysis medical centers, with 297 meeting the inclusion criteria. AAC was detected via X-ray scanning of the lumbar spine, quantified by the Kauppila scoring system. Receiver operating characteristic (ROC) curve analysis determined optimal cutoff values for dividing the subjects into high-index and low-index groups. Multivariable logistic regression models evaluated the association between AAC and these IR indices. RESULTS The prevalence of AAC in the whole group was 72.4%. The occurrence of AAC in the high-index group was significantly higher than that in the low-index group. Among the three IR indices, PHR demonstrated the highest predictive stability when integrated into a combined model. Subgroup analyses confirmed the robustness of this association across different age groups, sex, hypertension levels, comorbidities (CVD and stroke history), and smoking status. CONCLUSION TyG-BMI, GHR and PHR were independently associated with the presence of AAC among MHD patients. Notably, PHR showed the strongest correlation with AAC, suggesting its potential clinical utility in risk stratification.

Abstract
BACKGROUND Preterm birth, a significant global health concern, has been associated with alterations in the gut microbiota. However, the causal nature of this relationship remains uncertain due to the limitations inherent in observational studies. PURPOSE To investigate the potential causal relationship between gut microbiota imbalances and preterm birth. METHODS We conducted a two-sample Mendelian randomization (MR) study using genome-wide association study (GWAS) data from the MiBioGen consortium focusing on microbiota and preterm birth. Single nucleotide polymorphisms (SNPs) associated with the microbiota were selected as instrumental variables. The inverse variance weighting (IVW) method was used to estimate causality. We confirmed pleiotropy and identified and excluded outlier SNPs using MR-PRESSO and MR-Egger regression. Cochran's Q test was applied to assess heterogeneity among SNPs, and a leave-one-out analysis was performed to evaluate the influence of individual SNPs on overall estimates. RESULTS Our findings provide evidence for a causal link between specific components of the gut microbiota and preterm birth, with the identification of relevant metabolites. CONCLUSION This study highlights the causal role of gut microbiota imbalances in preterm birth, offering novel insights into the development of preterm birth and potential targets for prevention strategies.

Abstract
INTRODUCTION The BIC-T&T study aimed to determine the efficacy of bictegravir/emtricitabine/tenofovir alafenamide (BIC/F/TAF) and darunavir/cobicistat/emtricitabine/tenofovir alafenamide (DRV/c/F/TAF) at suppressing viral load in a two-arm, open-label, multi-centre, randomised trial under a UK test-and-treat setting. This sub-study aimed to evaluate potential off-target cardiovascular impact by examining ex vivo platelet function. METHODS Platelets were isolated by centrifugation of citrated blood from participants attending Chelsea and Westminster Hospital or St Mary's Hospital at Week 48 following enrolment. Platelet activation was assessed by real-time flow cytometry to examine integrin activation and granule release and platelet aggregation was evaluated by light transmission aggregometry. Statistical significance was determined by 2-way ANOVA with a Šidák's multiple comparisons post-test. RESULTS An analysis of 21 participants was performed at Week 48 (96% male and 48% white; mean (range) age was 37 (23-78) years). No difference between arms was observed in ADP-, collagen- or thrombin receptor activator for peptide (TRAP)-6-evoked platelet αIIbβ3 integrin activation, granule release or platelet aggregation in response to any of the agonists tested. Despite differences in the demographics between treatment arms, the presence of an unboosted integrase inhibitor or boosted protease inhibitor in a test-and-treat setting did not impact platelet function. CONCLUSIONS Our study provides no evidence of differences in downstream platelet responses between participants taking BIC/F/TAF compared to DRV/c/F/TAF following 48 wk of treatment. Further data are required to explore whether there are biologically significant off-target effects, including effects on platelets and other components of the cardiovascular system between these two test-and-treat regimens. CLINICAL TRIAL NUMBER NCT04653194.

Abstract
Over the past 25 years, nuclear envelope (NE) perturbations have been reported in various experimental models with mutations in the LMNA gene. Although the hypothesis that NE perturbations from LMNA mutations are a fundamental feature of striated muscle damage has garnered wide acceptance, the molecular sequalae provoked by the NE damage and how they underlie disease pathogenesis such as cardiomyopathy (LMNA cardiomyopathy) remain poorly understood. We recently shed light on one such consequence, by employing a cardiomyocyte-specific Lmna deletion in vivo in the adult heart. We observed extensive NE perturbations prior to cardiac function deterioration with collateral damage in the perinuclear space. The Golgi is particularly affected, leading to cytoprotective stress responses that are likely disrupted by the progressive deterioration of the Golgi itself. In this review, we discuss the etiology of LMNA cardiomyopathy with perinuclear 'organelle trauma' as the nexus between NE damage and disease pathogenesis.

Abstract
Chronic kidney disease (CKD) poses a severe health risk with high morbidity and mortality, profoundly affecting patient quality of life and survival. Despite advancements in research, the pathophysiology of CKD remains incompletely understood. Growing evidence links CKD with shifts in gut microbiota function and composition. Natural compounds, particularly polyphenols, have shown promise in CKD treatment due to their antioxidant and anti-inflammatory properties and their ability to modulate gut microbiota. This review discusses recent progress in uncovering the connections between gut microbiota and CKD, including microbiota changes across different kidney diseases. We also examine metabolite alterations,such as trimethylamine-N-oxide, tryptophan derivatives, branched-chain amino acids, short-chain fatty acids, and bile acids,which contribute to CKD progression. Further, we outline the mechanisms through which polyphenols exert therapeutic effects on CKD, focusing on signaling pathways like nuclear factor kappa-B (NF-κB), mitogen-activated protein kinase (MAPK), mammalian target of rapamycin (mTOR), NOD-like receptor thermal protein domain associated protein 3 (NLRP3), phosphatidylin-ositol-3-kinase (PI3K)/protein kinase B (Akt), and toll like receptors (TLR), as well as their impact on gut microbiota. Lastly, we consider how dietary polyphenols could be harnessed as bioactive drugs to slow CKD progression. Future research should prioritize multi-omics approaches to identify patients who would benefit from polyphenolic interventions, enabling personalized treatment strategies to enhance therapeutic efficacy.

