Zearalenone (ZEN) and its derivative, zearalanone (ZAN), are endocrine disruptive mycotoxins produced by Fusarium species. We investigated the human placental metabolism of ZEN and ZAN in vitro in JEG-3 cells, human term placental subcellular fractions and recombinant enzymes. Human placental enzymes were capable of metabolizing ZEN and ZAN to their primary OH-metabolites which have higher affinity...
Previous studies have indicated that aromatase (CYP19A1) is involved in the metabolism of aflatoxin B1 (AFB1). We hypothesized that exposure to AFB1 contaminated food during pregnancy could disrupt the normal production of steroid hormones in placenta. We examined the capability of AFB1 exposure to disrupt CYP19A1 expression as a putative endocrine disrupter, and to investigate the metabolism of AFB1...
