DON is one of the major mycotoxic contaminant of cereal grains throughout the world. The purpose of this investigation was to characterize the effects of a range of environmentally relevant doses of DON in mice exposed through a subchronic toxicological assay. Animals received 3 days per week for 4 weeks, 0.014, 0.071, 0.355 or 1.774 mg of toxin/kg b.w. All(More)
Hck, a protein-tyrosine kinase of phagocytes, is the unique member of the Src family expressed under two alternatively translated isoforms differing in their N-terminal site of acylation: p61(Hck) has an additional 21-amino acid sequence comprising a single myristoylation motif, whereas p59(Hck) N terminus has myristoylation and palmitoylation sites.

Fumonisin B1 (FB1) is a mycotoxin produced by Fusarium verticillioides, a fungus that commonly contaminates maize. In the present study, we investigated the effects of FB1 on swine peripheral blood mononuclear cells (PBMC) by measuring cell proliferation, cell cycle progression and interleukin (IL)-2 production. Forty-eight hours after treatment in vitro,(More)
Due to the broad spectrum of pesticide usages, consumers are exposed to mixtures of residues, which may have combined effects on human health. The PERICLES research program aims to test the potential combined effects of pesticide mixtures, which are likely to occur through dietary exposure. The co-exposure of the French general population to 79 pesticide(More)
Deoxynivalenol (DON) and nivalenol (NIV) are toxic Fusarium secondary trichothecene metabolites that often co-occur regularly in cereal grains. These compounds were compared for their toxicity towards C57BL/6 mice on several parameters including alteration in plasma biochemistry, immune system reactivity and hepatic drug metabolism capacity. Mice received(More)
Nivalenol (NIV) is a toxic Fusarium secondary trichothecene metabolite occurring naturally in cereal grains. In order to evaluate the no observed adverse effect level (NOAEL), we tested the effects of a large array of oral doses of this toxin for responses on plasma biochemistry, the immune system and hepatic drug metabolism in mice. C57Bl6 mice received(More)
