Multiunit activity (MUA) of arcuate nucleus and cortical EEG were recorded in the regularly cycling female rats on the day of proestrous under urethane anaesthesia. The MUA was compared before and after injection of beta-endorphin in third ventricle. In some animals MUA increased after 30-40 min and persisted for 3-4 hr, in others MUA got inhibited within 5-10 min of injection of beta-Endorphin...
Hypothalamic neuropeptide Y (NPY) activity is believed to play an important role in the response to food deprivation in adult rats. Little is known, however, about the role of the hypothalamic NPY system in the control of food intake in the preweanling rat. To address this issue, we examined the effect of deprivation on arcuate nucleus preproNPY expression in lean Zucker rat pups, using in situ...
Correction of the obese state induced by genetic leptin deficiency reduces elevated levels of both blood glucose and hypothalamic neuropeptide Y (NPY) mRNA in ob/ob mice. To determine whether these responses are due to a specific action of leptin or to the reversal of the obese state, we investigated the specificity of the effect of systemic leptin administration to ob/ob mice (n = 8) on levels...
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 KiSS-...
