The intestinal tract hosts a substantial and diverse microbiota involved in various physiological activities and is closely linked to chronic liver disease. Previous studies have indicated that ursolic acid (UA), derived from herbal plants, possesses anti-inflammatory and antifibrotic properties; however, its precise mechanism remains to be elucidated. Consequently, liver fibrosis models were constructed utilizing both the methionine/choline deficieny (MCD) diet and carbon tetrachloride (CCl4) intraperitoneal injections. 16S rRNA was conducted to analyze the intestinal microbiota. Results indicated that UA attenuated liver injury and fibrosis, reduced indices related to liver fibrosis, and decreased the expression levels of NADPH oxidase 2 (NOX2) and NOD like receptor protein 3 (NLRP3). Hepatic fibrosis was alleviated in post-model NOX2 and NLRP3 gene knockout (NOX2-/- and NLRP3-/-) mice in comparison to post-model wild-type (WT) mice. Nonetheless, neither UA treatment nor control treatment significantly improved liver fibrosis in comparison to post-model knockout mice. Furthermore, the liver of NOX2-/- mice exhibited lower levels of NLRP3 expression. Importantly, knockout mice displayed a higher diversity of intestinal microbiota, characterized by an increased presence of beneficial bacteria and a reduced presence of harmful bacteria compared to WT mice. In conclusion, UA exerts antifibrotic effects through the inhibition of the NOX2/NLRP3 inflammasome signaling pathway. UA has the potential to reverse liver fibrosis by modulating this signaling pathway, thereby enhancing the gut microbiota.","PeriodicalId":93932,"journal":{"name":"Chemico-biological interactions","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142585227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wilson disease (WD) is an inherited disorder characterized by impaired copper metabolism. Reproductive damage in male patients with WD is gradually attracting attention. However, the underlying mechanisms of copper toxicity are unclear. In this study, we investigated the role of inflammation and PANoptosis in testicular damage and impaired spermatogenesis caused by copper deposition using the WD model toxic milk (TX) mice. Copper chelator-penicillamine and toll-like receptor 4 (TLR4) inhibitor-eritoran were used to intervene in TX mice in our animal experiment methods. Testis samples were collected from mice for further analysis. The results showed that the morphology and ultrastructure of the testis and epididymis in TX mice were damaged, and the sperm counts decreased significantly. The TLR4/nuclear factor kappa-B (NF-κB) signaling pathway was activated by copper deposition, which led to the upregulation of serum and testicular inflammatory factors in TX mice. Meanwhile, pyroptosis, apoptosis, and necroptosis were significant in the testis of TX mice. Both chelated copper or inhibited TLR4 expression markedly suppressed the TLR4/NF-κB signaling pathway, thereby reducing the expression of inflammatory factors. PANoptosis in the testis of TX mice was also reversed. Our study indicated that pathological copper exposure induces inflammation and PANoptosis through the TLR4/NF-κB signaling pathway, leading to toxic testicular damage and impaired spermatogenesis in WD.","PeriodicalId":93932,"journal":{"name":"Chemico-biological interactions","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140961149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
