Leptin inhibits directly glucocorticoid secretion by normal human and rat adrenal glandF P Pralong
Division of Endocrinology, Diabetology and Metabolism, University Hospital, Lausanne, Switzerland
Endocrinology 139:4264-8. 1998..Therefore, leptin inhibits directly stimulated cortisol secretion from human and rat adrenal glands, and this may represent an important mechanism to modulate glucocorticoid levels in various metabolic states...
Complete hypogonadotropic hypogonadism associated with a novel inactivating mutation of the gonadotropin-releasing hormone receptorF P Pralong
Department of Medicine, University Hospital, Lausanne, Switzerland
J Clin Endocrinol Metab 84:3811-6. 1999..In conclusion, we report the first mutation of the GnRH-R gene that can induce a total loss of function of this receptor and is associated with a phenotype of complete hypogonadotropic hypogonadism...
Food-dependent Cushing's syndrome: possible involvement of leptin in cortisol hypersecretionF P Pralong
Department of Medicine, Institute of Pathology, University Hospital and Lausanne Medical School, Switzerland
J Clin Endocrinol Metab 84:3817-22. 1999..Further studies in other cases of food-dependent Cushing's syndrome, however, will be necessary to better ascertain the pathophysiological significance of this finding...
Acceleration of pubertal development following central blockade of the Y1 subtype of neuropeptide Y receptorsF P Pralong
Division of Endocrinology, Diabetology and Metabolism, Department of Medicine, Lausanne University Hospital, 1011, Lausanne, Switzerland
Regul Pept 95:47-52. 2000..They are entirely consistent with the proposed inhibition exerted by endogenous hypothalamic NPY before the onset of pubertal development. They also suggest that the Y1 subtype of NPY receptors is involved in this effect...
Neuroendocrine effects of leptinF P Pralong
Department of Medicine, University Hospital, Lausanne, Switzerland
Pituitary 4:25-32. 2001..The precise site of action and mode of regulation of the gonadotrope and somatotrope axes by leptin are reviewed...
The neuropeptide Y Y1 receptor regulates leptin-mediated control of energy homeostasis and reproductive functionsFrancois P Pralong
Division of Endocrinology, Diabetology and Metabolism, University of Lausanne Medical School, CH 1011 Lausanne, Switzerland
FASEB J 16:712-4. 2002..Results point to a crucial role for the NPY Y1 receptor in mediating the NPY pathways situated downstream of leptin actions and controlling food intake, the onset of puberty, and the maintenance of reproductive functions...
The neuropeptide Y Y1 receptor mediates NPY-induced inhibition of the gonadotrope axis under poor metabolic conditionsChristine Gonzales
Division of Endocrinology, Diabetology and Metabolism, University Hospital, Lausanne, Switzerland
FASEB J 18:137-9. 2004....
The lack of effect of insulin on luteinizing hormone pulsatility in healthy male volunteers provides evidence of a sexual dimorphism in the metabolic regulation of reproductive hormonesMarie Hélène Pesant
Service of Endocrinology, Diabetology and Metabolism, Department of Medicine, Lausanne University Hospital, Switzerland
Am J Clin Nutr 96:283-8. 2012..This link is particularly important in healthy women, in whom insulin is a positive signal for the reproductive system. In contrast, very little is known regarding this relation in men...
Insulin and NPY pathways and the control of GnRH function and puberty onsetFrancois P Pralong
Services of Endocrinology, Diabetology and Metabolism, University Hospitals of Lausanne and Geneva, Switzerland
Mol Cell Endocrinol 324:82-6. 2010....
Metformin inhibits adenosine 5'-monophosphate-activated kinase activation and prevents increases in neuropeptide Y expression in cultured hypothalamic neuronsCatherine Chau Van
Service of Endocrinology, BH 19 709, University Hospital, 1011 Lausanne, Switzerland
Endocrinology 148:507-11. 2007....
Insulin modulation of luteinizing hormone secretion in normal female volunteers and lean polycystic ovary syndrome patientsMallory Moret
Service of Endocrinology, Diabetology and Metabolism, University Hospital, University of Lausanne, Lausanne, Switzerland
Neuroendocrinology 89:131-9. 2009..This study was undertaken to further evaluate the role of insulin to modulate LH secretion in lean PCOS patients with normal insulin sensitivity and normal volunteers...
Molecular characterization and phenotypic expression of mutations in genes for gonadotropins and their receptors in humansRoberto Salvi
Service of Endocrinology, Diabetology and Metabolism, University Hospital, Lausanne, Switzerland
Front Horm Res 39:1-12. 2010..In this work, we describe briefly the known mutations in the genes for both gonadotropins and their receptors, and discuss their genotype/phenotype correlations in light of these important gender differences...
Progressive onset of adrenal insufficiency and hypogonadism of pituitary origin caused by a complex genetic rearrangement within DAX-1Roberto Salvi
Division of Endocrinology and Diabetology, University Hospital, 1011 Lausanne, Switzerland
J Clin Endocrinol Metab 87:4094-100. 2002..In vitro functional analyses confirm the absence of repressor activity exerted by such mutant protein. These studies expand the genotypic and phenotypic spectrum of DAX-1 insufficiency in humans...
Phenotypic and molecular characterization of proliferating and differentiated GnRH-expressing GnV-3 cellsVirginie Mansuy
Service of Endocrinology, Diabetology and Metabolism, University Hospital and Faculty of Biology and Medicine, 1011 Lausanne, Switzerland
Mol Cell Endocrinol 332:97-105. 2011..Moreover, the genes differentially regulated between these two different states are providing novel pathways potentially important for a better understanding of the physiology of mature GnRH neurons...
