an ancient chemical: serotonin effects on cell proliferation, maturation, and
apoptosis. Brain Res Bull 2001 Nov 15;56(5):413-24 "Evolutionarily,
serotonin existed in plants even before the appearance of animals. Indeed, serotonin
may be tied to the evolution of life itself, particularly through the role of
tryptophan, its precursor molecule. Tryptophan is an indole-based, essential amino
acid which is unique in its light-absorbing properties. In plants, tryptophan-based
compounds capture light energy for use in metabolism of glucose and the generation
of oxygen and reduced cofactors. Tryptophan, oxygen, and reduced cofactors combine
to form serotonin. Serotonin-like molecules direct the growth of light-capturing
structures towards the source of light. This morphogenic property also occurs
in animal cells, in which serotonin alters the cytoskeleton of cells and thus
influences the formation of contacts. In addition, serotonin regulates cell proliferation,
migration and maturation in a variety of cell types, including lung, kidney, endothelial
cells, mast cells, neurons and astrocytes). In brain, serotonin has interactions
with seven families of receptors, numbering at least 14 distinct proteins. Of
these, two receptors are important for the purposes of this review. These are
the 5-HT1A and 5-HT2A receptors, which in fact have opposing functions in a variety
of cellular and behavioral processes. The 5-HT1A receptor develops early in the
CNS and is associated with secretion of S-100beta from astrocytes and reduction
of c-AMP levels in neurons. These actions provide intracellular stability for
the cytoskeleton and result in cell differentiation and cessation of proliferation.
Clinically, 5-HT1A receptor drugs decrease brain activity and act as anxiolytics.
The 5-HT2A receptor develops more slowly and is associated with glycogenolysis
in astrocytes and increased Ca(++) availability in neurons. These actions destabilize
the internal cytoskeleton and result in cell proliferation, synaptogenesis, and
apoptosis. In humans, 5-HT2A receptor drugs produce hallucinations. The dynamic
interactions between the 5-HT1A and 5-HT2A receptors and the cytoskeleton may
provide important insights into the etiology of brain disorders and provide novel
strategies for their treatment." [Abstract]

C, Ross SB. Evidence for involvement of protein kinases in the regulation
of serotonin synthesis and turnover in the mouse brain in vivo.
J Neural Transm 2002 Nov;109(11):1353-63 "Inhibition of cAMP-dependent
protein kinase (PKA) with N-[2-methylamino)ethyl]-5-isoquinolinesulfonamide (H-8)
almost completely antagonized the increase in 5-HTP accumulation and 5-HIAA/5-HT
ratio in hypothalamus induced by NAS-181, a 5-HT(1B) receptor antagonist, but
had no effect when the mice were treated with NAS-181 together with WAY-100,635,
a selective 5-HT(1A) receptor antagonist. Inhibition of Ca(2+)-calmodulin-dependent
protein kinase (CaM kinase II) with the calmodulin antagonist N-(4-aminobutyl)-5-chloro-2-naphtalenesulfonamide
(W-13) did not antagonise the effect of NAS-181 alone, but counteracted that evoked
by the combined treatment with NAS-181 and WAY-100,635. The results indicate that
activation of tryptophan hydroxylase by reducing the tone from terminal 5-HT(1B)
receptors involves PKA whereas the depolarisation-induced activation of tryptophan
hydroxylase involves CaM kinase II. The increase in the 5-HIAA/5-HT ratio may
under the experimental conditions used suggest CaM kinase II-induced phosphorylation
of synapsin I resulting in increased 5-HT release." [Abstract]

of [125I]Iodocyanopindolol binding by cyanopindolol with an IC50 of 2.43 ±
0.81 nM. 5-HT1B receptors are the predominant type of serotonin receptors labeled
by [3H]5-HT in cultured DRG neurons, representing ~60% of the specific [3H]5-HT
binding sites. In addition, 5-HT1D and 5-HT2A receptor binding was also found
in these neurons. RT-PCR analysis of RNA isolated from embryonic sensory neurons
in culture confirmed the expression of 5-HT1B, 5-HT1D and 5-HT2A receptor mRNA.
It also demonstrated the presence of 5-HT1F, 5-HT2C, 5-HT3, 5-HT4, 5-HT5A and
5-HT5B receptor mRNA and the absence of 5-HT1A, 5-HT1E, 5-HT2B, 5-HT6 and 5-HT7

Peroutka SJ, Howell TA. The molecular
evolution of G protein-coupled receptors: focus on 5-hydroxytryptamine receptors.
Neuropharmacology 1994 Mar-Apr;33(3-4):319-24 "Phylogenetic comparisons
between homologous proteins can provide information on the rates of molecular
evolution of the proteins. G protein-coupled receptors are a "superfamily"
of proteins which exist in species ranging from yeast to man. Based on an analysis
of the percentage of amino acid homology between various species, the rate of
molecular evolution of G protein-coupled receptors can be estimated at approx
1% per 10 million years. Based on this assumption, the primordial 5-HT receptor
must have evolved more than 700-800 million years ago since the 3 major classes
of G protein-coupled 5-HT receptors (i.e. 5-HT1, 5-HT2 and 5-HT6 receptors) are
less than 25% homologous. 5-HT5, 5-HT7, 5-HTsnail, 5-HTdro and 5-HT1A receptors
differentiated approx 600-700 million years ago, the time period during which
vertebrates diverged from invertebrates. The mammalian 5-HT receptor subtypes
have differentiated over the past 90 million years. Thus, although a recent flurry
of "new" 5-HT receptors have appeared in the literature, the first "primordial"
5-HT receptor evolved over 750 million years ago, a date which likely predates
the evolution of muscarinic, dopaminergic and adrenergic receptor systems. This
analysis also predicts that a significant number of both mammalian and invertebrate
G protein-coupled 5-HT receptor subtypes remain to be identified." [Abstract]