Aging Male 2025; 28:2498943. [PMID: 40325946 DOI: 10.1080/13685538.2025.2498943] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2024] [Revised: 04/12/2025] [Accepted: 04/23/2025] [Indexed: 05/07/2025] Open
Abstract
BACKGROUND Benign prostatic hyperplasia (BPH) is a common condition that affects elderly men, but its relationship with central obesity in the American population has not been adequately elucidated. METHODS In this study, we included a total of 4,625 participants from the National Health and Nutrition Examination Survey (NHANES) database spanning from 2001 to 2008. We calculated indices related to central obesity for each participant and then employed univariate logistic regression, multivariate logistic regression, restricted cubic splines (RCS), and Akaike's Information Criterion (AIC) analysis. RESULTS we found that the indices of Weight, Waist Circumference (WC), waist-to-Height Ratio (WHtR), and Body Roundness Index (BRI) were significantly elevated in the BPH group. In terms of dietary intake, we found that the intake of total fat, saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids, and cholesterol was significantly higher in the BPH group, with polyunsaturated fatty acids and cholesterol meeting the criteria for both univariate and multivariate regression analyses. CONCLUSION Weight, WC, WHtR, and BRI can effectively improve the prediction of BPH, which may be associated with the high intake of polyunsaturated fatty acids and cholesterol. Appropriately adjusting the types and total amount of fat intake may prevent the occurrence of prostatic hyperplasia.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disease and its prevalence has risen sharply. However, whether nutrition, dietary strategies, exercise, lifestyle and environment have preventive value for NAFLD remains unclear. METHODS Through searching 4 databases (PubMed, Web of Science, Embase and the Cochrane Library) from inception to January 2025, we selected studies about nutrition, dietary strategies, exercise, lifestyle and environment in the prevention of NAFLD and conducted a narrative review on this topic. RESULTS Reasonable nutrient intake encompassing macronutrients and micronutrients have an independent protective relationship with NAFLD. Besides, proper dietary strategies including mediterranean diet, intermittent fasting diet, ketogenic diet, and dietary approaches to stop hypertension diet have their inhibitory effects on the developmental process of NAFLD. Moreover, right exercises including walking, jogging, bicycling, and swimming are recommended for the prevention of NAFLD because they could effectively reduce weight, which is an important risk factor for NAFLD, and improve liver function. In addition, embracing a healthy lifestyle including reducing sedentary behavior, not smoking, sleeping well and brushing teeth regularly is integral since it not only could reduce the risk of NAFLD but also significantly contribute to overall prevention and control. Finally, the environment, including the social and natural environments, plays a potential role in NAFLD prevention. CONCLUSION Nutrition, dietary strategies, exercise, lifestyle and environment play an important role in the prevention of NAFLD. Moreover, this review offers comprehensive prevention recommendations for people at high risk of NAFLD.

Abstract
The nuclear envelope plays an indispensable role in the spatiotemporal organization of chromatin and transcriptional regulation during the intricate process of cell differentiation. This review outlines the distinct regulatory networks between nuclear envelope proteins, transcription factors and epigenetic modifications in controlling the expression of cell lineage-specific genes during differentiation. Nuclear lamina with its associated nuclear envelope proteins organize heterochromatin via Lamina-Associated Domains (LADs), proximal to the nuclear periphery. Since nuclear lamina is mechanosensitive, we critically examine the impact of extracellular forces on differentiation outcomes. The nuclear envelope is spanned by nuclear pore complexes which, in addition to their central role in transport, are associated with chromatin organization. Furthermore, mutations in the nuclear envelope proteins disrupt differentiation, resulting in developmental disorders. Investigating the underlying nuclear envelope controlled regulatory mechanisms of chromatin remodelling during lineage commitment will accelerate our fundamental understanding of developmental biology and regenerative medicine.

Abstract
The vascular network, uniquely sensitive to mechanical changes, translates biophysical forces into biochemical signals for vessel function. This process relies on the cell's architectural integrity, enabling uniform responses to physical stimuli. Recently, the nuclear envelope (NE) has emerged as a key regulator of vascular cell function. Studies implicate nucleoskeletal elements (e.g. nuclear lamina) and the linker of nucleoskeleton and cytoskeleton (LINC) complex in force transmission, emphasizing nucleo-cytoskeletal communication in mechanotransduction. The nuclear pore complex (NPC) and its component proteins (i.e. nucleoporins) also play roles in cardiovascular disease (CVD) progression. We herein summarize evidence on the roles of nuclear lamina proteins, LINC complex members, and nucleoporins in endothelial and vascular cell mechanotransduction. Numerous studies attribute NE components in cytoskeletal-related cellular behaviors to insinuate dysregulation of nucleocytoskeletal feedback and nucleocytoplasmic transport as a mechanism of endothelial and vascular dysfunction, and hence implications for aging and vascular pathophysiology.

Gut Microbes 2025; 17:2474142. [PMID: 40025767 PMCID: PMC11881840 DOI: 10.1080/19490976.2025.2474142] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2024] [Revised: 02/03/2025] [Accepted: 02/25/2025] [Indexed: 03/04/2025] Open
Abstract
Obstructive sleep apnea (OSA) is characterized by intermittent hypoxia/hypercapnia (IHC), affects predominantly obese individuals, and increases atherosclerosis risk. Since we and others have implicated gut microbiota and metabolites in atherogenesis, we dissected their contributions to OSA-induced atherosclerosis. Atherosclerotic lesions were compared between conventionally-reared specific pathogen free (SPF) and germ-free (GF) Apoe-/- mice following a high fat high cholesterol diet (HFHC), with and without IHC conditions. The fecal microbiota and metabolome were profiled using 16S rRNA gene amplicon sequencing and untargeted tandem mass spectrometry (LC-MS/MS) respectively. Phenotypic data showed that HFHC significantly increased atherosclerosis as compared to regular chow (RC) in both aorta and pulmonary artery (PA) of SPF mice. IHC exacerbated lesions in addition to HFHC. Differential abundance analysis of gut microbiota identified an enrichment of Akkermansiaceae and a depletion of Muribaculaceae (formerly S24-7) family members in the HFHC-IHC group. LC-MS/MS showed a dysregulation of bile acid profiles with taurocholic acid, taurodeoxycholic acid, and 12-ketodeoxycholic acid enriched in the HFHC-IHC group, long-chain N-acyl amides, and phosphatidylcholines. Interestingly, GF Apoe-/- mice markedly reduced atherosclerotic formation relative to SPF Apoe-/- mice in the aorta under HFHC/IHC conditions. In contrast, microbial colonization did not show a significant impact on the atherosclerotic progression in PA. In summary, this research demonstrated that (1) IHC acts cooperatively with HFHC to induce atherosclerosis; (2) gut microbiota modulate atherogenesis, induced by HFHC/IHC, in the aorta not in PA; (3) different analytical methods suggest that a specific imbalance between Akkermansiaceae and Muribaculaceae bacterial families mediate OSA-induced atherosclerosis; and (4) derived bile acids, such as deoxycholic acid and lithocholic acid, regulate atherosclerosis in OSA. The knowledge obtained provides novel insights into the potential therapeutic approaches to prevent and treat OSA-induced atherosclerosis.

