In the mammalian pineal gland, information on environmental lighting conditions that is neuronally encoded by the retina is converted into nocturnally elevated synthesis of the hormone melatonin. Evolutionary pressure has changed the morphology of vertebrate pinealocytes, eliminating direct photoreception and the endogenous clock function. Despite these changes, nocturnally elevated melatonin synthesis has remained a reliable indicator of time throughout evolution. In the photo-insensitive… Expand

Topics from this paper

Circadian regulation of pineal gland rhythmicity
TLDR
This review will focus on the central and pineal mechanisms in generation of mammalian pineal rhythmicity including melatonin production as well as local control of serotonin and melatonin rhythms. Expand
A survey of molecular details in the human pineal gland in the light of phylogeny, structure, function and chronobiological diseases
TLDR
A remnant silhouette of premortem dynamics within the hormone’s biosynthesis pathway can be constructed and protein‐protein interactions and nucleo‐cytoplasmic protein shuttling indicate furthermore a novel twist in the molecular dynamics in the cells of this neuroendocrine brain structure. Expand
Signaling within the pineal gland: A parallelism with the central nervous system.
TLDR
It is suggested that applying this comparative approach to additional PG regulators may be a useful tool for understanding complex areas of the brain, as well as the influence of the PG in both health and disease, including circadian functions and disorders. Expand
The pineal gland from development to function.
TLDR
The pineal gland is a small neuroendocrine organ whose main and most conserved function is the nighttime secretion of melatonin, and which appears to have lost several functions in relation to light and temperature, which are important in lower vertebrate species. Expand
Modulation of Aanat gene transcription in the rat pineal gland
  • A. Ho, C. Chik
  • Biology, Medicine
  • Journal of neurochemistry
  • 2010
TLDR
The pineal gland is highlighted as an excellent model system for studying neurotransmitter‐regulated rhythmic gene expression and signaling mechanisms involving modification of constitutively expressed proteins and those requiring synthesis of new proteins are reviewed. Expand
Day–night expression patterns of clock genes in the human pineal gland
Abstract:  Rhythm generation within the mammalian circadian system is achieved by clock genes and their protein products. As an integral part of this system, the pineal gland serves the need to tuneExpand
Characterization of human pineal gland proteome.
TLDR
An unbiased global proteomic profile of this biomedically important organ should benefit molecular research to unravel the role of the pineal gland in neuropsychiatric and neurodegenerative diseases. Expand
Night/Day Changes in Pineal Expression of >600 Genes
TLDR
Functional categorization of the highly expressed and/or night/day differentially expressed genes identified clusters that are markers of specialized functions, including the immune/inflammation response, melatonin synthesis, photodetection, thyroid hormone signaling, and diverse aspects of cellular signaling and cell biology. Expand
Transcription factor dynamics in pineal gland and liver of the Syrian hamster (Mesocricetus auratus) adapts to prevailing photoperiod
TLDR
In the Syrian hamster transcription factor expression patterns lock onto the prevailing photoperiod in two peripheral oscillators, the pineal gland and the liver, to function as mediators of suprachiasmatic nucleus‐derived information on environmental light and dark. Expand
Circadian dynamics of the cone-rod homeobox (CRX) transcription factor in the rat pineal gland and its role in regulation of arylalkylamine N-acetyltransferase (AANAT).
TLDR
The data indicate that the rhythmic nature of pineal CRX protein may directly modulate the daily profile of Aanat expression by inducing nighttime expression of this enzyme, thus facilitating nocturnal melatonin synthesis in addition to its role in ensuring a correct tissue distribution of AAnat expression.

Melatonin Synthesis in the Human Pineal Gland: Advantages, Implications, and Difficulties
TLDR
Post‐mortem pineal material seems to constitute a valid approach to decipher the regulation of human melatonin synthesis, and the molecular elements involved in shaping the rhythmic hormone synthesis cannot be analyzed experimentally in the living organism. Expand
Photoreception and circadian clock system of the chicken pineal gland
TLDR
The recent characterization of the chick pineal clock genes strongly suggests that they constitute a transcription/translation‐based autoregulatory feedback loop, which is very similar to that generating circadian rhythmicity in mammalian SCN. Expand
The Pineal Organ, Its Hormone Melatonin, and the Photoneuroendocrine System
TLDR
The functional significance of the melatonin-synthesizing pineal organ as an important component of the photoneuroendocrine system is confirmed and the importance of this organ as a model to study signal transduction mechanisms both in photoreceptors and in neuroendocrine cells is stressed. Expand
Signal Transduction in The Rodent Pineal Organ
TLDR
The data gained by molecular biology, immunohistochemistry and single-cell imaging demonstrate a time-and substance-specific activation of these signaling pathways and provide a framework for the understanding of the complex signal transduction cascades in the rodent pineal gland. Expand
Photic and Circadian Regulation of Retinal Melatonin in Mammals
TLDR
How the photic environment and the circadian clock interact in determining melatonin levels is discussed, in addition to the role that melatonin plays in retinal physiology. Expand
Developmental Expression Pattern of Phototransduction Components in Mammalian Pineal Implies a Light-Sensing Function
TLDR
All of the components needed to reconstitute a functional phototransduction pathway are expressed in the majority of neonatal pinealocytes, although the expression levels of many of these genes decline dramatically during development, supporting the theory that the neonatal rat pineal itself is photosensitive.

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
Otx5 regulates genes that show circadian expression in the zebrafish pineal complex
TLDR
It is shown that crx and otx5 orthologs are expressed in both the pineal organ and the asymmetrically positioned parapineal of larval zebrafish, indicating that Otx5 rather than Crx regulates genes that show circadian expression in the zebra fish pineal complex. Expand
Generation of the Melatonin Endocrine Message in Mammals: A Review of the Complex Regulation of Melatonin Synthesis by Norepinephrine, Peptides, and Other Pineal Transmitters
TLDR
The aim of this review is to gather together early and recent data on the effects of the nonadrenergic transmitters on modulation of melatonin synthesis, which reveals the variety of inputs that can be integrated by the pineal gland; what elements are crucial to deliver the very precise timing information to the organism.

Efforts toward elucidating the molecular instrumentation intrinsic to the pineal gland, back to back with those to the retina, should lead to a comprehensive understanding of the evolutionary history of the vertebrate photoreceptive structures. Expand
