Prenatal undernutrition decreases the sensitivity of the hypothalamo-pituitary-adrenal axis in rat, as revealed by subcutaneous and intra-paraventricular dexamethasone challenges
(2007)
Prenatal undernutrition is known to disturb the hypothalamo-pituitary-adrenal (HPA) axis, possibly through the programming of decreased expression of hypothalamic and pituitary glucocorticoid receptors. To test this ...
Central NOS inhibition differentially affects vasopressin gene expression in hypothalamic nuclei in septic rats
(ELSEVIER SCIENCE BV, 2010)
Our aim was to investigate the effect of central NOS inhibition on hypothalamic arginine vasopressin (AVP) gene expression, hormone release and on the cardiovascular response during experimental sepsis. Male Wistar rats ...
Paraventricular nucleus mediates pressor response to noradrenaline injection into the dorsal periaqueductal gray area
(ELSEVIER SCIENCE BV, 2009)
The dorsal periaqueductal gray area (dPAG) is involved in cardiovascular modulation. In a previous study, we reported that noradrenaline (NA) microinjection into the dPAG of rats caused pressor response that was mediated ...
Ghrelin Indirectly Activates Hypophysiotropic CRF Neurons in Rodents
(Public Library of Science, 2012-02)
Ghrelin is a stomach-derived hormone that regulates food intake and neuroendocrine function by acting on its receptor, GHSR (Growth Hormone Secretagogue Receptor). Recent evidence indicates that a key function of ghrelin ...
Hypophagia induced by glucocorticoid deficiency is associated with an increased activation of satiety-related responses
(AMER PHYSIOLOGICAL SOC, 2009)
Uchoa ET, Sabino HA, Ruginsk SG, Antunes-Rodrigues J, Elias LL. Hypophagia induced by glucocorticoid deficiency is associated with an increased activation of satiety-related responses. J Appl Physiol 106: 596-604, 2009. ...
Role of macrophage inhibitory factor (MIF) in the hypothalamic paraventricular nucleus (PVN) in blood pressure changes induced by hyperosmolality or hypovolemia
(Federation Amer Soc Exp Biol, 2011-04-01)
Renal effects of angiotensin II receptor subtype 1 and 2-selective ligands injected into the paraventricular nucleus of conscious rats
(1999-10-22)
We determined the effects of losartan and CGP42112A (selective ligands of the AT1 and AT2 angiotensin receptors, respectively) and salarasin (a relatively nonselective angiotensin receptor antagonist) on urinary volume and ...
