Volatile fatty acids (VFAs) provide more than 70% of the energy source for the ruminants. Understanding the host-microbiota regulation of VFAs production and utilization is highly important for optimizing the feed energy utilization efficiency of ruminants. Here, we conducted whole-genome resequencing, rumen transcriptome sequencing, 16S rRNA gene amplicon sequencing, and VFA concentration determination in 530 Holstein bulls. We treated VFA concentrations as complex traits to perform multi-omics association analyses. The host genetics, rumen microbiota, and rumen expressed genes, on average, explained 23%, 58%, and 61% of the variations in VFAs with the same diet, respectively. We found that the rumen microbial composition and community structure differed significantly between the high and low VFA individuals. We further identified 11 microbes with potential causal relationships with rumen VFAs via the Mendelian randomization method, among which Bacteroidales_RF16_group, Prevotella, Clostridia_UCG-014, and [Eubacterium]_ventriosum_group were positively correlated with acetic acid, propionic acid, and butyric acid. Conversely, rumen epithelial genes involved in fatty acid β-oxidation (e.g., HSD17B4, ACADVL, ACADL, CPT1A, and ANGPTL4) were negatively correlated with the main VFAs and VFA-producing bacteria. These candidate microbes and genes suggest that the host-microbe coregulating mechanism facilitates the efficient production and utilization of rumen VFAs in ruminants. Our study provides a comprehensive perspective on the complex dynamic regulatory patterns of rumen VFAs, highlighting the crucial role of host-microbe interactions in optimizing the feed utilization of ruminants.

Atherosclerotic plaque instability is a direct cause of cardiovascular and cerebrovascular events. In this study, a mitochondria-targeted liposome (LIP), modified with triphenylphosphonium (TPP) to enable specific mitochondrial delivery, was innovatively constructed to encapsulate a PCSK9 inhibitor (TPP-LIP@PCSK9). The aim was to explore a novel strategy for stabilizing plaques by restoring mitochondrial function in endothelial cells. Characterization results showed that TPP-LIP@PCSK9 possesses favorable nano-characteristics, and its targeting capability was confirmed through mitochondrial co-localization experiments.

Endometrial carcinoma (EC) is a common malignancy of the female reproductive system. Rab35 is widely recognized as an oncogenic driver and has been implicated in the progression of various malignant tumors. However, its regulatory mechanism and pathobiological roles in EC remain unclear. Rab35 expression in EC was systematically profiled via integrative analysis of clinical endometrial specimens and multi-omics databases (CPTAC and GEO). The association between clinical prognosis and Rab35 expression was examined using Kaplan-Meier analysis. Mechanistic investigations included transwell assays, western blotting, and immunofluorescence in Rab35-overexpressing and CRISPR/Cas9-mediated Rab35-knockout EC cells. A mouse xenograft tumor model was established to confirm the effects of Rab35 in vivo. The Rab35 content increased gradually from normal endometrium to atypical hyperplastic endometrium to EC. Moreover, the findings indicated that elevated Rab35 expression was significantly associated with advanced disease characteristics and poor overall survival in patients with EC. In addition, Rab35 enhanced the migratory and invasive nature of EC cells. The expression of Rab35 was inversely linked to that of the β-catenin destruction complex-related proteins Axin-1 and GSK3β, leading to the increased nuclear translocation of β-catenin in EC cells. Animal experiments further verified that Rab35 augmented EC progression by regulating the nuclear translocation of β-catenin. The study revealed that high expression of Rab35 was strongly correlated with EC progression and a poor clinical outcome. Furthermore, Rab35 promoted EC cell metastasis by accelerating the nuclear translocation of β-catenin. These findings suggest that Rab35 serves as a valuable biomarker and therapeutic target for EC.

