Mechanisms of toxicity - Chemical interactions in fish (CYP-lab)

Research project

Short description

We are interested in the physiology and the molecular mechanisms behind adverse chemical interactions in fish exposed to mixtures of chemicals. Our project focuses on key mechanisms in detoxification pathways and how chemicals alone and in mixtures interact with these pathways in cultured fish cells. We hypothesis that by describing “bottlenecks” in chemical elimination pathways new alternative models can be developed. These models can be used to assess and forecast unwanted synergistic mixture effect between different classes of substances including steroid hormones, pharmaceuticals and aromatic hydrocarbons. We have created a new conceptual toxicokinetic model, based on experimental data from our lab.
