A wide variety of contaminants are ingested through food, among them the pro-carcinogenic polycyclic aromatic hydrocarbon benzo[a]pyrene (BP) that is resorbed and partially metabolized in the enterocytes of the small intestine. Previous in vitro studies have revealed that BP phenols are excreted as Phase II metabolites including glucuronides and sulfates.(More)
The ingestion of seafood contaminated with the marine biotoxin okadaic acid (OA) can lead to diarrhetic shellfish poisoning with symptoms like nausea, vomiting and abdominal cramps. Both rat and the human hepatic cytochrome P450 monooxygenases (CYP) metabolize OA. However, liver cell toxicity of metabolized OA is mainly unclear. The aim of our study was to(More)
Human primary hepatocytes represent a gold standard in in vitro liver research. Due to their low availability and high costs alternative liver cell models with comparable morphological and biochemical characteristics have come into focus. The human hepatocarcinoma cell line HepG2 is often used as a liver model for toxicity studies. However, under(More)
