Roles of 5-hydroxytryptamine and dopamine as neurotransmitters eliciting release of erythrophorotropic hormones in the fiddler crab, UCA pugilator.
TLDR
The data obtained with 5-HT and DA agonists and antagonists on red pigment translocation in vivo and in vitro, are consistent with their neurotransmitter candidacies in evoking the release of these erythrophorotropic hormones.About:

Journal ArticleDOI
Regulation of neurohormone release in the fiddler crab, Uca pugilator: effects of gamma-aminobutyric acid, octopamine, Met-enkephalin, and beta-endorphin.
TL;DR: Gamma-aminobutyric acid (GABA) blocked concentration of the pigments in melanophores and erythrophores of intact crabs andOctopamine (OA) blocked black pigment dispersion in intact crabs, but did not affect red pigment disp immersion or concentration.

The occurrence, synthesis and metabolism of 5-hydroxytryptamine and 5-hydroxytryptophan in the cestode Hymenolepis diminuta: A high performance liquid chromatographic study
Paula Ribeiro,Rodney A. Webb +1 more
TL;DR: The biosynthesis and metabolism of 5-hydroxytryptamine (serotonin; 5-HT) in the cestode Hymenolepis diminuta was investigated by High Performance Liquid Chromatography (HPLC) and tissue levels were significantly depressed when the animals were deprived of tryptophan.
Journal ArticleDOI
Serotonin binding sites. I. Structures of sites on myelin basic protein, LHRH, MSH, ACTH, interferon, serum albumin, ovalbumin and red pigment concentrating hormone.
TL;DR: Structural and functional similarities between the tryptophan peptide, LHRH, and MSH-ACTH with an ACTH-like peptide of human leukocyte interferon, with human and bovine serum albumin, hen ovalbumin, and with red pigment concentrating hormone suggest that the latter peptides may also contain similar serotonin binding sites.

Circadian oscillations of RPCH gene expression in the eyestalk of the crayfish Cherax quadricarinatus.
TL;DR: Single cosinor analysis supports the notion of beta-actin and RPCH mRNA circadian behavior in animals subjected to 12h:12h light/dark regimes and in constant darkness RPCH RNA concentration changes to ultradian cycles.
Journal ArticleDOI
Opioid potentiated chromatophorotropin regulation of pigment migration in the land crab Gecarcinus lateralis.
TL;DR: Results in Gecarcinus lateralis dopamine treatment strongly indicate the presence of a dopamine receptor mediated system in this organism, and indicate that an endogenous opioid system may be part of the overall regulation of pigmentation movement.

p-CHLOROPHENYLALANINE: A SPECIFIC DEPLETOR OF BRAIN SEROTONIN
B K Koe,A Weissman +1 more
TL;DR: The results suggest that p -chlorophenylalanine may effect 5HT depletion by inhibiting the biosynthesis of this monoamine, possibly by blocking tryptophan hydroxylation.

Receptor activity and turnover of dopamine and noradrenaline after neuroleptics.
TL;DR: The most potent and specific neuroleptics seemed to influence mainly the brain DA mechanisms, both functionally and chemically.

The central effects of a novel dopamine agonist.
TL;DR: The results suggest that SK & F 38393 may selectively stimulate supersensitive central dopamine receptors in vivo or may activate only a certain subclass of dopamine receptors including the receptor in the renal vasculature and the adenylate cyclase coupled postsynaptic receptors in the caudate.
