Malus toringoides(Rehd.) Hughes, called “Eseye (Ese),” is a traditional medicinal plant from the Tibet province of China that has proven effective in treating cardiac conditions due to its anti-inflammatory, antioxidative, and antiapoptotic properties. In this study, we explored the underlying protective mechanisms of Ese decoction in isoproterenol (ISO)-induced cardiac fibrosis (CF) and established the fact that treatment with an Ese decoction attenuated tissue injury, decreased the release of IL-1β, IL-18, TNF-α, and caspase-3, and elevated the Bax/Bcl-2 ratio in CF mice. We also found that with Ese treatment damage to the mitochondrial ultrastructure of myocardium was alleviated, and the level of reactive oxygen species was markedly diminished. Ese inhibited the expression of proteins associated with pyroptosis by the HK1/NLRP3 signaling pathway and also improved CF. Due to the anti-inflammatory, antioxidative, and antiapoptotic characteristics of Ese decoction, we found that Ese protected against ISO-induced CF, by inhibiting inflammation and pyroptosis as mediated by the HK1/NLRP3 signaling pathway.Graphical AbstractMalus toringoides(Rehd.) Hughes decoction alleviates cardiac fibrosis by inhibiting cardiomyocyte inflammation and pyroptosis. |
