The LC-MS/MS analysis of AESC revealed gallic acid, ellagic acid, quercetin, malic acid, and citric acid as major antidiabetic phytoconstituents. Administration of AESC (250 mg/kg) normalized fasting blood glucose levels to those of healthy control rats. Moreover, AESC increases antioxidant levels and downregulates ER and inflammatory markers. Histopathological evaluation showed improved pancreatic tissue architecture, and immunohistochemistry revealed enhanced insulin expression within the islets. Mechanistically, AESC alleviated ER stress and oxidative damage through the ATF-6/CHOP/NF-κB signaling axis. Furthermore, serum metabolomics indicated aberrant accumulation of branched-chain amino acids and reduced 3-hydroxybutyrate levels (increased ketolysis) in diabetic rats that were reversed by AESC. This study is limited by using a single dosage of AESC and short-term evaluation, emphasizing acute rather than long-term effects. Furthermore, the lack of in vitro validation and genetic knockdown approaches restricts confirmation of the specific mechanisms underlying the antidiabetic action of the extract. Future studies employing multiple dosage regimens, chronic treatment models, and molecular validation strategies are warranted to establish the long-term efficacy, safety, and mechanistic specificity of AESC as a potential therapeutic for T1DM.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s13205-025-04523-y.</p>","PeriodicalId":7067,"journal":{"name":"3 Biotech","volume":"15 10","pages":"356"},"PeriodicalIF":2.9,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12449296/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145111568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This signature effectively stratified patients into high- and low-risk groups with significantly different overall survival, achieving area under the curve (AUC) values greater than 0.7 for 1-, 2-, and 3-year survival prediction. A high-risk status correlated with an immunosuppressive tumor microenvironment, characterized by lower infiltration of B cells and CD8 + T cells, and was associated with reduced sensitivity to multiple chemotherapeutic agents, including Cisplatin and 5-Fluorouracil. Conversely, a low-risk status was linked to greater immune cell infiltration and higher predicted chemosensitivity. At the single-cell level, pseudotime analysis revealed that macrophage maturation significantly correlated with a decreasing risk score, suggesting that mature macrophages may contribute to a favorable prognosis. Furthermore, cell communication analysis identified high-risk macrophages as dominant drivers of a pro-tumorigenic microenvironment via signaling pathways, such as SPP1 and complement.