Abstract
People with HIV are at increased risk of cardiovascular events; thus, care delivery strategies that increase access to comprehensive cardiovascular disease (CVD) risk management are a priority. We report the results of a multi-component telemedicine-based strategy to improve blood pressure control among people with HIV-Assess and Adapt to the Impact of COVID-19 on CVD Self-Management and Prevention Care in Adults Living with HIV (AAIM-High). The AAIM High strategy is a virtual adaptation of our previously published EXTRA-CVD strategy and consisted of hypertension education and six components: nurse-led care coordination (delivered by teleconference or telephone), home systolic blood pressure (SBP) monitoring, evidence-based treatment algorithms, electronic health records tools, technology coach, and communication preferences assessment. People with HIV (n = 74) with comorbid hypertension at three academic medical centers were enrolled in a single arm implementation study from January 2021 to December 2022. Over 12 months, the average patient-performed home SBP decreased by 7.7 mmHg (95% CI -11.5, -3.9). The percentage of patients at treatment goal, defined as average SBP <130 mmHg, increased from 46.0% to 72.5% at 12 months. By adapting to the growing use of telemedicine in healthcare delivery, our study effectively improved hypertension control in people with HIV through a virtual, nurse-led intervention.

Abstract
Poststroke cognitive impairments (PSCI) reflect widespread network dysfunction due to structural damage, abnormal neural activity, or abnormal connections in affected brain regions. The exact influence of these lesioned regions on the related functional network and their role in PSCI remains unclear. We recruited 35 first-time stroke patients who had basal ganglia infarcts and PSCI, along with 29 age-matched healthy controls. We utilized T1-weighted imaging to inspect structural damage with regional gray matter volume (GMV). Resting-state fMRI data were utilized to examine spontaneous activities with regional Wavelet-ALFF metric, investigate dynamic functional connectivity (dFC) by seeding the region with damaged GMV, and further study effective connectivity within the abnormal dFC network and its impact on PSCI. In comparison to HC, patients showed significant reduced GMV in the bilateral Rolandic operculum (ROL), along with notable abnormal Wavelet-ALFF values in the right Precuneus (PCUN) and left Cerebellum_9 (CER9). Particularly, an abnormal dFC network seeded in the left ROL, demonstrating significantly differential between PSCI and HC groups and remaining consistent across all time windows, was observed. This abnormal dFC network comprised the left ROL as the seed region, the right ROL, bilateral PCUN, bilateral CER9, right Superior Temporal Gyrus (STG), and right Parahippocampal Gyrus (PHG). Notably, in patients, impaired functions across various cognitive domains significantly influenced the altered effective connections among the abnormal regions, particularly impacting the connections between structurally damaged regions and those with abnormal spontaneous activity. These findings suggest that altered effective connectivity networks within lesioned regions may contribute to deficits in various cognitive domains in PSCI.

Abstract
In recent years, findings suggest that long noncoding RNAs (lncRNAs) are closely related to the development of atherosclerosis (AS), but there is a lack of studies on the involvement of lncRNA-regulated cytosolic burial in the regulation of AS. In this study, we investigated the mechanism by which lncRNA SCARNA8 affects macrophage cell burial to regulate AS. The cytosolic burial-associated target gene regulated by lncRNA SCARNA8 was PPARG. LncRNA SCARNA8 was increased in the carotid unstable plaque group, whereas PPARG was decreased. Ox-LDL led to the up-regulation of lncRNA SCARNA8 expression and apoptosis in Raw264.7 cells in a time-, concentration-dependent manner. Knockdown of lncRNA SCARNA8 upregulated PPARG and reduced apoptosis in Raw264.7 cells. In addition, knockdown of lncRNA SCARNA8 improved the stability of atherosclerotic plaques by promoting cellular burial of Raw264.7 cells. LncRNA SCARNA8 is a key regulator of plaque vulnerability, and targeting lncRNA SCARNA8 May provide a novel means for the prevention and treatment of AS.

Abstract
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia characterized by consistently irregular atrial and ventricular contractions. Heart rate variability (HRV) refers to the changes in the intervals between consecutive ventricular heartbeats. In sinus rhythm, HRV may be subtle and is quantitatively reflecting the dynamic interplay of the cardiac autonomic nervous system, which plays a crucial role in the onset, development, and maintenance of AF. HRV metrics, consisting of time-domain, frequency-domain, and nonlinear parameters, have been verified to vary significantly before and after AF episodes, and AF treatment-related procedures such as electrical cardioversion, ablation, and surgery of AF. Therefore, HRV may serve as a digital biomarker in predicting AF risk in long-term and acute risk period, identification of patients with AF risk in sinus rhythm and recurrence risk stratification after procedures. HRV in AF rhythm, predominantly influenced by dynamic atrioventricular node conduction under the onslaught of irregular atrial impulses, shows a huge disparity compared to that in sinus rhythm. Despite this, HRV in AF rhythm still provides valuable prognostic information, as reduced HRV may indicate a poor heart function and outcomes in patients with AF. Despite being influenced by lots of variables, HRV can still serve as an independent digital biomarker in the clinical management of AF throughout its entire lifecycle.

Abstract
The kidney is essential for lactate metabolism. Under normal conditions, the renal cortex mainly absorbs and metabolizes lactate, with minimal amounts excreted in urine. This process is part of a glucose-lactate recycling system between the cortex and medulla. In conditions such as acute kidney injury (AKI) and diabetic kidney disease (DKD), the kidney's ability to metabolize lactate is impaired, leading to lactate accumulation and exacerbated renal dysfunction. Novel post-translational modifications, such as lactylation, are critical in kidney disease pathophysiology by modulating gene transcription, protein function, and cellular metabolism. Lactylation is involved in inflammatory responses and tumor promotion in AKI, mitochondrial dysfunction in DKD, and tumor progression in clear cell renal cell carcinoma (ccRCC). The lactate-lactylation axis is central to the Warburg effect in ccRCC, where tumor cells preferentially rely on glycolysis rather than oxidative phosphorylation. Understanding the mechanisms of lactate metabolism and lactylation in kidney diseases may offer new therapeutic strategies. This review examines the role of lactate esters, especially lactylation, in kidney diseases, with a focus on their regulatory mechanisms and potential as therapeutic targets.

Gut microbiota modulation via fecal microbiota transplantation mitigates hyperoxaluria and calcium oxalate crystal depositions induced by high oxalate diet. Gut Microbes 2025; 17:2457490. [PMID: 39873191 PMCID: PMC11776474 DOI: 10.1080/19490976.2025.2457490] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2024] [Revised: 12/16/2024] [Accepted: 01/17/2025] [Indexed: 01/30/2025] Open
Abstract
Hyperoxaluria, including primary and secondary hyperoxaluria, is a disorder characterized by increased urinary oxalate excretion and could lead to recurrent calcium oxalate kidney stones, nephrocalcinosis and eventually end stage renal disease. For secondary hyperoxaluria, high dietary oxalate (HDOx) or its precursors intake is a key reason. Recently, accumulated studies highlight the important role of gut microbiota in the regulation of oxalate homeostasis. However, the underlying mechanisms involving gut microbiota and metabolite disruptions in secondary hyperoxaluria remain poorly understood. Here, we investigated the therapeutic efficacy of fecal microbiota transplantation (FMT) sourced from healthy rats fed with standard pellet diet against urinary oxalate excretion, renal damage and calcium oxalate (CaOx) crystal depositions via using hyperoxaluria rat models. We observed dose-dependent increases in urinary oxalate excretion and CaOx crystal depositions due to hyperoxaluria, accompanied by significant reductions in gut microbiota diversity characterized by shifts in Ruminococcaceae_UCG-014 and Parasutterella composition. Metabolomic analysis validated these findings, revealing substantial decreases in key metabolites associated with these microbial groups. Transplanting microbes from healthy rats effectively reduced HDOx-induced urinary oxalate excretion and CaOx crystal depositions meanwhile restoring Ruminococcaceae_UCG-014 and Parasutterella populations and their associated metabolites. Furthermore, FMT treatment could significantly decrease the urinary oxalate excretion and CaOx crystal depositions in rat kidneys via, at least in part, upregulating the expressions of intestinal barrier proteins and oxalate transporters in the intestine. In conclusion, our study emphasizes the effectiveness of FMT in countering HDOx-induced hyperoxaluria by restoring gut microbiota and related metabolites. These findings provide insights on the complex connection between secondary hyperoxaluria caused by high dietary oxalate and disruptions in gut microbiota, offering promising avenues for targeted therapeutic strategies.

