introduction: numerous studies have demonstrated that kisspeptin, a peptide from the kiss1 gene, plays an important role in regulating the secretion of gonadotropin releasing hormone (gnrh). also, there is some evidence suggesting that kisspeptin can interact with other neuropeptides for the control of the reproductive axis. in the present study, we have investigated the effect of central admin...
Kisspeptin is the peptide product of KISS-1 gene and endogenous agonist for Kiss1 receptor. It well known that kisspeptin acts centrally, stimulates secretion gonadoliberin (GnRH). Further, also interacts with other neuropeptides such as neurokinin B dynorphin to regulate GnRH pulse generation plays a key role in sexual behavior. This study aimed evaluate effect on male rats' motivation its dep...
Kisspeptins are a group of peptides that stimulate GnRH release and are required for puberty and maintenance of normal reproductive function. This review focuses on our understanding of the way in which kisspeptin signaling regulates mammalian fertility and how they act as central integrators of different hormonal and physiological signals.
The kiss1 peptide (kisspeptin), a product of the kiss1 gene, is one of the key neuropeptides regulating vertebrate reproduction. In 2009, we identified a paralogous gene of kiss1 in the brain of amphibians and named it kiss2. Currently, the presence of the kiss2 gene and the kiss2 peptide is still obscure in amniotes compared with that in other vertebrates. Therefore, we performed genome databa...
Hypothalamic kisspeptin neurons integrate and translate cues from the internal and external environments that regulate gonadotropin-releasing hormone (GnRH) secretion and maintain fertility in mammals. However, the intracellular signaling pathways utilized to translate such information into changes in kisspeptin expression, release, and ultimately activation of the kisspeptin-receptive GnRH net...
The brain mechanism regulating gonadotropin-releasing hormone (GnRH)/luteinizing hormone (LH) release is sexually differentiated in rodents. Kisspeptin neurons in the anteroventral periventricular nucleus (AVPV) have been suggested to be sexually dimorphic and involved in the GnRH/LH surge generation. The present study aimed to determine the significance of neonatal testicular androgen to defem...
Objective The inhibitory effects of Morphine and the stimulatory influence of kisspeptin signaling have been demonstrated on GnRH/LH release. Hypothalamic kisspeptin is involved in relaying the environmental and metabolic information to reproductive axis. In the present study the role of kisspeptin/GPR54 signaling system was investigated on relaying the inhibitory effects of morphine on LH horm...
