Effects of α‐T‐13′‐COOH on cell viability and adaptive stress response are not well understood. The present study aims to investigate the concentration‐dependent effects of α‐T‐13′‐COOH on cellular redox homeostasis, genotoxicity, and cytotoxicity in murine RAW264.7 macrophages as a model system.Methods and resultsMurine RAW264.7 macrophages are exposed to various dosages of α‐T‐13′‐COOH to determine its regulatory effects on reactive oxygen species (ROS) production, DNA damage, expression of stress‐related markers, and the activity of ROS scavenging enzymes including superoxide dismutases, catalase, and glutathione‐S‐transferases. The impact on cell viability is assessed by analyzing cell proliferation, cell cycle arrest, and cell apoptosis.Conclusionα‐T‐13′‐COOH influences ROS production and induces DNA damage in a dose‐dependent manner. The metabolite modulates the activity of ROS‐scavenging enzymes, with significant changes observed in the activities of antioxidant enzymes. A biphasic response affecting cell viability is noted: sub‐micromolar doses of α‐T‐13′‐COOH promote cell proliferation and enhance DNA synthesis, whereas supraphysiological doses lead to DNA damage and cytotoxicity. It hypothesizes an adaptive stress response, characterized by upregulation of ROS detoxification mechanisms, enhanced cell cycle arrest, and increased apoptosis, indicating a correlation with oxidative stress and subsequent cellular damage.","PeriodicalId":212,"journal":{"name":"Molecular Nutrition & Food Research","volume":"166 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642629","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}

It highlights how diet significantly influences gut microbiota composition, with different dietary patterns fostering diverse microbial communities. These diet-induced changes in the microbiome impact human metabolism by affecting inflammation, energy balance, and insulin sensitivity, particularly through microbial metabolites like short-chain fatty acids (SCFAs). Focusing the key mediators like endotoxemia and systemic inflammation, and introduces personalized microbiome-based therapeutic strategies, it also investigates the effects of dietary components—fiber, polyphenols, and lipids—on microbiota and insulin sensitivity, along with the roles of protein intake and amino acid metabolism. The study compares the effects of Western and Mediterranean diets on the microbiota-insulin resistance axis. Therapeutic implications, including probiotics, fecal microbiota transplantation (FMT), and personalized diets, are discussed. Key findings reveal that high-fat diets, especially those rich in saturated fats, contribute to dysbiosis and increased intestinal permeability, while high-fiber diets promote beneficial bacteria and SCFAs. The review underscores the future potential of food and microbiota interventions for preventing or managing insulin resistance.","PeriodicalId":212,"journal":{"name":"Molecular Nutrition & Food Research","volume":"12 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642680","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}

TPA intake alters the expression of 351 genes compared to EA intake, including 11 downregulated and 340 upregulated genes (fold change [FC] &gt;1.5, <i>p</i> &lt; 0.05). TPA compares to EA upregulated: Slc5a8, Lcn2, Csf3, Scube1, Mapk13, Bdkrb2, Ctla2a, Slc2a1, Oas3, Cx3cl1, Oas2, Nlrp6, Pycard, Cyba, Ddr1, and Prkab1 and downregulated Fas gene. These genes are related to the NOD-like receptor, lipid and atherosclerosis, IL-17 signaling, TNF, nonalcoholic fatty liver disease, cytokine–cytokine receptor interaction, adipocytokine, glucagon, insulin resistance, and inflammatory mediator regulation of TRP channels signaling.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>TPA intake has a distinct impact on the regulation of inflammation and diabetes-related pathways in adipose tissue compared to EA.</p>\u0000 </section>\u0000 </div>","PeriodicalId":212,"journal":{"name":"Molecular Nutrition & Food Research","volume":"68 21","pages":""},"PeriodicalIF":4.5,"publicationDate":"2024-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mnfr.202400290","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142431471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
