The results showed that the oral administration of MRPP (low-dose myricitrin, 50 mg/kg BW by gavage; high-dose myricitrin, 250 mg/kg BW by gavage; and <i>Myrica rubra</i> pomace, 500 mg/kg BW by gavage) for 4 weeks significantly reduced fasting blood glucose, glycated serum protein, serum insulin, and insulin resistance index in mice, as well as the dyslipidemia in mice was improved. MRPP was able to improve the structural morphology of hepatocytes and pancreatic β-cells in diabetic mice. Its hypoglycemic mechanism may involve the upregulation of GLUT-4 and IRS-1 genes expression in the PI3K and AMPK signaling pathways, downregulation of GSK-3β, AMPK, PI3K, and AKT genes expression, and enhancement of the activity of enzymes related to glycogen synthesis and glucose metabolism. Research findings on 16S rRNA suggest that MRPP has the ability to alter the composition of the gut microbiota, impede the growth of harmful bacteria, and foster the growth of beneficial bacteria. Therefore, MRPP was capable of reshaping the specific gut microbial community and supporting its application as a novel supplement in functional foods for the treatment of T2D.","PeriodicalId":212,"journal":{"name":"Molecular Nutrition & Food Research","volume":"67 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

LAB strains, known for their role in food fermentation, were assessed for their ability to influence cytokine production in THP-1 macrophages, maintain intestinal epithelial barrier integrity in Caco-2 monolayers, exhibit antioxidant activity, and produce specific organic acids and sugars. The research demonstrated that live LAB strains significantly upregulated the anti-inflammatory cytokine IL-10, particularly under inflammatory conditions, while TI strains exhibited notable antioxidant and anti-inflammatory properties. TI strains showed a greater ability to protect epithelial barrier function and reduce pro-inflammatory cytokine secretion than live strains, suggesting a promising role for postbiotics. The findings underscore the potential of LAB from fermented foods, demonstrating that postbiotic derivatives can differently influence inflammation compared to live bacteria, highlighting their potential as immune-enhancing agents, capable of modulating immune responses and offering therapeutic benefits against inflammation-related disorders. However, the limitations of in vitro models highlight the need for further in vivo and clinical studies to validate these effects and fully uncover the health benefits of these LAB strains for humans.","PeriodicalId":212,"journal":{"name":"Molecular Nutrition & Food Research","volume":"37 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These compounds that comprise the class of phenolic acids, stilbenes, lignans, coumarins, flavonoids, and tannins have a wide range of employment, from food production to medical usages. Among the beneficial applications of polyphenols, their antiviral activity is gaining importance due to the increased prevalence of drug-resistant viruses such as herpes and hepatitis B viruses. In the present review, we provide an overview of the most promising or commonly used antiviral polyphenols and their mechanisms of action focusing on their effects on enveloped viruses of clinical importance (double-stranded linear or partially double-stranded circular DNA viruses, negative sense single-stranded RNA viruses with nonsegmented or segmented genomes, and positive sense single-stranded RNA viruses). The present work emphasizes the relevance of polyphenols, in particular epigallocatechin-3-gallate and resveratrol, as alternative or supportive antivirals. Polyphenols could interfere with virtually all steps of viral infection, from the adsorption to the release of viral particles. The activity of polyphenols against viruses is especially relevant given the risk of widespread outbreaks associated with viruses, remarked by the recent COVID-19 pandemic.","PeriodicalId":212,"journal":{"name":"Molecular Nutrition & Food Research","volume":"13 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was designed to investigate the protective effects of oral propolis supplementation in AFB1-exposed rats. Thirty-two male Sprague-Dawley rats were divided into four groups: control, AFB1, propolis, and AFB1+propolis. After 4 weeks, serum oxidative stress markers were examined, and gut microbiota was analyzed by 16S rRNA sequencing. Intestinal sections were processed by Hematoxylin &amp; Eosin staining, and the expression level of tight junction proteins was assessed by immunostaining. Propolis supplementation in AFB1-exposed rats tended to decrease oxidative stress, and it also restructured the gut microbiota by preventing a decrease in the relative abundances of <i>Lactobacillus</i>, <i>Roseburia</i>, and <i>Phascolarctobacterium</i>. Propolis restored intestinal permeability impaired by AFB1 by ameliorating intestinal morphological damage and increasing the expression levels of tight junction proteins.

