The "omics" is a concept of biological disciplines that globally characterizes and quantifies biomolecules involved in the key functions of an organism. The "omics" methods are used e.g. in molecular epidemiology, where they help to evaluate potential biomarkers that identify the impact of environmental factors for human health. In this thesis, the "omics" methods were applied in samples collected from newborns born in localities of the Czech Republic mostly differing by pollution levels from industrial sources. The principal aim was to determine whether environmental changes during prenatal development can affect gene expression and its regulation in newborns. The thesis further aimed to evaluate the level of air pollution at the time of biological samples collection. Using the whole genome approach, differentially expressed genes (DEGs) in newborns from districts Karvina and Ceske Budejovice (CB) were identified. In a pilot study of a small group of newborns from districts Most and CB, differentially methylated CpG sites in DNA were assessed. These sites attenuate gene activity and could be responsible for long-term changes at the genetic level. Finally, the aim was to find differentially expressed small non-coding RNA (DE miRNA) in newborns from Most and CB. Samples of umbilical cord blood from...
