Abstract
Gastric mucosal injury is the initial stage of the occurrence and development of gastric diseases. Oxidative stress and ferroptosis caused by the imbalance of redox and iron dynamics in gastric mucosal epithelial cells are present throughout the occurrence and development of gastric mucosal injury. Therefore, the inhibition of oxidative stress and ferroptosis is a potential target for the treatment of the gastric mucosal injury. Xiaojianzhong decoction (XJZ), which consists of six Chinese herbal medicines and extracts, is used for the treatment of diseases related to gastrointestinal mucosal injury; however, its specific mechanism of action has yet to be clarified. In this study, we clarified the protective effect of XJZ on gastric mucosa and revealed its underlying mechanism. We established a gastric mucosal injury model using aspirin and administered XJZ. Furthermore, we systematically evaluated the mucosal injury and examined the expression of genes related to oxidative stress, ferroptosis, and inflammation. The study found that XJZ significantly counteracted aspirin-induced gastric mucosal injury and inhibited oxidative stress and ferroptosis in mice. Upon examining SQSTM1/p62(p62)/Kelch-like ECH-associated protein 1 (Keap1)/Nuclear Factor erythroid 2-Related Factor 2 (Nrf2), a well-known signaling pathway involved in the regulation of oxidative stress and ferroptosis, we found that its activation was significantly inhibited by aspirin treatment and that this signaling pathway was activated after XJZ intervention. Our study suggests that XJZ may inhibit aspirin induced oxidative stress and ferroptosis via the p62/Keap1/Nrf2 signaling pathway, thereby attenuating gastric mucosal injury.