Causal relationship between chronic kidney disease, renal function, and venous thromboembolism: a bidirectional Mendelian randomization study. Ren Fail 2025; 47:2496803. [PMID: 40321038 PMCID: PMC12054574 DOI: 10.1080/0886022x.2025.2496803] [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: 11/01/2024] [Revised: 04/01/2025] [Accepted: 04/15/2025] [Indexed: 05/08/2025] Open
Abstract
BACKGROUND Chronic kidney disease (CKD) and impaired renal function have been implicated in venous thromboembolism (VTE), but their causal relationships remain uncertain. This study employs Mendelian randomization (MR) to elucidate the potential bidirectional causal effects between CKD, renal function biomarkers, and VTE. METHODS We collated datasets from genome-wide association studies conducted among European individuals to perform MR analyses. The primary method utilized was the random-effect inverse variance-weighted (IVW) approach, with MR-Egger and the weighted median approaches employed as supplemental techniques. Several sensitivity studies were performed to assess the findings' robustness. RESULTS We identified a link between elevated serum creatinine levels and both VTE (OR: 1.14, 95% CI: 1.05-1.24, p = 0.001) and PE (OR: 1.20, 95% CI: 1.08-1.33, p = 0.001). After outlier removal and Bonferroni correction, the Cr-VTE association lost significance (p = 0.005). A suggestive causal relationship was found between eGFR and VTE (OR: 0.38, 95% CI: 0.20-0.73, p = 0.004), DVT (OR: 0.37, 95% CI: 0.16-0.87, p = 0.022), and PE (OR: 0.29, 95% CI: 0.12-0.66, p = 0.004). No causal effects of CKD or BUN on VTE or its subtypes were observed. Reverse causality inferences did not reveal any meaningful results. CONCLUSIONS This MR analysis provides evidence that elevated serum creatinine is associated with a higher risk of VTE and PE, while reduced eGFR may be a potential risk factor for VTE and its subtypes. These findings highlight the need for proactive monitoring and preventive strategies in individuals with impaired renal function. Further studies are warranted to confirm these associations and explore underlying mechanisms.

Abstract
Acute lung injury (ALI) is a life-threatening condition with high rates of morbidity and mortality. Recently, there has been growing evidence suggesting a link between lncRNA HOTAIR and ALI. Nonetheless, the precise role and mechanism of lncRNA HOTAIR in ALI remain to be fully elucidated. siHOTAIR transfection, qPCR detection (HOTAIR), ELISA (TNF-α, IL-6, and IL-1β), Lactate detection, Glucose uptake experiment, Cell Apoptosis Analysis, Fluorescence in situ hybridization (FISH) assay. Through siHOTAIR transfection, we discovered that HOTAIR plays a role in the secretion of inflammatory factors in ALI and further regulates glucose uptake and metabolism in lung epithelial cells. Moreover, a comparison between HOTAIR knockdown cells and HOTAIR overexpression cells revealed that HOTAIR promotes cellular aerobic sugar metabolism, leading to increased secretion of inflammatory factors and cell apoptosis. Our in-depth research also identified an interaction between HOTAIR and the LIN28 protein. Knocking down HOTAIR resulted in the downregulation of LIN28 protein expression, which subsequently inhibited the expression of the glucose transporter GLUT1. This indicates that HOTAIR facilitates glucose uptake and boosts cellular aerobic glycolysis by modulating the LIN28 protein, thereby promoting inflammation and apoptosis in acute lung injury. The research findings presented in this article offer significant insights into the function of HOTAIR in ALI and suggest a potential therapeutic target for the treatment of this condition.

Abstract
PURPOSE Ventricular-arterial coupling (VAC) is a crucial concept in cardiovascular physiology, representing the dynamic interaction between the left ventricle and the arterial system. This comprehensive literature review explores the changes in VAC with ageing and various cardiovascular diseases (CVDs). MATERIALS AND METHODS This literature review covers studies on changes in VAC with age and common CVDs, such as arterial hypertension, atrial fibrillation (AF) and heart failure with preserved and reduced ejection fraction and aortic stenosis (AS). The review discusses traditional measures of VAC, including arterial elastance (Ea) and ventricular elastance (Ees), as well as emerging parameters, such as global longitudinal strain (GLS) and pulse wave velocity (PWV). The review introduces the PWV/GLS ratio as a novel method for assessing VAC. RESULTS With ageing, both Ea and Ees increase, while the Ea/Ees ratio remains relatively stable, reflecting balanced arterial and ventricular adaptations. Novel measures, such as PWV/GLS ratio, show greater impairment in older adults and provide a comprehensive evaluation of VAC. CONCLUSIONS Ageing disrupts VAC through arterial stiffening and reduced heart function, often exacerbated by CVDs. Novel metrics like PWV/GLS may improve VAC assessment, helping clinicians manage age-related cardiovascular issues by identifying risks earlier and guiding treatment to support efficient heart-artery interaction.

Abstract
Atherosclerosis is the primary cause of cardiovascular and cerebrovascular diseases. However, current anti-atherosclerosis drugs have shown conflicting therapeutic outcomes, thereby spurring the search for novel and effective treatments. Recent research indicates the crucial involvement of oral and gastrointestinal microbiota in atherosclerosis. While gut microbiota metabolites, such as choline derivatives, have been extensively studied and reviewed, emerging evidence suggests that bacterial extracellular vesicles (BEVs), which are membrane-derived lipid bilayers secreted by bacteria, also play a significant role in this process. However, the role of BEVs in host-microbiota interactions remains insufficiently explored. This review aims to elucidate the complex communication mediated by BEVs along the gut-heart axis. In this review, we summarize current knowledge on BEVs, with a specific focus on how pathogen-derived BEVs contribute to the promotion of atherosclerosis, as well as how BEVs from gut symbionts and probiotics may mitigate its progression. We also explore the potential and challenges associated with engineered BEVs in the prevention and treatment of atherosclerosis. Finally, we discuss the benefits and challenges of using BEVs in atherosclerosis diagnosis and treatment, and propose future research directions to address these issues.

