Abstract

Deoxynivalenol (DON) is a prevalent mycotoxin commonly detected in both human and animal diets, representing a significant health risk. Sulforaphane (SFN), a bioactive compound from Cruciferous vegetables known for its antioxidant. This study aimed to confirm SFN's protective effect against DON-induced intestinal injury and clarify its underlying molecular mechanism. In vivo, C57BL/6 male mice (n = 8/group) were treated with DON (2 mg/kg BW) and SFN (10 mg/kg BW) to assess the overall protective effects of SFN; in vitro, intestinal porcine epithelial cells (IPEC-J2) and pig intestinal organoids were treated with DON (1 μg/mL) and SFN (2 μM) to investigate the protective mechanism of SFN. Hematoxylin-eosin staining, western blot and flow cytometry were used to confirm the protective effects of SFN. RNA-seq, CETSA, ITDRF and non-targeted metabolomics was employed to investigate the mechanism of SFN supplementation. This study demonstrated that SFN significantly alleviated DON-induced intestinal toxicity: in vivo, SFN restored jejunal villus height/crypt depth and restored the balance of redox homeostasis (decreased MDA, LDH, SOD and CAT); in vitro, SFN lowered DON-induced cell Apoptosis and ROS accumulation. Mechanistically, lysosomal function was critical for SFN's protection-SFN directly targeted ATP6AP1 to enhance lysosomal acidification Moreover, ATP supplementation further potentiated this acidification and SFN's cytoprotective effect. This study identified ATP6AP1-mediated lysosomal acidification as a novel mechanism for SFN to mitigate DON-induced intestinal injury. Therefore, investigating the crosstalk between the SFN-ATP6AP1 axis and gut microbiota warrants further investigation to elucidate a broader protective mechanism.
