Blood samples were analyzed using automated spectrophotometric techniques to determine OS biomarkers. The results demonstrated that DTDH parameters and classical OS markers exhibited parallel changes; however, no statistically significant differences were detected between the ASD and control groups across all OS markers. Furthermore, no significant association was found between OS biomarkers and autism severity. Moreover, we intentionally restricted our sample to a younger age group to enable a focused examination of OS dynamics during early developmental stages. This study underscores the potential impact of age as a critical determinant in OS-related alterations in autism and highlights the need for further age-stratified investigations to elucidate the role of OS in ASD pathophysiology and its potential diagnostic relevance.</p></div>","PeriodicalId":652,"journal":{"name":"Journal of Molecular Neuroscience","volume":"75 2","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12031-025-02358-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143900739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of the present study was to investigate the combined effect of UA and CA on seizures, neuronal damage, and inflammation induced by PTZ in adult zebrafish.

UA of both doses and CA decreased mean seizure score, and mean seizure time. Importantly, combination of UA 50 mg/kg and CA 60 mg/kg attenuated seizure-like behavioural scores, decreased mean seizure time, mean seizure score and reduced the frequency of clonic-like seizures (score 4) in PTZ-treated zebrafish. A combination of UA 50 mg/kg and CA 60 mg/kg also prevented oxidative stress in PTZ-challenged fish by decreasing lipid peroxidation, AChEs activity and increasing catalase, GSH and SOD levels. Additionally, the combination therapy prevented inflammatory response by declining TNF-α and IL-1β levels and raising IL-10 and Nrf-2 levels. Moreover, combination of UA 50 mg/kg and CA 60 mg/kg significantly improved mitochondrial complex I, II and IV activities as well as increase mitochondrial viability in MTT assay. Furthermore, morphology of neuronal cell was prevented in combination of UA 50 mg/kg and CA 60 mg/kg as seen in H &amp; E staining. The protective effect of UA 50 mg/kg and CA 60 mg/kg cocktail is comparable with standard drug Diazepam. Together, we demonstrate that UA 50 mg/kg and CA 60 mg/kg cocktail significantly attenuated PTZ-induced seizure-like behaviours, brain oxidative stress, mitochondrial dysfunction and morphological damage of neuronal cell in zebrafish, suggesting the involvement of its strong anti-inflammatory and antioxidant mechanisms in neuroprotection.</p></div>","PeriodicalId":652,"journal":{"name":"Journal of Molecular Neuroscience","volume":"75 2","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143879683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
