Exosomes could mediate intercellular communications and play key roles in the occurrence and development of many diseases including NAFLD and HCC. However, expressions and roles of the genes related to exosomes in NAFLD-related HCC remain unclear. The objective of this study was to investigate the expressions and diagnostic values of exosome-related genes in NAFLD-related HCC. Firstly, two risk subgroups of patients with NAFLD-related HCC from the gene expression omnibus (GEO) database were identified based on exosome-related genes. High levels of memory CD4&lt;sup&gt;+&lt;/sup&gt; T cells and low expressions of immune checkpoint genes were observed in the group with highly expressed genes which could promote exosome secretion. Subsequently, the logistic regression analysis was used to identify the three selected exosome-related genes and generate the formula in the NAFLD-related HCC cohort based on the three selected exosome-related genes. Receiver operating characteristic (ROC) curve analysis confirmed the good predictive power of the formula, and the area under the curve (AUC) of risk score was 0.736 for differentiating tumor tissues of NAFLD-related HCC patients from liver tissues of other groups. Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) pathway enrichment analysis showed abundant metabolism-related pathways, including \"glyoxylate and dicarboxylate metabolism\" and \"carbon metabolism pathway\" were screened out in differentially expressed genes (DEGs) between the high and low risk-score groups. The risk score was also positively correlated with memory CD4&lt;sup&gt;+&lt;/sup&gt; T cells and negatively associated with immune checkpoint genes including programmed cell death 1 (PD1), programmed cell death ligand 1 (PDL1), and programmed cell death ligand 2 (PDL2). The results of mouse model showed that the mRNA and protein expression levels of vacuolar protein sorting 45 homolog (VPS45) and vesicle associated membrane protein 5 (VAMP5) were increased in the liver tissue of NAFLD-related HCC mice, and the exophilin 5 (EXPH5) expression was decreased. And the proportion of CD4&lt;sup&gt;+&lt;/sup&gt; T cells was positively correlated with the relative mRNA expression of VPS45 and VAMP5, and negatively correlated with the relative mRNA expression of EXPH5 in liver tissues of NAFLD-related HCC mice. Finally, the prognostic potential of the exosome-related formula was analyzed in the HCC cohort from the cancer genome atlas (TCGA) database, and patients in the group with highly expressed exosome-promoted genes showed significantly reduced overall survival (OS). We performed univariate and multivariate Cox regression analysis and found that risk score was an independent prognostic factor (HR = 1.75, 95% CI:1.20-2.54, p &lt; 0.01).

The miRNA-target genes prediction, conduct Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) functional enrichment analyses were performed with the Database for Annotation, Visualization and Integrated Discovery (DAVID) 6.8.

Traditional graph-theoretical approaches have been widely employed to study ASD biomarkers; however, these methods are often limited to static topological measures and lack the capacity to capture spectral characteristics of brain activity, especially in multimodal data settings. This limits their ability to model dynamic neural interactions and reduces their diagnostic precision. To overcome these limitations, we propose a Graph Signal Processing (GSP)-based framework that integrates spectral-domain features with topological descriptors to model brain connectivity more comprehensively. Using publicly available fMRI and EEG datasets, we construct subject-specific connectivity graphs where nodes represent brain regions and edges encode functional interactions. We extract advanced GSP features such as Graph Fourier Transform coefficients, spectral entropy, and clustering coefficients, and combine them using Principal Component Analysis (PCA). These are classified using a Support Vector Machine (SVM) with a radial basis function (RBF) kernel. The proposed model achieves 98.8% classification accuracy, significantly outperforming prior multimodal GSP studies. Feature ablation analysis reveals that spectral entropy contributes most to this improvement, with its removal resulting in a nearly 30% performance drop. Additionally, a 25% sparsity threshold in graph construction was found to maximize both robustness and computational efficiency. These findings demonstrate that incorporating frequency-domain information through GSP enables a more discriminative and biologically meaningful representation of ASD-related neural patterns, offering a promising direction for accurate diagnosis and biomarker discovery.</p>","PeriodicalId":21811,"journal":{"name":"Scientific Reports","volume":"15 1","pages":"22933"},"PeriodicalIF":3.8,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144544491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work leverages an advanced statistical modeling approach based on stochastic differential equations to analyze post-contrast T1-weighted brain MRI images that require minimal data and offer rapid processing times.

Recently, the combination of immune checkpoint blockers paired with radiotherapy has shown promise in preclinical murine GBM models. Human clinical trials have largely failed. One reason for this may be the discrepancy between radiation protocols utilized in preclinical models versus clinical practice. For translational relevance, defining correct and comparable radiation dosages and schedules to achieve optimal synergy with immunotherapeutic drugs, is essential. We used the GL261-based syngeneic mouse GBM model to compare the effects of two radiation regimens on tumor cell growth and survival. We assessed the in vivo effects of a single dose of 10 Gy (10Gyx1) or five consecutive doses of 2 Gy (2Gyx5) on the tumor immune microenvironment over time and compared their efficacy when combined with anti-PD-1 in vivo. Our data show that the 10Gyx1 regimen is more effective than 2Gyx5 at inhibiting tumor cell proliferation and growth in vitro and in vivo. Both regimens preserved the antigen-presenting ability of both dendritic cells and local microglia, but 10Gyx1 led to the highest lymphocyte infiltration. The combination of radiation with the checkpoint blocker anti-PD-1 was advantageous for both radiation regimens with animals treated with the 10Gyx1 regimen surviving the longest. Our study highlights how radiation regimen choices may impact the translation of preclinical findings, and in particular, the effects of radiation and immunotherapy in GBM.

The HbA1c decreased from 5.8 ± 0.05% in HFFD to 4.4 ± 0.12% in HFFD + SA and 4.1 ± 0.16% in HFFD + SANPs treatment groups. The administration of SANPs resulted in a considerable improvement (p < 0.001) in the activity of glyoxalase-1 (Glo1, 0.19 ± 0.003 U/mg protein), glyoxalase-2 (Glo2, 0.14 ± 0.002 U/mg protein) and hexokinase-2 (29.19 ± 2.24 ng/dL). There was a significant decrease (p < 0.001) in malondialdehyde (MDA) levels along with increased glutathione (GSH), superoxide-dismutase (SOD) and catalase activity. The in-silico analysis indicated potential binding affinities with hexokinase 2 (-5.4), IL-6 (-5.7), catalase (-5.8), MDA (-5.4) and GSH (-5.1). Furthermore, these interventions resulted in enhancements in the plasma concentrations of lipid profile components as well as improvements in liver function tests and expression of pro-inflammatory cytokines including IL-6, IL-8 and NF-κB. Utilization of SANPs holds promise as a therapeutic strategy for mitigating hyperglycemia.</p>","PeriodicalId":21811,"journal":{"name":"Scientific Reports","volume":"15 1","pages":"22778"},"PeriodicalIF":3.8,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144544654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
