Molecular Toxicology - practice

Thematik

In the practices, the students will carry out laboratory experiments involving methods used for in vitro toxicity testing. On prokaryotic and eukaryotic cells, including cells of animal and human origin, they examine the cyto- and genotoxic effects of xenobiotics of toxicological relevance (e.g. mycotoxins, metal ions, and enzyme inducers) and of UV radiation; they analyze the binding of chemicals (e.g. ochratoxin A) to human albumin, and the effects of some drugs on the expression of cytochrome P450 (CYP) genes. The students will be acquainted with the principles of the methods used, the mechanisms of action of the toxicants studied, the details of the experimental techniques, as well as the statistical analysis, presentation and interpretation of the experimental results. The laboratory work will be carried out in an interactive fashion. The students will perform the experiments jointly according to a detailed protocol previously provided for them.

Obligatorische Literatur

Vom Institut veröffentlichter Lehrstoff

A detailed description of each practice (handout) will be available for the students on Neptun in advance of each practice. The handout will explain the principle of the methods, characterize the toxicants to be tested, describe the necessary reagents and eqipment, the steps of the experiments (protocol), the presentation, statistical analysis and evaluation of the the results. The students are expected to review the handout thoroughly before taking part on the practice.
