Prerequisites:
None

Academic preconditions:
The curriculum from bachelor in biology or similar is assumed known.

Course introduction
The aim of the course is to explain, at the molecular level, why some chemicals are toxic to living organisms. We will study the most important processes and cellular structures that are attacked by man-made chemicals as well as the defence mechanisms that living organisms possess.

Expected learning outcome
At the end of the course the student is expected to be able to:

Describe the biochemical pathways leading to bioactivation of selected chemicals.
Predict the metabolic fate of chemicals from their molecular structure.
Describe the molecular mechanisms behind damages to membranes, enzymes and DNA caused by selected chemicals.
Discuss the relative importance and temporal succession of toxic events in the cell.
Describe the molecular mechanisms behind damages to cellular transport of compounds and energy production caused by selected chemicals.
Discuss organ-level effects based on events on the molecular level.
Describe the molecular mechanisms behind disruption of the endocrine system by selected chemicals.
Discuss the contribution of different endocrine disrupting mechanisms to observed effects.
Describe the defence systems that organisms possess against oxidative stress, metals and lipophilic compounds.
Discuss interactions between different defence systems and the consequences of suppression and activation of sub-systems.

Subject overview
Cellular transport of xenobiotics; selective accumulation and organ specific toxicity.
Bioactivation of compounds by the P450-system, especially carcinogens.
Oxidative stress, free radicals and lipid peroxidation of membranes.
Covalent binding of xenobiotics to biological macromolecules.
Nuclear receptor mediated toxicity with special emphasis on endocrine disrupting chemicals.
The cellular energy production as a target for xenobiotics.
