Epigallocatechin-3-gallate (EGCG), a polyphenol present in green tea, exhibits antioxidant properties that can protect normal cells from oxidative stress. The findings suggest that exposure to BCDMH results in a reduction of antioxidant enzyme activity, whereas EGCG supplementation enhances crayfish immunity and alleviates damage. Moreover, BCDMH exposure is associated with a decrease in total hemocyte count and an increase in apoptosis rate; however, EGCG demonstrates a protective effect against BCDMH-induced cytotoxicity. Histopathological analysis indicates that exposure to BCDMH results in hepatopancreatic damage in crayfish, which is mitigated by EGCG. To identify the genes and pathways influenced by EGCG, a comparative transcriptome analysis was performed. Gene Ontology (GO) analysis revealed that proteolysis and innate immune response are significant biological processes induced by EGCG. Furthermore, KEGG pathway analysis identified endocytosis and phagosome as critical pathways modulated by EGCG. EGCG effectively enhanced the survival of crayfish challenged with <i>V. alginolyticus</i> following BCDMH exposure This study contributes to fully understand the mechanisms of EGCG in reducing the immunotoxicity of antibiotic residues on aquatic animals.</p></div>","PeriodicalId":690,"journal":{"name":"Marine Biotechnology","volume":"27 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After 24 h of salt-alkali stress (SA group), 1378 differentially expressed genes (DEGs) were identified, with enriched pathways including glycerophospholipid metabolism, serine, taurine, and hypotaurine metabolism. Additionally, 341 significantly different metabolites (SDMs) were found, primarily involved in taurine and hypotaurine metabolism, purine metabolism, and the FoxO signaling pathway, etc. Both DEGs and SDMs were notably enriched in hypotaurine metabolism, glycerophospholipid metabolism, and the mTOR signaling pathway, showing significant upregulation in the SA group. Correlation analysis found that the integrated regulatory network was involved in the synthesis of taurine, glycerophospholipids, and L-glutamic acid, and the metabolism of 3-mercaptopropionic acid. These results suggest that low salinity and alkalinity induce stress responses in <i>S. constricta</i> by regulating osmotic balance, phospholipid synthesis, and lipid metabolism.

The present study envisaged the understanding of the impact of MCP on the ovarian tissues of <i>Anabas testudineus</i> (climbing perch), an air-breathing food fish often found close to agricultural fields, making it a valuable bio-indicator of agrochemical contamination. Transcriptome profiling of ovarian tissues in response to 45 days of MCP exposure at sub-lethal concentrations was performed. Using Illumina platform sequencing, a total of 144.51 million reads were produced. After filtering and trimming, 138.82 million high-quality reads were obtained, of which 96.10% were mapped to the Anabas genome. Expression analysis revealed a total of 54 significant differentially expressed genes (DEGs), including 28 upregulated genes, and 26 downregulated genes compared to the control group (Log2 FC > ± 1 and, adjusted <i>p-value</i> < 0.05). Gene ontology analysis of the DEGs revealed associations with molecular, biological, and cellular functions. Key detoxification genes, such as <i>glutathione S-transferase</i> and <i>UDP-glucuronosyltransferase</i>, were significantly upregulated, indicating an enhanced detoxification response to MCP. In contrast, <i>cytochrome P450 family 1 subfamily A (cyp1a1)</i>, a gene critical for steroid hormone metabolism, was downregulated, suggesting disruptions in hormone regulation. Functional enrichment analysis highlighted several affected processes, including steroid hormone biosynthesis, oocyte meiosis, apoptosis, and progesterone-mediated oocyte maturation. The randomly selected eight DEGs using RT-qPCR confirmed consistent gene expression levels in line with the transcriptome data.
