In vivo formation of N-acyl-fumonisin B1.
Münster, Germany. In Mycotoxin Res, Feb 2015
The hydrolyzed form of FB1 (HFB1) also occurs in foods and is metabolized by rats to compounds collectively known as N-acyl-HFB1 (also known as N-acyl-AP1).
Ca²⁺-regulated secretory granule exocytosis in pancreatic and parotid acinar cells.
Madison, United States. In Cell Calcium, 2014
Studies indicate the early phase is triggered by Ca(2+) and involves the SG proteins VAMP2 (vesicle associated membrane protein2), Ca(2+)-sensing protein synatotagmin 1 (syt1) and the accessory protein complexin 2. The molecular details for regulation of VAMP8-mediated SG exocytosis and the prolonged phase of secretion are still emerging.
Fumonisin intake of the German consumer.
München, Germany. In Mycotoxin Res, 2008
HFBs (mostly HFB1) were frequently found in processed cereals such as corn flakes, but in relatively low concentrations.
Effect ofin vitro digestion on fumonisin B1 in corn flakes.
Ottawa, Canada. In Mycotoxin Res, 2007
After incubation of the samples with gastrointestinal tract solutions simulating saliva plus stomach and duodenal juices, chyme was analysed for FB1, hydrolyzed FB1 (HFB1) and partially hydrolyzed fumonisin B1 (PHFB1).
[Formation of Fumonisin artefacts in thermal treated food].
Würzburg, Germany. In Mycotoxin Res, 2001
In model experiments FB1, hydrolyzed fumonisin B1 (HFB1) and N-tert-butoxycarbonyl-fumonisin B1 (N-BOC-FB1) were heated with D-glucose, respectively, and samples were analyzed by liquid chromatography/electrospray ionization-tandem-spectrometry (HPLC-MS/MS).