Conversion of cholesterol into bile acids is a central pathway for cholesterol disposal, which was mainly controlled by cholesterol 7alpha-hydroxylase (Cyp7a1). In present study, we aimed to investigate the effect and the potential underlying mechanism of microRNA-96 (miR-96) on atherosclerosis development. The anti-atherosclerosis effects of a miR-96 inhibitor (miR-96i) were evaluated using ApoE KO mice fed a high-fat diet, which was treated with miR-96i for 8 weeks. The regulatory mechanism was revealed and validated by RNA-seq transcriptomics, quantitative PCR and western blotting analyses in hepatic cells. The authors identified that miR-96i significantly decreased serum cholesterol and bile acid levels and attenuated arterial plaque in mice. We further revealed that miR-96 regulated Cyp7a1 via a FOXO1-involved indirect pathway, in which miR-96 directly modulated FOXO1 in a posttranscriptional manner. A coordinated regulatory effect of miR-96 and miR-185 on FOXO1 was also observed. The full spectrum of mechanisms underlying the antiatherosclerotic activity beside miR-96-FOXO1-CYP7A1 axis remains to be elucidated. This study provides convincing evidence for the pivotal role of miR-96 in FOXO1 modulation and CYP7A1-involved cholesterol-bile acid metabolism, suggesting that miR-96 is a novel therapeutic target for the discovery and development of drugs against ACVD.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a prevalent inflammatory disorder characterized by nasal obstruction and polyp formation. Despite its prevalence, the complex pathogenesis of CRSwNP remains not fully understood, hindering the development of effective treatments. This study aims to delineate the immunological landscape of CRSwNP by integrating single-cell RNA sequencing (scRNA-seq) and Mendelian randomization (MR) approaches. We conducted a systematic MR analysis using summary statistics from genome-wide association studies (GWAS) and expression quantitative trait loci (eQTL) data. The identified genes were further scrutinized through scRNA-seq analysis of CRSwNP tissues to assess cell-specific expression patterns. Pathway enrichment and protein-protein interaction (PPI) network analyses were performed to explore the biological mechanisms underlying CRSwNP. The MR analysis identified several genes, including HLA-DRB1, HLA-DQA1, and HLA-DQB1, as significantly associated with CRSwNP. The scRNA-seq analysis validated these findings, revealing cell-specific enrichment in basal cells. Notably, these genes were found to be involved in immune cell recruitment and the reshaping of the immune microenvironment. Furthermore, the study highlighted the role of genes like TCF7L1, KANSL1-AS1, and POLR2J3, which showed contrasting expression patterns and potential regulatory roles in CRSwNP. This integrative study provides novel insights into the molecular and cellular underpinnings of CRSwNP. The identified genes and their role in immunopathogenesis offer potential therapeutic targets and highlight the importance of cell-specific gene expression in disease mechanisms. The combination of MR with scRNA-seq represents a powerful approach to elucidate complex traits and may pave the way for precision medicine in CRSwNP management. Show less

Alport syndrome (AS) is the most common inherited glomerular disease among patients with chronic kidney disease. With exome sequencing now widely used in clinical practice, pathogenic variants in Alport-related genes (COL4A3/COL4A4/COL4A5) are increasingly identified in patients with diverse phenotypes, including proteinuria‑predominant disease and kidney failure of unknown etiology. Diagnostic complexity further increases when COL4A3/COL4A4/COL4A5 variants are co‑inherited with pathogenic variants associated with other genetic kidney disorders. We reported a 31‑year‑old male presenting with kidney failure, significant proteinuria, familial hematuria and hyperlipidemia. Whole‑exome sequencing (WES) identified two pathogenic variants: a hemizygous COL4A5 variant (c.2105G > A; p.Gly702Asp) and a heterozygous APOE Kyoto variant (c.127C > T; p.Arg43Cys). Given the potential dual diagnosis of AS and lipoprotein glomerulopathy (LPG), a kidney biopsy was performed. Histologic examination revealed uneven thickness of the glomerular basement membrane consistent with the diagnosis of AS, but no LPG-related lesions were observed, indicating incomplete penetrance of APOE Kyoto variant. Cascade family screening detected APOE Kyoto variant in the patient's father and elder sister, both of whom lacked proteinuria until follow-up period. This case highlights the complementary role of kidney biopsy alongside WES in AS with complex genetic mechanisms. It also illustrates the incomplete penetrance of APOE Kyoto, common among Chinese carriers. Show less

C-reactive protein (CRP) is a liver-derived soluble marker of inflammation whose levels can predict the risk of atherosclerotic cardiovascular disease and therapeutic efficacy of statins. Intriguingly, however, CRP is not considered as a mediator of atherosclerosis based primarily on studies examining chow diet (CD)-fed mice. The aim of this study is to investigate the role of CRP in high-fat diet (HFD)-induced atherosclerosis, which models a more prevalent scenario in the real world, and to clarify its impact on Atorvastatin treatment. Apoe-sufficient or -deficient mice with or without Crp knockout were fed with CD, HFD, or methionine- and choline-deficient diet, or subjected to carotid artery ligation or Atorvastatin treatment. Hepatic, vascular, and metabolic indexes were then analyzed. The effects of CRP on lipid droplet formation were examined by cellular assays. Knockout of Crp in Apoe-deficient mice does not affect the progression of atherosclerosis under CD feeding, but significantly reduces plaque burden under HFD feeding. The pro-atherosclerotic effects of Crp are not due to direct modulation of vascular inflammation, but appear to be the result of enhanced lipid accumulation in the liver and the ensuing aggravation of hyperlipidemia. Mechanistically, Crp enhances hepatic lipid accumulation by upregulating Cidea to promote the formation of enlarged lipid droplets in hepatocytes. We further show that the therapeutic efficacy of Atorvastatin on HFD-induced atherosclerosis in Apoe-deficient mice is largely dependent on Crp. Our findings identify a previously unrecognized role of CRP in enhancing hepatic lipid accumulation under stresses induced by dietary or genetic factors, which underlies its secondary impact on atherosclerosis and determines the therapeutic efficacy of Atorvastatin.

