A novel DON-degrading aldo-keto reductase named AKR11A2 was identified from Bacillus velezensis Vel-HNGD-F2 through BlastP comparison. AKR11A2, an enzyme with a molecular mass of 34.8 kDa encoded by a 933 bp gene, exhibited optimal activity at pH 9 and 40 °C, while demonstrating remarkable thermal and alkaline stability by retaining over 90% of its activity. UPLC-MS/MS analysis revealed that the m/z of the DON degradation product was 295.1, identified as 3-epi-DON, formed through the direct isomerization of DON. Notably, zebrafish experiments demonstrated that the liver toxicity of the degradation product was significantly lower than that of DON. AKR11A2 effectively degraded 50.69% of the DON in contaminated corn, highlighting its practical application in food safety.

The results indicated that AT III alleviate the symptoms of DSS-induced colitis, reduce the disruption of intestinal epithelial barrier, and decrease FD4. Moreover, AT III inhibited the destruction of intestinal epithelial TJ structure and bacterial translocation in UC mice. AT III reversed the high levels of IL-1β and TNF-α, the decrease of occludin, ZO-1 expressions. Furthermore, AT III showed similar effects to PDTC (pyrrolidinedithiocarbamate) in ameliorating the disruption of the TNF-α-induced TEER and FD-4 disruption, MLCK protein expression, and MLC2 phosphorylation.

Further, OVA-specific IgE and IgG1 humoral immune responses, leukocytes infiltration, and histopathological alterations in tissues of the liver, kidney, thymus and spleen were analysed by ELISA and microscopic examination. Results showed that NaF and OVA administration developed clinical symptoms of food allergy, followed by dental fluorosis in the lower incisors, evidenced by Thylstrup-Fejerskov index in mice. Besides, Vitamin C supplementation, as a potential antioxidant and anti-allergic molecule effectively reduced the symptoms of food allergy, dental fluorosis, eosinophils infiltration, and histological alterations in mice which exposed to sodium fluoride and OVA allergen.
