In this work, the cytotoxicity of Beauvericin (BEA), lutein (LUT), zeaxanthin (ZEAX) and goji berries extract (GBE) rich in carotenoids, was investigated, as well as cytoprotective effects of these carotenoids against BEA induced-cytotoxicity on Caco-2 cells. Cytotoxicity was carried out using MTT and protein content (PC) assays during 24 and 48 h of exposure. Only BEA showed cytotoxic effect obtaining a reduction in cell proliferation range from 6.5 to 92.8%. Simultaneous combination of LUT and ZEAX with BEA slightly increased cell proliferation compared to BEA tested alone. LUT, ZEAX and GBE showed cytoprotective effects against cytotoxicity induced by BEA on Caco-2 cells. Pre-treatment assays showed the highest cytoprotection effect at the highest dose of BEA assayed (2.5 μM) in 29%, 31% and 35% for LUT, ZEAX and LUT + ZEAX, respectively; GBE showed a cytoprotection of 20%, for the same dose of BEA. The interaction between LUT, ZEAX and BEA studied by means of CI-isobologram method showed a synergism and antagaonism effect for all the combinations tested. These findings highlight that food containing high level of carotenoids, as goji berries, could contribute to reduce the toxicological risk that natural contaminant as BEA mycotoxin in diet can produce to the humans.