An 8-week experiment was conducted to evaluate the effects of dietary phosphatidylserine (PS) supplementation on juvenile large yellow croaker (Larimichthys crocea) fed high soybean oil (SO) diets. A fish oil control, an SO control, and four SO-based diets supplemented with 0.002%, 0.006%, 0.018%, or 0.054% PS were formulated. Results showed that weight gain exhibited quadratic responses to increasing PS levels. PS supplementation alleviated hepatic lipid deposition and reduced serum and hepatic lipid concentrations. At the molecular level, PS downregulated hepatic lipogenic gene expression including sterol regulatory element-binding protein 1 (srebp1), fatty acid synthase (fas), stearoyl-CoA desaturase 1 (scd1), and acetyl-CoA carboxylase 1 (acc1). Conversely, it upregulated hepatic lipid catabolism genes: peroxisome proliferator-activated receptor a (ppara), lipoprotein lipase (lpl), carnitine palmitoyltransferase 1 (cpt1), and diacylglycerol O-acyltransferase 1 (dgat1). Additionally, PS restored antioxidant enzyme activities and the expression of superoxide dismutase (sod1, sod3), glutathione peroxidase (gpx), and catalase (cat) in the liver. Furthermore, PS reduced hepatic pro-inflammatory cytokine mRNA levels: tumor necrosis factor α(tnf-α), cyclooxygenase 2 (cox-2), and interleukins (il-6, il-1β). In conclusion, dietary inclusion of 0.006%-0.018% PS effectively enhanced growth and antioxidant capacity, modulated lipid metabolism, and influenced inflammatory responses. Show less

Coronary restenosis remains a major challenge following percutaneous coronary intervention (PCI), necessitating the development of effective stent-eluting drugs. Previous studies indicate that scutellarin protects vascular endothelial cells and exhibits anti-thrombotic and anti-platelet effects. Notably, our prior research demonstrated that scutellarin specifically counteracts oxidative stress-driven endothelial dysfunction, a key initiating event in restenosis. This combined evidence strongly suggests its potential against in-stent restenosis (ISR). Therefore, this study explores the efficacy of scutellarin in preventing ISR after PCI. We investigated scutellarin, derived from Erigeron breviscapus, for its potential to prevent ISR following PCI. The efficacy and mechanism of scutellarin were evaluated using both in vivo and in vitro models. An experimental atherosclerosis model was established in APOE In APOE This study establishes the efficacy of scutellarin in mitigating ISR using two complementary in vivo models. Scutellarin-eluting stents in atherosclerotic minipigs overcome translational barriers through full interventional simulation. Furthermore, scutellarin inhibits VSMCs proliferation, migration and promotes autophagy-coordinated apoptosis by the coordinated downregulation of both the Pl3K/AKT and lKKs/NF-κB cascades.These findings highlight scutellarin as a promising candidate for next-generation bioactive stent coatings, bridging phytopharmacology and precision interventional cardiology.

