Throughout the world, some foods and feeds commonly consumed by humans and animals are inadvertently contaminated with mycotoxins. Zearalenone (ZEA) is a typical environmental/food contaminant that can cause varying degrees of damage to the body, such as reproductive toxicity, hepatotoxicity, immunotoxicity, etc. It poses a serious threat to the living environment and human and animal health. Increasing evidence shows that mycotoxin-induced organ damage may be closely related to ferroptosis. However, the mechanism of ZEA-induced liver injury is still not fully understood. Therefore, this study aimed to explore whether ZEA can trigger ferroptosis in the liver and cause liver injury. This study was conducted by establishing in vivo and in vitro ZEA exposure models. The results showed that ZEA exposure led to typical liver injury indicators. ZEA inhibited the Nrf2/keap1 antioxidant signaling pathway, aggravated the oxidative stress response, and inhibited the body's antioxidant function. Additionally, it was found that ZEA can aggravate lipid peroxidation by blocking the system Xc-/GSH/GPX4 axis, upregulating the protein expression of ACSL4, and affecting the import, storage, and export of iron ions, thereby inducing iron ion metabolism disorders. A combination of multiple factors induces ferroptosis in mouse liver and AML12 cells. Pretreatment with deferoxamine, an inhibitor of ferroptosis, can alleviate ferroptosis damage induced by ZEA, indicating the crucial role of ferroptosis in cell damage caused by ZEA. This study deeply explores the hepatic ferroptosis pathway induced by ZEA, provides a new theoretical basis for ZEA-induced hepatotoxicity, and offers new insights for exploring potential treatment strategies.
