Reduction of Fumonisin Toxicity by Extrusion and Nixtamalization (Alkaline Cooking).

Journal of Agricultural and Food Chemistry, 2017
Fumonisins are mycotoxins found in corn. They are toxic to animals and cause cancer in rodents and neural tube defects in LM/Bc mice. Reducing their concentrations in corn-based foods is therefore desirable.

Immunochemical Methods for Fumonisins

1996
Both monoclonal and polyclonal antibodies have been raised against fumonisins (Fm) and the hydrolyzed toxin in several laboratories. They have been used in several immunoassays and can detect 5 to 5000 ng of FmB1/mL in a "clean" standard solution. However, sample matrices still give severe interferences.

Targeting Fumonisin Biosynthetic Genes

2016
The fungus Fusarium is an agricultural problem because it can cause disease on most crop plants and can contaminate crops with mycotoxins. There is considerable variation in the presence/absence and genomic location of gene clusters responsible for synthesis of mycotoxins and other secondary metabolites among species of Fusarium.

Induction of apoptosis in cultured human proximal tubule cells by fumonisins and fumonisin metabolites

Mycotoxin Research, 2001
It is well-known that fumonisin B1 (FB1) stimulates apoptosis in a variety of cell types and tissues but the apoptotic potential of other fumonisins and fumonisin metabolites has not been investigated. In our studies we exposed human proximal tubule-derived cells (IHKE cells) to FB1, fumonisin B2 (FB2), hydrolyzed fumonisin B1 (HFB1) and N-palmitoyl ...

Fumonisin Toxicity and Metabolism Studies at the USDA

1996
Fumonisins are responsible for many of the toxic effects of the common corn fungus, Fusarium moniliforme. They are acute renal and liver toxins in rats, and have tumor promoting activity. Fumonisin B1 is poorly absorbed, rapidly excreted, and persists in small amounts in the liver and kidney. Fumonisins are specific inhibitors of ceramide synthase, and

Mechanistic Insight into the Biosynthesis and Detoxification of Fumonisin Mycotoxins.

ACS Chemical Biology, 2016
Fumonisins, notably FB1, FB2, FB3, and FB4, are economically important mycotoxins produced by a number Fusarium sp. that occur on corn, rice, and sorghum as well as by Aspergillus sp. on grapes.

[37] Isolation and characterization of fumonisins

2000
Publisher Summary Fumonisins B 1 (FB 1 ), B 2 (FB 2 ), B 3 (FB 3 ), and B 4 (FB 4 ) are mycotoxins produced by Fusarium moniliforme Sheldon, a common fungal contaminate found in corn (Zea mays L.) and other cereal grains. A closely related species, Fusarium proliferatum, also produces fumonisin mycotoxins on corn.

Fumonisin mycotoxins in human hair

Biomarkers, 2003
This study shows for the first time the accumulation of fumonisin mycotoxins in human hair of population clusters exposed to contaminated maize, and thus the feasibility of human hair analysis for the assessment of past fumonisin exposure. Composite hair samples were obtained from the Bizana, Butterworth and Centane districts within the Transkei region

Molecular characterization of black Aspergillus species from onion and their potential for ochratoxin A and fumonisin B2 production.

Foodborne pathogens and disease, 2015
Onion bulbs can become contaminated with various molds during the storage period, the most important causal agents being black aspergilli (Aspergillus section Nigri).

Fumonisin Toxicity and Sphingolipid Biosynthesis

1996
Fumonisins are inhibitors of sphinganine (sphingosine) N-acyltransferase (ceramide synthase) in vitro, and exhibit competitive-type inhibition with respect to both substrates of this enzyme (sphinganine and fatty acyl-CoA). Removal of the tricarballylic acids from fumonisin B1 reduces the potency by at least 10 fold; and fumonisin A1 (which is ...