Abstract
In comparison to mature platelets, reticulated platelets (RPs) are newly released from the bone marrow and exhibit a larger size, higher reactivity, and a greater quantity of RNA, and can be an agile indicator of platelet turnover. The transcriptome associated with platelet function is significantly upregulated in RPs, which is a possible explanation for RPs intrinsic hyper-reactivity. We presented a comprehensive overview of the detection techniques for RPs. Current methods to quantify RPs in clinical routine are flow cytometry and fully automated hematology analyzers (Sysmex-XE/XN, Abbott, ADVIA, Mindray), which make the detection of RPs simpler, faster and more affordable. The proportion of RPs increased in the circulation has potential diagnostic and prognostic values in multiple clinical settings (risk stratification in cardiovascular diseases, the effect on antiplatelet drugs, differential diagnosis of thrombocytopenia, monitor platelet recovery after bone marrow or stem cell transplantation, and other diseases). There have been several studies focusing on RPs in recent years, particularly in cardiovascular disease and thrombocytopenia. In this review we summarizes the current study with regard to RPs and discuss their likely contribution in clinical routine.

Abstract
BACKGROUND Patients with end-stage kidney disease undergoing chronic hemodialysis (HD) have an unparalleled risk of vascular calcification (VC) and high alkaline phosphatase (Alk-P) levels. However, whether VC contributed to the cardiovascular risk modified by serum Alk-P levels was not addressed in the population. METHODS A retrospective cohort study was conducted on chronic HD patients, between October 1 and December 31, 2018, with aortic arch calcification (AoAC) scores and serum Alk-P levels. Patients were categorized into four groups: non-to-mild AoAC/low Alk-P, non-to-mild AoAC/high Alk-P, moderate-to-severe AoAC/low Alk-P, and moderate-to-severe AoAC/high Alk-P. The Cox proportional hazard model and Kaplan-Meier analysis were used to evaluate the risks of major adverse cardiovascular effects (MACEs) and cardiovascular and all-cause mortality after multivariate adjustment. RESULTS Among 376 chronic HD patients recruited, 125 (33%) had non-to-mild AoAC/low Alk-P, 76 (20%) had non-to-mild AoAC/high Alk-P, 89 (24%) had moderate-to-severe AoAC/low Alk-P, and 86 (23%) had moderate-to-severe AoAC/high Alk-P. After 3 years of follow-up, patients with coexisting moderate-to-severe AoAC and high Alk-P had a higher risk of MACEs (aHR 1.76; 95% CI 1.06-2.92), and cardiovascular (aHR 2.49; 95% CI 1.21-5.11) and all-cause mortality (aHR 2.67; 95% CI 1.39-5.13) compared to those with non-to-mild AoAC/low Alk-P even after adjustments for significant clinical variables. CONCLUSIONS In chronic HD patients, moderate to severe AoAC co-existed with high Alk-P levels and enhanced the risk of MACEs and cardiovascular and all-cause mortality. Interventions to attenuate these risk factors simultaneously should be emphasized in this population.

Abstract
Refractory pulmonary diseases, including chronic obstructive pulmonary disease (COPD) and tuberculosis (TB), pose a critical global health challenge due to the limitations of conventional therapies in advanced stages, such as poor drug penetration, systemic side effects, and inability to eradicate pathogens in protected microenvironments. While the lung's complex structure is essential for respiratory function, it also facilitates persistent damage from environmental and infectious agents. Nanomedicine provides a transformative approach by utilizing customizable carriers (e.g., ligand-gated targeting, stimuli-responsive payload release) to bypass physiological barriers through both passive mechanisms such as enhanced vascular permeability and active-targeting. Such platforms achieve hierarchical drug deposition-from organ-level accumulation to pneumonocyte-targeting-thereby addressing the spatial heterogeneity of therapy-resistant lesions. Besides, A unique advantage of nanomedicine lies in its intrinsic interactions with lung immune cells (e.g., macrophages), allowing dual-functional systems that not only deliver therapeutics to disease sites but also modulate local immune responses-such as reducing inflammation in COPD or enhancing bacterial clearance in TB. This targeted approach improves treatment efficacy while minimizing systemic toxicity. Furthermore, nanomedicine ensures the stability of encapsulated drugs, particularly nucleic acid therapeutics (siRNA, mRNA), which are crucial for treating genetic defect-related pulmonary diseases. Building on the relationship between malignant pulmonary conditions and lung cells, this review summarizes nanoplatform-based strategies for precise targeting and examines ongoing clinical trials. By bridging the gap between preclinical research and clinical application, this review aims to guide the development of novel therapeutic approaches and accelerate the clinical translation of nanomedicines for refractory pulmonary diseases.

In vivo assessment of iPSC-cardiomyocyte loaded auxetic cardiac patches following chronic myocardial infarction. Biomaterials 2025; 323:123418. [PMID: 40408975 DOI: 10.1016/j.biomaterials.2025.123418] [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: 05/08/2025] [Accepted: 05/18/2025] [Indexed: 05/25/2025]
Abstract
Novel cardiac patch designs achieved by advanced 3D manufacturing continue to have favorable impacts on the repair and regeneration of the myocardium after injury. Briefly, auxetic units with a negative Poisson's ratio have already shown remarkable promise for serving as a next-generation complex scaffold in left ventricular disease. In this study we biofabricated a 3D printed polycaprolactone (PCL) cardiac auxetic patch loaded with high density contractile induced pluripotent stem cell-derived cardiomyocytes (iCMs) and examined the synergist effect of iCM auxetic patches on a chronic myocardial infarct rodent model compared to a stiffer non-auxetic control patch architecture. A week after the induction of a temporary left anterior descending artery ligation, we administered the treatment groups in the form of patch implantation over the ischemic area after initial acute inflammation was complete and prior to granulation tissue formation following the infarct for clinical relevance. Our findings highlight that auxetic patches can provide additional ventricular support and diminished adverse ventricular remodeling, as seen through ejection fraction outputs and histology, and iCM-laden auxetics show localized regenerative potential through increased vascularization compared to controls with no patch or a non-auxetic patch architecture. Exploration on the impact of a negative Poisson's ratio on both global functional outcomes and local therapeutic benefit highlights that iCM-laden auxetics should be further surveyed for other cardiac pathophysiologic conditions, including more in-depth studies on infarction or right ventricular disease.

Abstract
As one of the three major malignant tumors in women, the morbidity of endometrial cancer is second only to that of cervical cancer and is increasing yearly. Its etiological mechanism is not clear, and the risk factors are numerous and common and are closely related to obesity, hypertension, diabetes, etc. The gut microbiota has many strains, which play a considerable part in normal digestion and absorption in the human body and the regulation of the immune response. In the last few years, research on the gut microbiota has been unprecedentedly popular, and it has been confirmed that the gut microbiota closely correlates with the occurrence and development of all kinds of benign and malignant diseases. In this article, the effects of the gut microbiota and its metabolites on the occurrence and development of endometrial cancer is reviewed, and its application in the prevention, diagnosis and treatment of endometrial cancer is explored.