The objective of our investigation was to explore the features of gut microbiota dysbiosis and the concentrations of gut metabolites in relation to white matter injury (WMI). Furthermore, we sought to evaluate the influence of gut dysbiosis on neuroinflammation in WMI via intestinal metabolites, and its contribution to pathogenesis. A cerebral hypoxia-ischemia-induced WMI model was established in 3-day-old Sprague-Dawley rats. Liquid chromatography-mass spectrometry/gas chromatography-mass spectrometry analyses and 16S rRNA gene sequencing were undertaken to ascertain WMI biomarkers. Mechanistic experiments were used to analyse activation of the H3K9ac/BDNF/TrkB pathway and neuroinflammation. The analysis of 16S rRNA sequencing disclosed gut microbiota dysbiosis in WMI rats, quantified using linear discriminant analysis effect size. Overall, 341 differentially expressed metabolic markers between the WMI and Sham groups were discovered. The Kyoto Encyclopedia of Genes and Genomes network enhancement evaluation revealed significant downregulation of 20 metabolic processes in the WMI group, which is strongly related to changes in fecal microbial metabolites, and the synthesis process of unsaturated fatty acids was the most significant. Gut microbiota dysbiosis may influence WMI by downregulating metabolites such as eicosapentaenoic acid (EPA). Fecal microbiota transplantation increased EPA concentration in the brain tissue of WMI rats. Gut microbiota-derived EPA promoted H3K9ac and BDNF/TrkB expression and inhibited the transcription of pro-inflammatory TNF- WMI induces gut dysbiosis involving down-regulation of unsaturated fatty acid synthesis. Fecal microbiota transplantation leads to increased levels of EPA. Gut microbiota-derived EPA increases levels of acetylated histone H3K9ac, causes activation of the BDNF/TrkB pathway, reduces neuroinflammation, and improves WMI-associated myelination disorders. It provides a basis for targeted treatment of white matter injury in the future. Show less

AllergoOncology has emerged as an interdisciplinary field exploring the interaction between allergic diseases and cancer; however, the lack of stable in vivo models has limited mechanistic investigations. This study aimed to establish an experimental animal model to explore the impact of systemic allergic responses on tumor progression and to provide preliminary insights into the regulatory role of allergy in cancer development. An ovalbumin (OVA)-induced systemic allergy tumor-bearing mouse model (OVA-TM) was established by OVA sensitization followed by subcutaneous implantation of CT26 colon cancer cells. Tumor growth, immune responses, and behavioral changes were systematically evaluated. Tumor immune microenvironment alterations were assessed using immunological and histological analyses. Transcriptomic profiling and mass spectrometry imaging (MSI) were integrated to investigate immune-related metabolic alterations. Human tumor survival datasets were used to validate the prognostic relevance of differentially expressed genes (DEGs), and enrichment analyses of allergy- and cancer-associated genes were performed using humanized databases. OVA-induced systemic allergy significantly suppressed tumor growth and promoted immune cell infiltration, particularly CD3 This study establishes a practical in vivo model for AllergoOncology and demonstrates that systemic allergic responses can modulate tumor progression through immune activation, apoptosis, and inflammation-metabolism axis reprogramming, providing a foundation for future mechanistic and therapeutic studies.

This study aims to evaluate the association between multiple lipid indices and coronary collateral circulation (CCC) in patients diagnosed with acute ST-segment elevation myocardial infarction (STEMI). This was a cross-sectional retrospective study involving 421 patients with STEMI who underwent coronary angiography between January 2022 and December 2024. Participants were categorized into a poor CCC group (Rentrop grade 0-1) and a good CCC group (Rentrop grade 2-3) according to Rentrop grading criteria. The following lipid parameters were evaluated as both continuous and categorical variables: total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), lipoprotein(a) [Lp(a)], apolipoprotein B (ApoB), apolipoprotein A-I (ApoA-I), non-HDL-C/HDL-C, ApoB/ApoA-I, atherogenic index of plasma (AIP), and lipoprotein composite index (LCI). The associations between these lipid indices and CCC status were assessed using multivariate logistic regression and receiver operating characteristic (ROC) curve analysis. Multivariate logistic regression analysis revealed that higher HDL-C quartiles were significantly associated with reduced odds of poor CCC (odds ratio [OR]: 0.544, 95% confidence interval [CI]: 0.351-0.771, P < 0.05), whereas elevated LDL-C (OR: 29.299, 95% CI: 3.562-240.976, P < 0.05), non-HDL-C (OR: 50.140, 95% CI: 5.408-464.834, P < 0.01), and non-HDL-C/HDL-C (OR: 4.510, 95% CI: 1.186-25.368, P < 0.05) quartiles were significantly associated with increased odds of poor CCC. Receiver operating characteristic (ROC) curve analysis demonstrated that LDL-C (cutoff: 3.265, AUC: 0.647, 95% CI: 0.573-0.721, P < 0.001), non-HDL-C (cutoff: 2.735, AUC: 0.752, 95% CI: 0.688-0.816, P < 0.001), and non-HDL-C/HDL-C (cutoff: 2.393, AUC: 0.686, 95% CI: 0.611-0.761, P < 0.001) exhibited favorable predictive performance for poor CCC. Stratification analysis showed that the highest prevalence of poor CCC was observed in patients with concurrently elevated levels of LDL-C, non-HDL-C, and non-HDL-C/HDL-C. Several lipid indices-including LDL-C, non-HDL-C, and the non-HDL-C/HDL-C ratio-are significantly associated with impaired CCC in patients with STEMI. Notably, non-HDL-C exhibits the strongest association with CCC dyscrasia and therefore warrants early clinical attention. Show less

