... and dibutyryl-cAMP induce PDE10A mRNA, the in vitro clock-dependent control of Pde10a appears to be mediated via a norepinephrine → β-adrenoceptor → cAMP/protein kinase A signaling pathway. With regard to the physiological role of PDE10A in the pineal gland, the specific PDE10A inhibitor papaverine was seen...

... of receptors; exogenous melatonin and norepinephrine increased NR; β-endorphin increased only NR, but methionine enkephalin stimulated both, and epithalamine had no significant effects on either group of receptors, but thymosin α 1 increased NR. The results from the current study demonstrate that while all...

.... The postovariectomy rise in LH and FSH was severely attenuated in the diabetic rats. EB treatment was more effective in lowering LH and FSH levels in the diabetic as compared to the control rats. Median eminence (ME) norepinephrine (NE) and dopamine (DA) turnover was higher in the oil-treated diabetic rats than oil...

... treated rats, and the effect of DDC on the P-induced GnRH mRNA levels was examined. A single injection of P into OVX + E primed rats augmented norepinephrine (NE) content, while the administration of DDC effectively blocked the P-induced increase in NE content, along with the increase in dopamine content...

.... In these experiments, the TMN was electrically stimulated in conscious rats and HA release in the region of the supraoptic nucleus (SON) was estimated using in vivo microdialysis. In addition, mean arterial blood pressure (MAP), heart rate (HR), and plasma concentrations of norepinephrine (NE) and vasopressin (VP...

Finally, estradiol enhanced the excitability of laterally projecting neurons, which have been implicated in lordosis...

... minutes. However, when given after the injection of phenoxybenzamine, naloxone failed to induce such immediate MUA volleys. These changes in the intervals between the MUA volleys were faithfully reflected by the pulsatile LH secretion. These results suggest that norepinephrine facilitates LHRH pulse...

...Susan L. Stoddard; Valerie K. Bergdall Seventy-five sites were electrically stimulated within the preoptic and hypothalamic areas of anesthetized cats (n = 16). Adrenolumbar venous blood flow, secretion of epinephrine and norepinephrine, heart rate and mean arterial blood pressure were measured...

... rats. To localize the HPA axis defect to the hypothalamic CRH neuron, we evaluated the ability of explanted hypothalami from the two strains to secrete immunoreactive CRH in vitro, in response to acetylcholine (ACh), norepinephrine (NE), 5-HTand the 5-HT agonist quipazine. LEW/N hypothalami released...
