Special Issue Information

Dear Colleagues,

Mycotoxins are natural toxicants produced by various molds as secondary metabolites whose occurrence has been reported in virtually all food and feed commodities. Currently, there are more than 400 characterised mycotoxins with various toxicological effects spanning from mild gastroenteritis to debilitating cancer diseases. Risk assessment studies have established a definite link between aflatoxins and liver cancer in humans; they were thus classified in group 1 as “carcinogenic to humans” by the International Agency for Research on Cancer (IARC). Other mycotoxins have been classified in group 2B as “possibly carcinogenic to humans” by the same organism. The co-occurrence of various mycotoxins apprears to be common in foods, which adds to the public health concerns they raise, as it may enhance individual toxicities.

Sustained efforts have been made to limit the incidence of mycotoxins in the food supply, and different approaches have been suggested. However, such an incidence is still alarming, especially in developing countries where good manufacturing and post-harvest practices are loosely implemented. The ubiquitous nature of molds and their versatility to grow and possibly produce mycotoxins under extreme conditions, the diversity of sources for food contamination with mycotoxin-producing molds, and the carry-over of some mycotoxins from feed to food of animal origin (in addition to their resistance to decontamination procedures) are some of the challenges that limit the efficacy of any approach aiming to eradicate mycotoxins from foods.

Despite the tremendous work that has been carried out on mycotoxins since the discovery of aflatoxins in 1960, further research is still needed to clarify many aspects related to the toxigenicity of mold strains, their environmental niches, and the routes of food contamination; little is as yet known about newly discovered (emerging) mycotoxins. With the new trend to develop science-based regulatory food safety standards, risk assessment plays a central role in the definition of pertainig regulations. Therefore, studies on this topic are currently encouraged to provide a clear view on the risk extent that mycototoxins pose to humans via food consumption, in order to adequately determine management measures.

This Special Issue is devoted to research articles, reviews, or mini-reviews on the occurrence of mycotoxins in foods, which compromises their overall hygienic quality and makes them unsafe for consumption. Research manuscripts on aflatoxins, their production, geographical distribution, seasonality of occurrence in foodstuffs, risk assessment studies, and related statistical data (e.g., exposure, intake, and levels of contamination) are encouraged.

Zearalenone (ZEA) is a non-steroidal estrogen mycotoxin produced by several Gibberella and Fusarium species. Accumulating evidence has indicated that ZEA strongly stimulates cell proliferation. However the detailed molecular and cellular mechanisms of ZEA-mediated induction of cell proliferation have not yet been completely explained. [...] Read more.
Zearalenone (ZEA) is a non-steroidal estrogen mycotoxin produced by several Gibberella and Fusarium species. Accumulating evidence has indicated that ZEA strongly stimulates cell proliferation. However the detailed molecular and cellular mechanisms of ZEA-mediated induction of cell proliferation have not yet been completely explained. The aim of this study was to detect the role of miRNAs in ZEA-mediated induction of cell proliferation. The effects of ZEA on cell proliferation were assessed using a cell counting kit assay and xCELLigence system. Micro-RNA sequencing was performed after treatment of TM3 cells with ZEA (0.01 μmol/L) for different time periods (0, 2, 6 and 18 h). Cell function and pathway analysis of the miRNA target genes were performed by Ingenuity Pathway Analysis (IPA). We found that ZEA promotes TM3 cell proliferation at low concentrations. miRNA sequenceing revealed 66 differentially expressed miRNAs in ZEA-treated cells in comparison to the untreated control (p < 0.05). The miRNA sequencing indicated that compared to control group, there were 66 miRNAs significant change (p < 0.05) in ZEA-treated groups. IPA analysis showed that the predicated miRNAs target gene involved in cell Bio-functions including cell cycle, growth and proliferation, and in signaling pathways including MAPK and RAS-RAF-MEK-ERK pathways. Results from flow cytometry and Western Blot analysis validated the predictions that ZEA can affect cell cycle, and the MAPK signaling pathway. Taking these together, the cell proliferation induced ZEA is regulated by miRNAs. The results shed light on the molecular and cellular mechanisms for the mediation of ZEA to induce proliferation.
