Social regulation of gene expression in the hypothalamic-pituitary-gonadal axis.

چکیده
Reproduction is a critically important event in every animals' life and in all vertebrates is controlled by the brain via the hypothalamic-pituitary-gonadal (HPG) axis. In many species, this axis, and hence reproductive fitness, can be profoundly influenced by the social environment. Here, we review how the reception of information in a social context causes genomic changes at each level of the HPG axis.

Effects of Crocin on The Pituitary-Gonadal Axis and Hypothalamic Kiss-1 Gene Expression in Female Wistar Rats
Background: Saffron (Crocus sativus L.) is traditionally used as a spice for coloring and flavoring in cooking in some countries. One of the main component of saffron is Crocin. Recent researches have shown Crocin has various pharmacological effects. The aim of this study was to assess the effect of Crocin on the Pituitary-Gonadal Axis and Kiss-1 gene expression in hypothalamus and also ovarian...
متن کاملThe Effect of Vitex Agnuse Castus Fruit Powder on Hypothalamic GnRH Gene Expression in Laying Hens
Gonadotropin-releasing hormone (GnRH) is a key regulatory molecule of the hypothalamus–pituitary gonadal axis which induces transcription of luteinizing hormone (LH) from the anterior pituitary. Research has shown that estrogen plays an important role in regulating GnRH. Also, recent experiments indicated that Vitex agnus-castus (VAC) has high levels of phytoestrogen. Hence, this research was p...
متن کاملThe effect of intracerebroventricular administration of neuropeptide Y on reproductive axis function in the male Wistar rats: Involvement of hypothalamic KiSS1/GPR54 system
Several studies have shown that neuropeptide Y (NPY) is considered to be one of the key regulators of the hypothalamic-pituitary-gonadal axis in the mammals. Also, kisspeptin is a powerful upstream regulator of gonadotropin-releasing hormone neurons in the hypothalamus. The present study aims to investigate the effects of the intracerebroventricular (ICV) injection of NPY and BIBP3226 (NPY rece...
متن کاملPnm-12: Can Stress Lead to Infertility?
Background: The role that stress plays in infertility remains controversial and despite medical advances a large percentage of infertility remains unexplained. Clinicians and researchers consistently report that infertile women view infertility and its treatment as extremely stressful. Basic science has elucidated the linkages between the hypothalamic-pituitary axis (HPA) and hypothalamic-pitui...
متن کاملThe effect of 17 days exposure to static magnetic fields on the hypothalamic-pituitary-gonadal axis in the male rat
Power stations produce a range of magnetic fields more than 20 mT which are harmful to those working or living around them. Several investigators have reported an increased health risk due to exposure to electric and magnetic fields (EMF) at 50 and 60 Hz. Several studies have been reported especially with increased tumor incidence, effects on reproduction and development, and neural and behavio...
