MEIS3 is repressed in A549 lung epithelial cells by deoxynivalenol and the repression contributes to the deleterious effect OAK
Toyotome, Takahito; Takahashi, Hiroki; Kamei, Katsuhiko.
Deoxynivalenol (DON) is an important Fusarium toxin of concern for food safety. The inhalation of powder contaminated with DON is possible and may cause lung toxicity. In this study, we analyzed the gene expression profile of A549 cells treated for 24 hr with 0.2 µg/mL DON by microarray analysis. In total, 16 genes and 5 noncoding RNAs were significantly affected by DON treatment. The repression of B3GALT4, MEIS3, AK7, SEMA3A, KCNMB4, and SCARA5 was confirmed by quantitative PCR. We investigated the DON toxicity on A549 cells that exogenously expressed these 6 genes. The result indicated that A549 cells that transiently expressed MEIS3 were tolerant to the deleterious effects of DON. Our data show that DON affected the expression of genes with various...

The application of PCR in the detection of mycotoxigenic fungi in foods BJM
Konietzny,Ursula; Greiner,Ralf.
It is estimated that 25 to 50% of the crops harvested worldwide are contaminated with mycotoxins. Because of the toxic and carcinogenic potential of mycotoxins, there is an urgent need to develop detection methods that are rapid and highly specific. The highly advanced physico-chemical methods for the analysis of mycotoxins in use, have the disadvantage that highly sophisticated clean-up and/or derivatization procedures must be applied. An alternative could be the detection of the mycotoxigenic moulds themselves, especially as molecular techniques have been introduced recently as powerful tools for detecting and identifying fungi. PCR methods for the detection of aflatoxigenic Aspergilli, patulin-producing Penicillum and trichothecene- as well as...
