It plays a significant role in the pathogenesis of insulin resistance, a condition characterized by impaired insulin signaling and elevated blood glucose levels. Atorvastatin is a widely prescribed statin that regulates cholesterol levels by inhibiting HMG-CoA reductase. Recent studies have suggested that atorvastatin may also impact insulin resistance through the modulation of SREBP1 expression. The DDHA1 (dimethylarginine dimethylaminohydrolase 1) and ADMA (asymmetric dimethylarginine) pathway is an important component of the nitric oxide system and contributes to the development of insulin resistance. This study aims to investigate the role of SREBP1 in modulating the expression of DDHA1 and ADMA in atorvastatin-treated insulin-resistant cells.Methods:This study will use rat insulinoma cells with insulin resistance induced by a high-glucose diet. The cells will be treated with atorvastatin, and changes in SREBP1 expression levels will be measured. DDHA1 and ADMA levels will be quantified through qPCR and ELISA. The data will be analyzed using ANOVA and Bonferroni's post hoc test to determine statistically significant differences between atorvastatin-treated cells and control cells.Expected Results:In this study, we expect atorvastatin treatment to increase SREBP1 expression levels in insulin-resistant cells. We anticipate that this upregulation will lead to increased DDHA1 expression and decreased ADMA levels. These findings would suggest that atorvastatin may improve insulin resistance by modulating the DDHA1/ADMA pathway via SREBP1.Conclusion:精品文档---下载后可任意编辑This study aims to shed light on the potential role of SREBP1 in atorvastatin-mediated improvements in insulin resistance. By elucidating the mechanisms through which atorvastatin impacts lipid and cholesterol metabolism as well as insulin resistance, this work may provide valuable insight into the development of novel treatments for metabolic disorders.
