In recent years, targeting the suppression of microglia-mediated neuroinflammation has emerged as a principal therapeutic strategy for RIR. Ganoderma lucidum polysaccharide (GLP), a pivotal bioactive extract of Ganoderma lucidum, has been demonstrated to possess efficacious anti-neuroinflammatory properties, while the precise impact of it on RIR injury remains incompletely elucidated. In this study, the RIR model was induced in Sprague-Dawley rats by elevating the intraocular pressure to 80 mmHg for 60 min. Our findings revealed that GLP significantly alleviated inflammatory processes by impeding the secretion of pro-inflammatory cytokines while facilitating that of anti-inflammatory cytokines. Moreover, the administration of GLP also promoted the polarization of microglia from the M1 phenotype to the M2 phenotype. Further investigation of the treatment mechanism indicated that the regulatory effects of GLP were presumably mediated by the inhibition of the JAK2/STAT3 signaling pathway. To summarize, we provided a novel insight into the mechanisms by which GLP ameliorated RIR injury, thereby indicating that it could be identified as a promising candidate for the management of RIR-related diseases.</div></div>","PeriodicalId":8771,"journal":{"name":"Biochemistry and Biophysics Reports","volume":"41 ","pages":"Article 101926"},"PeriodicalIF":2.3,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143143272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Celastrol, a bioactive compound derived from <em>Tripterygium wilfordii Hook.F</em>, is recognized for its anti-inflammatory and anti-fibrotic properties. This study aimed to investigate the renoprotective effects of celastrol against high glucose (HG)-induced damage in human kidney 2 (HK-2) cells. Briefly, HK-2 cells were exposed to high glucose and treated with celastrol. Cell viability and apoptosis were evaluated using CCK-8 assay kit and flow cytometry, respectively. The pro-inflammatory cytokines, oxidative stress markers, and fibrotic-related proteins were measured using ELISA and immunoblotting. To further confirm the mechanistic actions of celastrol, the PI3K/Akt/NF-κB pathway was examined, and HG-treated cells were co-incubated with the NF-κB inhibitor bortezomib. Our result revealed that celastrol at the moderate concentration of 50 nM mitigated HG-induced toxicity, suggesting an optimal therapeutic window. Celastrol improved cell viability and reduced apoptosis in HG-treated HK-2 cells. It significantly decreased levels of inflammatory cytokines such as IL-6, TNF-α, IL-1β, and MCP-1, while enhancing antioxidant activities of GSH-Px and SOD, and lowering MDA levels, indicating diminished oxidative stress. Mechanistically, these renoprotective effects of celastrol partly attributed via inhibition of the PI3K/Akt/NF-κB signalling pathway, as blocking NF-κB signalling by bortezomib resulted in similar inhibitory effects against inflammation and fibrosis.
