Mitochondrial proteomics profile points oxidative phosphorylation as main target for beauvericin and enniatin B mixture

2020

Abstract Beauvericin (BEA) and enniatin B (EN B) are non-legislated Fusarium mycotoxins usually found in cereal and cereal-based products all around the world. By the proteomic analysis of mitochondria enriched extracts from Jurkat cells exposed for 24 h to three concentrations of BEA:EN B (0.01–0.1–0.5 μM), a number of 1821 proteins (202 mitochondrial) were identified and relatively quantified. 340 proteins (59 mitochondrial) were statistically significant altered in our samples (Anova p-value ≤ 0.05 and fold change (FC) ≥1.5). The protein mitochondrial translational release factor 1 like (MTRF1L) was the most abundant protein in the three mycotoxin exposures studied. The mycotoxins mixtur…