Abstract
CXCR7, an alternative receptor for the inflammatory chemokine SDF-1, is involved in cell proliferation and migration. Recent studies have reported that CXCR7 also plays a role in adipose tissue. However, evidence regarding the role of CXCR7 and its ligands in adipocyte differentiation is limited. In this study, we aimed to elucidate changes in CXCR7 expression during adipocyte differentiation and the role of the SDF-1/CXCR7/CXCR4 axis in adipogenesis using recombinant SDF-1, the CXCR7 ligand CCX771, and small interfering RNAs. The results indicated that the levels of SDF-1 and its receptors, CXCR7 and CXCR4, decreased during the early stages of adipogenesis. Treatment with recombinant SDF-1 and CCX771 inhibited adipogenesis and lipid accumulation by inducing β-arrestin2, Wnt expression, and AKT phosphorylation and downregulating C/EBPα, PPARγ, and FABP4 expression. In contrast, knockdown of SDF-1 and CXCR7 in preadipocytes downregulated the β-arrestin2/Wnt and AKT pathway, leading to the induction of adipogenesis. Meanwhile, knockdown of CXCR4 had no significant effect. In mice, basal gene expression levels of SDF-1 and CXCR7 were higher in the stromal vascular fraction compared to mature adipocytes and were significantly upregulated by a high-fat diet. Our results provide new insights into the local role of the SDF-1-CXCR7 axis in adipocytes and offer additional benefits for the prevention of obesity-related metabolic disorders.

Abstract
BACKGROUND Vascular calcification is common and progressive in patients with chronic kidney disease. However, the risk factors associated with the progression of vascular calcification in patients receiving maintenance dialysis have not been fully elucidated. Here, we aimed to evaluate vascular calcification and identify the factors associated with its progression in patients receiving maintenance hemodialysis. METHODS This is a prospective longitudinal study that included 374 patients receiving maintenance hemodialysis. The participants received assessments of coronary artery calcification (CAC) and abdominal aortic calcification (AAC), as measured by computed tomography. After the baseline investigation, a 2 years follow-up was performed. We also detected the markers of endothelial injury [E-selectin and soluble intercellular adhesion molecule-1 (sICAM-1)]. Finally, the risk factors affecting the CAC and AAC progression were examined by multivariate logistic regression analysis. RESULTS Among 374 patients, the median [interquartile range (IQR)] age was 54.0 (40.0-62.0) years; 59.9% of patients were male. The median (IQR) follow-up time was 1.9 (1.8-2.0) years for all patients. By the end of 2-year follow-up, progression of vascular calcification (including CAC and AAC) was observed in 58.0% of patients. Further, compared with the patients without progression of vascular calcification, the endothelial injury (including E-selectin and sICAM-1) of patients with progression of vascular calcification was markedly enhanced. Moreover, after adjustment for the confounders, endothelial injury was a risk factor for the progression of vascular calcification. CONCLUSION The present study indicated that endothelial injury is one of the risk factors for the progression of vascular calcification in patients receiving maintenance hemodialysis.

Decision model to evaluate the cost of clinical events associated with switching from apixaban to rivaroxaban among patients with non-valvular atrial fibrillation in the United States and Germany. J Med Econ 2025; 28:224-234.

Abstract
AIMS Direct-acting oral anticoagulants (DOACs) have emerged as the preferred treatment for nonvalvular atrial fibrillation (NVAF). However, evidence concerning the economic outcomes of DOAC switching remains limited. This study aimed to assess the economic outcomes of DOAC switching in the US and Germany, two countries with a high AF prevalence and DOAC utilization. METHODS A decision model was developed to assess the incidence and cost of stroke/systemic embolism (SE) and major bleeding (MB) associated with switching from apixaban to rivaroxaban in patients with NVAF. The model compared two scenarios: continuers (patients continuing apixaban) and switchers (patients switching from apixaban to rivaroxaban). Model inputs on clinical event rates were sourced from a published real-world study, cost inputs were from a standard costing database and published literature. The analysis was conducted over a 1-year time horizon from US Medicare fee-for-service and German public healthcare payer perspectives. RESULTS Over one year, 47,036 patients among a hypothetical plan size of 1,000,000 US Medicare fee-for-service members and 1,019,079 patients among the German adult population size of 70,107,122 were estimated to be treated for NVAF with apixaban. Switching all patients from apixaban to rivaroxaban resulted in 1,498 and 32,447 additional clinical events (stroke/SE and MB) and deaths in the US and Germany, respectively, compared to continuing with apixaban. This led to a total incremental cost of $17.3 million and €153 million from Medicare fee-for-service and German public healthcare perspectives, respectively. LIMITATIONS The incidence and hazard ratios of clinical events informing this analysis were based on a US commercial and Medicare Advantage population and may not be generalizable to other populations. CONCLUSIONS Switching from apixaban to rivaroxaban was associated with increased clinical events, deaths, and higher medical care costs, potentially representing a less favorable strategy economically compared to continuing apixaban among patients with NVAF.

Abstract
CONTEXT Qing-Xin-Jie-Yu Granule (QXJYG) has shown promise in the treatment of myocardial infarction. However, the mechanism of action of QXJYG underlying its anti-inflammation remain unknown. OBJECTIVE The study aimed to evaluate the effectiveness and mechanism of QXJYG in a mouse model of myocardial infarction and hypoxia-induced H9C2 cells. MATERIALS AND METHODS Myocardial infarction was induced in mice via left anterior descending coronary artery ligation, and hypoxia-induced H9C2 cells was served as the in vitro model. The cardiac function was evaluated by echocardiography, while myocardial tissue pathology was examined using HE and Masson's trichrome staining. Changes in serum markers of cardiac injury were measured using ELISA kits. The levels of inflammatory cytokines in both the serum and cardiac tissue were quantified using the Bio-Plex Pro Mouse Chemokine assay, and hypoxia-induced inflammatory factors in H9C2 cells were assessed by RT-qPCR. Additionally, western blot analysis was conducted to evaluate the expression of proteins related to the MK2/TTP signaling pathway both in vivo and in vitro experiments. RESULTS QXJYG significantly enhanced cardiac function in mice with myocardial infarction, as evidenced by improved myocardial tissue structure, reduced collagen fiber deposition, and lowered serum levels of creatine kinase isoenzyme MB (CK-MB), cardiac Troponin T (cTnT), and brain Natriuretic Peptide (BNP). QXJYG may reduce the expression of inflammatory factors in both the heart and serum of myocardial infarction-induced mice and attenuate hypoxia-induced levels of inflammatory factors in cardiomyocytes by decreasing the ratio of p-MK2/MK2 and increasing the protein expression of TTP. DISCUSSION AND CONCLUSIONS QXJYG improved cardiac function and reduced injury, fibrosis, and inflammation after myocardial infarction, likely through modulation of the MK2/TTP signaling pathway.

