BACKGROUND AND OBJECTIVE: Ischemic stroke is a disease with high incidence. Astaxanthin is a functional foods with protective effects against ischemic stroke. However, the integral mechanism of astaxanthin protect ischemic stroke is not clear. The aim of this study was to investigate the mechanism of astaxanthin protect ischemic stroke by integrated network analysis.
METHODS: Middle cerebral artery occlusion model was used to establish ischemic stroke model, and ischemic stroke models were treated with 25, 45, 65 mg/kg astaxanthin for 7 days. The rats were killed 24 h after successful modeling. Integrated network analysis, molecular docking, molecular dynamics (MD) simulation, and Western blot were used to explore the astaxanthin and potential proteins related to inflammation and cell death.
RESULTS: The results of integrated network analysis indicate that astaxanthin may protect ischemic stroke through Toll like receptor signaling pathway and apoptosis pathway. The main targets involved MMP9, IL1B, IL10, Bcl2 and among others. astaxanthin has a low binding score and compact complex with PARP1, AIF, Bax, IL10, MMP9, Bcl2. In addition, astaxanthin has reduced inflammation and cell death-related proteins such as PARP1, AIF, Bax, TLR4, MMP9, IL1β and increased anti-inflammation and anti-cell death-related proteins by Bcl2 and IL10.
CONCLUSIONS: Astaxanthin can improve anti-inflammatory, anti-cell death ability after ischemic stroke. Our study provides a theoretical basis for the subsequent experimental and clinical application of astaxanthin in the treatment of ischemic stroke.
