Proteomics Analysis of the Protective Effects of Hesperetin on Coronary Artery injury in Streptozotocin-Induced Type 1 Diabetic Rats

Background: Type 1 and type 2 diabetes both cause damage to the cardiovascular system. Hesperetin, a medicinal product found in foods, has been shown to have various cardioprotective effects. However, the effects of this compound on diabetes-related cardiovascular damage have not been evaluated.Methods: In this study, we aimed to investigate the protective effects of hesperetin on the coronary artery in diabetic rats and to explore its effects on the changes in critical proteins in the coronary artery using proteomics analysis. Results: Hesperetin alleviated coronary artery injury and modulated the expression of various proteins, including S100A8 and S100A9, which functioned in Toll-like receptor 4 binding, Toll-like receptor binding, and RAGE receptor binding. Pathways altered by hesperetin included type I diabetes mellitus, cell adhesion molecules, antigen processing and presentation, and interleukin-17 signaling pathway. Conclusions: In this study, we constructed a protein map of SD rats with type 1 diabetes treated with hesperetin, and found significant changes in three important proteins, S100A8, S100A9 and KNG1.Our findings provided important insights into further studies of the cardiovascular protective effects of hesperetin.