Abstract
OBJECTIVE To investigate the correlation between idiopathic neonatal hyperbilirubinemia and ductus venosus closure time and to examine prenatal factors influencing DV closure in neonates. METHODS A total of 103 full-term hyperbilirubinemic neonates born between September 2022 and September 2023 were selected as the hyperbilirubinemia group, while 169 full-term healthy neonates were chosen as the control group. Neonates with other perinatal or maternal abnormalities were excluded. Ultrasonographic examinations monitored ductus venosus closure time. ductus venosus blood flow, umbilical vein blood flow, ductus venosus shunt fraction, middle cerebral artery pulsitility index, and estimated fetal weight at term were retrospectively analyzed to compare differences between the two groups. The correlation between neonatal serum total bilirubin and ductus venosus closure time, as well as prenatal influences on ductus venosus closure time in neonates, were evaluated. RESULTS The hyperbilirubinemia group had significantly longer ductus venosus closure time than the control group (p < 0.05). A positive association was found between ductus venosus closure and elevated neonatal serum total bilirubin. Prenatal factors influencing ductus venosus closure time included ductus venosus shunt fraction and fetal weight, where lower fetal weight and higher ductus venosus shunt fraction were associated with a delayed ductus venosus closure in neonates. CONCLUSION Ductus venosus closure time is positively correlated with idiopathic neonatal hyperbilirubinemia, suggesting a potential role in its development. Fetal weight and the ductus venosus shunt fraction during the fetal period appear to influence the timing of ductus venosus closure in neonates.

Abstract
Skin ageing is a complex physiological process primarily characterised by the deepening of wrinkles and the sagging of the skin. Collagen is essential for maintaining skin elasticity and firmness. As skin ages, it experiences structural and functional changes in collagen, including a decrease in collagen synthesis and an increase in collagen hydrolysis. Thus, promoting collagen synthesis represents a practical strategy for mitigating skin ageing. This review systematically described the functions, classifications and biosynthesis process of collagen, as well as its role in skin ageing. Additionally, the major signalling pathways and targets associated with collagen synthesis were also discussed. More importantly, the review provided a detailed summary of natural products with collagen synthesis-promoting effects and highlighted small molecule compounds with potential anti-ageing activity, especially PPARδ agonists. The relevant content offers potential targets and lead compounds for the development of anti-skin ageing therapies.

Abstract
OBJECTIVE Caveolae are closely linked to the onset and progression of atherosclerosis. The pivotal involvement of caveolin-1 (CAV1) within the caveolae in atherosclerosis development has been consistently supported. However, the potential contributions of additional caveolae proteins to atherosclerosis necessitate further exploration. Therefore, this research aimed to afford clinical evidence linking CAVIN-2 to diabetic peripheral artery disease (PAD) and its role in low-density lipoprotein (LDL) transcytosis. METHODS Blood samples were collected from a total of 115 participants, including 36 patients without diabetes (ND), 26 patients with type 2 diabetes mellitus (T2DM), and 53 patients with T2DM and PAD (DM-PAD). The plasma levels of CAV1, CAVIN-1, and CAVIN-2 were measured by ELISA. The correlation between CAV1, CAVIN-1, CAVIN-2, and diabetic PAD was examined using Spearman correlation analysis. The predictive effect of CAV1 and CAVIN-2 were analyzed by receiver operating characteristic (ROC) curves. Cellular experiments were used to investigate the effect and mechanism of CAVIN-2 on LDL transcytosis. RESULTS Elevated CAV1 and CAVIN-2 levels were observed in T2DM and DM-PAD groups, with a positive correlation to DM-PAD and PAD severity. Both CAV1 and CAVIN-2 emerged as predictors of DM-PAD. In vitro, CAVIN-2 knockdown decreased LDL transcytosis, while CAVIN-2 overexpression increased it. Additionally, CAVIN-2 was found to inhibit eNOS activation and nitric oxide (NO) production, thereby promoting LDL transcytosis and atherosclerosis progression. CONCLUSION CAVIN-2 was positively correlated with DM-PAD and promoted LDL transcytosis through the inhibition of eNOS activation, contributing to atherosclerosis development. This study provided clinical evidence linking CAVIN-2 to diabetic PAD and suggested its potential as a biomarker for disease progression.

Holm H, Jujic A, Nilsson PM, Magnusson M, Malan L. The prognostic significance of stress-phenotyping for stroke incidence: the Malmö Diet and Cancer Study. Stress 2025; 28:2443980. [PMID: 39731532 DOI: 10.1080/10253890.2024.2443980] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2024] [Accepted: 12/08/2024] [Indexed: 12/30/2024] Open
Abstract
BACKGROUND Self-reported mental stress is not consistently recognized as a risk factor for stroke. This prompted development of a novel algorithm for stress-phenotype indices to quantify chronic stress prevalence in relation to a modified stroke risk score in a South African cohort. The algorithm is based on biomarkers adrenocorticotrophic hormone, high-density lipoprotein cholesterol, high-sensitive cardiac-troponin-T, and diastolic blood pressure which exemplifies the stress-ischemic-phenotype index. Further modification of the stroke risk score to accommodate alcohol misuse established the stress-diabetes-phenotype index. Whether positive stress-phenotype individuals will demonstrate a higher incidence of stroke in an independent Swedish cohort was unknown and investigated. METHODS Stress-phenotyping was done at baseline for 50 participants with incident stroke and 100 age-, and sex matched controls (aged 76 ± 5 years) from 2,924 individuals in southern Sweden. The mean time from inclusion to first stroke event was 5 ± 3 years. Stress-phenotyping comparisons and stroke incidence risk were determined. RESULTS A positive stress-ischemic-phenotype reflected higher incident stroke (72% vs. 28%, p = 0.019) and mortality rates (41% vs. 23%, p = 0.019). Whereas a positive stress-diabetes-phenotype reflected a higher incident stroke rate (80% vs. 20%, p = 0.008) but similar mortality rate (38% vs. 25%, p = 0.146). Both the positive stress-ischemic (OR: 2.9, 95% CI: 1.3-6.5, p = 0.011) and stress-diabetes-phenotypes (OR: 3.7, 95% CI: 1.5-8.9, p = 0.004) showed large effect size associations with incident stroke independent of cardiovascular risk confounders. CONCLUSION Positive stress-phenotype indices demonstrated a higher incidence of stroke. Ultimately the Malan stress-phenotype algorithms developed in South Africa could confirm incident stroke in an independent Swedish cohort. Stress-phenotyping could thus be useful in clinical routine practice in order to detect individuals at higher stroke risk.

