Melatonin in energy control: Circadian time‐giver and homeostatic monitor

open access: yesJournal of Pineal Research, Volume 76, Issue 4, May 2024.
Abstract Melatonin is a neurohormone synthesized from dietary tryptophan in various organs, including the pineal gland and the retina. In the pineal gland, melatonin is produced at night under the control of the master clock located in the suprachiasmatic nuclei of the hypothalamus.

Homeobox gene‐encoded transcription factors in development and mature circadian function of the rodent pineal gland

open access: yesJournal of Pineal Research, Volume 76, Issue 3, April 2024.
Abstract Homeobox genes encode transcription factors that are widely known to control developmental processes. This is also the case in the pineal gland, a neuroendocrine brain structure devoted to nighttime synthesis of the hormone melatonin. Thus, in accordance with high prenatal gene expression, knockout studies have identified a specific set of ...

Distribution of gamma‐aminobutyric acid immunoreactivity in the brain of the Siberian sturgeon (Acipenser baeri): Comparison with other fishes

open access: yesJournal of Comparative Neurology, Volume 532, Issue 2, February 2024.
Inmunohistochemical methods showed that GABAergic cells, fibers, and terminals are widely distributed throughout the brain and spinal cord of the sturgeon. Comparison among sturgeon and other vertebrates, revealed numerous differences in the complexity of specific subsystems reflecting different trends followed by vertebrate brains during evolution ...
