Salvianic acid A (SAA) protective mechanisms primarily include anti-inflammation, anti-oxidative stress, and modulation of immune system function.

However, the precise action mode and underlying mechanism of SAA in modulating hepatic metabolism to combat hepatic fibrosis remain incompletely understood. This study aimed to investigate the metabolic mechanism by which SAA improves hepatic fibrosis based on metabolomics and transcriptomics profiling. A mouse model of carbon tetrachloride (CCl<sub>4</sub>)-induced hepatic fibrosis mouse model was established, and protective effects of SAA were evaluated through pathological characteristics. Integrated metabolomics and transcriptomics analysis revealed three key altered metabolic pathways: bile secretion, carbohydrate digestion and absorption, and regulation of lipolysis in adipocytes. SAA modulated the bile secretion pathway, dependent on reducing water channel protein <em>Aqp1</em>, cholesterol synthesis enzyme <em>Hmgcr</em> and Na<sup>+</sup>/K<sup>+</sup>-ATPase enzyme <em>Atp1a3</em>, accompanied by up-regulating metabolites glutathione and glucose levels. SAA also regulated carbohydrate digestion and absorption by decreasing the glucose homeostasis-related <em>Akt3</em>, essential enzyme <em>G6pc</em> for gluconeogenesis/glycogenolysis and glucose transporter <em>Atp1a3</em> with a concomitant increase of metabolites D-galactose, maltose, and sucrose levels. Moreover, SAA improved lipolysis in adipocytes in liver fibrosis through inhibiting lipolysis related <em>Prkg1,</em> lipid transporter <em>Fabp4,</em> lipolysis-associated <em>Akt3</em> and increasing lipolysis mediator <em>Adrb3</em>, along with upregulated levels of metabolites adenosine monophosphate and norepinephrine.

Fluvoxamine, a CYP1A2 inhibitor with anti-inflammatory effects, and CYP1A2 affects estrogen metabolism. However, its potential as a COPD treatment and interaction with estrogen in women are unclear. This study explored fluvoxamine's efficacy in female mice with cigarette smoke (CS)-induced COPD. Administering 8 mg/kg fluvoxamine intraperitoneally markedly reduced CS-induced lung damage, lowering histopathological injury and pro-inflammatory cytokines in bronchoalveolar lavage fluid and serum. RNA-seq analysis revealed that fluvoxamine significantly suppressed the upregulation of inflammation-related genes. Furthermore, the KEGG and GSEA analysis of differentially expressed genes in lung transcriptomics revealed that the metabolism of xenobiotics by cytochrome P450 and JAK-STAT signaling pathway were regulated after fluvoxamine treatment. WB and ELISA assay also demonstrated a significant decrease in CYP1A2 and estrogen levels following treatment with fluvoxamine or tamoxifen. Crucially, fluvoxamine matched tamoxifen (an estrogen inhibitor) in improving lung structural parameters (mean linear intercept, destructive index). These results suggest fluvoxamine mitigates COPD by inhibiting CYP1A2, reducing inflammatory mediators and estrogen.

The imbalance of respiratory microbiota and metabolites plays a crucial role in the progression of allergic asthma. However, there is limited knowledge available regarding the alterations in respiratory microbiota and metabolites and their impact on the host in the context of asthma. The aim of this study was to investigate the potential pathways involved in the development of asthma through the analysis of lung flora and metabolites. A mouse model of house dust mite (HDM)-induced asthma was established, and alveolar lavage samples were collected for microbiome 16S rRNA sequencing and untargeted metabolic analysis. Microbiological analyses indicated a significant alteration in the microbiota after 4 and 6 weeks of HDM nebulisation stimulation. This was characterized by a decrease in microbial diversity, as well as reductions in the relative proportion of <em>Gallionella</em> and <em>Lactobacillus</em>. Conversely, the abundance of <em>Flavobacterium</em> and <em>Ralstonia</em> increased in the HDM4W and HDM6W groups, respectively. Metabolomic analyses revealed seven distinct metabolites, among them L-malic acid, which were linked to signaling pathways in a mouse model of HDM-induced asthma. The correlation analysis demonstrated a positive association between L-malic acid and <em>Rhodanobacter</em> and <em>Nocardioides</em>. L-malic acid was discovered to be efficacious in reducing airway inflammation in mice with house dust mite-induced asthma. Further analysis revealed that this change was linked to lipid peroxidation and changes in ferroptosis markers, namely GPX4 and FTH. These findings suggest that L-malate inhibits ferroptosis. However, the introduction of ferroptosis inducers, such as Erastin, was observed to negate the beneficial effect of butyrate. In summary, this research implies that the respiratory microbiota metabolite L-malic acid lessens airway inflammation in asthma by inhibiting ferroptosis, offering a potential approach for managing asthma.</div></div>","PeriodicalId":23174,"journal":{"name":"Toxicology and applied pharmacology","volume":"500 ","pages":"Article 117396"},"PeriodicalIF":3.3,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144089733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