Virulence 2025; 16:2489751. [PMID: 40189910 PMCID: PMC11980456 DOI: 10.1080/21505594.2025.2489751] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2024] [Revised: 02/04/2025] [Accepted: 04/01/2025] [Indexed: 04/11/2025] Open
Abstract
Severe dengue often presents as shock syndrome with enhanced vascular permeability and plasma leakage into tissue spaces. In vitro studies have documented the role of Src family kinases (SFKs) and RhoA-kinases (ROCK) in dengue virus serotype 2 (DENV2)-induced endothelial permeability. Here, we show that the FDA-approved SFK inhibitors Bosutinib, Vandetanib and Ponatinib, as well as the ROCK inhibitors, Netarsudil and Ripasudil significantly inhibit DENV2-induced endothelial permeability. In cultured telomerase immortalized human microvascular endothelial cells (HMEC-1), treatment with these inhibitors reduced the phosphorylation of VE-Cadherin, Src and myosin light chain 2 (MLC2) proteins that were upregulated during DENV2 infection. It also prevented the loss of VE-Cadherin from the inter-endothelial cell junctions induced by viral infection. In in-vivo studies using DENV2-infected AG129 IFN receptor-α/β/γ deficient mice, ponatinib, when administered 24 h post-infection onwards, demonstrated significant benefits in improving body weight, clinical outcomes, and survival rates. While all virus-infected, untreated mice died by day-10 post-infection, 80% of the ponatinib-treated mice survived, and approximately 60% were still alive at the end of the 15-day observation period. The treatment also significantly reduced disease severity factors such as vascular leakage, thrombocytopenia; mRNA transcript levels of proinflammatory cytokines such as IL-1β and TNF-α; and restored liver function. Comparable effects were observed even when ponatinib treatment was initiated after symptom onset. The results highlight ponatinib as an effective therapeutic option in severe dengue; and also a similar potential for other FDA- approved SFK and ROCK inhibitors.

Abstract
The efficacy of antibacterial therapy was largely vitiated because of the shield of bacteria by the intricate architecture of biofilms. For emerging phototherapy strategies like photothermal therapy (PTT) and photodynamic therapy (PDT), dense biofilms can substantially impede the permeation of photo-agents, ultimately compromising the thermal conductivity and reactive oxygen species (ROS) diffusion. To address these challenges, we have proposed a biofilm-sensitive MT nanorod with dual phototherapy, based on the ordered directional assembly of photosensitizer meso-tetra(4-carboxyphenyl) porphine (TCPP) molecules by metformin hydrochloride (MET) as functional backbone. The formed MT nanorod avoids the uncontrollable aggregation of TCPP, producing pleased water-solubility with efficient fluorescent emission and allowing simultaneous PTT-PDT effects under a single laser. The grafted MT-LYZ by conjugation of lysozyme (LYZ) to MT nanorods can be used for acidic environment guided deep biofilm penetration and LYZ-assisted dual phototherapy for effective elimination of mature biofilm, with MT-LYZ acquires adaptive conversion from negative to positive charges in biofilm. Because of effective bacterial ablation within biofilms and gene regulation in bacterial quorum, MT-LYZ was successfully utilized for the treatment of deep-seated MRSA biofilm infections with minimized side effects, which promotes the repair of the MRSA biofilm infected wounds in mice and displays anti-inflammatory features, providing an alternative approach for effectively combating biofilm infections.

Abstract
Acute pancreatitis (AP) is a common gastrointestinal disorder, and acute kidney injury (AKI) is a frequent and severe complication, significantly increasing mortality risk. Mean arterial pressure (MAP) is crucial for maintaining organ perfusion in critically ill patients. However, the optimal MAP target for minimizing mortality in AP patients complicated by AKI (AP-AKI) remains unclear. This retrospective cohort study analyzed data from the MIMIC-IV database, including 934 critically ill adult patients diagnosed with AP-AKI between 2008 and 2019. We investigated the relationship between MAP and in-hospital mortality using logistic regression models, adjusting for demographics, comorbidities, disease severity scores and intensive care interventions. Smooth curve fitting was used to explore potential non-linear associations. Subgroup analyses were performed to assess the impact of MAP across different clinical and demographic groups. Our analysis revealed a non-linear, L-shaped relationship between MAP and in-hospital mortality, with an inflection point at 71.32 mmHg. Below this threshold, increasing MAP was associated with significantly decreased odds of mortality (OR: 0.93, 95% CI: 0.87-0.99, p = 0.026). However, above this threshold, the association was no longer significant (OR: 1.015, 95% CI: 0.98-1.03, p = 0.699). Subgroup analyses showed consistent trends across most subgroups, with the benefit of maintaining MAP above the threshold being most pronounced in AKI stage 1 and 2 patients. This study suggests a potential association between maintaining specific MAP levels, particularly above 71.32 mmHg, and reduced in-hospital mortality in critically ill AP-AKI patients.

Abstract
OBJECTIVES The adipocyte-derived hormone leptin has been associated with the pathogenesis of cardiovascular disease. The mechanisms underlying this association are unclear but may relate to effects on the vascular endothelium. Our aim was to explore the effects of leptin on endothelial vasomotor and fibrinolytic function in healthy volunteers and patients with coronary artery disease. DESIGN The vascular effects of leptin were assessed infusing recombinant human leptin in healthy volunteers during measuring vasomotor response by venous occlusion plethysmography. Additionally, circulating levels of leptin were analysed in relation to endothelial dysfunction in patients with established coronary artery disease. RESULTS In healthy male volunteers, intra-arterial infusion of recombinant human leptin (80, 800 and 8,000 ng/min; n = 10) did not affect basal forearm blood flow, plasma tissue plasminogen activator (tPA) or plasminogen activator inhibitor type 1 concentrations (all p > 0.05). However, during concomitant co-infusion with leptin (800 ng/min; n = 10), drug-induced vasodilatation was reduced (p = 0.001), and tPA activity increased (p = 0.002). In patients with coronary artery disease, those with the high plasma leptin levels had reduced drug-induced vasodilatation (p < 0.001), and increased net release of tPA antigen and activity (p < 0.001 and p = 0.03, respectively) compared to those with low levels. The study has been registered retrospectively at Clinical Trials with number NCT04374500. CONCLUSION Intrabrachial leptin infusion did not affect the basal vascular tone, whereas acute and chronic hyperleptinemia was associated with blunted vasoreactivity in healthy volunteers, and in patients with coronary artery disease.

Abstract
Uric acid (UA), the final product of purine metabolism in humans, exhibits a dual role as an anti or pro-oxidant, depending on the microenvironment. The two-electron oxidation of UA by biological oxidants can neutralize such harmful molecules. Additionally, UA chelates metals and can activate adaptive response against oxidation. However, some products of the reaction between UA and oxidants are not inert and, therefore, do not confer the anticipated antioxidant protection. A direct pro-oxidant effect is favoured in the one-electron oxidation of UA by heme-peroxidases yielding free radical intermediates that can initiate or propagate a radical-chain reaction. Additionally, an indirect pro-oxidant effect has been proposed by eliciting the expression or activation of enzymes that catalyse oxidant production, e.g. NADPH oxidase (NOX). This review brings together fundamental concepts and the molecular mechanisms of the redox reactions involving UA. The signature metabolites from these reactions are discussed to give valuable insights on whether these intermediates are being formed and what role they may play in disease pathogenesis. It proposes that, through identifying specific products, it may be possible to elucidate whether a harmful or protective action is linked to downstream bioactivities.
