The use of BEAS-2B cell line for micronucleus assay in genetic toxicology
 Červená, Tereza ; Rössner, Pavel (advisor) ; Rubeš, Jiří (referee)
This thesis deals with the application of BEAS-2B cell line for micronucleus assay in genetic toxicology. It is divided into two main parts: a) theoretical introduction to the analysis and search for suitable models for testing the impact of air pollution and manufactured nanoparticles, b) practical part that describes the results of micronuclei induction by polycyclic aromatic hydrocarbons (PAHs), extractable organic matter (EOM) from diesel exhaust particles obtained from emissions of three types of fuel and engineered nanoparticles. BEAS-2B cell line is a nonmalignant human model of lung epithelium which seems to be suitable for micronucleus assay. This assay is commonly used for determining the genotoxicity of various substances to wide variety of cell cultures and also in human studies. In this thesis, the following substances were tested: benzo[a]pyrene, 3-nitrobenzanthrone and 1-nitropyrene as carcinogenic PAHs commonly found in polluted air; EOMs from exhaust particles of 100 % diesel fuel, a blend of diesel fuel and 30 % of biodiesel, 100 % biodiesel and two types of engineered nanoparticles (TiO2 and Ag). The cells were treated with the compounds for 28, 48 and 72 hours. The results confirm the suitability of BEAS-2B cell line as a model for testing the genotoxicity of substances under...