Chronic pain, marked by nociceptive sensitization and maladaptive neuroplasticity, affects 30% of the global population with escalating socioeconomic burdens. Epidemiological data show a 2-3-fold increase in neuropsychiatric co-morbidities among individuals with chronic pain, where epigenetic dysregulation serves as a key mechanism linking ongoing pain to emotional disorders. This review systematically explores epigenetic signatures in supraspinal integration hubs, notably the limbic-paralimbic networks and prefrontal regulatory circuits. The identified epigenetic signatures encompass dysregulation of DNA methyltransferases (DNMTs), RNA modifications, histone post-translational modifications and locus-specific alterations, including aberrant methylation at the brain-derived neurotrophic factor (BDNF), opioid μ receptor and transient receptor potential ankyrin 1 (TRPA1) gene loci. Additionally, they involve dysfunction of the glucocorticoid receptor (GR)/corticotropin-releasing factor (CRF) axis via epigenetic modulation. Building on these findings, we evaluate therapeutic strategies addressing epigenetic dysregulation. While preclinical data demonstrate the efficacy of histone deacetylase (HDAC) and DNMT inhibitors, clinical translation faces significant barriers, including limited blood-brain barrier permeability. Notably, our analysis highlights the benefits of combining pharmacological interventions with non-invasive neuromodulation for enhanced co-morbidity management. Looking forward, this review proposes innovative approaches that leverage CRISPR-based chromatin editing platforms, biomimetic nanocarriers for neuron-specific delivery and closed-loop neuromodulation integrating real-time biomarker feedback, collectively establishing a precision medicine framework for pain or neuropsychiatric co-morbidities.

DUSP6, a dual-specificity phosphatase, has become a focal point in understanding the pathogenesis of various liver disorders. This study aims to investigate the role of DUSP6 in liver fibrosis and explore the underlying mechanism. Using a CCL4-induced mouse model, the consistent upregulation of DUSP6 expression was observed. Notably, when Dusp6 was knocked down, liver fibrosis showed significant improvement, revealing a protective effect intricately linked to the ERK pathway. This was accompanied by an increase in ferroptosis-related proteins SLC7A11 and GPX4, underscoring the role of ferroptosis, an iron-dependent form of regulated cell death, in this process. Transcriptomic analysis further revealed a crucial downregulation of Cyp2e1 following Dusp6 knockdown. In vitro, DUSP6 knockdown not only promoted ERK phosphorylation but also suppressed CYP2E1 expression, enhancing cell proliferation, bolstering hepatocyte resistance to ferroptosis, and alleviating hepatocyte injury. Importantly, inhibiting CYP2E1 in mouse models of liver fibrosis effectively slowed the progression. These findings illuminate a critical regulatory mechanism that DUSP6 regulates liver fibrosis via targeting ferroptosis, offering new a direction for therapeutic strategies in liver disease.

Validate the clinical utility of exosome cargo (miRNAs/proteins) and NLRP3/BDNF as key regulatory molecules for acupuncture-mediated spinal cord injury (SCI) recovery. From the establishment of the database to May 2025, a literature search was conducted on PubMed, and Embase, using keywords ["exosome cargo" or "exosome"], ["acupuncture" or "acupuncture and moxibustion" or "electroacupuncture" or "EA"], ["spinal cord injury" or "SCI"], ["immune regulation"], ["inflammatory reaction"], ["neuroregeneration" or "nerve"]. Including peer-reviewed studies on human/animal models, articles that do not meet the requirements are excluded. Preclinically, MSC-exosomal miR-145-5p suppressed TLR4/NF-κB signaling, reducing spinal IL-1β by 47% in SD rats. Schwann cell-exosomal MFG-E8 activated SOCS3/STAT3, increasing M2 macrophage CD206 by 63% and raising rat BBB scores by 3.8 points; Treg-exosomal miR-2861 upregulated tight junction proteins (occludin/ZO-1) to repair the blood-spinal cord barrier. Acupuncture (EA at GV14/GV4) upregulated spinal BDNF by 72% and NGF by 58% via Wnt/β-catenin, while EA at GV6/GV9 downregulated NLRP3 by 42-58% and TNF-α by 35-47%. Clinically, EA at EX-B2 increased ASIA scores by 3.2±1.1 points (Guo et al). Besides, 5x/week EA improved ASIA vs 3x/week (+6.4 points). EA+exercise reduced MAS by 1.6-2.9 points, with outcomes correlated to peripheral NLRP3 reduction, BDNF elevation, and MBI/WISCIII increases. Exosome cargo (miR-145-5p/MFG-E8) and NLRP3/BDNF are key regulatory molecules underlying acupuncture-mediated SCI recovery. However, limitations (small RCT samples, heterogeneous acupuncture protocols, unstandardized exosome isolation) hinder translation. Future work should focus on standardized biomarker detection, exosome engineering, and large-scale clinical trials. Show less

