. 2009 , Otto et al . 2008 ). In addition, GPR30 is expressed in oxytocin (OXT) neurones of the rat hypothalamic paraventricular nucleus (PVH) and supraoptic nucleus (SON), implicating a role for GPR30 in the fast, non-genomic actions of E 2 on OXT

possible that proportionate hyperphagia may arise from impairment of the anorexic oxytocin circuitry. Although we have yet to quantify oxytocin expression in PWS-IC del mice, a reduction in the population of parvocellular oxytocin neurons has previously

found that Sim1 mRNA level in the PVN of Mrap2 tm1a/tm1a mice was less than 50% of that observed in wild-type littermates ( Fig. 5C ). Sim1 is responsible for the late stages of the differentiation of oxytocin (Oxt), arginine vasopressin (Avp

). Additionally, in the same study, we have shown basal levels of AVP, oxytocin and CRF gene expression in the hypothalamic PVN, and pro-opiomelanocortin (the precursor for ACTH) gene expression in the anterior pituitary to be similar in V1bR KO and WT mice

AVP (and the related nonapeptide oxytocin) was found in the rat and human pancreas, suggesting that like CRH, AVP may play a local regulatory role in pancreatic function ( Amico et al . 1988 ). More recently pharmacological and gene knockout studies

an hypothesis about the possible involvement of GnIH in the post-ejaculatory refractory period after orgasm. It would be worthwhile to test this hypothesis in experimental models. Many studies have described the involvement of oxytocin and prolactin

oxytocin promoter (RO) with firefly luciferase reporter gene (LUC) hERα-RO-LUC or human ERβ-RO-LUC was cultured in medium with 5% charcoal-treated supplemented-defined bovine calf serum. For the assay, 5×10 4  cells/well were seeded into a 96-well plate and
