Expression and cellular localization of the transcription factor NeuroD1 in the developing and adult rat pineal gland [PDF]

open access: yes, 2015
Circadian rhythms govern many aspects of mammalian physiology. The daily pattern of melatonin synthesis and secretion is one of the classic examples of circadian oscillations.

Zebrafish embryonically exposed to valproic acid present impaired retinal development and sleep behavior

open access: yesAutism Research, Volume 16, Issue 10, Page 1877-1890, October 2023., 2023
Abstract Prenatal exposure to valproic acid (VPA), a drug widely used to treat epilepsy and bipolar disorder, is an environmental risk factor for autism spectrum disorder (ASD). VPA has been used to reproduce the core symptoms of ASD in animal model organisms, including zebrafish.

The Pinealocyte-A Paraneuron ? A Review

open access: yesArchivum histologicum japonicum, 1977
The pineal complex develops from a tubular evagination of the diencephalic roof. In amphibians a proliferation zone is the source of the pinealocytes and of the cells of the subcommissural organ. The pinealocytes are not real nerve cells, but derived likewise from the embryonic neural epithelium.

Role and neural regulation of clock genes in the rat pineal gland: Clock modulates amplitude of rhythmic expression of Aanat encoding the melatonin‐producing enzyme

open access: yesJournal of Pineal Research, Volume 75, Issue 2, September 2023., 2023
Abstract Circadian clock gene expression in the suprachiasmatic nucleus (SCN) controls 24 h rhythms in body functions, but clock genes are also expressed in extra‐hypothalamic tissues, including the melatonin‐producing pineal gland. The nocturnal increase in pineal melatonin synthesis is a hallmark in circadian biology, but the role of local clock gene

BMAL1 but not CLOCK is associated with monochromatic green light-induced circadian rhythm of melatonin in chick pinealocytes

open access: yesEndocrine Connections, 2019
The avian pineal gland, an independent circadian oscillator, receives external photic cues and translates them for the rhythmical synthesis of melatonin.

Protein and mRNA expression of gonadotropin-releasing hormone receptor in yaks during estrus

open access: yesRevista Brasileira de Zootecnia, 2018
To demonstrate the role of gonadotropin-releasing hormone (GnRH) in yaks (Bos grunniens), we characterized the expression of gonadotropin-releasing hormone receptor (GnRHR) mRNA and protein.

Adrenergic control of pinealocyte chondriome – an in vitro study [PDF]

open access: yesPolish Journal of Veterinary Sciences, 2016
Abstract Norepinephrine released from sympathetic innervation plays the main role in the regulation of melatonin secretion in mammalian pinealocytes. The present study was conducted for the following reasons: 1) to establish whether the pinealocyte chondriome is controlled by norepinephrine, 2) to determine the effect of adrenergic stimulation on ...

Melatonin receptor (MTNR1A and MTNR2B) expression during the breeding season in the yak (Bos grunniens)

open access: yesCzech Journal of Animal Science, 2014
Melatonin plays key roles in a wide range of mammalian body functions, which are mediated by the melatonin-specific cell surface receptor (MTNR1A and MTNR1B).

Active zone proteins are dynamically associated with synaptic ribbons in rat pinealocytes [PDF]

open access: yes, 2008
Synaptic ribbons (SRs) are prominent organelles that are abundant in the ribbon synapses of sensory neurons where they represent a specialization of the cytomatrix at the active zone (CAZ).
