This research aims to explore the regulatory effects of ZLE and tricin on astroglial dysfunction, utilizing astrocytic differentiated C6 cells (passages 75~85) subjected to Aβ and high-dose insulin, as well as scopolamine-induced mice. Results revealed that ZLE (500 μg/ml) and tricin (1 μg/ml) significantly upregulated the expression of astrocyte proteins GFAP and AQP4, brain-derived neurotrophic factor (BDNF), low-density lipoprotein receptor-related protein 1 (LRP1), and matrix metalloproteinases (MMPs) in C6 cells treated with Aβ and high-dose insulin. Furthermore, oral administration of ZLE (100 and 300 mg/kg) and tricin (0.3 mg/kg) in mice led to an increase in acetylcholine (ACh) levels and upregulation of insulin-degrading enzyme (IDE), LRP1, and MMPs, while reducing the levels of acetylcholinesterase (AChE), Aβ and ApoE4. These findings suggest that ZLE and tricin may ameliorate Aβ and high-dose insulin-induced astrocyte dysfunction in C6 cells and scopolamine-treated mice, potentially through the AQP4/LRP1 pathway.</p>","PeriodicalId":16481,"journal":{"name":"Journal of microbiology and biotechnology","volume":"35 ","pages":"e2412026"},"PeriodicalIF":2.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11896795/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143523663","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}

BlingLife<sup>®</sup>-marigold extract (BLM) is an alcohol extract of magrigold, which contains abundant lutein, zeaxanthin and meso-zeaxanthin. This study aimed to explore the role and potential mechanisms of BLM in blue light-induced retinal damage both in vivo and in vitro. Rats or human retinal pigment epithelial cell line (ARPE-19) were exposed to blue LED light with or without BLM treatment. The retinal morphology changes of rat were evaluated by H&E staining. Mitochondrial morphology was examined by using a transmission electron microscope. Besides, mitochondria oxidative stress was evaluated by detecting mitochondrial membrane potential, ROS, MDA and SOD levels. By measuring γH2AX expression and performing SA-β-galactosidase (gal) staining, cell senescence was assessed. Additionally, cell cycle was detected using flow cytometry. Western blot was employed to examine the expression of NRF2 and HO-1. Results indicated that BLM could protect against blue light-induced damage of rat retinal tissues and ARPE-19 cells, as evidenced by the improved histopathological changes, alleviated mitochondria oxidative stress and attenuated senescence of tissues and cells. More importantly, BLM activated NRF2/HO-1 signaling, and addition of NRF2 inhibitor ML385 significantly blocked the protective effects of BLM on ARPE-19 cells exposed to blue light. In conclusion, BLM can provide an effective protection against blue light-induced retinal damage at least partly by activating NRF2/HO-1 signaling, suggesting that BLM may be useful for the prevention of blue light-induced retinal injury.</p>","PeriodicalId":16481,"journal":{"name":"Journal of microbiology and biotechnology","volume":"35 ","pages":"e2411037"},"PeriodicalIF":2.5,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11896799/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143523664","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}