Research indicates that omega-3 fatty acids can modulate inflammatory pathways, potentially reducing chronic inflammation and enhancing immune function. This review discusses the intersection of nutrigenomics and nutriepigenomics, focusing on how omega-3 fatty acids influence gene expression, immune function, and overall health. The immune system is a complex network responsible for defending the body against pathogens and maintaining internal balance. Comprised of innate and adaptive immunity, the system involves various cells, tissues, and organs working together to combat infections and prevent diseases. Omega-3 polyunsaturated fatty acids (PUFAs), particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), play a significant role in modulating the immune system. These fatty acids influence immune cell function, membrane fluidity, and signaling processes, enhancing immune responses and reducing inflammation. Furthermore, EPA and DHA affect several signaling pathways, reducing the expression of proinflammatory cytokines and inhibiting nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) activation, a critical transcription factor in the inflammatory response. Additionally, they activate PPAR-γ, further diminishing inflammatory gene expression. As precursors to specialized proresolving lipid mediators, EPA and DHA help shift the lipid mediator profile from proinflammatory to antiinflammatory derivatives, thus aiding in the resolution of inflammation.","PeriodicalId":212,"journal":{"name":"Molecular Nutrition & Food Research","volume":"37 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143737108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the pancreatic molecular mechanisms involved in cellular stress, inflammation, mitogenesis, and apoptosis in metabolic disease induced by high-fructose diet. Here, we used biochemical, histopathological, Western blot, and immunohistochemistry methods to determine the metabolic and pancreatic alterations in male <i>Wistar</i> rats fed 20% fructose in drinking water for 15 weeks. High-fructose consumption in rats increased the immunopositivity and protein expression of glucose transporter 2 (GLUT2) and insulin in the pancreatic tissue, in association with abdominal adiposity, hyperglycemia, and hypertriglyceridemia. The expressions of cellular stress markers, glucose-regulated protein-78 (GRP78) and PTEN-induced putative kinase 1 (PINK1), were increased in the pancreas. The levels of interleukin (IL)-6, nuclear factor kappa B (NFκB), tumor necrosis factor α (TNFα), and IL-1β and components of the Nod-like receptor protein 3 (NLRP3) inflammasome were elevated. Excess fructose intake stimulated the activation of mitogenic extracellular signal-regulated kinases 1/2 (ERK1/2), p38, and c-Jun N-terminal kinase (JNK)1 as well as the apoptotic p53 and Fas pathways in the pancreas of rats. There was also an increase in caspase-8 and caspase-3 cleavage. Our findings revealed that dietary high-fructose in the pancreas causes hyperinsulinemia due to the upregulation of GLUT2 together with cellular stress and inflammatory markers, thereby stimulates mitogenic mitogen-activated protein kinase (MAPK) and apoptosis pathways, resulting in a complex pathological situation.","PeriodicalId":212,"journal":{"name":"Molecular Nutrition & Food Research","volume":"30 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143723451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we conducted untargeted metabolomic analysis and network pharmacology prediction. Subsequently, a compound-reaction-enzyme-gene network was constructed based on the results of metabolomics and network pharmacology to elucidate potential connections. The results demonstrated that GAL can improve renal interstitial fibrosis and inflammatory infiltration and reduce serum levels of uric acid (UA), urea nitrogen (UREA), and creatinine (CREA). Metabolome analysis indicated that GAL affected thiamine, pyrimidine, nicotinate, nicotinamide, pyruvate, glyoxylate, and dicarboxylate metabolism. Network pharmacology and experimental results showed that GAL reduced the key target expression of the tumor protein P53 (TP53), tumor necrosis factor (TNF), signal transducer and activator of transcription 3 (STAT3), heat shock protein 90 alpha family class A member 1 (HSP90aa1), albumin (ALB), and caspase-3 (CASP3). GAL also downregulated the expression of Janus kinase 2 (JAK2), phospho-JAK2 (P-JAK2), and phospho-STAT3 (P-STAT3).
