Abstract
Objective: Chronic inflammation is a common feature in diabetes, especially when blood sugar levels are poorly controlled. This chronic low-grade inflammation can affect various organs, including the kidneys. Podocyte damage play a key role in the development of diabetic nephropathy (DN). The aim of the study was to evaluate the nephroprotective effect of Boeravinone B (BB) against streptozotocin (STZ) induced DN in rats and explore the underlying mechanism.
Materials and methods: In this experimental study, the rats received intraperitoneal injections of STZ (60 mg/kg) to induce DN. Various doses of BB (2.5, 5, and 7.5 mg/kg) were administered orally. Glucose levels, body weights, and organ weights (hepatic and renal) were assessed. Renal, histomorphological, antioxidant, hepatic, and cytokine levels were determined, as were the mRNA expression levels of JAK2 and STAT3. At end of the experimental study, the rats were sacrificed and their renal tissues were removed for histopathological assessment.
Results: BB treatment decreased glucose levels and increased body weights. This treatment suppressed hepatic weights, increased renal tissue weights, and also decreased renal parameters like uric acid, urea, bilirubin, creatinine (Cr) and, albumin. There was a decrease (P<0.001) in histomorphological parameters such as kidney hypertrophy index (KHI), mean glomerular volume (MGV), foot process fusion ratio (FPFR), and glomerular basement membrane thickness (GBMT) after treatment with BB. In addition, this treatment improved the levels of renal podocin, renal CD2- associated protein (CD2AP) and suppressed hepatic parameter levels. BB treatment (P<0.001) altered antioxidant parameters and cytokine levels, and suppressed mRNA expressions of JAK2, STAT3, RAGE, KIM-1, NAGL, and S100A8.
Conclusion: Administration of BB showed renal protective effects against STZ-induced DN in rats via the reduction of oxidative stress and inflammatory reactions.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
