The effects of supraphysiological levels of testosterone on neural networks upstream of gonadotropin-releasing hormone neurons
Objective(s): Several pathological conditions are associated with hyper-production of testosterone; however, its impacts are not well understood. Hence, we evaluated the effects of supraphysiological levels of testosterone on gonadotropin-releasing hormone (GnRH) system in the hypothalamus of male rats. Also, we assessed the expression of two excitatory (kisspeptin and...
متن کاملCoexpression of gonadotropin inhibitory hormone with Agouti-related peptide in the neurons of arcuate nucleus of ewe hypothalamus
Introduction: Gonadotropin inhibitory hormone (GnIH) and Agouti-related peptide (AgRP) are orexigenic peptides expressed in the arcuate nucleus (Arc) of the hypothalamus in the ewe. In addition, effects of GnIH and AgRP on the regulation of gonadotropin releasing hormone secretion have been shown in some mammals. The objective of the present study was to investigate the coexpression of GnIH ...

15 صفحه اولIntermediary role of kisspeptin in the stimulation of gonadotropin-releasing hormone neurons by estrogen in the preoptic area of sheep brain
Introduction: The role of estrogen in the stimulation of gonadotropin-releasing hormone (GnRH) neurons is clear. These neurons do not express estrogen alpha receptors, so other mediator neurons should be present to transmit the positive feedback effect of estrogen to the GnRH neurons. Kisspeptin neurons have an important role in the stimulation of GnRH neurons, so they can be the mediator of...
