Abstract
Zearalenone (ZEA) is one of the common mycotoxins in feeds. ZEA and its metabolites have estrogen-like activity and can competitively bind to estrogen receptors, causing reproductive dysfunction and damage to reproductive organs. The toxicity mechanism of ZEA mainly inhibits the antioxidant pathway and antioxidant enzyme activity, induces cell cycle arrest and DNA damage, and blocks the process of cellular autophagy to produce toxic effects. In animal husbandry practice, when animals ingest ZEA-contaminated feed, it is likely to lead to abortion in females, abnormal sperm viability in males with inflammatory reactions in various organs, and cancerous changes in the reproductive organs of humans when they ingest contaminated animal products. In this paper, we reviewed in detail how ZEA induces oxidative damage by inducing the generation of reactive oxygen species (ROS) and regulating the expression of genes related to oxidative pathways, induces germ cell apoptosis through the mitochondrial and death receptor pathways, and activates the expression of genes related to autophagy in order to induce cellular autophagy. In addition, the molecular detoxification mechanism of ZEA is also explored in this paper, aiming to provide a new direction and theoretical basis for the development of new ZEA detoxification methods to better reduce the global pollution and harm caused by ZEA.
