Mechanisms of potential toxic effects of bisphenol A on the endocrine system
Zachardová, Lenka ; Novotný, Jiří (advisor) ; Rupert, Marian (referee)
Bisphenol A (BPA) has already been used in the chemical industry for several decades. Since that time, a huge amount of in vitro and in vivo studies have been accumulated summarizing the molecular mechanisms of BPA causing disruption in endocrine homeostasis in all kinds of biological models. It enters the body from external environment; however, the main source of penetration is through consumption of food and liquids that are in contact with materials containing the mentioned xenoestrogen. The hydroxyl group within BPA phenol ring enables binding to transmembrane G- protein-coupled estrogen receptors and a number of nuclear receptors affecting hormonal system and resulting in alterations in signalling pathways. BPA induces oxidative stress and interferes with regulation factors functions at gene, cell and tissue level. Disruptive effects are associated with developmental, reproductive, cardiovascular, immune and neurobiological disorders. This thesis is aiming to sum up existing findings about the molecular mechanisms of BPA toxicity in the endocrine system mainly using Mus musculus model. Keywords: BPA, endocrine system, nuclear receptors, GPER, oxidative stress.
