چکیده

Objective: This study aims to explore the effects of light stress on the expression of Kisspeptin/GnRH in rat hypothalamus. Methods: The rat model of chronic stress was established through artificial illumination time. The rats were divided into control group, continuous light group, interval light group and reverse day and night group randomly. The expression levels of Kisspeptin and GnRH in rat hypothalamus were detected by RT-PCR, westernblotting and immunohistochemical methods. Results: The results showed that the expression levels of Kisspeptin and GnRH in rat hypothalamus significantly decreased in continuous light group and reverse day and night group (P<0.05), there was no difference between interval light group and control group (P>0.05). Conclusions: Long time light stress can decrease the expression levels of Kisspeptin and GnRH in rat hypothalamus.

Morphine and kisspeptin influences on 5-α reductase and aromatase gene expression in adult male rats

Objective(s): Kisspeptin and opioids are important factors for controlling GnRH/LH secretion. In present study, influences of kisspeptin or morphine were investigated on 5α- reductase or aromatase (CYP19) genes expression in the hypothalamus, testis and liver. It aimed to investigate whether kisspeptin pathway may control morphine effects on plasma concentration of tes...

P-222: Expression of RFamide-Related Peptide-3 and KiSS-1 mRNA in The Hypothalamus of Pregnant Rat

Background: There is no follicular development during pregnancy in the rat comparable to the changes of the estrous cycle. RFamide-related peptide-3 (RFRP-3) and kisspeptin were recognized as regulator of gonadotropin releasing hormone (GnRH) and luteinizing hormone (LH) secretion in several species, including the rat. The aim of the present study was to evaluate the relative expression of RFRP...

Lactation effect on the mRNAs expression of RFRP-3 and KiSS-1 in dorsomedial and arcuate nuclei of the rat hypothalamus

Introduction: Arginine-phenylalanine-amide-related peptide-3 (RFRP-3) and kisspeptin are believed to be inhibitor and stimulator of gonadotropin releasing hormone (GnRH) secretion, respectively. The aim of the present study was to compare the effect of lactation on the expression of RFRP-3 mRNA in dorsomedial hypothalamic nucleus (DMH) and KiSS-1 mRNA in arcuate nucleus (ARC) of hypothalamus...

Long term malnutrition and mRNAs expression of RFRP-3 and KiSS-1 in hypothalamus of female ovariectomized rats

Introduction: Arginine-phenylalanine-amide-related peptide-3 (RFRP-3) is an inhibitor of gonadotropin releasing hormone (GnRH) secretion and an appetizer. Kisspeptin is a stimulator of GnRH and a regulator of energy metabolism. The objectives of the present study were to compare the effect of long term malnutrition on expression of RFRP-3 mRNA in dorsomedial hypothalamic nucleus (DMH) and Ki...

Regulation of kisspeptin and gonadotropin-releasing hormone expression in rat placenta: study using primary cultures of rat placental cells

BACKGROUND Gonadotropin-releasing hormone (GnRH) and kisspeptin in the hypothalamus are thought to be crucial components of the hypothalamic-pituitary-gonadal (HPG) axis and maintain reproductive function. These neuropeptides are also expressed in the placenta, where they may contribute to placental physiology. In this study, we examined how these peptides are regulated within the placenta. M...
