Background: RFamide-related peptide-3 (RFRP-3) inhibits gonadotropin releasing hormone (GnRH) and luteinizing hormone (LH) secretion in rats. This study evaluates the effects of litter size and suckling intensity on RFRP mRNA expression in the dorsomedial hypothalamic nucleus (DMH) of rats.
Materials And Methods: A total of 32 pregnant and 4 non-lactating ovariectomized (control group) Sprague-Dawley rats were used in this experimental study.
Objectives: The effect of litter size and suckling intensity on the expression of KiSS-1 mRNA in the arcuate nucleus (ARC) of rats were evaluated.
Materials And Methods: Thirty two pregnant and four non-lactating ovariectomized (as control group) rats were used in this experiment. Lactating rats were allotted to eight equal groups.
