- Abstract: Objective. To explore the oxidative stress and inflammatory mechanisms of resveratrol intervention in myocardial ischemia-reperfusion injury (MIRI). Methods. The potential targets of resveratrol were predicted by PharmMapper. The MIRI genes were collected by Online Mendelian Inheritance in Man (OMIM), GeneCards is used to collect related disease genes, and String is used for enrichment analysis. Animal experiments were then performed to verify the systematic pharmacological results. Hematoxylin-eosin (HE) staining was used to observe myocardial damage. The levels of serum interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α) in each experimental group were detected. The protein and mRNA expressions of Toll-like receptor 4 (TLR4), nuclear factor-kappa (NF-κB) p65, IL-1β, IL-6, and TNF-α in rat myocardial tissue were measured. Results. The results of systematic pharmacology showed that insulin resistance, FoxO signaling pathway, adipocytokine signaling pathway, insulin signaling pathway, PI3K-Akt signaling pathway, ErbB signaling pathway, T-cell receptor signaling pathway, peroxisome proliferator-activated receptors (PPAR) signaling pathway, Ras signaling pathway, TNF signaling pathway, and so on were regulated to improve MIRI. The results of animal experiments showed that the myocardial cells of the sham operation group were arranged in fibrous form, and the myocardial ischemia-reperfusion injury group had obvious cell morphology disorder. Compared with the MIRI group, the resveratrol group had a certain degree of relief. Compared with the MIRI group, serum IL-1β, TNF-α, and IL-6 in the resveratrol group was significantly reduced (P < 0.05), and myocardial tissue TLR4, NF-κB p65, IL-1β, IL-6, and TNF-α mRNA and protein expressions were significantly reduced (P < 0.05). Conclusion. Resveratrol can effectively improve MIRI, and its mechanism may be related to antioxidative stress and anti-inflammatory. [ABSTRACT FROM AUTHOR]
