Recent investigations suggest that β-amyrin, a pentacyclic triterpenoid, could offer significant benefits with its potential antihyperglycemic and nephroprotective effects. We investigated the protective effects of β-amyrin alone and combined it with metformin, the cornerstone therapy for diabetes, using a hyperglycemic adult Zebrafish (ZF) model. The ZF were subjected to hyperglycemia by immersing them in 111 mM glucose solutions. Treatment efficacy was assessed by measuring serum glucose and insulin levels and antioxidant, ER stress, apoptosis, and proinflammatory markers. ZF kidneys were also studied for immunohistochemistry and histopathology. Results revealed that the combined treatment of β-amyrin and metformin resulted in a significant decrease (p ≤ 0.05) in blood glucose levels to 104.54 ± 1.63 mg/dL, in comparison to 388.75 ± 4.32 mg/dL in the untreated diseased control group. The reduction in hyperglycemia was more pronounced than treatment with either compound alone. Moreover, treatment with the combination restored renal function in diseased ZF, leading to significantly lower (p ≤ 0.05) serum urea (SU: 19.57 ± 1.61 mg/dL) and serum creatinine (SC: 0.56 ± 0.02 mg/dL) values compared to treatment with β-amyrin (SU:27.02 ± 0.96 mg/dL; SC: 0.7 ± 0.01 mg/dL) or metformin (SU: 24.53 ± 1.29 mg/dL; SC: 0.6 ± 0.02 mg/dL) alone. The treatment also reduced oxidative stress markers, apoptosis and ER stress markers, and proinflammatory cytokines. Histopathological analysis showed improved renal architecture with significantly lower (p ≤ 0.05) renal tubular injury scores with the combination than with individual treatment. This study provides novel insights into the combined therapeutic effects of β-amyrin and metformin in mitigating hyperglycemia-induced renal damage through key molecular pathways, highlighting a potentially effective therapeutic strategy for diabetic nephropathy. The findings hold promising translational relevance for developing combination therapies aimed at improving clinical outcomes in diabetic nephropathy patients.</p>","PeriodicalId":9023,"journal":{"name":"BMC Pharmacology & Toxicology","volume":"25 1","pages":"66"},"PeriodicalIF":2.8,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11430224/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142341170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
