Abstract
- T-2 toxin, a highly toxic type A trichothecene, is a secondary fungal metabolite produced by various Fusarium species. The consumption of food and feed contaminated with T-2 toxin is a major factor contributing to growth retardation, posing significant risks to both human and animal health. However, the specific targets and mechanisms that mitigate T-2 toxin-induced growth retardation remain unclear. In this study, transcriptomic analysis was employed to identify key differentially expressed genes associated with the alleviation of T-2 toxin-induced growth retardation. Peroxiredoxin 4 (PRDX4), a gene linked to oxidative stress and apoptosis, was found to be one of the most downregulated in T-2 toxin-treated GH3 cells, an in vitro model of growth retardation. The experiments demonstrated that T-2 toxin significantly increased reactive oxygen species’ production, apoptosis, and cell cycle arrest while reducing the activity of antioxidant enzymes (superoxide dismutase and glutathione peroxidase) and PRDX4 expression in GH3 cells. Furthermore, PRDX4 silencing exacerbated T-2 toxin-induced oxidative stress and apoptosis, whereas PRDX4 overexpression effectively mitigated these effects. These findings highlight the protective role of PRDX4 in counteracting T-2 toxin-induced oxidative stress and apoptosis, suggesting that PRDX4 can serve as a therapeutic target for the treatment of T-2 toxin-induced growth retardation.
