Kisspeptin/metastin has been implicated as a critical regulator in luteinizing hormone (LH) secretion and the reproductive system mediating the effect of estrogen on GnRH neurons. In the present study we examined the sex differences in the effects of

The expression of Kiss1 in the anteroventral periventricular nucleus (AVPV) and its product, metastin/kisspeptin, show a circadian pattern with a peak in the evening, which shows a strong phase relationship with the time of the gonadotropin-releasing

Photic resetting of a biological clock is one of the fundamental characteristics of circadian systems and allows living organisms to adjust to a particular environment. Nocturnal light induces the Per1 and Per2 genes, which leads to a resetting of th

Although it is known that glucocorticoids induce differentiation of growth hormone (GH)-producing cells in rodents and birds, the effect of mineralocorticoids on GH mRNA expression and the origin of corticosteroids affecting somatotrope differentiati

The suprachiasmatic nucleus (SCN) is the neuroanatomical locus of the mammalian circadian pacemaker. Here we demonstrate that an abrupt shift in the light/dark (LD) cycle disrupts the synchronous oscillation of circadian components in the rat SCN. Th

Melatonin is an important hormone regulating circadian clocks in birds, but the specific cellular sites of action are not completely known. The present study was designed to determine whether astrocytes derived from chick brain contained functional m

The mammalian circadian oscillator is composed of interacting positive and negative transcription events. The clock proteins PER1 and PER2 play essential roles in a negative limb of the feedback loop that generates the circadian rhythm in mammals. In

Electrospraying is performed by applying a high voltage to a capillary tip. A highly charged droplet at the capillary tip splits into microor nanoscale droplets, and a charged fineliquid aerosol is accelerated by a high-voltage electric field. This m

In order to study the mechanisms of ocular circadian rhythms in the pigeon, we measured melatonin and dopamine simultaneously from the eye using in vivo microdialysis. In experiment 1, the phase relationship between circadian rhythms of ocular melato
