Transcriptome analysis of Caco-2 Cells upon deoxynivalenol and its acetylated exposure

ABSTRACT: Deoxynivalenol (DON), 3-acetyldeoxynivalenol (3-ADON) and 15-acetyldeoxynivalenol (15-ADON) are type B trichothecenes and are major pollutants in food and feed products. Although the toxicity of DON has been well documented, the information of toxicity of its acetylated derivative remains incomplete. To acquire more detailed insight in 3-ADON and 15-ADON, Caco-2 cells under 0.5 µM DON, 3-ADON and 15-ADON treatment for 24 h were subjected to RNA-seq analysis. In the present study, 2656, 3132 and 2425 differentially expressed genes (DEGs) were selected respectively and were enriched utilizing KEGG and GO database. The upregulation of ataxia-telangiectasia mutated kinase (ATM), WEE1 homolog 2 (WEE2) and downregulation of proliferating cell nuclear antigen (PCNA), minichromosome maintenance (MCMs), cyclin dependent kinase (CDKs), E2Fs indicate that the three toxins induced DNA damage, inhibition of DNA replication and cell cycle arrest in Caco-2 cells. Apart from these, the upregulation of sestrin (SENEs) and NEIL1 implied that the reason of DNA damage may attribute to oxidative stress. Our study provides an insight in the toxic mechanism of 3-ADON and 15-ADON.

Ribosome quality control is a central protection mechanism for yeast exposed to Deoxynivalenol and Trichothecin

Project description:Trichothecenes, like deoxynivalenol (DON) are secondary metabolites of Fusarium species, and are major pollutants in cereal food and feed products. They inhibit eukaryotic protein synthesis, however with only partly resolved consequences for the cellular homeostasis. Here we report a systematic functional investigation of the effects of DON on exponential phase growing yeast cells using either short doses of DON or continuos treatment with DON.

Comparative study of deoxynivalenol and 15-acetyldeoxynivalenol on gene expression in the human cell line Caco-2

Project description:To screen cellular effects on Caco-2 cells by deoxynivalenol (DON) and 15-acetyldeoxynivalenol (15ADON), toxin-treated Caco-2 cells were analyzed by DNA microarray. Exposure to either toxin induced up- or downregulation of genes in Caco-2 cells. Upregulation of 1290 and 3238 genes was observed for the DON- and 15ADON-treated groups, respectively, after a 60-min incubation period. This represented a greater than 1.5-fold change relative to the 0-min exposure (control) group. Five hundred and sixty-one genes showed a 1.5-fold upregulation in the both the DON- and 15ADON-treated groups. Similarly, 13 genes and 105 genes were upregulated with a log2 ratio > 2 (4-fold change) in the DON- and 15ADON-treated groups, respectively. The most remarkable gene upregulation corresponded to the inflammatory chemokine, IL-8, which showed a greater than 4-fold upregulation in response to both treatments.

Impact of biomechanical stimulation in the toxicity of deoxynivalenol in A431 cells: impairment of “dynamic” cell functions

Project description:Morphology together with the capability to respond to surrounding stimuli are the key elements governing the spatial interaction of a living cell with the environment. In this respect, biomechanical stimulation can trigger significant physiological cascades that can potentially modulate or interact with toxicity. Deoxynivalenol (DON, vomitoxin) is one of the most prevalent mycotoxins produced by Fusarium spp. and it was used to explore the delicate interaction between biomechanical stimulation and cytotoxic processes in A431 cells. In fact, in addition of being a well-known food contaminant, DON is becoming a relevant toxin also for other organ systems. The combination between biomechanical stimulation and the mycotoxin revealed how DON can impair crucial functions like cellular morphology and lysosome trafficking at concentrations far below those known to be cytotoxic in routine toxicity studies. Moreover, sub-toxic concentrations of DON (0.1-1 μM) impaired the capability of A431 cells to respond to a biomechanical stimulation that normally sustains trophic effects in this cell line. Ultimately, the effects of DON (0.1-10 μM) were partially modulated by the application of uniaxial stretching (0.5Hz, 24h, 15% deformation) suggesting a deep cross-talk between the cytotoxic potential of the mycotoxin and the biomechanical stimulation.

Gene Regulation of Intestinal Porcine Epithelial Cells IPEC‑J2 is Dependent on the Site of Deoxynivalenol Toxicological Action

Project description:Here we analysed different mechanisms of apical and basolateral deoxynivalenol (DON) toxicity reflected in the gene expression. We used the jejunum derived, polarized intestinal porcine epithelial cell line IPEC‑J2 as an in vitro cell culture model. Luminal and blood stream DON intoxication was mimicked by a DON application from the apical or basolateral compartment of ThinCert® membrane inserts for 72 h.

Deoxynivalenol affects the gene expression of A549 lung epithelial cells

Project description:Deoxynivalenol (DON) is an important Fusarium toxin of concern for food safety. The inhalation of powder contaminated with deoxynivalenol is possible and may cause lung toxicity. In this study, we investigated the gene expression profile of A549 cells treated with 0.2 microg/mL deoxynivalenol by microarray analysis. In total, 16 genes and 5 noncoding RNAs were significantly affected by deoxynivalenol treatment. 4 samples; 2 samples from nontreated cells and other 2 samples from 0.2 microg/mL DON-treated cells for 24 hours

Transcriptomic fingerprint of the type B trichothecene mycotoxins on the intestine

Project description:We employed whole genome gene expression analysis to characterize the intestinal exposure to 5 closely related food contaminants belonging to the type B trichocene mycotoxins groups The few data available on fusarenon-X (FX) do no support derivation of health-based guidance values for this mycotoxin, although preliminary results suggest higher toxicity compared to other regulated trichothecenes. Using histo-morphological analysis and whole-transcriptome profiling, the present study was designed to get a global view of intestinal alterations induced by FX. The well-described trichothecene deoxynivalenol (DON) served as a benchmark. FX exposure induced more severe intestinal histological alterations compared to DON. Intestinal inflammation was the hallmark of the molecular toxicity of DON, but also of FX. The dose-response analysis for FX revealed that benchmark doses for up-regulation of key-inflammatory genes expression were 4 to 45-fold higher than the previously reported ones for DON. Transcriptome analysis revealed that both mycotoxins down-regulated PPAR and LXR-RXR signaling pathways controlling lipid metabolism. Interestingly, several pathways including VDR/RXR activation, ephrin receptor signaling, and GNRH signaling were specific to FX and thus, discriminate the intestinal transcriptomic fingerprint of the two mycotoxins. Altogether, these results demonstrate that FX induces a more potent intestinal inflammation than DON. This study also reveals specific FX-targeted pathways, indicating that the toxicity of DON cannot serve as a benchmark for FX, and that toxicity evaluation of each trichothecene should be conducted separately.