Non-small cell lung cancer (NSCLC) is the most common type of lung cancer and the leading cause of cancer-related deaths. Immune checkpoint inhibitors (ICIs) of programmed death-1 (PD-1)/programmed death ligand-1 signaling induce tumor regression in some patients with NSCLC, but most patients with NSCLC exhibit resistance to ICIs therapy. NSCLC shapes the potent tumor immunosuppressive microenvironment (TIME) that underlies tumor immune tolerance and acquired resistance. Therefore, elucidating the cellular and molecular mechanisms by which NSCLC establishes and sustains the TIME is essential for developing novel strategies to overcome immune resistance and enhance the clinical benefit of ICIs. The correlation between sterile alpha motif domain and histidine-aspartate domain-containing protein 1 (SAMHD1) expression and ICIs was analyzed via immunohistochemistry. Cell migration assay was performed to assess the effect of SAMHD1 on macrophage recruitment. Multicolor flow cytometry was performed to analyze the effect of SAMHD1 knockdown on the tumor microenvironment. SAMHD1 regulation of the dual specificity phosphatase 6-extracellular regulated protein kinases 1/2 (DUSP6-ERK1/2) pathway was verified by RNA sequencing and western blotting. Here, we identify the SAMHD1 as a potential therapeutic target and a major determinant of poor response to ICIs in patients with NSCLC. Tumors with high SAMHD1 expression show resistance to anti-PD-1 antibody (αPD-1) treatment, whereas tumors with low SAMHD1 expression are highly sensitive. SAMHD1-dependent resistance to αPD-1 is characterized by increased tumor-associated macrophages (TAMs) infiltration and reduced CD8+T cell numbers. Mechanistically, SAMHD1 regulates the expression of macrophage-associated chemokines by influencing the activation of the DUSP6-ERK1/2 pathway, which contributes to TAMs aggregation within NSCLC tumors to shape an immunosuppressive microenvironment. The HIV accessory protein viral protein-x (VPX) specifically degrades SAMHD1 to promote HIV replication. Similarly, the vpx-engineered oncolytic adenovirus (oAd-vpx) targets SAMDH1 degradation to enhance oncolytic adenovirus replication and weaken the hostile immune microenvironment shaped by TAMs, thereby triggering a CD8+T-cell-dependent antitumor immune response. The combination of oAd-vpx and αPD-1 inhibits tumor growth and enhances sensitivity to ICIs in both mouse and human NSCLC. This research identifies a key mechanism of SAMHD1-driven immunosuppression and highlights its important role in oncolytic adenovirus therapy. This study provides a theoretical basis for targeting SAMHD1 as a drug therapy strategy in patients with NSCLC. Show less

Digital technology is frequently regarded as a tool to alleviate loneliness and enhance mental health among older adults, yet its effectiveness remains contested. This study explores whether digital exclusion moderates the association between loneliness and depressive, and examines symptom structure and depressive subtypes. Drawing on data form the 2018 and 2020 waves of the CHARLS (N = 13,719), we employed fixed-effect and mixed-effect models to assess the effect of loneliness on depressive and the moderating role of digital exclusion. Latent profile analysis (LPA) was used to identify symptoms subtypes, while symptom network analysis assessed centrality and network stability. Loneliness significantly predicted depressive symptoms across multiple models, demonstrating robust effects. Digital exclusion was positively associated with depressive symptoms but did not exhibit a statistically significant moderating effect on the loneliness-depression relationship (p > 0.05, Δβ ≈ 0.011). LPA identified six psychologically meaningful subtypes of depression. Symptom network analysis revealed that emotional and motivational symptoms occupied central positions within the network structure, whereas loneliness, despite its strong connections, exhibited relatively low centrality. The overall network structure remained stable over two years, with the digital access group exhibiting stronger network connectivity. This study emphasizes that digital access alone is not a universal remedy for alleviating loneliness. The psychological benefits of digital technology depend on the alignment between individual motivations, usage patterns, and broader social contexts. Future research should focus on digital usage quality and contextual adaptability of interventions, promoting a shift from customization in digital mental health intervention strategies. Show less

