Epigenetic inheritance influencing the behavior of future generations and its reversibility during ontogenesis
 Freisingerová, Kateřina ; Landová, Eva (advisor) ; Švorcová, Jana (referee)
The aim of this work is to focus on possible mechanisms of transmission of changes that are conditioned by epigenetic modifications that could affect specific behaviour and phenotype in offspring. The inheritance can be channeled through both maternal and paternal lineages. It can be divided into two distinct groups of transmission, namely intragenerational and transgenerational. This work mainly focuses on the possible mechanisms of transgenerational inheritance. Epigenetic mechanisms leading to changes in the phenotype of an organism rely on influencing the regulation of DNA reading. This occurs at several levels such as DNA methylation, chemical modifications such as acetylation and other post-translational modifications, and most importantly non-coding RNA molecules. Today, countless studies are trying to explain these molecular processes mediated by environmental influences. Well known are maternal care, chemicals, or traumatic experiences. There are examples of traumatic environmental influences in which physiological changes in HPA axis regulation can be observed with consequent changes in the expression of genes for depressive and anxiety phenotypes. Most of the experiments focusing on epigenetic transmission are predominantly conducted in mouse or rat models. However, there are also...
