Toxicological Mechanisms and Chemical In Fish (CYP-lab)
Short description
We are interested in physiological and molecular mechanisms behind unwanted chemical mixture effects in fish. Our focus is on key proteins in the detoxification pathway and how they are affected by individual chemicals and mixtures. We study different chemical classes—including steroid hormones, pharmaceuticals, biocides, algae toxins, and aromatic hydrocarbons—and how they interfere with the detoxification pathway in fish liver cells. We develop new approach methodologies to reduce animal toxicity experiments. One goal is to build physiological data-based models that describe and forecast synergistic effects of pollutant mixtures. We hypothesize that identifying “bottlenecks” in detoxification can lead to alternative models to assess and predict mixture effects.
