Probiotics have the potential to alleviate HUA.<\/jats:p><\/jats:sec>Methods<\/jats:title>This study established a hyperuricemia model using Caenorhabditis elegans<\/jats:italic> (C. elegans<\/jats:italic>), and studied the anti-hyperuricemia activity and potential mechanisms of Weizmannella coagulans<\/jats:italic> BC99 (W. coagulans<\/jats:italic>) at different concentrations (107<\/jats:sup> CFU\/mL BC99, 108<\/jats:sup> CFU\/mL BC99). Subsequently, we utilized UPLC-Q-TOF\/MS to investigate the impact of BC99 on endogenous metabolites in C. elegans<\/jats:italic> and identified pathways and biomarkers through differential metabolomics analysis.<\/jats:p><\/jats:sec>Results<\/jats:title>The results of this study showed that BC99 treatment significantly reduced the expression of P151.2 and T22F3.3 (p<\/jats:italic> &lt; 0.05), reduced the levels of UA and xanthine oxidase (XOD) in nematodes (p<\/jats:italic> &lt; 0.05), while extending their lifespan and movement ability (p<\/jats:italic> &lt; 0.05). Mechanistically, BC99 activates the transcription factors DAF-16 and SKN-1, thereby inducing the expression of stress response genes, enhancing the activity of antioxidant enzymes and tolerance to heat stress in the body, and reducing the production of ROS (p<\/jats:italic> &lt; 0.001). This effect was most significant in the H-BC99 group. Furthermore, non-targeted metabolomics indicated that BC99 predominantly regulated pathways associated with amino acid metabolism (Carnosine), glycerophospholipid metabolism, and purine metabolism.<\/jats:p><\/jats:sec>Discussion<\/jats:title>These results underscore BC99 as an effective and economical adjunct therapeutic agent for hyperuricemia, providing a scientific basis for further development and application.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fmicb.2024.1498540","type":"journal-article","created":{"date-parts":[[2024,12,11]],"date-time":"2024-12-11T09:35:33Z","timestamp":1733909733000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["Weizmannia coagulans BC99 alleviates hyperuricemia and oxidative stress via DAF-16\/SKN-1 activation in Caenorhabditis elegan"],"prefix":"10.3389","volume":"15","author":[{"given":"Yinyin","family":"Gao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheng","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junfei","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengyao","family":"Duan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuan","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lina","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaobin","family":"Gu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,12,11]]},"reference":[{"key":"B1","first-page":"1\u20132","article-title":"Effect of increasing hydrogen peroxide concentrations on head oscillations of Caenorhabditis elegans.","volume":"5","author":"Ahluwalia","year":"2016","journal-title":"Expedition"},{"key":"B2","doi-asserted-by":"publisher","first-page":"861","DOI":"10.1080\/10715762.2016.1187268","article-title":"Acacetin promotes healthy aging by altering stress response in Caenorhabditis elegans.","volume":"50","author":"Asthana","year":"2016","journal-title":"Free Radic.
