Low\u2010molecular\u2010weight peptides from cod skin have demonstrated anti\u2010inflammatory and mucosal protective effects; however, the mechanism by which they alleviate colitis through gut microbiota modulation remains unclear. This study examined the mechanism by which cod skin collagen oligopeptide powder (CP) affects the gut flora to treat ulcerative colitis (UC). This study evaluated CP in mice with dextran sodium sulfate (DSS)\u2010induced UC and used 16S rRNA sequencing to analyze its effect on the gut flora. Fecal microbiota transplantation (FMT) demonstrated the role of CP in modulating gut microbiota in the treatment of UC. Hematoxylin and eosin staining, immunohistochemistry, histology, and enzyme\u2010linked immunosorbent assay (ELISA) assessed CP's effects on colon structure and inflammation. 16S rRNA sequencing showed that CP therapy significantly altered the diversity and organization of the intestinal microbiota in UC mice. FMT demonstrated that CP alleviates UC by modifying the gut microbiota, providing insights into the underlying mechanisms. CP treatment significantly improved body weight, colon length, and histopathological scores in DSS\u2010induced colitis mice, reduced the levels of NLRP3, Caspase\u20101, ASC, IL\u20101\u03b2, and IL\u201018, promoted colonic healing, and alleviated tissue damage. CP inhibited fibrosis by upregulating ZO\u20101 and Occludin while downregulating \u03b1\u2010SMA, Vimentin, Snail, and Slug. In conclusion, CP may treat colitis in mice by suppressing NLRP3 inflammasome activation via regulation of the gut microbiota.<\/jats:p>","DOI":"10.1002\/fsn3.72162","type":"journal-article","created":{"date-parts":[[2026,8,8]],"date-time":"2026-08-08T05:20:01Z","timestamp":1786166401000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Cod Skin Collagen Peptides Alleviate Ulcerative Colitis by Regulating Gut Microbiota to Inhibit\n                    <scp>NLRP3<\/scp>\n                    Inflammasome Activation"],"prefix":"10.1002","volume":"14","author":[{"given":"Longyi","family":"Piao","sequence":"first","affiliation":[{"name":"Key Laboratory of Cellular Function and Pharmacology of Jilin Province Yanbian University  Yanji China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-0067-0360","authenticated-orcid":false,"given":"Jiaqi","family":"Huo","sequence":"additional","affiliation":[{"name":"Key Laboratory of Cellular Function and Pharmacology of Jilin Province Yanbian University  Yanji China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanru","family":"Dong","sequence":"additional","affiliation":[{"name":"Key Laboratory of Cellular Function and Pharmacology of Jilin Province Yanbian University  Yanji China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuxia","family":"Cao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Cellular Function and Pharmacology of Jilin Province Yanbian University  Yanji China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6726-8819","authenticated-orcid":false,"given":"Xiangdan","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Cellular Function and Pharmacology of Jilin Province Yanbian University  Yanji China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongyuan","family":"Xu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Cellular Function and Pharmacology of Jilin Province Yanbian University  Yanji China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianglan","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Cellular Function and Pharmacology of Jilin Province Yanbian University  Yanji China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lan","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Pathology Yanbian University Hospital  Yanji Jilin China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,7]]},"reference":[{"issue":"10","key":"e_1_2_13_2_1","first-page":"699","article-title":"Ulcerative Colitis","volume":"87","author":"Adams S.
