In this research, we examined the varied expression of genes associated with metabolic reprogramming–related genes in SCI. By employing the Gene Expression Omnibus datasets GSE5296 and GSE47681, 1001 differentially expressed genes (DEGs) were identified through the limma R package. Among these, 871 and 130 genes were upregulated and downregulated, respectively. A subset of 10 metabolic reprogramming–related differentially expressed genes (MRRDEGs) was recognized as key players in metabolic reprogramming. Analyses of enrichment performed using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes indicated that the identified MRRDEGs predominantly participated in processes related to pyruvate metabolism and carbohydrate degradation. Nine hub genes were discerned using a protein–protein interaction network. Subsequently, an SCI mouse model was established using the LISA SCI modeling device, and preliminary validation was conducted through quantitative real-time PCR experiments at various time points after SCI, specifically on days 1, 3, and 7, suggesting their central role in SCI. Receiver operating characteristic curve analysis indicated that these MRRDEGs could be used to diagnose SCI. The CIBERSORT algorithm analysis of immune infiltration identified an inverse relationship between M0 and M2 macrophages. Furthermore, a positive relationship was observed between <i>Ucp2</i> and M0 macrophages, underscoring their essential function in the immune response following SCI. These results highlight MRRDEGs’ importance in SCI and propose their potential roles as targets for therapeutic interventions.</p><h3>Graphical Abstract</h3><p>Using data from the public GEO database, we identified differentially expressed genes associated with metabolic reprogramming in spinal cord injury and successfully validated them through qPCR experiments.</p>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":652,"journal":{"name":"Journal of Molecular Neuroscience","volume":"75 2","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This improvement highlights FXL’s ability to counteract the mitochondrial dysfunction induced by these neurotoxic agents. Additionally, FXL reduces oxidative damage and enhances cell viability.

The progressive accumulation of amyloid-beta (Aβ) plaques and tau tangles triggers neuroinflammation, oxidative stress, and neuronal damage, highlighting the critical need for effective clearance mechanisms. Recent research has identified low-density lipoprotein receptor-related protein 1 (LRP1) as a key factor in the regulation of Aβ clearance, neuroinflammation, and blood–brain barrier integrity, particularly in relation to the liver-brain axis. This review provides a comprehensive examination of the role of LRP1 in AD, focusing on its expression in the brain and liver, its contribution to Aβ metabolism, and its potential as a therapeutic target. Using a systematic literature review, LRP1’s multifaceted roles across various biological processes were explored, including its involvement in Aβ transport, clearance via the liver, and modulation of neuroinflammation. Additionally, the impact of physical exercise, pharmacological interventions, and dietary factors on LRP1 expression levels was investigated, elucidating how these approaches may enhance Aβ clearance. The findings demonstrate that LRP1 expression decreases progressively as AD advances, and that augmenting LRP1 activity—particularly through exercise and drug therapies—can improve Aβ clearance and reduce neuroinflammatory responses. Furthermore, LRP1’s involvement in the liver-brain axis reveals its broader systemic role in AD pathology. In conclusion, targeting LRP1 offers a promising avenue for AD prevention and treatment, providing new insights into the therapeutic potential of enhancing Aβ clearance pathways through the liver-brain axis.</p></div>","PeriodicalId":652,"journal":{"name":"Journal of Molecular Neuroscience","volume":"75 2","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"CD73 Molecule Inhibitor Upregulates miR16 Expression in Experimental Glioblastoma and Inhibits Angiogenesis by Targeting VEGF","authors":"Samaneh Arab,&nbsp;Sahar Ghasemi,&nbsp;Marjan Bahraminasab,&nbsp;Ali Ghanbari,&nbsp;Mina Heidari,&nbsp;Parviz Kokhaei,&nbsp;Abozar Bahrami,&nbsp;Samira Asgharzade","doi":"10.1007/s12031-025-02307-w","DOIUrl":"10.1007/s12031-025-02307-w","url":null,"abstract":"<div><p>The function of CD73 (Cluster of Differentiation 73), an enzyme involved in the formation of adenosine (ADO), in the development of glioblastomas has been demonstrated. Indeed, ADO helps tumor angiogenesis by stimulating endothelial cell migration, proliferation, and tube formation. However, the details of the molecular mechanisms are not yet fully understood. Given the importance of angiogenesis in cancer progression, invasion, and metastasis, this study aimed to investigate how the inhibition of CD73 by adenosine-5′-(α, β-methylene) diphosphate (APCP) affects the angiogenesis process of experimental orthotopic glioblastoma at mRNAs, microRNAs, and protein levels. According to the real-time-polymerase chain reaction (RT-PCR) results, inhibition of CD73 decreased the angiogenesis of glioblastoma by reducing the expression of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor 1-alpha (HIF-1α) by ****<i>P</i> &lt; 0.0001 and **<i>P </i>&lt; 0.01, respectively. Furthermore, immunohistochemical staining showed that this treatment protocol attenuated the expression of VEGF and CD31. Moreover, APCP treatment significantly increased miR-16 expression in glioblastoma model rats by <i>P</i> &lt; 0.001, but no significant change in miR-29A expression was observed. The results showed that the treatment did not lead to systemic damage or significant weight loss. Our results suggest that inhibition of CD73 may reduce the formation of new tumor vessels by inhibiting the VEGF, HIF-1α, and CD31 in this process. Therefore, CD73 may be a practical target and provide new opportunities to improve the treatment of malignant brain tumors.</p></div>","PeriodicalId":652,"journal":{"name":"Journal of Molecular Neuroscience","volume":"75 2","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
