Project duration01.01.2019 – 31.12.2021
The project is aimed at monitoring the extent of damage to genetic material and the induction of epigenetic changes in cultured ruminant lymphocytes after application of selected combinations of pesticides. Presence of double-strand breaks on DNA, the increase of which is associated with disruption of the integrity of the cell genome and tumour will be assessed by detection of phosphorylated histone H2AX and comet assay. As biomarkers cytogenetic markers will be used as biomarkers of early genotoxic effect: chromosome aberrations, exchanges sister chromatids and micronucleus test. The experiments will be complemented by the determination of kinetics and gene expression of some detoxifying enzymes in relation to oxidative stress and evaluation of the interaction of selected pesticides with biological macromolecules. At present, little is known about epigenetic changes induced by pesticides in livestock cells and their impact on health status. Therefore, the project will also address the identification of DNA methylation changes in some genes for metabolising enzymes. Translated with www.DeepL.com/Translator (free version)
