Abstract. The avian pineal gland, like that of mammals, displays a striking circadian rhythm in the synthesis and release of the hormone melatonin. However, the pineal gland plays a more prominent role in avian circadian organization and differs from that in mammals in several ways. One important difference is that the pineal gland in birds is relatively autonomous. In addition to making melatonin, the avian pineal contains photoreceptors and a circadian clock (thus, an entire circadian system… Expand
Circadian genomics of the chick pineal gland in vitro
TLDR
It is hypothesized that the pineal circadian transcriptome is reduced but functionally conserved in vitro, and supports an endogenous role for the Pineal in regulating local rhythms in metabolism, immune function, and other conserved pathways. Expand
Avian photoreceptors and their role in the regulation of daily and seasonal physiology.
TLDR
Limited evidence that is available on the roles of encephalic or deep brain photoreceptors in the regulation of circadian and seasonal physiology is reviewed, with particular emphasis placed on the DBPs. Expand
Retinal illumination phase shifts the circadian rhythm of serotonin N-acetyltransferase activity in the chicken pineal gland
TLDR
The results suggest that in the chicken retinally perceived light provides a powerful and important signal for synchronization of circadian rhythmicity in the pineal gland. Expand
Clock gene mRNA and protein rhythms in the pineal gland of mice
TLDR
The idea that in this tissue PER1 may have a trigger function for initiating the cycles of the clockwork's transcriptional/translational feedback loops is put forward. Expand
Daily rhythm and regulation of clock gene expression in the rat pineal gland.
TLDR
Data show that the expression of Per1 and Cry2 in the rat pineal gland is regulated by the clock-driven changes in norepinephrine, in a similar manner to the melatonin rhythm-generating enzyme arylalkylamine N-acetyltransferase. Expand
Roles for extra -hypothalamic oscillators in the avian clock
TLDR
The experimental work presented in this dissertation uses the domestic chicken, Gallus domesticus, as a model to address roles for Extra-Hypothalamic Oscillators in the Avian Clock and carry forward current understanding about circadian biology in this species. Expand
Research report Daily rhythm and regulation of clock gene expression in the rat pineal gland
TLDR
Data show that the expression of Per1 and Cry2 in the rat pineal gland is regulated by the clock-driven changes in norepinephrine, in a similar manner to the melatonin rhythm-generating enzyme arylalkylamine N-acetyltransferase. Expand
Effect of monochromatic light on the temporal expression of N-acetyltransferase in chick pineal gland
TLDR
It is demonstrated that monochromatic light affects the daily expression of cAanat in the chick pineal gland via the biological clock by affecting the levels of clock regulators via entraining the expression of pineal glands opsins. Expand
Regulation of serotonin N-acetyltransferase activity in the chick pineal gland by UV-A and white light: role of MK-801- and SCH 23390-sensitive retinal signals.
TLDR
Ocular exposure of chicks to UV-A radiation or white light during the second half of the subjective night markedly decreased AANAT activity in the pineal gland, and produced a significant phase advance of the circadian rhythm of the enzyme activity. Expand
Circadian gene expression patterns of melanopsin and pinopsin in the chick pineal gland.
TLDR
Whereas the daily rhythm of pinopsin gene expression is dually regulated by light plus the intrapineal circadian oscillator, that of melanopsin appears to depend solely on the oscillator. Expand

A circadian oscillator in cultured cells of chicken pineal gland
TLDR
In the dispersed cell culture of chicken pineal gland, N-acetyltransferase activity exhibits a circadian rhythm and responds to enviromental lighting in the same manner as in the organ culture. Expand

Cloned chicken pineal cDNA encoding the photoreceptive molecule is cloned and it is confirmed that it is a pineal photosensor and named pinopsin, indicating a similarity between retinal rod cells and pinealocytes in the phototransduction pathway. Expand

TLDR
The identified circadian clock genes in Japanese quail are identified and demonstrated that these genes are expressed in known circadian oscillators, the pineal and the retina, and this results indicate that the mSCN is a circadian oscillator in birds. Expand

TLDR
Research indicates that the circadian rhythms of many species of reptiles, birds and mammals, including humans, are synchronized by the administration of exogenous melatonin, and points to the possibility that melatonin or melatonin analogues may be therapeutically useful for the control of circadian clock dysfunctions such as jet lag, shift-work syndrome and sleep disorders.

The mammalian retina as a clock
TLDR
The identification of a group of genes that are believed to constitute the molecular core of the circadian clock in the retina, although with a slightly different 24-h profile from that observed in the central circadian pacemaker, suggests that some difference may exist between the retinal clock and the clock located in the suprachiasmatic nuclei of hypothalamus.

It is determined that the chicken AA‐ NAT mRNA is detectable in follicular pineal cells and retinal photoreceptors and that it exhibits a circadian rhythm, with peak levels at night, and that changes in mRNA content are not involved in the rapid light‐induced decrease in AA‐NAT activity. Expand
