Monocyte locomotion inhibitory factor (MLIF), a heat-stable pentapeptide derived from <em>Entamoeba histolytica</em>, has demonstrated the anti-inflammatory capacity. The aim of the current work was to test the protective effects of MLIF in a dextran sulfate sodium (DSS)-induced colitis mouse model. Our findings indicated that MLIF significantly inhibition of colitis development, including body weight, DAI score, colon length, and spleen index. MLIF slowing the progression of inflammation in the colon of mice exposed to DSS, evidenced by HE staining and mRNA expression levels of <em>Il1b</em>, <em>Il6</em>, <em>Il18</em> and <em>Il10</em>. MLIF significantly alleviated intestinal barrier dysfunction in mice exposed to DSS, evidenced by AB-PAS staining and mRNA expression levels of <em>Tjp1</em>, <em>Ocln</em> and <em>Muc2</em>. Importantly, the administration of MLIF in colitis mice exerted beneficial effects on the gut microbiota, enhancing microbial diversity and abundance, and promoting the restoration of gut microbiota homeostasis. Non-targeted metabolomics results suggest that the benefits of MLIF may arise from its modulation of tryptophan metabolism pathways. In conclusion, MLIF prevention inflammation induction and preserves intestinal homeostasis against colitis induced by DSS.</div></div>","PeriodicalId":317,"journal":{"name":"Food and Chemical Toxicology","volume":"202 ","pages":"Article 115545"},"PeriodicalIF":3.9,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143954532","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}

This assumption is further strengthened by comparing human pharmacokinetic Cmax blood levels with <em>in vitro</em> concentrations of berberine that trigger impairment of topo II, a known secondary genotoxicity pathway, revealing a large Margin of Exposure of ≥11900-fold.

Due to their good performance, they are widely used in daily production, such as food packaging, paints, adhesives, children's toys, lubricants and building materials. However, PAEs usually have weak interactions with polymers, which can easily cause environmental pollution in use. These plasticizers have been linked to various health conditions, including inflammatory disorders. They are less intensively studied in the occurrence of inflammation, especially inflammatory bowel disease (IBD), and the necessity to evaluate their pathogenic molecular toxicity is particularly urgent. In this study, network toxicology and molecular docking methods were used to study the toxicological mechanism of IBD induced by four common plasticizers (DBP, DEHP, DEP, DNOP). Potential related targets were predicted using the PharmMapper, SwissStargetPrediction, GeneCards, DisGeNET, OMIM and TTD databases, and 286 related targets were identified. Using Gene Ontology (GO) functional annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment, binding protein-Protein Interaction (PPI) networks and cytoHubba plug-ins, ten relevant signaling pathways (PI3K-Akt signaling pathway, lipid and atherosclerosis, AGE-RAGE signaling pathway in diabetic complications, Proteoglycans in cancer, and so on.) and ten hub genes were identified. Four plasticizers (DBP, DEHP, DEP, DNOP) and the top 10 selected Hub gene targets (SRC, KRAS, PIK3CA, PIK3R1, JAK2, PTPN11, PIK3CD, HRAS, PIK3CG, EGFR) were analyzed by molecular docking. This study provides valuable insights into the molecular mechanisms of plasticizer-induced IBD and highlights the practicality of network toxicology in assessing the toxicity of emerging environmental pollutants. It enhances our understanding of the health risks posed by plasticizers and offers new strategies for mitigating their impact on inflammatory diseases.</div></div>","PeriodicalId":317,"journal":{"name":"Food and Chemical Toxicology","volume":"202 ","pages":"Article 115543"},"PeriodicalIF":3.9,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143941325","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}

The results demonstrated that KFL administration leads to a decrease in embryo absorption, reduces inflammation at the maternal-fetal interface, and balances the T helper 1/T helper 2 ratio, ultimately enhancing pregnancy outcomes. Additionally, KFL was found to enhance placental development, decrease apoptosis, and alleviate oxidative stress in placental tissues of RSA mice. Besides, we investigated the impact of KFL on oxidation-damaged HTR-8/Svneo cells. The findings indicated that KFL mitigates oxidative damage in trophoblast cells by modulating the NF-κB pathway. Furthermore, RNA sequencing revealed that KFL treatment leads to large transcriptome changes in HTR-8/Svneo cells. Overall, the research demonstrated that KFL has the potential to alleviate placental inflammation and oxidative stress, thereby enhancing pregnancy outcomes in RSA mice.