Facial nerve injury (FNI) is a common peripheral neuropathy that severely impairs facial function and quality of life. Qianzheng Powder (QZP) is a traditional Chinese herbal formula used to treat facial paralysis clinically, yet its neuroprotective mechanisms remain unclear. This study aims to evaluate the therapeutic effects of QZP on FNI and potential underlying mechanisms. A FNI model was established in male C57BL/6 mice by performing facial nerve crush surgery. QZP (3.51 g/kg) was administered orally once daily for 14 days post-surgery. Facial function was assessed behaviorally. Tissue samples were collected on day 21 for histological evaluation, qPCR and Western blotting. Liver and kidney safety were also assessed via H&E staining and serum biochemical markers. QZP significantly improved facial motor function from day 7 post-injury. Additionally, QZP treatment mitigated neuronal loss in the facial motor nucleus, attenuated buccinator muscle atrophy, and enhanced myelin regeneration, as evidenced by increased MPZ and MBP expression. These were consistent with the increace of the BDNF, TrkB, and QZP promotes structural and functional recovery of facial nerve following injury, likely through activation of the BDNF/TrkB/CREB axis, and demonstrates a favorable safety profile. These findings support its potential as a therapeutic adjunct in peripheral nerve repair. Show less

Arterial thrombectomy (AT) is a cornerstone in the treatment of acute ischemic stroke (AIS) due to large vessel occlusion. However, the optimal therapeutic time window and the best management strategy for patients presenting beyond the conventional 4.5-hour timeframe remain areas of active investigation and debate. This retrospective cohort study aimed to analyze the effect of timing of AT on recovery in AIS. We retrospectively analyzed 117 AIS patients admitted between January 2021 and January 2023. Participants were categorized into 3 groups: early AT (onset-to-AT < 4.5 hours), late AT (onset-to-AT ≥ 4.5 hours), and late AT + intravenous thrombolysis (IT). Outcomes compared included clinical efficacy, National Institutes of Health Stroke Scale (NIHSS) scores, serum levels of neurotrophic factors, brain-derived neurotrophic factor, vascular endothelial growth factor, residual stenosis, vessel reocclusion, 3-month mortality, and 1-month complications. The total effective rate was higher in the early AT and late AT + IT groups than in the late AT group. Pretreatment NIHSS scores and serum neurological marker levels were comparable across all groups. After treatment, the early AT and late AT + IT groups showed significantly lower NIHSS scores, higher serum levels of neurological markers, and improved treatment efficiency compared to the late AT group. Prognosis-related markers also indicated better outcomes in these 2 groups. Additionally, complications such as mucocutaneous ecchymosis, gastrointestinal bleeding, and intracranial bleeding were significantly reduced in the early AT and late AT + IT groups. AT within 4.5 hours of stroke onset improves efficacy, reduces neurological injury, and decreases complications. For patients presenting beyond 4.5 hours, combining AT with IT achieves comparable therapeutic benefits. Show less

ObjectiveTo evaluate the effects of a combined psychological and functional exercise intervention on emotion, quality of life, and brain-derived neurotrophic factor (BDNF) levels in patients with Parkinson's disease (PD).MethodsIn this randomized controlled trial, 172 patients with PD were randomly assigned into 2 groups with 86 patients in each group. The control group received routine care, while the intervention group received a 12-week intervention combining psychological support with functional exercise in addition to routine care. Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), Parkinson's Disease Questionnaire-39 (PDQ-39), Barthel Index, Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), and serum BDNF levels were assessed before and after the intervention. Adherence rates were also determined for each group. Spearman correlation analysis was used to examine associations between changes in BDNF (ΔBDNF) and changes in HAMA (ΔHAMA) and HAMD (ΔHAMD) scores.ResultsAt the end of the 12-week clinical trial, the intervention group demonstrated significantly lower HAMA, HAMD, PDQ-39, and MDS-UPDRS scores ( Show less

