A sulfated glycosaminoglycan (SCP-2) with β-(1→3)-GlcNSp and α-(1→4)-GlcAp as recurring units isolated from S. cucullata. SCP-2 exhibited substantial 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase (HMGCR) inhibition potential (IC50 0.65 mg/mL) in comparison with atorvastatin (IC50 0.72 mg/mL). An in vitro study of SCP-2 (0.1-160 μg/dL) revealed a 77-89% reduction in triglyceride levels in control Caco-2 cells after 4 days of incubation, similar to atorvastatin-treated cells (90%). The acute dyslipidemic efficacy of SCP-2 (at 90 mg/kg body weight) showed timely alleviation of triglyceride and cholesterol levels in tyloxapol-induced rats (∼43% and 81% inhibition at 5 h), which was analogous to the atorvastatin treatment group (∼66% and 71%). Furthermore, SCP-2 (at 90 mg/kg body weight) showed mitigation in triglyceride (> 50%) and cholesterol levels (> 25%) in high-fat high-cholesterol (HFHC) diet-induced rats, similar to the lovastatin treatment group (approximately 62% and 33% inhibition on the 45th day). Histopathological studies of SCP-2 also showed recovery in steatosis, inflammation, and ballooning degradation in liver tissues. Structure-activity relationship analysis suggested the sulfate groups in SCP-2 enhance its anti-dyslipidemic efficacy. The capability of SCP-2 to mitigate cholesterol, triglyceride, and HMGCR levels makes it a prospective functional food against dyslipidemia-related disorders.","PeriodicalId":93932,"journal":{"name":"Chemico-biological interactions","volume":" ","pages":"111371"},"PeriodicalIF":0.0,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142960258","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":" ","pages":"111060"},"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}
