Xenohormones and oral homeostasis : impact on taste preferences and salivary glands

2012

Oral homeostasis strongly influences taste perceptions. It depends on a healthy oral epithelium and salivary gland secretions, which are both regulated by sex hormones. The aim of this thesis was to identify the effect of an oral exposure to Bisphenol A, a food packaging and dental sealer component, and of a soy-diet containing phytoestrogens on oral homeostasisTwo experiments were conducted in adult rats: a dose-response study of BPA (5μg 12.5 mg / kj / day), and a study about the impact of a soy-diet on the BPA disrupting effects. By using gustation choice tests, and histological and qPCR-TR molecular approach, we identify for the first time an action of BPA on dry mouth. We found that BP…