Aging-related cognitive decline is a major concern in aging societies. Theobromine (TB), a cacao-derived methylxanthine, exerts neuroprotective effects through anti-inflammatory, antioxidant, and neurotrophic mechanisms; however, its efficacy in aging models remains unclear. This study investigated the mechanisms underlying neuroprotective effects of chronic TB administration in senescence-accelerated mouse prone 8 (SAMP8), a model of age-related memory impairment. SAMP8 and SAMR1 mice were fed either a control diet or a diet supplemented with 0.05% TB for 50 d. Cognitive performance was evaluated by the novel object recognition (NOR) test. Neurotrophic factors (BDNF and NT-3), synaptic proteins (PSD95 and synaptophysin), and plasticity-related signaling molecules (phosphorylated CREB and TrkB) were analyzed in the prefrontal cortex and hippocampus. Inflammatory cytokines, lipid peroxides, and antioxidant enzymes were quantified. Molecular docking was used to assess TB's interaction with phosphodiesterase (PDE) enzymes. TB improved short-term memory in SAMP8, increasing discrimination index in the NOR test. This was accompanied by increased BDNF, NT-3, PSD95, and synaptophysin levels and enhanced CREB and TrkB phosphorylation. Furthermore, TB lowered the levels of pro-inflammatory cytokines (IL-1β, TNF-α) and phosphorylated NF-κB, reduced lipid peroxidation, and increased the levels of antioxidant markers (HO-1, GSH). These effects were minimal in SAMR1. No adverse effects on body weight or blood parameters were observed. Molecular docking indicated that TB binds to PDE enzymes with weaker inhibitory activity than selective inhibitors. TB enhances short-term memory and synaptic function in aged mice via neurotrophic, antioxidant, and anti-inflammatory mechanisms, supporting its potential as a safe dietary intervention for age-related cognitive decline.

Clinical application of mesenchymal stem cells for endometrial repair has been hampered by variability in cell quality, large-scale production, and uncertainty regarding the optimal delivery route. In this study, we investigated the therapeutic potential of clinical-grade human embryonic stem cell-derived immunity-and-matrix-regulatory cells (IMRCs) for treating refractory moderate-to-severe intrauterine adhesion (IUA). In a rabbit IUA model, sub-endometrial injection of IMRCs significantly reduced fibrosis and enhanced endometrial angiogenesis, outperforming uterine perfusion. Transcriptomic analysis revealed distinct pro-angiogenic gene expression profiles between the two delivery routes. In vitro, IMRCs co-cultured with endometrial stromal cells (ESCs) markedly enhanced angiogenic potential compared to either cell type alone. Protein array analysis of the co-culture supernatant showed elevated levels of angiogenic factors, with functional assays confirming that inhibition of ANGPTL4, a non-canonical pro-angiogenic mediator, impaired angiogenesis. In a first-in-human, single-center, phase 1 dose-escalation trial involving 18 patients with refractory IUA, high-dose sub-endometrial IMRC injection promoted angiogenesis, reduced uterine scarring, and improved pregnancy outcomes, with no safety concerns observed over 3 years of follow-up. These findings highlight the translational promise of IMRCs as a novel therapeutic strategy for endometrial regeneration in severe IUA. Show less

Neurodegenerative and psychiatric disorders share overlapping molecular mechanisms, including neuroinflammation, oxidative stress, and neurotransmitter dysregulation. Essential oils from Lavandula angustifolia (TLEO) and Rosa rugosa (PREO) contain neuroactive compounds with therapeutic potential, but their mechanisms remain poorly defined. This study aimed to elucidate the shared and distinct molecular targets and pathways of TLEO and PREO using a multi-scale computational strategy. Compounds identified by GC-MS were evaluated through ADMET profiling, target prediction, and disease-target intersection analysis. Enrichment, network, docking, and dynamics analyses were performed on shared protein-coding targets between essential oils and twelve brain disorders, including seven neurodegenerative conditions (Alzheimer's disease, amyotrophic lateral sclerosis, Friedreich ataxia, Huntington's disease, Lewy body disease, Parkinson's disease, spinal muscular atrophy) and five psychiatric disorders (autism spectrum disorder, attention deficit-hyperactivity disorder, bipolar disorder, major depressive disorder, and schizophrenia). A total of 110 compounds yielded 252 common targets, with CHRM2 (GPCR) and NR1H3 (non-GPCR) identified as key hubs. Docking suggested strong binding affinities for caryophyllene oxide at CHRM2 (-7.3 kcal/mol) and α-himachalene at NR1H3 (-8.5 kcal/mol). Molecular dynamics simulations confirmed stable, compact complexes with low RMSD and SASA values. MM/PBSA free energy calculations quantitatively validated these interactions, revealing favorable binding energetics driven predominantly by van der Waals and hydrophobic contributions, consistent with the terpenoid chemical profiles. Functional enrichment highlighted involvement in cholinergic signaling, lipid metabolism, and inflammatory regulation. This study demonstrates that PREO and TLEO can modulate multiple targets relevant to brain disorders through both GPCR and non-GPCR mechanisms. These findings provide a computationally inferred mechanistic framework for the potential neuroprotective synergy of these oils and highlight essential oil-derived compounds as promising leads for further experimental investigation.
