Assay and relationship of HT-2 toxin and T-2 toxin formation in liquid culture.
Both T-2 toxin and HT-2 toxin can be conveniently quantitated in crude extracts by using a combination of thin-layer chromatography and fluorodensitometry. This technique was used to follow the production of these toxins by liquid cultures of Fusarium poae (NRRL 3287). T-2 toxin was produced prior to HT-2 toxin and hexadeuterio-T-2 toxin was converted by the culture to trideuterio-HT-2 toxin.
متن کاملMetabolism of HT-2 Toxin and T-2 Toxin in Oats
The Fusarium mycotoxins HT-2 toxin (HT2) and T-2 toxin (T2) are frequent contaminants in oats. These toxins, but also their plant metabolites, may contribute to toxicological effects. This work describes the use of 13C-assisted liquid chromatography-high-resolution mass spectrometry for the first comprehensive study on the biotransformation of HT2 and T2 in oats. Using this approach, 16 HT2 and...
متن کاملMetabolism of the Fusarium Mycotoxins T-2 Toxin and HT-2 Toxin in Wheat
To investigate the metabolic fate of HT-2 toxin (HT2) and T-2 toxin (T2) in wheat (Triticum aestivum L.), an untargeted metabolomics study utilizing stable isotopic labeling and liquid chromatography-high resolution mass spectrometry was performed. In total, 11 HT2 and 12 T2 derived in planta biotransformation products were annotated putatively. In addition to previously reported mono- and digl...
متن کاملT-2 toxin and its metabolite HT-2 toxin combined with insulin-like growth factor-I modify progesterone secretion by porcine ovarian granulosa cells.
The aim of this study was to examine the effect of A-trichothecenes T-2 and HT-2 toxins combined with insulin-like growth factor I (IGF-I) on the release of steroid hormone progesterone (P4) by porcine ovarian granulosa cells (GCs). The cells were incubated without (control) or with treatments of A-trichothecenes T-2 (100 and 1000 ng/mL)/ HT-2 (100 and 1000 ng/mL) combined with IGF-I (1, 10 and...
متن کاملEffects of T-2 Toxin on Cytokine Produc-tion by Mice Peritoneal Macrophages and Lymph Node T-Cells
Background: T-2 toxin is a mycotoxin of type A trichothecenes produced by several fungal genera such as Fusarium species. Mycotoxins can affect both cell mediated and humoral immune compartments. Objective: The purpose of this study was to investi-gate the effect of T-2 toxin on cytokine production by mouse peritoneal macrophages and lymph node T cells. Methods: Mouse peritoneal macrophages and...
