The beneficial effect of fermented whey and pumpkin extract rich in carotenoids was evaluated in Jurkat cells against aflatoxin B1 (AFB1) and ochratoxin A (OTA) cytotoxicity through a proteomic approach. The functional ingredients were added into mycotoxin contaminated bread formulation, which were digestedin vitro in order to simulate human intestinal absorption. Cell cultures were exposed during 7 days to these mycotoxins dissolved in: (a) 0.1% organic solvent (DMSO), (b) an intestinal digest of bread with pumpkin individually (PID) and (c) an intestinal digest of bread with pumpkin mixed with fermented whey (PID+WF). Extracted proteins were subjected to reduction and alkylation and subsequently a tryptic digestion in order to be analysed by liquid chromatography coupled with quadrupole time of flight (LC/MS-Q-TOF). Results obtained highlighted the beneficial role of functional ingredients employed through the identification of proteins involved in several biological processes and metabolic pathways, mainly antioxidant activity, nucleosome assembly and secretory senescence phenotype. Among proteins involved in antioxidant activity, peroxiredoxin 1 and 2 stand out. Comparing the different conditions investigated, a remarkable change was observed in their expression, ranging from a repression using the standard (DMSO 0.1%), to an overexpression when treated with the functional ingredients. Similarly, after PID and PID+WF treatment, histones’ expression implicated in the metabolic pathway of nucleosome assembly, such as H2A, H2B, H2C, H3 and H4, was increased. Furthermore, the expression of protein cyclin A2, which downregulation is involved in limiting carcinogenic cells growth, was lower in presence of both functional ingredients. Based on these findings, functional ingredients can act as protectors against genomic stress caused by mycotoxins, preventing the loss of vital cell functions and paralysing the growth of carcinogenic cells.
