Pineal cyclic AMP and cyclic GMP are regulated by norepinephrine (NE) acting through alpha 1- and beta-adrenoceptors. beta-Adrenergic stimulation appears to be an absolute requirement and alpha 1-adrenergic activation amplifies beta-adrenergic stimul

In neonatal rat gonadotropes, melatonin inhibits gonadotropin-releasing-hormone (GnRH)-stimulated increase in intracellular Ca2+ concentration ([Ca2+]i); in cells transfected with the Mel1a melatonin receptor, however, melatonin has been shown to pot

Effects of melatonin on various manifestations of ischemia/reperfusion injury of the isolated perfused rat heart were examined. Ischemia- and reperfusion-induced ventricular arrhythmias were studied under constant flow in hearts subjected to 10, 15 o

Mammalian circadian pacemaker is located in suprachiasmatic nuclei (SCN) of the hypothalamus. The pacemaker is entrained by light-dark cycle; the photic information is transmitted primarily via the retino-hypothalamic tract (RHT). The main neurotrans

The rhythm of the pineal hormone melatonin transduces the effect of photoperiod on seasonal functions. Duration of the melatonin pulse provides information about season and the long melatonin pulse induces reproductive involution in the long day bree

The sensitivity of GnRH-stimulated calcium signaling to melatonin, in a subpopulation of neonatal gonadotrophs, is supposed to be attributable to melatonin receptors. However, it is not yet known whether the intracellular pathway for GnRH action in m

The effects of melatonin on pituitary adenylyl cyclase-activating polypeptide-induced increase of cyclic AMP and [Ca2+]i were studied in neonatal rat pituitary cells. The polypeptide increased cyclic AMP accumulation. In the presence of melatonin the
