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 mixture exposure induced concentration dependent changes at mitochondrial proteins levels that mainly involve inner and outer membrane complexes, Electron Transport Chain (ETC) and ribosomes. These results showed alteration of proteins levels related to oxidative phosphorylation, metabolic and neurodegenerative diseases related pathways.
