Objective: Recently rare heterozogous AMH genetic variants have been identified in women with polycystic ovary syndrome (PCOS) that result in reduced AMH signaling. However, the exact functional mechanism remains unknown. Therefore, we have performed functional analyses to analyze the processing, secretion and signaling of these PCOS-specific AMH rare variants.Methods: Six PCOS-specific AMH variants containing mutations (V12G, P151S, P270S, P352S, P362S,...

Binge-eating disorder is the most prevalent eating disorder diagnosed, affecting three times more women than men. It is characterised by binge-eating episodes: the rapid consumption of a large amount of food, without needing the calories. The gut hormone ghrelin stimulates appetite and reward signalling, and loss of its receptor reduces binge-eating behaviour in male mice. We aimed to examine the influence of ghrelin itself on binge-eating behaviour in mice of both sexes. 5-we...

Polycystic ovary syndrome (PCOS) is a disorder associated with infertility and metabolic disturbances. Ovaries of PCOS women contain an increased number of growing follicles. Such an ovarian phenotype is also observed in mice lacking the ovary-specific growth factor anti-Müllerian hormone (AMH). To determine the interaction between ovarian and metabolic function, we studied the metabolic phenotype of mice lacking AMH signaling as a model for an altered profile in ovarian ...
