Circadian regulation of Kiss1 neurons: implications for timing the preovulatory gonadotropin-releasing hormone/luteinizing hormone surge.
The preovulatory GnRH/LH surge depends on the presence of estradiol (E(2)) and is gated by a circadian oscillator in the suprachiasmatic nucleus (SCN) that causes the surge to occur within a specific temporal window. Although the mechanisms by which the clock times the LH surge are unclear, evidence suggests that the SCN is linked to GnRH neurons through a multisynaptic pathway that includes ne...
متن کاملCircadian Gene Expression in the Suprachiasmatic Nucleus 901 Circadian Gene Expression in the Suprachiasmatic Nucleus
Regulated expression of a core set of clock genes is the basis of circadian timekeeping in vertebrates, as in other organisms. Clock genes are defined as being necessary to generate normal circadian rhythms, near 24 h oscillations in biological processes. With the enlargement of the brain in vertebrates, control of circadian rhythms became centralized. In lower vertebrates, such as fishes, liza...
متن کاملPhenobarbital blockade of the preovulatory luteinizing hormone surge: association with phase-advanced circadian clock and altered suprachiasmatic nucleus Period1 gene expression.
The suprachiasmatic nucleus (SCN) controls the timing of the preovulatory luteinizing hormone (LH) surge in laboratory rodents. Barbiturate administration during a critical period on proestrus delays the surge and prolongs the estrous cycle 1 day. Because a nonphotic timing signal (zeitgeber) during the critical period that phase advances activity rhythms can also induce the latter effect, we h...
متن کاملKiss1 neurons in the forebrain as central processors for generating the preovulatory luteinizing hormone surge.
Kisspeptins are neuropeptides encoded by the Kiss1 gene, which have been implicated in the neuroendocrine regulation of gonadotropin-releasing hormone (GnRH) secretion. The goal of this study was to test the hypothesis that activation of Kiss1 neurons in the anteroventral periventricular nucleus (AVPV) is linked to the induction of the preovulatory luteinizing hormone (LH) surge in the rat. Fir...
متن کاملCircadian Timing of REM Sleep Is Coupled to an Oscillator within the Dorsomedial Suprachiasmatic Nucleus
Sleep is consistently concentrated to a specific time of the day. Its timing and consolidation depend on the interplay between a homeostatic and a circadian process of sleep regulation [1-3]. Sleep propensity rises as a homeostatic response to increasing wake time, whereas a circadian clock determines the specific time when sleep will probably occur. This two-process regulation of sleep also de...
