Deoxynivalenol treatment with 10,000 ppm for 2 h

ABSTRACT: The number and type of synthetic chemicals that are being produced worldwide continues to increase significantly. While these industrial chemicals provide numerous benefits, there is no doubt that some have potential to damage the environment and health. Toxicity must be evaluated and use must be carefully controlled and monitored in order to minimize potential damage. DNA microarray technology has become an important new technique in toxicology. We are using the yeast Saccharomyces cerevisiae as a model organism for toxicological study because it is a simple, fast-growing eukaryote that has been thoroughly characterized. In order to evaluate toxicity by newly synthesized or mixture chemicals, toxicity-induced gene expression alteration profiles by known chemicals should be collected. A lethal effect of a certain kind of mycotoxin is weak to yeast. The amount of exposure to yeast used the maximum dissolution density for afratoxin DON (Deoxynivalenol, CAS; 51481-10-8) (10,000 ppm, IC70）. Because the data that was able to be trusted was not obtained, it is not possible to have analyzed toxicity. Keywords: stress response

Yeast genomic expression patterns in response to deoxynivalenol

Project description:The assessment of toxicity about deoxynivalenol (DON) using yeast gene expression comparison analysis. Two yeast strains, parental BY4743 and PTC1 mutant, were used for this study. SDS was used to raise the penetration of the yeast cell membrane. Keywords: stress response Four conditions are compared with three replicates each. Each of the two strains was grown in either 0.01% SDS-containing YPD media or 0.01% SDS-containing YPD media with 25 ppm of deoxynivalenol.

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

In order to evaluate toxicity by newly synthesized or mixture chemicals, toxicity-induced gene expression alteration profiles by known chemicals should be collected. In our study, cells need to be exposed with same experimental cellular condition, semi lethal (IC50), respectively. In the case of chloroacetaldehyde (CAS; 107-20-0), the exposure dose was decided as 25 ppm by growth curve with continuously diluted exposure. Chloroacetaldehyde is one of the toxic gases and vapors. This substrate is suspected to be respiratory toxicant and skin or sense organ toxicant. Keywords: stress response
